Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a></em></p> <p>Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike.</p> <p>Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog.</p> <p>I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets.</p> <h2>Breed and age differences</h2> <p>Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia.</p> <p>Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat.</p> <p>Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather.</p> <h2>When is my dog too cold?</h2> <p>Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable.</p> <p>Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>.</p> <p>Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog.</p> <p>Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it.</p> <h2>Road salt dangers</h2> <p>Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws.</p> <p>Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs.</p> <p>Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation.</p> <h2>Antifreeze risks</h2> <p><a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing.</p> <p>Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>.</p> <p>There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment.</p> <p>When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time.</p> <p>Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.<!-- Below is The Conversation's page counter tag.

How tracking menopause symptoms can give women more control over their health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/deborah-lancastle-1452267">Deborah Lancastle</a>, <em><a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a></em></p> <p>Menopause can cause more symptoms than hot flushes alone. And some of your symptoms and reactions might be due to the menopause, even if you are still having periods. Research shows that keeping track of those symptoms can help to alleviate them.</p> <p>People sometimes talk about the menopause as though it were a single event that happens when you are in your early 50s, which is <a href="https://www.mayoclinic.org/diseases-conditions/menopause/symptoms-causes/syc-20353397#:%7E:text=Menopause%20is%20the%20time%20that,is%20a%20natural%20biological%20process.">the average time</a> to have your last period. But the menopause generally stretches between the ages of 45 and 55. And some women will experience an earlier “medical” menopause because of surgery to remove the womb or ovaries.</p> <p>The menopause often happens at one of the busiest times of life. You might have teenagers at home or be supporting grown-up children, have elderly parents, be employed and have a great social life. If you feel exhausted, hot and bothered, irritable and can’t sleep well, you might be tempted to think that it is because you never get a minute’s peace. But that is why monitoring symptoms is important.</p> <p><a href="https://journals.lww.com/menopausejournal/Abstract/2023/03000/Symptom_monitoring_improves_physical_and_emotional.7.aspx">My team recently tested</a> the effects of tracking symptoms and emotions during the menopause. We asked women to rate 30 physical and 20 emotional symptoms of the menopause.</p> <p>The physical and psychological symptoms included poor concentration, problems with digesting food, stress and itchy skin, as well as the obvious symptoms like hot flushes and night sweats. Women tracked positive emotions like happiness and contentment, and negative emotions like feeling sad, isolated and angry.</p> <p>There were two groups of women in this study. One group recorded their symptoms and emotions every day for two weeks. The other group recorded their symptoms and emotions once at the beginning of the fortnight and once at the end.</p> <p>The results showed that the women who monitored their symptoms and emotions every day reported much lower negative emotions, physical symptoms and loneliness at the end of two weeks than at the beginning, compared to the other group.</p> <p>As well as this, although the loneliness scores of the group who monitored every day were lower than the other group, women in both groups said that being in the study and thinking about symptoms helped them feel less lonely. Simply knowing that other women were having similar experiences seemed to help.</p> <p>One participant said: “I feel more normal that other women are doing the same survey and are probably experiencing similar issues, especially the emotional and mental ones.”</p> <h2>Why does monitoring symptoms help?</h2> <p>One reason why tracking might help is that rating symptoms can help you notice changes and patterns in how you feel. This could encourage you to seek help.</p> <p>Another reason is that noticing changes in symptoms might help you link the change to what you have been doing. For example, looking at whether symptoms spike after eating certain foods or are better after exercise. This could mean that you change your behaviour in ways that improve your symptoms.</p> <p>Many menopause symptoms are known as “non-specific” symptoms. This is because they can also be symptoms of mental health, thyroid or heart problems. It is important not to think your symptoms are “just” the menopause. You should always speak to your doctor if you are worried about your health.</p> <p>Another good thing about monitoring symptoms is that you can take information about how often you experience symptoms and how bad they are to your GP appointment. This can help the doctor decide what might be the problem.</p> <p>Websites such as <a href="https://healthandher.com">Health and Her</a> and <a href="https://www.balance-menopause.com">Balance</a> offer symptom monitoring tools that can help you track what is happening to your physical and emotional health. There are several apps you can use on your phone, too. Or you might prefer to note symptoms and how bad they are in a notebook every day.<!-- Below is The Conversation's page counter tag.

‘Girl math’ may not be smart financial advice, but it could help women feel more empowered with money

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/ylva-baeckstrom-1463175">Ylva Baeckstrom</a>, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p>If you’ve ever calculated cost per wear to justify the price of an expensive dress, or felt like you’ve made a profit after returning an ill-fitting pair of jeans, you might be an expert in <a href="https://www.standard.co.uk/news/world/girl-maths-tiktok-trend-its-basically-free-b1100504.html">“girl math”</a>. With videos about the topic going viral on social media, girl math might seem like a silly (<a href="https://www.glamourmagazine.co.uk/article/girl-math-womens-spending-taken-seriously">or even sexist</a>) trend, but it actually tells us a lot about the relationship between gender, money and emotions.</p> <p>Girl math introduces a spend classification system: purchases below a certain value, or made in cash, don’t “count”. Psychologically, this makes low-value spending feel safe and emphasises the importance of the long-term value derived from more expensive items. For example, girl math tells us that buying an expensive dress is only “worth it” if you can wear it to multiple events.</p> <p>This approach has similarities to <a href="https://www.investopedia.com/terms/m/modernportfoliotheory.asp">portfolio theory</a> – a method of choosing investments to maximise expected returns and minimise risk. By evaluating how each purchase contributes to the shopping portfolio, girl math shoppers essentially become shopping portfolio managers.</p> <h2>Money and emotions</h2> <p>People of all genders, rich or poor, feel anxious when dealing with their personal finances. Many people in the UK do not understand pensions or saving enough to <a href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/workplacepensions/articles/pensionparticipationatrecordhighbutcontributionsclusteratminimumlevels/2018-05-04">afford their retirement</a>. Without motivation to learn, people avoid dealing with money altogether. One way to find this motivation, as girl math shows, is by having an emotional and tangible connection to our finances.</p> <p>On the surface, it may seem that women are being ridiculed and encouraged to overspend by using girl math. From a different perspective, it hints at something critical: for a person to really care about something as seemingly abstract as personal finance, they need to feel that they can relate to it.</p> <p>Thinking about money in terms of the value of purchases can help create an <a href="https://www.thetimes.co.uk/article/every-time-i-use-my-card-my-phone-buzzes-and-that-stops-me-shopping-ps0fjx6nj">emotional relationship</a> to finance, making it something people want to look after.</p> <figure><iframe src="https://www.youtube.com/embed/GPzA7B6dcxc?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>The girl math we need</h2> <p>Women are a consumer force to be reckoned with, controlling <a href="https://www.forbes.com/sites/bridgetbrennan/2015/01/21/top-10-things-everyone-should-know-about-women-consumers/#7679f9d6a8b4">up to 80%</a> of consumer spending globally. The girl math trend is a demonstration of women’s mastery at applying portfolio theory to their shopping, making them investment powerhouses whose potential is overlooked by the financial services industry.</p> <p><a href="https://www.theguardian.com/world/2019/oct/28/women-paid-less-than-men-over-careers-gender-pay-gap-report">Women are disadvantaged</a> when it comes to money and finance. Women in the UK earn on average £260,000 less than men during their careers and the retirement income of men is twice as high as women’s.</p> <p>As I’ve found in <a href="https://www.routledge.com/Gender-and-Finance-Addressing-Inequality-in-the-Financial-Services-Industry/Baeckstrom/p/book/9781032055572">my research</a> on gender and finance, women have lower financial self-efficacy (belief in their own abilities) compared to men. This is not helped by women feeling patronised when seeking financial advice.</p> <p>Because the world of finance was created by men for men, its language and culture are <a href="https://www.routledge.com/Gender-and-Finance-Addressing-Inequality-in-the-Financial-Services-Industry/Baeckstrom/p/book/9781032055572">intrinsically male</a>. Only in the mid-1970s did women in the UK gain the legal right to open a bank account without a male signature and it was not until 1980 that they could apply for credit independently. With the law now more (<a href="https://www.worldbank.org/en/news/press-release/2023/03/02/pace-of-reform-toward-equal-rights-for-women-falls-to-20-year-low">but not fully</a>) gender equal, the financial services industry has failed to connect with women.</p> <p>Studies show that 49% of women are <a href="https://www.ellevest.com/magazine/disrupt-money/ellevest-financial-wellness-survey">anxious about their finances</a>. However they have not bought into patronising offers and <a href="https://www.fa-mag.com/news/gender-roles-block-female-financial-experience--ubs-says-73531.html">mansplaining by financial advisers</a>. This outdated approach suggests that it is women, rather than the malfunctioning financial system, <a href="https://www.theguardian.com/commentisfree/2020/sep/16/women-are-not-financially-illiterate-they-need-more-than-condescending-advice">who need fixing</a>.</p> <p>Women continue to feel that they do not belong to or are able to trust the world of finance. And why would women trust an industry with a <a href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/earningsandworkinghours/bulletins/genderpaygapintheuk/2019">gender pay gap</a> of up to 59% and a severe lack of women in senior positions?</p> <p>Girl math on its own isn’t necessarily good financial advice, but if it helps even a handful of women feel more empowered to manage and understand their finances, it should not be dismissed.</p> <p><!-- End of code.

Good news: midlife health is about more than a waist measurement. Here’s why

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/rob-newton-12124">Rob Newton</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>You’re not in your 20s or 30s anymore and you know regular health checks are important. So you go to your GP. During the appointment they measure your waist. They might also check your weight. Looking concerned, they recommend some lifestyle changes.</p> <p>GPs and health professionals commonly <a href="https://theconversation.com/the-body-mass-index-cant-tell-us-if-were-healthy-heres-what-we-should-use-instead-211190">measure waist circumference</a> as a vital sign for health. This is a better indicator than body mass index (BMI) of the amount of intra-abdominal fat. This is the really risky fat around and within the organs that can drive heart disease and metabolic disorders such as type 2 diabetes.</p> <p>Men are at greatly increased risk of health issues if their waist circumference is <a href="https://www.bmj.com/content/311/7017/1401">greater than 102 centimetres</a>. Women are considered to be at greater risk with a waist circumference of <a href="https://www.bmj.com/content/311/7017/1401">88 centimetres or more</a>. More than <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">two-thirds of Australian adults</a> have waist measurements that put them at an increased risk of disease. An even better indicator is waist circumference divided by height or <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease.">waist-to-height ratio</a>.</p> <p>But we know people (especially women) have a propensity to <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">gain weight around their middle during midlife</a>, which can be very hard to control. Are they doomed to ill health? It turns out that, although such measurements are important, they are not the whole story when it comes to your risk of disease and death.</p> <h2>How much is too much?</h2> <p>Having a waist circumference to height ratio larger than 0.5 is associated with greater risk of chronic disease as well as premature death and this applies in adults of any age. A healthy waist-to-height ratio is between 0.4 to 0.49. A ratio of 0.6 or more <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease">places a person at the highest risk of disease</a>.</p> <p>Some experts recommend <a href="https://www.nature.com/articles/s41574-019-0310-7">waist circumference be routinely measured in patients during health appointments</a>. This can kick off a discussion about their risk of chronic diseases and how they might address this.</p> <p>Excessive body fat and the associated health problems manifest more strongly during midlife. A range of social, personal and physiological factors come together to make it more difficult to control waist circumference as we age. Metabolism tends to slow down mainly due to decreasing muscle mass because people do <a href="https://onlinelibrary.wiley.com/doi/10.1002/jcb.25077">less vigorous physical activity, in particular resistance exercise</a>.</p> <p>For women, hormone levels begin changing in mid-life and this also <a href="https://www.tandfonline.com/doi/full/10.3109/13697137.2012.707385">stimulates increased fat levels particularly around the abdomen</a>. At the same time, this life phase (often involving job responsibilities, parenting and caring for ageing parents) is when elevated stress can lead to <a href="https://journals.lww.com/psychosomaticmedicine/abstract/2000/09000/stress_and_body_shape__stress_induced_cortisol.5.aspx">increased cortisol which causes fat gain in the abdominal region</a>.</p> <p>Midlife can also bring poorer sleep patterns. These contribute to fat gain with <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0010062">disruption to the hormones that control appetite</a>.</p> <p>Finally, your family history and genetics can <a href="https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1002695">make you predisposed to gaining more abdominal fat</a>.</p> <h2>Why the waist?</h2> <p>This intra-abdominal or visceral fat is much more metabolically active (it has a greater impact on body organs and systems) than the fat under the skin (subcutaneous fat).</p> <p>Visceral fat surrounds and infiltrates major organs such as the liver, pancreas and intestines, releasing a variety of chemicals (hormones, inflammatory signals, and fatty acids). These affect inflammation, lipid metabolism, cholesterol levels and insulin resistance, <a href="https://academic.oup.com/eurheartjsupp/article/8/suppl_B/B4/461962">contributing to the development of chronic illnesses</a>.</p> <p>The issue is particularly evident <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">during menopause</a>. In addition to the direct effects of hormone changes, <a href="https://www.sciencedirect.com/science/article/pii/S0960076013001118?via%3Dihub">declining levels of oestrogen change brain function, mood and motivation</a>. These psychological alterations can result in reduced physical activity and increased eating – often of comfort foods high in sugar and fat.</p> <p>But these outcomes are not inevitable. Diet, exercise and managing mental health can limit visceral fat gains in mid-life. And importantly, the waist circumference (and ratio to height) is just one measure of human health. There are so many other aspects of body composition, exercise and diet. These can have much larger influence on a person’s health.</p> <h2>Muscle matters</h2> <p>The quantity and quality of skeletal muscle (attached to bones to produce movement) a person has makes a <a href="https://www.nature.com/articles/nrendo.2012.49">big difference</a> to their heart, lung, metabolic, immune, neurological and mental health as well as their physical function.</p> <p>On current evidence, it is equally or more important for health and longevity to <a href="https://www.bmj.com/content/345/bmj.e7279">have</a> higher muscle mass and better cardiorespiratory (aerobic) fitness than waist circumference within the healthy range.</p> <p>So, if a person does have an excessive waist circumference, but they are also sedentary and have less muscle mass and aerobic fitness, then the recommendation would be to focus on an appropriate exercise program. The fitness deficits should be addressed as priority rather than worry about fat loss.</p> <p>Conversely, a person with low visceral fat levels is not necessarily fit and healthy and may have quite poor aerobic fitness, muscle mass, and strength. <a href="https://bjsm.bmj.com/content/45/6/504">The research evidence</a> is that these vital signs of health – how strong a person is, the quality of their diet and how well their heart, circulation and lungs are working – are more predictive of risk of disease and death than how thin or fat a person is.</p> <p>For example, a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5510687/">2017 Dutch study</a> followed overweight and obese people for 15 years and found people who were very physically active had no increased heart disease risk than “normal weight” participants.</p> <h2>Getting moving is important advice</h2> <p>Physical activity has many benefits. Exercise can counter a lot of the negative behavioural and physiological changes that are occurring during midlife including for people going through menopause.</p> <p>And regular exercise reduces the tendency to use food and drink to help manage what can be a <a href="https://journals.lww.com/acsm-msse/fulltext/2008/05000/physical_activity,_sedentary_index,_and_mental.7.aspx">quite difficult time in life</a>.</p> <p>Measuring your waist circumference and monitoring your weight remains important. If the measures exceed the values listed above, then it is certainly a good idea to make some changes.

Elephant tourism often involves cruelty – here are steps toward more humane, animal-friendly excursions

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a></em></p> <p>Suju Kali is a 50-year-old elephant in Nepal who has been carrying tourists for over 30 years. Like many elephants I encounter through my <a href="https://doi.org/10.1080/10888705.2022.2028628">research</a>, Suju Kali exhibits anxiety and can be aggressive toward strangers. She suffers from emotional trauma as a result of prolonged, commercial human contact.</p> <p>Like Suju Kali, many animals are trapped within the tourism industry. Some venues have no oversight and little concern for animal or tourist safety. Between 120,000 and 340,000 animals are used globally in a variety of wildlife tourism attractions, including <a href="https://doi.org/10.1371/journal.pone.0138939">endangered species</a> like elephants. Over a quarter of the world’s <a href="https://www.iucnredlist.org/species/7140/45818198">endangered elephants</a> reside in captivity with little oversight.</p> <p>Wildlife tourism – which involves viewing wildlife such as primates or birds in conservation areas, feeding or touching captive or “rehabilitated” wildlife in facilities, and bathing or riding animals like elephants – is <a href="https://doi.org/10.1080/14724049.2022.2156523">tricky business</a>. I know this because I am <a href="https://scholar.google.com/citations?user=YbweA2MAAAAJ&amp;hl=en">a researcher studying human relationships with elephants</a> in both tourism and conservation settings within Southeast Asia.</p> <p>These types of experiences have long been an <a href="https://kathmandupost.com/money/2021/06/17/tourism-is-nepal-s-fourth-largest-industry-by-employment-study">extremely popular and profitable</a> part of the <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002074">tourism market</a>. But now, many travel-related organizations are urging people not to participate in, or <a href="https://www.usatoday.com/story/travel/destinations/2018/04/27/animal-welfare-travelers-how-enjoy-wildlife-without-harming/544938002/">calling for an outright ban on, interactive wildlife experiences</a>.</p> <p>Tourism vendors have started marketing more “ethical options” for consumers. Some are attempting to truly improve the health and welfare of wildlife, and some are transitioning captive wildlife into touch-free, non-riding or lower-stress environments. In other places, organizations are attempting to <a href="https://www.fao.org/documents/card/es/c/b2c5dad0-b9b9-5a3d-a720-20bf3b9f0dc2/">implement standards of care</a> or create manuals that outline good practices for animal husbandry.</p> <p>This marketing, academics argue, is often simply “<a href="https://doi.org/10.1016/j.gecco.2017.11.007">greenwashing</a>,” <a href="http://dx.doi.org/10.1080/13683500.2023.2280704">applying marketing labels to make consumers feel better</a> about their choices without making any real changes. Worse, research shows that some programs marketing themselves as ethical tourism may instead be widening economic gaps and harming both humans and other species that they are meant to protect.</p> <h2>No quick fix</h2> <p>For example, rather than tourist dollars trickling down to local struggling families as intended by local governments, many tourism venues are owned by nonresidents, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">meaning the profits do not stay in the area</a>. Likewise, only a small number of residents can afford to own tourism venues, and venues do not provide employment for locals from lower income groups.</p> <p>This economic gap is especially obvious in Nepalese elephant stables: Venue owners continue to make money off elephants, while elephant caregivers continue to work 17 hours a day for about US$21 a month; tourists are led to believe they are “<a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">promoting sustainability</a>.”</p> <p>Yet, there are no easy answers, especially for elephants working in tourism. Moving them to sanctuaries is difficult because with no governmental or global welfare oversight, elephants may end up in worse conditions.</p> <p>Many kindhearted souls who want to “help” elephants know little about their biology and mental health needs, or what it takes to keep them healthy. Also, feeding large animals like Suju Kali is pricey, <a href="https://doi.org/10.3390/ani14010171">costing around $19,000 yearly</a>. So without profits from riding or other income, owners – or would-be rescuers – can’t maintain elephants. Releasing captive elephants to the jungle is not a choice – many have never learned to live in the wild, so they cannot survive on their own.</p> <h2>Hurting local people</h2> <p>Part of the problem lies with governments, as many have marketed tourism as a way to fund conservation projects. For example in Nepal, a percentage of ticket sales from elephant rides are given to community groups to use for forest preservation and support for local families.</p> <p>Increasing demand for <a href="https://www.routledge.com/Tourism-and-Animal-Ethics/Fennell/p/book/9781032431826">wildlife-based tourism</a> may increase traffic in the area and thus put pressure on local governments to further limit local people’s access to forest resources.</p> <p>This may also lead to <a href="https://www.worldanimalprotection.org/latest/news/un-world-tourism-organisation-urged-create-better-future-animals/">increased demands on local communities</a>, as was the case in Nepal. In the 1970s, the Nepalese government removed local people from their lands in what is now Chitwan National Park as part of increasing “conservation efforts” and changed the protected area’s boundaries. Indigenous “Tharu,” or people of the forest, were forced to abandon their villages and land. While some were offered access to “buffer zones” in the 1990s, many remain poor and landless today.</p> <p>In addition, more and more desirable land surrounding conservation areas in Nepal is being developed for tourist-based businesses such as hotels, restaurants and shops, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">pushing local poor people farther away</a> from central village areas and the associated tourism income.</p> <p>Some activists would like humans to simply release all wildlife back into the wild, but <a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">there are multiple issues</a> with that. Elephant habitats throughout Southeast Asia have been transformed into croplands, cities or train tracks for human use. Other problems arise from the fact that tourism elephants have <a href="https://doi.org/10.4324/9781315457413">never learned</a> how to be elephants in their natural elements, as they were <a href="https://www.pugetsound.edu/sites/default/files/file/8342_Journal%20of%20Tourism%20%282009%29_0.pdf">separated from their herds</a> at an early age.</p> <p>So tourism may be vital to providing food, care and shelter to captive elephants for the rest of their lives and providing jobs for those who really need them. Because elephants can live beyond 60 years, this can be a large commitment.</p> <h2>How to be an ethical tourist</h2> <p>To protect elephants, tourists should check out reviews and photos from any venue they want to visit, and look for clues that animal welfare might be impacted, such as tourists allowed to feed, hold or ride captive wildlife animals. Look for healthy animals, which means doing research on what “healthy” animals of that species should look like.</p> <p>If a venue lists no-touch demonstrations – “unnatural” behaviors that don’t mimic what an elephant might do of their own accord, such as sitting on a ball or riding a bike, or other performances – remember that the behind-the-scenes training used to achieve these behaviors can be <a href="https://doi.org/10.21832/9781845415051-014">violent, traumatic or coercive</a>.</p> <p>Another way to help people and elephant is to to use small, local companies to book your adventures in your area of interest, rather than paying large, international tourism agencies. Look for locally owned hotels, and wait to book excursions until you arrive so you can use local service providers. Book homestay programs and attend cultural events led by community members; talk to tourists and locals you meet in the target town to get their opinions, and use local guides who provide wildlife viewing opportunities <a href="https://nepaldynamicecotours.com/">while maintaining distance from animals</a>.</p> <p>Or tourists can ask to visit <a href="https://www.americanhumane.org/press-release/global-humane-launches-humane-tourism-certification-program/">venues that are certified</a> by international humane animal organizations and that <a href="https://www.su4e.org/">do not allow contact</a> with wildlife. Or they can opt for guided hikes, canoe or kayak experiences, and other environmentally friendly options.</p> <p>While these suggestions will not guarantee that your excursion is animal-friendly, they will help decrease your impact on wildlife, support local families and encourage venues to stop using elephants as entertainment. Those are good first steps.<!-- Below is The Conversation's page counter tag.

Drugs like Ozempic won’t ‘cure’ obesity but they might make us more fat-phobic

<p><em><a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Many have <a href="https://www.economist.com/leaders/2023/03/02/new-drugs-could-spell-an-end-to-the-worlds-obesity-epidemic">declared</a> drugs like Ozempic could “end obesity” by reducing the appetite and waistlines of millions of people around the world.</p> <p>When we look past the hype, this isn’t just untrue – it can also be harmful. The focus on weight, as opposed to health, is a feature of <a href="https://www.sciencedirect.com/science/article/abs/pii/S0277539521001217">diet culture</a>. This frames the pursuit of thinness as more important than other aspects of physical and cultural wellbeing.</p> <p>The Ozempic buzz isn’t just rooted in health and medicine but plays into ideas of <a href="https://butterfly.org.au/weight-bias-fatphobia-diet-culture/#:%7E:text=Weight%20bias%2C%20sometimes%20also%20called,or%20being%20around%20fat%20people.">fat stigma and fat phobia</a>. This can perpetuate fears of fatness and fat people, and the behaviours that <a href="https://link.springer.com/article/10.1186/S12916-018-1116-5">harm people who live in larger bodies</a>.</p> <h2>Not the first ‘miracle’ weight-loss drug</h2> <p>This isn’t the first time we have heard that weight-loss drugs will change the world. Ozempic and <a href="https://www.ncbi.nlm.nih.gov/books/NBK551568/">its family</a> of GLP-1-mimicking drugs are the <a href="https://theconversation.com/ozempic-is-in-the-spotlight-but-its-just-the-latest-in-a-long-and-strange-history-of-weight-loss-drugs-209324">latest in a long line of weight loss drugs</a>. Each looked promising at the time. But none have lived up to the hype in the long term. Some have even been withdrawn from sale due to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5126837/">severe side effects</a>.</p> <p>Science does improve <a href="https://www.thelancet.com/journals/lanmic/article/PIIS2666-5247(20)30028-8/fulltext">incrementally</a>, but diet culture also keeps us on a cycle of hope for the next <a href="https://sahrc.org/2022/04/diet-culture-a-brief-history/">miracle cure</a>. So drugs like Ozempic might not deliver the results individuals expect, continuing the cycle of hope and shame.</p> <h2>Ozempic doesn’t work the same for everyone</h2> <p>When we talk about the results of studies using Ozempic, we often <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3719041/">focus on the average</a> (also known as the mean) results or the maximum (or peak) results. So, studies might <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">show</a> those using the drug lost an average of 10.9% of their body weight, but some lost more than 20% and others less than 5%</p> <p>What we don’t talk about as much is that responses are variable. Some people are “<a href="https://www.sciencedirect.com/science/article/pii/S2212877820301769">non-responders</a>”. This means not everyone loses as much weight as the average, and some don’t lose weight at all. For some people, the side-effects will outweigh the benefits.</p> <p>When people are on drugs like Ozempic, their blood sugar is better controlled by enhancing the release of insulin and reducing the levels of another hormone called glucagon.</p> <p>But there is greater variability in the amount of <a href="https://www.sciencedirect.com/science/article/pii/S2212877820301769#bib88">weight lost</a> than the variability in blood sugar control. It isn’t clear why, but is likely due to differences in genetics and lifestyles, and weight being more complex to regulate.</p> <h2>Treatment needs to be ongoing. What will this mean?</h2> <p>When weight-loss drugs do work, they are only effective while they’re being taken. This means that to keep the weight off people need to keep taking them long term. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9542252/">One study found</a> an average weight loss of more than 17% after a year on Ozempic became an average net weight loss of 5.6% more than two years after stopping treatment.</p> <p>Short-term side effects of drugs like Ozempic include dizziness, nausea, vomiting and other gastrointestinal upsets. But because these are new drugs, we simply don’t have data to tell us if side effects will increase as people take them for longer periods.</p> <p>Nor do we know if <a href="https://www.medicalnewstoday.com/articles/why-weight-loss-drugs-stop-working-how-to-break-past-ozempic-plateau#:%7E:text=A%20lifetime%20commitment%20to%20Ozempic&amp;text=By%20these%20standards%2C%20such%20drugs,long%2Dterm%20risk%20is%20unknown.">effectiveness will be reduced</a> in the long term. This is called <a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/drug-tolerance#:%7E:text=A%20condition%20that%20occurs%20when,or%20different%20medicine%20is%20needed.">drug tolerance</a> and is documented for other long-term treatments such as antidepressants and chemotherapies.</p> <h2>Biology is only part of the story</h2> <p>For some people, using GLP-1-mimicking drugs like Ozempic will be validating and empowering. They will feel like their biology has been “normalised” in the same way that blood pressure or cholesterol medication can return people to the “normal” range of measures.</p> <p>But biologically, obesity <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7202176/#:%7E:text=Obesity%20behaves%20as%20complex%20polygenic,about%2080%25%20(3).">isn’t solely about GLP-1 activity</a> with <a href="https://www.worldobesity.org/what-we-do/our-policy-priorities/the-roots-of-obesity">many other</a> hormones, physical activity, and even our gut microbes involved.</p> <p>Overall, <a href="https://www.ncbi.nlm.nih.gov/books/NBK278977/">obesity is complex and multifaceted</a>. Obesity isn’t just driven by personal biology and choice; it has social, cultural, political, environmental and economic determinants.</p> <h2>A weight-centred approach misses the rest of the story</h2> <p>The weight-centred approach <a href="https://butterfly.org.au/body-image/health-not-weight/#:%7E:text=Health%20and%20wellbeing%20are%20multi,on%20their%20size%20or%20appearance.">suggests that leading with thinness means health will follow</a>. But changing appetite is only part of the story when it comes to health.</p> <p>Obesity often <a href="https://www.sciencedirect.com/science/article/pii/S2667368123000335#:%7E:text=Obesity%20related%20malnutrition%20can%20also,%5D%2C%20%5B7%5D%5D.">co-exists with malnutrition</a>. We try to separate the effects in research using statistics, but focusing on the benefits of weight-loss drugs without addressing the underlying malnutrition means we aren’t likely to see the <a href="https://www.wsj.com/articles/ozempic-diet-exercise-healthy-43eee86c">improved health outcomes in everyone who loses weight</a>.</p> <h2>Obesity isn’t an issue detached from people</h2> <p>Even when it is well-intentioned, the rhetoric around the joy of “ending the obesity epidemic” can <a href="https://theconversation.com/ozempic-the-miracle-drug-and-the-harmful-idea-of-a-future-without-fat-211661">harm people</a>. Obesity doesn’t occur in isolation. It is people who are obese. And the celebration and hype of these weight-loss drugs can reinforce harmful fat stigma.</p> <p>The framing of these drugs as a “cure” exacerbates the binary view of thin versus fat, and healthy versus unhealthy. These are not binary outcomes that are good or bad. Weight and health exist on a spectrum.</p> <p>Ironically, while fat people are told they need to lose weight for their health, they are also <a href="https://www.dailytelegraph.com.au/news/nsw/ozempic-shame-why-users-are-embarrassed-to-admit-using-weight-loss-wonder-drug/news-story/ee52a819c69459afe6576d25988f9bd6">shamed for “cheating” or taking shortcuts</a> by using medication.</p> <h2>Drugs are tools, not silver bullets</h2> <p>The creation of these drugs is a start, but they remain expensive, and the hype has been followed by <a href="https://www.tga.gov.au/safety/shortages/information-about-major-medicine-shortages/about-ozempic-semaglutide-shortage-2022-and-2023#:%7E:text=Consumer%20Medicine%20Information%20.-,Why%20the%20Ozempic%20shortage%20happened,label%20prescribing%20for%20weight%20loss.">shortages</a>. Ultimately, complex challenges aren’t addressed with simple solutions. This is particularly true when people are involved, and even more so when there isn’t even an agreement on what the challenge is.</p> <p>Many organisations and individuals see obesity is a disease and believe this framing helps people to seek treatment.</p> <p>Others think it’s unnecessary to attach medical labels to body types and <a href="https://www.forbes.com/sites/geoffreykabat/2013/07/09/why-labeling-obesity-as-a-disease-is-a-big-mistake/?sh=5ca95cc2103b">argue</a> it confuses risk factors (things that are linked to increased risk of illness) with illness itself.</p> <p>Regardless, two things will always remain true. Drugs can only ever be tools, and those tools need to be applied in a context. To use these tools ethically, we need to remain mindful of who this application harms along the way.</p> <hr /> <p><em>Read the other articles in The Conversation’s <a href="https://theconversation.com/au/topics/ozempic-series-154673">Ozempic series</a> here.<!-- Below is The Conversation's page counter tag.

One such region is the Upper Hunter Valley, the subject of our <a href="https://www.mdpi.com/2225-1154/12/4/49">new research</a>.</p> <p>We identified two climate drivers – the <a href="http://www.bom.gov.au/climate/about/?bookmark=enso">El Niño Southern Oscillation</a> and <a href="http://www.bom.gov.au/climate/about/?bookmark=iod">Indian Ocean Dipole</a>) – that became influential during this drought. In addition, the waning influence of a third climate driver, the <a href="http://www.bom.gov.au/climate/about/?bookmark=sam">Southern Annular Mode</a>), would typically bring rain to the east coast. However, this rain did not reach the Upper Hunter.</p> <p>Flash droughts are set to get more common as the world heats up. This year, a flash drought developed over western and central Victoria over just two months. While heavy rain this month in Melbourne ended the drought there, it continues in the west.</p> <h2>What makes a flash drought different?</h2> <p>Flash droughts differ from more slowly developing droughts. The latter result from extended drops in rainfall, such as the <a href="http://www.bom.gov.au/climate/drought/">drought affecting</a> parts of southwest Western Australia due to the much shortened winter wet season last year.</p> <p>Flash droughts develop when sudden large drops in rainfall coincide with above-average temperatures. They mostly occur in summer and autumn, as was the case for Asia and Europe in 2022. That year saw flash droughts appear across the northern hemisphere, such as the megadrought affecting China’s <a href="https://iopscience.iop.org/article/10.1088/1748-9326/acfe21">Yangtze river basin</a> and <a href="https://www.sciencedirect.com/science/article/pii/S2352340923000264?via%3Dihub">Spain</a>.</p> <p>The flash drought devastating the Upper Hunter from May to October 2023 developed despite the region being drought-free just one month earlier. At that stage, almost nowhere in NSW showed any sign of an impending drought.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=276&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=276&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=276&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=347&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=347&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=347&amp;fit=crop&amp;dpr=3 2262w" alt="Maps of drought conditions in NSW in April 2023 compared to the next six months" /><figcaption><span class="caption">NSW Department of Primary Industries’ combined drought indicator in April 2023 (a) and combined drought indicator for May–October 2023 (b) show how rapidly a flash drought developed in the Upper Hunter region.</span> <span class="attribution"><span class="source">Milton Speer et al 2024, using NSW Department of Primary Industries' data</span></span></figcaption></figure> <p>The flash drought greatly affected agricultural production in the Upper Hunter region, due to the region’s reliance on water from rivers.

The much lower rainfall continued until November in the Upper Hunter. Over this same period, mean maximum temperatures in the region were the highest on record, increasing the loss of moisture through evapotranspiration. The result was a flash drought. While flash droughts occurred in other parts of south-east Australia, we focused on the Upper Hunter as it remained in drought the longest.</p> <h2>What were the climate drivers of this drought?</h2> <p>We used machine-learning techniques to identify the key climate drivers of the drought.</p> <p>We found the dominant driver of the flash drought was global warming, modulated by the phases of the three major climate drivers in our region, the El Niño Southern Oscillation, Indian Ocean Dipole and the Southern Annular Mode.</p> <p>From 2020 to 2022, the first two drivers became favourable for rain in the Upper Hunter in late winter through spring, before changing phase to one supporting drought over south-east Australia. Meanwhile, the Southern Annular Mode remained mostly positive, meaning rain-bearing westerly winds and weather fronts had moved to middle and higher latitudes of the southern hemisphere, away from Australia’s south-east coast.</p> <p>Combined, the impact of global warming with the three climate drivers made rainfall much more variable. The net result was an atmospheric environment highly conducive to a flash drought appearing anywhere in south-east Australia.</p> <figure class="align-right zoomable"><a href="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=464&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=464&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=464&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=583&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=583&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=583&amp;fit=crop&amp;dpr=3 2262w" alt="Map of Upper Hunter region showing drought indicators in December 2023" /></a><figcaption><span class="caption">Intense drought conditions continued in the Upper Hunter in December 2023.</span> <span class="attribution"><span class="source">Milton Speer et al 2024</span></span></figcaption></figure> <h2>Victoria, too, fits the global warming pattern</h2> <p>As for the flash drought that developed in early 2024 over western and central Victoria, including Melbourne, it continues in parts of <a href="http://www.bom.gov.au/climate/drought/#msdynttrid=_ytsVsw1a3IFZ7xGCnQz8mw1Gum_n_0JUdQyt2hUVCo">western Victoria</a>.

Home and Away star calls for more diversity

<p><em>Home and Away </em>star Ray Meagher has spoken out about the iconic soap changing direction from its original premise and how he wants better LGBTQ+ representation on the show. </p> <p>Meagher, who has played Alf Stewart on the show since 1988 and is signed on until at least 2027, shared his thoughts on the show's creative direction. </p> <p>The soap, which has explored every possible plot line with cults, abductions, car and motorcycle accidents, health scares, and more, started to go on a different journey following the introduction of the River boys in 2011, with the storyline now focusing more on crimes. </p> <p>Meagher criticised network execs for letting the soap stray from its premise of a seaside community and its original Fletcher family taking in foster children.</p> <p>“There is still penchant for a River Boy,”  he said in an interview with <em>TV Tonight</em>. </p> <p>“I mean, that was just a great period. But was it Summer Bay? Hmmm…. in my humble opinion, not to that extent,” Meagher added. </p> <p>He also said that there was nothing wrong with the storylines or the focus on "sex, drugs and rock and roll" but believes that the change of pace "came in too big of a dose," and made the show completely different from its original plot. </p> <p>Meagher also said that it's about time the show had better LGBTQ+ representation, after the show was previously criticised for lack of sustained LGBTQIA+ characters</p> <p>“It’d be nice to have a nice gay character come into the Bay. That would be good,” he said.</p> <p>“However, how many of them do we have in Summer Bay? There would definitely be a percentage, whether they’re above the ground or underground still in a town like the Bay."</p> <p>“The one thing that I have a bit of a problem with is sometimes when you realise there’s a representative hole when people tend to think, ‘Oh, jeez, we’ve ignored that area,’ and then there’s a wash of it. And you think ‘No community looks like that," he added.</p> <p><em>Image: Seven</em></p>

Two more infant deaths at Queensland hospital spark coroner's investigation

<p>In the wake of a recent healthcare scandal involving infant fatalities at a Queensland hospital, the state coroner is now delving into two more heartbreaking cases at the same facility, as <a href="https://www.abc.net.au/news/2024-03-12/coroner-investigating-more-baby-deaths-at-mackay-base-hospital/103573248" target="_blank" rel="noopener">reported by the ABC</a>. This development has reignited concerns about the safety and quality of care provided to expectant mothers and newborns at Mackay Base Hospital.</p> <p>The stories of Chloe Stanley and Jenna McGregor echo a disturbing pattern of maternal distress, dismissal of concerns and tragic outcomes. Stanley's baby girl, Everlee, tragically passed away in her arms just seven days after birth in May 2023, while McGregor lost her son, Hugo, five days after his birth, two months prior. Both infants succumbed to hypoxic-ischaemic encephalopathy, a condition stemming from oxygen or blood flow deprivation during birth.</p> <p>Stanley's harrowing experience sheds light on a systemic issue of young mothers feeling marginalised and ignored by healthcare professionals. At just 19 years old, Stanley expressed her belief that she was being "judged" for her ago, leading to dismissal of her concerns about her baby's well-being, ultimately resulting in devastating consequences. McGregor's ordeal parallels Stanley's, underscoring a troubling lack of responsiveness to maternal distress and the urgent need for systemic reforms.</p> <p>These recent tragedies evoke haunting memories of <a href="https://www.abc.net.au/news/2022-09-30/mackay-hospital-health-service-babies-obstetrics-review/101411172" target="_blank" rel="noopener">a similar case a decade ago</a>, involving the loss of Jessica Beazley's newborn son, Nathan. Like Stanley and McGregor, <a href="https://www.abc.net.au/news/2022-09-30/mackay-base-hospital-obstetrics-harming-mother-and-baby/101485862" target="_blank" rel="noopener">Beazley's concerns </a>appear to have  been disregarded, leading to irreversible harm. An investigation into Mackay Base Hospital's obstetrics and gynaecology service in 2022 revealed a disturbing pattern of inadequate care contributing to infant deaths and maternal suffering, prompting calls for comprehensive reforms.</p> <p>The review uncovered 122 recommendations aimed at improving communication, culture and empathy within the hospital's maternity care system. However, despite assurances of progress, Stanley and McGregor's experiences suggest that critical reforms have yet to be fully implemented, leaving expectant mothers vulnerable to similar tragedies.</p> <p>The Root Cause Analysis conducted by the Mackay Hospital and Health Service (MHHS) following McGregor's loss identified several systemic deficiencies, including delays in care escalation, poor collaboration and communication breakdowns. These findings underscore the urgent need for sustained efforts to address systemic failures and ensure the safety of expectant mothers and their babies.</p> <p>Stanley's and McGregor's accounts of feeling dismissed and unheard by healthcare providers highlight a pervasive culture of neglect and complacency that must be addressed. </p> <p>In response to these tragedies, health authorities have pledged to bolster obstetric care and enhance staff training and empathy initiatives. </p> <p>As the Queensland coroner investigates these heartbreaking cases, it is imperative that lessons are learned, and systemic reforms are swiftly implemented to prevent further loss of innocent lives.</p> <p>Expectant mothers like Chloe Stanley and Jenna McGregor deserve nothing less than the highest standard of care and compassion throughout their pregnancy and childbirth journey.</p> <p><em>Images: Mackay Base Hospital \ Getty Images file photo</em> </p>

The US just returned to the Moon after more than 50 years. How big a deal is it, really?

<p><em><a href="https://theconversation.com/profiles/david-flannery-3906">David Flannery</a>, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a></em></p> <p>In the few short years since the COVID pandemic changed our world, China, Japan and India have all successfully landed on the Moon.</p> <p>Many more robotic missions have flown past the Moon, entered lunar orbit, or crashed into it in the past five years. This includes <a href="https://www.planetary.org/space-missions/kplo">spacecraft developed by South Korea</a>, <a href="https://english.alarabiya.net/News/gulf/2023/04/27/Dubai-s-ruler-announces-new-moon-mission-after-UAE-s-Rashid-Rover-lunar-crash-">the United Arab Emirates</a>, and an <a href="https://www.spaceil.com/">Israeli not-for-profit organisation</a>.</p> <p>Late last week, the American company <a href="https://www.intuitivemachines.com/">Intuitive Machines</a>, in collaboration with NASA, celebrated “America’s return to the Moon” with a successful landing of its Odysseus spacecraft.</p> <p>Recent <a href="https://theconversation.com/change-5-china-launches-sample-return-mission-to-the-moon-is-it-winning-the-new-space-race-150665">Chinese-built sample return missions</a> are far more complex than this project. And didn’t NASA ferry a dozen humans to the Moon back when microwaves were cutting-edge technology? So what is different about this mission developed by a US company?</p> <h2>Back to the Moon</h2> <p>The recent Odysseus landing stands out for two reasons. For starters, this is the first time a US-built spacecraft has landed – not crashed – on the Moon for over 50 years.</p> <p>Secondly, and far more significantly, this is the first time a private company has pulled off a successful delivery of cargo to the Moon’s surface.</p> <p>NASA has lately focused on destinations beyond the Earth–Moon system, including Mars. But with its <a href="https://www.nasa.gov/commercial-lunar-payload-services/">Commercial Lunar Payload Services</a> (CLPS) program, it has also funded US private industry to develop Moon landing concepts, hoping to reduce the delivery costs of lunar payloads and allow NASA engineers to focus on other challenges.</p> <p>Working with NASA, Intuitive Machines selected a <a href="https://en.wikipedia.org/wiki/Malapert_(crater)">landing site</a> about 300 kilometres from the lunar south pole. Among other challenges, landing here requires entering a polar orbit around the Moon, which consumes additional fuel.</p> <p>At this latitude, the land is heavily cratered and dotted with long shadows. This makes it challenging for autonomous landing systems to find a safe spot for a touchdown.</p> <p>NASA spent about US$118 million (A$180 million) to land six scientific <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/About_Payload_Systems">payloads</a> on Odysseus. This is relatively cheap. Using low-cost lunar landers, NASA will have an efficient way to test new space hardware that may then be flown on other Moon missions or farther afield.</p> <h2>Ten minutes of silence</h2> <p>One of the technology tests on the Odysseus lander, NASA’s <a href="https://www.nasa.gov/directorates/stmd/impact-story-navigation-doppler-lidar/">Navigation Doppler Lidar experiment</a> or NDL, appears to have proved crucial to the lander’s success.</p> <p>As the lander neared the surface, the company realised its navigation systems had a problem. NASA’s NDL experiment is serendipitously designed to test precision landing techniques for future missions. It seems that at the last second, engineers bodged together a solution that involved feeding necessary data from NDL to the lander.</p> <p>Ten minutes of silence followed before a <a href="https://twitter.com/Int_Machines/status/1760838333851148442">weak signal was detected</a> from Odysseus. Applause thundered through the mission control room. NASA’s administrator released a video congratulating everyone for returning America to the Moon.</p> <p>It has since become clear the lander is not oriented perfectly upright. The solar panels are generating sufficient power and the team is slowly receiving the first images from the surface.</p> <p>However, it’s likely Odysseus <a href="https://www.universetoday.com/165864/odysseus-moon-lander-is-tipped-over-but-still-sending-data/">partially toppled over</a> upon landing. Fortunately, at the time of writing, it seems most of the science payload may yet be deployed as it’s on the side of the lander facing upwards. The unlucky payload element facing downwards <a href="https://edition.cnn.com/2024/02/23/world/odysseus-lunar-landing-sideways-scn/index.html">is a privately contributed artwork</a> connected <a href="https://edition.cnn.com/2024/02/22/style/jeff-koons-moon-phases-odysseus-landing/index.html">to NFTs</a>.</p> <p>The lander is now likely to survive for at least a week before the Sun sets on the landing site and a dark, frigid lunar night turns it into another museum piece of human technology frozen in the lunar <a href="https://www.britannica.com/science/regolith">regolith</a>.</p> <h2>Win some, lose some</h2> <p>NASA’s commercial approach to stimulating low-cost payload services all but guarantees some failures. But eventually NASA hopes that several commercial launch and landing providers will emerge from the program, along with a few learning experiences.</p> <p>The know-how accumulated at organisations operating hardware in space is at least as important as the development of the hardware itself.</p> <p>The market for commercial lunar payloads remains unclear. Possibly, once the novelty wears off and brands are no longer able to generate buzz by, for example, <a href="https://www.columbia.com/omni-heat-infinity/moon-mission/">sending a piece of outdoor clothing to the Moon</a>, this source of funding may dwindle.</p> <p>However, just as today, civil space agencies and taxpayers will continue to fund space exploration to address shared science goals.</p> <p> </p> <p>Ideally, commercial providers will offer NASA an efficient method for testing key technologies needed for its schedule of upcoming scientific robotic missions, as well as <a href="https://www.nasa.gov/specials/artemis/">human spaceflight in the Artemis program</a>. Australia would also have the opportunity to test hardware at a reduced price.</p> <p>It’s worth noting that US budgetary issues, <a href="https://spacenews.com/nasa-warns-of-very-problematic-space-technology-budget-cuts/">funding cuts</a> and <a href="https://www.jpl.nasa.gov/news/jpl-workforce-update">subsequent lay-offs</a> do threaten these ambitions.</p> <p>Meanwhile, in Australia, we may have nothing to launch anyway. We continue to spend less <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_departments/Parliamentary_Library/Budget/reviews/2023-24/ScienceResearch">than the OECD average on scientific research</a>, and only a few Australian universities – who traditionally lead such efforts – <a href="https://business.gov.au/grants-and-programs/moon-to-mars-initiative-demonstrator-mission-grants/grant-recipients">have received funding</a> provided by the Australian Space Agency.</p> <p>If we do support planetary science and space exploration in the future, Australians will need to decide if we want to allocate our limited resources, competing with NASA and US private industry, to supply launch, landing and robotic services to the global space industry.</p> <p>Alternatively, we could leverage these lower-cost payload providers to develop our own scientific space program, and locally developed space technologies associated with benefits to the knowledge economy, education and national security.<!-- Below is The Conversation's page counter tag.

Yes, it’s getting more humid in summer. Here’s why

<p><em><a href="https://theconversation.com/profiles/steven-sherwood-272">Steven Sherwood</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Has Sydney felt more like Cairns lately? You’re not imagining it – millions of Australians up and down the east coast have sweltered through exceptionally high humidity in recent weeks.</p> <p>It’s due to normal weather patterns combined with a boost from global warming. Right now, the temperature of the sea surface is <a href="http://www.bom.gov.au/products/IDYOC052.Aus.SSTAnomaly.shtml">1–3°C above normal</a> for this time of year up and down the east coast. It’s particularly hot around the Queensland-New South Wales border and Tasmania’s east coast.</p> <p>When we have high ocean temperatures, we get more water evaporating. This is taken up by the air, which can hold more moisture when the air is hotter. This moist air is then carried to us by winds, and the sweating begins.</p> <h2>Where does humidity come from?</h2> <p>Humidity is just gaseous water held in the air after evaporating from liquid water or ice. It is called a vapour because it condenses into rain — the more humid, the more likely rain is.</p> <p>Higher humidity makes us feel hotter in warm weather, and slows the drying of laundry on a clothesline or of plants in the garden.</p> <p>How do we measure it? Two common ways are the “dew point” and “relative humidity”.</p> <p>At any given air temperature, there’s a limit to how much vapour the air will retain. Any vapour above this limit will just condense out. But the limit roughly doubles with every 10°C of warming; the dew point is the temperature where the vapour would hit the limit. The less vapour there is in the air, the colder the dew point.</p> <p>Relative humidity is the ratio of how much vapour the air has compared to the maximum it would retain.</p> <p>If you’re in Tasmania and see that relative humidity is at 100%, you might be confused. But this measure essentially tracks how “full” the air is. At 100% relative humidity, the dew point matches the actual temperature and no more vapour can be added. If the dew point is 10°C below the actual temperature, relative humidity is about 50%.</p> <p>How do we measure it? The dew point can be measured directly using a chilled mirror and a laser to detect condensation. More often it’s calculated from measurements of relative humidity and temperature.</p> <p>Relative humidity determines whether material exposed to the air will moisten or dry out. That’s why relative-humidity sensors use cheap water-absorbing materials (early ones used a strand of human hair!).</p> <h2>What does a changing climate mean for humidity?</h2> <p>The world’s higher ocean temperatures are unambiguously attributable to global warming, largely from the greenhouse gases we have added by burning fossil fuels. To date, more than 90% of all the extra heat thereby trapped has gone into the oceans.</p> <p>The amount of water vapour over the oceans has increased by roughly 5% since the industrial era began, in lockstep with global warming.</p> <p>Global warming will continue until we stop it. That means the atmosphere will keep getting more humid.</p> <p>If the world manages to keep global warming below 2°C, we should avoid the worst health outcomes from more humidity. But even then, we would expect up to another 5% increase in peak water vapour.</p> <p>Right now, we are seeing higher-than-normal temperatures in most of our surrounding oceans, with only a few exceptions. The areas hit hardest by rising humidity are mostly those that are already humid, like Queensland and the Northern Territory.</p> <p>Although peak dew points are rising, you may be confused to hear average relative humidity is actually <a href="https://www.pnas.org/doi/full/10.1073/pnas.1722312115">falling over land</a>. That’s because the land is warming so fast the average dew points aren’t quite keeping up with temperature, lowering the ratio.</p> <p>That means, alas, that Australia faces a double whammy: increasing water stress and bushfire risk as well as sweatier summers.</p> <h2>Humidity can be very dangerous</h2> <p>Our natural cooling system in hot weather is evaporation of sweat. Sweat forms on your skin, and the air evaporates it, taking the heat with it.</p> <p>But this only works to a point. When the dew point is higher, our self-cooling methods get less and less effective. How important this is depends on how hot you feel. On a moderate but muggy day, you might feel fine until you need to climb four flights of stairs and end up sweaty and exhausted. On a hotter but less muggy day you’d feel the heat at the outset, but would more easily handle the stairs.</p> <p>The Bureau of Meteorology uses something called “<a href="https://media.bom.gov.au/social/blog/1153/apparent-feels-like-temperature/">apparent temperature</a>” to capture the combined effect of temperature and humidity, although this assumes you’re not exerting yourself.</p> <p>How you feel with more exertion can be captured by other measures, such as the “wet bulb globe temperature” now being used at sporting events such as the Australian Open.</p> <p>The Bureau has recently begun providing <a href="http://www.bom.gov.au/places/nsw/sydney/forecast/detailed/">humidity and apparent temperature forecasts</a> as a beta product, which is great for activity planning.</p> <p>This type of information will become more important as the heat builds. As humidity increases during peak humid heat episodes, it makes heat stress worse and moves us toward our body’s physical limits.</p> <p><a href="https://www.pnas.org/doi/10.1073/pnas.2316003120">Recent research</a> has shown the combination of humidity and heat could make parts of the planet unlivable if Paris Agreement targets are not met, beginning in India and spreading elsewhere in the tropics – including the Top End of Australia.</p> <p>We need to prepare now for increasing heat, while doing everything we can to stop the routine burning of fossil fuels as soon as possible to maintain a margin of safety for humanity.<!-- Below is The Conversation's page counter tag.

More than a third of people with dementia don’t know they have it – what to do if you suspect your partner has the condition

<p><em><a href="https://theconversation.com/profiles/kate-irving-1493654">Kate Irving</a>, <a href="https://theconversation.com/institutions/dublin-city-university-1528">Dublin City University</a></em></p> <p>Around <a href="https://www.bbc.co.uk/news/uk-england-67613465">36% of people</a> in England with dementia are unaware they have the condition, according to a new report from the Dementia Commission.</p> <p><a href="https://chamberuk.com/wp-content/uploads/2023/12/231127-Dementia-Commission-Report-Embargoed.pdf">The report</a> suggests things health and care professionals can do to improve spotting early signs of dementia. But what can you do if you think your partner has the condition? And how can you broach the topic with them?</p> <p>If you are worried about your partner having dementia, here are some useful things to know.</p> <p>Dementia is a term for a range of diseases (for example, Alzheimer’s) which develop over time (months and years) and cause problems with memory and reasoning, communication, changes in personality and a reduction in a person’s ability to carry out daily activities, such as shopping, washing, paying bills or cooking.</p> <p>Dementia can present very differently in each person, so it’s about knowing what’s normal for your loved one. A person who has always been conscientious and organised starting to unravel is very different from a scatterbrained person just being slightly more scatterbrained.</p> <p>Grief and stress can affect memory yet not be the start of dementia. But they can also mask the start of dementia: we call this “diagnostic over-shadowing”.</p> <p>There are also age-related changes to cognition. For example, we take longer to learn when we get older. But a one-off event – no matter how dramatic – is not necessarily dementia. It’s about looking for a pattern of decline.</p> <p>If you see these changes happen in a short space of time (weeks or days) it is unlikely to be dementia and could be something more serious. This requires urgent investigation by a doctor.</p> <h2>Greatest fear</h2> <p>Dementia is one of the greatest fears of our age. The horror of perceived loss of self can cause people to avoid discussing the issue, discussing it in an unhelpful way (such as criticising or inadvertently humiliating) or discussing it with other relatives, but not the person they are noticing changes in.</p> <p>Over time, this can cause a lack of trust to develop. Discussing memory problems openly with the person at the point of a memory failure or if they raise the concern is best. Of course, it takes courage and makes us face our own vulnerability.</p> <p>Sometimes the person will be in denial or lack insight into the memory problems (this can be a symptom of dementia, but isn’t always). If someone raises a concern about their memory issues, I would urge you not to minimise this, as it probably took courage to admit their concerns.</p> <p>I heard a relative say to my mother: “Oh, you left the pot on the stove. I lost the car in the multistory the other day.” My mother had dementia – the relative did not.</p> <p>If they are adamant that they do not have concerns, this is harder to deal with. One approach is to say: “I know you are not concerned, but I am concerned and I wonder if you would see a doctor to ease my worries?”</p> <p>Also explaining that memory problems can at least to some extent have reversible causes means a visit to the doctor to at least rule these out is an important step. It may also be encouraging to say to the person: “If there is something with your memory that will get worse over time, would you want to know?” (Most people <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2408568/">answer yes</a> to this).</p> <h2>Seeing a GP</h2> <p>If your partner agrees to visit a GP, it is helpful to prepare by filling in a diary for a week with the kind of memory (or other) problems experienced, what was happening at the time and the effect of the memory failure. This can be shared with a GP to help them to understand the issues.</p> <p>When people hear even the suggestion of the word dementia, they are faced with the uncertainties of what will become of them, of what they will lose, what they can keep up and where they will end up. These uncertainties are often shared with family members. But research shows that positive aspects of timely diagnosis <a href="https://www.scie.org.uk/dementia/symptoms/diagnosis/early-diagnosis.asp">outweigh fears</a> over time.</p> <p>At the same time, there are often ongoing stresses to do with memory impairments or confusion. With these stresses, everyday life can be troublesome, family relationships can suffer, and people can find it difficult to be supportive of each other.</p> <p>Being honest and open is the best policy. Stating that we are in this together, I want to help, let’s meet whatever happens head on, can help. If a person becomes resistant, it may be there is another family member who might better assist the person.<!-- Below is The Conversation's page counter tag.

"Proud to pay more": The billionaires who want to pay more tax

<p>Over 250 millionaires and billionaires have issued an <a href="https://proudtopaymore.org/" target="_blank" rel="noopener">open letter</a> to global leaders encouraging them to implement wealth taxes to combat the cost-of-living crisis. </p> <p>This comes just as a report by the <a href="https://www.oversixty.com.au/finance/money-banking/shocking-amount-australia-s-richest-people-earn-per-hour" target="_blank" rel="noopener">Oxfam Charity</a> revealed that the global wealth of billionaires have only grown in the last three years despite inflation. </p> <p>The open letter, signed by super-rich individuals from 17 countries, includes signatories like Abigail Disney, the grand-niece of Walt Disney, <em>Succession </em>actor Brian Cox, and American philanthropist and Rockefeller family heir Valerie Rockefeller.</p> <p>They said that they would be "proud to pay more taxes" in order to address the  inequality.</p> <p>"Elected leaders must tax us, the super rich,"  the letter read. </p> <p>"This will not fundamentally alter our standard of living, nor deprive our children, nor harm our nations' economic growth.</p> <p>"But it will turn extreme and unproductive private wealth into an investment for our common democratic future."</p> <p>Austrian heir Marlene Engelhorn is also among the voices demanding that they pay more in taxes.</p> <p>"I've inherited a fortune and therefore power, without having done anything for it. And the state doesn't even want taxes on it,"  Engelhorn, who inherited millions from her family who founded chemical giant BASF, said.</p> <p>The letter was released just as global leaders gather in Davos, Switzerland for the World Economic Forum.</p> <p>Abigail Disney, whose net-worth is measured at more than $100 million, said that lawmakers need to come together to make a meaningful economic and social change. </p> <p>"There's too much at stake for us all to wait for the ultra rich to grow a conscience and voluntarily change their ways," she said.</p> <p>"For that reason, lawmakers must step in and tax extreme wealth, along with the variety of environmentally destructive habits of the world's richest."</p> <p>A recent <a href="https://static1.squarespace.com/static/63fe48c7e864f3729e4f9287/t/6596bfb943707b56d11f1296/1704378297933/G20+Survey+of+those+with+More+than+%241+million+on+Attitudes+to+Extreme+Wealth+and+Taxing+the+Super+Rich.pdf" target="_blank" rel="noopener">survey</a> of almost 2400 millionaires found that 74 per cent of them supported the introduction of a wealth tax to fund improved public services and deal with the cost-of-living crisis.</p> <p>The open letter also said that one-off donations and philanthropy "cannot redress the current colossal imbalance" of societal wealth.</p> <p>"We need our governments and our leaders to lead," the letter said. </p> <p>"The true measure of a society can be found, not just in how it treats its most vulnerable, but in what it asks of its wealthiest members."</p> <p><em>Images: Getty</em></p>

5 ways to make Christmas lunch more ethical this year

<p><em><a href="https://theconversation.com/profiles/rebecca-reynolds-141045">Rebecca Reynolds</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>What we eat matters - not just for our health, but for the planet and other living things too.</p> <p>Most of us know meat consumption <a href="https://www.nature.com/articles/s43016-021-00358-x.epdf">contributes to global warming</a> and many of us are aware of animal cruelty and human exploitation in global food supply chains.</p> <p>So what are some ways we can use our “fork power” to make our Christmas lunch more ethical this year?</p> <h2>1. Replace your turkey or ham with a vegetarian dish</h2> <p>Vegetarian options are not boring or tasteless — just look at this <a href="https://annajones.co.uk/recipe/squash-chestnut-roast">festive squash and chestnut roast</a>.</p> <p>A plant-focused diet has strong <a href="https://eatforum.org/eat-lancet-commission/the-planetary-health-diet-and-you/">environmental benefits</a>. Livestock not only <a href="https://theconversation.com/cop28-begins-4-issues-that-will-determine-if-the-un-climate-summit-is-a-success-from-methane-to-money-218869">produce greenhouse gas</a> when they burp, they take up huge amounts of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9024616/">land and fresh water</a>.</p> <p>Reducing the number of animal products on your plate also reduces the likelihood you are contributing to the suffering of animals. Even though many countries have <a href="https://www.agriculture.gov.au/agriculture-land/animal/welfare/standards-guidelines">ethical standards</a> for the treatment of farm animals, these are not always followed, and many of the practices considered legal <a href="https://www.abc.net.au/news/rural/2023-03-28/pig-slaughter-methods-defended-by-pork-industry/102153822">still cause pain and suffering to animals</a>.</p> <p>While cutting out all animal products can be difficult, any reduction in consumption makes a difference. For example, consider swapping out the brie on your Christmas platter for hummus this year.</p> <h2>2. Choose ‘good fish’</h2> <p>Many of us don’t realise fish and other seafood is often sourced unsustainably, negatively impacting ocean ecosystems and wildlife. An Australian organisation called GoodFish produces a <a href="https://goodfish.org.au/">Sustainable Seafood Guide</a>, where you can find out how ethical the fish you buy is.</p> <p>Unfortunately, many salmon products are <a href="https://goodfish.org.au/sustainable-seafood-guide/?q=salmon">not as sustainable</a> as companies claim them to be. In comparison, farmed Australian barramundi, Murray cod, prawns, oysters and mussels, and wild-caught Australian Eastern and Western rock lobsters are classified as better choices.</p> <p>Additionally, an international not-for-profit organisation called the <a href="https://www.msc.org/en-au">Marine Stewardship Council</a> has an “MSC blue fish tick label” certification scheme, which endorses products from well-managed and sustainable fisheries. Have a look for MSC-certified frozen crumbed fish in your next shop.</p> <h2>3. Choose at least one organic item, such as your roast potatoes</h2> <p><a href="https://www.fao.org/organicag/oa-faq/oa-faq6/en/">Organic agriculture</a> aims to produce food while establishing an ecological balance to prevent soil infertility or pest problems over the longer term. It strengthens the dynamics and carbon storage of soil, stops freshwater pollution with synthetic fertilisers and pesticides, reduces the use of fossil fuels needed to produce these chemicals, and promotes biodiversity.</p> <p>Yes, organic products are more expensive, but you will hopefully now feel they are worth it (you could also look out for organic produce that is reduced in price during “on special” promotions).</p> <h2>4. Choose Fairtrade chocolate</h2> <p>Of course, humans are heavily involved in the production, packaging and transport of the food we eat every day. Organisations such as <a href="https://fairtradeanz.org/">Fairtrade Australia and New Zealand</a> and <a href="https://www.rainforest-alliance.org/">Rainforest Alliance</a> aim to improve the lives of rural farmers and workers in developing countries – who otherwise might get unfair deals for their produce and work (these organisations also target environmental issues).</p> <p>You can buy Fairtrade- and Rainforest Alliance-certified products in supermarkets (and elsewhere), such as chocolate, coffee, tea – and even ice cream.</p> <p>Similarly, there are companies called <a href="https://bcorporation.com.au/find-b-corps/">B Corps</a>, or Certified B Corporations. These are organisations that also care about social and environmental issues. B Corp food products can also be found in supermarkets (and elsewhere), and include things like peanut butter and seaweed snacks.</p> <h2>5. Make friends with your freezer</h2> <p>When we waste food, we are wasting the energy, land, water and chemicals that were used during the <a href="https://www.un.org/en/climatechange/science/climate-issues/food">long process</a> of getting it into your home.</p> <p>Lots of us worry at Christmas about “having enough food for everyone”, and consequently buy too much. Why not talk through your menu plan with someone else before you go shopping, to check that you are not anxiety-buying to feed 50 people (instead of your extended family of ten).</p> <p>But even with calm planning, you may still have leftover food. If this happens, you can get creative with using leftovers on Boxing Day (OzHarvest has some recipes online, including <a href="https://www.ozharvest.org/use-it-up/tips/">Christmas rockyroad</a>), or you can preserve food to eat at a later date using your cool friend, the freezer.<!-- Below is The Conversation's page counter tag.

<p>Bruce Willis' family are "soaking up every moment" with the Hollywood legend, as his health is continuing to deteriorate. </p> <p>The 68-year-old's family have shared new heartbreaking photos of the actor, which show a steep decline in his appearance and capabilities since the onset of his health issues. </p> <p>Willis was diagnosed with frontotemporal dementia at the beginning of 2023, nearly one year after announcing his retirement from acting due to aphasia, which causes difficulties with speech.</p> <p>Since his diagnosis, his family have continued to share updates on the actor's condition.</p> <p>Now, a source close to the family has revealed that the star’s health has worsened in recent weeks, and now there are “more bad days” than good. </p> <p>“Bruce has good days and bad days, but in the last two months, there are many more bad days than good,” a source told <span id="U831940059013HOG"><em><a href="https://www.usmagazine.com/celebrity-news/news/how-bruce-willis-family-is-supporting-him-as-he-battles-dementia/">US Weekly</a></em>.</span></p> <p>“This experience has brought the whole family even closer together. No one knows how much time Bruce has left, so they’re soaking up every moment they get with him.”</p> <p>Another source added that the four-time Golden Globe winner “has around-the-clock care, but at least one family member is always with him.” </p> <p>The beloved Hollywood action star has been spending his days alongside his wife, Emma Heming, ex-wife Demi Moore, and their collective five children, who all care for him throughout his difficult health journey.</p> <p><em>Image credits: Getty Images / Instagram</em></p> <p> </p>

Why we feel like Christmas comes around more quickly each year

<p><em><a href="https://theconversation.com/profiles/ruth-ogden-1182467">Ruth Ogden</a>, <a href="https://theconversation.com/institutions/liverpool-john-moores-university-1319">Liverpool John Moores University</a></em></p> <p>Think back to your childhood. December was the longest of months. It might have been filled with rehearsing school nativity performances, writing up your wishlist and savouring the morning’s advent calendar chocolate. But at times it felt like Santa would never arrive.</p> <p>As an adult it’s a different experience. One minute it’s summer holidays, barbecues and sunburn and then, in the blink of an eye, it’s mince pies, tinsel and turkey. Is it just me, or is Christmas coming around faster?</p> <p>If you cannot believe the festive season is upon us already, you’re not alone. My colleagues and recently conducted a survey of 918 adults in the UK (full results still to be published) and found 77% of respondents agreed Christmas seems to arrive more rapidly each year.</p> <p>One reason may be the way we experience the <a href="https://brill.com/view/journals/time/9/3/article-p275_275.xml">passage of time changes as we age</a>, often resulting in the feeling that <a href="https://journals.sagepub.com/doi/abs/10.1177/0961463x13478052">time speeds up as we get older</a>. For a seven-year- old, the 12 months between Christmases are a huge proportion of their life. For a 45-year-old, those same 12 months are a small portion of their experience. This <a href="https://journals.sagepub.com/doi/10.2466/pms.1975.41.1.235">difference in ratio</a> compresses the relative time between Christmases each year.</p> <p>Our experience of time also changes because we rely on memory to estimate duration. When we judge how long something lasted for, we base our estimate on <a href="https://psycnet.apa.org/record/2004-18721-003">how many memories we made during the period of interest</a>. Whether we are trying to remember the length of a film, car journey or relationship, the number of memories we encoded during it will serve as an indicator of its length.</p> <p>Periods of time in which fewer new memories are made, either because there was a lack of stimulating tasks, novel activities or heightened emotions, are interpreted by <a href="https://philpapers.org/rec/BLORAP">our brains as short</a>.</p> <h2>Where has the year gone</h2> <p>As we age, memory becomes more fallible and we recall less from our day to day lives. We’re also less likely to try new things than when we were younger. Together these factors may contribute to the sensation that less time has passed since last Christmas than we were expecting.</p> <p>Because what we do has such a strong influence on how we experience time, <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0235871">changes to our routine distort the passage of time</a>. A predictable day helps time to flow steadily.</p> <p>This was illustrated on a global scale during the pandemic. One minute we were all going about our daily lives. Then all of a sudden, our routines were scrambled. People from <a href="https://journals.plos.org/plosone/article/comments?id=10.1371/journal.pone.0266261">Buenos Aries</a> to <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0266877">Bagdad</a> reported an overwhelming sense time did not pass as normal during the pandemic.</p> <p>While Christmas does not cause the same level of disruption as a global pandemic, it disrupts our habits.</p> <h2>Can’t wait ‘til it’s Christmas?</h2> <p>Another factor which may make us feel like Christmas is here too fast is the amount of energy we put into anticipating it. For many children, Christmas is arguably the most eagerly awaited event of the year. Advent calendars count down the days until Father Christmas arrives. All this excitement means children pay a lot of attention to the passage of time in the run up to Christmas. Unfortunately for them, focusing on the passage of time <a href="https://digitalcommons.usm.maine.edu/facbooks/472/">typically makes it drag</a>.</p> <p>For most adults, Christmas is less thrilling. So adults probably think less about the countdown. Paying less attention to time <a href="https://pubmed.ncbi.nlm.nih.gov/35902608/">makes it pass more quickly</a>. The effect may have been particularly pronounced this year because, in the post-pandemic normality, life is busier than ever and we have even less time to think about Christmas.</p> <p>Technological change also affects our perception of time. Advances in technology enable us to accomplish more tasks, more quickly, than ever before. This acceleration in the <a href="https://journals.sagepub.com/doi/10.2466/pms.1975.41.1.235">pace of life</a> over the past 20 years may also contribute to the sensation that Christmas now comes around too soon.</p> <h2>Running out of time</h2> <p>Despite paying less attention to time, adults experience significantly more demands on their schedules than children in the run up to Christmas. For children, Christmas happens by magic. For adults however the festive mystique is replaced by large amounts of planning, shopping, wrapping and cooking. The added time pressure created by Christmas may contribute to time passing more quickly.</p> <p>The lack of control children have over Christmas likely increases their level of <a href="https://www.sciencedirect.com/science/article/abs/pii/S1053810015300465">temporal uncertainty</a>. Not knowing when, or indeed if, something will happen can also slow the passage of time.</p> <p>However, maybe we feel like Christmas comes around faster each year because it really does. In years gone by Christmas advertising wasn’t seen until the start of Advent. Nowadays it is normal to see chocolate Santas on the supermarket shelves in early October. This literal <a href="https://www.sciencedirect.com/science/article/abs/pii/S0165176505002284">shifting of the Christmas timeline</a> undoubtedly adds to the psychological sense of Christmas coming earlier.</p> <p>However, retailers’ attempts to increase profits by starting the festive period earlier each year come at a price. When retailer Very.com launched it’s Christmas <a href="https://metro.co.uk/2022/10/10/christmas-advert-in-october-from-very-outrages-viewers-17534895/">advertising campaign on October 7</a> in 2021 there was public outrage. We don’t want to actually see Christmas coming around more quickly. Very didn’t repeat their mistake this year.<!-- Below is The Conversation's page counter tag.

5 reasons why climate change may see more of us turn to alcohol and other drugs

<p><em><a href="https://theconversation.com/profiles/helen-louise-berry-8608">Helen Louise Berry</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> and <a href="https://theconversation.com/profiles/francis-vergunst-230743">Francis Vergunst</a>, <a href="https://theconversation.com/institutions/university-of-oslo-934">University of Oslo</a></em></p> <p>Climate change will affect every aspect of our <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)01859-7/fulltext">health and wellbeing</a>. But its potential harms go beyond the body’s ability to handle extreme heat, important as this is.</p> <p>Extreme weather events, such as floods, droughts, storms and wildfires, are becoming more frequent and severe. These affect our <a href="https://pubmed.ncbi.nlm.nih.gov/36165756/">mental health</a> in a multitude of <a href="https://www.nature.com/articles/s41558-018-0102-4">ways</a>.</p> <p>Coping with climate change can be overwhelming. Sometimes, the best someone can do is to seek refuge in alcohol, tobacco, over-the-counter and prescription drugs, or other psychoactive substances. This is understandable, but dangerous, and can have serious consequences.</p> <p>We outline <a href="https://journals.sagepub.com/doi/full/10.1177/17456916221132739">five ways</a> climate change could increase the risk of harmful substance use.</p> <h2>1. Mental health is harmed</h2> <p>Perhaps the most obvious way climate change can be linked to harmful substance use is by damaging mental health. This <a href="https://onlinelibrary.wiley.com/doi/10.1111/dar.12448">increases the risk</a> of new or worsened substance use.</p> <p>People with a mental disorder are <a href="https://www.hindawi.com/journals/psychiatry/2018/5697103/">at high risk</a> of also having a <a href="https://bmcpsychiatry.biomedcentral.com/articles/10.1186/1471-244X-11-25#:%7E:text=Prevalence%20of%20comorbidity%20in%20epidemiological%20studies&amp;text=Among%20subjects%20with%20an%20alcohol,a%20comorbid%20SUD%20%5B39%5D.">substance-use disorder</a>. This often precedes their mental health problems. Climate change-related increases in the number and nature of extreme events, in turn, are escalating risks to mental health.</p> <p>For example, extreme heat is linked to increased <a href="https://pubmed.ncbi.nlm.nih.gov/27727320/">distress</a> across the whole population. In extreme heat, more people go to the <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2789481">emergency department</a> for psychiatric problems, including for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0048969720338249">alcohol</a> and <a href="https://www.nature.com/articles/s43856-023-00346-1">substance use</a> generally. This is even true for <a href="https://www.sciencedirect.com/science/article/pii/S0048969720325572">a single very hot day</a>.</p> <p>Post-traumatic stress disorder, depression, anxiety and <a href="https://onlinelibrary.wiley.com/doi/abs/10.5694/mja13.10307">other mental health</a> problems are <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2019.00367/full">common</a> at the time of extreme weather events and can persist for months, even years afterwards, especially if people are exposed to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9116266/">multiple events</a>. This can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6101235/">increase</a> the likelihood of using substances as a way to cope.</p> <h2>2. Worry increases</h2> <p>With <a href="https://climatecommunication.yale.edu/publications/climate-change-in-the-american-mind-beliefs-attitudes-december-2022/">increasing public awareness</a> of how climate change is endangering wellbeing, people are <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/articles/worriesaboutclimatechangegreatbritain/septembertooctober2022#:%7E:text=The%20level%20of%20worry%20about,lives%20right%20now%20(29%25).">increasingly worried</a> about what will happen if it remains unchecked.</p> <p>Worrying isn’t the same as meeting the criteria for a mental disorder. But <a href="https://www.undp.org/publications/peoples-climate-vote">surveys</a> show climate change generates complex emotional responses, <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(21)00278-3/fulltext">especially in children</a>. As well as feelings of worry, there is anxiety, fear, guilt, anger, grief and helplessness.</p> <p>Some <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2904966/">emotional states</a>, such as <a href="https://www.pnas.org/doi/full/10.1073/pnas.1909888116">sadness</a>, are linked with long-term tobacco use and also make substance use <a href="https://pubmed.ncbi.nlm.nih.gov/16011392/">relapse</a> more likely.</p> <h2>3. Physical injuries hurt us in many ways</h2> <p>Physical injuries caused by extreme weather events – such as smoke inhalation, burns and flood-related cuts and infections – increase the risk of harmful substance use. That’s partly because they <a href="https://pubmed.ncbi.nlm.nih.gov/20033251/">increase</a> the risk of psychological distress. If injuries cause long-term illness or disability, consequent feelings of hopelessness and depression can dispose some people to self-medicate with alcohol or other drugs.</p> <p>Substance use itself can also generate long-term physiological harm, disabilities or other chronic health problems. These are <a href="https://www.tandfonline.com/doi/abs/10.3109/00952999609001655">linked with</a> higher rates of harmful substance use.</p> <h2>4. Our day-to-day lives change</h2> <p>A single catastrophic event, such as a storm or flood, can devastate lives overnight and change the way we live. So, too, can the more subtle changes in climate and day-to-day weather. Both can disrupt behaviour and routines in ways that risk new or worsened substance use, for example, using stimulants to cope with fatigue.</p> <p>Take, for example, hotter temperatures, which disrupt <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(22)00209-3?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS2590332222002093%3Fshowall%3Dtrue">sleep</a>, undermine <a href="https://jhr.uwpress.org/content/57/2/400">academic performance</a>, <a href="https://www.nature.com/articles/s41562-017-0097">reduce physical activity</a>, and promote <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(22)00173-5/fulltext">hostile language</a> and <a href="https://www.cambridge.org/core/elements/abs/climate-change-and-human-behavior/F64471FA47B8A6F5524E7DDDDE571D57">violent behaviour</a>.</p> <h2>5. It destabilises communities</h2> <p>Finally, climate change is destabilising the socioeconomic, natural, built and geopolitical <a href="https://www.nature.com/articles/s41558-018-0102-4">systems</a> on which human wellbeing – <a href="https://theconversation.com/climate-change-and-health-ipcc-reports-emerging-risks-emerging-consensus-24213">indeed survival</a> – depends.</p> <p>Damaged infrastructure, agricultural losses, school closures, homelessness and displacement are significant <a href="https://www.nature.com/articles/s41558-018-0102-4">sources of psychosocial distress</a> that prompt acute (short-term) and chronic (long-term) stress responses.</p> <p><a href="https://doi.org/10.1196/annals.1441.030">Stress</a>, in turn, can <a href="https://doi.org/10.1007/s002130100917">increase</a> the risk of <a href="https://link.springer.com/article/10.1007/s002130100917">harmful substance use</a> and make people more likely to relapse.</p> <h2>Why are we so concerned?</h2> <p>Substance-use disorders are economically and socially <a href="https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(18)30337-7/fulltext">very costly</a>. Risky substance use that doesn’t meet the criteria for a formal diagnosis <a href="https://digitalcommons.fiu.edu/srhreports/health/health/32/">can also harm</a>.</p> <p>Aside from its direct physical harm, harmful substance use disrupts <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3843305/">education</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3234116/">employment</a>. It increases the risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6676144/">accidents</a> and <a href="https://www.tandfonline.com/doi/abs/10.1080/09595230600944479">crime</a>, and it undermines social relationships, intimate <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4795906/#:%7E:text=Results%20indicated%20that%20alcohol%20use,drinkers%20with%20low%20relationship%20satisfaction.">partnerships</a> and <a href="https://www.cambridge.org/core/journals/development-and-psychopathology/article/abs/longitudinal-relations-between-parental-drinking-problems-family-functioning-and-child-adjustment/CE508589A9E799FD6DC9E23DF364FB8F">family functioning</a>.</p> <h2>Politicians take note</h2> <p>As we head towards the <a href="https://www.cop28.com">COP28 global climate talks</a> in Dubai, climate change is set to hit the headlines once more. Politicians know climate change is undermining human health and wellbeing. It’s well past time to insist they act.</p> <p>As we have seen for populations as a whole, there are multiple possible ways for climate change to cause a rise in harmful substance use. This means multidimensional <a href="https://www.nature.com/articles/s41558-018-0102-4">prevention strategies</a> are needed. As well as addressing climate change more broadly, we need strategies including:</p> <ul> <li> <p>supporting vulnerable individuals, especially <a href="https://journals.sagepub.com/doi/full/10.1177/21677026211040787">young people</a>, and marginalised commmunities, who are <a href="https://www.nature.com/articles/s41558-018-0102-4">hit hardest</a> by extreme weather-related events</p> </li> <li> <p>focusing health-related policies more on broadscale health promotion, for example, healthier eating, active transport and community-led mental health support</p> </li> <li> <p>investing in climate-resilient infrastructure, such as heat-proofing buildings and greening cities, to prevent more of the destabilising effects and stress we know contributes to mental health problems and harmful substance use.</p> </li> </ul> <p>There is now <a href="https://news.un.org/en/story/2022/10/1129912">no credible pathway</a> to avoiding dangerous climate change. However, if <a href="https://carnegieendowment.org/2023/01/12/climate-protests-tracking-growing-unrest-pub-88778#:%7E:text=These%20are%20just%20a%20few,even%20more%20numerous%20and%20influential.">increasing rates</a> of climate protests are anything to go by, the world may finally be ready for radical change – and perhaps for reduced harmful substance use.<!-- Below is The Conversation's page counter tag.

When it comes to weight, your ‘diet’ is much more than what you eat

<p>Atkins, keto, palaeo, gluten-free, low-carb, low-fat, high-fat, raw, vegan, vego, pescatarian – phew, that’s a lot of different diets!</p> <div class="copy"> <p>And it’s by no means an exhaustive list.</p> <p>The old adage ‘you are what you eat’ has come to be a mantra for good diet and health. It was originally coined by 19th-century German philosopher Ludwig Feuerbach, himself drawing on commentary by an earlier French gourmand Anthelme Brillat-Savarin.</p> <p>Increasingly, science is finding new connections between diet and our overall picture of health. You may have heard how our gut microbiome acts as a second brain, or that avoiding unprocessed foods can lead to all-cause mortality.</p> <p>But when it comes to many fad diets that promise quick weight loss or improved health, the science can sometimes be skimp. This can change over time as researchers test the influence of diet on general health, weight management and as a medical treatment.</p> <p>The <a href="https://cosmosmagazine.com/health/mediterranean-diet-heart-dementia/">Mediterranean diet</a> is probably closest to the mark as a lifestyle of choice, in terms of overall health, nutrition, and diet science. It emphasises <a href="https://cosmosmagazine.com/health/nutrition/plant-based-diets-could-prevent-type-2-diabetes/">fruit and vegetable</a> consumption, with some wholegrain breads and cereals, legumes, nuts, seeds and fish, with olive oil as a primary fat source.</p> <p>This diet is either explicitly endorsed by many health authorities around the world such as the <a href="https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/nutrition-basics/mediterranean-diet" target="_blank" rel="noreferrer noopener">American Heart Association</a>, the <a href="https://www.racgp.org.au/clinical-resources/clinical-guidelines/handi/handi-interventions/nutrition/mediterranean-diet-for-reducing-cardiovascular-dis" target="_blank" rel="noreferrer noopener">Royal Australian College of General Practitioners</a> as a diet for lowering cardiovascular disease risk, or used as a basis for other recommendations. The World Health Organization also <a href="https://www.who.int/europe/news/item/07-05-2018-fostering-healthier-and-more-sustainable-diets-learning-from-the-mediterranean-and-new-nordic-experience" target="_blank" rel="noreferrer noopener">advises</a> on ways for the Mediterranean and similar New Nordic diets to be implemented as <a href="https://iris.who.int/bitstream/handle/10665/326264/9789289053013-eng.pdf?sequence=3" target="_blank" rel="noreferrer noopener">health policy</a>.</p> <p>But diet might be better considered about more than what goes in one’s mouth.</p> <p>Dr Evangeline Mantzioris, Program Director of the Nutrition and Food Sciences Degree at the University of South Australia, says a truer interpretation of the world extends beyond merely food and drink.</p> <p>“The word diet actually derives from the Greek word <em>diaita</em>, which means the way you choose to live your life,” Mantzioris told the <a href="https://cosmosmagazine.com/tag/debunks/" target="_blank" rel="noreferrer noopener"><em>Debunks</em> podcast.</a></p> <p>“So it’s not just about the food, it’s about the exercise, it’s about the social interaction, it’s about the rest. It’s about the sleep. It’s all of that.”</p> <p>The WHO’s 2019 Health Evidence Network Synthesis Report also acknowledges both social and sleep components of the lifestyle, noting shared eating practices, post-meal siestas and lengthy meal times all contribute to positive health effects.</p> <p>In terms of the nutritional component, Mantzioris notes that adherence to the diet requires not just an uptake of olive oil, but cutting down on less beneficial foods and an active lifestyle.</p> <p>“It’s not just the olive oil, it’s dropping down the meat, it’s mainly a plant food diet, it’s purposeful exercise,” she says.</p> <p>“I’m always a little bit nervous when people just talk about the diet and the food without considering the rest of it.</p> <p>“In the 60s, when the health benefits of the Mediterranean diet were seen […] they were out there harvesting, growing their food, preparing their food, doing all that sort of purposeful exercise in the outdoor environment, often in quite steep terrain. So that is just as important.</p> <p>“The Mediterranean diet continues to be shown to be quite healthy and beneficial in terms of improving chronic disease risk, even without weight loss.”</p> <p>Mantzioris says that the diet has also been shown to improve cognitive and mental health outcomes.</p> <p>Diet is the focus of the latest episode of <em>Debunks</em> from Cosmos and 9Podcasts, where we dive not simply into what makes a good diet, but the principles that dieticians and nutritionists look for when recommending one for a patient to consider.</p> <p><iframe title="Weight: Do diets actually work?" src="https://omny.fm/shows/debunks/weight-do-diets-actually-work/embed?style=Artwork" width="100%" height="180" frameborder="0"></iframe> <!-- Start of tracking content syndication.

Extreme weather is landing more Australians in hospital – and heat is the biggest culprit

<p><em><a href="https://theconversation.com/profiles/amy-peden-1136424">Amy Peden</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Hospital admissions for injuries directly attributable to extreme weather events – such as heatwaves, bushfires and storms – have increased in Australia over the past decade.</p> <p>A new <a href="https://www.aihw.gov.au/reports/injury/extreme-weather-injuries/contents/about">report</a> from the Australian Institute of Health and Welfare (AIHW) shows 9,119 Australians were hospitalised for injuries from extreme weather from 2012-22 and 677 people died from these injuries in the decade up to 2021.</p> <p>In 2021-22, there were 754 injury hospitalisations directly related to extreme weather, compared to 576 in 2011-12.</p> <p>Extreme heat is responsible for most weather-related injuries. Exposure to prolonged natural heat can result in physical conditions ranging from mild heat stroke, to organ damage and <a href="https://www.dea.org.au/wp-content/uploads/2021/01/DEA-Fact-Sheet_HeatwavesWEB.pdf">death</a>.</p> <p>As Australia heads into summer with an El Niño, it’s important understand and prepare for the health risks associated with extreme weather.</p> <h2>A spike every three years</h2> <p>Extreme weather-related hospitalisations have spiked at more than 1,000 cases every three years, with the spikes becoming progressively higher. There were:</p> <ul> <li>1,027 injury hospitalisations in 2013–14</li> <li>1,033 in 2016–17</li> <li>1,108 in 2019–20.</li> </ul> <p><iframe id="vLaas" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/vLaas/1/" width="100%" height="400px" frameborder="0"></iframe></p> <p>In each of these three years, extreme heat had the biggest impact on hospital admissions and deaths.</p> <p><iframe id="P03sm" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/P03sm/1/" width="100%" height="400px" frameborder="0"></iframe></p> <p>Extreme heat accounted for 7,104 injury hospitalisations (78% of all injury hospitalisations) and 293 deaths (43% of all injury deaths) in the ten year period analysed.</p> <p>In 2011-12, there were 354 injury hospitalisations directly related to extreme heat. This rose to 579 by 2021-22.</p> <h2>El Niño and La Niña</h2> <p>Over the past three decades, extreme weather events have increased in <a href="https://www.ipcc.ch/report/ar5/syr/">frequency</a> and <a href="http://www.bom.gov.au/state-of-the-climate/">severity</a>.</p> <p>In Australia, El Niño drives a period of reduced rainfall, warmer temperatures and increased bushfire danger.</p> <p>La Niña, on the other hand, is associated with above average rainfall, cooler daytime temperatures and increased chance of tropical cyclones and flood events.</p> <p>Although similar numbers of heatwave-related hospitalisations occurred in El Niño and La Niña years studied, the number of injuries related to bushfires was higher in El Niño years.</p> <p>During the 2019–20 bushfires, in the week beginning January 5 2020, there were 1,100 more hospitalisations than the previous five-year average, an 11% increase.</p> <p>Although El Niño hasn’t directly been proved as the cause for these three spikes, according to the Bureau of Meteorology, two of the three years (2016-17 and 2019-20) were El Niño summers. And the other year (2013-14) was the warmest neutral year on record at that time.</p> <h2>Regional differences</h2> <p>Exposure to excessive natural heat was the most common cause leading to injury hospitalisation for all the mainland states and territories. From 2019 to 2022, there were 2,143 hospital admissions related to extreme heat, including:</p> <ul> <li>717 patients from Queensland</li> <li>410 from Victoria</li> <li>348 from NSW</li> <li>267 from South Australia</li> <li>266 from Western Australia</li> <li>73 from the Northern Territory</li> <li>23 from the ACT</li> <li>19 from Tasmania.</li> </ul> <figure class="align-center "><img src="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=632&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=632&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=632&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=794&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=794&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=794&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="attribution"><a class="source" href="https://www.aihw.gov.au/reports-data/latest-reports">AIHW National Hospital Morbidity Database</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></span></figcaption></figure> <p>The report also includes state and territory data on hospitalisations related to extreme cold and storms.</p> <p>During the ten-year period analysed, there were 773 injury hospitalisations and 242 deaths related to extreme cold. Extreme rain or storms accounted for 348 injury hospitalisations and 77 deaths.</p> <p>From 2019 to 2022, there were 191 hospitalisations related to extreme cold, with Victoria recording the highest number (51, compared to 40 in next-placed NSW). During the same period there were 111 hospitalisations related to rain and storms, with 52 occurring in NSW and 28 in Queensland.</p> <h2>What about for bushfires?</h2> <p>Over the ten-year period studied, there were 894 hospitalisations and 65 deaths related to bushfires.</p> <p>Bushfire-related injury hospitalisations and deaths peaked in 2019–20, an El Niño year with 174 hospitalisations and 35 deaths. The two most common injuries that result from bushfires are smoke inhalation and burns.</p> <p>During the 2019–20 bushfires, in the week beginning 5 January 2020 there were 1,100 more respiratory hospitalisations than the previous five-year average, an 11% increase.</p> <p>The greatest increase in the hospitalisation rate for burns was 30% in the week beginning December 15 2019 — 0.8 per 100,000 persons (about 210 hospitalisations), compared with the previous 5-year average of 0.6 per 100,000 (an average of 155 hospitalisations).</p> <h2>Some people are particularly vulnerable</h2> <p>Anyone can be affected by extreme weather-related injuries but some population groups are more at risk than others. This includes older people, children, people with disabilities, those with pre-existing or chronic health conditions, outdoor workers, and those with greater <a href="https://www.mdpi.com/2071-1050/15/1/813">socioeconomic disadvantage</a>.</p> <p>People in these groups may have reduced capacity to avoid or reduce the health impacts of extreme weather conditions, for example older people taking medication may be less able to regulate their body temperature. “Thermal inequity” includes people living in poor quality housing who have difficulty accessing adequate heating and cooling.</p> <p>For heat-related injuries between 2019–20 and 2021–22, people aged 65 and over were the most commonly admitted to hospital, followed by people aged 25–44.</p> <p>Across age groups, men had higher numbers of heat related injury hospitalisations than women. This difference was most notable among those aged 25-44 and 45-64 years, where over twice as many men were hospitalised due to extreme heat as women.</p> <h2>We still don’t have a full picture</h2> <p>The AIHW data only includes injuries which were serious enough for patients to be admitted to hospital; it doesn’t include cases where patients treated in an emergency department and sent home without being admitted.</p> <p>It includes injuries that were directly attributable to weather-related events but does not include injuries that were indirectly related. For example, it doesn’t include injuries from road traffic accidents that occur due to wet weather, since the primary cause of injury would be recorded as “transport”.</p> <p>Improved surveillance of weather-related injuries could help the health system and the community better prepare for responding to extreme weather conditions. For example, better data aids communities in predicting what resources will be needed during periods of extreme weather.</p> <p>A more complete picture of injuries during weather events could also be used to inform people of actions they can take to protect their own health. Given a predicted hot summer, this could be a matter of life or death.</p> <p><em>This article was co-authored by Sarah Ahmed and Heather Swanston from the Injuries and System Surveillance Unit at the Australian Institute of Health and Welfare.</em><!-- Below is The Conversation's page counter tag.
