Yes, blue light from your phone can harm your skin. A dermatologist explains

<p><em><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Social media is full of claims that everyday habits can harm your skin. It’s also full of recommendations or advertisements for products that can protect you.</p> <p>Now social media has blue light from our devices in its sights.</p> <p>So can scrolling on our phones really damage your skin? And will applying creams or lotions help?</p> <p>Here’s what the evidence says and what we should really be focusing on.</p> <h2>Remind me, what actually is blue light?</h2> <p>Blue light is part of the visible light spectrum. Sunlight is the strongest source. But our electronic devices – such as our phones, laptops and TVs – also emit it, albeit at levels <a href="https://melasmaclinic.com.au/wp-content/uploads/2024/01/Melasma-LEDS.pdf">100-1,000 times</a> lower.</p> <p>Seeing as we spend so much time using these devices, there has been some concern about the impact of blue light on our health, including <a href="https://theconversation.com/do-blue-light-glasses-really-work-can-they-reduce-eye-strain-or-help-me-sleep-213145">on our eyes and sleep</a>.</p> <p>Now, we’re learning more about the impact of blue light on our skin.</p> <h2>How does blue light affect the skin?</h2> <p>The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings.</p> <p><strong>1. Blue light can increase pigmentation</strong></p> <p><a href="https://academic.oup.com/ced/article-abstract/46/5/934/6598472?redirectedFrom=fulltext&amp;login=false">Studies</a> <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/srt.13401">suggest</a> exposure to blue light can stimulate production of melanin, the natural skin pigment that gives skin its colour.</p> <p>So too much blue light can potentially worsen hyperpigmentation – overproduction of melanin leading to dark spots on the skin – especially in people with darker skin.</p> <p><strong>2. Blue light can give you wrinkles</strong></p> <p>Some research <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6280109/">suggests</a> blue light might damage collagen, a protein essential for skin structure, potentially accelerating the formation of wrinkles.</p> <p>A laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/29399830/">study suggests</a> this can happen if you hold your device one centimetre from your skin for as little as an hour.</p> <p>However, for most people, if you hold your device more than 10cm away from your skin, that would reduce your exposure <a href="https://en.wikipedia.org/wiki/Inverse-square_law">100-fold</a>. So this is much less likely to be significant.</p> <p><strong>3. Blue light can disrupt your sleep, affecting your skin</strong></p> <p>If the skin around your eyes looks dull or puffy, it’s easy to blame this directly on blue light. But as we know blue light affects sleep, what you’re probably seeing are some of the visible signs of sleep deprivation.</p> <p>We know blue light is particularly good at <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.01413.2009?rss=1">suppressing</a> production of melatonin. This natural hormone normally signals to our bodies when it’s time for sleep and helps regulate our sleep-wake cycle.</p> <p>By suppressing melatonin, blue light exposure before bed disrupts this natural process, making it harder to fall asleep and potentially reducing the <a href="https://www.tandfonline.com/doi/abs/10.1080/07420528.2023.2173606">quality of your sleep</a>.</p> <p>The stimulating nature of screen content further disrupts sleep. Social media feeds, news articles, video games, or even work emails can keep our brains active and alert, hindering the transition into a sleep state.</p> <p>Long-term sleep problems can also <a href="https://academic.oup.com/ced/article-abstract/40/1/17/6621145?login=false">worsen</a> existing skin conditions, such as acne, eczema and rosacea.</p> <p>Sleep deprivation can elevate cortisol levels, a stress hormone that breaks down collagen, the protein responsible for skin’s firmness. Lack of sleep can also weaken the skin’s natural barrier, making it more susceptible to environmental damage and dryness.</p> <h2>Can skincare protect me?</h2> <p>The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses.</p> <p>From a practical perspective, probably only those with the more troublesome hyperpigmentation known as <a href="https://dermnetnz.org/topics/melasma">melasma</a> need to be concerned about blue light from devices.</p> <p>This condition requires the skin to be well protected from all visible light at all times. The only products that are totally effective are those that block all light, namely mineral-based suncreens or some cosmetics. If you can’t see the skin through them they are going to be effective.</p> <p>But there is a lack of rigorous testing for non-opaque products outside laboratories. This makes it difficult to assess if they work and if it’s worth adding them to your skincare routine.</p> <h2>What can I do to minimise blue light then?</h2> <p>Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep:</p> <ul> <li> <p>use the “night mode” setting on your device or use a blue-light filter app to reduce your exposure to blue light in the evening</p> </li> <li> <p>minimise screen time before bed and create a relaxing bedtime routine to avoid the types of sleep disturbances that can affect the health of your skin</p> </li> <li> <p>hold your phone or device away from your skin to minimise exposure to blue light</p> </li> <li> <p>use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light.</p> </li> </ul> <h2>In a nutshell</h2> <p>Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing.</p> <p>While skincare to protect against blue light shows promise, more testing is needed to determine if it works.</p> <p>For now, prioritise good sun protection with a broad-spectrum sunscreen, which not only protects against UV, but also light.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233335/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, Associate Professor of Dermatology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

<p><em><a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan.</p> <p>f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>.</p> <p>But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge.</p> <p>Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community.</p> <p>This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California.</p> <p>Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>.</p> <p>Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>.</p> <p>However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life.</p> <h2>Is the secret in our diet?</h2> <p>When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones.</p> <p>For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease.</p> <p>In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age.</p> <p>Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity.</p> <p>But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses.</p> <p>Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>.</p> <p>Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity.</p> <p>Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing.</p> <p>There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life.</p> <p>Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing.</p> <p>Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221463/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, Professor of Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, PhD Candidate in Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, Senior Lecturer in Public Health and Nutrition, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do blue-light glasses really work? Can they reduce eye strain or help me sleep?

<p><em><a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>Blue-light glasses are said to <a href="https://www.baxterblue.com.au/collections/blue-light-glasses">reduce eye strain</a> when using <a href="https://www.blockbluelight.com.au/collections/computer-glasses">computers</a>, improve your <a href="https://www.ocushield.com/products/anti-blue-light-glasses">sleep</a> and protect your eye health. You can buy them yourself or your optometrist can prescribe them.</p> <p>But <a href="https://mivision.com.au/2019/03/debate-continues-over-blue-blocking-lenses/">do they work</a>? Or could they do you harm?</p> <p>We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found.</p> <h2>What are they?</h2> <p>Blue-light glasses, blue light-filtering lenses or blue-blocking lenses are different terms used to describe lenses that reduce the amount of short-wavelength visible (blue) light reaching the eyes.</p> <p>Most of these lenses prescribed by an optometrist decrease blue light transmission by <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">10-25%</a>. Standard (clear) lenses do not filter blue light.</p> <p>A wide variety of lens products are available. A filter can be added to prescription or non-prescription lenses. They are widely marketed and are becoming <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">increasingly popular</a>.</p> <p>There’s often an added cost, which depends on the specific product. So, is the extra expense worth it?</p> <h2>Blue light is all around us</h2> <p>Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light.</p> <p>The amount of blue light emitted from artificial light sources is much lower than from the Sun. Nevertheless, artificial light sources are all around us, at home and at work, and we can spend a lot of our time inside.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption><span class="caption">Screens emit blue light.

So we conducted a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">systematic review</a> to bring together and evaluate all the relevant studies.</p> <p>We included all randomised controlled trials (clinical studies designed to test the effects of interventions) that evaluated blue light-filtering lenses in adults. We identified 17 eligible trials from six countries, involving a total of 619 adults.</p> <h2>Do they reduce eye strain?</h2> <p>We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use.</p> <p>This conclusion was based on consistent findings from three studies that evaluated effects on eye strain over time periods ranging from two hours to five days.</p> <h2>Do they help you sleep?</h2> <p>Possible effects on sleep were uncertain. Six studies evaluated whether wearing blue-light filtering lenses before bedtime could improve sleep quality, and the findings were mixed.</p> <p>These studies involved people with a diverse range of medical conditions, including insomnia and bipolar disorder. Healthy adults were not included in the studies. So we do not yet know whether these lenses affect sleep quality in the general population.</p> <h2>Do they boost your eye health?</h2> <p>We did not find any clinical evidence to support using blue-light filtering lenses to protect the macula (the region of the retina that controls high-detailed, central vision).</p> <p>None of the studies evaluated this.</p> <h2>Could they do harm? How about causing headaches?</h2> <p>We could not draw clear conclusions on whether there might be harms from wearing blue light-filtering lenses, compared with standard (non blue-light filtering) lenses.</p> <p>Some studies described how study participants had headaches, lowered mood and discomfort from wearing the glasses. However, people using glasses with standard lenses reported similar effects.</p> <h2>What about other benefits or harms?</h2> <p>There are some important general considerations when interpreting our findings.</p> <p>First, most of the studies were for a relatively short period of time, which limited our ability to consider longer-term effects on vision, sleep quality and eye health.</p> <p>Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children.</p> <p>Finally, we could not draw conclusions about the possible effects of blue light-filtering lenses on many vision and eye health measures, including colour vision, as the studies did not evaluate these.</p> <h2>In a nutshell</h2> <p>Overall, based on relatively limited published clinical data, our review does not support using blue-light filtering lenses to reduce eye strain with digital device use. It is unclear whether these lenses affect vision quality or sleep, and no conclusions can be drawn about any potential effects on the health of the retina.</p> <p>High-quality research is needed to answer these questions, as well as whether the effectiveness and safety of these lenses varies in people of different ages and health status.</p> <p>If you have eye strain, or other eye or vision concerns, discuss this with your optometrist. They can perform a thorough examination of your eye health and vision, and discuss any relevant treatment options.<!-- Below is The Conversation's page counter tag.

How to beat the retirement blues

<p>When people plan their retirement they don’t usually expect Post retiring depression (PRD). This kind of depression usually stems from dashed expectations, financial trouble or feeling lost and lonely. That’s why we’ve got four top tips to avoid PRD and enjoy your free time.</p> <p><strong>1. Plan it out</strong></p> <p>Know what you want to do, not what you think you should be doing. Don’t hold back in indulging yourself, travelling the world, volunteering abroad – the temporary discomfort of not knowing is better than realising when it’s too late that you never completed your bucket list.</p> <p><strong>2. Routine</strong></p> <p>A sudden lack of structure can become exhausting or at least unsettling. Schedule activities such as exercise, housework, errands, and social time. Then let the day flow from there.</p> <p><strong>3. Keep active</strong></p> <p>There is a lot of research to show that the people who cope best with retirement are those who stay active and involved. This might include:</p> <ul> <li>Developing an old hobby or starting a new one. </li> <li>Staying physically active, through walking, swimming, gym or sport. Make sure your exercise routine is appropriate for your physical capacities and limitations. </li> <li>Volunteering with a charity or church group. </li> <li>Working part-time. </li> <li>Studying a course.</li> </ul> <p><strong>4. Stay in touch</strong></p> <p>Loneliness and isolation can be easily avoided, so don’t fall into the trap of feeling alone. Make the effort to stay in contact with family and friends. Offer to babysit your grandchildren. Check out local community centres for upcoming activities you might enjoy. Even if you're not sure try something new, you might surprise yourself!</p> <p><em>Images: Getty</em></p>

"I fell for it!": Boys in blue crash gender reveal party

<p>One Sydney couple have taken their friends and family by surprise with their high-stakes gender reveal, where the father-to-be was apparently put under arrest by two police officers. </p> <p>Mina Ibrahim revealed their elaborate prank with a video posted to his TikTok account. Mina’s video begins with footage of the moment of his ‘arrest’, before it cuts to the TikToker at a later date, explaining that “that’s me being arrested at my baby’s gender reveal.” </p> <p>He goes on to share the full video, and a promise that the ending will answer any questions his viewers may have.</p> <p>In the clip, the parents-to-be can be seen talking to two uniformed NSW ‘police officers’, guests all around them, with Mina asking for onlookers to get their phones out. He then pushes one of the officers, telling them to leave, and both grab him before attempting to handcuff him, while his pregnant partner attempts to intervene. </p> <p>As family members rush to assist, one of the officers calls for everyone to calm down, then delivers news that takes them all by surprise - and delight - by telling them, “it’s a baby girl.” </p> <p>“So it was the cops who announced to everyone that I was having a baby girl,” present-day Mina informed his audience, before noting that there was a fake balloon inside to throw their guests off the surprise scent. </p> <div class="mol-embed" style="margin: 0px 0px 8px; padding: 0px; min-height: 1px; letter-spacing: -0.16px; text-align: center; font-family: graphik, Arial, sans-serif; font-size: 16px; background-color: #ffffff;"> <blockquote id="v34606683345148116" class="tiktok-embed" style="margin: 18px auto; padding: 0px; min-height: 1px; letter-spacing: -0.01em; position: relative; width: 605px; box-sizing: border-box; line-height: 1.15; overflow: hidden; text-size-adjust: 100%; font-family: proxima-regular, PingFangSC, sans-serif; max-width: 605px; min-width: 325px;" cite="https://www.tiktok.com/@mina.ibs/video/7232964823296773383" data-video-id="7232964823296773383" data-embed-from="oembed"><p><iframe style="letter-spacing: -0.01em; border-width: initial; border-style: none; width: 605px; height: 735px; display: block; visibility: unset; max-height: 735px;" src="https://www.tiktok.com/embed/v2/7232964823296773383?lang=en-GB&amp;referrer=https%3A%2F%2Fwww.dailymail.co.uk%2Fnews%2Farticle-12082153%2FGender-reveal-party-prank-sees-cops-arrest-father-be.html&amp;embedFrom=oembed" name="__tt_embed__v34606683345148116" sandbox="allow-popups allow-popups-to-escape-sandbox allow-scripts allow-top-navigation allow-same-origin"></iframe></p></blockquote> </div> <p>The prank attracted thousands of views online, with many flocking to his comments section to share their congratulations with the parents-to-be. </p> <p>Others, while thrilled for them and their happy news, were open about their concern, having fallen for the trick right along with the couple’s loved ones. </p> <p>“I fell for it and I was worried for your wife!!!,” one confessed. “I was freaking out hahahah you got me”.</p> <p>“I was worried too haha … you scared me,” another said. </p> <p>“Omygosh! I was ready to sue them coppas with you!” came one response, “but congratsss! What a way to reveal!”</p> <p>One other simply wanted to know if the entire situation was even allowed, believing that impersonating the police may not be. </p> <p>And another had simply been suspicious from the very start, noting “Broooo the whole time I was like … something ain’t right! He’s not carrying his gun”.</p> <p><em>Images: TikTok</em></p>

Aussie author of "Puberty Blues" dies at 64

<p dir="ltr">Gabrielle Carey, co-author of the iconic novel <em>Puberty Blues</em>, has passed away at 64. </p> <p dir="ltr">The news was reportedly broken by Carey’s old friend and co-writer Kathy Lette, who was the other half of the creative powerhouse that brought<em> Puberty Blues </em>to life. </p> <p dir="ltr">In a post to social media, Lette shared a throwback picture of the pair in their younger years, and wrote, “I’m deeply saddened by the tragic news about my old friend Gabrielle Carey. </p> <p dir="ltr">“I have such happy memories of our teenage years.

Don’t say cheese! Travel destinations where photos are illegal

<p dir="ltr">While many happy travellers love to immortalise their holiday with a collection of photos, there are some places that don’t allow for pics to be taken. </p> <p dir="ltr">In several destinations across the globe, tourists are actually banned from taking selfies and can even get fined for breaking the rules.</p> <p dir="ltr">So before you pull out your camera and strike a pose, you might want to check if what you’re snapping a photo of is legal. </p> <p dir="ltr">Here are just a few places where taking photos isn’t allowed. </p> <p><strong>The Sistine Chapel, Vatican City</strong></p> <p dir="ltr">The use of professional cameras and phones is strictly prohibited in the Sistine Chapel so don't even think about it. </p> <p dir="ltr">According to <a href="https://www.vaticancitytours.it/blog/are-cameras-allowed-in-the-vatican-city/#:~:text=Sistine%20Chapel&amp;text=The%20real%20reason%20for%20the,companies%20to%20fund%20the%20project.">VaticanCityTours,</a> the reason you can't take pictures dates back to 1980 when the chapel was restored due to damage caused by flash photography. </p> <p dir="ltr"><strong>Mecca Pilgrimage, Saudi Arabia</strong></p> <p dir="ltr">In Saudi Arabia, it is against the law to take photos of worshippers during Hajj, otherwise known as their pilgrimage to the holy city of Mecca. </p> <p>This is due to it being disrespectful to snap people while they are on their religious journey. </p> <p dir="ltr"><strong>The Blue Mosque, Turkey</strong></p> <p>Taking a photo of the outside of the iconic Blue Mosque is totally okay, but snapping any photos of the interior is a big no. </p> <p>Visitors also must follow strict dress codes as well as other rules and regulations.</p> <p dir="ltr"><strong>Anne Frank's House, Amsterdam</strong></p> <p>Taking photos or selfies in the House of Anne Frank is not allowed inside the museum due to its serious nature.</p> <p>There is a very sombre mood within the historical house, making it a time for reflection, not for flash photography. </p> <p dir="ltr"><strong>Palace of Versailles, France</strong></p> <p>Photos of both the Palace and the surrounding gardens are strictly prohibited for all travellers. </p> <p>This is due to concerns about the preservation of artwork and the safety of visitors.</p> <p dir="ltr"><strong>Garoupe Beach, France</strong></p> <p>The famous Garoupe beach in southern France banned holidaymakers from taking selfies during the busy season in the middle of summer.</p> <p dir="ltr">The law was first introduced to stop people from bragging about their holiday and just enjoy the stay rather than show off on social media.</p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

Can you freeze cheese?

<p>Dairy products are notoriously fussy when it comes to freezing. But when there’s a great sale at the supermarket, it’s hard to resist the siren call of a big discounted brick of cheese. It doesn’t last forever in the refrigerator, but can you freeze cheese?</p> <p>Yes – sometimes! The general rule of thumb is that freezing cheese will likely change its texture. If you do opt to freeze extra cheese, its best use after thawing is for cooking– the texture change becomes a moot point after it’s all melted. You probably don’t want to freeze the fancy stuff you bought for snacking on with homemade crackers, though. But frozen cheese, once thawed, would be perfect in a cheesy bake or casserole recipe.</p> <p><strong>Can you freeze mozzarella?</strong></p> <p>Blocks of mozzarella or shredded mozzarella are fine to freeze, though they tend to have a crumbly texture after freezing. Just avoid freezing fresh mozzarella, as its high water content has a likelihood of forming ice crystals.</p> <p><strong>Can you freeze cottage cheese?</strong></p> <p>Cottage cheese, along with ricotta cheese, can be frozen. However, upon thawing, both cheeses are likely to have a grainier texture. As with most frozen cheeses, thawed cottage and ricotta cheeses are best used in baked or cooked recipes.</p> <p><strong>Can you freeze cheese slices?</strong></p> <p>Yep! For prepackaged sliced cheese, just pop the package into a freezer bag and place it in the freezer. For deli-sliced cheese, place a piece of parchment paper in between each slice of cheese. Then wrap the cheese in freezer paper, tape shut and place the whole package in a freezer bag or freezer-safe container.</p> <p><strong>Can you freeze shredded cheese?</strong></p> <p>For prepackaged shredded cheese, place the package in a freezer bag before putting it in the freezer. For cheese you shred or grate yourself, place it in a freezer bag and carefully remove as much air as possible from the bag.</p> <p>This article originally appeared on <a href="https://www.readersdigest.com.au/kitchen-tips/can-you-freeze-cheese-yes-heres-what-you-need-to-know" target="_blank" rel="noopener">Reader's Digest</a>.</p> <p><em><span style="color: #444444; font-family: Raleway, sans-serif, 'Helvetica Neue', Helvetica, Arial; font-size: 16px; background-color: #ffffff;">Image: Getty</span></em></p> <p><em><span style="color: #444444; font-family: Raleway, sans-serif, 'Helvetica Neue', Helvetica, Arial; font-size: 16px; background-color: #ffffff;"> </span></em></p>

Warming oceans may force New Zealand’s sperm and blue whales to shift to cooler southern waters

<p>The world’s oceans are absorbing more than <a href="https://www.un.org/en/climatechange/science/climate-issues/ocean-impacts" target="_blank" rel="noopener">90% of the excess heat and energy</a> generated by rising greenhouse gas emissions.</p> <p>But, as the oceans keep warming, rising sea temperatures generate unprecedented cascading effects that include the melting of polar ice, rising seas, marine heatwaves and ocean acidification.</p> <p>This in turn has profound impacts on marine biodiversity and the lives and livelihoods of coastal communities, especially in island nations such as New Zealand.</p> <p>In our latest <a href="https://www.sciencedirect.com/science/article/pii/S1470160X22007075?via%3Dihub" target="_blank" rel="noopener">research</a>, we focused on great whales – sperm and blue whales in particular. They are crucial for maintaining healthy marine ecosystems, but have limited options to respond to climate change: either adapt, die, or move to stay within optimal habitats.</p> <p>We used mathematical models to predict how they are likely to respond to warming seas by the end of the century. Our results show a clear southward shift for both species, mostly driven by rising temperatures at the sea surface.</p> <h2>Computing the fate of whales</h2> <p>Data on the local abundance of both whales species are <a href="https://www.int-res.com/abstracts/meps/v690/p201-217/" target="_blank" rel="noopener">deficient</a>, but modelling provides a powerful tool to predict how their range is likely to shift.</p> <p>We used a <a href="http://macroecointern.dk/pdf-reprints/AraujoNew2007.pdf" target="_blank" rel="noopener">combination of mathematical models</a> (known as correlative species distribution models) to predict the future range shifts of these whale species as a response to three future climate change scenarios of differing severity, as outlined by the Intergovernmental Panel on Climate Change (<a href="https://www.ipcc.ch/" target="_blank" rel="noopener">IPCC</a>).</p> <p>We applied these models, using the whales’ present distributions, to build a set of environmental “rules” that dictate where each species can live. Using climate-dependent data such as sea-surface temperature and chlorophyll A (a measure of phytoplankton growth), as well as static data such as water depth and distance to shore, we applied these rules to forecast future habitat suitability.</p> <p>We chose a scenario of “<a href="https://www.nature.com/articles/d41586-020-00177-3" target="_blank" rel="noopener">modest</a>” response to cutting greenhouse gas emissions (the IPCC’s mitigation strategy RCP4.5), which is the most likely given the current policies, and a worst-case scenario (no policy to cut emissions, RCP8.5), assuming the reality will likely be somewhere between the two.</p> <p>Our projections suggest current habitats in the ocean around the North Island may become unsuitable if sea-surface temperatures continue to rise.</p> <p>These range shifts become even stronger with increasing severity of climate change. For sperm whales, which are currently abundant off Kaikōura where they support eco-tourism businesses, the predicted distribution changes are even more evident than for blue whales, depending on the climate change scenario.</p> <p>While our results do not predict an overall reduction in suitable habitat that would lead to local extinctions, the latitudinal range shifts are nevertheless bound to have important ecological consequences for New Zealand’s marine ecosystems and the people who depend on them.</p> <h2>How whales maintain ecosystems</h2> <p>Great whales are marine ecosystem engineers. They modify their habitats (or create new ones), to suit their needs. In fact, these activities create conditions that other species rely on to survive.</p> <p>They engineer their environment on several fronts. By feeding in one place and releasing their faeces in another, whales convey minerals and other nutrients such as nitrogen and iron from the deep water to the surface, as well as across regions. This process, known as a “<a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0013255" target="_blank" rel="noopener">whale pump</a>”, makes these nutrients available for phytoplankton and other organisms to grow.</p> <p>This is very important because phytoplankton contributes about <a href="https://education.nationalgeographic.org/resource/plankton-revealed" target="_blank" rel="noopener">half of all oxygen to the atmosphere</a> and also captures <a href="https://www.imf.org/Publications/fandd/issues/2019/12/natures-solution-to-climate-change-chami" target="_blank" rel="noopener">about 40% of all released carbon dioxide</a>. By helping the growth of phytoplankton, whales indirectly contribute to the <a href="https://theconversation.com/tiny-plankton-drive-processes-in-the-ocean-that-capture-twice-as-much-carbon-as-scientists-thought-136599" target="_blank" rel="noopener">natural ocean carbon sink</a>.</p> <p>On top of this, each great whale accumulates about <a href="https://www.arcticwwf.org/the-circle/stories/protecting-the-earth-by-protecting-whales/" target="_blank" rel="noopener">33 tonnes of carbon dioxide in their body</a>, which they take to the ocean floor when they die and their carcass sinks.</p> <p> </p> <figure></figure> <p> </p> <p>Ultimately, the impact of warming oceans on whale distribution is an additional stress factor on ecosystems already under pressure from wider threats, including acidification, pollution and over-exploitation.</p> <h2>A way forward to help whales</h2> <p>Sperm whales are the largest toothed whales (odontocetes) and deep-diving apex predators. They primarily feed on squid and fish that live near the bottom of the sea.</p> <p>Blue whales are baleen whales (mysticetes) and filter small organisms from the water. They feed at the surface on zooplankton, particularly dense krill schools along coastlines where cold water from the deep ocean rises toward the surface (so-called <a href="https://oceanservice.noaa.gov/facts/upwelling.html" target="_blank" rel="noopener">upwelling areas</a>).</p> <p>These differences in feeding habits lead to divergent responses to ocean warming. Blue whales show a more distinct southerly shift than sperm whales, particularly in the worst-case scenario, likely because they feed at the surface where ocean warming will be more exacerbated than in the deep sea.</p> <p>Both species have important foraging grounds off New Zealand which may be compromised in the future. Sperm whales are currently occurring regularly off Kaikōura, while blue whales forage in the South Taranaki Bight.</p> <p>Despite these ecological differences, our results show that some future suitable areas around the South Island and offshore islands are common to both species. These regions could be considered sanctuaries for both species to retreat to or expand their habitat in a warming world.

How to roll away all your sore back blues

<p>We all know that working a 9-5 and sitting all day leads to various health problems. For me personally, it manifests itself through chronic back pain and tight hip flexors. </p> <p>Fortunately, there's a way for me to soothe these aches and pains from home. I've been using <a href="https://www.therabody.com/anz/en-nz/wave-roller-anz.html" target="_blank" rel="noopener">Therabody's Wave Roller</a> for the past week, and my back pain has significantly reduced. </p> <p>The Wave Roller is a Bluetooth-enabled vibrating foam roller that proposes benefits like increasing blood flow, enhancing mobility, and releasing tension. You can connect the roller to a free Therabody App, where you can find personalised recovery routines targeting all parts of your body, along with instructions and how-tos. </p> <p>Here are some of my initial thoughts. </p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/03/03_RizWaveroller01.jpg" alt="Therabody Wave Roller in use" width="1280" height="720" /></p> <p>My personal favourites are the mid back and upper back routines, which take up to 5 minutes to complete. Since most of the tension is in my upper body, which causes my lower back to overcompensate, I've decided to focus on these areas. </p> <p>The foam roller comes with a bag and charger and is reasonably lightweight, so you could easily carry it around. The foam itself is a high-density foam, and I like that you can customise the intensity and frequency of the vibrations. </p> <p>There are five customised vibration settings, with 5 being the highest and most intense. I could only handle up to the third setting or the medium-intensity.</p> <p>But, the higher the intensity, the more noise it produces, although I didn't mind it so much for the other benefits it provided. </p> <p>The routines are easy to follow, with pictures demonstrating each move and seamless transitions from one exercise to the next. I also liked that the intensity of the vibrations automatically changes according to what's best for that particular movement. </p> <p>I would have loved seeing a video demonstration before each routine, as I wasn't sure if I was doing some of the exercises quite correctly. </p> <p>I also found that the Wave Roller can be slippery to use in some movements, like when I tried it on my rotator cuffs. </p> <p>Despite this, the Wave Roller is a pleasure to use after a long day, when my muscles are the most tense. I find it a helpful tool in managing pain, soreness, and releasing tension. </p> <p>Although it is on the higher end of the price range compared to other foam rollers, I think it's worth the investment. The technology is advanced, and you can personalise the areas you want to work on using the step-by-step programs in their app. </p> <p>It also feels like you're getting a massage, but it's more personalised and customisable. </p> <p>If using the app seems intimidating or too complicated, you can use the Wave Roller by itself and adjust the intensity using the + and - buttons. </p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/03/02_RizWaveroller.jpg" alt="Therabody Wave Roller" width="1280" height="720" /></p> <p>In summary, here are the pros and cons to consider if you're thinking of purchasing one for yourself. </p> <p><strong>Pros: </strong></p> <ul> <li>Relieves soreness and muscle tension</li> <li>Variety of settings for the vibrations</li> <li>App integration </li> <li>Personalised programs that are quick and easy to follow</li> <li>3-hour battery life and it doesn’t take too long to charge</li> </ul> <p><strong>Cons: </strong></p> <ul> <li>The cost (RRP AU$249), but worth every penny! </li> <li>Medium to High setting intense and pretty noisy </li> <li>Depending on the exercise you do it can be quite slippery</li> <li>Video demonstrations before each exercise would be even better </li> </ul> <p>The Wave Roller series is available via the <a href="https://www.therabody.com/anz/en-nz/home" target="_blank" rel="noopener">Therabody website</a>. </p> <p>Images: Rizna Mutmainah &amp; Therabody</p>

Man charged with murder of missing 9-year-old

<p><em>Image: NSW Police </em></p> <p>A man has been charged with murder after nine-year-old Charlise Mutten disappeared from the Blue Mountains last Thursday.</p> <p>Police have arrested a 32-year-old at a unit in Surry Hills, in central Sydney, at about 8:30 pm on Tuesday evening, and he is due to appear in Central Local Court late on Wednesday.</p> <p>NSW Police established Strike Force Buena to investigate Charlise's disappearance.</p> <p>Last Friday morning she was reported missing, officers last night carried out a search at Colo River, about an hour from the Blue Mountains. It is unclear if anything was found.</p> <p>The young girl was a student from Tweed Heads Public School, who lived with her grandmother in Coolangatta, Queensland. She was holidaying in the Blue Mountains with her mother, Kallista Mutten.</p> <p>The pair were staying at a wedding and function venue when she disappeared last Thursday afternoon. Ms Mutten reported her daughter missing the next morning but police haven't revealed whether she was formally interviewed since she was hospitalised for a medical condition.</p> <p>NSW homicide detectives joined the investigation on Monday. Volunteers helping with the search were instructed to call out Charlise's name loudly and told to flag any evidence with police before touching it.</p> <p>They were also told to search for anything out of the ordinary including footprints or bike tracks. A large-scale search had been underway in the area since late last week, with a hundred emergency services staff on the ground and in the air.</p> <p>Police divers spent hours searching the Hawkesbury River in Windsor, with Rural Fire Service (RFS) volunteers also joined the search.</p> <p>On Monday morning police searched a cubby house on a neighbouring property but found nothing.</p>
