What are cooling blankets? Can they really help me sleep?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/luana-main-2270550">Luana Main</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>You wake up exhausted from yet another hot night of tossing and turning, with very little sleep.</p> <p>So you might be tempted to buy a “cooling blanket” after reading rave reviews on social media. Or you might have read online articles with <a href="https://www.news.com.au/checkout/home-and-garden/bedroom/bedding/best-cooling-blankets/news-story/118ce05eba1e7d5cdff3aeadae5ae940">taglines such as</a>:</p> <blockquote> <p>Stop waking up in a puddle of sweat with our roundup of the best cooling blankets – including a top-rated option from Amazon that ‘actually works’.</p> </blockquote> <p>But what are cooling blankets? And can they help you get a restful night?</p> <h2>We know a cooler bedroom is best</h2> <p>First, let’s look at why a cooler environment helps us sleep better at night.</p> <p>Our body’s internal temperature has a <a href="https://www.sleepfoundation.org/circadian-rhythm">circadian rhythm</a>, meaning it fluctuates throughout the day. A couple of hours before bed, it drops about <a href="https://www.sciencedirect.com/science/article/pii/S1087079203000236">0.31°C</a> to help you fall asleep. It will drop about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7323637/">another 2°C</a> across the night to help you stay asleep.</p> <p>During sleep, your internal temperature and skin work together to achieve a balance between losing and producing heat. Your skin has sensors that pick-up changes in the environment around you. If it gets too warm, these sensors let your body know, which may cause you to kick-off blankets or bed clothes and wake more often leading to poorer sleep quality.</p> <p><a href="https://www.thensf.org/what-is-sleep-quality/">Sleep quality</a> is an important component of sleep health ensuring you get the physical, mental and emotional benefits that come from a good night’s sleep.</p> <p>The <a href="https://www.sciencedirect.com/science/article/pii/S0360132318300325">ideal temperature</a> for sleep varies depending on the season and type of bedding you have but falls between 17°C and 28°C. Keeping your sleeping environment within this range will help you to get the best night’s rest.</p> <h2>So what are cooling blankets?</h2> <p>Cooling blankets are designed to help regulate your body temperature while you sleep.</p> <p>Different technologies and materials are used in their design and construction.</p> <p>We’re not talking about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2206487/">hospital-grade</a> cooling blankets that are used to reduce fever and prevent injury to the nervous system. These use gel pads with circulating water, or air-cooling systems, connected to automatic thermostats to monitor someone’s temperature.</p> <p>Instead, the type of consumer-grade cooling blankets you might see advertised use a blend of lightweight, breathable materials that draw moisture away from the skin to help you stay cool and dry through the night. They look like regular blankets.</p> <p>Common materials include cotton, bamboo, silk or the fibre <a href="https://goodonyou.eco/how-ethical-is-tencel/">Lyocell</a>, all of which absorb moisture.</p> <p>Manufacturers typically use a <a href="https://www.sleepfoundation.org/best-sheets/best-thread-count-for-sheets">thread count</a> of <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">300-500</a>, creating air pockets that enhance airflow and moisture evaporation.</p> <p>Some blankets feature a <a href="https://getrest.com.au/blogs/all/unveiling-the-secrets-of-q-max-the-key-to-a-perfect-nights-sleep">Q-Max rating</a>, which indicates how cool the fabric feels against your skin. The higher the value, the cooler the fabric feels.</p> <p>Others feature <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">phase change materials</a>. These materials were developed by <a href="https://spinoff.nasa.gov/Spinoff2009/ch_4.html">NASA</a> for space suits to keep astronauts comfortable during a spacewalk where temperatures are from roughly <a href="https://www.nasa.gov/humans-in-space/spacewalk-spacesuit-basics/">-157°C to 121°C</a>. Phase change materials in cooling blankets absorb and hold heat producing a cooling effect.</p> <h2>Do they work?</h2> <p>If you believe online reviews, yes, cooling blankets can cool you down and help you sleep better in warmer weather or if you get too hot using normal sheets and blankets.</p> <p>However, there is little scientific research to see if these consumer-grade products work.</p> <p>In a 2021 <a href="https://www.mdpi.com/2071-1050/13/16/9099">study</a> exploring sleep quality, 20 participants slept for three nights under two different conditions.</p> <p>First, they slept with regular bed sheets in an air-conditioned room with the temperature set to their preference. Then, they used cooling bed sheets in an air-conditioned room where the temperature was set 3°C higher than their preference.</p> <p>Participants reported good sleep quality in both conditions but preferred the warmer room with its cooling sheets.</p> <p>This may suggest the use of cooling bedding may help provide a more comfortable night’s sleep.</p> <p>But everyone’s cooling needs varies depending on things like age, health, body temperature, the space you sleep in, and personal preferences.</p> <p>So while these products may work for some people who may be motivated to leave a good review, they may not necessarily work for you.</p> <h2>Are they worth it?</h2> <p>There’s a wide variety of cooling blankets available at different prices to suit various budgets. Positive customer reviews might encourage a purchase, especially for individuals experiencing disrupted sleep at night due to heat.</p> <p>Yet, these cooling blankets have limited scientific research to show they work and to say if they’re worth it. So it’s up to you.</p> <h2>What else can I do if I’m a hot sleeper?</h2> <p>If a cooling blanket isn’t for you, there are other things you can do to stay cool at night, such as:</p> <ul> <li> <p>using air conditioning or a fan</p> </li> <li> <p>placing a damp towel under or over you</p> </li> <li> <p>wearing lightweight or minimal sleepwear and avoiding thick or synthetic fabrics, such as nylon, that can trap heat</p> </li> <li> <p>if you usually share a bed, on hot nights, consider sleeping by yourself to avoid excess body heat from your partner.</p> </li> </ul> <p>On a final note, if you often struggle with hot, disturbed sleep, you can check in with your health-care provider. They can see if there is a medical explanation for your disturbed sleep and advise what to try next.<!-- Below is The Conversation's page counter tag.

Do natural fabrics really keep us cooler in summer? Here’s the science

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>The Bureau of Meteorology has warned Australia is facing one of the <a href="https://www.abc.net.au/news/2024-10-12/australia-facing-one-of-hottest-summers-on-record-bom/104464014">hottest summers on record</a>. As the weather warms, many of us reach for light-coloured clothes in natural fabrics, such as cotton and linen.</p> <p>But why are natural fabrics like these so much better at keeping us cool when the weather is hot?</p> <p>Here’s what the science says.</p> <h2>Natural fabrics and sweat: a match made in heaven</h2> <p>In hot weather, we sweat. As sweat evaporates, it carries heat away, which helps cool the body down.</p> <p>In hot weather, then, we want clothes that help take moisture away from the body as efficiently as possible.</p> <p>Natural fabrics are made using fibres extracted from plant- or animal-based sources such as cotton, linen, hemp, wool and silk.</p> <p>The primary component of all plant-based fibres is cellulose. Animal-based fibres are made up of proteins such as keratin and silk fibroin.</p> <p>Cellulose molecules are rich in compounds called hydroxyl groups that attract water and moisture. In scientific terms, they are hydrophilic – they love water.</p> <p>So, clothing made of cotton and linen is highly hydrophilic. It tends to absorb moisture and disperse it across the fabric, allowing it to evaporate more easily.</p> <p>This takes the sweat away quickly, making it more comfortable and breathable and allowing us to stay cool in sweltering temperatures.</p> <p>One downside of the natural fabrics is they wrinkle quickly (some people, of course, like that look).</p> <p>And on a really hot, sweaty day, natural fabrics can get heavy and wet.</p> <p>Animal fibres are basically proteins, and their properties vary depending on the source.</p> <p>Wool has been bio-engineered over millions of years to be comfortable to wear. Wool fibres are hydrophilic on the inside and hydrophobic on the outside, meaning they’re both water resistant and good at wicking moisture away.</p> <p>On the other hand, silk fabrics are very good at helping regulate temperature; they keep us cool in hot weather and warm in cold weather.</p> <h2>Synthetic fabrics: less wrinkly, more sweaty</h2> <p>Synthetic fabrics, on the other hand, are lighter and tend to wrinkle less.</p> <p>Common synthetic fabrics (such as polyester, nylon and acrylic) are all made from petroleum-based chemicals.</p> <p>Most synthetic fibres are made of long chains of hydrogen and carbon atoms and do not contain the hydroxyl groups we discussed earlier.</p> <p>Such fibres are therefore hydrophobic – they hate water. This means the water can’t spread evenly across the fabric and evaporate easily.</p> <p>They trap sweat against the skin, making the clothes less breathable and comfortable when the weather is warm and humid.</p> <p>However, some synthetic fabrics used in certain types of active wear can wick sweat away from body.</p> <p>And some semi-synthetic fabrics such as rayon or tencel (which are made from wood pulp or cotton with synthetic fibres) are more breathable than other synthetic fabrics such as polyester or nylon.</p> <h2>Fabric weave makes a difference, too</h2> <p>The colour of the clothing is also a contributing factor to keep you cool during summer. Light colours reflect sunlight away from you and help to keep the body cooler.</p> <p>There is some evidence dark colours absorb the <a href="https://www.sciencedirect.com/science/article/pii/S2214157X23012054">sunlight and associated heat</a>, making the surface of the skin warmer than normal.</p> <p>Another factor affecting breathability and comfort of clothing is the way the fabrics are woven.</p> <p>Fabrics that are loosely woven (sometimes known as “open weave”) with thinner materials naturally have more airflow, which helps you keep cool.</p> <p>For a quick, non-scientific test, hold a fabric up and see how much light passes through it. The more light you can see, the more breathable it likely is.</p> <p>The way the fabric is treated can play a role, too; such as for softening and wrinkle resistance.</p> <p>Using a fabric softener when you do a load of laundry usually doesn’t affect fabric breathability; softeners modify the surface of the fabric but don’t change the internal structure or porous nature of the fabrics.</p> <p>Wrinkle resistance is the ability of the fabric to stay smooth and polished even after washing. Synthetic fabrics are inherently wrinkle resistant. Natural fibres are more prone to wrinkles but can be chemically treated on the fabric surface during manufacturing to make them wrinkle resistant.</p> <p>Such treatments, however, may form layers on top of the fabric blocking the airflow, leading them to be less breathable.<!-- Below is The Conversation's page counter tag.

When a casual punt turns into addictive gambling – how to ensure it won’t really cost you

<p>Gambling is a real and growing problem. Left unchecked, the occasional punt can quickly develop into an addiction, with devastating effects on finances and relationships. Debts can spiral and the stress causes marriages to fail and other relationships to splinter.</p> <p><a href="https://www.monash.edu/medicine/news/latest/2022-articles/gambling-and-homelessness-a-growing-problem-amongst-older-australians">Research published in 2022 by Monash University</a> also found that gambling and homelessness are “interconnected”, singling out senior Australians as most in the firing line.</p> <p>Before things devolve to that level, consider these steps for putting boundaries around your – or your partner’s – gambling.</p> <p><strong>Remember: Big business is big for a reason</strong></p> <p>In 2023, the <a href="https://www.aihw.gov.au/reports/australias-welfare/gambling">Australian Institute of Health and Welfare (AIHW)</a> noted that “Australians lose approximately $25 billion on legal forms of gambling each year, representing the largest per capita losses in the world”. That equates to every single Aussie losing $909 annually. </p> <p>The reality is these companies exist to make money – and skew the odds in their favour, not yours. Keep that in mind the next time you’re tempted to try your “luck”.</p> <p><strong>Stay active</strong></p> <p>For some people, especially retirees, gambling becomes something to pass the time and get them out of the house. </p> <p>However, you needn’t gamble your money away to keep boredom at bay. There are healthier and more productive ways to do this. </p> <p>For example, there are a myriad of social, sporting, and recreational groups for seniors and retirees. A lack of work commitments offers the flexibility to indulge in travel, both within Australia and overseas. Take the opportunity to socialise with friends and family. Turn your hobby or side hustle into a proper business. Or get a dog you can take for long walks. The possibilities are endless…</p> <p><strong>Don’t punt with what you can’t afford to lose</strong></p> <p>Gambling with a bit of money you have specifically put aside for leisure activities is one thing; gambling your life savings or money needed for essentials like food, bills and keeping a roof over your head is quite another. </p> <p>Having lost that essential money, problem gamblers often become desperate to try and win it back – begging, borrowing or even stealing more, with the repercussions quickly spiralling out of control as that money is often lost too.</p> <p>If you must gamble, only gamble what you can afford to lose: have a budgeted amount and stick to it no matter what. Anyone who deep-down knows they aren’t disciplined with their money would be wise to think twice altogether.</p> <p><strong>Never borrow to gamble</strong></p> <p>As a rule of thumb, money that comes with a cost attached to it should only ever be spent on things that will make more money in the long run, like buying a home or investing. </p> <p>When it comes to gambling, always use your free cash. Money you have borrowed, redrawn from your home loan, or racked up on your credit card will have to be repaid eventually – with interest on top.</p> <p><strong>Choose a place and a time</strong></p> <p>“Most people using gambling machines are older Australians,” <a href="https://www.monash.edu/medicine/news/latest/2022-articles/gambling-and-homelessness-a-growing-problem-amongst-older-australians">Monash University’s Associate Professor Charles Livingstone says</a>. This type of gambling is where things can easily turn sinister.</p> <p>To help keep things in check, limit your gambling to special occasions or events. That might be a flutter on the Melbourne Cup, a game of two-up on ANZAC Day, or a Lotto ticket as a birthday treat. It will mean more if it is tied to something special and an experience you can share with loved ones. Which leads into our next point:</p> <p><strong>Avoid gambling alone</strong></p> <p>Gambling by yourself can be a recipe for disaster. You don’t have a second pair of eyes over what you are doing or that trusted person to step in and say, ‘that’s enough’. </p> <p>In fact, I recommend couples always take a joint approach to their finances, regardless of whether gambling is involved. Leaving all the “money stuff” up to one of you means less accountability and opens the door for shared money and assets to be used improperly.</p> <p><strong>Ask for help</strong></p> <p>If you recognise things are getting out of hand, don’t suffer in silence. </p> <p>Talk things through with your partner, adult children or a trusted friend. Alternatively, contact <a href="https://www.gamblinghelponline.org.au/">Gambling Help Online</a> (1800 858 858) for free support 24/7 right across Australia.</p> <p>The sooner you get help, the faster you can limit the fallout and get things back under control!</p> <p><em><strong>Helen Baker is a licensed Australian financial adviser and author of On Your Own Two Feet: The Essential Guide to Financial Independence for all Women. Helen is among the 1% of financial planners who hold a master’s degree in the field.

The anatomy of a hot flush – and whether it can really make your head steam

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/michelle-spear-172043">Michelle Spear</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>A hot flush is a phenomenon as disruptive as it is commonplace. One moment, life proceeds as usual. The next, a wave of heat rises, spreading from the chest to the face – leaving behind flushed skin and beads of sweat. For many, this sudden warmth is accompanied by an <a href="https://www.mayoclinic.org/diseases-conditions/hot-flashes/symptoms-causes/syc-20352790">accelerated heartbeat and a faint sense of unease</a>. Though brief – typically lasting anywhere from 30 seconds to five minutes – its intensity can be startling and made worse by unpredictable timing.</p> <p>A recent viral video has brought attention to just how intense a hot flush can be. The video depicts a woman named Tracey Monique <a href="https://uk.style.yahoo.com/menopause-hot-flush-flash-symptoms-134536113.html?guccounter=1">experiencing a hot flush</a> while at an outdoor event. In the video, her head is literally steaming.</p> <p>The sight of wisps of vapour escaping her head highlighted the dramatic effects of this common <a href="https://www.nhs.uk/conditions/menopause/symptoms/">perimenopausal symptom</a>. Often misunderstood or trivialised, the image of a hot flush brings fresh attention to a phenomenon that affects an estimated <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/introduction-to-menopause">75% of people experiencing perimenopause</a>.</p> <p>The video has also sparked debate on social media – reflecting the complexity of hot flushes themselves. Some argue the steam escaping Monique’s head was caused by her removing her hat while being in the cold. But many women have commented, saying the video perfectly encapsulates what a hot flush feels like.</p> <p>Let’s take a look at what’s actually happening during a hot flush and why they can feel so severe.</p> <h2>Hormonal instigators</h2> <p>At the heart of a hot flush lies oestrogen – a hormone critical role in regulating body temperature in women. Oestrogen directly <a href="https://my.clevelandclinic.org/health/body/22566-hypothalamus">influences the hypothalamus</a>, a small but essential structure in the brain often referred to as the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6397692/">body’s thermostat</a>. The hypothalamus monitors and adjusts body temperature to maintain balance.</p> <p>Under normal circumstances, the hypothalamus keeps the body within a narrow temperature range – adjusting blood flow and sweat production as needed. But during perimenopause, <a href="https://www.rcog.org.uk/for-the-public/browse-our-patient-information/treatment-for-symptoms-of-the-menopause/?utm_source=chatgpt.com">oestrogen levels fluctuate</a> unpredictably and eventually decline. These hormonal shifts disrupt the hypothalamus’s ability to maintain its usual set temperature.</p> <p>Declining oestrogen levels also make the hypothalamus overly sensitive to small changes in body temperature – misinterpreting these as <a href="https://pubmed.ncbi.nlm.nih.gov/31001050/">signs of overheating</a>. This triggers an exaggerated response aimed at cooling the body down: a hot flush. The result is a sudden dilation of blood vessels, particularly in the skin of the upper body, to allow heat to radiate outward. Simultaneously, sweat glands activate – intensifying the sensation of heat.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3956631/">Luteinising hormone</a>, which primarily regulates ovulation, also plays a secondary role in hot flushes. As oestrogen levels decline, the pituitary gland (which regulates key hormones that control growth, reproduction and metabolism) <a href="https://academic.oup.com/endo/article/163/2/bqab268/6490154">releases erratic surges</a> of lutenising hormone. These spikes appear to further heighten the hypothalamus’s sensitivity, amplifying its misinterpretation of normal body temperature as overheating.</p> <h2>The cooling response</h2> <p>During a hot flush the hypothalamus sends urgent signals to the autonomic nervous system, which governs involuntary functions such as heart rate, blood pressure and sweating. This prompts blood vessels near the skin to dilate – a <a href="https://www.ncbi.nlm.nih.gov/books/NBK557562/">process called vasodilation</a>. This allows more blood to flow to the surface to release heat. This is why the face, neck and chest can feel intensely warm and look visibly flushed during a hot flush.</p> <p>Almost simultaneously, the hypothalamus activates sweat glands in the upper body. Sweating is meant to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6773238/">cool the body</a> through evaporation. In cold environments, this sweat may produce visible steam – as seen in Monique’s viral video.</p> <p>But once the hypothalamus realises the body isn’t actually overheated, vasodilation subsides and blood vessels return to their normal state. But the rapid cooling effect from sweating can leave women <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">feeling chilled</a>. This creates a rollercoaster of sensations during and after the hot flush.</p> <p>This sequence – heat, flush, sweat and chill – reflects the body’s struggle to regain equilibrium in response to a misfiring thermostat.</p> <h2>The debate</h2> <p>While the sensation of heat is undeniable, whether hot flushes significantly raise skin temperature remains debated.</p> <p><a href="https://www.maturitas.org/article/0378-5122(79)90009-4/abstract">Thermographic studies</a>, which use infrared imaging to measure heat patterns and surface temperature, have demonstrated measurable skin temperature rises – particularly in the face, neck and chest.</p> <p>But other research has found only <a href="https://www.obgproject.com/2019/07/24/are-menopausal-hot-flushes-really-triggered-by-core-temperature/">minor or negligible changes</a> in skin temperature. This raises questions about whether the perception of heat correlates directly with physiological changes.</p> <p>Critics suggest that the sensation of heat stems more from the brain’s altered thermoregulation than from actual warming of the skin. Tools such as thermographic imaging may also miss subtle or transient temperature changes – or these changes may be masked by sweat evaporation.</p> <p>It may also be the case that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">skin temperature changes</a>, like other perimenopausal symptoms, vary widely between people. The <a href="https://bmcwomenshealth.biomedcentral.com/articles/10.1186/1472-6874-9-13">variability in oestrogen levels</a> contributes significantly – with those experiencing more erratic hormonal changes often reporting more intense or frequent flushes. Factors such as <a href="https://www.mdpi.com/2072-6643/16/5/655">genetics, lifestyle and environmental triggers</a>, all add to the diversity of experiences and how intense symptoms might be.</p> <p>Hot flushes are a complex interplay of hormonal, neurological and vascular responses. While the scientific debate about skin temperature changes remains unresolved, the lived experience of heat and discomfort is undeniable. For many, these symptoms are disruptive and even debilitating, profoundly affecting daily life.</p> <p>Monique’s viral video, with the striking image of steam rising from her head, has resonated deeply with countless women – offering stark visual evidence of what they’ve felt but often struggled to articulate. Understanding the anatomy of a hot flush not only sheds light on its mechanisms but also underscores the importance of empathy and tailored approaches to managing this multifaceted symptom.<!-- Below is The Conversation's page counter tag.

"That's really spot on": Robert Irwin's tearful reaction to seeing his dad's wax figure

<p>Robert Irwin has made history as the youngest Australian ever to be immortalised in wax at Madame Tussauds Sydney.</p> <p>The 20-year-old conservationist unveiled his lifelike figure in an emotional ceremony today, which also marked his first encounter with the wax figure of his late father, Steve Irwin.</p> <p>Dressed in his iconic Australia Zoo khakis, Robert’s wax figure radiates his adventurous spirit, holding a Canon DSLR camera while a python drapes over the lens – a fitting tribute to his passion for wildlife photography and conservation.</p> <p>Sharing the milestone on social media, Irwin posted, “Caught up with my new mate today at Madame Tussaud’s Sydney… So SURREAL and such an honour! Grateful 🙏.”</p> <p>Speaking with <em>Sunrise</em>, Robert also reflected on the poignant moment of seeing his father’s wax figure in person for the first time.</p> <p>“It was the first time I’d ever got to see my dad’s wax figure. I’d seen pictures of it, but I’d never seen it in real life, and I was actually, I was overcome with emotion and I didn’t think that was going to happen,” he said.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/DC5Rk1xTC_v/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/DC5Rk1xTC_v/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by Robert Irwin (@robertirwinphotography)</a></p> </div> </blockquote> <p>Steve Irwin, the beloved “Crocodile Hunter” passed away in 2006, leaving behind a legacy of conservation and education.

What does a good death look like when you’re really old and ready to go?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/naomi-richards-182120">Naomi Richards</a>, <a href="https://theconversation.com/institutions/university-of-glasgow-1269">University of Glasgow</a></em></p> <p><a href="https://www.huffingtonpost.co.uk/entry/hawaii-legalizes-assisted-suicide_us_5ac6c6f5e4b0337ad1e621fb">Hawaii</a> recently joined the growing number of states and countries where doctor-assisted dying is legal. In these jurisdictions, help to die is rarely extended to those who don’t have a terminal illness. Yet, increasingly, very old people, without a terminal illness, who feel that they have lived too long, are arguing that they also have a right to such assistance.</p> <p>Media coverage of <a href="https://www.washingtonpost.com/news/to-your-health/wp/2018/05/09/this-104-year-old-plans-to-die-tomorrow-and-hopes-to-change-views-on-assisted-suicide/?utm_term=.b00a9036f9bc">David Goodall</a>, the 104-year-old Australian scientist who travelled to Switzerland for assisted dying, demonstrates the level of public interest in ethical dilemmas at the <a href="https://www.bmj.com/content/361/bmj.k1891.full">extremities of life</a>. Goodall wanted to die because he no longer enjoyed life. Shortly before his death, he told reporters that he spends most of his day just sitting. “What’s the use of that?” he asked.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0277953615002889?via%3Dihub">Research</a> shows that life can be a constant struggle for the very old, with social connections hard to sustain and health increasingly fragile. <a href="https://www.ncbi.nlm.nih.gov/pubmed/25982088">Studies</a> looking specifically at the motivation for assisted dying among the very old show that many feel a deep sense of loneliness, tiredness, an inability to express their individuality by taking part in activities that are important to them, and a hatred of dependency.</p> <p>Of the jurisdictions where assisted dying is legal, some make suffering the determinant (Canada, for example). Others require a prognosis of six months (California, for example). Mainly, though, the focus is on people who have a terminal illness because it is seen as less of an ethical problem to hasten the death of someone who is already dying than someone who is simply tired of life.</p> <h2>Why give precedence to physical suffering?</h2> <p>Assisted dying for people with psychological or existential reasons for wanting to end their life is unlikely to be supported by doctors because it is not objectively verifiable and also potentially remediable. In the Netherlands, despite the legal power to offer assistance where there is no life-limiting illness, doctors are <a href="https://www.ncbi.nlm.nih.gov/pubmed/25693947">seldom convinced</a> of the unbearable nature of non-physical suffering, and so will rarely administer a lethal dose in such cases.</p> <p>Although doctors may look to a physical diagnosis to give them confidence in their decision to hasten a patient’s death, physical symptoms are often not mentioned by the people they are assisting. Instead, the most common reason given by those who have received help to die is <a href="https://www.nejm.org/doi/full/10.1056/NEJMms1700606">loss of autonomy</a>. Other common reasons are to avoid burdening others and not being able to enjoy one’s life – the exact same reason given by Goodall. This suggests that requests from people with terminal illness, and from those who are just very old and ready to go, are not as different as both the law – and doctors’ interpretation of the law – claim them to be.</p> <h2>Sympathetic coverage</h2> <p>It seems that the general public does not draw a clear distinction either. Most of the media coverage of Goodall’s journey to Switzerland was sympathetic, to the dismay of <a href="http://www.carenotkilling.org.uk/press-releases/centenarians-assisted-suicide/">opponents</a> of assisted dying.</p> <p>Media reports about <a href="https://www.theguardian.com/tv-and-radio/2014/sep/02/mary-berry-great-british-bake-off-centenarian-assisted-dying">ageing celebrities</a> endorsing assisted dying in cases of both terminal illness and very old age, blur the distinction still further.</p> <p>One of the reasons for this categorical confusion is that, at root, this debate is about what a good death looks like, and this doesn’t rely on prognosis; it relies on <a href="https://www.tandfonline.com/doi/full/10.1080/01459740.2016.1255610">personality</a>. And, it’s worth remembering, the personalities of the very old are as diverse as those of the very young.</p> <p>Discussion of assisted suicide often focuses on concerns that some older people may be exposed to coercion by carers or family members. But older people also play another role in this debate. They make up the rank and file <a href="http://www.ep.liu.se/ej/ijal/2012/v7/i1/a01/ijal12v7i1a01.pdf">activists</a> of the global right-to-die movement. In this conflict of rights, protectionist impulses conflict with these older activists’ demands to die on their own terms and at a time of their own choosing.</p> <p>In light of the <a href="https://www.nih.gov/news-events/news-releases/worlds-older-population-grows-dramatically">unprecedented ageing</a> of the world’s population and increasing longevity, it is important to think about what a good death looks like in deep old age. In an era when more jurisdictions are passing laws to permit doctor-assisted dying, the choreographed death of a 104-year-old, who died listening to Ode to Joy after enjoying a last fish supper, starts to look like a socially approved good death.<!-- Below is The Conversation's page counter tag.

How are racehorses really treated in the ‘sport of kings’?

This care helps maximise the chance a horse will win races.</p> <p>Welfare is the animal’s subjective or individual experience of its life – <a href="https://pubmed.ncbi.nlm.nih.gov/33066335/">how it feels</a> – and there are a number of ways to assess this.</p> <p>One way is the concept of “telos”, originally developed by Ancient Greek philosopher <a href="https://plato.stanford.edu/entries/aristotle-causality/">Aristotle</a>.</p> <p>Telos is a <a href="https://link.springer.com/article/10.1007/s10806-012-9422-y">species’ anatomical, physiological, behavioural and cognitive characteristics</a> that have been shaped by millions of years of evolution.</p> <p>Telos helps us to identify what matters to animals – their behavioural, psychological and physiological needs.</p> <p>So to consider if racehorse care actually translates to good welfare, we can assess how closely it provides the animal with the things that matter to them, based on their telos.</p> <p>Equine telos involves living in groups, forming long-lived social relationships, grazing fibrous plants and being on the move for up to 18 hours a day, as well as staying safe by sensing danger and then moving away.</p> <p>It also involves living in variable environments to solve challenges, learn, engage in curiosity and play.</p> <p>Let’s compare that to the daily life of a racehorse.</p> <h2>Movement and feeding</h2> <p>Firstly, the vast majority of racehorses live in stables – sometimes up to 23 hours a day.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/17970632/">Multiple studies</a> have found continuous stabling harms horse welfare.</p> <p>Stables significantly restrict opportunities for voluntary movement, and studies show stabled horses spend <a href="https://pubmed.ncbi.nlm.nih.gov/37813129/">the majority of the time inactive</a>.</p> <p>Even though stables house horses communally, most designs limit horses’ opportunities for social interaction.</p> <p>Thirdly, there’s little for a horse to do in a stable other than eat, stand, drink or lie, and they often develop <a href="https://pubmed.ncbi.nlm.nih.gov/34670688/">abnormal behaviours</a> that are associated with stress. These are never seen in free-ranging horses.</p> <p>When racehorses do get to move, they have little say over how far, how fast and for how long they move.</p> <p>The kinds of physical exercise racehorses do are both significantly shorter in duration and at much higher speeds than horses voluntarily choose. It’s those speeds that place them at <a href="https://pubmed.ncbi.nlm.nih.gov/17910268/">risk of suffering a serious injury</a>.</p> <p>What about diet?</p> <p>Although a lot of time and effort is spent ensuring racehorses enjoy high quality diets, they are mostly comprised of concentrated energy sources such as grains, rather the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10135103/">fibre horses evolved to eat</a>.</p> <p>Horses are <a href="https://madbarn.com/slow-feeders-for-horses/#:%7E:text=Horses%20are%20trickle%20feeders%20that,to%2025%20miles%20per%20day.">trickle feeders</a> (grazers), with small stomachs that continuously secrete digestive juices.</p> <p>In the wild, grazing keeps those stomachs full, which prevents the stomach lining from being damaged by digestive acids.</p> <p>In comparison, racehorses often consume their food very quickly – instead of spending up to 75% of their day eating, <a href="https://www.sciencedirect.com/science/article/pii/B9780702026348500137">they spend only 33%</a>.</p> <p>This means their stomachs are empty for most of the day, which is why up to <a href="https://pubmed.ncbi.nlm.nih.gov/37048517/">65% will get painful gastric ulcers</a>.</p> <p>And having to wait to be fed rather than eating when hungry, as happens in free-ranging horses, <a href="https://www.mdpi.com/2076-2615/3/3/663">can lead to frustration</a>.</p> <h2>Other difficulties</h2> <p>Racehorses <a href="https://www.theage.com.au/national/does-whipping-hurt-race-horses-20211102-p595br.html">may be whipped</a>, and <a href="https://beva.onlinelibrary.wiley.com/doi/10.1111/j.2042-3306.1982.tb02389.x">more than 50% </a> will experience some form of musculoskeletal injury during racing, of which between <a href="https://www.mdpi.com/2076-2615/11/2/270">7-49% are fatal</a>.</p> <p>Social relationships, in the limited form possible in a racing stable, are also frequently disrupted because horse populations are highly transient due to spelling, <a href="https://theconversation.com/black-caviars-death-has-prompted-uncomfortable-questions-about-how-champion-mares-spend-their-retirement-237039">retirement</a> or even just going to the races.</p> <p>So even if two horses are able to form a relationship of sorts, chances are one will be taken away. <a href="https://pubmed.ncbi.nlm.nih.gov/?term=henshall+stress+repeated&amp;size=200">Separation distress is a significant stressor</a> for horses.</p> <p>Then there’s the gear that’s used to control them.</p> <p>Horses, like most animal species, escape and avoid painful stimuli.</p> <p>However, in racing (and many other equestrian activties) it is <a href="https://www.racingnsw.com.au/wp-content/uploads/NSWRules.pdf">mandatory to use</a> “bits” to control horses’ behaviour during riding and handling. Bits work by causing uncomfortable pressure and pain and may lead to mouth injuries.</p> <p>Studies have shown many people don’t understand how <a href="https://www.tandfonline.com/doi/full/10.1080/08927936.2023.2166713#abstract">to minimise the harm they can cause</a>. In addition, people also vary widely in their ability to read and <a href="https://www.mdpi.com/2076-2615/9/12/1124">interpret behavioural responses to stress</a>.</p> <p>So, racehorses may be repeatedly exposed to pain from bits and perform a range of behaviours to try to escape that pain, like bolting, mouth opening or head tossing.</p> <p>To remedy this, additional items of restrictive equipment, such as <a href="https://pubmed.ncbi.nlm.nih.gov/34056705/">tongue ties</a>, <a href="https://theconversation.com/dressing-up-for-melbourne-cup-day-from-a-racehorse-point-of-view-104771">nosebands, lugging bits or bit burs</a> may be used to control the horse.</p> <p>Racehorses frequently show signs of difficulty coping with the stressors of racing life, including “going off their feed”, aggression towards handlers, becoming hard to control when ridden and a range of stress behaviours and health issues, <a href="https://avmajournals.avma.org/downloadpdf/view/journals/javma/260/15/javma.22.08.0358.pdf">such as bleeding from the lungs</a>.</p> <h2>What about welfare?</h2> <p>Racehorse care is often directed towards managing issues that are the direct result of the demands of the racing environment.</p> <p>Fancy stables and aqua sessions are not important to horses, and may even cause harm.</p> <p>What matters to horses are opportunities to make meaningful choices, such as the freedom to move, form friendships and graze for the majority of the day.</p> <p>Current racing industry practices often deny horses the chance to make these choices.</p> <p>There’s no doubt people in racing care deeply about their horses. But to experience good welfare during racing, racehorses need more than just good care.<!-- Below is The Conversation's page counter tag.

“Is it really that bad?”: New mum slammed for baby name choice

<p>One woman has taken to social media to explain her dilemma after people around her made her second-guess the name she and her husband chose for their unborn son. </p> <p>The woman shared her situation on Reddit, and explained that the name has a special family significance to her, but so far people around her have absolutely hated it. </p> <p>"My grandpa was my favourite person in the whole world. Growing up, I always loved his name because I thought it was unique and I loved him. I always said if I had a son I would name him after my grandpa," she explained in the post. </p> <p>"Now I'm pregnant, and the very few people I've told the name to HATE IT. The name is Earl. Is it really that bad?"</p> <p>She added that she doesn't want her son to grow up hating his name, but she still wants to use it as it is so special to her. </p> <p>"Few other things: husband is on board and loves it, and it does sound really nice with our last name," she added. </p> <p>Many of the commenters urged her to go with the name if she loves it and to disregard what anyone else says. </p> <p>"This. Is. Your. Baby You don't need to poll the audience or tell anyone the baby's name before he is born. Protect your peace, and Earl's," replied one person. </p> <p> "I love Earl! Easy to say and spell. Uncommon but not made up. The emotional connection is wonderful too!" commented another. </p> <p>"It's a lovely name!!! Don't let other people shame you out of using it because you'll regret listening to them later," a third person assured her. </p> <p>"Earl is dated and country but it's cute and it means something to you and you both love it. It will be fine," another woman said. </p> <p>Some suggested that if she was really struggling with the name after the hate she received, there are other ways to incorporate it. </p> <p>"It's extremely dated but not bad. I personally think it's better as a middle name," replied one person. </p> <p><em>Image: Shutterstock</em></p> <p> </p>

Does eating ham, bacon and beef really increase your risk of developing type 2 diabetes?

This seems to have come from the <a href="https://www.cam.ac.uk/research/news/red-and-processed-meat-consumption-associated-with-higher-type-2-diabetes-risk">press release</a>, which used ham as the example to quantify the amount of processed meat associated with a 15% increased risk of developing type 2 diabetes over ten years.</p> <p>The research found that this risk was linked to eating an extra 50g of processed meat every day, which happens to equate to two slices of ham. A useful example thus appears to have been taken up by the media as the main cause, perhaps ignoring some of the key messages coming from the study.</p> <p>So, can processed and red meat really increase your risk of developing type 2 diabetes?</p> <p>The <a href="https://www.diabetes.org.uk/diabetes-the-basics/types-of-diabetes/type-2/diabetes-risk-factors">biggest risk factors</a> linked to developing type 2 diabetes are being over 40, having family members with type 2 diabetes, being of South Asian or African descent, or having a higher body weight – and especially a larger waist.</p> <figure><iframe src="https://www.youtube.com/embed/EsOBcx2bJqU?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The Cambridge study used data from nearly 2 million people from 31 studies. Participants were followed for an average of ten years. During this time, around one in 20 people developed type 2 diabetes.</p> <p>The research suggested that a 10% increase in the probability of developing type 2 diabetes was associated with every 100g of additional red meat eaten daily. Eating half as much extra processed meat every day was linked to an even greater increased risk of developing the disease.</p> <p>This is not the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66119-2/abstract">first time</a> that both processed and red meats have been linked with an increased risk of developing type 2 diabetes. However, the key strength of the Cambridge study was that it tried to control for many of the other factors linked to the disease, including smoking, having a higher body weight, dietary intake and exercise.</p> <p>However, the size of the increased risk is modest, considering few people included in the study ate 50g or more processed meat per day – meaning moderate ham consumption is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9908545/">no meaningful effect</a> on your risk.</p> <h2>What’s the link?</h2> <p>Processed meat has been linked to increased risk of type 2 diabetes because of its nitrate and salt content – additives that are used to cure many processed meats.</p> <p>Nitrates and salt in processed meats have also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893523/">been linked to</a> an increased risk of developing colon cancer. In fact, the World Health Organization classifies the additives as <a href="https://www.who.int/news-room/questions-and-answers/item/cancer-carcinogenicity-of-the-consumption-of-red-meat-and-processed-meat">group 1 carcinogens</a>, which means they can cause a range of cancers.</p> <p>The mechanism linking processed meat to cancer seems to be similar to how it might be linked to type 2 diabetes. During digestion, processed meat produces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6294997/">N-nitroso chemicals</a>, which can damage cells. This can lead to inflammation and affects how insulin, the hormone that controls blood glucose (sugar), works. This in turn can lead to <a href="https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance">insulin resistance</a>, when cells in your muscles, fat and liver don’t respond well to insulin and can’t easily take up glucose from your blood.</p> <p>Red meat, meanwhile, is <a href="https://www.healthline.com/nutrition/healthy-iron-rich-foods">rich in iron</a>. Research suggests that people with <a href="https://www.diabetes.org.uk/diabetes-the-basics/related-conditions/haemochromatosis-diabetes#:%7E:text=So%20a%20rise%20of%20iron,GP%20as%20soon%20as%20possible.">high levels of iron</a> are more likely to develop type 2 diabetes. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8744124/#:%7E:text=The%20WHO%20has%20recognised%20iron,being%20affected%20with%20this%20condition.">low levels of iron</a> are more of a health concern for the general population.</p> <p>Another potential link regarding red meat could be the way it is cooked.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5521980/">Previous studies</a> have suggested that charred meat, cooked over an open flame or at high temperature, is also linked to an increased risk of developing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911789/">type 2 diabetes</a>. Charring meat leads to formation of toxic chemicals such as <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/heterocyclic-amine#:%7E:text=Heterocyclic%20amines%20are%20aromatic%20compounds,of%20reactions%20called%20Maillard%20reactions.">heterocyclic aromatic amines</a> and harmful compounds like <a href="https://www.healthline.com/nutrition/advanced-glycation-end-products">advanced glycation end products</a>, both of which have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/21709297/">insulin resistance and type 2 diabetes</a>.</p> <h2>Bye-bye barbecues and bacon butties?</h2> <p>The key message is reduction, rather than avoidance. The UK government nutritional recommendations offer sound advice: limit your combined intake of red and processed meat to no more than <a href="https://www.nhs.uk/live-well/eat-well/food-types/meat-nutrition/#:%7E:text=Red%20meat%20and%20processed%20meat&amp;text=If%20you%20currently%20eat%20more,%2C%20veal%2C%20venison%20and%20goat.">an average of 70g per day</a>.</p> <p>But these guidelines also suggest that red meat can be a valuable source of iron. So, if you decide to stop eating red meat, you should eat alternative sources of iron such as beans, lentils, dark green vegetables and fortified cereals.</p> <p>This needs to be done as part of a carefully planned diet. Non-meat sources of iron are more difficult for our bodies to absorb so should be eaten with a source of vitamin C, found in green vegetables and citrus fruit.</p> <p>The best advice to reduce your risk of developing type 2 diabetes is to maintain a healthy weight – consider losing weight if you have a higher body weight – and be as physically active as possible.</p> <p>A healthy diet should be based on plenty of vegetables, fruit, beans, peas, lentils, nuts and seeds, along with some wholegrain foods, some dairy products, fish and white meat (or vegetarian alternatives) – plus moderate amounts of red meat and minimal processed meat. This will help reduce your risk of type 2 diabetes, <a href="https://www.bhf.org.uk/informationsupport/support/healthy-living/healthy-eating">heart disease</a>, and <a href="https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/does-having-a-healthy-diet-reduce-my-risk-of-cancer">many cancers</a> – as well being more <a href="https://www.bda.uk.com/static/539e2268-7991-4d24-b9ee867c1b2808fc/a1283104-a0dd-476b-bda723452ae93870/one%20blue%20dot%20reference%20guide.pdf">environmentally sustainable</a>.</p> <p>But if you have a penchant for ham sandwiches, rest assured you can continue to indulge as an occasional treat. It’s your overall lifestyle and diet that really matter for your health and risk of developing type 2 diabetes.<!-- Below is The Conversation's page counter tag.

All the reasons a cup of coffee really can be good for you

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/justin-stebbing-1405462">Justin Stebbing</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>Consuming too much caffeine is definitely bad for your health, and there may be good reasons why some people want to <a href="https://theconversation.com/caffeine-heres-how-quitting-can-benefit-your-health-220746">quit it altogether</a>. But if you despair at the idea of giving up your morning coffee, fear not.</p> <p>There’s lots of research out there to show that moderate coffee intake is linked with all sorts of benefits. As well as well-known pluses improving heart health, a daily cup of coffee even seems to be good for your brain and may help prevent mental illness.</p> <p>For a start, coffee contains several essential nutrients beneficial to <a href="https://pubmed.ncbi.nlm.nih.gov/37764216/">overall health</a>. A typical eight-ounce cup of coffee provides small amounts of B <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8073624/">vitamins</a> – riboflavin, pantothenic acid, thiamine and niacin – as well as minerals <a href="https://pubmed.ncbi.nlm.nih.gov/25415479/">potassium, manganese, and magnesium</a>. The nutrients in coffee can contribute significantly to daily intake when multiple cups are consumed.</p> <p>It’s also rich in <a href="https://pubmed.ncbi.nlm.nih.gov/36361861/">antioxidants</a>. In fact, many people – especially in the west – will probably get more antioxidants from coffee than from fruit and vegetables.</p> <p>So what does drinking coffee actually mean for the body? One of the most <a href="https://www.ncbi.nlm.nih.gov/books/NBK209050/">well-known</a> potential benefits of coffee is its ability to <a href="https://theconversation.com/nope-coffee-wont-give-you-extra-energy-itll-just-borrow-a-bit-that-youll-pay-for-later-197897">boost energy levels</a> and improve mental <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5608989/">alertness</a>, especially first thing in the morning or during an afternoon slump.</p> <p>This is primarily due to caffeine, a natural stimulant found in coffee, which blocks the brain’s <a href="https://www.news-medical.net/health/What-is-Adenosine.aspx#:%7E:text=In%20the%20brain%20adenosine%20is,the%20brain%20rise%20each%20hour.">inhibitory neurotransmitter adenosine</a>, which promotes sleep and suppresses arousal. This leads to increased neuronal firing and the <a href="https://pubmed.ncbi.nlm.nih.gov/1356551/">release</a> of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4462609/">neurotransmitters</a> like <a href="https://www.ncbi.nlm.nih.gov/books/NBK223808/">dopamine</a> and <a href="https://www.ncbi.nlm.nih.gov/books/NBK537259/">norepinephrine</a>, which enhance mood, reaction time and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8202818/">cognitive function</a>.</p> <p>However, sometimes it’s difficult to work out cause and effect here. People drink coffee at work, for example, and in social settings with friends so research has to tease out the effects of the coffee and those of the social aspect of sharing time with friends and colleagues.</p> <figure><iframe src="https://www.youtube.com/embed/I9xzgV7z1Bg?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Chronic diseases</h2> <p>In the long term, moderate coffee consumption can help reduce your risk of developing a host of chronic diseases.</p> <p><strong>1. Cardiovascular diseases</strong></p> <p>Moderate coffee consumption is associated with a reduced risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10262944/">heart disease and stroke</a>. Studies indicate that drinking one to two cups of coffee daily may lower the risk of heart failure. Additionally, <a href="https://www.acc.org/About-ACC/Press-Releases/2022/03/23/17/55/Good-News-for-Coffee-Lovers-Daily-Coffee-May-Benefit-the-Heart">coffee consumption</a> has been linked to a lower risk of cardiovascular mortality and disease. Interestingly, even when someone has abnormal heart rhythms, <a href="https://www.heart.org/en/news/2024/03/01/can-people-with-an-irregular-heartbeat-drink-coffee">coffee is not harmful</a> according to <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2204737">recent</a> data.</p> <p><strong>2. Type 2 diabetes</strong></p> <p>Coffee may enhance the body’s ability to process glucose, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0939475321002374">reducing the risk</a> of developing type 2 diabetes. Research has shown that people who consume more coffee have a <a href="https://www.healthline.com/health/coffee-s-effect-diabetes">lower likelihood</a> of developing this condition.</p> <p><strong>3. Liver diseases</strong></p> <p>Coffee seems to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5440772/">help protect</a> the liver appears to have protective. Both regular and decaffeinated coffee have been associated with healthier liver enzyme levels, and coffee drinkers have a <a href="https://britishlivertrust.org.uk/coffee-report/">significantly lower risk</a> of liver cirrhosis and liver cancer.</p> <p><strong>4. Cancer</strong></p> <p>Coffee consumption has been linked to a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9916720/">reduced risk</a> of several other types of cancer, including colorectal and womb cancers. A systematic review found that high coffee consumption is associated with an 18% lower risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696634/">cancer</a>.</p> <p><strong>5. Neurodegenerative diseases</strong></p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7773776/">Caffeine</a> is associated with a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7353179/">lower risk</a> of developing Parkinson’s disease and may help those with the condition manage their movements better. Additionally, coffee consumption may reduce the risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5690364/">Alzheimer’s disease</a> and other forms of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7478584/">dementia</a>.</p> <h2>Mental health</h2> <p>As if the physical benefits aren’t enough, coffee has also been shown to have <a href="https://www.webmd.com/mental-health/news/20230915/moderate-coffee-intake-lowers-risk-of-anxiety--depression">positive</a> effects on <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8467199/">mental health</a>. Studies suggest that coffee drinkers have a lower risk of depression, with some findings indicating a 20% reduced risk of becoming depressed.</p> <p>What’s more, coffee consumption has been associated with a decreased risk of suicide. Research has found that people who drink four or more cups a day are 53% less likely to commit <a href="https://pubmed.ncbi.nlm.nih.gov/23819683/">suicide</a>.</p> <figure><iframe src="https://www.youtube.com/embed/62wEk02YKs0?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Lifespan</h2> <p>With all these benefits, it’s not surprising that <a href="https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2686145">research suggests</a> that coffee drinkers tend to live longer than non-drinkers. A large study involving over 400,000 people found that coffee consumption over a period of 12 to 13 years was linked to a lower risk of death – with the strongest effect observed at four to five cups per day.</p> <p>This longevity <a href="https://www.nejm.org/doi/pdf/10.1056/NEJMoa1112010">benefit</a> could be due to the cumulative effects of coffee’s protective properties against various diseases.</p> <h2>Moderation required</h2> <p>While coffee offers numerous <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696634/">health benefits</a>, it is essential to consume it in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696634/">moderation</a>. It’s also advisable to limit added sugars and creams to avoid unnecessary calorie intake.</p> <p><a href="https://www.healthline.com/nutrition/caffeine-side-effects">Excessive caffeine</a> intake can lead to negative side effects such as jitteriness, anxiety and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6292246/">sleep disturbances</a>. Some people who are especially sensitive to caffeine may need to limit their coffee intake or avoid it altogether, as even decaffeinated coffee <a href="https://www.healthline.com/nutrition/caffeine-in-decaf">contains caffeine</a>.</p> <p>As with any dietary component, balance is key. By understanding the potential benefits and limitations of coffee, people can make informed decisions about incorporating it into their daily routine.</p> <p>I, for one, will be sticking to my morning cup.<!-- Below is The Conversation's page counter tag.

Does free-to-air TV really need gambling ads to survive?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/andrew-hughes-2728">Andrew Hughes</a>, <a href="https://theconversation.com/institutions/australian-national-university-877">Australian National University</a></em></p> <p>If anything is a sure bet right now, it’s corporate Australia’s willingness to use some variation of the “for society’s good” argument.</p> <p>The most recent example of this is the claim being made, including by federal minister <a href="https://www.theguardian.com/australia-news/article/2024/aug/13/gambling-ad-ban-labor-bill-shorten-tv-media-advertising-revenue">Bill Shorten</a>, that an outright ban on gambling advertising would be disastrous for free-to-air TV.</p> <p>To be clear, Labor still supports new restrictions on gambling advertisements, including hourly caps and bans during kids’ TV and during and around sports broadcasts.</p> <p>But it has rejected the idea of a total ban, prompting a <a href="https://www.smh.com.au/politics/federal/labor-mps-say-total-ban-is-the-only-way-on-gambling-ads-20240812-p5k1q0.html">backlash</a> extending as far as some of its own backbench MPs.</p> <p>Speaking on ABC’s Q&A on Monday night, Shorten said Australia’s free-to-air TV broadcasters were in “diabolical trouble”, with many needing gambling ad revenue “in order just to stay afloat”.</p> <p>“I’m not convinced that complete prohibition works,” he said.</p> <p>So would our commercial TV networks really fall over tomorrow without gambling ad revenue? Or is something else at play?</p> <h2>Who is buying ads in Australia?</h2> <p>Let’s start by building a bigger picture of where advertising spend more broadly comes from in Australia. Global analytics firm Nielsen regularly compiles <a href="https://www.nielsen.com/news-center/2024/top-20-categories-by-ad-spend-for-2023-revealed-in-latest-nielsen-ad-intel-report/#:%7E:text=Retail%20topped%20the%20list%20with,significant%20investment%20of%20%24596m.">top 20</a> lists of both the categories and individual companies spending the most on ads here.</p> <p>In 2023 the top category, retail, accounted for A$2.56 billion in advertising spend. Gambling and gaming, in contrast, represented just $239 million, less than a tenth of this figure.</p> <p>Harvey Norman topped the list of <a href="https://www.nielsen.com/news-center/2024/australias-top-20-highest-spending-advertisers-of-2023-revealed-in-latest-nielsen-ad-intel-report/">individual companies</a> in 2023. The first we see of any gambling brand is Sportsbet, which came in at 16th.</p> <p>For gambling companies, it’s fair to assume the lion’s share of this goes to TV. <a href="https://www.acma.gov.au/publications/2023-10/report/gambling-advertising-australia-placement-and-spending">Research</a> by the Australian Communications and Media Authority (ACMA) found 68% of gambling companies’ ad spend went to free-to-air TV markets.</p> <p>As for the remainder, 9% went to radio, 15% to social media and 8% to other online platforms.</p> <h2>How much is actually getting spent?</h2> <p>But how do we estimate the gambling industry’s total annual advertising spend? There are certainly a lot of numbers getting thrown around.</p> <p>One <a href="https://www.afr.com/companies/media-and-marketing/tv-networks-to-demand-fee-relief-as-40m-wagering-hole-opens-up-20240804-p5jzav">source</a> put it at $300.5 million for 2022.</p> <p>More recently, ACMA published detailed figures for the period between May 2022 and April 2023 which put it at just over <a href="https://www.acma.gov.au/publications/2023-10/report/gambling-advertising-australia-placement-and-spending">$238 million</a>, with $162 million of this going to free-to-air TV networks.</p> <p>But the way advertising is classified – what defines an advertisement – can sometimes differ between agencies. Then there is the <a href="https://www.acma.gov.au/check-if-gambling-operator-legal#register-licensed-gambling">number of brands operating</a>, which is constantly changing.</p> <p>In a market with so many competitors, any new entrant needs to spend big on advertising just to capture enough market share to be viable.</p> <p>This is why I argue that the actual figure for financial year 2023 may be slightly higher than ACMA’s widely quoted figure, accounting for the big ad spend of new entrants that may have fallen outside the time window assessed.</p> <p>Based on average company ad spend as a percentage of revenue and the size of the gambling industry, I estimate it could be higher, in the ballpark of $275 million.</p> <h2>How much is that to the networks?</h2> <p>This exercise is all about putting these figures in context.</p> <p>Channel Seven, for example, brought in <a href="https://www.sevenwestmedia.com.au/assets/Uploads/Final-2023-Annual-Report.pdf">$1.5 billion in revenue in 2023</a>. Even if it had received the gambling industry’s entire ad spend at my higher estimate of $275 million, this would still only account for less than 20% of its annual turnover.</p> <p>If that money all went to TV ads, Channel Seven’s stated 38.5% share of television advertising revenue would put its revenue from the estimated sports betting advertising at about $106 million in this example, around 7% of its total annual revenue.</p> <p>Losing most of that would hurt, but wouldn’t mortally threaten the business.</p> <p>A total ban would most likely be <a href="https://www.abc.net.au/news/2024-08-13/peta-murphy-left-online-gambling-legacy-why-isn-t-labor-adopting/104217328">phased in</a> over a number of years, not enacted overnight.</p> <p>Australia’s free-to-air networks would adapt, restrategise, and find and develop new markets to replace that revenue. Their management teams are far too smart to just shrug their shoulders and take a revenue hit on the corporate chin.</p> <h2>Networks have had plenty of time to adapt</h2> <p>Just a refresher. LinkedIn is now more than 20 years old. Facebook is 20. YouTube is 19. X (formerly known as Twitter) is 18. TikTok is seven.</p> <p>If free-to-air TV’s business model is so glacial it can’t function in the digital age, it probably doesn’t deserve to be operating in the big leagues.</p> <p>Digital is here and has been for a while now.

"Really unexpected": Lisa McCune opens up on Dancing With The Stars win

<p>Lisa McCune has opened up about her journey on <em>Dancing With The Stars</em> following her "unexpected" <a href="https://oversixty.com.au/entertainment/tv/dancing-with-the-stars-champion-crowned" target="_blank" rel="noopener">win</a>. </p> <p>Monday night's finale of the show saw Lisa McCune and her dancing partner Ian Waite took home the mirrorball trophy against finalists Ant Middleton, James Stewart, Nikki Osborne, and Samantha Jade.</p> <p>After the win, McCune told <a href="https://7news.com.au/entertainment/celebrity/lisa-mccune-spills-on-unexpected-dancing-with-the-stars-win-c-15683539" target="_blank" rel="noopener"><em>7News</em></a> that she was as shocked by the win as viewers were. </p> <p>“It really was unexpected,” McCune said. </p> <p>The actress added that she was extra thrilled for her dancing partner Ian Waite who has now taken out the Mirrorball Trophy for the first time.</p> <p>The win comes weeks after the gruelling <em>DWTS</em> process, which she admitted was more involved than she originally thought.</p> <p>“My agent said to me that somebody else had told them how difficult it was. And I thought, ‘Well, I probably needed a bit of a kick up the bum to do a bit more exercise’,” she says.</p> <p>“So I thought, ‘Well, it’d be good for me’. I started and I pretty quickly realised that the techniques involved and the different disciplines is pretty intense."</p> <p>“I think you underestimate how aerobically fit you actually need to be. But I gave it a red-hot go, and we had a really good time.”</p> <p>While McCune knew she did well through the competition, she said "Watching it back, I couldn’t recall any of the scores that we got because when you’re in the moment your adrenaline is kind of heightened, and (it’s like) watching it fresh.”</p> <p>As part of being crowned the<em> Dancing With The Stars</em> champion, Lisa was awarded $20,000 for her chosen charities: the RCD Foundation and the Harrison Riedel Foundation.</p> <div> </div> <p>“Both the charities I have a personal connection to in my local area, based on Victoria, both of them headed up by two amazing mums. These initiatives are spectacular.”</p> <p><em>Image credits: Instagram / Seven </em></p>

"Really upsetting": Man turned away from concert for being in a wheelchair

<p>A man from Melbourne has been left devastated after he was denied entry into a concert due to being a wheelchair. </p> <p>Dylan Taylor and his friends arrived at the Pier Bandroom in the suburb of Frankston to see one of his favourite heavy metal bands Polaris, when he ran into problems getting in the door. </p> <p>“I got to the front of the line, and they were checking IDs like normal, and one of the bouncers wouldn’t even acknowledge that I was there,” Taylor told <em><a href="https://7news.com.au/news/dylan-was-turned-away-from-seeing-his-favourite-band-because-he-uses-a-wheelchair-experts-say-its-a-common-issue-c-15618393" target="_blank" rel="noopener">7News</a></em>.</p> <p>“I was holding up my licence, and he wouldn’t look at it or take it, and they had taken everyone else’s licence."</p> <p>“I hadn’t really figured it out at this point ... but then the other bouncer said: ‘Nup, sorry mate, no wheelchairs’.”</p> <p>Taylor’s group of friends called for a manager to discuss the potential for them to “make it work”.</p> <p>The group was asked to wait around the side of the building for the manager, who was unable to offer any solutions. </p> <p>Dylan said he was told it would be a fire safety risk to let him in, and that even though in a scenario where a person injured in the venue would be carried out by bouncers during a fire, that the bouncers would not carry a wheelchair user out in the same scenario.</p> <p>“I’m spewin’ because, at this point, I haven’t even paid my friends back for the ticket, and I’ve ruined their night out,” he said.</p> <p>His friends continued to try to reason with the manager to let Dylan in, even saying they had seen a wheelchair user in the venue two weeks earlier, but to no avail.</p> <p>“Technically, you can have wheelchairs, but you have to be ambulant, that’s what we got out of them, in the end,” Taylor said.</p> <p>According to Dylan, there was no wheelchair access disclaimer on his tickets, nor on the Pier Bandroom’s website or social media, with Google Maps even displaying an accessibility widget which claimed there was a “wheelchair-accessible entrance”.</p> <p>A spokesperson from the Pier Bandroom parent company Endeavour Group told <em>7News</em> it was sorry for the distress caused by the incident.</p> <p>“The Pier Hotel was originally built in the 1800s and is a historic landmark in Frankston. While the Pier Hotel has various rooms on the ground floor, the Pier Bandroom function space is only accessible by stairs, and is not wheelchair accessible,” it said.</p> <p>“We apologise to any ticket holders who were not given adequate information about our venue’s policies at the time of purchasing tickets to recent concerts. We regret any inconvenience or distress this may have caused.</p> <p>“We are taking action to update the Pier Bandroom’s website with this information and communicate with any show promoters to do the same.”</p> <p>Taylor said the incident at the Pier Bandroom “was the first time I’ve faced, I would say, pretty blatant discrimination”, as he has only required the wheelchair for 18 months after sustaining a permanent spine injury. </p> <p>“You feel pretty empty inside, and I did have a little cry in the car on the way home."</p> <p>“It just really upsets me thinking about people who have maybe been dealing with disability for their whole life. Who maybe haven’t had the other half of life I’ve had, to be able to go and experience these things before being in a wheelchair.”</p> <p>While learning to live with his disability, Taylor was pleased to learn “how many people will go out of their way to help you out” but said it was disappointing to discover just how much his autonomy was curbed by poor accessibility.</p> <p>“It’s been a steep learning curve,” Taylor said.</p> <p>“Melbourne will accept the reputation of being inclusive and accepting, but it’s not necessarily accessible.”</p> <p><em>Image credits: Google Maps / 7News / Dylan Taylor </em></p>

However, it was not until 1979 that the right of women to participate in sport was formally included in the first international convention (United Nations) on <a href="https://www.ohchr.org/Documents/ProfessionalInterest/cedaw.pdf">the elimination of all forms of discrimination</a> against women.</p> <p>It took another 33 years for women to be allowed to <a href="https://library.olympics.com/default/zoom-femme-et-sport.aspx?_lg=en-GB">compete in all events</a> on the Olympic program in 2012.</p> <p>At the Paris Olympics, <a href="https://www.statista.com/statistics/1090616/olympics-share-athletes-by-gender-since-1896/">50% of competing athletes are women</a>, and the Australian team has its <a href="https://www.health.gov.au/ministers/the-hon-anika-wells-mp/media/australia-supports-unesco-push-for-gender-equality-in-sport?language=en">highest ever proportion of women (55%)</a>.</p> <h2>Women’s visibility</h2> <p>The IOC has been working hard at shaking off its patriarchal reputation for the past three decades or so.</p> <p>Two major milestones were the establishment of the <a href="https://olympics.com/ioc/gender-equality/gender-equality-through-time">Women and Sport Working Group</a> in 1995, and the <a href="https://www.europarl.europa.eu/RegData/etudes/BRIE/2019/635560/EPRS_BRI(2019)635560_EN.pdf">amending of the Olympic Charter</a> a year later to include advancing women in sport as an Olympic principle.</p> <p>Despite this progress, women’s Olympic events have often been <a href="https://revista-apunts.com/en/media-representation-of-women-athletes-at-the-olympic-games-a-systematic-review/">sidelined by the media</a>, enabling male athletes to enjoy greater publicity (and associated sponsorship) than their female counterparts.</p> <p>The long-established scheduling of events <a href="https://www.jou.ufl.edu/insights/gender-based-sports-coverage-a-quarter-century-of-prime-time-summer-olympics/">offers male athletes peak viewing times</a> across the globe, thereby consigning many women to the margins.</p> <p>In Paris, this <a href="https://olympics.com/ioc/news/genderequalolympics-paris-2024-making-history-on-the-field-of-play">gender discrimination</a> has been disrupted to better the balance.</p> <p>Combat and strength sports are now based on weight categories, permitting the women’s and men’s events to alternate instead of having men’s events available in the popular evening slot.</p> <p>The women’s marathon – only introduced to the Olympics in 1984 – will <a href="https://worldathletics.org/news/news/key-information-athletics-paris-2024-olympic-games">also conclude the athletics program</a> instead of the men’s for the first time.</p> <h2>Media representation</h2> <p>Amplifying women’s voices and stories from the games has been a key objective for the Paris Olympics.</p> <p>The IOC has been instrumental in this endeavour via its <a href="https://olympics.com/ioc/gender-equality/portrayal-guidelines">2024 Portrayal Guidelines:</a> gender-equal, fair and inclusive representation in sport.</p> <p>These guidelines have led to a large increase in the number of female staff in broadcast roles and production teams in Paris.</p> <p>And <a href="https://olympics.com/ioc/news/olympic-broadcasting-more-women-in-key-broadcast-roles-at-paris-2024">female-targeted training camps</a> in 2023 provided by the Olympic Broadcasting Services (OBS) have been a timely institutional transformation.</p> <p>Improved media representation of female athletes is also a priority, focusing on how they are visually captured and presented in all forms of media and communication.</p> <p>This helps to reframe persistent patriarchal narratives about how sportswomen must <a href="https://theconversation.com/uniform-discontent-how-women-athletes-are-taking-control-of-their-sporting-outfits-164946">maintain their femininity</a> to be worthy recipients of the <a href="https://vc.bridgew.edu/cgi/viewcontent.cgi?article=1269&amp;context=grad_rev">male gaze</a>.</p> <p>Regrettably, this is still a work in progress for some commentators such as <a href="https://www.skynews.com.au/business/media/you-know-what-women-are-like-eurosport-commentator-bob-ballard-sacked-for-sexist-remark-after-australias-freestyle-relay-win/news-story/739bc7a0efaf9d7007250ab0c4313f15">Bob Bollard, whose recent sexist “makeup” remark</a> went viral when he was reporting on the gold medal win for the Australian women’s 4x100m freestyle relay team.</p> <p>After the Bollard incident, Yiannis Exarchos, the <a href="https://www.scmp.com/yp/discover/news/sports/article/3272286/paris-olympics-camera-operators-told-avoid-filming-women-sexist-way">OBS chief, swiftly reminded</a> mostly male camera operators to refrain from any sexist filming of female athletes.

There they mixed with strangers and made new friends.</p> <p>There is a famous story about what happened when the philosopher <a href="https://www.britannica.com/biography/Plato">Plato</a> (428/427-348/347 BC) stayed at Olympia for the games.</p> <p>Plato lived there with others who did not realise he was the celebrated philosopher and he made a good impression on them, as the Roman writer <a href="https://www.britannica.com/biography/Aelian#:%7E:text=Aelian%20(born%20c.,%22Honey%2Dtongued%22).">Claudius Aelian</a> (2nd/3rd century AD) <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">recalled</a>:</p> <blockquote> <p>The strangers were delighted by their chance encounter […] he had behaved towards them with modesty and simplicity and had proved himself able to win the confidence of anyone in his company.</p> </blockquote> <p>Later on, Plato invited his new friends to Athens and they were amazed to find out he was in fact the famous philosopher who was the student of <a href="https://www.britannica.com/biography/Socrates">Socrates</a>.</p> <p>It’s unclear how many people actually visited the ancient games each time they were held, although some modern scholars <a href="https://olympics.com/ioc/ancient-olympic-games/spectators">think</a> the number could have been as high as 50,000 in some years.</p> <h2>Watching the games</h2> <p>The Greek writer <a href="https://www.britannica.com/biography/Chariton-Greek-author">Chariton</a> (1st century AD) in his novel Callirhoe <a href="https://www.loebclassics.com/view/LCL481/1995/volume.xml">wrote</a> how athletes – who had often also made a long journey to get to the games – arrived at Olympia “with an escort of their supporters”.</p> <p>Athletes competed naked, and women were usually not permitted to watch.</p> <p>But there were some exceptions. For example a woman called Pherenice, who lived in the 4th century BC, was permitted to attend the Olympics as a spectator. As Claudius Aelian <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">explains</a>:</p> <blockquote> <p>Pherenice brought her son to the Olympic festival to compete. The presiding officials refused to admit her as a spectator but she spoke in public and justified her request by pointing out that her father and three brothers were Olympic victors, and she was bringing a son who was a competitor. She won over the assembly and she attended the Olympic festival.</p> </blockquote> <p>As the contest was held in the middle of summer, it was usually extremely hot. According to Claudius Aelian, some people <a href="https://www.loebclassics.com/view/LCL486/1997/volume.xml">thought</a> watching the Olympics under “the baking heat of the sun” was a “much more severe penalty” than having to do manual labour such as grinding grain.</p> <p>The site at Olympia also had problems with freshwater supply. According to the writer <a href="https://www.britannica.com/biography/Lucian">Lucian of Samosata</a> (2nd century AD), visitors to the games sometimes <a href="https://www.tertullian.org/rpearse/lucian/peregrinus.htm#:%7E:text=Coming%20at%20last,that%20same%20water!">died of thirst</a>.

Cranberry juice really can help with UTIs – and reduce reliance on antibiotics

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Cranberry juice has been <a href="https://www.ncbi.nlm.nih.gov/books/NBK92762/">used medicinally for centuries</a>. Our new research indicates it should be a normal aspect of urinary tract infection (UTI) management today.</p> <p>While some benefits of cranberry compounds for the prevention of UTIs have been suspected for <a href="https://theconversation.com/cranberry-juice-can-prevent-recurrent-utis-but-only-for-some-people-203926">some time</a>, it hasn’t been clear whether the benefits from cranberry juice were simply from drinking <a href="https://bjgp.org/content/70/692/e200">more fluid</a>, or something in the fruit itself.</p> <p>For our <a href="https://www.sciencedirect.com/science/article/pii/S2405456924001226">study</a>, published this week, we combined and collectively assessed 3,091 participants across more than 20 clinical trials.</p> <p>Our analysis indicates that increasing liquids reduces the rate of UTIs compared with no treatment, but cranberry in liquid form is even better at reducing UTIs and antibiotic use.</p> <h2>Are UTIs really that bad?</h2> <p>Urinary tract infections affect more than <a href="https://journals.sagepub.com/doi/pdf/10.1177/1756287219832172">50% of women</a> and <a href="https://bjgpopen.org/content/bjgpoa/5/2/bjgpopen20X101140.full.pdf">20% of men</a> in their lifetime.</p> <p>Most commonly, UTIs are caused from the bug called <em>Escherichia coli</em> (E.coli). This bug lives harmlessly in our <a href="https://www.ncbi.nlm.nih.gov/books/NBK562895/">intestines</a>, but can cause infection in the <a href="http://doi.org/10.33235/anzcj.30.1.4-10">urinary tract</a>. This is why, particularly for women, it is recommended people wipe from front to back after using the toilet.</p> <p>An untreated UTI can move up to the kidneys and cause even more serious illness.</p> <p>Even when not managing infection, many people are anxious about contracting a UTI. Sexually active women, pregnant women and older women may all be at <a href="https://www.ncbi.nlm.nih.gov/books/NBK436013/">increased risk</a>.</p> <h2>Why cranberries?</h2> <p>To cause a UTI, the bacteria need to attach to the wall of the <a href="https://www.nature.com/articles/s41598-023-44916-8">urinary bladder</a>. Increasing fluids helps to flush out bacteria before it attaches (or makes its way up into the bladder).</p> <p>Some beneficial compounds in cranberry, such as <a href="https://www.cochrane.org/CD001321/RENAL_cranberries-preventing-urinary-tract-infections">proanthocyanidins</a> (also called condensed tannins), prevent the bacteria from attaching to the wall itself.</p> <p>While there are treatments, over 90% of the bugs that cause UTIs exhibit some form of <a href="https://www.who.int/news-room/fact-sheets/detail/antimicrobial-resistance">microbial resistance</a>. This suggests that they are rapidly changing and some cases of UTI might be left <a href="https://www.scientificamerican.com/article/antibiotic-resistant-utis-are-common-and-other-infections-may-soon-be-resistant-too/">untreatable</a>.</p> <h2>What we found</h2> <p>Our analysis <a href="https://www.sciencedirect.com/science/article/pii/S2405456924001226">showed</a> a 54% lower rate of UTIs from cranberry juice consumption compared to no treatment. This means that significantly fewer participants who regularly consumed cranberry juice (most commonly around 200 millilitres each day) reported having a UTI during the periods assessed in the studies we analysed.</p> <p>Cranberry juice was also linked to a 49% lower rate of antibiotic use than placebo liquid and a 59% lower rate than no treatment, based on analysis of indirect and direct effects across six studies. The use of cranberry compounds, whether in drinks or tablet form, also reduced the prevalence of symptoms associated with UTIs.</p> <p>While some studies we included presented conflicts of interest (such as receiving funding from cranberry companies), we took this “high risk of bias” into account when analysing the data.</p> <h2>So, when can cranberry juice help?</h2> <p>We found three main benefits of cranberry juice for UTIs.</p> <p><strong>1. Reduced rates of infections</strong></p> <p>Increasing fluids (for example, drinking more water) reduced the prevalence of UTIs, and taking cranberry compounds (such as tablets) was also beneficial. But the most benefits were identified from increasing fluids and taking cranberry compounds at the same time, such as with cranberry juice.</p> <p><strong>2. Reduced use of antibiotics</strong></p> <p>The data shows cranberry juice lowers the need to use antibiotics by 59%. This was identified as fewer participants in randomised cranberry juice groups required antibiotics.</p> <p>Increasing fluid intake also helped reduce antibiotic use (by 25%). But this was not as useful as increasing fluids at the same time as using cranberry compounds.</p> <p>Cranberry compounds alone (such as tablets without associated increases in fluid intake) did not affect antibiotic use.</p> <p><strong>3. Reducing symptoms</strong></p> <p>Taking cranberry compounds (in any form, liquid or tablet) reduced the symptoms of UTIs, as measured in the overall data, by more than five times.</p> <h2>Take home advice</h2> <p>While cranberry juice cannot treat a UTI, it can certainly be part of UTI management.</p> <p>If you suspect that you have a UTI, see your GP as soon as possible.<!-- Below is The Conversation's page counter tag.

But while they enrich our lives in countless ways, we often fail to consider the potential impact of screen time on our cognitive abilities.</p> <p>In a <a href="https://link.springer.com/article/10.1007/s11065-023-09612-4">new meta-analysis</a> of dozens of earlier studies, we’ve found a clear link between disordered screen use and lower cognitive functioning.</p> <p>The findings suggest we should exercise caution before advocating for more screen time, and before introducing screens into even more aspects of daily life.</p> <h2>Young people’s screen time is increasing</h2> <p>In 2020, a UNSW Gonski Institute for Education report <a href="https://www.gie.unsw.edu.au/sites/default/files/documents/UNSW%20GIE%20GUD%20Phase%201%20Technical%20Report%20MAR20%20v2.pdf">noted a concerning statistic</a>: about 84% of Australian educators believe digital technologies are distracting in a learning environment.</p> <p>And according to the ABC, a recent Beyond Blue <a href="https://www.abc.net.au/news/2023-09-18/mental-health-depression-anxiety-support-coming-for-schools/102831464">survey</a> of Australian teachers identified excessive screen time as the second-most significant challenge for young people, just behind mental health issues.</p> <p>Despite mounting concerns, more than half of Australian schools have embraced a “<a href="https://www.linewize.io/anz/blog/the-rise-of-byod-in-australian-schools">bring your own device</a>” policy. Students are spending more time online than <a href="https://read.oecd-ilibrary.org/education/students-computers-and-learning_9789264239555-en#page46">ever before</a> and starting at increasingly younger ages. A 2021 report by <a href="https://www.commonsensemedia.org/sites/default/files/research/report/8-18-census-integrated-report-final-web_0.pdf">Common Sense Media</a> estimated tweens spend an average of 5 hours and 33 minutes using screen-based entertainment each day, while teenagers devote a whopping 8 hours and 39 minutes.</p> <p>A surge in screen use has led to some individuals, including children, adolescents and adults, developing screen-related addictions. One example is gaming disorder, for which <a href="https://journals.sagepub.com/doi/full/10.1177/0004867420962851">2–3% of people</a> meet the criteria.</p> <h2>What is ‘disordered screen use’?</h2> <p>The impact of screens on our cognitive abilities – that is, our thinking skills such as attention, memory, language and problem-solving – has sparked much debate.</p> <p>On one hand, some researchers and reporters claim screen use can have negative effects, such as <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-022-12701-3">health problems</a>, shortened attention <a href="https://time.com/3858309/attention-spans-goldfish/">spans</a> and hindered <a href="https://www.researchgate.net/publication/312489265_The_relationship_between_television_exposure_and_children's_cognition_and_behaviour_A_systematic_review">development</a>.</p> <p>On the other, schools are <a href="https://www.smh.com.au/education/tech-takeover-classrooms-crowded-with-digital-devices-20200125-p53ul1.html">increasingly adopting</a> technology to boost student engagement. Tech companies are also marketing their products as tools to help you enhance your problem-solving and memory skills.</p> <p>Our <a href="https://link.springer.com/article/10.1007/s11065-023-09612-4">recent study</a> sought to understand the potential cognitive consequences of “disordered screen-related behaviours”. This is a broad category of problematic behaviours that may include screen dependency, and persisting with screen use even when it’s harmful.</p> <p>We conducted a meta-analysis of 34 studies that explored various forms of screen use (including gaming, internet browsing, smartphone use and social media use) and compared the cognitive performance of individuals with disordered screen use to those without it.</p> <p>Our findings paint a concerning picture.</p> <h2>Differences in cognitive function</h2> <p>Across these rigorously peer-reviewed studies, individuals with disordered screen use consistently demonstrated significantly poorer cognitive performance compared to others.</p> <p>The most affected cognitive domain was attention, and specifically sustained attention, which is the ability to maintain focus on an unchanging stimulus for an extended period.</p> <p>The second-most notable difference was in their “executive functioning” – particularly in impulse control, which is the ability to control one’s automatic responses.</p> <p>Interestingly, the type of screen activity didn’t make a difference in the results. The trend also wasn’t confined to children, but was observed across all age groups.</p> <h2>Two ways to interpret the results</h2> <p>Why do people with disordered screen-related behaviours have poorer cognitive functioning?</p> <p>The first explanation is that disordered screen use actually leads to poorer cognitive function, including poorer attention skills (but we’ll need more experimental and longitudinal studies to establish causality).</p> <p>If this is the case, it may be the result of being constantly bombarded by algorithms and features designed to capture our attention. By diverting our focus outward, screen use may weaken one’s intrinsic ability to concentrate over time.</p> <p>Crucially, impaired attention also <a href="https://akjournals.com/view/journals/2006/10/1/article-p77.xml">makes it harder to disengage</a> from addictive behaviours, and would therefore make it harder to recognise when screen use has become a problem.</p> <p>The second explanation is that people who already have poorer cognitive functioning (such as less inhibitory control) are more likely to engage in disordered screen use.</p> <p>This could be a result of the plethora of addictive cues designed to keep us glued to our screens. Being bombarded by these could make it harder to <a href="https://akjournals.com/view/journals/2006/9/4/article-p990.xml">pull the brakes</a> on screen use.</p> <p>Although the literature doesn’t seem to favour this explanation – and does seem to suggest that cognitive functioning is impaired as a result of disordered screen use – it’s still a possibility we can’t rule out.</p> <p>Attention is the bedrock of everyday tasks. People with weakened attention may struggle to keep up in less stimulating environments, such as a static workplace or classroom. They may find themselves turning to a screen as a result.</p> <p>Similarly, people with less inhibitory control would also find it more challenging to moderate their screen use. This could be what drives them towards problematic screen-related behaviours in the first place.</p> <h2>Who should shoulder the responsibility?</h2> <p>Research indicates people with impaired cognitive functioning usually aren’t as well equipped to moderate their own screen time.</p> <p>Many users with disordered screen use are <a href="https://www.sciencedirect.com/science/article/pii/S0747563220302326?casa_token=BQv_N_MFffYAAAAA:AsGkAfdwXjCZHJB463G40Mx-ckS2Q1c8jSOn2SWR_9iW64eWaQsru1IJAZBDCgSPXwhZ3Qwl">young</a>, with mainly males engaging in internet gaming and mainly females engaging in social media use. Neurodiverse people are <a href="https://www.mdpi.com/1660-4601/19/9/5587">also at greater risk</a>.</p> <p>Tech companies are driven by the goal of <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">capturing our attention</a>. For instance, Netflix chief executive Reed Hastings acknowledged the company’s <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">most formidable competitor was sleep</a>.</p> <p>At the same time, researchers find themselves struggling to keep up with the pace of technological innovation. A potential path forward is to encourage open-access data policies from tech companies, so researchers can delve deeper into the study of screen use and its effect on individuals. <!-- Below is The Conversation's page counter tag.

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michael-hornberger-1507154">Michael Hornberger</a>, <a href="https://theconversation.com/institutions/university-of-east-anglia-1268"><em>University of East Anglia</em></a></em></p> <p>Some people seem to be more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11003087/#:%7E:text=Some%20individuals%20are%20able%20to,into%20a%20widely%20debated%20concept.">resilient</a> to developing Alzheimer’s diseases, despite having the biological hallmarks of the devastating disease. For obvious reasons, scientists are very interested in studying this special group of people.</p> <p>Alzheimer’s disease, the most common form of dementia, is thought to start because of a build-up of two proteins in the brain: amyloid and tau. Once these proteins accumulate, for yet-to-be-determined reasons, they become toxic to brain cells (neurons) and these cells start dying. As a result, people develop symptoms such as memory loss because the brain can’t function properly with all these dead neurons.</p> <p>This cascade of events has been known for many years and is how the disease progresses in most people with Alzheimer’s. Most people, except a special group who are more resilient. But why are they resilient?</p> <p>A recent study in the journal <a href="https://actaneurocomms.biomedcentral.com/articles/10.1186/s40478-024-01760-9">Acta Neuropathologica Communications</a> investigated whether our genes might influence how resilient we are against Alzheimer’s disease symptoms when there are high levels of amyloid in our brain.</p> <p>The scientists conducted a study on the brains of three groups of people. The first group comprised people who had died with Alzheimer’s disease. The second were healthy people who died of natural causes. And the third comprised people who had high levels of Alzheimer’s proteins in the brain but never developed symptoms of the disease during their lifetime – or at least never had a diagnosis of Alzheimer’s disease.</p> <p>The last group, they considered as being resilient to Alzheimer’s disease since they had the proteins in their brains but did not have the symptoms or a diagnosis of Alzheimer’s disease during their lifetime.</p> <p>The scientists found that genes related to the activity of the immune system seem to have been more active in the Alzheimer’s resilient group. This would make sense as it is well established that the immune system helps clear the excess proteins from the brain, so genes that help this process might make us more resilient to developing symptoms of the disease.</p> <h2>How to become resilient – even if you don’t have the genes</h2> <p>This is great if you have inherited these genes from your parents, but what does it mean for the rest of us who do not have those genes? Is there a way we can make ourselves more resilient to developing Alzheimer’s disease regardless of our genes?</p> <p>“Yes” is the short answer.</p> <p>There is now good scientific evidence that <a href="https://theconversation.com/can-alzheimers-really-be-reversed-as-a-new-documentary-claims-230705">lifestyle changes</a> and drugs allow us to reduce our risk of developing Alzheimer’s disease in the future.</p> <p>In particular, physical activity has been shown to reduce our risk of developing Alzheimer’s, probably because it has a well-known beneficial effect on our immune system and hence helps clear those rogue proteins accumulating in our brains. This means that being more physically active might have the same effect on our Alzheimer’s resilience as those lucky people who have the “right” genes.</p> <p>Interestingly, we do not know how physically active the resilient people in the study were and how this might have influenced their resilience to Alzheimer’s disease.</p> <p>As so often in science, it is not clear whether nature (genes) or nurture (lifestyle) contributed to their resilience. The other interesting aspect is that the resilient people in the study died of another cause than Alzheimer’s disease, but they might have developed Alzheimer’s disease eventually if they had lived longer.<!-- Below is The Conversation's page counter tag.

Poor sleep is really bad for your health. But we found exercise can offset some of these harms

Or would this not make any difference?</p> <h2>What did we do?</h2> <p>We analysed the information provided by 380,055 middle-aged adults in the UK Biobank study, recruited between 2006 and 2010. Participants reported their level of physical activity and five aspects of their sleep.</p> <p>We grouped people based on their sleep behaviour into healthy, intermediate or poor.</p> <p>We categorised people’s level of physical activity based on <a href="https://bjsm.bmj.com/content/54/24/1451">the World Health Organization (WHO) guidelines</a>. People who met the upper bounds of the guidelines did 300 minutes of moderate intensity physical activity a week, or 150 minutes of vigorous exercise, or a combination of both. Those who met the lower bound did 150 minutes of moderate intensity exercise a week, or 75 minutes of vigorous exercise, or a combination.</p> <p>Moderate intensity physical activity usually makes you slightly out of breath if sustained for a few minutes and includes brisk walking or cycling at a leisurely pace.</p> <p>Vigorous exercise usually makes you breath hard and can include running, swimming, and playing sports like tennis, netball, soccer or footy.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=409&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=409&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=409&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=515&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=515&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/408096/original/file-20210624-15-1qfe1ay.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=515&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="caption">Doing at least 150 minutes of moderate intensity physical activity a week, or 75 minutes of vigorous exercise, can offset some of the health harms of poor sleep.</span> <span class="attribution"><a class="source" href="https://apps.who.int/iris/bitstream/handle/10665/336656/9789240015128-eng.pdf?sequence=1&amp;isAllowed=y">World Health Organization, CC BY-NC-SA 3.0 IGO</a></span></figcaption></figure> <h2>What did we find?</h2> <p>We followed up with the participants after 11 years. By May 2020, 15,503 participants had died, of which 4,095 died from heart disease and 9,064 died from cancer.</p> <p><a href="https://doi.org/10.1136/bjsports-2021-104046">We found</a> that, compared to healthy sleepers, people with poor sleep had a 23% higher risk of premature death, a 39% higher risk of dying from heart disease, and a 13% higher risk of dying from cancer.</p> <p>We then compared the data of people who slept well with those who slept poorly, and how much they exercised. We found people who had the highest risk of dying from heart disease and cancer were those who had poor sleep and didn’t meet the WHO physical activity guidelines. On the other hand, those who had poor sleep but did enough physical activity to meet the WHO guidelines didn’t have as high a risk of dying from heart disease or cancer, compared to those who slept poorly and didn’t meet the physical activity guidelines.</p> <p>For example, let’s look at the risk of dying from cancer. Those who had poor sleep and did no physical activity had a 45% higher risk of dying from cancer compared to those who had healthy sleep and exercised a lot. But among those who met the physical activity guidelines, despite poor sleep, they didn’t really have a higher risk of dying from cancer any more.</p> <p>We found physical activity levels which met at least the bottom threshold of the WHO guidelines could reduce or eliminate some of the health harms of poor sleep. So people who did at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity exercise per week were to some extent protected against the detrimental health effects of poor sleep.</p> <p>Those who had both poor sleep and did no moderate-to-vigorous intensity physical activity had the highest risks of premature death.</p> <p>Our study wasn’t designed to find out how and why physical activity may counteract some of the bad physiological impacts of poor sleep. But other research provides theories. For example, adequate physical activity may <a href="https://doi.org/10.1249/MSS.0000000000001179">reduce inflammation, help maintain a healthy glucose metabolism</a>, and <a href="https://doi.org/10.1016/j.pcad.2018.07.014">increase the number of calories burned</a>.</p> <p>It’s important to note our study was what’s called an “observational study”. It shows an association between adequate physical activity and reduced harms from poor sleep, but we must be careful in interpreting causation. It can’t conclusively say adequate physical activity <em>causes</em> the reduction of harms from poor sleep, though there’s strong evidence for an association in the right direction.</p> <p>Our study offers a hopeful message, that even if you haven’t been able to improve your sleep, you can still offset some of the health harms by doing enough exercise. <a href="https://www.sciencedirect.com/science/article/abs/pii/S009174352030339X">Our previous research</a> has also shown physical activity may help improve poor sleep patterns, which are a serious health problem across the world.</p> <p>In addition to combating some of the negative outcomes of poor sleep, physical activity can also provide many other health benefits and extend our lives. For example, a 2019 study found people who met WHO’s physical activity target above <a href="https://doi.org/10.1186/s12916-019-1339-0">lived three years longer on average</a> than those who didn’t.</p> <p>During lockdowns, access to parks, gyms, and swimming pools might be limited in many places. But there are still many ways to <a href="https://www.euro.who.int/en/health-topics/health-emergencies/coronavirus-covid-19/publications-and-technical-guidance/noncommunicable-diseases/stay-physically-active-during-self-quarantine">to stay fit and active at home during the coronavirus</a>.<!-- Below is The Conversation's page counter tag.
