Why do I get so anxious after drinking? Here’s the science behind ‘hangxiety’

<p><em><a href="https://theconversation.com/profiles/blair-aitken-1510537">Blair Aitken</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rebecca-rothman-2231560">Rebecca Rothman</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>You had a great night out, but the next morning, anxiety hits: your heart races, and you replay every conversation from the night before in your head. This feeling, known as hangover anxiety or “<a href="https://adf.org.au/insights/what-is-hangxiety/">hangxiety</a>”, <a href="https://onlinelibrary.wiley.com/doi/10.1002/hup.2623">affects around 22%</a> of social drinkers.</p> <p>While for some people, it’s mild nerves, for others, it’s a wave of anxiety that feels impossible to ride out. The “Sunday scaries” may make you feel panicked, filled with dread and unable to relax.</p> <p>Hangover anxiety can make even simple tasks feel overwhelming. Here’s why it happens, and what you can do about it.</p> <h2>What does alcohol do to our brains?</h2> <p>A hangover is the body’s way of recovering after drinking alcohol, bringing with it a range of symptoms.</p> <p><a href="https://www.mdpi.com/2077-0383/10/23/5691">Dehydration and disrupted sleep</a> play a large part in the pounding headaches and nausea many of us know too well after a big night out. But hangovers aren’t just physical – there’s a strong mental side too.</p> <p>Alcohol is a nervous system depressant, meaning it alters how certain chemical messengers (or neurotransmitters) behave in the brain. Alcohol relaxes you by increasing <a href="https://my.clevelandclinic.org/health/articles/22857-gamma-aminobutyric-acid-gaba">gamma-aminobutyric acid</a> (GABA), the neurotransmitter that makes you feel calm and lowers inhibitions. It decreases <a href="https://my.clevelandclinic.org/health/articles/22839-glutamate">glutamate</a> and this also slows down your thoughts and helps ease you into a more relaxed state.</p> <p>Together, this interaction affects your mood, emotions and alertness. This is why when we drink, we often feel more sociable, carefree and willing to let our guard down.</p> <p>As the effects of the alcohol wear off, your brain works to rebalance these chemicals by <a href="https://www.sciencedirect.com/science/article/pii/S0191886918305762">reducing GABA and increasing glutamate</a>. This shift has the opposite effect of the night before, causing your brain to become more excitable and overstimulated, which can lead to feelings of anxiety.</p> <p>So why do some people get hangxiety, while others don’t? There isn’t one clear answer to this question, as several factors can play a role in whether someone experiences hangover-related anxiety.</p> <h2>Genes play a role</h2> <p>For some, a hangover is simply a matter of how much they drank or how hydrated they are. But genetics may also play a significant role. <a href="https://onlinelibrary.wiley.com/doi/10.1111/add.12699">Research</a> shows your genes can explain almost half the reason why you wake up feeling hungover, while your friend might not.</p> <p>Because genes influence how your body processes alcohol, some people may experience more intense hangover symptoms, such as headaches or dehydration. These stronger physical effects can, in turn, <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1002/hup.2623">trigger anxiety during a hangover</a>, making you more susceptible to “hangxiety.”</p> <h2>Do you remember what you said last night?</h2> <p>But one of the most common culprits for feeling anxious the next day is often <a href="https://journals.sagepub.com/doi/pdf/10.1177/0091450915604988">what you do while drinking</a>.</p> <p>Let’s say you’ve had a big night out and you can’t quite recall a conversation you had or something you did. Maybe you acted in ways that you now regret or feel embarrassed about. You might fixate on these thoughts and get trapped in a cycle of worrying and rumination. This cycle can be hard to break and can make you feel more anxious.</p> <p><a href="https://doi.org/10.1016/j.addbeh.2023.107619">Research</a> suggests people who already struggle with feelings of anxiety in their day-to-day lives are especially vulnerable to hangxiety.</p> <p>Some people drink alcohol to unwind after a stressful day or to make themselves feel more comfortable at social events. This often leads to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9756407">heavier consumption</a>, which can make hangover symptoms more severe. It can also begin a cycle of drinking to feel better, making hangxiety even harder to escape.</p> <h2>Preventing hangover anxiety</h2> <p>The best way to prevent hangxiety is to limit your alcohol consumption. The <a href="https://adf.org.au/reducing-risk/alcohol/alcohol-guidelines">Australian guidelines</a> recommend having no more than ten standard drinks per week and no more than four standard drinks on any one day.</p> <p>Generally, the more you drink, the more intense your hangover symptoms might be, and the worse you are likely to feel.</p> <p>Mixing other drugs with alcohol can also increase the risk of hangxiety. This is especially true for party drugs, such as ecstasy or MDMA, that give you a temporary high but can lead to anxiety as they wear off and you are <a href="https://adf.org.au/insights/drug-comedowns">coming down</a>.</p> <p>If you do wake up feeling anxious:</p> <ul> <li> <p>focus on the physical recovery to help ease the mental strain</p> </li> <li> <p>drink plenty of water, eat a light meal and allow yourself time to rest</p> </li> <li> <p>try <a href="https://www.headspace.com/mindfulness/mindfulness-101">mindfulness meditation</a> or deep breathing exercises, especially if anxiety keeps you awake or your mind races</p> </li> <li> <p>consider journalling. This can help re-frame anxious thoughts, put your feelings into perspective and encourage self-compassion</p> </li> <li> <p>talk to a close friend. This can provide a safe space to express concerns and feel less isolated.</p> </li> </ul> <p>Hangxiety is an unwelcome guest after a night out. Understanding why hangxiety happens – and how you can manage it – can make the morning after a little less daunting, and help keep those anxious thoughts at bay.<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/240991/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/blair-aitken-1510537">Blair Aitken</a>, Postdoctoral Research Fellow in Psychopharmacology, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rebecca-rothman-2231560">Rebecca Rothman</a>, PhD Candidate in Clinical Psychology, School of Health Sciences, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</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.

What is ‘doll therapy’ for people with dementia? And is it backed by science?

Original Bee Gees star passes away aged 78

<p>Colin ‘Smiley’ Petersen has passed away aged 78. </p> <p>News of his death was posted on the official Facebook page of tribute band Best of the Bee Gees. </p> <p>“It is with a heavy heart we announce the passing of our dear friend Colin ‘Smiley’ Petersen,” they began. </p> <p>“He enriched our lives and bound our group with love, care and respect.</p> <p>“Not sure how we can go on without his glowing smile and deep friendship. We love you Col. Rest in Peace.”</p> <p>Petersen who was one of the original members of Australian band Bee Gees was born in Kingaroy, Queensland, has been credited for contributing to the band's rise to global superstardom. </p> <p>He was the band's first drummer and performed some of their most beloved songs including <em>Massachusetts, To Love Somebody</em> and <em>Words</em>.</p> <p>Petersen attended the same school in Redcliffe, Queensland as bandmates and brothers Barry Robin and Maurice Gibb, where he first developed an interest in music. </p> <p>After graduating, Petersen moved to the UK to break into the film industry, before he joined the Bee Gees in the 60's becoming the first non-Gibb brother to join the group. </p> <p>“There was an understanding that when the Gibbs’ arrived in England, that if the film thing didn’t work out, I’d join their band,” Petersen told Geelong Independent in 2022.</p> <p>“So I became the fourth Bee Gee, and that was obviously a big turning point in my life.”</p> <p>He left the band after the first phase of their career, just before they reached peak stardom in the '70s disco era, due to conflicts with the group's then-manager Robert Stigwood.</p> <p>Petersen moved back to Australia with his family in 1974, and in 2019 he joined the tribute group Best of the Bee Gees.</p> <p>His death comes after Maurice's sudden death in 2003, which prompted the Bee Gees to retire after 45 years. </p> <p>Robin later died in 2012 aged 62, leaving Barry, Vince Melouney and Geoff Bridgford as the last surviving members of the group.</p> <p>Petersen is survived by his ex-wife Joanne Newfield and their sons Jaime, born in 1971, and Ben, born in 1976.</p> <p><em>Image: </em><em>Everett Collection</em><em style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">/ Shutterstock Editorial</em></p> <p> </p>

Full House star's devastating cancer diagnosis

<p>Dave Coulier has revealed his devastating cancer diagnosis </p> <p>The <em>Full House</em> star told the <em>US Toda</em>y show about his "roller coaster" health struggle on Wednesday. </p> <p>After finding out that he was diagnosed with stage 3 non-Hodgkin lymphoma, he said it felt like "I got punched in the stomach because it never happens to you," according to <em>Page Six</em>. </p> <p>Coulier, whose first symptom was a lump in his groin, noted that he was “on pins and needles for a few days” while waiting to hear whether the disease had spread “to any major organs or [his] blood or bones or anything.”</p> <p>While waiting for his results, the 65-year-old actor told his wife, Melissa Coulier that he accepted his fate. </p> <p> “I’m OK with whatever the news [is] going to be no matter how devastating. … I’ve had an incredible life. I’ve had the most amazing people in my life. This has been an extraordinary journey, and I’m OK if this is the end of the journey”.</p> <p>Fortunately the cancer has not moved outside of his lymphatic system, and since then the actor has started chemotherapy, which he said was  “intense” and “scared the daylights” out of him.</p> <p>“There [are] days where I feel unbelievable,” he said. “Then there’s other days where … I’m just going to lay down and let this be what it’s going to be”.</p> <p>Coulier is expected to finish treatment in February 2025 after undergoing six rounds of chemo every three weeks. </p> <p>While the diagnosis was initially shocking, the actor has assured his fans that the curability rate is promising. </p> <p><em>Image: Ralph Dominguez/MediaPunch/ Shutterstock Editorial</em></p> <p> </p>

Matcha is having a moment. What are the health benefits of this green tea drink?

Here’s what the evidence says.</p> <h2>First, what is matcha?</h2> <p><a href="https://www.mdpi.com/1420-3049/26/1/85">Matcha</a> is a finely ground powder of green tea leaves, which come from the plant <em>Camellia sinensis</em>. This is the same plant used to make green and black tea. However, the <a href="https://naokimatcha.com/blogs/articles/how-matcha-is-made-in-japan">production process</a> differentiates matcha from green and black tea.</p> <p>For matcha, the tea plant is grown in shade. Once the leaves are harvested, they’re steamed and dried and the stems are removed. Then the leaves are carefully ground at controlled temperatures to form the powder.</p> <p>The <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6571865/">production process</a> for green tea is simpler. The leaves are picked from the unshaded plants, heated and then dried. We then steep the dried leaves in hot water to get tea (whereas with matcha the whole leaf is consumed).</p> <p>With black tea, after the leaves are picked they’re exposed to air, which leads to oxidation. This makes the leaves black and gives the tea a different flavour.</p> <h2>A source of phytonutrients</h2> <p>Phytonutrients are <a href="https://theconversation.com/phytonutrients-can-boost-your-health-here-are-4-and-where-to-find-them-including-in-your-next-cup-of-coffee-132100">chemical compounds found in plants</a> which have a range of benefits for human health.

Matcha powder similarly has <a href="https://theconversation.com/matcha-tea-what-the-current-evidence-says-about-its-health-benefits-202782">more catechins</a> than green tea. They are strong antioxidants, which <a href="https://link.springer.com/article/10.1186/s41702-020-0057-8">have been shown</a> to have protective effects against bacteria, viruses, allergies, inflammation and cancer. Catechins <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/catechin#:%7E:text=Catechin%20is%20naturally%20present%20in,containing%20many%20catechins%20%5B130%2C131%5D.">are also found</a> in apples, blueberries and strawberries.</p> <h2>What are the actual health benefits?</h2> <p>So we know matcha contains a variety of phytonutrients, but does this translate to noticeable health benefits?</p> <p>A review published in 2023 identified only <a href="https://www.sciencedirect.com/science/article/pii/S2665927122002180">five experimental studies</a> that have given matcha to people. These studies gave participants about 2–4g of matcha per day (equivalent to 1–2 teaspoons of matcha powder), compared to a placebo, as either a capsule, in tea or in foods. Matcha decreased stress and anxiety, and improved memory and cognitive function. There was no effect on mood.</p> <p>A <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0309287">more recent study</a> showed 2g of matcha in older people aged 60 to 85 improved sleep quality. However, in <a href="https://www.mdpi.com/2072-6643/16/17/2907">younger people</a> aged 27 to 64 in another study, matcha had little effect on sleep.</p> <p>A <a href="https://link.springer.com/article/10.1007/s11130-022-00998-9">study in people with obesity</a> found no difference in the weight loss observed between the matcha group and the control group. This study did not randomise participants, and people knew which group they had been placed in.</p> <p>It could be hypothesised that given you consume all of the leaf, and given levels of some phytonutrients may be higher due to the growing conditions, matcha may have more nutritional benefits than green tea. But to my knowledge there has been no direct comparison of health outcomes from green tea compared to matcha.</p> <h2>There’s lots of evidence for green tea</h2> <p>While to date a limited number of studies have looked at matcha, and none compared matcha and green tea, there’s quite a bit of research on the health benefits of drinking green tea.</p> <p>A <a href="https://www.sciencedirect.com/science/article/pii/S0944711317300867?casa_token=dpbAEQQ7Is4AAAAA:U6aggqZM_G0KJ8hkhx0TGSvQywr4utlgKzwUnUj9x5t9eWd-FKENjbTvUv6s4TBTaPYrob-qQkk">systematic review of 21 studies</a> on green tea has shown similar benefits to matcha for improvements in memory, plus evidence for mood improvement.</p> <p>There’s also evidence green tea provides other health benefits. Systematic reviews have shown green tea leads to <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ptr.6697?casa_token=1eAbmeGillYAAAAA%3ABNGBB6EuRFXIDWHgsa7E798wfC0MQK2r3yOmAlFzR2sxyD9Xt837VoCel0l6Tsh3RRO19t-YUm1GqO7Y">weight loss in people with obesity</a>, lower levels of <a href="https://link.springer.com/article/10.1186/s12937-020-00557-5">certain types of cholesterol</a>, and <a href="https://journals.lww.com/md-journal/fulltext/2020/02070/Effect_of_green_tea_supplementation_on_blood.36.aspx/1000">reduced blood pressure</a>. Green tea may also <a href="https://www.nature.com/articles/s41430-020-00710-7">lower the risk of certain types of cancer</a>.</p> <p>So, if you can’t get your hands on matcha at the moment, drinking green tea may be a good way to get your caffeine hit.</p> <p>Although the evidence on green tea provides us with some hints about the health benefits of matcha, we can’t be certain they would be the same. Nonetheless, if your local coffee shop has a good supply of matcha, there’s nothing to suggest you shouldn’t keep enjoying matcha drinks.</p> <p>However, it may be best to leave the matcha croissant or cronut for special occasions. When matcha is added to foods with high levels of added sugar, salt and saturated fat, any health benefits that could be attributed to the matcha may be negated.<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/242775/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, Program Director of Nutrition and Food Sciences, Accredited Practising Dietitian, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</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.

How light can shift your mood and mental health

<p><em><a href="https://theconversation.com/profiles/jacob-crouse-981668">Jacob Crouse</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/emiliana-tonini-1638957">Emiliana Tonini</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ian-hickie-961">Ian Hickie</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>It’s spring and you’ve probably noticed a change in when the Sun rises and sets. But have you also noticed a change in your mood?</p> <p>We’ve known for a while that light plays a role in our wellbeing. Many of us tend to feel more positive when <a href="https://pubmed.ncbi.nlm.nih.gov/32925966/">spring returns</a>.</p> <p>But for others, big changes in light, such as at the start of spring, can be tough. And for many, bright light at night can be a problem. Here’s what’s going on.</p> <h2>An ancient rhythm of light and mood</h2> <p>In an <a href="https://theconversation.com/how-light-tells-you-when-to-sleep-focus-and-poo-236780">earlier article</a> in our series, we learned that light shining on the back of the eye sends “<a href="https://pubmed.ncbi.nlm.nih.gov/25451984/">timing signals</a>” to the brain and the master clock of the circadian system. This clock coordinates our daily (circadian) rhythms.</p> <p>“Clock genes” also regulate circadian rhythms. These genes control the timing of when many other genes <a href="https://pubmed.ncbi.nlm.nih.gov/31557726/">turn on and off</a> during the 24-hour, light-dark cycle.</p> <p>But how is this all linked with our mood and mental health?</p> <p>Circadian rhythms can be disrupted. This can happen if there are problems with how the body clock develops or functions, or if someone is routinely exposed to bright light at night.</p> <p>When circadian disruption happens, it increases the risk of certain <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental disorders</a>. These include <a href="https://www.sciencedirect.com/science/article/abs/pii/S0149763422000744">bipolar disorder</a> and <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-11-79">atypical depression</a> (a type of depression when someone is extra sleepy and has problems with their energy and metabolism).</p> <h2>Light on the brain</h2> <p>Light may also affect circuits <a href="https://pubmed.ncbi.nlm.nih.gov/35687680/">in the brain</a> that control mood, as <a href="https://pubmed.ncbi.nlm.nih.gov/23151476/">animal studies show</a>.</p> <p>There’s evidence this happens in humans. A brain-imaging study showed exposure to bright light in the daytime while inside the scanner <a href="https://www.cell.com/fulltext/S0960-9822(06)01758-1">changed the activity</a> of a brain region involved in mood and alertness.</p> <p>Another brain-imaging study <a href="https://pubmed.ncbi.nlm.nih.gov/22111663/">found</a> a link between daily exposure to sunlight and how the neurotransmitter (or chemical messenger) serotonin binds to receptors in the brain. We see alterations in serotonin binding in several <a href="https://pubmed.ncbi.nlm.nih.gov/33651238/">mental disorders</a>, including depression.</p> <h2>What happens when the seasons change?</h2> <p>Light can also affect mood and mental health as the seasons change. During autumn and winter, symptoms such as low mood and fatigue can develop. But often, once spring and summer come round, these symptoms go away. This is called “seasonality” or, when severe, “<a href="https://www.aafp.org/pubs/afp/issues/2020/1201/p668.html">seasonal affective disorder</a>”.</p> <p>What is less well known is that for other people, the change to spring and summer (when there is <em>more</em> light) can also come with a change in mood and mental health. Some people experience increases in energy and the drive to be active. This is positive for some but can be seriously destabilising for others. This too is an example of seasonality.</p> <p>Most people <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0239033">aren’t very seasonal</a>. But for those who are, seasonality has a <a href="https://pubmed.ncbi.nlm.nih.gov/8540777/">genetic component</a>. Relatives of people with seasonal affective disorder are more likely to also experience seasonality.</p> <p>Seasonality is also more common in conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/25063960/">bipolar disorder</a>. For many people with such conditions, the shift into shorter day-lengths during winter can trigger a depressive episode.</p> <p>Counterintuitively, the longer day-lengths in spring and summer can also destabilise people with bipolar disorder into an “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10947388/">activated</a>” state where energy and activity are in overdrive, and symptoms are harder to manage. So, seasonality can be serious.</p> <p>Alexis Hutcheon, who experiences seasonality and helped write this article, told us:</p> <blockquote> <p>[…] the season change is like preparing for battle – I never know what’s coming, and I rarely come out unscathed. I’ve experienced both hypomanic and depressive episodes triggered by the season change, but regardless of whether I’m on the ‘up’ or the ‘down’, the one constant is that I can’t sleep. To manage, I try to stick to a strict routine, tweak medication, maximise my exposure to light, and always stay tuned in to those subtle shifts in mood. It’s a time of heightened awareness and trying to stay one step ahead.</p> </blockquote> <h2>So what’s going on in the brain?</h2> <p>One explanation for what’s going on in the brain when mental health fluctuates with the change in seasons relates to the neurotransmitters serotonin and dopamine.</p> <p>Serotonin helps regulate mood and is the target of <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">antidepressants</a>. There is some evidence of seasonal changes in serotonin levels, potentially being lower <a href="https://academic.oup.com/brain/article/139/5/1605/2468755?login=false">in</a> <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(02)11737-5/abstract?cc=y%3D">winter</a>.</p> <p>Dopamine is a neurotransmitter involved in reward, motivation and movement, and is also a target of some <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">antidepressants</a>. Levels of dopamine may also change with the <a href="https://www.nature.com/articles/s41398-023-02365-x">seasons</a>.</p> <p>But the neuroscience of seasonality is a developing area and more research <a href="https://www.nature.com/articles/s41398-023-02365-x">is needed</a> to know what’s going on in the brain.</p> <h2>How about bright light at night?</h2> <p>We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms.</p> <p>This type of circadian rhythm disturbance is associated with higher rates of symptoms <a href="https://www.nature.com/articles/s44220-023-00135-8">including</a> self-harm, depressive and anxiety symptoms, and lower wellbeing. It is also associated with higher rates of <a href="https://pubmed.ncbi.nlm.nih.gov/32639562/">mental disorders</a>, such as major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (or PTSD).</p> <p>Why is this? Bright light at night confuses and destabilises the body clock. It disrupts the rhythmic regulation of mood, cognition, appetite, metabolism and <a href="https://pubmed.ncbi.nlm.nih.gov/38214638/">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">other</a> <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental</a> <a href="https://pubmed.ncbi.nlm.nih.gov/36661342/">processes</a>.</p> <p>But people differ hugely in their <a href="https://www.pnas.org/doi/10.1073/pnas.1901824116">sensitivity to light</a>. While still a hypothesis, people who are most sensitive to light may be the most vulnerable to body clock disturbances caused by bright light at night, which then leads to a higher risk of mental health problems.</p> <h2>Where to from here?</h2> <p>Learning about light will help people better manage their mental health conditions.</p> <p>By encouraging people to better align their lives to the light-dark cycle (to stabilise their body clock) we may also help prevent conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">depression</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">bipolar disorder</a> emerging in the first place.</p> <p>Healthy light behaviours – avoiding light at night and seeking light during the day – are good for everyone. But they might be especially helpful for people <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">at risk</a> of mental health problems. These include people with a family history of mental health problems or people who are <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">night owls</a> (late sleepers and late risers), who are more at risk of body clock disturbances.</p> <hr /> <p><em>Alexis Hutcheon has lived experience of a mental health condition and helped write this article.</em></p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</em><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/231282/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/jacob-crouse-981668"><em>Jacob Crouse</em></a><em>, Research Fellow in Youth Mental Health, Brain and Mind Centre, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/emiliana-tonini-1638957">Emiliana Tonini</a>, Postdoctoral Research Fellow, Brain and Mind Centre, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ian-hickie-961">Ian Hickie</a>, Co-Director, Health and Policy, Brain and Mind Centre, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image </em><em>credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Doctor defies terminal cancer diagnosis with breakthrough therapy

<p>Dr Tina Willits was told she had just 24 months to live after being diagnosed with breast cancer, but against all odds she is now in remission. </p> <p>The mother-of-five's disease was "everywhere" with three golf-ball sized tumors in her breast and cancerous masses in her ribs, spine, lymph nodes and legs.</p> <p>"When my cancer was detected, it was pretty past a stage four diagnosis and I was too far gone for a mastectomy," she told the <em>Daily M</em><em>ail</em>. </p> <p>She was placed on end-of-care chemotherapy and was told to "enjoy the time you have left". </p> <p>That was nearly three years ago. Now, the 53-year-old US mum is in remission thanks to a breakthrough cancer therapy that uses cold gases and the body's own cells to freeze and fight tumors. </p> <p>"I was devastated, but I was also like no, I was not ok with that diagnosis. I felt I had to do something," she recalled.</p> <p>"I was just really determined that I did not want to live my life with this cancer, even if they could stop it progressing, I didn't want that, I just wanted it gone."</p> <p>Dr Willits' cancer was HER2 positive, which account for about 20 percent of all diagnoses, and she had no family history of the disease.</p> <p>She underwent four rounds of chemotherapy before she sought alternative treatment at the Williams Cancer Institute. </p> <p>The institute sent her a list of supplements to begin taking and advised her to avoid sugar, which some researchers believe can help reduce inflammation and slow down the growth of cancer cells. </p> <p>She then underwent a treatment regimen that is not yet fully approved in the US, with cryoablation as the first step. </p> <p>Cryoablation is the process where doctors insert  a small metal probe through the skin and into the tumor, extremely cold gasses are then released directly into the mass to kill its cells.</p> <p>In the second phase of her treatment, she received immunotherapy, where eight drugs were administered directly into her tumor, which doctors say can prompt the immune system to recognise cancer cells as a threat and trigger an immune response. </p> <p>Dr Willits told the Dailymail that she was shocked when she got the results from her six-week scan after the treatment.</p> <p>"There were none, no tumors. They were just completely gone," she said. </p> <p>"All the metastasis (cancerous growths outside the breast) had completely healed, and the cancer in my lymph nodes was no longer there."</p> <p>After the treatment she had another four rounds of chemotherapy, and still undergoes PET scans every six months. </p> <p>So far the cancer has not been detected in her body since the treatment, and will need to wait for five years of clear results before she can be declared cancer free. </p> <p>Dr Williams, the founder of the institute, developed the treatment regimen over several years, and believes it could offer a better way to treat cancer.</p> <p>He is currently running a trial of the treatment in hard-to-treat prostate cancer patients, although he did not reveal how long the study had been going on for or how many rounds of treatment the patients had received. </p> <p>Since going into remission Dr Willits has travelled to Honduras and Colorado, tried mountain biking and is training for a 5k marathon for breast cancer awareness. </p> <p>"I wouldn't appreciate life like this if I had not gone through the cancer," she said. </p> <p>"No one on their deathbed says I wish I had worked more or got that job, you all say I wish I had spent more time with my parents and kids or gone to that place I had always wanted to." </p> <p><em>Images: DailyMail</em></p> <p> </p>

Five reasons why owning a pet is good for us

<p>With more pets than people, Australians have one of the world’s highest pet ownership rates with 62% of us owning at least one pet. And if you’re wondering why we’re so pet mad, research has shown the benefits include companionship, improved mental wellbeing, lower stress and better heart health.</p> <ol> <li><strong>Pets protect us from loneliness</strong></li> </ol> <p>We see our pet as part of the family. Their unconditional (and non-judgemental) love provides us companionship and help to lower stress and anxiety. Interacting with your pet increases feelings of social support and elevates mood. </p> <p>Dog walking increases opportunities for social interaction. When walking outside, fellow dog walkers love to say hello and introduce themselves and their dog to you. Some cafes and restaurants and hotels are dog-friendly venues too. When travelling alone, it’s  wonderful to be able to take your furry companion with you.</p> <ol start="2"> <li><strong>Pets are good for our mental and physical well-being</strong></li> </ol> <p>Pet ownership brings responsibility and the need for skills to know how to best take care of them. These skills will extend to other animals, and other people. Children who have pets develop better social skills when interacting with their friends.</p> <p>Dog owners enjoy lower blood pressure, lower cholesterol levels and less heart disease. While owning a dog is not fully protective, the benefit of all those dog walks are they keep you fitter, healthier and less stressed.</p> <p>If you are unlucky enough to have a heart attack, your long-term survival rate is assisted by having a dog. While interacting with a pet for 10-12 minutes will lower your blood pressure.</p> <p>One of the joys of owning a pet, is the pleasure they provide, and the feeling is mutual. Gazing into the eyes of your beloved pooch, boosts levels of oxytocin our bonding molecule. Our long-standing human-dog relationship was established over 30,000 years ago.</p> <p>Patting or stroking our pets is soothing, especially their silky ears. This is relaxing and how delightful is it when your pet reciprocates with loud purring or offers their tummy for a rub?</p> <ol start="3"> <li><strong>Pets are good for our immune system</strong></li> </ol> <p>You’ve probably heard about your gut microbiome that’s important to keep you healthy. Being a pet owner provides you a healthier microbiome and more robust immune system by promoting more of the beneficial bacteria and lowering the level of harmful, or pathogenic bacteria in our gut.</p> <p>Not only that, stroking your pet raises levels of immunoglobulin A in your body that forms a physical barrier in the gut to protect you against potential invading pathogens.</p> <p>In addition, pregnant mums with a pet in the household are less likely to have infants with childhood allergies, asthma or obesity.</p> <ol start="4"> <li><strong>Pets help us cope better with pain and recovery from illness</strong></li> </ol> <p>Owning a pet has been shown to help manage chronic pain. Pets often sense when their owner isn’t well or in pain and will stay close by, which is very soothing.</p> <p>Watching our pets play and their antics can serve as a useful distraction to our struggles with pain or illness. Having your pet with you (when allowed) in a hospital setting is reassuring and can lift your mood.</p> <p>Animals can help in the work or learning environment. Some workplaces have an office pet policy where you’re allowed to have you pet stay with you while you work. This has been shown to be great for boosting staff morale, collaboration and overall happiness, while keeping work stress lower.</p> <ol start="5"> <li><strong>Pets help us better manage our own self-care</strong></li> </ol> <p>Self-care is always important to stay fit and healthy but isn’t something we always find easy to do. This is where taking responsibility for a pet can help. Teenagers with type one diabetes when given goldfish to care for, did better in monitoring their own blood sugar levels, while having a pet have also been shown to help younger students stay focused and on task, and achieve higher academic results.</p> <p>Pets enrich our lives in so many ways from improved mental well-being to lower stress, elevated mood and greater social support. Whatever type of pet you choose, remember the benefits will work both ways.</p> <p><em><strong>Dr Jenny Brockis is a board-certified lifestyle medicine physician, workplace health and well-being consultant, and author of The Natural Advantage (Major Street Publishing). www.drjennybrockis.com</strong></em></p> <p><em><strong>Image credits: Shutterstock </strong></em></p>

Woman cured of Type 1 diabetes in life-changing clinical trial

<p>Marlaina Goedel was diagnosed with Type 1 diabetes when she was just five-years-old, and not only was the disease controlling her, but it almost cost her life. </p> <p>"I've crashed my car into a brick building before having a diabetic attack while driving," Goedel recalled. </p> <p>Her condition was so extreme that she felt robbed of a normal childhood, telling the <em>Daily Mail </em>that she was in and out of hospital with  life-threatening diabetic ketoacidosis, which causes toxic chemicals to build up in the blood due to a lack of insulin.</p> <p>Now 30-years-old, the Illinois woman no longer needs daily insulin shots and can finally enjoy sugar again thanks to a pioneering stem cell therapy that has cured her of type 1 diabetes. </p> <p>Goedel was one of three Americans who have been cured of their type 1 diabetes thanks to the clinical trial involving an islet cell transplant. </p> <p>It is a one-off infusion that involved transplanting islet cells into her liver to help her body produce insulin on its own. </p> <p>After four weeks, she no longer needed to take insulin. </p> <p>"[My doctor] said, ‘Mark it on your calendar. Today is the day. Stop all insulin,'" Goedel said of the life-changing moment. </p> <p>"I just went quiet and finally said, ‘I’m here. I’m in shock. I’m going to need you to repeat that.’"</p> <p>The trial was being run at the University of Chicago Medicine Transplant Institute. </p> <p>While Islet cell transplants isn't a new procedure, the current anti-rejection medication used can be toxic to the transplanted cells, potentially making it less effective over time. </p> <p>The clinical trial that ran at the university tested out a new antibody called tegoprubart, which was given to Goedel and the two other patients. </p> <p>Tegoprubart is made from lab-made antibodies that trick the immune system into thinking the body made the cells on its own, preventing them from being rejected. </p> <p>The patients were then given islet cells from a deceased donor's pancreas, which were then infused into the patient's small blood vessels in their liver. Those cells then lodged into the blood vessels and started producing insulin. </p> <p>For Goedel the only side effect of the procedure was "feeling like I got punched in the ribs,"  with the procedure lasting just an hour. </p> <p>"The cure is out there," Goedel told the <em>Daily Mail. </em></p> <p>With her new lease on life, Goedel plans to go back to school and go horse riding without worrying about suffering an attack and causing an accident. </p> <p>"It took a while to get used to saying, 'I am cured. I am diabetes free.' It's been very freeing," she said.</p> <p>"No one should have to live with this disease.

The science of the ideal salad dressing

<p><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>Summer means salads. And salads are even more delicious with a good dressing.</p> <p>Most salad dressings are temporarily stable mixtures of oil and water known as emulsions.</p> <p>But how do salad dressing emulsions form? And how can we enhance our emulsions for better salads and more?</p> <h2>Oil and water don’t mix</h2> <p>It’s accepted wisdom that oil and water don’t mix. The water and oil molecules have distinct chemical properties that don’t interact well together.</p> <p>You may have seen this if you’ve attempted to make a salad dressing by shaking together oil and vinegar (which is mostly water), which gives a temporary suspension that quickly separates.</p> <p>There is a large energy cost to breaking apart and mixing the water and oil layers. The secret to blending them together is to add an extra ingredient known as a “surfactant” or emulsifier.</p> <p>The name surfactant is derived from “surface active”. It highlights that these molecules work at the surface or interface to bridge the interactions between the oil and water. This is similar to how <a href="https://theconversation.com/what-is-sodium-lauryl-sulfate-and-is-it-safe-to-use-125129">detergents</a> are able to remove grease from your dishes.</p> <p>Many vinaigrette recipes call for emulsifiers without specifically mentioning their crucial emulsifying role.</p> <p>Key examples are mustard and garlic, which contain “mucilage” – a mix of carbohydrates – that can act as emulsifiers.</p> <p>So if your vinegar/oil salad dressings are separating, make sure you’re adding enough of these ingredients (which also contain <a href="https://theconversation.com/hate-vegetables-you-might-have-super-taster-genes-74428">wonderful flavour chemicals</a>).</p> <p>Commercial salad dressings also contain naturally sourced emulsifying carbohydrates. These will often be listed on the ingredients as generic “vegetable gum” or similar, and you may need to <a href="https://theconversation.com/busting-the-myth-that-all-food-additives-are-bad-a-quick-guide-for-label-readers-82883">read the label</a> and delve a little deeper into the <a href="https://www.foodstandards.gov.au/consumer/additives/additiveoverview/Documents/Food%20Additive%20Code%20Numbers%20%28July%202014%29.pdf">food additive number</a> to find out the source.</p> <p>Researchers have raised questions about <a href="https://theconversation.com/food-additives-and-chronic-disease-risk-what-role-do-emulsifiers-play-38492">synthetic emulsifiers used in processed food</a>, as studies in mice suggest they have health risks. It’s too early to say exactly what this means for humans.</p> <h2>Shake it ‘til you make it</h2> <p>Mixing is key to dispersing oil in water. While shaking a jar is convenient, a whisk or food processor will give a more complete emulsion. The white (or opaque) colour of many emulsions is due to the formation of microdroplets that scatter light.</p> <p>These mechanical mixing methods are even more essential for the formation of so-called “permanent emulsions” such as mayonnaise.</p> <p>Mayonnaise is an emulsion of oil in water, but egg yolk is the key emulsifier. Egg yolks contain long molecules called <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-642-36605-5_28">phospholipids</a> that are able to interact with both the oil layer and the water. Mayonnaise is an impressively stable emulsion, which is why is can be sold in a shelf-stable form.</p> <p>But it isn’t infinitely stable; heating the mayonnaise emulsion will cause it to split. Perhaps you’ve hurriedly prepared a potato salad and added a mayonnaise-based dressing before the potatoes have cooled down?</p> <p>Or toasted a sandwich spread with mayonnaise? (Incidentally, adding mayonnaise to the <em>outside</em> of a toasted sandwich is an excellent path to some <a href="https://theconversation.com/kitchen-science-from-sizzling-brisket-to-fresh-baked-bread-the-chemical-reaction-that-makes-our-favourite-foods-taste-so-good-58577">delicious and crispy chemical reactions</a>.)</p> <p>The heat destabilises the emulsion and the separate oil and water phases will reform. Depending on the mixture, split emulsions may be recovered by adding more emulsifier and re-whisking or re-mixing.</p> <p>Hollandaise sauce is a notoriously difficult emulsion to prepare. The traditional hollandaise method involves whisking egg yolk, water, and lemon juice over a low heat, then slowly adding melted butter with further whisking. Not only can the emulsion split, but you can also overcook the added emulsifying egg yolk.</p> <p>The key to a successful hollandaise emulsion is separating the butter into fine, dispersed droplets, giving a thick and opaque mixture, but without cooking the eggs. Adding the butter too quickly or without sufficient mixing can give a split sauce.</p> <p>Using an <a href="https://www.seriouseats.com/foolproof-2-minute-hollandaise-recipe">immersion blender</a> can help, as can controlling the temperature of the melted butter. You might get a more consistently emulsified sauce with far less strain on your wrists.</p> <h2>You’ve got me feeling emulsions</h2> <p>Emulsions are used in many more places than salads and sauces. Most medicated creams, cosmetics and lotions are emulsions of oils and water, which is why they look white.</p> <p>Gardeners might be familiar with a mixture known as “<a href="https://www.abc.net.au/gardening/how-to/horticultural-oils/9428876">white oil</a>” – a mixture of vegetable oil and detergent. This brew, when diluted in water, is an inexpensive, effective, yet mild insecticide. Commercial versions often contain other pesticides, so make sure you read the label.</p> <p>Modern <a href="https://www.acs.org/education/whatischemistry/landmarks/acrylicemulsion.html">acrylic paints use emulsions</a> for both their manufacturing and application. The emulsions suspend the paint polymers in a water base.</p> <p>The water from the paint evaporates, leaving a film of paint polymers that can’t be re-dispersed into water. This clever chemical trick has saved huge quantities of oil-derived solvents from being used, <a href="https://theconversation.com/why-solvents-can-affect-brain-health-even-at-low-levels-of-exposure-98081">inhaled</a>, and emitted into the environment from traditional oil-based paints.</p> <p>Modern vaccines use <a href="https://theconversation.com/adjuvants-the-unsung-heroes-of-vaccines-156548">emulsions to increase the immune systems response</a>. Other common emulsions are inks, <a href="https://theconversation.com/how-does-ice-cream-work-a-chemist-explains-why-you-cant-just-freeze-cream-and-expect-results-205038">ice cream</a>, margarine and hair products, to name just a few.</p> <p>So next time you’re making a salad, check your emulsions. Opposites don’t attract, but mixing them with the right chemistry can give a delicious result.<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/216159/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</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.

Nearly 200 chemicals linked to cancer found in everyday food packaging

<p>A new study has uncovered the alarming amount of potential carcinogens in food packaging and plastic tableware. </p> <p>Researchers from the Food Packaging Forum found that nearly 200 chemicals linked to breast cancer are being used in food packaging, with dozens of these carcinogens able to find their way into the body. </p> <p>“There is strong evidence that 76 known or potential breast carcinogens from food contact materials recently purchased all over the world can be found in people,” study co-author Jane Muncke said.</p> <p>“Getting rid of these known or suspected carcinogens in our food supply is a huge opportunity for cancer prevention.”</p> <p>Muncke is managing director and chief scientific officer at the Food Packaging Forum, a non-profit foundation based in Zurich, Switzerland focusing on science communication and research. </p> <p>The study, published last month in the journal Frontiers In Toxicology, compared a list of potential breast carcinogens to a list of chemicals that have been found in food contact materials to find out which of the potential carcinogens could be getting into people's diets. </p> <p>Of the 189 potential mammary carcinogens in food contact materials, with 143 of these found in plastics and 89 found in paper or cardboard. </p> <p>Of the recently detected chemicals found in food packaging, 40 have already been classified as hazardous by regulatory agencies around the world. </p> <p>Another research scientist, Jenny Kay, from Silent Spring Institute an organisation focused on the link between chemicals, women's health, and breast cancer said: “So many of these chemicals have already been classified as human health hazards, yet they are still allowed to be used in food contact materials thus allowing them to migrate into the food we eat." </p> <p>Early-onset breast cancer rates in women younger than 50 have been increasing, and experts said the trend cannot be explained by genetics alone. </p> <p>“Many of the mammary carcinogens are hormone disruptors, too, and many of the chemicals on our list can also damage DNA," Kay said. </p> <p>“Consumers should not have to keep track of all of the scientific literature on what chemicals to avoid. It should be on regulators to recognise the danger and take action.”</p> <p>The Consumer Brands Association, which represents the consumer products industry, said its members adhered to the US Food and Drug Administration’s evidence-based safety standards.</p> <p>“Packaging exists to protect and keep food safe for consumption,” the association’s senior vice president of product policy and federal affairs Sarah Gallo told <em>CNN</em>. </p> <p>“The FDA reviews and approves food contact substances through their science and risk-based system before they go to market.</p> <p>“The agency’s post-market review also provides continuous safety analysis and regulation of the approved substances.”</p> <p><em>Image: Shutterstock</em></p> <p> </p>

Are cats good for our health?

Still, living with cats is not without risks.</p> <h2>Part of the family</h2> <p>You may have heard cats don’t have owners, they have “staff”. In fact, multiple studies show the humans who live with them feel more like beloved relatives.</p> <p>In a <a href="https://www.mdpi.com/1660-4601/19/1/193">study</a> of 1,800 Dutch cat owners, half said their cat was family. One in three viewed their cat as a child or best friend and found them loyal, supportive and empathetic.</p> <p>Another US study developed a “<a href="https://www.frontiersin.org/journals/veterinary-science/articles/10.3389/fvets.2021.812922/full">family bondedness</a>” scale and found cats were just as important a part of families as dogs.</p> <p>Many cats would choose <a href="https://www.sciencedirect.com/science/article/abs/pii/S0376635716303424">human interaction</a> over food or toys. And <a href="https://link.springer.com/article/10.1007/s10071-022-01674-w">they can distinguish</a> when we are talking to them (rather than another human).</p> <p>In fact we’ve adapted to each other. Cats are <a href="https://www.nature.com/articles/s41598-020-73426-0">more likely</a> to approach human strangers who first give a “kitty kiss” – narrowing your eyes and blinking slowly. And research suggests cats have developed <a href="https://theconversation.com/why-cats-meow-at-humans-more-than-each-other-232865">specific meows</a> that tune into our nurturing instincts.</p> <p>What does this close relationship mean for health outcomes?</p> <h2>A sense of purpose</h2> <p>Owning a pet is associated with <a href="https://link.springer.com/article/10.1007/s00127-022-02332-9">less social isolation</a>.

It found people whose relationship with their cat was co-dependent or like a friend had a higher emotional connection to their pet.</p> <h2>Links to heart health</h2> <p>People who own – or have owned – a cat have a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3317329/">lower risk</a> of dying from cardiovascular diseases such as stroke or heart disease.

This means while people with cats have lower risk of dying from cardiovascular diseases, we can’t say for sure cats are the cause.</p> <p>Cat ownership has also been associated with some positive changes in the <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0253133">gut microbiota</a>, especially in women, such as improved blood glucose control and reduced inflammation.</p> <h2>Helping mental health</h2> <p>Having cat or dog is also associated with <a href="https://www.tandfonline.com/doi/full/10.1080/08927936.2023.2182029">higher psychological well-being</a>.

My cat helps me to relax when I’m dealing with my anxiety, depression or when I wake during the night from the frequent nightmares I have. My cat isn’t just a pet to me, my cat is a part of me, my cat is part of my family.</p> </blockquote> <p>It may be that veterans were more attached to their cats because they had worse mental health – and relied on their cats more for comfort – rather than the other way around.</p> <h2>Mental health downsides</h2> <p>It is possible being attached to your cat has downsides.

Baywatch star dies after lengthy health battle

<p><em>Baywatch</em> actor Michael Newman has died at the age of 68 after a lengthy battle with Parkinson's disease. </p> <p>The actor, who played  lifeguard Mike “Newmie” Newman on <em>Baywatch</em> in the 1990s, was diagnosed with the neurological condition 18 years ago, and died “from heart complications” on Sunday evening “surrounded by his family and friends.”</p> <p>His death was confirmed Tuesday by Newman’s close friend, Matt Felker, who recently directed the Hulu docu-series about <em>Baywatch</em>.</p> <p>“I got to see Mike the last time he was conscious and he looked [at] me and in typical Mike fashion said, ‘You’re just in time,’” Felker told <a href="https://people.com/" target="_blank" rel="noopener"><em>People</em>.</a></p> <p>Newman was the only <em>Baywatch</em> cast member who was a real-life lifeguard. He appeared on 150 episodes of the show, the most of anyone except David Hasselhoff.</p> <p>While starring on Baywatch, he continued to work as a full-time firefighter and returned to the job after the show ended in 2001, until he retired after 25 years.</p> <p>Newman was 50 when he was diagnosed with Parkinson’s in 2006, as he spoke about living with the disease just months ago. </p> <p>“This terminal disease has allowed me a lot of thinking time, which I maybe didn’t want, but it’s brought me wisdom,” Newman told <em>People</em> in August.</p> <p>“My body has changed so slowly that I hardly notice it, yet I am constantly reminded that Parkinson’s has now become the centre of my life,” he added.</p> <p>“I am cherishing the days that I get to be on this earth with family and friends,” he went on. “I’m taking life seriously.”</p> <p>Newman spent the final years of his life raising money with the Michael J. Fox Foundation to help find a cure for Parkinson’s.</p> <p>The late star is survived by his wife of 36 years, Sarah, their children Chris and Emily, and their 1-year-old granddaughter, Charlie.</p> <p><em>Image credits: SplashNews.com/Shutterstock Editorial </em></p>

Serena Williams “mortified” by health scare

<p>Serena Williams has undergone a procedure in hospital to remove a brachial cyst in her neck. </p> <p>The tennis legend documented her health scare on TikTok, sharing how she ended up in surgery after doctors originally told her not to worry about it. </p> <p>“A lot has been happening and I had surgery recently where I had to take some yucky medicine that I hated so much,” she said in a video. </p> <p>“One day back in May, I found this big mass on my neck. I was mortified by it and I got tests done — everything you can imagine. Everything was negative."</p> <p>“Turns out I have what’s called a cyst, a brachial cyst, to be exact."</p> <p>“(Doctors) said I don’t need to get it removed if I don’t want. So, I did not get it (removed) but it kept growing."</p> <p>“I decided to get more tests and, three tests and one biopsy later, everything was still negative, but doctors advised I get it removed as soon as possible because it was the size of a small grapefruit and it could get infected, or worse, leak.”</p> <p>Williams then shared vision of the procedure she had to undergo to have it removed.</p> <p>“So, I ended up having to get it removed. It was so big, it was the size of a grapefruit, and it kind of hurt at coming out,” she went on.</p> <p>“Obviously I went under (general anesthetic) for it, but they had to put a drain in it because it was so much."</p> <p>“But everything worked out and I feel really happy to have worked with some great doctors."</p> <p>“A little scared here but excited to move on to the next steps of healing and doing well.”</p> <p>The 43-year-old mother-of-two is still recovering from the operation, saying, “I am feeling so grateful, and fortunate everything worked out, and most of all I’m healthy."</p> <p><em>Image credits: TikTok / Andrew Schwartz / Shutterstock Editorial</em></p>

The science of happier dogs: 5 tips to help your canine friends live their best life

<p><em><a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>When you hear about “science focused on how dogs can live their best lives with us” it sounds like an imaginary job made up by a child. However, the field of <a href="https://www.rnz.co.nz/podcast/ourchangingworld?share=2ec8e0ad-5008-4b2d-ae2e-a288e2a77f50">animal welfare science is real</a> and influential.</p> <p>As our most popular animal companion and coworker, dogs are very deserving of scientific attention. In recent years we’ve learned more about <a href="https://theconversation.com/dogs-can-get-dementia-but-lots-of-walks-may-lower-the-risk-189297">how dogs are similar to people</a>, but also how they are distinctly themselves.</p> <p>We often think about how dogs help us – as companions, <a href="https://theconversation.com/meet-moss-the-detection-dog-helping-tassie-devils-find-love-142909">working as detectors</a>, and keeping us <a href="https://theconversation.com/is-owning-a-dog-good-for-your-health-238888">safe and healthy</a>. Dog-centric science helps us <a href="https://www.frontiersin.org/journals/veterinary-science/articles/10.3389/fvets.2021.666898/full">think about the world from a four-paw perspective</a> and apply this new knowledge so dogs can enjoy a good life.</p> <p>Here are five tips to keep the tails in your life wagging happily.</p> <h2>1. Let dogs sniff</h2> <p>Sniffing <a href="https://www.psychologytoday.com/intl/blog/animal-emotions/201902/allowing-dogs-sniff-helps-them-think-positively">makes dogs happier</a>. We tend to forget they live in a smell-based world because we’re so visual. Often taking the dog for a walk is our daily physical activity but we should remember it could be our dogs’ only time out of the home environment.</p> <p>Letting them have a really good sniff of that tree or post is full of satisfying information for them. It’s their nose’s equivalent of us standing at the top of a mountain and enjoying a rich, colour-soaked, sunset view.</p> <h2>2. Give dogs agency</h2> <p>Agency is a <a href="https://www.frontiersin.org/journals/veterinary-science/articles/10.3389/fvets.2023.1284869/full">hot topic in animal welfare science</a> right now. For people who lived through the frustration of strict lockdowns in the early years of COVID, it’s easy to remember how not being able to go where we wanted, or see who we wanted, when we wanted, impacted our mental health.</p> <p>We’ve now learned that <a href="https://www.frontiersin.org/journals/veterinary-science/articles/10.3389/fvets.2023.1250251/full">giving animals choice and control</a> in their lives is important for their mental wellbeing too. We can help our dogs enjoy better welfare by creating more choices and offering them control to exercise their agency.</p> <p>This might be installing a doggy door so they can go outside or inside when they like. It could be letting them decide which sniffy path to take through your local park. Perhaps it’s choosing which three toys to play with that day from a larger collection that gets rotated around. Maybe it’s putting an old blanket down in a new location where you’ve noticed the sun hits the floor for them to relax on.</p> <p>Providing choices doesn’t have to be complicated or expensive.</p> <h2>3. Recognise all dogs are individuals</h2> <p>People commonly ascribe certain personality traits to certain dog breeds. But just like us, dogs have their own personalities <a href="https://scitechdaily.com/food-vs-toys-scientists-reveal-what-dogs-truly-prefer/">and preferences</a>. Not all dogs are going to like the same things and a new dog we live with may be completely different to the last one.</p> <p>One dog might like to go to the dog park and run around with other dogs at high speed for an hour, while another dog would much rather hang out with you chewing on something in the garden.</p> <p>We can see as much <a href="https://www.science.org/content/article/your-dog-s-breed-doesn-t-determine-its-personality-study-suggests">behavioural variation within breeds as we do between them</a>. Being prepared to meet dogs where they are, as individuals, is important to their welfare.</p> <p>As well as noticing what dogs like to do as individuals, it’s important not to force dogs into situations they don’t enjoy. <a href="https://www.rspca.org.uk/adviceandwelfare/pets/dogs/behaviour/understanding">Pay attention to behaviour</a> that indicates dogs aren’t comfortable, such as looking away, licking their lips or yawning.</p> <h2>4. Respect dogs’ choice to opt out</h2> <p>Even in our homes, we can provide options if our dogs don’t want to share in every activity with us. Having a quiet place that dogs can retreat to is really important in enabling them to opt out if they want to.</p> <p>If you’re watching television loudly, it may be too much for <a href="https://www.psychologytoday.com/au/blog/canine-corner/202407/how-good-is-a-dogs-hearing-compared-to-humans">their sensitive ears</a>. Ensure a door is open to another room so they can retreat. Some dogs might feel overwhelmed when visitors come over; giving them somewhere safe and quiet to go rather than forcing an interaction will help them cope.</p> <p>Dogs can be terrific role models for children when teaching empathy. We can demonstrate consent by letting dogs approach us for pats and depart when they want. Like seeing exotic animals perform in circuses, dressing up dogs for our own entertainment seems to have had its day. If you asked most dogs, they don’t want to wear costumes or be part of your Halloween adventures.</p> <h2>5. Opportunities for off-lead activity – safely.</h2> <p>When dogs are allowed to run off-lead, they use space differently. They tend to explore more widely and go faster than they do when walking with us on-lead. This offers them important and fun physical activity to keep them fit and healthy.</p> <figure><iframe src="https://www.youtube.com/embed/2AchEFiDwA8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Demonstrating how dogs walk differently when on- and off-lead.</span></figcaption></figure> <p>A recent exploration of <a href="https://pursuit.unimelb.edu.au/articles/we-checked-if-melbourne-really-is-a-dog-friendly-city">how liveable cities are for dogs</a> mapped all the designated areas for dogs to run off-leash. Doggy density ranged from one dog for every six people to one dog for every 30 people, depending on where you live.</p> <p>It also considered how access to these areas related to the annual registration fees for dogs in each government area compared, with surprising differences noted across greater Melbourne. We noted fees varied between A$37 and $84, and these didn’t relate to how many off-lead areas you could access.</p> <p>For dog-loving nations, such as Australia, helping our canine friends live their best life feels good. <a href="https://www.rnz.co.nz/national/programmes/afternoons/audio/2018957756/our-changing-world-the-science-behind-dog-welfare">Science that comes from a four-paw perspective</a> can help us reconsider our everyday interactions with dogs and influence positive changes so we can live well, together.<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/236952/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, Research Fellow, Animal Welfare Science Centre, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</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.

King Charles' special tribute to Holocaust survivor

<p>King Charles has paid tribute to Holocaust survivor Lily Ebert, who has died aged 100. </p> <p>The Hungarian-born British writer died peacefully at home in north London. She was the eldest of six children and was freed from Auschwitz at the age of 20, almost 80 years ago, as her mother and two younger siblings were killed in the gas chambers.</p> <p>She migrated to the UK in 1967 with her husband and began educating the world about the horrors of the Holocaust. </p> <p>Since then, her story and resilience has touched millions worldwide, including King Charles, who met her in 2015 when she joined him to light one of six remembrance candles in London for the Holocaust Memorial Day Trust. </p> <p>Last year, he made her an MBE (Most Excellent Order of the British Empire) in recognition of her services to Holocaust education. </p> <p>In a statement released by Buckingham Palace, the monarch said  "it was with the greatest sadness" that he had heard of her death.</p> <p>"As a survivor of the unmentionable horrors of the Holocaust, I am so proud that she later found a home in Britain where she continued to tell the world of the horrendous atrocities she had witnessed, as a permanent reminder for our generation – and, indeed, for future generations – of the depths of depravity and evil to which humankind can fall, when reason, compassion and truth are abandoned," he said.</p> <p>"Alongside other Holocaust survivors, she became an integral part of the fabric of our nation; her extraordinary resilience and courage an example to us all, which will never be forgotten."</p> <p>In 2021, Charles, who was the Prince of Wales described how he had been personally inspired throughout his own life by the stories of survivors and their bravery and personal sacrifice. </p> <p>At the unveiling of the Queen's Gallery in London, Ebert told him:  "Meeting you, it is for everyone who lost their lives." </p> <p>To which the King replied:  "But it is a greater privilege for me."</p> <p>Ebert's great-grandson Dov Forman, who helped co-write her book<em> How I Survived Auschwitz and Found the Strength to Live, </em>paid tribute to the family's "beloved matriarch", known as Safta on social media. </p> <p>"Over the years, Safta's story touched hundreds of millions worldwide, reminding us of the resilience of the human spirit and the dangers of unchecked hatred," he began.</p> <p>"She taught us the power of tolerance and faith, the importance of speaking out, and the need to stand against prejudice.</p> <p>"Safta was the queen of our large, loving family. With a surviving daughter and son – remembering a daughter who pre-deceased her – 10 grandchildren, 38 great-grandchildren and one great-great-grandchild, her legacy lives on in each of us.</p> <p>"She rebuilt her life with faith and love, never asking, 'Why me?'. Instead, she focused on what could be rebuilt from the ashes, and her positivity continues to guide us through these difficult times.</p> <p>"As we mourn our beloved Mummy, Safta, we also celebrate her extraordinary life.</p> <p>"A light that shone so brightly has gone dark. She was our hero, and her absence leaves an unimaginable void in our lives."</p> <p><em>Images: </em><em>Arthur Edwards/WPA Pool/ Shutterstock Editorial</em></p> <p> </p>
