Big hair? Bald? How much difference your hair really makes to keep you cool or warm

<p><a href="https://theconversation.com/profiles/theresa-larkin-952095">Th<em>eresa Larkin</em></a><em>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>We have <a href="https://theconversation.com/health-check-why-does-womens-hair-thin-out-39126">millions</a> of hair follicles on our body, including around 100,000 on our scalp.</p> <p>This might sound like a lot of hair, yet humans are described as “hairless”. We have evolved to be the only mammals with a relatively hairless body, but still with scalp hair.</p> <p>So how does your hair affect your body temperature when it’s hot or cold?</p> <p>Compared with other animals, our hair does not have as much influence on keeping us warm or cool as you might think.</p> <h2>Essential to our survival</h2> <p>Our brain function and body’s metabolism depend on an optimal temperature of around 37℃. Thermoregulation maintains this body temperature, even when we are exposed to a hotter or colder external temperature.</p> <p>For non-human mammals, body hair or fur plays a role in protecting against environmental cold or heat.</p> <p>For instance, a heavy fur coat helps keep a polar bear <a href="https://polarbearsinternational.org/polar-bears-changing-arctic/polar-bear-facts/adaptions-characteristics/">warm</a> in the cold. But fur also keeps an animal cool in the heat because it can <a href="https://www.jstor.org/stable/25064866">absorb or reflect</a> radiant heat.</p> <p>Scientists think this is why humans have kept hair on our heads. Our heads are exposed to the most heat from the sun, and scalp hair keeps our heads cool.</p> <p>Research published just last week <a href="https://www.pnas.org/doi/10.1073/pnas.2301760120">suggests</a> curly hair provides the best heat protection. That’s because curly hair’s thicker layer of insulation reduces the amount of sun that reaches the scalp.</p> <h2>But hair is not the only factor</h2> <p>When humans moved from living in the jungle to the savannah, they needed to walk and run long distances in the sun. This meant they needed a way to handle the increased body temperature that comes with physical activity in the heat.</p> <p>Sweating is the best way to lose heat and cool down, but the presence of hair reduces sweating and heat loss from the skin.</p> <p>So humans evolved to <a href="https://www.pnas.org/doi/10.1073/pnas.1113915108">lose body hair</a> to be better adapted to exercising in the heat. Fewer hair follicles in our skin made room for more sweat glands. This made our skin optimal for sweat evaporation – and the <a href="https://theconversation.com/want-to-keep-cool-on-hot-summer-days-heres-how-34489">heat loss</a> that goes with it – to keep us cool.</p> <h2>So what’s best in the heat?</h2> <p>You might think removing body hair or having a bald head is best for sweating and keeping cool when exercising in the heat. However, it’s not that simple.</p> <p>Removing head hair would increase the <a href="https://www.pnas.org/doi/10.1073/pnas.2301760120">amount of sun</a> that reaches your scalp. This means you would need to <a href="https://pubmed.ncbi.nlm.nih.gov/20683812/">sweat more</a> during exercise in the sun to reduce an increase in body temperature, but not by much.</p> <p>In fact, it’s the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4667044/#:%7E:text=The%20body%20hair%20is%20advantageous,heat%20removal%20during%20heat%20stress.">least hairy</a> areas of our body that have the highest sweat rates during exercise. These are our forehead, neck, feet and hands.</p> <p>So the best way to keep cool in the heat is to keep these areas uncovered (but still use sunscreen). Removing body hair will not have a large impact on your overall sweat rate.</p> <h2>How about when it’s cold?</h2> <p>Our body hair and head hair theoretically have a role in keeping us warm, but the effects are minimal.</p> <p>When we are cold, the muscles of the hair follicles on the body contract to cause the hairs to stand straight. This is an attempt to trap heat close to the body and we see this as goosebumps. However, because our body hair is so thin, this does not have a big effect in keeping us warm.</p> <p>Our head hair can prevent some heat loss from the head, but again this is limited.</p> <p>When it’s cold, heat can still be lost through the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4667044/#:%7E:text=The%20body%20hair%20is%20advantageous,heat%20removal%20during%20heat%20stress.">skin of the head</a> regardless of your hairstyle.</p> <p>The scalp also has only a very thin layer of fat compared to the rest of our skin, so our head has less insulation to protect against the cold.</p> <p>A warm hat or beanie is the only way to prevent too much heat lost from the head.</p> <h2>In a nutshell</h2> <p>Our head and body hair, or lack of it, does have a small role in how you maintain your body temperature.</p> <p>But overall, your hairstyle does not influence whether you feel warm or cool.<!-- Below is The Conversation's page counter tag.

How to keep your pets cool in the heat

<p>Now that the weather is warm, extra precautions in the sun are necessary not just for yourself, but for your furry companion. Try these useful tips to help keep Fido and Fluffy safe and cool in the heat all summer long.</p> <p><strong>Give them a trim –</strong> If your pet has long hair, consider grooming them seasonally, as shorter hair makes a big difference in their overall temperature.</p> <p><strong>Keep water handy –</strong> If you leave the house with your pet, always be sure to have water on you as well as a receptacle from which they can drink to keep your pet cool and hydrated. You can even set up a kiddy pool in your backyard for your dog to play in.</p> <p><strong>Look for shade –</strong> If you’re out with your dog midday, try to avoid direct sunlight by locating a shady area for a rest.</p> <p><strong>Follow their lead –</strong> If you dog or cat seems most content to stay indoors and enjoy the air conditioning, let them. They can tell if it’s too hot outside for them.</p> <p><strong>Time it right –</strong> Avoid going out midday when possible, and take your dog for walks during the mornings and evenings instead.</p> <p><strong>Never leave them in the car –</strong> Many animals die every year because irresponsible owners leave them in a car, leading to over-heating. Even if the day seems moderate in temperature, a car can still heat up drastically due to solar heat beaming in through the windows. If you’ll be leaving your car alone, leave your pet at home.</p> <p><strong>Act according to breed –</strong> If your pet has a flat-shaped face, such as a pug or Persian cat, they are especially susceptible to the heat as they are unable to cool down through panting as effectively as other breeds can. If in doubt, bring them inside where it is cooler.</p> <p><em>Image credit: Shutterstock</em></p>

Is Eurovision finally cool? That depends on your definition – ‘cool theory’ expert explain

<p><em><a href="https://theconversation.com/profiles/vanessa-brown-142590">Vanessa Brown</a>, <a href="https://theconversation.com/institutions/nottingham-trent-university-1338"><em>Nottingham Trent University</em></a></em></p> <p>With an aesthetic dependent on novelty and spectacle, and a structure that’s both disjointed and drawn-out, Eurovision – for some – cannot fail to fail. In its “failed seriousness” (the phrase writer Susan Sontag <a href="https://www.artandobject.com/news/what-camp-met-tries-define-ineffable">used to describe “camp”</a>), the song contest has all the exaggerated expressiveness that audiences associate with kitsch. So, how could it possibly be cool?</p> <p>I’m interested in viewing the show through the lens of <a href="https://irep.ntu.ac.uk/id/eprint/45239/1/1507168_Brown.pdf">cool theory</a> (which identifies different kinds of cool and breaks those down into core qualities). “Coolness” itself is a <a href="https://www.tandfonline.com/doi/full/10.1080/14797585.2021.2000837">slippery and controversial term</a> that can mean almost opposing things.</p> <p>For some, “cool” is simply what is fashionable. It can also be a rebellion against what is fashionable. Or an anti-social attitude in which nothing and no one else matters beyond your own stylish persona.</p> <p>Indeed Sam Ryder – the UK’s near-win Eurovision act of 2022 whose high energy performance combined epic, earnest vocals with flowing natural locks, pearly teeth and a bejewelled one-piece – told the Guardian in 2022 that cool is “<a href="https://www.theguardian.com/tv-and-radio/2022/may/19/cool-is-the-enemy-eurovision-hero-sam-ryder-on-how-he-ditched-his-ego-and-found-his-joy">the enemy</a>”.</p> <p>The profile of Ryder claimed he had no interest in the “detached rock star” exterior. This refers to the sense of unwillingness of “cool” musicians to have their dignity compromised by other people’s rules – an unwillingness to be caught making an effort.</p> <p>But Eurovision is all about effort. A publicised drama of rehearsals and heats, nervous waving and nail biting in the green room – the performers are just generally far too eager. Because whether it’s death metal or pared back electronica, being liked is what these musicians are here for.</p> <figure><iframe src="https://www.youtube.com/embed/RZ0hqX_92zI?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Sam Ryder’s 2022 Eurovision performance.</span></figcaption></figure> <p>On the other hand, it’s hard to imagine the uber-cool 1960s <a href="https://www.loudersound.com/features/krautrock-communism-and-chaos-the-anarchic-story-of-can">krautrock band Can</a> giving two hoots what a jury in Brussels would make of their genre-defining understated rock. Nor the jazz men Miles Davis, Charlie Parker or Lester Young, who set the parameters of cool performance with their sharp, formal attire and <a href="https://www.bloomsbury.com/uk/cool-shades-9780857854643/">refusal to acknowledge the audience</a>.</p> <h2>What kind of ‘cool’ is Eurovision?</h2> <p>Although the performers of Eurovision aren’t detached, the audience can be. Sociologist Janna Michael’s <a href="https://journals.sagepub.com/doi/abs/10.1177/1469540513493206?journalCode=joca">2015 study</a> of European urban hipsters revealed that the point of cool is not what is liked, so much as how it is liked. This goes some way to explaining Eurovision’s appeal.</p> <p>Since the 1980s, Eurovision has been presented (certainly in Britain) as something to enjoy in a specifically detached way, through irony. From 1973 to 2008, former commentator Terry Wogan’s flippant narration allowed the audience to collude in a knowing superiority over the event, finding its failed seriousness funny.</p> <p>The cult following of Eurovision among those with a camp sensibility was further endorsed by the appointment of comedian Graham Norton as Wogan’s more obviously camp successor.</p> <p>Do these fans love Eurovision because they enjoy the catharsis of the unabashed release of “bad taste”? Or because they enjoy feeling superior to those people (and nations) who genuinely engage with the drama of the competition? This is a side of <a href="https://www.abebooks.co.uk/9780719066153/Kitsch-Cultural-Politics-Taste-Ruth-0719066158/plp">cool’s ironic detachment that celebrates disdain for others</a>.</p> <p>However, many British fans now speak enthusiastically about the tolerance and openness of Eurovision. As <a href="https://www.liverpoolecho.co.uk/news/showbiz-news/eurovisions-rylan-clark-blown-away-26873868">host Rylan Clark said this year</a>: “Everyone is welcome.” In recent years Eurovision has become more obviously and consciously open to gender diversity and aligned to LGBTQ+ tastes.</p> <p>This was crystallised by bearded Austrian drag queen Conchita’s winning performance in 2014. The <a href="https://metro.co.uk/2023/05/11/eurovision-alesha-dixon-and-hannah-waddingham-turned-into-drag-queens-18770837/">drag makeovers given to all three semi-final hosts this year</a> confirmed the contest’s status as a space which endorses self-creation, individuality and tolerance – all aspects of the cool attitude.</p> <h2>Becoming mainstream</h2> <p>In the past, scholars of the theory of coolness have often focused too heavily on men and masculine, emotionally blank forms of “cool”, with composure and self-possession at their heart. Though this brand of cool is eloquently expressed in jazz, it is also visible in the consummate performer of drag.</p> <p>Thanks to the popularity of shows such as RuPaul’s Drag Race, drag – once enjoyed purely in LGBTQ+ subcultures – is now mainstream entertainment. This is perhaps one reason Eurovision has suddenly become perceived as “cool” <a href="https://www.sciencedaily.com/releases/2012/06/120607180110.htm">by some</a>. But experiences of exclusion and marginalisation have historically been the conditions in which modern cool has been forged.</p> <p>The very fact that Eurovision has been viewed for decades as a cultural white elephant, a place of almost inconsequential melodrama, gives it the potential to be resurrected as cool.</p> <p>Liking Eurovision was once an anti-mainstream position. This gave the show the potential to become “cool”, through both its exaggeration of qualities seen as undesirable by dominant social tastes, and its willingness to push the boundaries of convention, despite the detractors.</p> <p>The concept of cool is complicated – and it is changing. Indeed, <a href="https://www.sciencedaily.com/releases/2012/06/120607180110.htm">some recent studies</a> have shown that perception of coolness is connected to activism and pro-social traits. Eurovision may seem like sparkly fluff, but perhaps now more than ever, it is also a vehicle for promoting greater acceptance of other ways of life. It’s all cool.<!-- Below is The Conversation's page counter tag.

Jacinda Ardern’s cool response to car chase by anti-vaxxers

<p dir="ltr">Jacinda Ardern, Prime Minister of New Zealand, appeared unbothered by a car chase she was involved in that saw anti-vaxxers pursuing the van she was in, forcing it onto a kerb.</p> <p dir="ltr">Footage of the chase has recently gone viral online, showing a group of anti-vaccination activists use their own vehicles to attempt to block Ardern in the Bay of Islands.</p> <p dir="ltr">The group can be heard shouting abuse at Ardern’s vehicle as officers with the Diplomatic Protection Service stood guard. One shouted, “Shame on you!” while another shouted, “We do not consent”. Another protestor claimed Ardern was “hiding in the van”, calling her a “wussy” and a “Nazi”.</p> <p dir="ltr">The video also shows the vehicle attempting to pull on to the main road, taking to the footpath to avoid a car attempting to block it in. A woman in one of the cars pursuing it can be heard saying, “Oh this is fun! We‘re on a chase”, while a man says that the group just wanted “a few words” with Ardern. They joked, “We’re in pursuit for the Prime Minister”.</p> <p dir="ltr">Ardern described it as “just another day”, telling reporters, “at no point was I worried about my safety or the safety of anyone that was with me.” She added, “Every day is faced with new and different experiences in this job … We are in an environment at the moment that does have an intensity to it that is unusual for New Zealand. I do also believe that with time it will pass.”</p> <p dir="ltr">She said, “I see that as just being a reflection of the fact that we are the decision makers. And if people don’t like the decisions that are being made, then it’s us that of course will hear the feedback about that.”</p> <p dir="ltr">The chase comes amid a small but notable rise in threats towards public officials involved in New Zealand’s pandemic response, according to police data released to<span> </span><em>1News<span> </span></em>this week. Threats to politicians reached a three-year high in one month last year. Most of the reports, which at times spiked to as many as 16 per month, involved threats aimed at Prime Minister Ardern.</p> <p dir="ltr">Lance Burdett, who protected former Prime Minister Helen Clark, said COVID-19 vaccinations had become a sticking point with a small minority. While close to 95% of adults in New Zealand are now fully vaccinated, some have strongly resisted getting the jab or the mandates that have come with the country’s pandemic response.</p> <p dir="ltr"><em>Image: Mark Mitchell-Pool/Getty Images</em></p>

How to cope with extreme heat days without racking up the aircon bill

<p>Summer in Australia is <a href="http://www.bom.gov.au/climate/updates/articles/a032.shtml">getting hotter</a>. Extreme heat events, with daytime temperatures over 35 degrees Celsius, are becoming more common and we are getting more of these days in a row.</p> <p>We all need to prepare ourselves, our homes and our neighbourhoods for hot and very hot days. Since 2016, the <a href="https://www.westernsydney.edu.au/__data/assets/pdf_file/0020/1161470/cooling-the-commons-report.pdf">Cooling the Commons</a> research project has been working with people living in some of Sydney’s hottest neighbourhoods to learn how they cope with heat.</p> <p>Discussion groups with residents across hotspots in Western Sydney, including Penrith, Cranebrook and St Marys, highlighted a wealth of things we can do to manage heat. We published some of the following tips in a recent <a href="https://www.westernsydney.edu.au/ics/news/new_resource_by_institute_researchers_provides_advice_on_how_to_prepare_for_heat">flier</a>.</p> <p><strong>Why can’t we all just rely on air conditioning?</strong></p> <p>Official advice for extreme heat is often to stay inside and turn on the air conditioning. While air conditioning can play a role, <a href="https://www.canstarblue.com.au/appliances/air-conditioning-running-costs/">not everyone can afford it</a>. Low-income and older households can be especially vulnerable to bill shock and are more likely to feel the impacts of extreme heat.</p> <p>There is also the risk that running air conditioners uses <a href="https://www.theguardian.com/australia-news/2019/jul/09/australias-emissions-reach-the-highest-on-record-driven-by-electricity-sector">energy resources that contribute further to global warming</a>. More immediately, hot exhaust air from air-conditioning units can <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2013JD021225">make the local environment hotter</a>. This means keeping one home cool can make it harder for neighbours to keep their homes cool and make being outside even more uncomfortable.</p> <p>Air conditioning in private homes creates a cool refuge for only some. Unless those homes have an open-door policy on hot days, many of us will need to find other ways to keep cool. If you do have air conditioning, think about how you could share your air with those near you who might really need it.</p> <p><strong>Prepare before the heat hits</strong></p> <p><strong><em>Shade is important for creating more comfortable living spaces.</em></strong></p> <p>Identify which parts of your home get the most afternoon sun in summer. Can you plant trees or vines, or move a pot plant outside the window to create a green screen? Can you attach awnings to shade the windows?</p> <p>Low-cost temporary solutions can include attaching light-coloured shade cloth outside the window using removable hooks, or installing heavy drapes or blinds inside. Blankets or even aluminium foil are a low-cost creative way of keeping heat out.</p> <p><strong><em>Open up to let in cool air at night</em></strong></p> <p>Can you open the windows and doors overnight to let in cooler air? If you are concerned about security, look for options for locking the windows in an open position, or using flyscreens and security grilles on windows and doors.</p> <p>A low-cost option to keeping flying insects at bay on hot nights is a mosquito net over the window or around the bed.</p> <p><strong><em>Use low-cost resources to prepare in advance.</em></strong></p> <p>Ceiling or portable fans are one of the best ways to cool your body when it’s hot. But remember fans don’t cool rooms, so turn off the fan when you leave the room or you’re just burning electricity.</p> <p>Find ice trays and containers to freeze water – cake tins and storage containers are a good option. Putting these in front of a portable fan will mean the fan blows cool air.</p> <p>Putting a wet face cloth on the insides of your wrists, around your ankles or on the back of your neck will bring down your body temperature. Hanging damp sheets in doorways or in front of a fan will help keep the temperature down – although the trick with the sheets won’t work if it’s a really humid day.</p> <p><strong>How to stay cool and comfortable on hot days</strong></p> <p>Morning is likely to be the coolest time of the day. Open up your windows and doors to let in the cooler morning air.</p> <p>It’s the best time to be active – walk the dog, take the kids to the park, go for a swim. If possible, do your cleaning, cooking or outside work now. Plan meals that don’t require an oven.</p> <p><strong><em>Close up as it heats up.</em></strong></p> <p>As the day starts to get hot, close the house up – shut windows, blinds and curtains. This could be as early as 9am on really hot days. If you are heading out to work, do this before you leave home.</p> <p>Closing internal doors can help to keep the heat in one part of your home. You need to close doors to any parts of the home that get hot before the day gets hot.</p> <p><strong><em>Stay hydrated.</em></strong></p> <p>Drink plenty of water throughout the day. Put a jug of tap water in the fridge and remember to top it up.</p> <p>Don’t forget to move pet water bowls and day beds out of the sun. If you live in a dry area, it can’t hurt to put out extra water bowls for needy wildlife!</p> <p><strong><em>Find a cooling refuge.</em></strong></p> <p>If your home gets uncomfortably hot, find the closest cooling refuges in your neighbourhood. These are places where you can go to cool down. Good examples that won’t break the bank are the local swimming pool or library.</p> <p>Some local councils provide <a href="http://coolparramatta.com.au/">lists</a> of <a href="https://www.penrithcity.nsw.gov.au/waste-environment/cooling-the-city/beat-the-heat">cooling centres</a> on their websites.</p> <p><strong><em>Save air conditioning for when it’s most needed.</em></strong></p> <p>Try to save air conditioning for the hottest parts of the day. It will be most effective and cheapest to run if your home is well insulated and you’ve closed it up for the day.</p> <p><strong><em>Look after neighbours.</em></strong></p> <p>Remember to check on elderly or frail neighbours. Along with the very young, they are usually more affected by the heat and may need to cool down sooner than you do.</p> <p>If your neighbours are in need, consider inviting them into your home to cool down. When it’s hot, let’s <a href="https://www.semanticscholar.org/paper/Infrastructures-of-Care%3A-Opening-up-%E2%80%9CHome%E2%80%9D-as-in-a-Lopes-Healy/1920004e258483d40017ff468370e4892e11fce5">think of our cities as social commons</a> rather than a collection of private spaces.</p> <p><span><a href="https://theconversation.com/profiles/emma-power-250930"><em>Emma Power</em></a><em>, Senior Research Fellow, Geography and Urban Studies, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>; <a href="https://theconversation.com/profiles/abby-mellick-lopes-388977">Abby Mellick Lopes</a>, Associate Professor, Design, School of Humanities and Communication Arts, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>, and <a href="https://theconversation.com/profiles/louise-crabtree-128457">Louise Crabtree</a>, Associate Professor, Institute for Culture and Society, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></span></p> <p><em>This article is republished from <a href="http://theconversation.com">The Conversation</a> under a Creative Commons license.

5 extraordinary uses for paper bags

<p><span style="font-weight: 400;">Paper bags are very to handy to have around the home. While they are standardly use to carry food, they have other incredible uses.</span></p> <p><span style="font-weight: 400;">Here are five extraordinary ways you can use paper bags.</span></p> <p><strong>1. Dry herbs</strong></p> <ul> <li><span style="font-weight: 400;">Wash and thoroughly dry several bunches of herbs and place them upside down in a paper bag.</span></li> <li style="font-weight: 400;"><span style="font-weight: 400;">Tie the bag at the stems, punch in a few holes and put it in a warm, dry place for two weeks.</span></li> <li style="font-weight: 400;"><span style="font-weight: 400;">Grind the herbs, then store. </span></li> </ul> <p><strong>2. Boost compost</strong></p> <ul> <li style="font-weight: 400;"><span style="font-weight: 400;">A great addition to any compost heap, brown paper bags contain less ink and pigment than newspaper, and attract more worms.</span></li> <li style="font-weight: 400;"><span style="font-weight: 400;">First shred and wet the bags, then mix into the compost well so they don’t dry out and blow away.</span></li> </ul> <p><strong>3. Prepare vegetables</strong></p> <ul> <li style="font-weight: 400;"><span style="font-weight: 400;">Rip open one or two paper bags and spread them over your benchtop when peeling vegetables, shelling peas, or doing any other messy job.</span></li> <li style="font-weight: 400;"><span style="font-weight: 400;">When you’re done, simply fold the paper and throw it all into the compost.</span></li> </ul> <p><strong>4. Catch dust</strong></p> <ul> <li style="font-weight: 400;"><span style="font-weight: 400;">Remove dust from a mop by placing a paper bag over the head, then use string or a rubber band to stop it slipping.</span></li> <li style="font-weight: 400;"><span style="font-weight: 400;">Shake and gently bump the mop so the dust falls into the bag, let the dust settle, then take off the bag.</span></li> </ul> <p><strong>5. Spray stuff</strong></p> <ul> <li style="font-weight: 400;"><span style="font-weight: 400;">You don’t have to make a mess when spray-painting small items.</span></li> <li style="font-weight: 400;"><span style="font-weight: 400;">Just place what you’re painting inside a large paper bag and it will contain the excess spray.</span></li> <li style="font-weight: 400;"><span style="font-weight: 400;">Once the item has dried, remove it and throw the bag away.</span></li> </ul> <p><em><span style="font-weight: 400;">Republished with permission of</span><a href="https://www.handyman.net.au/5-extraordinary-uses-paper-bags?slide=all"><span style="font-weight: 400;"> Handyman.net.au.</span></a></em></p>

It's never too late: How I ran away with the circus

<p>As a kid in the bush, John Smyth didn’t have much chance to see the circus in person, but he had a treasured picture book about life under the Big Top. More than 60 years later, Smyth got to become part of the Stardust Circus world, not as a tumbler or lion tamer – but as a teacher.</p> <p>Back in 1999, the career high-school teacher decided it was time to retire and, together with his wife Helen, embark on an epic journey around Australia. They covered 33,000km in six months. When they returned, Smyth found he missed the classroom, so came out of retirement to spend ­another eight years doing casual teaching – but, eventually, his wanderlust returned and he and Helen headed back on the road.</p> <p>Today, the 75-year-old physics and mathematics teacher slots in time with his grandkids around a packed diary as a volunteer teacher to school students who live in remote locations, under a scheme known as Volunteers for Isolated Students’ Education (VISE).</p> <p><img style="width: 0px; height: 0px;" src="https://oversixtydev.blob.core.windows.net/media/7825484/rd.jpg" alt="" data-udi="umb://media/0460e53155b2483aab144be28e5bdb45" /></p> <p>VISE pairs up energetic people with educational experience – usually retired teachers, such as John – with children whose schooling is largely done remotely, because they live too far away from towns and cities to attend regular school. With their classes conducted via satellite hook-ups, Skype or whatever other methods are available, the children have virtual contact with a paid teacher for several hours a day. The rest of the time they are given assignments to complete. VISE volunteers go and stay with these remote families for six weeks at a time to provide encouragement and practical help to the students.</p> <p>John grew up in the country and was immediately intrigued when he heard about the scheme. Helen was just as keen. “We love the bush,” he says. While the teacher’s partner isn’t required to contribute, they often help around the home, in the garden or around the property. Since volunteers typically stay for the full six weeks, it’s important for couples to agree on the locations they apply for.</p> <p>“We’d decided we wouldn’t take a placement where we lived in the house with the family,” John says. “We opted for ones where we could take our own caravan or we’d have a ‘donga’ hut or a cottage, so that we had somewhere we could get away.”</p> <p>After eight VISE postings, and encountering some challenging families and students, John is still keen to do more. “Occasionally I have had to take a stand and say, ‘If you want my help, here I am, otherwise I’ll pack up and go home – I’m too busy to be sitting around here if we’re not going to work.’ But it’s always turned out really well.” He remains in fond contact with a number of his former students.</p> <p>He’s racked up stints in some of Australia’s most remote locations, including a 38,000-ha sheep property where they had to meet the mail plane to get school materials, and an 80,000-ha National Park that was 500km from the nearest supermarket. Then John nabbed one of the most sought-after placements in the scheme: a travelling post with Stardust Circus. “It was just wonderful,” he says of the weeks he and Helen spent on the road last year, working with the children in a specially equipped mobile schoolroom.</p> <p>The lesson timetable was built around the kids’ performance schedules. “The eight-year-old I tutored was a fabulous gymnast who was part of the teeterboard act,” he explains. “A big bloke would jump on the other side, he would swing up in the air, do a couple of twirls and land on his uncle’s shoulders ... and his uncle was standing on the boy’s father’s shoulders!”</p> <p>The circus still includes some animal acts, including lions, monkeys, horses, goats and pigs. John and Helen found it extraordinary enough to drift off to sleep to the sound of lions roaring, but then one day the lion-tamer, Matt, accorded them a very special privilege, inviting them in to meet four 13-month-old cubs in person.</p> <p>While it was understandably a little scary at first going into their enclosure, John says it was “an absolutely fantastic, never to be forgotten experience” which just goes to show it really is never too late: “In my 75th year I finally got to realise my boyhood dream of running away with the circus!”</p> <p><strong>IF YOU'RE TEMPTED</strong></p> <p>National Seniors Australia chief executive Michael O’Neill says John’s approach is increasingly common. “We’re seeing more and more people moving from full-time work into other areas of activity that are not traditionally associated with retirement or the later years of life.”</p> <p>In fact, he says, ‘retirement’ is “almost a dirty word now. People want to enter into new experiences, using previous life knowledge, rather than sitting back and ‘retiring’ as we came to know it in previous generations.”</p> <p>As in John’s case, many are keen to continue giving back to society, but O’Neill says the way we do this has also changed.</p> <p>“Many will now say, ‘I’m happy to volunteer and give my time for this particular cause, but let me be clear: I want to contribute my knowledge and skills to your organisation. Don’t think I’m going to be down the back making cups of tea.’?”</p> <p><em>Written by Hazel Flynn.

Health check: Do cold showers cool you down?

<p>It’s normal to feel hot, sweaty and uncomfortable in warm weather, but what’s the best way to cool down? To answer this question, we first need to look at how the body maintains stable internal (core) temperature.</p> <p>We feel uncomfortable at hot environmental (ambient) temperatures because our bodies are striving to maintain a constant core temperature. When the ambient temperature is too high, we engage in reflexive (things our nervous system does without us realising) and behavioural (things we do) adaptations to try to cool ourselves. The discomfort we feel is the motivation for the behavioural adjustments. Many of us just want to jump in a cold shower. So will this help to cool us down?</p> <p>From the physiological perspective, core temperature is what our body is regulating. Small changes in core temperature can quickly lead to illness (such as heat exhaustion, fever and heat stroke). We are not consciously aware of our core body temperature. Although the body has sensors that monitor core body temperature, our perception of temperature comes exclusively from skin temperature sensors (temperature receptors). These allow us to sense if we are cold, comfortable or hot.</p> <p>Human biology is remarkable; we maintain a relatively stable core body temperature over a wide range of ambient temperatures. For instance, core body temperature only differs by 0.5⁰C over a wide ambient temperature range (as wide as <a href="http://link.springer.com/article/10.1007%2Fs00484-013-0673-8">12-48⁰C</a>). The body’s ability to restrict core temperature to such a tight range means reflexes to control core temperature need to occur before there is an actual change in core temperature.</p> <p>Controlling blood flow to the skin is an important way of controlling internal body temperature. The circulatory system moves blood around the body; it also transports heat around the body, so changing where the blood flows allows the body to determine where the heat goes. With reduced blood flow to the skin, heat is conserved in the body, and with increased blood flow to skin, heat is lost to the environment.</p> <p>In cold environments, there is almost no blood flow to the skin to keep all the heat in (which is why we get frostbite). This is why, when we’re very cold, our skin is pallid and pale. At hot ambient temperatures, skin blood flow can increase to as much as seven litres per minute to try to expel all the heat through the skin. This is <a href="http://www.nejm.org/doi/full/10.1056/NEJMra011089">a 23-fold increase</a> to normal, and about 35% of the total volume of blood volume pumped from the heart. This is why, when we’re hot, we can appear flushed.</p> <p>The exquisite control of blood flow to the skin means there is an optimum ambient temperature (known as thermoneutral), where the body does not engage in any regulatory activity to maintain core temperature. This occurs when the skin blood flow is <a href="http://www.sciencedirect.com/science/article/pii/S1566070216300029">about 300mL a minute</a>.</p> <p>Other mechanisms for temperature control are quite different. In cold environments, the body increases heat generation to <a href="http://www.sciencedirect.com/science/article/pii/S1566070216300157">maintain core temperature</a>. One method is to move the muscles to heat them up (shivering thermogenesis); another is to speed up metabolism to produce more heat (non-shivering thermogenesis).</p> <p>In hot environments, when air temperature is higher than skin temperature (above roughly 33⁰C), heat loss only takes place with sweating. When sweat evaporates off our skin, it <a href="http://physics.stackexchange.com/questions/255016/evaporation-of-water">has a cooling effect</a>. Sweating, or wet skin, can increase the amount of heat lost from the body by as much as <a href="http://www.sciencedirect.com/science/article/pii/0013935167900023">ten times</a>.</p> <p>Given free range, animals will spend most of their time in a <a href="http://jap.physiology.org/content/92/6/2667">thermoneutral environment</a>, where they are most comfortable (the comfort zone). Humans are most comfortable (thermoneutral) <a href="http://www.sciencedirect.com/science/article/pii/0013935167900023">at an ambient temperature of about 28⁰C</a> (and a skin temperature of 29-33⁰C). The further we are away from that temperature (either cold or warm), the more uncomfortable we feel.</p> <p><strong>The verdict</strong></p> <p>Our bodies respond more to changes in skin temperature <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2290547/">than core temperature</a>. So, if we cool part of the body (for instance with a cold sponge, or cold shower), skin blood flow decreases and <a href="https://www.jstage.jst.go.jp/article/physiolsci/57/4/57_4_241/_article">skin temperature falls</a>.</p> <p>Here we “feel” cooler because cold water causes cold temperature receptor activation in the skin. We may also feel more comfortable, as our skin temperature enters the comfort zone. But because there is less blood flowing to the skin, we’ll actually keep more heat inside, thus leading to an unintended overall increase in core temperature.</p> <p>A cold shower to “cool off” might seem a good immediate choice. We feel cooler because of the combination of the cold water and the decreased blood flow to the skin, but in fact our core will get warmer because of reduced heat loss from the body without skin blood flow. Some minutes later, we feel hot again. But a warm sensation on the skin will lead to increased blood flow to the skin, increasing heat loss from the body.</p> <p>So, keeping cool in summer will be more effective with a warm shower (water temperature about 33⁰C) rather than a cold shower (water temperature 20-25⁰C). It will seem warm initially but after a few minutes will provide better comfort in the long term.</p> <p><em>Written by Yossi Rathner, Joshua Luke Ameliorate and Mark Schier.

“This is so cool”: Serena Williams faces Roger Federer for first time

<p>Roger Federer took the lead in the highly anticipated match against Serena Williams.</p> <p>Federer awarded Switzerland a 1-0 lead with a 6-4 6-1 win over Frances Tiafoe.</p> <p>After a shaky start, Williams managed to post a 4-6 6-4 6-3 win over Belinda Bencic.</p> <p>But with Federer and Williams being the biggest names in tennis, the match was one that fans were looking forward to since it was announced.</p> <p>The fact that the score was tied also added to the anticipation.</p> <p>After losing to Greece in their opening tie, the US needed to beat Switzerland in order to remain in the running for the title. But unfortunately for them, it was Switzerland who came out on top.</p> <p>“I was so excited, and literally it was the match of my career,” said Williams about the match against Federer.</p> <p>“Just playing someone so great, and someone you admire so much, and a match that actually means something – it’s not often that happens.</p> <p>“It was really cool to play someone still in their prime, like me, both in our primes. I’m kind of sad it’s over.”</p> <p>To celebrate the monumental match, the two players took a selfie together after Federer’s win.</p> <p>“I was nervous returning (her serve) because you just don’t know,” Federer said when asked about Williams.</p> <p>“People talk about her serve so much and I see why – it is such a wonderful serve because you just can’t read it, you don’t see it until the very end.</p> <p>“It was great great fun. She is a great champion and you see how focused and determined she is and I love that about her.”</p> <p>With Switzerland winning both their ties, they have earned their spot in the final with victory over Greece on Thursday night.</p>

<p>The Duke of Cambridge, Prince William, who celebrated his 36<sup>th</sup> birthday on June 21, has shared the sweetest new anecdotes about his two eldest children, Prince George and Princess Charlotte.</p> <p>Attending the official handover of the newly built Defence and National Rehabilitation Centre (DNRC) in Nottinghamshire in the UK on his birthday, the proud dad explained that four-year-old George thinks he has a cool dad, after seeing him at work on the building site.</p> <p>He joked that his “street cred” skyrocketed after his first-born son saw his dad behind the wheel of a digger during construction of the rebab centre in 2017.</p> <p><img width="399" height="557" src="https://oversixtydev.blob.core.windows.net/media/7819336/screen-shot-2018-06-22-at-44024-pm.png" alt="Screen Shot 2018-06-22 At 4.40.24 Pm"/></p> <p>“George was very envious as I got to drive a digger… When completed next year, the DNRC will be a world leading centre for rehabilitation. It will provide pioneering treatments,” Prince William said during his official speech about the new centre, which he will be patron of, and will provide rehabilitation facilities for members of the Armed Forces who have suffered injury or trauma during their service.</p> <p>Although it was William’s birthday on the day of the event, and royals have permission to be excused from attending official engagements on their special day, the kind-hearted prince broke with tradition to attend the unveiling.</p> <p>Prince Harry has previously revealed that his nephew has a soft spot for anything with wheels.</p> <p>“I can always hear the wheels of those plastic tractors that George loves playing,” Harry said.</p> <p><img width="444" height="556" src="https://oversixtydev.blob.core.windows.net/media/7819338/screen-shot-2018-06-22-at-44157-pm.png" alt="Screen Shot 2018-06-22 At 4.41.57 Pm (1)"/></p> <p>When it comes to 3-year-old Charlotte, Prince William revealed that she is taking after her stylish mother and is obsessed with fashion.</p> <p>Attending another event on Tuesday earlier in the week in Liverpool, the Duke was gifted a pink satchel for his daughter, which was embossed with her name – with the design of the bag aptly dubbed ‘Mini-Windsor’.</p> <p>Thanking the makers of the bag, Keith and Gail Hanshaw of Liverpool Echo, Prince William gushed, “Charlotte will be obsessed with that – I’ll never be able to get it off her.”</p>

How to stay cool and save energy this summer

<p>Keep cool this summer and save energy costs by following these simple tips around the house.</p> <p>1. You don’t have to forgo air-conditioning completely to save on energy bills. Setting your air-con one degree warmer than you normally world can cut costs by 10 per cent. The optimal temperature is between 24 and 25 degrees.</p> <p>2. Drapes and roller blinds that cover the entire window can reduce heat exchange by almost half. For sun-facing windows, choose light-coloured backings for blinds as they deflect sun heat.</p> <p>3. Before the heat sets in on a hot day, close windows, draw blinds and close off rooms that are not in use. This will help reduce heating inside.</p> <p>4. Consider planting trees, wall vines and thick shrubs to provide shade to the house – not just for the windows but walls and roofs as well. A shaded house can cool the home by up to 12 degrees.</p> <p>5. If planting is not an option, add exterior shades or awnings. This can decrease temperature inside the home by up to three degrees.</p> <p>6. Open windows or doors on both sides of the home to allow the breeze to flow through. Do this at night if the day is particularly humid and hot.</p> <p>7. Better insulate your house’s walls and ceilings. Good insulation means cool air is more likely to stay in the house.</p> <p>8. Skip using the dryer, which will heat up the house, to hang dry clothes.</p> <p>9. Use a fan instead of the aircon where possible. It goes without saying that it’s a much cheaper than an air-conditioning system.</p> <p>10. Cook outdoors on the BBQ. The indoor stove or oven can raise kitchen temperatures by up to 10 degrees.</p>
