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.

Huge reward to help solve cold case of missing mum

<p>Police are offering a $500,000 reward for information to help solve a cold case that suspect was a murder. </p> <p>Tammy Lisa Dyson, also known as Tamela Menzies, was 23 when went missing from the Currumbin area in 1995. </p> <p>The mother of two was picked up from a drug rehab clinic by a woman claiming to be her sister on July 20, 1995 and has not been seen since. </p> <p>Dyson was born and raised in Victoria before moving to Brisbane in 1988, where she worked in the adult entertainment industry under the nickname "Pebbles". </p> <p>Police believe she began mixing with criminals and using drugs while working in strip clubs on the Gold Coast.</p> <p>In early 1995 Dyson arranged for her young sons, Jyles and Rainey, to stay with their grandmother in Victoria temporarily.</p> <p>A few months later she made a distressed call to her sister Olivia, who said she had been assaulted. </p> <p>Olivia and her partner then dropped Dyson off to a drug rehabilitation centre at Currumbin on the Gold Coast, and on July 20, 1995 she was picked up by someone claiming to be her sister. </p> <p>The following day, Tammy completed a statutory declaration signed by a Justice of the Peace in Tweed Heads, giving custody of her children and her possessions to her mother.</p> <p>She also called her sister one last time, with Olivia recalling that Tammy "didn't sound like herself" and she had mentioned underworld figures. </p> <p>Police have received a number of reported sightings of Tammy since 1995 but all proof of life inquiries have  been proven negative.</p> <p>In 2012, the Queensland coroner said that they believed Tammy was deceased and indicated that she may have been a victim of violence, although a certain date, time and cause of death have not been determined. </p> <p>Police are now offering the huge reward for new information and immunity from prosecution for any accomplice who comes forward.</p> <p>"Tammy associated with criminals that were known to police and vanished without a trace after giving custody of her children and possessions to her mother; we believe the circumstances of her disappearance is suspicious," Detective Senior Sergeant Tara Kentwell said.</p> <p>On Wednesday, her sons, who were only three and one when their mother disappeared, made an emotional appeal for public help to find her. </p> <p>"Growing up without mum and not knowing what happened to her has been very hard," Jyles Lebler said through tears during a media conference. </p> <p>"Whoever has picked her up, I'm not saying they have done something but they must know something bad has happened."</p> <p>"We hope we find out what to mum to give grandma some closure before it's too late," Rainey added.</p> <p><em>Images: Queensland Police</em></p>

Awful new details emerge after man's fatal fall from hot air balloon

<p><strong>Warning: Disturbing details</strong></p> <p>New details have emerged of the moments before a man tragically fell to his death from a <a href="https://www.oversixty.com.au/news/news/man-dies-after-falling-from-hot-air-balloon-over-melbourne" target="_blank" rel="noopener">hot air balloon</a>. </p> <p>The man was one of ten people onboard the hot air balloon ride, which took off at around 7am on Monday. </p> <p>A video obtained by 7News, shows the man, dressed in a brown jumper, taking in the view over the city alongside other guests. </p> <p>Witnesses have also reported that the man looked fine and was even chatting with the ride operator about politics as the balloon launched into the air. </p> <p>As the ride reached around 450metres, just ten minutes later, with no warning whatsoever he shockingly exited the basket in what was reported to be an act of self-harm and plunged to his death. </p> <p>The pilot immediately made a distressed may day call as horrified passengers and motorists witnessed him fall through the air. </p> <p>Passengers onboard another hot air balloon, which was launched at the same time, recalled hearing the distress calls over the radio approximately 15 minutes into their ride. </p> <p>Not long after emergency services arrived at the horrifying scene in Albert Street, Preston in the city's north-east, where his body was found in a front yard.</p> <p>One witness recalled the incident and told the <em>Today </em>show: "My brother heard like a loud bang, almost like something like a large item falling in your house. And it wasn’t until we heard all the sirens that we came out."</p> <p>Passengers onboard the hot air balloon have been offered counselling by the operator, with officers currently preparing a report for the coroner. </p> <p><em>Images: 7News/ Daily Mail</em></p>

"Cruel" shopper slammed for leaving dog in hot car

<p>A woman has been slammed on social media for allegedly leaving her dog in an unattended car for 40 minutes on a hot day. </p> <p>The incident occurred at Warringah Mall in Sydney's north on Monday, when temperatures reached up to 28 degrees.</p> <p>Claire, claimed the dog-owner pulled up next to her in an undercover car park, and then watched the woman leave her pet locked in an unattended car while she shopped. </p> <p>"Myself and my mother waited till she got back," she told <em>Yahoo News Australia</em>. </p> <p>"It was around 3.15pm and she didn’t come back till just before 4pm".</p> <p>During that time, Claire said she called security, who attempted to contact the owner via a mobile number on the dog's harness. She also tried calling the RSPCA and police but claimed that not much could be done.</p> <p>When the owner finally returned, Claire questioned her about leaving the "panting and drooling" animal unattended, but the woman reportedly  just "laughed and scoffed" before "driving away as quick as possible".</p> <p>Claire shared photos of the pup on Facebook  and criticised the owner, for her "absolute irresponsibility and disgusting behaviour", calling her an "absolute d**khead". </p> <p> "People like you should not own animals," she wrote. </p> <p>While many agreed that the woman's actions were "absolutely awful," a few others argued the act was fine as the car was undercover and "the dog doesn't look hot and distressed at all."</p> <p>Another person who claimed to know the owner, said that the woman's car "has an aircon function which allows the air-conditioning to run when the engine is not running" and the pet is generally "very spoiled and happy". </p> <p>A few others disagreed, and said that the act was "cruel" and "simply disgusting" regardless. </p> <p>"Undercover or not you don't lock a baby in a car, you don't lock an animal in a car ... no excuse," one wrote.</p> <p>An RSPCA spokesperson has also spoken out and said that leaving a dog inside a car unattended is "always dangerous" no matter the location or the temperature outside. </p> <p>They said that even on mild days, temperatures in a car can "rapidly heat up" and can reach "double" the outside temperature.</p> <p>"When it’s 22 degrees Celsius outside, the inside of a car can reach a stifling 47 degrees and this is no environment for a dog," the spokesperson said.</p> <p><em>Image: Facebook</em></p>

It’s extremely hot and I’m feeling weak and dizzy. Could I have heat stroke?

<p><em><a href="https://theconversation.com/profiles/lily-hospers-1060107">Lily Hospers</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/james-smallcombe-1412548">James Smallcombe</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ollie-jay-114164">Ollie Jay</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Australia is braced for a hot, dry summer. El Nino is back, and this year it will occur alongside an <a href="https://www.abc.net.au/news/2023-08-22/positive-indian-ocean-dipole-to-coincide-with-el-nino/102756378">Indian Ocean dipole</a>, a climate pattern which will further amplify this hot and dry effect.</p> <p>Hot weather can place great stress on our bodies. When the environmental conditions exceed the limit at which we can adequately cope, we can suffer from heat-related illnesses.</p> <p>Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke.</p> <h2>What are the signs and symptoms?</h2> <p>If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness.</p> <p>Mild <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">symptoms of heat exhaustion</a> can often be treated at home by reducing your levels of physical activity, finding shade, removing excess clothing, hydrating with water and perhaps even taking a cool shower.</p> <p>If left unchecked, heat exhaustion can progress to the far more serious condition of heat stroke, where your core temperature climbs upwards of 40°C. <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">Symptoms</a> can develop rapidly and may include confusion, disorientation, agitation, convulsions, or it could even result in a coma.</p> <p>Heat stroke is a medical emergency and requires urgent treatment. Call an ambulance and start rapid, aggressive cooling by immersing the person in cold water (such as a cold bath). If this isn’t possible, apply ice packs to their neck, armpits and groin and cover the skin with lots of cool water.</p> <p>When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second.</p> <h2>Why do we overheat?</h2> <p>Environmental conditions play an important role in determining our heat stress risk. If the air temperature, humidity and levels of sun exposure are high, we are much more likely to dangerously overheat.</p> <p>When the body gets hot, the heart pumps more warm blood to our skin to help lose heat. As air temperature rises, this way of shedding heat becomes ineffective. When air temperature is higher than the temperature of the skin (normally around 35°C), we start gaining heat from our surroundings.</p> <p>Sweating is by far our most effective physiological means of keeping cool. However, it is the <em>evaporation</em> of sweat from our skin that provides cooling relief.</p> <p>When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates.</p> <p>Our physical activity levels and clothing also impact heat stress risk. When we move, our bodies generate metabolic heat as a by-product. The more intense physical activity is, the more heat we must lose to avoid dangerous rises in core temperature.</p> <p>Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool.</p> <h2>Who is most vulnerable in the heat?</h2> <p>Some people <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/people-most-at-risk.aspx">are at greater risk</a> of developing heat illness than others. This can result from physiological limitations, such as a decreased capacity to sweat, or a reduced capacity to adapt our behaviour. When these two risk factors coincide, it’s a perfect storm of vulnerability.</p> <p>Take, for example, an elderly outdoor agricultural worker. Being aged over 60, their physiological capacity to sweat is reduced. The worker may also be wearing heavy safety clothing, which may further limit heat loss from the body. If they don’t slow down, seek shelter and adequately hydrate, they become even more vulnerable.</p> <p>When a person dies of heat stroke – which is relatively easy to diagnose – heat will be listed as a cause of death on a death certificate. Between 2001 and 2018 in Australia, 473 heat-related deaths were <a href="https://www.sciencedirect.com/science/article/pii/S2212420921006324">officially reported</a>.</p> <p>However, the true association between heat and death is thought to be far greater, with an <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(20)30100-5/fulltext">estimated 36,000 deaths</a> in Australia between 2006 and 2017.</p> <p>This is because most people who die during extreme heat events do not die from heat stroke. Instead, they they die of <a href="https://www.nejm.org/doi/full/10.1056/nejm199607113350203">other medical complications</a> such as cardiovascular or renal collapse, as additional strain is placed on essential organs such as the heart and kidneys.</p> <p>People with underlying health conditions are more likely to succumb to heat-associated complications before they develop critical core temperature (over 40°C) and heat stroke.</p> <p>In such cases, while the additional physiological strain imposed by the heat probably “caused” the death, the official “cause of death” is often listed as something else, such as a heart attack. This can make understanding the true health burden of extreme heat more difficult.</p> <h2>How to stay safe in the heat</h2> <p>Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat.

“Deeply disappointed”: The Wiggles hit out at council’s “harsh” use of iconic song

<p dir="ltr">The Wiggles have taken aim at the Western Australian city of Bunbury for using their iconic song in a “harsh” way. </p> <p dir="ltr">The childrens’ entertainers found out the local council had been playing their song <em>Hot Potato</em> on an endless loop to deter homeless people from congregating. </p> <p dir="ltr">The song had been playing at the Graham Bricknell Music Shell, a stage in one of the town’s parks, that plays host to bands and events. </p> <p dir="ltr">When not in use for entertainment purposes, homeless people would gather under the shell and pitch tent to seek shelter from the elements. </p> <p dir="ltr">After being alerted to the fact that their song was being used in such a callous way, The Wiggles contacted The City of Bunbury and banned them from using the song.</p> <p dir="ltr">In a statement given to the <a href="https://thewest.com.au/entertainment/the-wiggles-slap-the-city-of-bunbury-with-music-ban-over-homelessness-row--c-12413889" target="_blank" rel="noopener"><em>West Australian</em>, </a>they said, “The Wiggles’ music is created to bring joy and happiness to children and families around the world, and we are deeply disappointed to hear that it is being used in any other way.”</p> <p dir="ltr">The council had been using the Wiggles’ song for around six months before the band issued their ban. </p> <p dir="ltr">Mayor of Bunbury Jaysen Miguel defended his decision to play the music, saying, “The City of Bunbury has been running music on and off there for the past six months, as happens across Australia and across the world where you can have music in certain areas to deter anti-social behaviours.”</p> <p dir="ltr">“But... there has been a known problem where people are getting in and turning the music up to full bore.”</p> <p dir="ltr">Local homeless cafe provider Intown Centre said the council needed a better response to the homelessness crisis, as Chair David Bailey said, “In the last couple of days, I have been walking around and I have heard it, but I did not think it was the council.”</p> <p dir="ltr">“I thought it was someone with a CD player,” he said.</p> <p dir="ltr">“It did strike me as odd. It is harsh . . . (and) there needs to be a better response.”</p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

You’ve heard of long COVID, but did you know there might also be a long cold?

<p><em><a href="https://theconversation.com/profiles/giulia-vivaldi-1476903">Giulia Vivaldi</a>, <a href="https://theconversation.com/institutions/queen-mary-university-of-london-1745">Queen Mary University of London</a></em></p> <p>At least <a href="https://www.nature.com/articles/s41579-022-00846-2">10% of people</a> infected with SARS-CoV-2, the virus that causes COVID, have symptoms that last more than four weeks after the infection. With more than <a href="https://covid19.who.int/">770 million infections</a> to date, this translates to tens of millions of people living with the long-term consequences of COVID, known as “long COVID”.</p> <p><a href="https://www.nature.com/articles/s41579-022-00846-2">More than 200 symptoms</a> of long COVID have been studied, with some of the most common being fatigue, breathlessness and cognitive difficulties, such as memory problems or “brain fog”. The condition can be debilitating – many people have to <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(23)00387-5/fulltext">reduce their working hours</a> or are <a href="https://ifs.org.uk/publications/long-covid-and-labour-market">unable to work entirely</a>.</p> <p>But COVID may not be alone in causing long-lasting symptoms.</p> <p>In a <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(23)00428-5/fulltext">new paper</a>, my colleagues and I report the findings of a study comparing long-term symptoms reported by people who experienced different types of acute respiratory infection. We asked more than 10,000 people to report on 16 symptoms commonly found in long COVID, such as fatigue, breathlessness, aches and pains, and dizziness. We then compared how common these symptoms were among three groups: people who had reported COVID, those who had reported another acute respiratory infection (but had tested negative for COVID), and those who had not reported either infection.</p> <p>We focused on long-term symptoms by only including people who had been infected more than four weeks earlier. We also took into account people’s general health before they were infected, and whether they had any existing respiratory conditions.</p> <p>Our study showed that all the symptoms considered were more common in people with previous COVID than in people with no infections, regardless of whether they reported long COVID. But this finding wasn’t unique to COVID. Almost all the symptoms we looked at were also more common in people with non-COVID respiratory infections than in those with no infection.</p> <p>In other words, our findings hinted towards the existence of a “long cold”: long-lasting health effects from other respiratory infections, such as colds, flu, or pneumonia, that are currently going unrecognised.</p> <p>Some of the most common symptoms of the long cold include coughing, stomach pain, and diarrhoea. These symptoms were reported an average of 11 weeks after the infection. While a severe initial infection seems to increase the risk of long-term symptoms, our research does not yet tell us why some people suffer extended symptoms while others do not.</p> <h2>Important differences</h2> <p>Importantly, we have no evidence that symptoms of the long cold have the same severity or duration as long COVID. In fact, we saw some important differences in the symptoms reported in the two groups, with those recovering from COVID more likely to experience light-headedness or dizziness and problems with taste and smell.</p> <p>These findings shine a light not only on the impact of long COVID on people’s lives, but also other respiratory infections.</p> <p>A lack of awareness, or even the lack of a common term, such as “long cold” or “long flu”, prevents both reporting and diagnosis of these conditions. And people who do report their long cold may still struggle to get a diagnosis, owing to the wide range of symptoms and <a href="https://www.nature.com/articles/s41591-022-01810-6">lack of diagnostic tests</a>.</p> <p>Long-lasting symptoms after respiratory infections are not a new phenomenon. Studies in survivors of two previous coronavirus outbreaks – the severe acute respiratory syndrome (Sars) pandemic and the Middle East respiratory syndrome (Mers) outbreak – have found long-term impacts on <a href="https://www.rcpjournals.org/content/clinmedicine/21/1/e68">lung function, quality of life and mental health</a>. And some people hospitalised with influenza A have experienced <a href="https://www.nature.com/articles/s41598-017-17497-6">respiratory and psychological problems</a> at least two years after being discharged from hospital.</p> <p>But most of the research so far has focused on people with severe disease, often severe enough to be hospitalised. Little is known about the long-term effects respiratory infections might have among people whose acute disease episode is less severe.</p> <p>Long COVID has bucked this trend, being studied in people with all levels of severity of the initial infection. This is in large part due to <a href="https://www.sciencedirect.com/science/article/pii/S0277953620306456">strong patient advocacy</a>, showing that it can affect even those with mild initial symptoms.</p> <p>In demanding recognition of their condition, people with long COVID have cast a much-needed spotlight on post-infection syndromes more generally. Now is the time to improve our understanding, diagnosis and treatment of these conditions. Let’s not wait for another pandemic.<!-- Below is The Conversation's page counter tag.

Lots of women try herbs like black cohosh for menopausal symptoms like hot flushes – but does it work?

<p><em><a href="https://theconversation.com/profiles/sasha-taylor-1461085">Sasha Taylor</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Menopause is the stage of life where the ovaries stop releasing eggs and menstrual periods cease. Most Australian women go through menopause between <a href="https://www.nature.com/articles/nrdp20154">45 and 55</a> years of age, with the average age being 51 years, although some women may be younger.</p> <p>Hot flushes and night sweats are <a href="https://www.nature.com/articles/nrendo.2017.180">typical symptoms</a> of menopause, with vaginal dryness, muscle and joint pains, mood changes and sleep disturbance also commonly reported. Up to <a href="https://pubmed.ncbi.nlm.nih.gov/25706184/">75% of women</a> experience menopausal symptoms, with nearly 30% severely affected.</p> <p>These symptoms can negatively impact day-to-day life and wellbeing. The main therapies available include menopausal hormone therapy (MHT) and non-hormonal prescription therapy. Some women will elect to try complementary and alternative medicines, such as herbal medicines and nutritional supplements. Black cohosh is one of them.</p> <h2>What causes hot flushes</h2> <p>The cause of hormonal hot flushes (also called hot flashes) still isn’t completely understood, but the decline in oestrogen at menopause appears to play a role in a process that involves the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3833827/">area of the brain that regulates temperature</a> (the hypothalamus).</p> <p>Factors linked to a greater likelihood of hot flushes include <a href="https://pubmed.ncbi.nlm.nih.gov/19675142/">being overweight or having obesity</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/25706184/">smoking</a>.</p> <p>MHT, previously known as hormone replacement therapy (HRT), usually includes oestrogen and is the <a href="https://pubmed.ncbi.nlm.nih.gov/26444994/">most effective treatment</a> for menopausal symptoms, such as hot flushes. But women may choose complementary and alternative medicines instead – either because they shouldn’t take hormone therapy, for example because they have breast cancer, or because of personal preference.</p> <p>Close <a href="https://pubmed.ncbi.nlm.nih.gov/26224187/">to 40%</a> of Australian women report using complementary and alternative medicines for menopausal symptoms, and up to 20% using them specifically to treat hot flushes and sweats.</p> <h2>A long history</h2> <p>Complementary and alternative medicines have a long history of use in many cultures. Today, their potential benefits for menopausal symptoms are promoted by the companies that make and sell them.</p> <p>The <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6419242/">complementary and alternative medicines</a> women often try for menopausal symptoms include phytoestrogens, wild yam, dong quai, ginseng and black cohosh.</p> <p>Black cohosh (plant name <em>Cimicifuga racemosa</em>) was <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">traditionally</a> used by Native Americans to treat a variety of health concerns such as sore throat, kidney trouble, musculoskeletal pain and menstrual problems. It is now a popular herbal choice for hot flushes and night sweats, as well as vaginal dryness and mood changes.</p> <p>There are <a href="https://pubmed.ncbi.nlm.nih.gov/37252752/">many theories</a> for how the active ingredients in black cohosh might work in the body, such as acting like oestrogen, or affecting chemical pathways in the brain. But despite extensive research, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">evidence to support these theories remains inconclusive</a>.</p> <p>It is also not clear whether black cohosh is effective for hot flushes. Results from individual studies are mixed, with <a href="https://pubmed.ncbi.nlm.nih.gov/17565936/">some</a> finding black cohosh improves hot flushes, while <a href="https://pubmed.ncbi.nlm.nih.gov/18257142/">others</a> have found it doesn’t.</p> <p>A 2012 <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">review</a> combined all the results from studies of menopausal women using black cohosh to that date and found overall there was no proof black cohosh reduces hot flushes more effectively than an inactive treatment (placebo). <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">This review</a> also revealed that many studies did not use rigorous research methods, so the findings are hard to interpret.</p> <p>A more recent <a href="https://pubmed.ncbi.nlm.nih.gov/33021111/">review</a> of clinical trials claimed black cohosh may ease menopausal symptoms, but the included studies were mostly small, less than six months long, and included women with mild symptoms.</p> <p>There is also no meaningful evidence black cohosh helps other symptoms of menopause, such as vaginal symptoms, sexual problems, or poor general wellbeing, or that it protects against bone loss.</p> <p>Evidence for how black cohosh is absorbed and metabolised by the body is also lacking, and it is not known what dose or formulation is best to use.</p> <p>More good quality studies are needed to decide whether black cohosh works for hot flushes and other menopausal symptoms.</p> <h2>Is it safe to try?</h2> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/33021111/">review of studies</a> suggests black cohosh is safe to use, although many of the studies have not reported possible adverse reactions in detail. Side effects such as gastrointestinal upset and rashes may occur.</p> <p>While there have been <a href="https://www.mja.com.au/journal/2008/188/7/liver-failure-associated-use-black-cohosh-menopausal-symptoms#0_i1091948">rare reports of liver damage</a>, there is <a href="https://pubmed.ncbi.nlm.nih.gov/21228727/">no clear evidence</a> black cohosh was the cause. Even so, in Australia, black cohosh manufacturers and suppliers are required to put a warning label for the potential of harm to the liver on their products.</p> <p>It is recommended black cohosh is not used by women with menopausal symptoms <a href="https://www.canceraustralia.gov.au/cancer-types/breast-cancer/impacted-by-breast-cancer/physical-changes/menopause/treatments-menopausal-symptoms">after breast cancer</a>, as its safety after breast cancer is uncertain. All women should consult with their doctor before using black cohosh if they are taking other medications in case of possible drug interactions.</p> <p>Many women like to try herbal therapies for hot flushes and other menopausal symptoms. While black cohosh is generally considered safe and some women may find it helps them, at the moment there is not enough scientific evidence to show its effects are any better than placebo.</p> <p>Women experiencing troublesome menopausal symptoms, such as hot flushes, should talk to their doctor about the best treatment options for them.<!-- Below is The Conversation's page counter tag.

"It's been a great privilege": Eddie McGuire delivers sad Millionaire Hot Seat news

<p>Veteran host Eddie McGuire has announced that <em>Millionaire Hot Seat</em> will be taking a break at the end of January 2024.</p> <p>During a broadcast on 3AW, McGuire expressed both pride and sadness as he conveyed his gratitude to fans for their unwavering support over the years. McGuire revealed that a new show would be introduced in place of Millionaire Hot Seat at 5 o'clock on the Nine network after the 25th-anniversary milestone is reached in 2024.</p> <p>"It's with great pride and joy and also sadness that I announce this morning that Millionaire Hot Seat will go into hiatus at the end of January next year," McGuire announced. "We will finish off this year and there'll be a replacement show at five 'clock on the Nine network after we hit our 25th anniversary when we go into 2024.</p> <p>"I've had the privilege of being in everybody's lounge room for a long time every night at 5 o'clock and I love the fact that so many people come and say, 'I sit there with my grandparents and we did these things together'. It's been a great privilege."</p> <p>Reflecting on the show's impact, McGuire highlighted its multicultural appeal and the moments of personal significance shared by contestants. He recounted the touching story of a contestant who won $250,000 during the global financial crisis, and how the prize money was life-saving for him, preventing him from having to sell his house.</p> <p>Since its debut on April 20, 2009, <em>Millionaire Hot Seat</em> has become Australia's longest-running quiz show and the sole program in the country where contestants have the chance to win $1 million.

"I can’t a fjord it": Inside one of the world’s most extreme restaurants

<p>One of the world's most extreme restaurants has gone viral and not only for its unique location and shape, but also its exclusive dining experience that's eerily similar to 2022 horror film <em>The Menu</em>.</p> <p>Restaurant Iris is located inside a giant silvery orb in Hardangerfjord, the second largest Fjord in Norway.</p> <p>The four-storey structure, called the Salmon Eye is inspired by - you guessed it - the shape of a fish eye, and it is quite a sight to behold. </p> <p>The Salmon Eye is covered in 9,000 steel plates to emulate fish scales, weighing a whopping 1,256 tonnes and an impressive diameter of 25 metres, with one sub-surface floor that boasts a panoramic view of the Fjord. </p> <p>The restaurant itself can only be accessed by an electric boat off the shore of Rosendal, as guests are treated to "an exclusive expedition dining-journey" which offers an 18-course meal and panoramic views. </p> <p>The 24-seat restaurant is run by Head Chef Anika Madsen, and prior to having their main meal, guests are taken to the chef's boathouse on the nearby island of Snilstveitoy, for a "welcoming snack". </p> <p>The menu is designed to showcase "the most local ingredients possible", which reflects Madsen's "commitment to sustainability" and her "<span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">passion for discovering new ingredients from the ocean". </span></p> <p>Mari Eriksmoen posted the viral video on TikTok which has racked up over eight million views. </p> <p>"This spectacular just opened in the middle of the Hardangerfjord in Norway," she started in the clip with a shot of the structure floating in the middle of the fjord. </p> <p>She described the experience of walking into the restaurant "like entering a spaceship," and was mesmerised by the "insane views". </p> <p>Once the evening kicks off, guests indulge in a multi-sensory experience where they were instructed to pick a "cracker" hanging from the ceiling after watching a "short movie about food waste". </p> <p>Another TikTok user compared it to the <span style="background-color: #ffffff; font-family: graphik, Arial, sans-serif; font-size: 16px; letter-spacing: -0.16px;">extraterrestrial spacecraft </span><span style="background-color: #ffffff; font-family: graphik, Arial, sans-serif; font-size: 16px; letter-spacing: -0.16px;">from the 2016 sci-fi film <em>Arrival</em>.</span></p> <p>However many other users compared the dining experience to 2022 horror film <em>The Menu</em>, where a group of guests eat at an exclusive restaurant on a remote island and face dire consequences. </p> <p>"Did we learn nothing from The Menu?" commented one user with the crying face emoji. </p> <p>"I know how this movie ends," wrote another user. </p> <p>"I can’t a fjord it," joked a third. </p> <p>The dining experience aims to "blend gastronomy and activism on a global scale" as they hope to raise awareness on the the challenges and threats to the global food system. </p> <p>"The menu at Iris reads like a story, " a statement said. </p> <p>"A story about the challenges and threats to the global food system, but also with ideas and suggestions for future innovations, that can help bring us closer to solving them." </p> <p>The tasting menu itself is priced at 3,200 Norwegian Krone ($316) with an optional wine pairing for 2,500 Norwegian Krone ($247). </p> <p>For those who want to visit the Salmon Eye, but don't want to dine in, they can buy a ticket for a  two-hour "learning experience" at the centre priced at 349 Norwegian Krone ($34). </p> <p><em>Images: Salmon Eye Website/ Instagram, TikTok</em></p>

Taking an antidepressant? Mixing it with other medicines – including some cold and flu treatments – can be dangerous

<p><em><a href="https://theconversation.com/profiles/treasure-mcguire-135225">Treasure McGuire</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>In the depths of winter we are more at risk of succumbing to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7522168/">viral respiratory infections</a> – from annoying sore throat, common cold and sinusitis, to the current resurgence of respiratory syncytial virus (RSV), influenza and COVID.</p> <p>Symptoms of upper respiratory tract infection range in severity. They can include fever, chills, muscle or body aches, cough, sore throat, runny or stuffy nose, earache, headache, and fatigue. Most antibiotics target bacteria so are <a href="https://pubmed.ncbi.nlm.nih.gov/32495003/">not effective</a> for viral infections. Many people seek relief with over-the-counter medicines.</p> <p>While evidence varies, guidelines suggest medicines taken by mouth (such as cough syrups or cold and flu tablets) have a <a href="https://pubmed.ncbi.nlm.nih.gov/25420096/">limited but potentially positive</a> short-term role for managing upper respiratory infection symptoms in adults and children older than 12. These include:</p> <ul> <li>paracetamol or ibuprofen for pain or fever</li> <li>decongestants such as phenylephrine or pseudoephedrine</li> <li>expectorants and mucolytics to thin and clear mucus from upper airways</li> <li>dry cough suppressants such as dextromethorphan</li> <li>sedating or non-sedating antihistamines for runny noses or watery eyes.</li> </ul> <p>But what if you have been prescribed an antidepressant? What do you need to know before going to the pharmacy for respiratory relief?</p> <h2>Avoiding harm</h2> <p>An audit of more than 5,000 cough-and-cold consumer enquiries to an Australian national medicine call centre found questions frequently related to drug-drug interactions (29%). An 18-month analysis showed 20% of calls <a href="https://pubmed.ncbi.nlm.nih.gov/26590496/">concerned</a> potentially significant interactions, particularly with antidepressants.</p> <p>Australia remains in the “<a href="https://www.aihw.gov.au/mental-health/topic-areas/mental-health-%20prescriptions#Prescriptionsbytype">top ten</a>” antidepressant users in the <a href="https://stats.oecd.org/Index.aspx?DataSetCode=HEALTH_PHMC">OECD</a>. More than <a href="https://www.aihw.gov.au/mental-health/topic-areas/mental-health-prescriptions">32 million</a> antidepressant prescriptions are dispensed on the Pharmaceutical Benefits Scheme each year.</p> <p>Antidepressants are commonly prescribed to manage symptoms of anxiety or depression but are also used in chronic pain and incontinence. They are classified primarily by how they affect chemical messengers in the nervous system.</p> <p>These classes are:</p> <ul> <li><strong>selective serotonin reuptake inhibitors (SSRI)</strong> such as fluoxetine, escitalopram, paroxetine and sertraline</li> <li><strong>serotonin and noradrenaline reuptake inhibitors (SNRI)</strong> such as desvenlafaxine, duloxetine and venlafaxine</li> <li><strong>tricyclic antidepressants (TCA)</strong> such as amitriptyline, doxepin and imipramine</li> <li><strong>monoamine oxidase inhibitors (MAOI)</strong> such as tranylcypromine</li> <li><strong>atypical medicines</strong> such as agomelatine, mianserin, mirtazapine, moclobemide, reboxetine and vortioxetine</li> <li><strong>complementary medicines</strong> including St John’s wort, S-adenosyl methionine (SAMe) and L-tryptophan</li> </ul> <p>Medicines within the same class of antidepressants have similar actions and side-effect profiles. But the molecular differences of individual antidepressants mean they may have different interactions with medicines taken at the same time.</p> <h2>Types of drug interactions</h2> <p>Drug interactions can be:</p> <ul> <li><strong>pharmacokinetic</strong> – what the body does to a drug as it moves into, through and out of the body. When drugs are taken together, one may affect the absorption, distribution, metabolism or elimination of the other</li> <li><strong>pharmacodynamic</strong> – what a drug does to the body. When drugs are taken together, one may affect the action of the other. Two drugs that independently cause sedation, for example, may result in excessive drowsiness if taken together.</li> </ul> <p>There are many <a href="https://wchh.onlinelibrary.wiley.com/doi/pdf/10.1002/pnp.429">potential interactions</a> between medications and antidepressants. These include interactions between over-the-counter medicines for upper respiratory symptoms and antidepressants, especially those taken orally.</p> <p>Concentrations of nasal sprays or inhaled medicines are generally lower in the blood stream. That means they are less likely to interact with other medicines.</p> <h2>What to watch for</h2> <p>It’s important to get advice from a pharmacist before taking any medications on top of your antidepressant.</p> <p>Two symptoms antidepressant users should monitor for shortly after commencing a cough or cold medicine are central nervous system effects (irritability, insomnia or drowsiness) and effects on blood pressure.</p> <p>For example, taking a selective SSRI antidepressant and an oral decongestant (such as pseudoephedrine or phenylephrine) can cause irritability, insomnia and affect blood pressure.</p> <p>Serotonin is a potent chemical compound produced naturally for brain and nerve function that can also constrict blood vessels. Medicines that affect serotonin are common and include most antidepressant classes, but also decongestants, dextromethorphan, St John’s wort, L-tryptophan, antimigraine agents, diet pills and amphetamines.</p> <p><a href="https://reference.medscape.com/drug-interactionchecker">Combining drugs</a> such as antidepressants and decongestants that both elevate serotonin levels can cause irritability, headache, insomnia, diarrhoea and blood pressure effects – usually increased blood pressure. But some people experience orthostatic hypotension (low blood pressure on standing up) and dizziness.</p> <p>For example, taking both a serotonin and SNRI antidepressant and dextromethorphan (a cough suppressant) can add up to high serotonin levels. This can also occur with a combination of the complementary medicine St John’s Wort and an oral decongestant.</p> <p>Where serotonin levels are too high, <a href="https://pubmed.ncbi.nlm.nih.gov/15666281/">severe symptoms</a> such as confusion, muscle rigidity, fever, seizures and even death have been reported. Such symptoms are rare but if you notice any of these you should stop taking the cold and flu medication straight away and seek medical attention.</p> <h2>Ways to avoid antidepressant drug interactions</h2> <p>There are a few things we can do to prevent potentially dangerous interactions between antidepressants and cold and flu treatments.</p> <p><strong>1. Better information</strong></p> <p>Firstly, there should be more targeted, consumer-friendly, <a href="https://www.webmd.com/interaction-checker/default.htm">online drug interaction information</a> available for antidepressant users.</p> <p><strong>2. Prevent the spread of viral infections as much as possible</strong></p> <p>Use the non-drug strategies that have worked well for COVID: regular hand washing, good personal hygiene, social distancing, and facemasks. Ensure adults and children are up to date with immunisations.</p> <p><strong>3. Avoid potential drug interactions with strategies to safely manage symptoms</strong></p> <p>Consult your pharmacist for strategies most appropriate for you and only use cold and flu medications while symptoms persist:</p> <ul> <li>treat muscle aches, pain, or a raised temperature with analgesics such as paracetamol or ibuprofen</li> <li>relieve congestion with a nasal spray decongestant</li> <li>clear mucus from upper airways with expectorants or mucolytics</li> <li>dry up a runny nose or watery eyes with a non-sedating antihistamine.</li> </ul> <p>Avoid over-the-counter cough suppressants for an irritating dry cough. Use a simple alternative such as honey, steam inhalation with a few drops of eucalyptus oil or a non-medicated lozenge instead.</p> <p><strong>4. Ask whether your symptoms could be more than the common cold</strong></p> <p>Could it be influenza or COVID? Seek medical attention if you are concerned or your symptoms are not improving. <!-- Below is The Conversation's page counter tag.

What happens in our body when we encounter and fight off a virus like the flu, SARS-CoV-2 or RSV?

<p><em><a href="https://theconversation.com/profiles/lara-herrero-1166059">Lara Herrero</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> and <a href="https://theconversation.com/profiles/wesley-freppel-1408971">Wesley Freppel</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p><a href="https://www.labcorp.com/coronavirus-disease-covid-19/covid-news-education/covid-19-vs-flu-vs-rsv-how-tell-difference">Respiratory viruses</a> like influenza virus (flu), SARS-CoV-2 (which causes COVID) and respiratory syncytial virus (RSV) can make us sick by infecting our respiratory system, including the nose, upper airways and lungs.</p> <p>They spread from person to person through respiratory droplets when someone coughs, sneezes, or talks and can cause death in serious cases.</p> <p>But what happens in our body when we first encounter these viruses? Our immune system uses a number of strategies to fight off viral infections. Let’s look at how it does this.</p> <h2>First line of defence</h2> <p>When we encounter respiratory viruses, the <a href="https://www.sciencedirect.com/science/article/pii/S193131281600038X?via%3Dihub/">first line of defence</a> is the physical and chemical barriers in our nose, upper airways, and lungs. Barriers like the mucus lining and hair-like structures on the surface of cells, work together to trap and remove viruses before they can reach deeper into our respiratory system.</p> <p>Our defence also includes our behaviours such as coughing or sneezing. When we blow our nose, the mucus, viruses, and any other pathogens that are caught within it are expelled.</p> <p>But sometimes, viruses manage to evade these initial barriers and sneak into our respiratory system. This activates the cells of our innate immune system.</p> <h2>Patrolling for potential invaders</h2> <p>While our acquired immune system develops over time, our innate immune system is present at birth. It generates “non-specific” immunity by identifying what’s foreign. The cells of innate immunity act like a patrol system, searching for any invaders. These innate cells patrol almost every part of our body, from our skin to our nose, lungs and even internal organs.</p> <p>Our respiratory system has different type of innate cells such – as macrophages, neutrophils and natural killer cells – which patrol in our body looking for intruders. If they recognise anything foreign, in this case a virus, they will initiate an attack response.</p> <p>Each cell type plays a slightly different role. Macrophages, for example, will not only engulf and digest viruses (phagocytosis) but also release a cocktail of different molecules (cytokines) that will warn and recruit other cells to <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/cmi.12580">fight against the danger</a>.</p> <p>In the meantime, natural killer cells, aptly named, attack infected cells, and stop viruses from multiplying and <a href="https://www.nature.com/articles/s41577-021-00558-3">invading our body further</a>.</p> <p>Natural killer cells also promote inflammation, a <a href="https://www.hindawi.com/journals/jir/2018/1467538/">crucial part of the immune response</a>. It helps to recruit more immune cells to the site of infection, enhances blood flow, and increases the permeability of blood vessels, allowing immune cells to reach the infected tissues. At this stage, our immune system is fighting a war against viruses and the result can cause inflammation, fevers, coughs and congestion.</p> <h2>Launching a specific attack</h2> <p>As the innate immune response begins, another branch of the immune system called the adaptive immune system is <a href="https://www.ncbi.nlm.nih.gov/books/NBK21070/">activated</a>.</p> <p>The adaptive immune system is more specific than the innate immune system, and it decides on the correct tools and strategy to fight off the viral invaders. This system plays a vital role in eliminating the virus and providing long-term protection against future infections.</p> <p>Specialised cells called T cells and B cells are key players in acquired immunity.</p> <p>T cells (specifically, helper T cells and cytotoxic T cells) recognise viral proteins on the surface of infected cells:</p> <ul> <li> <p>helper T cells release molecules that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764486/">further activate immune cells</a></p> </li> <li> <p>cytotoxic T cells directly kill infected cells with a very great precision, <a href="https://www.frontiersin.org/articles/10.3389/fimmu.2018.00678/full">avoiding any healthy cells around</a>.</p> </li> </ul> <p>B cells produce antibodies, which are proteins that can bind to viruses, neutralise them, and mark them for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7247032/">destruction by other immune cells</a>.</p> <p>B cells are a critical part of memory in our immune system. They will remember what happened and won’t forget for years. When the same virus attacks again, B cells will be ready to fight it off and will neutralise it faster and better.</p> <p>Thanks to the adaptive immune system, vaccines for respiratory viruses such as the COVID mRNA vaccine keep us protected from <a href="https://www.health.gov.au/our-work/covid-19-vaccines/our-vaccines/how-they-work">being sick or severely ill</a>. However, if the same virus became mutated, our immune system will act as if it was a new virus and will have to fight in a war again.</p> <h2>Neutralising the threat</h2> <p>As the immune response progresses, the combined efforts of the innate and adaptive immune systems helps control the virus. Infected cells are cleared, and the virus is neutralised and eliminated from the body.</p> <p>As the infection subsides, symptoms gradually improve, and we begin to feel better and to recover.</p> <p>But recovery varies depending on the specific virus and us as individuals. Some respiratory viruses, like rhinoviruses which cause the common cold, may cause relatively mild symptoms and a quick recovery. Others, like the flu, SARS-CoV-2 or severe cases of RSV, may lead to more severe symptoms and a longer recovery time.</p> <p>Some viruses are very strong and too fast sometimes so that our immune system does not have the time to develop a proper immune response to fight them off. <!-- Below is The Conversation's page counter tag.

It’s official: Australia is set for a hot, dry El Niño. Here’s what that means for our flammable continent

<p><em><a href="https://theconversation.com/profiles/kevin-tolhurst-am-184">Kevin Tolhurst AM</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>An El Niño event has <a href="https://public.wmo.int/en/media/press-release/world-meteorological-organization-declares-onset-of-el-ni%C3%B1o-conditions">arrived</a>, according to the World Meteorological Organization, raising fears of record high global temperatures, extreme weather and, in Australia, a severe fire season.</p> <p>The El Niño is a reminder that bushfires are part of Australian life – especially as human-caused global warming worsens. But there are a few important considerations to note.</p> <p>First, <a href="http://www.bom.gov.au/climate/updates/articles/a008-el-nino-and-australia.shtml">not all</a> El Niño years result in bad bushfires. The presence of an El Niño is only one factor that determines the prevalence of bushfires. Other factors, such as the presence of drought, also come into play.</p> <p>And second, whether or not this fire season is a bad one, Australia must find a more sustainable and effective way to manage bushfires. The El Niño threat only makes the task more urgent.</p> <h2>Understanding fire in Australia</h2> <p>An El Niño is <a href="https://www.climate.gov/news-features/blogs/june-2023-enso-update-el-ni%C3%B1o-here">declared</a> when the sea surface temperature in large parts of the tropical Pacific Ocean warms significantly.</p> <p>The <a href="https://public.wmo.int/en/media/press-release/world-meteorological-organization-declares-onset-of-el-ni%C3%B1o-conditions">statement</a> by the World Meteorological Organization, released on Tuesday, said El Niño conditions have developed in the tropical Pacific for the first time in seven years “setting the stage for a likely surge in global temperatures and disruptive weather and climate patterns”.</p> <p>The organisation says there’s a 90% probability of the El Niño event continuing during the second half of 2023. It said El Niño can trigger extreme heat and also cause severe droughts over Australia and other parts of the world.</p> <p>But before we start planning ahead for the next bushfire season, it’s important to understand what drives bushfire risks – and the influence of climate change, fire management and events such as El Niño.</p> <p>The evidence for human-induced climate change is <a href="https://www.ipcc.ch/report/sixth-assessment-report-cycle/">irrefutable</a>. While the global climate has changed significantly <a href="https://theconversation.com/while-we-fixate-on-coronavirus-earth-is-hurtling-towards-a-catastrophe-worse-than-the-dinosaur-extinction-130869">in the past</a>, the current changes are occurring at an unprecedented rate.</p> <p>In geologic time scales, before the influence of humans, a significant <a href="https://publications.csiro.au/rpr/pub?list=BRO&amp;pid=procite:13c02405-e8c6-466c-a400-f6137710a651">shift</a> in climate has been <a href="https://www.publish.csiro.au/book/6836/">associated</a> with an increase in fire activity in Australia. There is every reason to expect fire activity will increase with human-induced climate change as well.</p> <p>Humans have also changed the Australian fire landscape – both First Nations people and, for the past 200 years, European colonisers.</p> <p>Changes brought about by Indigenous Australians were widespread, but <a href="https://pubmed.ncbi.nlm.nih.gov/32378038/">sustainable</a>. Their methods included, for example, lighting “cool” fires in small, targeted patches early in the dry season. This reduced the chance that very large and intense fires would develop.</p> <p>Changes brought about by European colonisers have also been widespread – such as land clearing using fire, and fire suppression to protect human life and property. But this approach has been <a href="https://www.researchgate.net/publication/30388718_National_Inquiry_on_Bushfire_Mitigation_and_Management">far from sustainable</a>, either financially, ecologically or socially.</p> <p>Australia has just experienced a period of high rainfall across the continent due to a La Niña event <a href="https://climateextremes.org.au/large-scale-climate-drivers-in-australia-2022/#:%7E:text=The%20combined%20influence%20of%20a,in%20123%20years%20of%20records.">combined with</a> two other climate drivers: a negative Indian Ocean Dipole and a positive Southern Annular Mode. It means the soil is moist and plants are flourishing.</p> <p>Now, we’re set to enter into a drying period driven by an El Niño. The abundant plant growth leading into a dry period is likely to result in widespread bushfires across Australia.</p> <p>Initially, this is <a href="https://knowledge.aidr.org.au/resources/bushfire-new-south-wales-1974/">likely to occur</a> in semi-arid inland areas where grasses have flourished in the wet period, but will dry out quickly. If the drying cycle persists for two or three years, then fires might become more prevalent in forests and woodlands in temperate Australia.</p> <p>But an El Niño year doesn’t necessarily mean a bad bushfire season is certain.</p> <p>In Australia, El Niño events are associated with hotter and drier conditions, <a href="https://www.researchgate.net/publication/263018552_Multi-decadal_variability_of_forest_fire_risk_-_Eastern_Australia">leading to more days</a> of high fire danger. But large and severe forest fires also need a prolonged drought to dry out fuels, especially in sheltered gullies and slopes. Soils and woody vegetation are currently moist following the La Niña period.</p> <p>So El Niño and its opposite phase, La Niña, are on their own are a relatively <a href="https://research.monash.edu/en/publications/forecasting-fire-activity-in-victoria-australia-using-antecedent-">poor predictor</a> of the number and size of bushfires.</p> <h2>Fight smarter, and be prepared</h2> <p>Climate change will continue to test our fire management systems. And the return of an El Niño has fire crews <a href="https://www.theguardian.com/environment/2023/jun/10/australia-firefighters-fire-crews-prepare-for-return-of-el-nino-bushfire-season-smoke-hazard-reduction-burns">on alert</a>.</p> <p>When it comes to fire management, Australia must be much smarter than it has been for the past 200 years. This means changing the focus to holistic fire management. Throwing huge amounts of money and resources at controlling bushfires – such as <a href="https://www.canberratimes.com.au/story/7034300/govt-vows-to-get-more-firefighting-aircraft/">purchasing more</a> and larger <a href="https://www.news.com.au/technology/environment/new-weapon-to-fight-aussie-bushfires-kicks-off-service-in-wa/news-story/fa66e567e336164723cae8b98bb3ba8d">firefighting aircraft</a> – is is not sustainable or sensible.</p> <p>Fire is as fundamental to our environment as wind and rain. And the amount of energy released from a large bushfire will never be matched by any level of resources humans can muster.</p> <p>The evidence bears this out. Take, for example, <a href="https://www.publish.csiro.au/wf/WF9970221">analysis</a> of fire dynamics in two areas north and south of the US-Mexico border. Between 1920 and 1972, authorities on the US side had spent hundreds of millions of dollars on firefighting aircraft and other resources trying to suppress wildfires. This resulted in fewer wildfires than in the Mexico region. But the fires that occurred were larger and more severe.</p> <p>Similar patterns have occurred in Australia. For example, a <a href="https://www.researchgate.net/publication/284776990_Evidence_of_altered_fire_regimes_in_the_Western_Desert_regime_of_Australia">study</a> of burn patterns in the Western Desert region showed that after the exodus of Traditional Owners, the number of fires reduced substantially, but the fires became far bigger.</p> <h2>Change must happen</h2> <p>Damaging bushfires will return to Australia in the near future. The expected return of another El Niño should heighten efforts to create a more considered and sustainable fire management regime – particularly in southern Australia.</p> <p>Experts, including me, have <a href="https://www.forestry.org.au/wp-content/uploads/2022/11/Final-KPI-Document-v2.pdf">devised</a> <a href="https://knowledge.aidr.org.au/media/4935/nationalbushfiremanagementpolicy_2014.pdf">plans</a> to guide the shift. They include:</p> <ul> <li>effectively managing the land with fire, including promoting Indigenous Australians’ use of fire</li> <li>engaging communities in bushfire mitigation and management</li> <li>better coordination across land, fire and emergency management agencies</li> <li>ensuring fire management is based on “best practice” approaches.</li> </ul> <p>Australia, with its wealth of scientific knowledge and long history of Indigenous land management, should be well placed to manage fire sustainably – even with the pressures of climate change. Changing our approach will not be quick or simple, but it must be done.<!-- Below is The Conversation's page counter tag.

6 habits of people who don’t get sick

<p>Winter is a dangerous time. Although cold temperatures themselves don’t cause us to get sick, our winter habits invite the spread of germs and risk of contagion is high.</p> <p>If you find yourself sick every winter, here are some useful habits of those healthy people to take up.</p> <p><strong>1. They get enough sleep</strong></p> <p>It’s easy to experience disrupted sleep during winter. When air is too cold, it will negatively affect melatonin production and cause the body's sleep cycle to be disrupted. However, research shows that people who sleep only five to six hours a night have a 30 per cent chance of catching a cold when exposed to the virus; those who get more than seven hours reduce their risk to 17 per cent.</p> <p><strong>2. They pay extra attention to hygiene</strong></p> <p>With more germs in the air, now is the time to stay conscious about where they may be festering. Key areas include bathroom door handles, taps, fridges, elevator buttons and public transport. Keep antibacterial wipes on you so whenever you touch a high risk surface, you can cleanse you hand before eating, or touching your face and eyes.</p> <p><strong>3. They exercise regularly</strong></p> <p>Winter is notorious for zapping our work-out motivation. However, exercise strengthens the immune system and makes you less likely to catch upper respiratory infections.</p> <p><strong>4. The get their flu shot</strong></p> <p>Flu shots, approved for all adults, are effective 50 to 60 per cent of the time in preventing the flu and may also reduce the severity of symptoms.</p> <p><strong>5. They don’t smoke</strong></p> <p>Cigarette smoke appears to damage the mucus membranes, which act as the frontline barrier to infectious agents, making smokers twice as likely to catch a cold and several times more likely to develop the flu.</p> <p><strong>6. They enjoy a drink</strong></p> <p>Harvard University School of Public Health researchers found that red wine was particularly protective against colds, probably due to the anti-inflammatory action of the phenol, resveratrol. Just keep in mind that drinking more than two glasses a day raises the risk for infections.</p> <p><em>Image credit: Shutterstock</em></p>

Why is it so damn cold right now? A weather researcher explains

<p><em><a href="https://theconversation.com/profiles/tess-parker-111039">Tess Parker</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>If you woke up this morning and thought “Gosh, it’s a bit brisk!”, you’re not alone.</p> <p>Temperatures plummeted across southeast Australia this week, with Weatherzone <a href="https://www.weatherzone.com.au/news/coldest-morning-in-5-years-for-parts-of-nsw-qld-act/1342232">reporting</a> Canberra’s low of -7.2ºC was “its lowest temperature since 2018 and the lowest for June since 1986.”</p> <p>Sydney experienced its <a href="https://www.weatherzone.com.au/news/coldest-morning-in-5-years-for-parts-of-nsw-qld-act/1342232">coldest June morning</a> today since 2010, with a temperature of 5.2ºC. In Victoria, temperatures of -7.2ºC were <a href="https://www.weatherzone.com.au/news/coldest-morning-in-5-years-for-parts-of-nsw-qld-act/1342232">recorded</a>.</p> <p>So what’s going on? Here’s what you need to know.</p> <h2>A big pool of Antarctic air</h2> <p>It started off at the beginning of the week, when a low-pressure system saw a big cold front come through southeastern Australia on Sunday night. This basically means a lot of very cold air came from higher latitudes close to Antarctica, and swept across southeastern Australia.</p> <p>So everywhere from Melbourne to Sydney to South Australia was getting this big pool of incredibly cold air at the start of the week.</p> <p>Even though that cold front has now moved off over the Tasman Sea, it has left behind it a really big high-pressure system sitting over the southeast of Australia.</p> <p>This has led to calm conditions, where winds are very light and the skies are clear with not a lot of cloud during the day or night.</p> <p>So it’s getting really, really cold in the early mornings because there are no clouds to act as an insulating blanket for the Earth and trap the heat that the planet radiates to space overnight.</p> <p>The result, in many places, has been very cold temperatures before sunrise, often with a lot of frost.</p> <h2>Remind me, what’s a low-pressure system? And what’s a high-pressure system?</h2> <p>The air above the Earth’s surface has mass, but it’s not uniform everywhere. The way the atmosphere is moved around by what’s going on at upper levels will mean the mass of the atmosphere is redistributed. That transmits down to the surface where we live and causes low- and high-pressure systems.</p> <p>At some points the pressure is lower because there’s not as much mass of air above that point over the Earth. This is what we call a low-pressure system. Air rises in a low, reducing the pressure at the surface.</p> <p>The winds around the low are clockwise in the Southern Hemisphere. So when that low is approaching Australia, the winds on the western side are bringing air from near Antarctica. That’s why a low-pressure system in Australia often means cooler conditions.</p> <p>At some points above the Earth, the pressure is higher because the mass of air above that area is greater. This is what we call a high-pressure system. Air descends in a high, raising the surface pressure.</p> <p>High-pressure systems tend to mean very calm weather; the wind isn’t very strong, the skies tend to be clear and there’s little to no cloud.</p> <p>In summer, that means the sun is baking down all day onto Earth with no protection from cloud. So a high-pressure system in summer can mean a heatwave.</p> <p>In winter, the lack of cloud in a high-pressure system means that much of the heat the Earth has absorbed during the day just re-radiates out to space again, as the cloud isn’t there to act as a blanket and keep all that heat in.</p> <p>That’s why a high-pressure system can mean very cold weather in winter, especially when there are lower levels of sunlight coming in to warm up the Earth in the first place.<!-- Below is The Conversation's page counter tag.
