Better sleep is a protective factor against dementia

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, <a href="https://theconversation.com/institutions/monash-university-1065"><em>Monash University</em></a></em></p> <p>Dementia is a progressive loss of cognitive abilities, such as memory, that is significant enough to have an impact on a person’s daily activities.</p> <p>It can be caused by a number of different diseases, including <a href="https://alzheimer.ca/en/about-dementia/what-alzheimers-disease">Alzheimer’s</a>, which is the most common form. Dementia is caused by a loss of neurons over a long period of time. Since, by the time symptoms appear, many changes in the brain have already occurred, many scientists are focusing on studying the risk and protective factors for dementia.</p> <p>A risk factor, or conversely, a protective factor, is a condition or behaviour that increases or reduces the risk of developing a disease, but does not guarantee either outcome. Some risk factors for Alzheimer’s disease and dementia, such as age or genetics, are not modifiable, but there are several other factors we can influence, <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">specifically lifestyle habits and their impact on our overall health</a>.</p> <p>These risk factors include depression, lack of physical activity, social isolation, high blood pressure, obesity, diabetes, excessive alcohol consumption and smoking, as well as poor sleep.</p> <p>We have been focusing our research on the question of sleep for over 10 years, particularly in the context of the <a href="https://www.nhlbi.nih.gov/science/framingham-heart-study-fhs">Framingham Heart Study</a>. In this large community-based cohort study, ongoing since the 1940s, the health of surviving participants has been monitored to the present day. As researchers in sleep medicine and epidemiology, we have expertise in researching the role of sleep and sleep disorders in cognitive and psychiatric brain aging.</p> <p>As part of our research, we monitored and analyzed the sleep of people aged 60 and over to see who did — or did not — develop dementia.</p> <h2>Sleep as a risk or protective factor against dementia</h2> <p>Sleep appears to play an essential role in a number of brain functions, such as memory. Good quality sleep <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2793873">could therefore play a vital role in preventing dementia</a>.</p> <p>Sleep is important for maintaining <a href="https://www.science.org/doi/10.1126/science.1241224">good connections in the brain</a>. Recently, research has revealed that sleep seems to have a function similar to that of a garbage truck for the brain: <a href="https://doi.org/10.1016/j.mad.2023.111899">deep sleep could be crucial for eliminating metabolic waste from the brain</a>, including clearing certain proteins, such as those known to accumulate in the brains of people with Alzheimer’s disease.</p> <p>However, the links between deep sleep and dementia still have to be clarified.</p> <h2>What is deep sleep?</h2> <p>During a night’s sleep, we go through several <a href="http://ceams-carsm.ca/en/a-propos-du-sommeil/">sleep stages</a> that succeed one another and are repeated.</p> <p>NREM sleep (non-rapid eye movement sleep) is divided into light NREM sleep (NREM1 stage), NREM sleep (NREM2 stage) and deep NREM sleep, also called slow-wave sleep (NREM3 stage). The latter is associated with several restorative functions. Next, REM sleep (rapid eye movement sleep) is the stage generally associated with the most vivid dreams. An adult generally spends around 15 to 20 per cent of each night in deep sleep, if we add up all the periods of NREM3 sleep.</p> <p>Several sleep changes are common in adults, such as going to bed and waking up earlier, sleeping for shorter periods of time and less deeply, and waking up more frequently during the night.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=279&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=279&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=279&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=350&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=350&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=350&fit=crop&dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Sleep stages, and the role of deep sleep for brain health.</span> <span class="attribution"><span class="source">(Andrée-Ann Baril)</span></span></figcaption></figure> <h2>Loss of deep sleep linked to dementia</h2> <p>Participants in the <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2810957">Framingham Heart Study</a> were assessed using a sleep recording — known as polysomnography — on two occasions, approximately five years apart, in 1995-1998 and again in 2001-2003.</p> <p>Many people showed a reduction in their deep slow-wave sleep over the years, as is to be expected with aging. Conversely, the amount of deep sleep in some people remained stable or even increased.</p> <p>Our team of researchers from the Framingham Heart Study followed 346 participants aged 60 and over for a further 17 years to observe who developed dementia and who did not.</p> <p>Progressive loss of deep sleep over time was associated with an increased risk of dementia, whatever the cause, and particularly Alzheimer’s type dementia. These results were independent of many other risk factors for dementia.</p> <p>Although our results do not prove that loss of deep sleep causes dementia, they do suggest that it could be a risk factor in the elderly.

Encouraging sleep with good lifestyle habits could have the potential to help us age in a healthier way.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222854/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, Professeure-chercheure adjointe au Département de médecine, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, Associate Professor of Neurology and Epidemiology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Could not getting enough sleep increase your risk of type 2 diabetes?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936"><em>University of Technology Sydney</em></a></em></p> <p>Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes.</p> <p>So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex.</p> <h2>The study</h2> <p>Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade.</p> <p>The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk.</p> <p>As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets.</p> <p>Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category.</p> <p>The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours.</p> <p>One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less.</p> <p>Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations.</p> <h2>Why might short sleep increase diabetes risk?</h2> <p>In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body.</p> <p>We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes.</p> <p>Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>.</p> <p>This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses.</p> <p>These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours.</p> <p>While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes.</p> <p>Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase.</p> <p>The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>.</p> <h2>Good sleep, healthy diet</h2> <p>Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes.</p> <p>Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle.</p> <p>While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health.</p> <p>The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk.</p> <p>In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The unique travel hack that is guaranteed to help beat jet lag

<p dir="ltr">Experts have revealed how to beat jet lag on your next overseas holiday, and it all comes down to your modes of transport. </p> <p dir="ltr">Sleep researchers said it's good news for cruise lovers, as exposure to sea air and bright natural light improves sleep to cure the annoying condition quickly.</p> <p dir="ltr">Some experts say to avoid travelling by plane all together, and always opt for cruising holidays instead. </p> <p dir="ltr">However, if you have to travel to your cruise by plane, being on board is a great way to tackle the dreadful feeling, compared with holidaying on land, Panache Cruises said.</p> <p dir="ltr">Dr Lindsay Browning, expert at Trouble Sleeping said exposing yourself to bright lights at the right time after a long-haul flight is one of the most powerful things we can do to boost and help shift circadian rhythm, and being on a ship is the perfect place for that.</p> <p dir="ltr">"As a general rule, you want to get lots of bright light exposure during the daytime and avoid light at night," Browning said.</p> <p dir="ltr">"When travelling on a cruise ship, you will naturally get a lot of bright light exposure during the day, helping your circadian rhythm.”</p> <p dir="ltr">"Further, when travelling by ship you will have a cabin with a proper bed and curtain, enabling you to sleep at night when you want to."</p> <p dir="ltr">The company claimed research showed how prolonged exposure to sea air can improve blood oxygen levels, boost vitamin D, and improve breathing leading to higher-quality sleep, helping to rid travellers of pesky jet lag so they can enjoy their holidays. </p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

Why scalp care is just important as washing your hair

<p dir="ltr">When it comes to our daily beauty routines, we tend to focus on what looks and feels like it needs a refresh, such as washing our hair when it looks a little greasy, or cleansing our faces after a day of wearing makeup. </p> <p dir="ltr">While our beauty, skin and hair care routines are quick to become second nature, there is one area that often gets overlooked: our scalps. </p> <p dir="ltr">When washing our hair, it is easy to focus on the products and techniques we need to get our tresses clean, while skimping on what is best for our scalp. </p> <p dir="ltr">But now, the scalp, which is often the most overlooked part of our skin, is finally being recognised as an area that needs just as much TLC as your face.</p> <p dir="ltr">Implementing scalp care as part of our beauty routines is a must, as this sensitive area can often need extra attention due to a build-up of product, delicate skin and aggressive hair washing techniques. </p> <p dir="ltr">Hair care expert Sanja Scher from Beatnik Studio has shared how important it is to care for the scalp as the foundation for hair growth and health, and how it all starts with the right products. </p> <p dir="ltr">"Revlon Professional, known for game-changing professional haircare, styling, and colour, offers a range of products dedicated to improving the scalp - and they're available to take home.

How to fall asleep without sleeping pills: 7 natural sleep aids that actually work

<p>It’s 3am and you’re suddenly wide awake. Try these seven science-backed strategies to fall back to sleep fast.</p> <p><strong>Give meditation a try </strong></p> <p>As a mindfulness coach, I’m very aware of the day-to-day anxieties and worries that can interfere with a good night’s sleep. One of the most effective natural sleep aids is a quick meditation session to ease yourself out of those stresses. If you’ve never meditated before, you’ll likely find the meditation interrupted by thoughts flashing through your mind.</p> <p>It’s important for you to know that this isn’t a failure on your part, and that you aren’t doing anything wrong. Thinking is just what the brain does, as naturally as lungs take in air. The point is to be non-judgmental yet aware of your thoughts, bodily experiences and breath, moment by moment.</p> <p><em>Sleep better, feel better! <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/rollers-resistance/27-72435-gaiam-strengthen-stretch-kit?affiliate=GAIAM6O" target="_blank" rel="noopener">This Blackout Sleep Mask from Gaiam</a> will help you feel well rested and renewed. </em></p> <p><strong>Stop wanting to fall asleep</strong></p> <p>It’s counterintuitive, isn’t it? Sometimes trying too hard to do something is the very thing that prevents us from achieving it – and that’s never more true than when it comes to falling asleep. Desperately wanting to sleep will only stoke anxieties that will further stress your brain, essentially feeding it the message that it’s not safe to sleep.</p> <p>Throw in those worries about your to-do list at work the following day, and the whole thing can snowball into a panic attack. Try letting go of that feeling that you absolutely must sleep now, and observe your own anxieties for what they are without judgment. When you stop looking at sleep as a goal, you’ll find it easier to fall asleep.</p> <p><em>Before you climb into bed, set aside 10-15 minutes to help relax your body and mind, with <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/restore-massage/27-73353-gaiam-wellness-acupressure-neck-back-pillow?affiliate=GAIAM60" target="_blank" rel="noopener">this wellness acupressure neck and back pillow from Gaiam</a>.</em></p> <p><strong>Start a journal </strong></p> <p>If you find yourself struggling to fall asleep, pick up a pen and paper (not your phone!), and start writing: simply scribble down an account of what’s going on inside your head. Although there’s no “right” way to journal, you might start by listing the events of your day, and from there, how those events and encounters made you feel.</p> <p>Building this structured picture of your thoughts may help you see that the problem that’s keeping you up at night, and is likely less overwhelming than you thought. Why my insistence on a pen and paper? First off, studies show the simple motor action that’s involved in the act of handwriting has a calming effect. Secondly, the light emitted by laptops and phones isn’t conducive to falling asleep.</p> <p><strong>Find yourself a "3am friend"</strong></p> <p>Some of us are lucky to have a ‘3am friend’, that close confidant you can call up in the wee hours knowing that they won’t hold it against you in the morning. Although it’s great to have someone to talk to when you want to fall asleep, it’s important that the conversation doesn’t just rehash the anxieties that are preventing you from catching shut-eye in the first place.</p> <p>Rather than using the call to seek solutions for those issues, talk about things that calm your nerves, or even have them assist you in deep breathing. It may sound silly, but doing a series of deep, relaxing breaths can help you let go of the troubles that are keeping you wide awake.</p> <p><strong>Take a warm shower</strong></p> <p>Taking a warm shower not only relaxes your muscles and soothes minor aches and pains, but it also raises your core body temperature. As soon as you step out of the shower, your body starts working at lowering that temperature, which is something that normally happens when you’re falling asleep naturally.</p> <p>(That’s why we always feel the need for a blanket when we sleep, no matter how warm it is!) By kick-starting that temperature-lowering process, you’re tricking your body into falling asleep fast.</p> <p><strong>Stretch yourself to sleep </strong></p> <p>Anxiety keeping you up? Research suggests mild stretching can help take the edge off and relax muscles that have become stiff and sore after a long day. We’re not talking intricate yoga poses or acrobatics here, either: Simple stretches like an overhead arm stretch and bending over to touch your toes should do the trick. Ramp up the relaxation potential with a soundtrack of ambient noise at a volume that’s just barely audible.</p> <p>There are plenty of white noise apps that are free to download, but soft music can work as well (so long as there are no lyrics). Just remember, if you’re using an electronic device to play these sleep-promoting sounds, make sure it’s placed screen-down so you’re not distracted by the light it emits.</p> <p><em>Stretching is healing, and this <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/rollers-resistance/27-72435-gaiam-strengthen-stretch-kit?affiliate=GAIAM60" target="_blank" rel="noopener">Strengthen and Stretch Kit from Gaiam</a> is a great way to start. An on-line workout is also included to get you started.</em></p> <p><strong>Read (or listen!) to something new</strong></p> <p>When you’re struggling with insomnia, it might be tempting to pull an old favourite off the bookshelf. In reality, it’s better to read or listen to an audio book that covers a topic on which you know absolutely nothing. New information, while taking attention away from the stressors that are keeping you up at night, gives your brain enough of a workout to make it tire more quickly than when it’s engaged with familiar subjects and concepts.</p> <p>Again, if it’s an audio book or podcast you’re listening to, make sure the light-emitting side of the device is face down to keep the room as dark as possible. Darkness and warmth play an essential part in the production and maintenance of melatonin, the hormone that plays the central role falling asleep.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article by </em><em>Deepak Kashyap </em><em style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/conditions/sleep/how-to-fall-asleep-without-sleeping-pills-7-natural-sleep-aids-that-actually-work" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Your passport to salon-quality haircare on a budget

Is hyaluronic acid as effective as skincare brands claim?

<p><em><a href="https://theconversation.com/profiles/lian-liu-1459225">Lian Liu</a>, <a href="https://theconversation.com/institutions/university-of-surrey-1201">University of Surrey</a></em></p> <p>Hyaluronic acid has become a huge buzzword in the beauty industry, with everything from creams and cleansers to shampoos containing it. Often, these products are marketed to consumers with the promise that hyaluronic acid will boost hydration – important for keeping the skin looking its best.</p> <p><a href="https://www.frontiersin.org/articles/10.3389/fvets.2019.00192/full">Hyaluronic acid</a> is ubiquitous in our organs and tissues, playing a crucial role in the function of our cells and tissues.</p> <p>Hyaluronic acid has been in clinical use for decades, for example, as an injectable between joints to help <a href="https://pubmed.ncbi.nlm.nih.gov/31294035/">lubricate cartilage</a>. But at the turn of the century, cosmetic companies began using it as a moisturising ingredient in cosmetic products.</p> <p>Topically, it’s thought that hyaluronic acid works by holding and retaining water molecules in order to <a href="https://www.sciencedirect.com/science/article/abs/pii/S014181301833770X">hydrate the skin</a> and restore elasticity, preventing wrinkles. When combined with sunscreen, hyaluronic acid may be capable of protecting the skin against ultraviolet radiation as it has <a href="https://doi.org/10.1016/j.ijbiomac.2018.09.188">antioxidant properties</a> (meaning it prevents damage caused by oxidising agents, such as ultraviolet radiation).</p> <p>One of the most frequent marketing claims used to sell hyaluronic acid is the long-held belief that hyaluronic acid holds 1,000 times its weight in water. This means it can maintain moisture and reduce moisture loss.</p> <p>But this claim has been called into question recently, with <a href="https://www.newscientist.com/article/2418345-benefits-of-hyaluronic-acid-in-skincare-products-have-been-oversold/">numerous publications</a> recently discussing <a href="https://www.dailymail.co.uk/health/article-13140853/Benefits-hyaluronic-acid-skincare-oversold.html">the findings</a> of a <a href="https://chemrxiv.org/engage/chemrxiv/article-details/64b5b086b053dad33a6cdcaf">pre-print paper</a> which suggests this claim is not true.</p> <p>The authors of the pre-print, researchers from the University of California, looked into the molecule-binding properties of hyaluronic acid and water to test the claim that it can hold 1,000 times its weight in water.</p> <p>To do this, the researchers created a solution containing 1g of hyaluronic acid and 1,000g of water (0.1% of hyaluronic acid), which was compared with just water. They then applied heat to both solutions, measuring the thermal changes that occurred. They found that there was not much difference in the changes that occurred in the 0.1% hyaluronic acid solution compared with the pure water. They therefore concluded that the long-held claim is not true.</p> <p>These findings may have consumers wondering how well their hyaluronic acid products actually work if it doesn’t hydrate the skin as much as previously claimed.</p> <h2>How hyaluronic acid works</h2> <p>While there’s no disputing the experimental results obtained, the conclusion on hyaluronic acid’s water-holding capacity is not applicable to all forms of hyaluronic acids.</p> <p>Hyaluronic acid comes in different molecular sizes. This pre-print only looked at one medium-sized hyaluronic acid molecule in their experiments. This means the results may only be true for products containing medium and smaller sized hyaluronic acid molecules.</p> <p>When hylauronic acid interacts with water, its water-loving and water-hating parts lead to electrostatic repulsion. This enables large numbers of hyaluronic acid molecules to <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1468-3083.2004.01180.x">form networks</a>, which look a bit like honeycombs, and expand.</p> <p>The larger the hyaluronic acid’s molecule size, the more capable it is of forming these honeycomb structures – and also the more able it is to retain water relative to its own weight.</p> <p>Hyaluronic acid with larger molecular sizes will form these networks at a concentration of 0.1%, meaning it can hold 1,000 times its own weight in water. Some very large molecules will even form these networks at a <a href="https://pubmed.ncbi.nlm.nih.gov/2012600/">concentration as low as 0.05%</a>. This means it can hold 2,000 times its weight in water.</p> <p>It’s also worth noting that hyaluronic acid doesn’t just hold moisture and hydrate the skin. Because of its <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1468-3083.2004.01180.x">hydrating and antioxidant effects</a>, it also promotes cell regeneration and stimulates collagen production. So hyaluronic acid’s benefits go beyond its ability to retain water.</p> <p>Although this paper may have partially debunked one popular claim about hyaluronic acid’s moisturising abilities, that doesn’t mean you should stop using it. The research still shows there’s no doubt about hyaluronic acid’s moisturising abilities, which can leave skin softer, smoother and with fewer wrinkles. Plus, hyaluronic acid’s antioxidant effects promote the growth of new skin cells and collagen.</p> <p>But if you want to make sure you’re getting the most effective product possible, look for one containing multiple weights of hyaluronic acid molecules (sometimes labelled as “triple weight”, “multiweight” or “multi-molecular weight”).

Sunscreen: why wearing it even in winter could be a good idea

<p><em><a href="https://theconversation.com/profiles/karl-lawrence-404481">Karl Lawrence</a>, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p>Sunscreen has taken centre stage in many skincare routines, especially among those hoping to prevent visible signs of ageing. But while it makes sense to wear sunscreen every day in the summer when the sun’s rays are most powerful, many may wonder whether there’s any benefit of wearing sunscreen daily in the winter months.</p> <p>The sun’s radiation can reach us during all times of the year. This means that in both summer and winter, we are exposed to infrared radiation, as well as UVA and UVB rays.</p> <p>UVB is mainly responsible for sunburn and DNA damage – and can also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3709783/">cause skin cancers</a> as a result of long-term exposure. UVA radiation does contribute to these processes somewhat, but it’s less effective at doing so. UVA can penetrate deeper into the skin, however, which can damage the collagen – a key part of the skin that keeps it firm and elastic. This can cause the <a href="https://pubmed.ncbi.nlm.nih.gov/25234829/">skin to age faster</a>, leading to wrinkles, fine lines and changes in pigmentation.</p> <p>The amount of UVA and UVB radiation that reaches the Earth’s surface changes across the seasons. This is due to the angle of the Sun in the sky, as well as other factors such as latitude and time of day.</p> <p>For example, let’s compare how <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/php.12422">UVA and UVB radiation varies</a> at solar noon in London, UK and Kuala Lampur, Malaysia (which is near the equator).</p> <p>In latitudes closer to the equator (such as in Kuala Lampur), the amount of UVA and UVB radiation throughout the year remains fairly consistent. But in higher latitudes, such as London, there’s almost no UVB radiation throughout the winter months – whereas there’s still some UVA radiation.</p> <p>Not only that, but people living further from the equator may tend to spend less time exposed to the Sun in winter due to the colder temperatures and variable weather. And when they do go outside, they may cover their skin up – usually leaving only their face exposed to the Sun for much shorter periods of time.</p> <p>But UVA radiation can still penetrate through clouds and windows. While our exposure to these rays is probably minimal, skin damage from UV exposure is <a href="https://www.sciencedirect.com/science/article/pii/S0079610706000162">accumulated over decades</a>, so anything that can be done to reduce exposure (and damage) over time may be beneficial. This is also true of UVB exposure – although it is less relevant in winter months at higher latitudes.</p> <p>This may be where daily sunscreen use during the winter is still of benefit. Sunscreens are formulated to reduce exposure to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6978633/">both UVB and UVA rays</a> – although they are usually more effective at reducing exposure to UVB radiation. They have been designed in this way to prevent the most damaging effects of the Sun, such as sunburn and DNA damage. The impact of exposure to UVA radiation has only been considered more recently.</p> <p>Numerous studies have shown regular sunscreen use over many years is effective at <a href="https://onlinelibrary.wiley.com/doi/10.1111/phpp.12109">preventing skin damage</a>, photoaging and skin cancers. The most robust trials suggest daily sunscreen use is most effective, but this will be dependent on the factors discussed above.</p> <h2>The effects of altitude and snow</h2> <p>One place where winter sunscreen use is especially important is when skiing or snowboarding – or when you’re otherwise going to be outside for extended periods of time, at higher altitudes on snow-covered mountains.</p> <p>Both altitude and snow can increase the doses of <a href="https://www.who.int/news-room/questions-and-answers/item/radiation-ultraviolet-(uv)">UVA and UVB radiation</a> a person receives. Snow can reflect up to 80% of UV radiation emitted by the Sun – effectively almost doubling the doses received. Also, for every 1,000-foot increase in altitude, there’s a 10% increase in UV exposure. This is why it’s essential to protect the skin and eyes by wearing sunscreen, protective clothing and sunglasses that block both types of UV ray. This is also true when spending time in snowy environments, such as when hiking or skating.</p> <p>Sunscreens are generally regarded as safe and tend to have few adverse effects, so you don’t need to worry too much about wearing one throughout the year. However, there are some points to consider, especially if you have skin conditions. For example, sunscreen can <a href="https://www.byrdie.com/does-sunscreen-cause-acne-or-help-it-7546147">exacerbate acne</a> and cause <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7759112/">irritation and allergic reactions</a> – although these are rare.</p> <p>There are also emerging concerns from regulatory agencies about the <a href="https://jamanetwork.com/journals/jama/fullarticle/2759002">absorption of UV filters into the body</a>. However, the consequences of such absorption and the potential affects on health are not well defined and require more research.</p> <p>Still, the benefits of sunscreen have been widely demonstrated – as has their safety. So if you want to prevent premature signs of ageing, it’s important to use sunscreen at all times you may be exposed to the Sun – especially in the summer months. While the benefits of wearing sunscreen in winter are less well defined, there’s probably no harm in wearing one if you want to.</p> <p>If you decide to use sunscreen in winter, use ones that have broad spectrum five-star UVA protection. For day-to-day use, high SPF sunscreens are unlikely to provide a large benefit, particularly if spending only short periods outside. However, if skiing, a <a href="https://www.jaad.org/article/S0190-9622(17)31086-1/fulltext">high-SPF sunscreen</a> with five-star UVA protection would be beneficial.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/219640/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/karl-lawrence-404481"><em>Karl Lawrence</em></a><em>, Research fellow, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p><em>Image credits: </em><em>Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Fear of ageing is really a fear of the unknown – and modern society is making things worse

<p><em><a href="https://theconversation.com/profiles/chao-fang-1010933">Chao Fang</a>, <a href="https://theconversation.com/institutions/university-of-liverpool-1198">University of Liverpool</a> and <a href="https://theconversation.com/profiles/alastair-comery-1501915">Alastair Comery</a>, <a href="https://theconversation.com/institutions/university-of-bath-1325">University of Bath</a></em></p> <p>For the first time in human history, we have entered an era in which reaching old age is taken for granted. Unlike in ages past, when living to an older age was a luxury afforded mainly to the privileged, globally around <a href="https://data.worldbank.org/indicator/SP.DYN.TO65.FE.ZS?locations=1W">79% of women</a> and <a href="https://data.worldbank.org/indicator/SP.DYN.TO65.MA.ZS?locations=1W">70% of men</a> can expect to reach the age of 65 and beyond.</p> <p>Despite longer life expectancy, many people in the contemporary west see growing old as undesirable and <a href="https://www.theguardian.com/science/2023/apr/02/ageing-and-the-mortality-alarm-i-started-panicking-about-future-me">even scary</a>. Research shows, however, that anxiety about ageing may in fact be <a href="https://journals.sagepub.com/doi/abs/10.1177/0164027500225004">fear of the unknown</a>.</p> <p>Society’s <a href="https://www.psychologytoday.com/intl/articles/199409/learning-love-growing-old">focus on youthfulness</a> and <a href="https://www.apa.org/ed/precollege/psychology-teacher-network/introductory-psychology/ableism-negative-reactions-disability">capability</a> can cause anxiety about becoming weak and unwanted. Adverts for anti-ageing products <a href="https://theconversation.com/how-20th-century-rejuvenation-techniques-gave-rise-to-the-modern-anti-ageing-industry-133569">are everywhere</a>, reinforcing the idea that growing older is inherently unattractive.</p> <p>Some people fear ageing so much that it becomes a pathological condition <a href="https://mind.help/topic/gerascophobia/">called gerascophobia</a>, leading to irrational thoughts and behaviour, for example, a fixation on health, illness and mortality and a preoccupation with hiding the signs of ageing.</p> <p>We frequently hear about attempts to reverse ageing, often by the super rich. For example, <a href="https://fortune.com/well/2023/01/26/bryan-johnson-extreme-anti-aging/">Bryan Johnson</a>, a 45-year-old American entrepreneur, is spending millions of dollars a year to obtain the physical age of 18.</p> <p>While the desire to reverse ageing is not a new phenomenon, advancements in biomedicine have brought it closer.</p> <p>Work published by genetics professor <a href="https://lifespanbook.com/">David Sinclair</a> at Harvard University in 2019 suggests that it may be possible to challenge the limits of cell reproduction to extend our lifespan, for example. His <a href="https://www.nature.com/articles/s43587-023-00527-6">information theory of ageing</a> argues that <a href="https://epigeneticsandchromatin.biomedcentral.com/articles/10.1186/1756-8935-6-3">reprogramming DNA</a> can improve damaged and old tissues, and delay or even reverse ageing. However, these new possibilities can also heighten our fear of ageing.</p> <h2>From the unproductive to undervalued</h2> <p>People haven’t always dreaded growing older. In many societies, older people used to be widely regarded as wise and important – and in some they still are.</p> <p>In ancient China, there was a <a href="https://www.jstor.org/stable/605890">culture</a> of respecting and seeking advice from older family members. There is still an ethos of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6363941/">filial piety</a> (showing reverence and care for elders and ancestors) today, even if it’s not as pronounced as it used to be. The same went for <a href="https://www.cambridge.org/core/journals/ageing-and-society/article/abs/old-age-in-the-dark-ages-the-status-of-old-age-during-the-early-middle-ages/3699DC4100DE852BDA1E1B3BBF33DDBC">medieval Europe</a>, where older people’s experiences and wisdom were highly valued.</p> <p>However, the industrial revolution in the west from the 18th century led to a cultural shift where older people <a href="https://link.springer.com/article/10.1023/A:1014358415896">became excluded from society</a> and were considered unproductive. People who had surpassed the age to work, alongside those with incurable diseases, were regarded by society as <a href="https://www.tandfonline.com/doi/abs/10.1080/13607860903228762">“evils”</a> in need of assistance.</p> <p>The treatment of older people has taken a different form since the early 20th century. The introduction of <a href="https://www.nytimes.com/2018/12/30/business/retirement/why-the-world-needs-to-rethink-retirement.html">universal pension systems</a> made ageing a central concern in welfare systems. But as the demands for social and health care have increased, journalists increasingly portray ageing as a <a href="https://www.ageuk.org.uk/latest-news/archive/older-people-feel-a-burden-to-society/">burden</a> on society.</p> <p>Consequently, growing older is often associated with managing the risk of ill health and alleviating the onus of care from younger relatives. This can result in the <a href="https://utpjournals.press/doi/abs/10.3138/utq.90.2.09">institutionalisation</a> of older people in residential facilities that keep them hidden, sequestered from the awareness of younger generations.</p> <p><a href="https://journals.sagepub.com/doi/abs/10.1177/0164027500225004">Research</a> analysing the responses of 1,200 US adults from the American Association of Retired Persons’ Images of Ageing survey shows that much of the perceived fear of ageing is closely aligned with the fear of the unknown, rather than the ageing process itself. This fear is only exacerbated by the largely separate lives lived by older and younger generations.</p> <p>The prevalence of nuclear families and the decline of <a href="https://www.cpc.ac.uk/docs/BP45_UnAffordable_housing_and_the_residential_separation_of_age_groups.pdf">traditional mixed-generational communities</a> have deprived younger people of the opportunity to more fully understand the experiences of older people. Plus, the rapid increase in <a href="https://news.sky.com/story/why-its-more-difficult-for-young-people-to-buy-a-house-now-than-it-was-fifty-years-ago-12537254">house prices</a> means many young people cannot afford to live near their older relatives.</p> <p>The separation of older people from children and young people has sparked generational conflicts that seemingly continue to <a href="https://www.economist.com/britain/2017/05/04/britains-generational-divide-has-never-been-wider">grow wider than ever</a>.

It’s one of the most commonly reported <a href="https://pubmed.ncbi.nlm.nih.gov/32249998/">bothersome urinary symptoms</a> (others include urgency and poor stream).</p> <p>So what causes nocturia, and how can it affect wellbeing?</p> <h2>A range of causes</h2> <p>Nocturia can be caused by a variety of <a href="https://www.health.gov.au/sites/default/files/nocturia-going-to-the-toilet-at-night_0.pdf">medical conditions</a>, such as heart or kidney problems, poorly controlled diabetes, bladder infections, an <a href="https://www.nature.com/articles/s41598-023-44916-8">overactive bladder</a>, or gastrointestinal issues. Other causes include pregnancy, <a href="https://onlinelibrary.wiley.com/doi/10.1002/nau.24839">medications</a> and consumption of alcohol or caffeine before bed.</p> <p>While nocturia causes disrupted sleep, the reverse is true as well. Having broken sleep, or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4055528/">insomnia</a>, can also cause nocturia.</p> <p>When we sleep, an antidiuretic hormone is released that slows down the rate at which our <a href="https://theconversation.com/is-urine-sterile-do-urine-therapies-work-experts-debunk-common-pee-myths-191862">kidneys produce urine</a>. If we lie awake at night, less of this hormone <a href="https://journals.physiology.org/doi/full/10.1152/ajprenal.00025.2023">is released</a>, meaning we continue to produce normal rates of urine.

Elle Macpherson's stunning runway return

<p>It's been 14 years since Elle Macpherson last walked the runway and the Aussie supermodel is finally back! </p> <p>On Monday, the 59-year-old walked the run for the first time in forever and she did not miss a step. </p> <p>The supermodel strutted down the PayPal Runway to kickstart the 2024 Melbourne Fashion Festival at the Royal Exhibition Building.</p> <p>She looked chic in her first look which was a plunging layered plissé black dress and an oversized blazer by beloved Aussie brand Aje. </p> <p>She then rocked a pop of colour in a canary yellow oversized coat and matching trousers from Bianca Spender. In her final look she donned a fluffy sweater and scarf from Viktoria & Woods completed with a brown coat with a dramatic train.</p> <p>Ahead of her runway return, Macpherson said: “I’m honoured to support PayPal in promoting Australian fashion globally.</p> <p>"PayPal’s platform gives creative talents and small businesses the opportunity to grow internationally by building customer trust," she added. </p> <p>“From personal experience, I know the challenges of taking a business global, and how valuable trusted partners are in that process.”</p> <p>In an interview with the <em>Herald Sun</em>, she told the publication that she was grateful for her Australian heritage and for Australian brands being given an opportunity to shine. </p> <p>PayPal supports over 150,000 Australian fashion businesses and has a total of 380 million shoppers worldwide.</p> <p>Shane Capron, the senior director of consumer engagement at PayPal praised Macpherson's work. </p> <p>“Elle was fabulous – so excited that we were able to bring her back to the catwalk for the PayPal Runway on the eve of her 60th birthday. What an Australian icon. Such an inspiration,” Capron said. </p> <p>“This year the PayPal runway is all about celebrating the success of Australian fashion brands that have achieved success on the global stage – just like Elle.</p> <p>"Not only is Elle an Australian who became a world-famous supermodel, she is also an incredible businesswoman who has launched globally successful brands.”</p> <p>Her partnership with PayPal will also support UNICEF in a multinational fundraising campaign later this year.</p> <p><em>Images: Getty</em></p>

Why and how often do I need to wash makeup brushes and sponges?

<p><em><a href="https://theconversation.com/profiles/enzo-palombo-249510">Enzo Palombo</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rosalie-hocking-1428271">Rosalie Hocking</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>From the bristles of brushes to the porous surfaces of sponges, your makeup kit can harbour a host of bacteria and fungi.</p> <p>These potentially hazardous contaminants can originate not only from the cosmetics themselves, but also from the very surface of our skin.</p> <p>So, how can we keep things hygienic and avoid microbial growth on makeup brushes and sponges? Here’s what you need to know.</p> <h2>How do germs and fungi get in my brushes and sponges?</h2> <p>Germs and fungi can make their way into your makeup kit in lots of ways.</p> <p>Ever flushed a toilet with the lid open with your makeup brushes nearby? There’s a good chance <a href="https://theconversation.com/mobile-phones-are-covered-in-germs-disinfecting-them-daily-could-help-stop-diseases-spreading-135318">faecal particles</a> have landed on them.</p> <p>Perhaps a family member or housemate has used your eyeshadow brush when you weren’t looking, and transferred some microbes across in the process.</p> <p>Bacteria that trigger a pimple outbreak can be easily transferred from the surface of your skin to a makeup brush or sponge.</p> <p>And tiny little mites called Demodex mites, which have been linked to certain rashes and acne, live on your skin, as well, and so may end up in your sponge or brushes.</p> <p>Bacterial contamination of <a href="https://pubmed.ncbi.nlm.nih.gov/38020232/">lip cosmetics</a>, in particular, can pose a risk of skin and eye infections (so keep that in mind if you use lip brushes). Lipsticks are frequently contaminated with bacteria such as <em>Staphylococcus aureus</em>, <em>E. coli</em>, and <em>Streptococcus pneumoniae</em>.</p> <p>Low-quality cosmetics are more likely to have higher and more diverse microbial growth compared to <a href="https://www.sciencedirect.com/science/article/pii/S1319562X23002978?pes=vor">high-quality cosmetics</a>.</p> <p>Brushes exposed to sensitive areas like the eyes, mouth and nose are particularly susceptible to being potential sources of infection.</p> <p>The range of conditions caused by these microorganisms includes:</p> <ul> <li> <p>abscesses</p> </li> <li> <p>skin and soft tissue infections</p> </li> <li> <p>skin lesions</p> </li> <li> <p>rashes</p> </li> <li> <p>and dermatitis.</p> </li> </ul> <p>In severe cases, infections can lead to invasion of the bloodstream or deep tissues.</p> <p>Commercially available cosmetics contain varying amounts and types of preservatives aimed at inhibiting the growth of fungi and bacteria.</p> <p>But when you apply makeup, different cosmetics with unique formulations of preservatives can become mixed. When a preservative meant for one product mixes with others, it might not work as well because they have different water amounts or pH levels.</p> <p>So preservatives are not foolproof. We also need to observe good hygiene practices when it comes to brushes and other cosmetics applicators.</p> <h2>Keeping brushes clean</h2> <p>Start with the basics: never <a href="https://www.semanticscholar.org/paper/Isolation-of-Pathogenic-Microbes-from-Beauty-Salons-Hassan-Hamad/0199635290628fe326fcd04a2b8a2422884a8240">share makeup brushes or sponges</a>. Everyone carries different microbes on their skin, so sharing brushes and sponges means you are also sharing germs and fungi.</p> <p>If you need to share makeup, use something disposable to apply it, or make sure any shared brushes are washed and sterilised before the next person uses it.</p> <p>Clean makeup brushes by washing with hot soapy water and rinsing thoroughly.</p> <p>How often? Stick to a cleaning routine you can repeat with consistency (as opposed to a deep clean that is done annually). <a href="https://www.aad.org/public/everyday-care/skin-care-secrets/routine/clean-your-makeup-brushes#:%7E:text=To%20protect%20your%20skin%20and,every%207%20to%2010%20days.">Once a week</a> might be a good goal for some, while others may need to wash more regularly if they are heavy users of makeup.</p> <p>Definitely wash straight away if someone else has used your brushes or sponges. And if you’ve had an eye infection such as conjunctivitis, ensure you clean applicators thoroughly after the infection has resolved.</p> <p>You can use bactericidal soap, 70% ethanol or chlorhexidine solutions to wash. Just make sure you wash very thoroughly with hot water after, as some of these things can irritate your skin. (While some people online say alcohol can degrade brushes and sponges, opinion seems to be mixed; in general, most disinfectants are unlikely to cause significant corrosion.)</p> <p>For some brushes, heating or steaming them and letting them dry may also be an effective sterilisation method once they are washed with detergent. Microwaving sponges isn’t a good idea because while the heat generated by a domestic microwave would kill microbes, it would need temperatures approaching 100°C for a decent period of time (at least several minutes). The heat could melt some parts of the sponge and hot materials could be a scalding hazard.</p> <p>Once clean, ensure brushes and sponges are stored in a dry place away from water sources (and not near an open toilet).</p> <p>If you’re having makeup applied professionally, brushes and applicators should be sterilised or changed from person to person.</p> <h2>Should I wash them with micellar water?</h2> <p>No.</p> <p>Not only is this expensive, it’s unnecessary. The same benefits can be achieved with cheaper detergents or alcohol (just rinse brushes carefully afterwards).</p> <p>Disinfection methods such as using bactericidal soap, 70% ethanol, or chlorhexidine are all very good at reducing the amount of microbes on your brushes and sponges.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/220280/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/enzo-palombo-249510"><em>Enzo Palombo</em></a><em>, Professor of Microbiology, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rosalie-hocking-1428271">Rosalie Hocking</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Drinking olive oil: a health and beauty elixir or celebrity fad in a shot glass?

<p><em><a href="https://theconversation.com/profiles/hazel-flight-536221">Hazel Flight</a>, <a href="https://theconversation.com/institutions/edge-hill-university-1356">Edge Hill University</a></em></p> <p>In the ever-changing world of wellness trends and celebrity endorsed health fads there is a new trend on the scene: daily olive oil shots.</p> <p>Celebrities such as <a href="https://poosh.com/why-kourtney-kardashian-drinks-tablespoon-evoo/">Kourtney Kardashian</a>, Beyonce, Gwyneth Paltrow and <a href="https://www.womanandhome.com/life/news-entertainment/jennifer-lopez-credits-her-grandmas-crazy-beauty-secret-for-glowing-skin-and-chances-are-you-already-have-it-at-home/">Jennifer Lopez</a> all extol the virtues of swigging extra virgin as well as slathering it on their skin, crediting olive oil for their glowing complexions.</p> <p>Lopez even based her JLo Beauty brand around the kitchen staple, claiming that her age-defying looks were not the result of botox or surgery but the family beauty secret: <a href="https://graziamagazine.com/us/articles/jennifer-lopez-skincare-routine/">moisturising with olive oil</a>.</p> <p>And she’s in good company. Hollywood star <a href="https://jnews.uk/goldie-hawn-swears-by-olive-oil-for-perfect-skin-at-76-best-life/">Goldie Hawn reportedly drinks olive oil</a> before bed and uses it topically as a moisturiser, while <a href="https://www.redonline.co.uk/beauty/a31184313/julia-roberts-olive-oil-hair-skin/">beauty icon Sophia Loren</a> really goes to town by bathing in the stuff.</p> <p>While these celebrities swear by the skin beautifying properties of olive oil, some skin types should <a href="https://scholarhub.ui.ac.id/cgi/viewcontent.cgi?article=1182&context=jdvi#:%7E:text=Background%3A%20Dry%20skin%20or%20xerosis,water%20in%20the%20stratum%20corneum.">give it a swerve</a>.

Viral videos show influencers tossing back shots of cult olive oil brands, and proclaiming a wide range of health benefits from improving digestion to clearing up acne.</p> <p>Celebrity and influencers are sold on liquid gold but what about the rest of us? Can drinking olive oil really work on miracles for our health?</p> <h2>The benefits of olive oil</h2> <p>There’s no doubt that olive oil is full of good stuff. It’s high in polyphenols and antioxidants, which have protective qualities for the body’s tissues. It’s also a rich source of essential fatty acids, including oleic acid, which is known for <a href="https://foodrevolution.org/blog/olives-and-olive-oil-benefits/#:%7E:text=Compared%20with%20olives%2C%20olive%20oil,in%20polyphenols%20and%20antioxidants%2C%20however">lowering cholesterol</a> so reducing the chances of heart disease.</p> <p>Research has found that the inclusion of olive oil in the diet shows encouraging effects in a variety of <a href="https://doi.org/10.3390%2Fnu11092039">inflammatory and medical diseases</a> and can <a href="https://doi.org/10.3389%2Ffnut.2022.980429">support weight management</a> if used correctly.</p> <p>Replacing butter, margarine, mayonnaise and dairy fat with olive oil has been linked to a <a href="https://doi.org/10.1016%2Fj.jacc.2021.10.041">lower risk of mortality</a>. There’s also evidence to suggest that the protective compounds in olive oil may help <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0261649">guard against cancer</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10376491/">dementia</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/29141573/">support the liver</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7916323/">and kidneys</a>.</p> <p>But none of this is new information to health professionals. The health benefits of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7466243/">extra virgin olive oil</a> are <a href="https://doi.org/10.3390%2Fnu11092039">well researched</a> and nutritionists have promoted olive oil as a swap for saturated cooking fat for years.</p> <p>After all, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7536728/">Mediterranean diet</a> has been touted as one of the healthiest diets in the world for decades. The diet itself can vary from region to region, but <a href="https://doi.org/10.3390%2Fnu15092127">virgin olive oil</a> is a <a href="https://doi.org/10.3390%2Fnu11092039">consistent element</a>. It’s used as the <a href="https://www.themediterraneandish.com/cooking-with-olive-oil/">main source of cooking fat</a> and included in everything from salad dressings to bread.</p> <figure><iframe src="https://www.youtube.com/embed/krFcE5IPT7g?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Can fat be healthy? Yes and no</h2> <p>Fats are crucial for a balanced diet, aiding in the absorption of fat-soluble vitamins A,D,E,K and enhancing the nutritional value of meals.</p> <p>However, fat of any kind is also dense in calories and excessive consumption <a href="https://doi.org/10.1159/000336848">can lead to weight gain</a>. According to the <a href="https://www.who.int/news/item/17-07-2023-who-updates-guidelines-on-fats-and-carbohydrates">World Health Organization</a>, to prevent unhealthy weight gain, adults should limit their intake of fat to 30% of total energy intake with no more than 10% coming from saturated fats.</p> <p>Two tablespoons of olive oil – the standard amount in the shots taken by celebrities and social media influencers – contain 28g of fat (238 calories) and 3.8g of saturated fat equating to <a href="https://fdc.nal.usda.gov/fdc-app.html#/food-details/171413/nutrients">19% of the recommended daily intake</a>.</p> <p>That daily shot of extra virgin, then, might not be the best idea. Adding small amounts of olive oil to meals throughout the day is a more balanced – and appetising – approach to incorporating healthy fats into your diet.</p> <p>But what about Kourtney Kardashian’s <a href="https://poosh.com/why-kourtney-kardashian-drinks-tablespoon-evoo/#:%7E:text=First%20things%20first%2C%20it's%20recommended,a.m.%20(every%20other%20day).">claim that</a>: “It’s recommended to consume extra virgin olive oil in the morning on an empty stomach so the oil can coat your system and neutralize your stomach walls for optimal benefits?”</p> <p><a href="https://www.oliveoiltimes.com/briefs/consuming-olive-oil-on-an-empty-stomach-health-benefits/91503">Some brands</a> have also echoed the idea that consuming olive oil on an empty stomach offers unique health benefits. But no. There’s no scientific evidence to suggest this is true.</p> <p>For a healthy but more satisfying snack, Kourtney might try including a handful of olives into her daily diet. Olives offer the same rich array of nutrients, including vitamins E, A and K, alongside essential minerals such as iron, calcium, magnesium, potassium and amino acids.</p> <p>Unlike olive oil, olives have the added benefit of a high fibre content. The combination of fat and fibre enhances feelings of satiety, making olives a nutritious addition to the diet.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224018/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/hazel-flight-536221">Hazel Flight</a>, Programme Lead Nutrition and Health, <a href="https://theconversation.com/institutions/edge-hill-university-1356">Edge Hill University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

11 beauty trends that should have never happened

<p><strong>Avoid these beauty buzzkills at all costs</strong></p> <p>Recent years have seen particularly vibrant, eccentric and unpredictable movements in the beauty sphere. Don’t get us wrong; beauty is an aesthetic concept that is indeed subjective to the eye of the beholder, but some of these recent trends aren’t as appealing as you might think.</p> <p>While you’re recovering from the traumatic fashion trends embedded in our history, take comfort in knowing that just about every decade has encountered questionable decisions – whether that be sartorial or cosmetic. If the thought of sporting orange Crocs and popcorn shirts makes you cringe, consider discarding these unflattering beauty trends as well.</p> <p>As proven peeves for guys, makeup artists and job employers alike, these 11 beauty trends actually do the opposite of their intended purpose.</p> <p><strong>Overly sticky lip gloss</strong></p> <p>We all love to sport a glossy pout, but when your lips are so sticky that they begin to look like you doused your mouth in maple syrup, that’s a problem. Wearing it outside especially doesn’t help; nobody likes spending the day with sticky, raspberry pink-streaked strands. Not surprisingly, men aren’t fans of it either; surveys have found that the majority of men vote against women donning it on a dinner date.</p> <p>Not only does it diminish the whole effortless, woke-up-like-this impression you’re trying to pull off, but nobody wants to make out with super glue. Instead, try opting for long-lasting lip tints that moisturise with a subtle sheen.</p> <p><strong>Extensive self-tanner</strong></p> <p>Unless you’re naturally blessed with the wondrous genes of a luminous rose gold complexion, the rest of us mere mortals have been turning to self-tanners to bestow that subtle bronze glow.</p> <p>This doesn’t come with no strings attached however; not only can it ruin that expensive white cashmere sweater you just bought, one coat too many and you’ll begin to resemble a baked pastry. Instead of that “fresh-out-of-the-oven” look, try a tinted moisturiser instead.</p> <p><strong>Stiff hair </strong></p> <p>Applying too much hairspray can make your locks crunchier than a forest floor during September. Instead of spritzing half a bottle of hairspray on your poor scalp, keep it minimal or natural.</p> <p><strong>Hair add-ins </strong></p> <p>While synthetic clip-ons can be cute on a kid or at Coachella, feathers, extensions, and bells on a regular basis can come off rather childish.</p> <p>To prevent looking like a walking Christmas tree (and avoid making your hair look like an arts-and-crafts project), opt for dangling these trinkets on handbags or sporting them as jewellery instead.</p> <p><strong>Neon lips </strong></p> <p>While we’ve all seen the numerous images floating of (admittedly cool-looking) vibrant lipstick styles all over Pinterest, we’re still left scratching our heads as to what public setting one can don a neon green pout.</p> <p>Sporting electrifying colours too drastically divergent from your natural lip colour may make yourself come off as unprofessional and overly aggressive, so it’s best to stay away from the popping lips if you’re attending a job interview.</p> <p><strong>Wet hair look</strong></p> <p>Makeup artists worldwide have predicted this to be the major hair trend of the year. With celebrities like Rosie Huntington-Whiteley and Kim Kardashian West donning it on red carpets and said to have been inspired from Calvin Klein’s campaigns in the ‘90s, it has caught major spotlight everywhere.</p> <p>Although the tousled, wet hair look may look nice on the beachside, having a twist with too much slick on the streets may just come across as greasy, unwashed hair.</p> <p><strong>Colour-blocked makeup </strong></p> <p>Colour-blocking on clothing is undeniably chic, but colour-blocked makeup can make your face appear much too angular, and not in a good way. If you want to avoid looking like a makeup novice, don’t neglect the blending brush.</p> <p><strong>Hangover makeup</strong></p> <p>You know those mornings after a particularly rough night out, and you awaken to the sight of a bloated, saggy face? Well, now there’s a makeup trend striving for just that. A new trend known as “hangover beauty,” this look praises “aegyo-sal” (translated into “charming fat”), striving to highlight the puffiness under one’s eyes.</p> <p>To achieve the look, one has to line the bags underneath the eye and add blush above the cheekbones before blending them together into a reddish hue. This one’s pretty straightforward: don’t try to enhance what the rest of society usually tries to cover up.</p> <p>While having your eyes appear puffy and red-rimmed may have been an intentional choice for you, chances are people are just going to wonder how much sleep you got last night.</p> <p><strong>Furry nails</strong></p> <p>Ever since Jan Arnold, renown co-founder of CND nail polish, showcased furry nails on the runway, people have been plastering actual faux fur on their nails. Several obvious questions arise to the impracticality factor of this trend (how do you even eat or wash your hands with those?), but this nail art might be stretching it a tad too far, even for nail aficionados.</p> <p>You don’t want someone holding your hand to feel like he’s on a date with Sasquatch, so stick with the gel and acrylic for first impressions.</p> <p><strong>Stark ombre hair </strong></p> <p>Don’t get us wrong; we love ombre for many reasons – when done right. The biggest advice you could take for this is to seriously invest in a reputable hair stylist, or else your hair may just end up looking like you are in desperate need of a root touch-up.</p> <p>Never go cheap with ombre, and make sure your colour transition is gradual as opposed to stark.</p> <p><strong>Bleached brows</strong></p> <p>We have Cara Delevingne to thank for sparking the brow obsession; the pencil-thin arches reminiscent of the ’90s have officially been eliminated for thicker, fuller brows. But if you thought microblading was a bold move, think again.</p> <p>Stars like Katy Perry, Kendall Jenner and Rita Ora have all plunged into the peroxide party, inciting an entire movement of people grabbing the bleach to make their arches completely invisible. While that’s fine and all – if you’re into that sort of thing – fuller brows are proven to make you look younger.</p> <p><em>Image credits: Getty Images </em></p> <p><em>This article was originally published on <a href="https://www.readersdigest.com.au/healthsmart/beauty/11-beauty-trends-that-should-have-never-happened?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Why Barnaby Joyce’s TV diagnosis of insomnia plus sleep apnoea is such a big deal

<p><em><a href="https://theconversation.com/profiles/alexander-sweetman-1331085">Alexander Sweetman</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p>The <a href="https://theconversation.com/view-from-the-hill-how-does-david-littleproud-handle-the-latest-barnaby-joyce-embarrassment-223289">health</a> of Nationals MP Barnaby Joyce is in the news again, this time with a diagnosis of a sleep disorder made <a href="https://www.afr.com/companies/media-and-marketing/barnaby-joyce-to-be-diagnosed-with-a-sleep-disorder-on-live-tv-20240223-p5f79q">while filming</a> a TV documentary.</p> <p>Joyce’s diagnosis of insomnia plus sleep apnoea arose while filming <a href="https://www.sbs.com.au/whats-on/article/australias-sleep-revolution-with-dr-michael-mosley/nuyko305b">Australia’s Sleep Revolution with Dr Michael Mosley</a> in 2023. SBS has confirmed episode three, in which my Flinders University colleagues reveal his sleep disorder, is set to air on March 20.</p> <p>I was not involved in the program and have no knowledge of Joyce’s <a href="https://www.theaustralian.com.au/weekend-australian-magazine/australias-sleep-crisis-has-flinders-university-cracked-the-code-to-a-better-nights-sleep/news-story/d3b82617af33fff82487da2534722733">ongoing health care</a>. But I was part of the research team that in 2017 <a href="https://doi.org/10.1016/j.smrv.2016.04.004">coined the term COMISA</a> (co-morbid insomnia and sleep apnoea), the official name of Joyce’s on-screen diagnosis. Since then, I’ve led research into this <a href="https://doi.org/10.1016/j.smrv.2019.01.004">common</a> sleep disorder.</p> <p>Here’s why it’s so important to diagnose and treat it.</p> <h2>What was Joyce’s diagnosis?</h2> <p>People can be diagnosed separately with <a href="https://www.sleephealthfoundation.org.au/sleep-disorders/insomnia-2">insomnia</a> or <a href="https://www.sleephealthfoundation.org.au/sleep-disorders/obstructive-sleep-apnoea">sleep apnoea</a>.</p> <p>Insomnia includes frequent difficulties falling asleep at the start of the night or difficulties staying asleep during the night. These can result in daytime fatigue, reduced energy, concentration difficulties and poor mood. Over time, insomnia can start to impact your <a href="https://theconversation.com/insomnia-and-mental-disorders-are-linked-but-exactly-how-is-still-a-mystery-212106">mental health</a> and quality of life.</p> <p>Sleep apnoea (specifically, obstructive sleep apnoea) is when people experience repeated interruptions or pauses in breathing while they sleep. This reduces oxygen levels during sleep, and you can wake up multiple times at night. People with sleep apnoea may be aware of loud snoring, gasping for air when they wake up, or feeling exhausted the next morning. However, not all people have these symptoms, and sleep apnoea can go undiagnosed for years.</p> <p>But in Joyce’s case, both insomnia and sleep apnoea occur at the same time.</p> <p>We’ve known this could happen since <a href="https://doi.org/10.1126/science.181.4102.856">the 1970s</a>, with <a href="https://psycnet.apa.org/doi/10.1037/0022-006X.67.3.405">evidence growing</a> over <a href="https://doi.org/10.1378/chest.120.6.1923">subsequent decades</a>. Since then, sleep researchers and clinicians around the world have learned more about how <a href="https://doi.org/10.1016/j.smrv.2019.01.004">common</a> this is, its <a href="https://doi.org/10.1183/13993003.01958-2021">consequences</a> and how best to <a href="https://doi.org/10.1111/jsr.13847">treat it</a>.</p> <h2>How do you know if you have it?</h2> <p>Many people <a href="https://doi.org/10.1016/j.sleep.2005.08.008">seek help</a> for their sleep problems because of fatigue, exhaustion, physical symptoms, or poor mood during the day.</p> <p>If you think you have insomnia, a GP or sleep specialist can talk to you about your sleep pattern, and might ask you to complete <a href="https://www.sleepprimarycareresources.org.au/insomnia/assessment-questionnaires">brief questionnaires</a> about your sleep and daytime symptoms. You might also be asked to fill in a “sleep diary” for one to two weeks. These will allow a trained clinician to see if you have insomnia.</p> <p>If you or your GP think you may have (or are at risk of having) sleep apnoea, you may be referred for a sleep study. This normally involves sleeping overnight in a sleep clinic where your sleep patterns and breathing are monitored. Alternatively, you might be set up with a recording device to monitor your sleep at home. A trained medical professional, such as a sleep and respiratory physician, will often make the diagnosis.</p> <p><a href="https://doi.org/10.1016/j.smrv.2021.101519">Up to 50%</a> of people with sleep apnoea report symptoms of insomnia. About <a href="https://doi.org/10.1016/j.smrv.2021.101519">30–40%</a> of people with insomnia also have sleep apnoea.</p> <h2>What are the consequences?</h2> <p>Insomnia and sleep apnoea (individually) are associated with reduced <a href="https://theconversation.com/a-short-history-of-insomnia-and-how-we-became-obsessed-with-sleep-211729">sleep quality</a>, <a href="https://theconversation.com/insomnia-and-mental-disorders-are-linked-but-exactly-how-is-still-a-mystery-212106">mental health</a> and <a href="https://theconversation.com/health-check-heres-what-you-need-to-know-about-sleep-apnoea-26402">physical health</a>.</p> <p>Importantly, people with both at the same also tend to <a href="https://doi.org/10.3390/brainsci9120371">experience</a> worse sleep, daytime function, mental health, physical health and quality of life, compared with people with no sleep disorder.</p> <p>For instance, we know having both conditions comes with an <a href="https://doi.org/10.1111/jsr.13563">increased risk</a> of diseases of the heart.</p> <p><a href="https://doi.org/10.2147/NSS.S379252">In</a> <a href="https://doi.org/10.1183/13993003.01958-2021">three</a> <a href="https://doi.org/10.1016/j.sleepe.2022.100043">studies</a>, we found people with both insomnia and sleep apnoea have about a 50–70% higher risk of dying early from any cause, compared with people with neither sleep condition. People with insomnia alone and sleep apnoea alone did not have an increased risk of dying early.</p> <p>However, there are effective treatments to reduce these health consequences.</p> <h2>How is it treated?</h2> <p>In general, it is best for people to access evidence-based treatments for both disorders. These treatments vary according to the patient and the severity of their condition.</p> <p>For instance, wearing a <a href="https://www.sleephealthfoundation.org.au/sleep-disorders/cpap-continuous-positive-airway-pressure">CPAP mask</a> while sleeping improves breathing during sleep and reduces many of the daytime consequences of obstructive sleep apnoea. However, other effective treatments may be recommended based on each person’s symptoms, such as weight management, avoiding sleeping on your back, <a href="https://www.sleephealthfoundation.org.au/sleep-disorders/oral-appliances-to-treat-snoring-and-obstructive-sleep-apnoea-osa">oral devices</a> (which look a bit like a mouthguard), or surgery.</p> <p>The <a href="https://theconversation.com/how-can-i-get-some-sleep-which-treatments-actually-work-212964">most effective</a> treatment for insomnia is cognitive behavioural therapy for insomnia, also known as <a href="https://www.sleepprimarycareresources.org.au/insomnia/cbti">CBTi</a>. About four to eight sessions often lead to improvements in sleep, daytime function and mental health that are maintained for many <a href="https://doi.org/10.1080/16506073.2021.2009019">years</a>. This can be delivered by trained therapists such as psychologists, nurses or GPs, as well as via <a href="https://www.sleepprimarycareresources.org.au/insomnia/cbti/referral-to-digital-cbti-programs">online</a> programs.</p> <p>Last year, we drew together evidence from more than 1,000 people with both conditions. We found CBTi is an <a href="https://doi.org/10.1111/jsr.13847">effective treatment</a> for insomnia in people with treated and untreated sleep apnoea.</p> <h2>New treatments and approaches</h2> <p><a href="https://www.frontiersin.org/articles/10.3389/frsle.2024.1355468/abstract">We</a> and <a href="https://doi.org/10.1186/s13063-022-06753-4">other teams</a> internationally are developing and testing new ways of delivering CBTi.</p> <p>Several groups are testing devices, which <a href="https://doi.org/10.1002%2Flio2.761">stimulate</a> the tongue muscles during sleep, to treat sleep apnoea in people with both disorders.</p> <p>And we’re still working out the best order for patients to access treatments, and the best combination of treatments.</p> <h2>The power of TV</h2> <p>Joyce’s public diagnosis of both insomnia and sleep apnoea will no doubt raise awareness of what we suspect is an underdiagnosed condition.</p> <p>Based on how common insomnia and sleep apnoea are in Australia, we estimate Joyce is one of about <a href="https://doi.org/10.1016/j.sleep.2021.03.023">5–10%</a> of Australian adults to have both at the same time.</p> <p>The Conversation contacted Joyce’s spokesperson for comment but did not hear back before deadline.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224616/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/alexander-sweetman-1331085">Alexander Sweetman</a>, Research Fellow, College of Medicine and Public Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is micellar water and how does it work?

<p><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Micellar water, a product found in supermarkets, chemists and bathroom cabinets around the world, is commonly used to remove make-up. It’s a very effective cleanser and many people swear by it as part of their skincare routine.</p> <p>So, what is micellar water and why is it so good at getting makeup and sunscreen off? Here’s the science.</p> <h2>What are micelles?</h2> <p>Oil and water generally don’t mix, which is why you’ll struggle to remove makeup and sunscreen (which both contain oils) with just plain water.</p> <p>But micellar water products contain something called micelles – clusters of molecules that are <em>very</em> effective at removing oily substances. To understand why, you need to first know two chemistry terms: hydrophilic and hydrophobic.</p> <p>A hydrophilic substance “loves” water and mixes easily with it. Salt and sugar are examples.</p> <p>A hydrophobic substance “hates” water and generally refuses to mix with it. Examples include oil and wax.</p> <p>Hydrophilic materials will happily mix with other hydrophilic materials. The same goes for hydrophobic substances. But if you try to combine hydrophilic and hydrophobic materials, they won’t mix.</p> <h2>How are micelles formed? It’s all about surfactants</h2> <p>The micelles in micellar water are formed by special molecules known as surfactants.</p> <p>Surfactant stands for surface active agent. These molecules looked at their hydrophilic and hydrophobic brethren and said, why not both? They are typically comprised of two ends: a head group that is hydrophilic and a tail that is hydrophobic.</p> <p>When a small amount of surfactant is added to water, the two ends of the molecule have competing interests. The hydrophilic head wants to be in the water, but the hydrophobic tail can’t stand water.</p> <p>Add enough surfactant and, eventually, we will pass a critical micelle concentration and the surfactants will self-assemble into clusters of approximately 20 to 100 surfactant molecules.</p> <p>All the hydrophilic heads will be pointing outwards, while the hydrophobic tails remain “hidden” at the centre. These clusters are micelles.</p> <p>These micelles have a hydrophilic exterior, meaning that they are very happy to remain mixed throughout water. However, in the centre remains a hydrophobic pocket that’s very good at attracting oils.</p> <p>This is very handy, and helps explain why adding some detergent (a surfactant) to water will allow you to wash an oily saucepan. The surfactant first helps lift of the oil, and then the oil can remained mixed into the water, finding a new home in the hydrophobic centre of the micelle.</p> <figure><iframe src="https://www.youtube.com/embed/fnRBCn8fm2o?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Micellar water in action</h2> <p>Surfactants are in your dishwashing detergent, your body wash, your shampoo, your toothpaste and even many foods. In all of these cases, they are there to help the water interact with the dirt and oils, and micellar water is no different.</p> <p>When you apply some micellar water to a cotton pad, another convenient interaction occurs. The wet cotton is hydrophilic (loves water). Consequently, some of the micelles will unravel, with the hydrophilic heads being attracted to the wet cotton pad.</p> <p>Now, sticking out from the surface will be a layer of hydrophobic tail groups. These hydrophobic tails cannot wait to attract themselves to makeup, sunscreen, oils, dirt, grease and other contaminants on your face.</p> <p>As you sweep the cotton pad across your skin, these contaminants bind to the hydrophobic tails and are removed from the skin.</p> <p>Some contaminants will also find themselves encapsulated in the hydrophobic centres of the micelle.</p> <p>Either way, a cleaner surface is left behind.</p> <p>Look at how a cotton wipe soaked in micellar water cleans up a small oil spill, in comparison to water alone.</p> <figure><iframe src="https://www.youtube.com/embed/5Nge5FEiuYE?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>So why shouldn’t I just use dishwashing detergent to wash my face?</h2> <p>Technically, that would work as detergent does indeed contain lots of micelle-forming surfactants.</p> <p>But these particular surfactants would probably cause a lot of skin and eye irritation, while also damaging and drying out your skin. Not nice.</p> <p>The surfactants in micellar water are chosen to be mild and well tolerated by most people’s skin. But micellar water isn’t the only skincare product to contain micelles. There are many other face-cleaning products that also make great use of surfactant molecules and work very well too.</p> <p>Now, it’s not perfect. While it is effective at removing a wide range of contaminants, thick or heavy makeup might not come off easily with micellar water (you might need to do a more vigorous clean).</p> <p>Some products say there is “zero residue”, although the fine print clearly states this refers to visible residue.</p> <p>Many products also state there is no rinse off required. Surfactants will remain on your skin after product use, but for many people they don’t cause irritation. If your skin is feeling irritated after using a micellar water product, you can try rinsing afterwards or discontinuing use.</p> <p>And as is the case with many cosmetic products, you should test it first on a small patch of skin before using it all over your face.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/219492/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/daniel-eldridge-1494633"><em>Daniel Eldridge</em></a><em>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
