What causes food cravings? And what can we do about them?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/gabrielle-weidemann-91497">Gabrielle Weidemann</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/justin-mahlberg-1634725">Justin Mahlberg</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Many of us try to eat more fruits and vegetables and less ultra-processed food. But why is sticking to your goals so hard? High-fat, sugar-rich and salty foods are simply so enjoyable to eat. And it’s not just you – we’ve evolved that way. These foods <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5928395/">activate</a> the brain’s reward system because in the past they were <a href="https://doi.org/10.1037/a0030684">rare</a>. Now, they’re all around us. In wealthy modern societies we are bombarded by <a href="https://theconversation.com/junk-food-is-promoted-online-to-appeal-to-kids-and-target-young-men-our-study-shows-234285">advertising</a> which intentionally reminds us about the sight, smell and taste of calorie-dense foods. And in response to these powerful cues, our brains respond just as they’re designed to, triggering <a href="https://doi.org/10.1111/obr.12354">an intense urge</a> to eat them. Here’s how food cravings work and what you can do if you find yourself hunting for sweet or salty foods. <h2>What causes cravings?</h2> A food craving is an intense desire or urge to eat something, <a href="https://pubmed.ncbi.nlm.nih.gov/15589112/">often focused on a particular food</a>. We are programmed to learn how good a food tastes and smells and where we can find it again, especially if it’s high in fat, sugar or salt. Something that <a href="https://doi.org/10.1111/obr.12354">reminds us</a> of enjoying a certain food, such as an eye-catching ad or delicious smell, can cause us to <a href="https://doi.org/10.1111/obr.12354">crave it</a>. The cue triggers a physical response, increasing saliva production and gastric activity. These responses are relatively automatic and difficult to control. <h2>What else influences our choices?</h2> While the effect of cues on our physical response is relatively automatic, what we do next is influenced by <a href="https://journals.sagepub.com/doi/pdf/10.1177/1090198107303308">complex</a> factors. Whether or not you eat the food might depend on things like cost, whether it’s easily available, and if eating it would align with your health goals. But it’s usually hard to keep healthy eating in mind. This is because we tend to prioritise a more immediate reward, like the <a href="https://doi.org/10.1016/j.physbeh.2010.04.029">pleasure of eating</a>, over one that’s delayed or abstract – including health goals that will make us feel good in the long term. <a href="https://doi.org/10.1016/S0022-3999(00)00076-3">Stress</a> can also make us eat more. When hungry, we <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8656885/">choose larger portions</a>, underestimate calories and find eating more <a href="https://www.sciencedirect.com/science/article/pii/S0195666315000793">rewarding</a>. <h2>Looking for something salty or sweet</h2> So what if a cue prompts us to look for a certain food, but it’s not available? <a href="https://doi.org/10.1016/j.appet.2014.04.005">Previous research</a> suggested you would then look for anything that makes you feel good. So if you saw someone eating a doughnut but there were none around, you might eat chips or even drink alcohol. But our <a href="https://doi.org/10.1016/j.appet.2024.107640">new research</a> has confirmed something you probably knew: it’s more specific than that. If an ad for chips makes you look for food, it’s likely a slice of cake won’t cut it – you’ll be looking for something salty. Cues in our environment don’t just make us crave food generally, they prompt us to look for certain food “categories”, such as salty, sweet or creamy. <h2>Food cues and mindless eating</h2> Your <a href="https://core.ac.uk/download/pdf/161283824.pdf">eating history</a> and <a href="https://doi.org/10.1002/eat.24179">genetics</a> can also make it harder to suppress food cravings. But don’t beat yourself up – relying on willpower alone is <a href="https://doi.org/10.1016/j.appet.2015.01.004">hard</a> for almost everyone. Food cues are so powerful they can prompt us to <a href="https://doi.org/10.1177/0956797613484043">seek</a> out a certain food, even if we’re not overcome by a particularly <a href="https://doi.org/10.1177/0956797613484043">strong urge</a> to eat it. The effect is more intense if the food is easily available. This helps explain why we can eat an entire large bag of chips that’s in front of us, even though our pleasure decreases as we <a href="https://doi.org/10.1016/0031-9384(81)90310-3">eat</a>. Sometimes we use finishing the packet as the signal to stop <a href="https://doi.org/10.1016/j.physbeh.2015.03.025">eating</a> rather than hunger or desire. <h2>Is there anything I can do to resist cravings?</h2> We largely don’t have control over cues in our environment and the cravings they trigger. But there are some ways you can try and control the situations you make food choices in. <ul> <li> Acknowledge your craving and think about a healthier way to satisfy it. For example, if you’re craving chips, could you have lightly-salted nuts instead? If you want something sweet, you could try fruit. </li> <li> Avoid shopping when you’re hungry, and make a list beforehand. Making the most of supermarket “click and collect” or delivery options can also help avoid ads and impulse buys in the aisle. </li> <li> At home, have fruit and vegetables easily available – and easy to see. Also have other nutrient dense, fibre-rich and unprocessed foods on hand such as nuts or plain yoghurt. If you can, remove high-fat, sugar-rich and salty foods from your environment. </li> <li> Make sure your goals for eating are <a href="https://www.aafp.org/pubs/fpm/issues/2018/0300/p31.html">SMART</a>. This means they are specific, measurable, achievable, relevant and time-bound. </li> <li> Be kind to yourself. Don’t beat yourself up if you eat something that doesn’t meet your health goals. Just keep on trying.<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/237035/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/gabrielle-weidemann-91497">Gabrielle Weidemann</a>, Associate Professor in Psychological Science, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/justin-mahlberg-1634725">Justin Mahlberg</a>, Research Fellow, Pyschology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do mobile phones cause brain cancer? Science makes definitive call

The question of whether mobile phones - specifically the electromagnetic radiation or radio waves emitted by these devices - cause cancer has been debated and researched for a long time, and now scientists have made a definitive call. A new comprehensive review commissioned by the World Health Organization has found that mobile phones are NOT linked to brain and head cancers. The systematic review, led by the Australian Radiation Protection and Nuclear Safety Agency (Arpansa), examined over 5,000 studies, which included 63 observational studies on humans published between 1994 and 2022 and is "the most comprehensive review to date" according to review lead author, associate prof Ken Karipidis. “We concluded the evidence does not show a link between mobile phones and brain cancer or other head and neck cancers," he said. The review, which was published on Wednesday, focused on cancers of the nervous system, salivary gland and brain tumours. They found no overall association between mobile phone use and cancer, even if people have used it for a long time (over 10 years) or spend a lot of time on their phones. “I’m quite confident with our conclusion. And what makes us quite confident is … even though mobile phone use has skyrocketed, brain tumour rates have remained stable,” Karipidis continued. Despite emitting electromagnetic radiation, also known as radio waves, the exposure is relatively low. Karipidis said people hear the word radiation and assume it is similar to nuclear radiation, “and because we use a mobile phone close to the head when we’re making calls, there is a lot of concern.” He clarified that “radiation is basically energy that travels from one point to another. There are many different types, for example, ultraviolet radiation from the sun." “We’re always exposed to low-level radio waves in the everyday environment.” While exposure from mobile phones is still low, it is much higher than exposure from any other wireless technology sources since they are used close to the head, Karipidis said. The association between mobile phones and cancers came about from early studies comparing differences between those with and without brain tumours and asking about their exposure history. According to Karipidis, who is also the vice-chair of the International Commission on Non-Ionizing Radiation Protection, the results from these kind of studies tend to be biased, as the group with the tumour tend to overreport their exposure. Based on these early studies WHO’s International Agency for Research on Cancer (IARC) designated radio-frequency fields like those from mobile phones as a possible cancer risk, but Karipidis said "this classification doesn’t mean all that much”. This is because the IARC has different classifications of cancer risk, with some substances classified as a “definite” carcinogen (such as smoking), and others as “probable” or “possible” carcinogens. Tim Driscoll, a professor at the University of Sydney and chair of the Australian Cancer Council’s occupational and environmental cancers committee, also backed the systematic review. “I think people should feel reassured by this study … but it’s worthwhile just remembering that the studies aren’t perfect, but the weight of evidence certainly is that mobile phones should be considered safe to use in terms of any concerns about increased risk of cancer,” Driscoll said.

The important cause that brought Ally Langdon to tears

Ally Langdon teared up on Thursday's episode of A Current Affair during a heartfelt segment on organ donation. The host was discussing Jersey Day with Michael Gremmo, a father who had lost his 13-year-old son Nathan after he was critically injured when crossing the road in 2014. Nathan went on to become an organ donor - a decision that saved six lives, including a baby. Now his father is honouring his son's legacy by encouraging others to have the important conversation about organ and tissue donation with loved ones. "Nathan, as most organ donors are, are healthy, fit, young people and their lives are just taken from them," Michael said. "Dealing with Nathan not coming back, that's the hardest, but we wanted something positive to come out of a horrible situation." The A Current Affair host fought back tears as she recalled how her own sister's life was saved after receiving a pancreas-kidney transplant in 2014. "My sister is alive because of someone as special as Nathan and there’s not a day goes by that we don’t as a family think about them and think about their grief." “Thank you,” Langtold told Michael tearfully. Michael replied: “Nathan hasn’t died in vain. He’s given life. And you’ve got your sister here because of a generous donor. And it’s not just the donor, it’s their family too. When you’re in that situation it’s hard.” Langdon then encouraged viewers to "have the conversation" about organ donation with loved ones of all ages. "Tell your family your wishes, because the final decision is theirs," she said. Michael said despite his son's young age, Nathan had talked about organ donation and expressed his desire to be one before his passing. “It’s not a conversation you usually have or want to have with young children,” Michael said. "Nathan had actually had a conversation with us, he watched a program on TV and it was about organ recipients ... he sat us down and spoke to us about that. "And yeah, we just talked about what a wonderful gift that would be." Jersey Day falls on Friday August 30, during which students and employees at schools and workplaces across the country are encouraged to wear their favourite jersey and have the important conversation about organ donation with their loved ones. "It's not just the lives of the organ recipient [you save], it's the families behind that too that, you know, you don't realise how many people are affected," Michael said. "I suppose that's why Jersey Day is so special as it's about awareness and getting it out there and having that important conversation."

"Sexy Santas" cause outrage at Seven staff meeting

Channel 7 has come under fire after footage of a routine staff meeting featured scantily clad dancers dressed as Santa. The meeting of Seven Network parent company Seven West Media in Perth was held on Friday to introduce a series of new hires and appointments, while deputy news director Ray Kuka also discussed upcoming programming for the rest of the year. As part of the announcement, Kuka spoke of Perth’s annual Christmas Pageant on December 7th, when Mariah Carey’s All I Want for Christmas started playing and a group of female dancers wearing Santa hats and short red dresses appeared and started dancing. Female staff who watched on were said to have been "dumbstruck and horrified" by the bizarre scene, with <a href="https://www.afr.com/rear-window/stokes-woke-regime-comes-with-sexy-surprise-20240825-p5k54h" target="_blank" rel="noopener">The Australian Financial Review</a> claiming many likened the dancers to "sl*tty elves". A photo of the event was shared online and drew heavy criticism, as one worker shared that the performance prompted a mass walk out of outraged staffers. “OMG – if they thought that was even slightly appropriate given everything we’ve found out about them, the cultural makeup of that organisation is badly broken,” one person wrote online. “That will help fix the culture issues which have been uncovered.” A spokesman for Seven West Media defended the dancers, explaining that they were part of the Christmas Pageant, which is a “Perth institution”. The footage of the meeting comes as Seven faces a series of internal challenges as they fight allegations of being a "toxic" workplace. Ryan Stokes, the managing director of Seven Group Holdings Ltd, recently called inappropriate behaviour in media an "industry-wide problem". Stokes said it was "disappointing that there is a perception [that] inappropriate behaviour" was tolerated at Seven because "we don't tolerate any inappropriate behaviour".

After an illustrious cricket career in the UK, Thorpe died on August 5th at just 55 years old, leaving behind his wife and four children. Thorpe had previously been hospitalised in May 2022 following a suicide attempt, but made a full recovery. His wife Amanda has spoken out about her husband's mental illness, sharing how he had been suffering for many years. “Despite having a wife and two daughters whom he loved and who loved him, he did not get better,” Amanda told The Times. “He was so unwell in recent times and he really did believe that we would be better off without him.” She added: “We are devastated that he acted on that and took his own life.” Amanda said Graham had suffered from major depression and anxiety “for a couple of years”, explaining, “Despite glimpses of hope and of the old Graham, he continued to suffer from depression and anxiety, which at times got very severe." “We supported him as a family and he tried many, many treatments but unfortunately none of them really seemed to work." “Graham was renowned as someone who was very mentally strong on the field and he was in good physical health. But mental illness is a real disease and can affect anyone.” Following his sudden death, the England and Wales Cricket Board released a statement that said, “It is with great sadness that we share the news that Graham Thorpe, MBE, has passed away." “There seem to be no appropriate words to describe the deep shock we feel at Graham’s death." “More than one of England’s finest-ever batters, he was a beloved member of the cricket family and revered by fans all over the world."

Cause of death revealed after eight-year-old dies mid-flight

The cause of death of an eight-year-old girl who died suddenly mid-flight has been revealed. Sydney Weston was travelling with her family from their home state of Missouri to Chicago on June 13th when she suddenly fell ill on the flight and died. Now, according to Peoria County Coroner Jamie Harwood, Sydney was suffering from at least five different illnesses at the time of her death. The eight-year-old reportedly died from complications of chronic primary adrenalitis coupled with several infections, including enterovirus and strep, as well as inflammation of the small intestines known as duodenitis and the thyroid gland inflammation commonly known as thyroiditis. Harwood found that the long list of conditions suggests Sydney may have suffered from an autoimmune disorder which left her body attacking its own healthy cells and harming organ operation. Sydney suffered a medical emergency onboard the flight, causing the plane to divert to Peoria, Illinois, for an emergency landing, but Sydney died after being rushed to a nearby hospital. Results from a previously released preliminary autopsy were inconclusive but found that her body showed no signs of abuse, neglect or foul play. At the time of her sudden and tragic death, Sydney was just a week away from celebrating her ninth birthday. “She will forever be remembered for the happiness she brought to every single person she encountered. Our hearts are heavy. She was our baby girl and we celebrate her beautiful life,” her obituary read. Image credits: Instagram

Clint Eastwood's partner's cause of death revealed

The cause of death of Clint Eastwood's partner has been revealed, just days after the actor addressed her tragic passing. Christina Sandera, Eastwood's partner of 10 years, died suddenly on July 18th at just 61 years of age. Now, a representative from the Monterey County Health Department confirmed to <a href="https://nypost.com/2024/07/23/entertainment/clint-eastwoods-partner-christina-sanderas-cause-of-death-revealed/" target="_blank" rel="noopener">The New York Post</a> that Sandera died of a heart attack. The death certificate listed her immediate cause as cardiac arrhythmia, which is an abnormality in the timing or pattern of the heartbeat. Atherosclerotic coronary artery disease was also outlined as an additional condition that led to Sandera’s death. Eastwood addressed the passing of his partner after the Hollywood Reporter confirmed her death, with the actor writing, “Christina was a lovely, caring woman, and I will miss her very much.” The pair met when Sandera worked as a hostess at a hotel and restaurant owned by the actor in California, before they started dating in 2014. The couple largely kept their romance out of the public eye with Sandera only attended a handful of events with the Hollywood icon during their 10-year relationship. The couple, who never married, walked their last red carpet together in November 2019 at AFI Fest in Hollywood. One of Eastwood's children from a previous marriage Morgan, 27, paid tribute to her father’s longtime love on Sunday by sharing a photo of herself, her father and Eastwood and her wedding, writing, “A devastating loss for our whole family.

Motive and cause of death revealed after six found dead in luxury hotel

Six people found dead in a luxury hotel room in central Bangkok are believed to have died due to poisoning, according to Thai police. Authorities shared photo of the teacups found in the room on the fifth floor of the hotel, revealing they found traces of cyanide in the cups. The bodies of two American and four Vietnamese nationals were found by hotel staff on Tuesday evening, after staff entered the room to inform them it was past check out time. The group, made up of three men and three women aged between 37 and 56, likely drank from tea and coffee cups laced with cyanide following a dispute linked to bad investments, Thai police said on Wednesday. Photos of the crime scene released by authorities show a lack of struggle and violence, instead showing bodies scattered around the room among plates of untouched food, and two thermos flasks and cups. Initial examinations revealed the presence of cyanide in six cups, according to police. “The mouths and nails on all the bodies turned purple, showing a lack of air could be a joint reason of the cause of the death,” forensic doctor Kornkiat Vongpaisarnsin, told a press conference at the Chulalongkorn University. “We presume they all died from cyanide which causes a lack of air in some organs,” he added. Authorities initially said they were searching for a seventh person who was part of the hotel booking, but on Wednesday they dismissed this line of inquiry, saying they believe one of the dead people poisoned the others with the deadly fast-acting chemical cyanide. “We are convinced that one of the six people found dead committed this crime,” said Noppasil Poonsawas, a deputy commander of Bangkok police. That person, police said, had ordered the food and tea to the room and “looked under stress” when staff arrived. After conducting interviews with hotel staff, Noppasin said one of the members of the group was alone in the room when the food arrived and was later joined by the other guests. He added that the incident was likely linked to a “personal matter” and not related to organised crime as interviews carried out with relatives of the dead indicated a dispute over debt. “One of the relatives said one of the deceased was an investment agent and all (the deceased) invested, but the business was not going as expected. They made an appointment to discuss the matter in Thailand,” Noppasin said. Police believe that the woman who poisoned the group did so after she accrued huge debts related to an investment in a hospital in Japan, according to police sources cited by Vietnamese media. She had allegedly convinced a married couple and two other victims among the dead to pour funds into the project, but they had reportedly lost roughly $280,000 AUD as a result. Tran Dinh Dung, the father of one of the victims, said his 37-year-old son was due to return to Vietnam last Sunday. “I kept calling him but couldn’t get through so I was very worried, but I didn’t expect him to die in Thailand,” Dung said in an interview with Vietnam’s Thanh Nien newspaper. “Phu’s mother has fainted countless times, she could not bear this shock,” he said.

3 signs your diet is causing too much muscle loss – and what to do about it

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> When trying to lose weight, it’s natural to want to see quick results. So when the number on the scales drops rapidly, it seems like we’re on the right track. But as with many things related to weight loss, there’s a flip side: rapid weight loss can result in a significant loss of muscle mass, as well as fat. So how you can tell if you’re losing too much muscle and what can you do to prevent it? <h2>Why does muscle mass matter?</h2> Muscle is an important factor in determining our metabolic rate: how much energy we burn at rest. This is determined by how much muscle and fat we have. Muscle is more metabolically active than fat, meaning it burns more calories. When we diet to lose weight, we create a calorie deficit, where our bodies don’t get enough energy from the food we eat to meet our energy needs. Our bodies start breaking down our fat and muscle tissue for fuel. A decrease in calorie-burning muscle mass slows our metabolism. This quickly slows the rate at which we lose weight and impacts our ability to maintain our weight long term. <h2>How to tell you’re losing too much muscle</h2> Unfortunately, measuring changes in muscle mass is not easy. The most accurate tool is an enhanced form of X-ray called a dual-energy X-ray absorptiometry (DXA) scan. The scan is primarily used in medicine and research to capture data on weight, body fat, muscle mass and bone density. But while DEXA is becoming more readily available at weight-loss clinics and gyms, it’s not cheap. There are also many “smart” scales available for at home use that promise to provide an accurate reading of muscle mass percentage. However, the accuracy of these scales is questionable. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8122302/">Researchers found</a> the scales tested massively over- or under-estimated fat and muscle mass. Fortunately, there are three free but scientifically backed signs you may be losing too much muscle mass when you’re dieting. <h2>1. You’re losing much more weight than expected each week</h2> Losing a lot of weight rapidly is one of the early signs that your diet is too extreme and you’re losing too much muscle. Rapid weight loss (of more than 1 kilogram per week) results in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5702468/">greater muscle mass loss</a> than slow weight loss. Slow weight loss better preserves muscle mass and often has the added benefit of <a href="https://www.sciencedirect.com/science/article/pii/S0195666312000153">greater fat mass loss</a>. One study compared people in the obese weight category who followed either a very low-calorie diet (500 calories per day) for five weeks or a low-calorie diet (1,250 calories per day) for 12 weeks. While both groups lost similar amounts of weight, participants following the very low-calorie diet (500 calories per day) for five weeks lost <a href="https://pubmed.ncbi.nlm.nih.gov/26813524/">significantly more muscle mass</a>. <h2>2. You’re feeling tired and things feel more difficult</h2> It sounds obvious, but feeling tired, sluggish and finding it hard to complete physical activities, such as working out or doing jobs around the house, is another strong signal you’re losing muscle. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648712/">Research</a> shows a decrease in muscle mass may negatively impact your body’s physical performance. <h2>3. You’re feeling moody</h2> Mood swings and feeling anxious, stressed or depressed may also be signs you’re losing muscle mass. <a href="https://pubmed.ncbi.nlm.nih.gov/26228522/">Research</a> on muscle loss due to ageing suggests low levels of muscle mass can negatively impact mental health and mood. This seems to stem from the relationship between low muscle mass and proteins called neurotrophins, which help regulate mood and feelings of wellbeing. <h2>So how you can do to maintain muscle during weight loss?</h2> Fortunately, there are also three actions you can take to maintain muscle mass when you’re following a calorie-restricted diet to lose weight. <h2>1. Incorporate strength training into your exercise plan</h2> While a broad exercise program is important to support overall weight loss, strength-building exercises are a surefire way to help prevent the loss of muscle mass. A <a href="https://pubmed.ncbi.nlm.nih.gov/29596307/">meta-analysis of studies</a> of older people with obesity found resistance training was able to prevent almost 100% of muscle loss from calorie restriction. Relying on diet alone to lose weight will reduce muscle along with body fat, slowing your metabolism. So it’s essential to make sure you’ve incorporated sufficient and appropriate exercise into your weight-loss plan to hold onto your muscle mass stores. But you don’t need to hit the gym. Exercises using body weight – such as push-ups, pull-ups, planks and air squats – are just as effective as lifting weights and using strength-building equipment. Encouragingly, moderate-volume resistance training (three sets of ten repetitions for eight exercises) <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/sms.14237">can be as effective</a> as high-volume training (five sets of ten repetitions for eight exercises) for maintaining muscle when you’re following a calorie-restricted diet. <h2>2. Eat more protein</h2> Foods high in protein play an essential role in building and maintaining muscle mass, but <a href="https://europepmc.org/article/MED/19927027">research</a> also shows these foods help prevent muscle loss when you’re following a calorie-restricted diet. But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado. <h2>3. Slow your weight loss plan down</h2> When we change our diet to lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering <a href="https://pubmed.ncbi.nlm.nih.gov/25896063/">several physiological responses</a> to defend our body weight and “survive” starvation. Our body’s survival mechanisms want us to regain lost weight to ensure we survive the next period of famine (dieting). <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5764193/">Research</a> shows that more than half of the weight lost by participants is regained within two years, and more than 80% of lost weight is regained within five years. However, a slow and steady, stepped approach to weight loss, prevents our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/38193357/">from activating defence mechanisms</a> to defend our weight when we try to lose weight. Ultimately, losing weight long-term comes down to making gradual changes to your lifestyle to ensure you form habits that last a lifetime. <hr /> At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

Today Show entertainment reporter's cause of death revealed

Beloved Today show and KTLA entertainment reporter Sam Rubin's cause of death has been revealed, two months after his sudden <a href="https://oversixty.com.au/health/caring/legendary-today-show-reporter-dies-unexpectedly" target="_blank" rel="noopener">passing</a>. The 64-year-old died in May with a new report from medical officials finding he died from a heart attack after he suffered a massive blockage to his coronary artery. Just hours after hosting his Hollywood news segment in the morning of May 10th, Rubin was rushed to home after collapsing in his Los Angeles home. The multi-Emmy Award winner was a renowned figure in the news industry on the West Coast, and had covered entertainment, movies and TV for KTLA since 1991. He was also well-known in Australia as a contributor to Channel Nine's Today show and Today Extra, and in the UK where he appeared on This Morning. Following his death, Karl Stefanovic paid tribute to his colleague on Instagram, saying he "adored every second with Sam on air and off over the past two decades". "His spirit. His laugh. His warm caring nature. He was a beautiful man. What a loss. All love to his family, and to his TV family at KTLA5 News." Today Extra host David Campbell also paid tribute to Rubin, calling him a "Hollywood great". "He had an encyclopaedic knowledge of the industry," Campbell posted on social media. "For years we would cross to him and gossip and laugh," he said. "He would visit us Down Under, and whenever you were in LA you had to catch up. His loss is profound. My love and condolences to his family whom he adored." <p style="font-size: 16px; box-sizing: border-box; margin-top: 0px; margin-bottom: 1rem; caret-color: #212529; color: #212529; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji';">"Also his KTLA team who have lost a brother.

Take my (bad) breath away – causes of halitosis and how to check whether you have it

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> In Greek mythology, the many-headed beast <a href="https://mythopedia.com/topics/hydra">Hydra</a> had such severe <a href="https://patient.info/oral-dental-care/bad-breath-halitosis">halitosis</a> that the stench of its breath was deadly to anyone who smelled it. Thankfully, our morning breath might not be that pungent – although eating <a href="https://www.healthline.com/health/get-rid-of-garlic-onion-breath">onions or garlic</a> can put some people in competition with the Hydra. Halitosis has many causes (aside from poor oral hygiene) and can indicate problems with the gut, the sinuses and even the bloodstream. In fact, breath samples can even be tested to make formal diagnoses of health conditions. One condition that can affect the smell of breath is <a href="https://www.diabetes.org.uk/">diabetes mellitus</a>. This is a metabolic disorder where sugar (glucose) is unable to access the body’s cells where it is needed to provide energy, and so rises in the bloodstream. In some instances, such as insufficient insulin dosing, or infection, the body’s response is to break down fats into compounds called ketones to act as a rapid form of fuel. This serious condition is called <a href="https://www.nhs.uk/conditions/diabetic-ketoacidosis/">diabetic ketoacidosis</a>. Ketones have a distinctive scent. <a href="https://www.gov.uk/government/publications/acetone-properties-and-incident-management/acetone-general-information">Acetone</a>, which is also an ingredient in some nail varnish removers, is one of these ketones and has the smell of pear drops. When ketones build up in the bloodstream they easily <a href="https://iopscience.iop.org/article/10.1088/0967-3334/32/8/N01/pdf">diffuse into the breath</a>, giving it a <a href="https://www.medicalnewstoday.com/articles/319683">fruity odour</a>. It’s not just diabetes that can trigger ketone production. <a href="https://pubmed.ncbi.nlm.nih.gov/36033148/">Some diets</a> are based on generating ketones from the breakdown of fats to promote weight loss. These methods, such as the <a href="https://www.healthline.com/nutrition/atkins-diet-101">Atkins diet</a>, force the body to convert fat into energy by restricting carbohydrates. <figure><iframe src="https://www.youtube.com/embed/5U8IDO1fHlU?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Other diets based on the same principles include the <a href="https://patient.info/healthy-living/weight-loss-weight-reduction/52-diet">5:2</a> intermittent fasting diet. On this diet, followers restrict food intake on two days of the week to significantly reduce calorie consumption – and make the body produce ketones. These diets may help weight loss, but the side-effects can be grim. One of the most notorious side-effects is foul breath, although there are also anecdotal reports of <a href="https://www.forbes.com/sites/brucelee/2019/03/03/is-keto-crotch-really-a-side-effect-of-the-keto-diet/">“keto crotch”</a> where some followers of keto diets complain of strong genital odour. <h2>Bacteria and breath</h2> Another cause of bad breath is an <a href="https://iopscience.iop.org/article/10.1088/1752-7155/4/1/017003/pdf">overgrowth of bacteria</a> that produce foul smells. There are plenty of nooks and crannies in the mouth for bacteria to hide, grow and fester, especially the hard-to-clean areas – in between the teeth, and in and around the gums and tongue – or out-of-reach places, such as right at the back of the mouth and the throat. The throat acts as a passage for food, fluids and air. Some patients can develop a condition called <a href="https://www.entuk.org/patients/conditions/49/pharyngeal_pouch_surgery_new">pharyngeal pouch</a>. This is where a pocket forms at the back of the pharynx (the medical name for the throat) in which food and fluids can accumulate, ferment and give breath a pungent odour. Bacteria can also trigger infections in the mouth, like tonsillitis and tooth abscesses where tissues become inflamed, or develop purulence (production of pus). Pus is a collection of different dead cells, including bacteria, and it too can give off a putrid smell. Also, <a href="https://pubmed.ncbi.nlm.nih.gov/25234037/">sinusitis</a> – which is an infection of the air-filled cavities in the skull – can drip foul-smelling infected secretions into the throat, causing bad breath. <h2>Breath tests</h2> Doctors can test breath for bacteria to diagnose some health conditions. For example, <a href="https://pubmed.ncbi.nlm.nih.gov/28891138/">Helicobacter pylori</a>, bacteria that can irritate the gut and lead to the development of potentially dangerous ulcers, turns the compound urea into carbon dioxide. To test for H pylori, a <a href="https://www.nhs.uk/conditions/stomach-ulcer/diagnosis/">diagnostic breath test</a> is performed before and after dosing a patient with urea. If the patient exhales increased levels of carbon dioxide after being dosed with urea, then the test is positive. Breath can also be tested for an overgrowth of bacteria in the <a href="https://www.healthline.com/health/sibo">small intestine</a> (Sibo), which can lead to symptoms like abdominal pain and bloating. Sibo produces gases like hydrogen and methane that can also be detected with a breath test. If you’re worried about pongy breath and don’t have any medical issues, then you can <a href="https://www.healthline.com/health/dental-and-oral-health/how-to-smell-your-own-breath">test your own breath</a>. The age-old method is to lick the back of your wrist, let it dry and then have a sniff. You can also do the same with a tongue scraper, dental floss or a sample of breath exhaled into a cupped hand. <figure><iframe src="https://www.youtube.com/embed/ak5UEM8FK2s?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Often, we can become used to the smell of our own breath. We might only notice when it becomes really bad, or when there are other symptoms, like a foul taste in the mouth. Or when someone plucks up the courage to finally tell you that you have a case of the breath pongs. Suppose someone has broken the news – what do you do now? <a href="https://www.nhs.uk/conditions/bad-breath/">Simple measures can work well</a>, including regular fluid intake – <a href="https://www.dentalhealth.org/bad-breath">dry mouth</a> can lead to bad breath so make sure you’re drinking enough water – and good oral hygiene. This involves brushing the teeth, tongue and flossing between your teeth to eliminate any bacterial hot spots, as well as regular checkups at the dentist. Mouthwash can be an effective temporary solution but there’s evidence that a <a href="https://theconversation.com/eating-leafy-greens-could-be-better-for-oral-health-than-using-mouthwash-221181#:%7E:text=But%20research%20has%20indicated%20that,alternative%20for%20treating%20oral%20disease.">diet rich in leafy greens</a> might be even better at countering bad breath. Smoking is another potential underlying <a href="https://www.healthline.com/health/how-to-get-rid-of-cigarette-breath#1-brush-teeth">cause of halitosis</a>. So if you want sweeter breath, pack in the cigarettes – yet another good reason to give up.<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/231858/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Cancer-causing chemicals found in Aussie tap water sparks safety concerns

A landmark ruling in the US has sparked safety concerns over Australian tap water, with many wondering if it is safe to drink. After the US tightened their regulations around drinking tap water, cutting the maximum level of cancer-causing so-called “forever chemicals” allowed, experts have urged Australia to do the same. Earlier this year, the US Environmental Protection Agency found there was “no safe level of exposure” of the chemicals perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in drinking water and they were likely to cause cancer. The toxic substances have also been linked to kidney and liver disease, thyroid dysregulation, reproductive problems, and developmental problems. According to a federally funded University of Queensland study published in 2011, Australia permits per-and-poly-fluoroalkyl (PFAS) substances at levels up to 140 times higher than those allowed in the US. Health Minister Mark Butler has asked key political players, including Chief Medical Officer Paul Kelly, for an urgent briefing following the US developments. The National Health and Medical Research Council, which shapes the nation’s water rules, is reviewing its guidelines relating to the chemicals, and that could be expedited ahead of its 2025 end date. “Australian drinking water is regularly monitored for the presence of chemicals, including PFAS, to ensure those are within the limits assessed as safe by Australian regulators,” a spokesperson for the Health Minister said. “This independent review will consider recent guidance and reviews from international and national jurisdictions and determine whether they are suitable to adopt or adapt for Australia.” Nicholas Chartres, a senior research fellow at the University of Sydney, called for a precautionary approach and immediate widespread testing of the nation’s water supplies. “The government needs to take action. They need to be testing the water (and) it will come at a cost,” he said. Image credits: Shutterstock

Michael Mosley's cause of death revealed in autopsy

The sudden and tragic death of renowned TV doctor Michael Mosley has left his fans and family in deep sorrow. New details from an initial autopsy report reveal the beloved health expert likely died of natural causes during a challenging trek on the Greek island of Symi. Mosley disappeared on a Wednesday afternoon after bidding farewell to his wife on Saint Nikolas Beach. He inadvertently took a wrong turn, embarking on a gruelling two-hour hike in intense heat. According to The Sun, he tragically collapsed near a beach bar at Agia Marina, just a few metres away from safety. His body was discovered five days later by a television crew from Greece's ERT public channel. The initial autopsy indicated that Mosley most likely succumbed to natural causes at around 4pm on the day he went missing. The scorching temperatures, exceeding 40°C in the rocky terrain, contributed to the arduous conditions he faced. The post-mortem examination revealed no external injuries that could have caused his death. The position of his body suggested that he had sat down to rest against a wall before losing consciousness and passing away. CCTV footage captured Mosley walking slowly through the mountainous area, indicating exhaustion. His last recorded sighting was at 2pm in Pedi, implying he had been navigating the rough terrain for nearly two hours. The grainy footage showed him collapsing near a wall and barbed wire fence, just 100m from the beach resort and shoreline. Despite extensive search efforts, including drones, helicopters and specially trained dogs, Mosley’s body was not found until five days later. The condition of his body made it challenging to pinpoint the exact cause of death, but it was clear he was extremely close to reaching safety before he collapsed. The search for Dr Mosley mobilised the small island community of Symi, with 2600 residents and numerous volunteers talking part. His wife, Dr Claire Bailey, expressed her profound grief in a heartfelt statement. “I don’t know quite where to begin with this,” she said. “It’s devastating to have lost Michael, my wonderful, funny, kind and brilliant husband. “We had an incredibly lucky life together. We loved each other very much and were so happy together. I am incredibly proud of our children, their resilience and support over the past days. “My family and I have been hugely comforted by the outpouring of love from people from around the world. It’s clear that Michael meant a huge amount to so many of you. “We’re taking comfort in the fact that he so very nearly made it. “He did an incredible climb, took the wrong route and collapsed where he couldn’t be easily seen by the extensive search team. “Michael was an adventurous man, it’s part of what made him so special. “We are so grateful to the extraordinary people on Symi who have worked tirelessly to help find him. “Some of these people on the island, who hadn’t even heard of Michael, worked from dawn till dusk unasked. We’re also very grateful to the press who have dealt with us with great respect. “I feel so lucky to have our children and my amazing friends. Most of all, I feel so lucky to have had this life with Michael.” Dr Mosley was a respected and beloved figure in the medical and television community. Known for his insightful health advice and engaging personality, he had a significant impact on many lives. His adventurous spirit and dedication to promoting health and well-being will be remembered fondly by all who knew him. Image credits: Ken McKay/ITV/Shutterstock Editorial / Facebook

1 in 5 deaths are caused by heart disease, but what else are Australians dying from?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/garry-jennings-5307">Garry Jennings</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Nobody dies in good health, at least in their final moments. But to think the causes of death are easy to count or that there is generally a single reason somebody passes is an oversimplification. In fact, in 2022, four out of five Australians had multiple conditions at the time of death listed on their death certificate, and almost one-quarter had five or more recorded. This is one of many key findings from a <a href="https://pp.aihw.gov.au/reports/life-expectancy-deaths/what-do-australians-die-from/contents/about">new report</a> from the Australian Institute of Health and Welfare (AIHW). The report distinguishes between three types of causes of death – underlying, direct, and contributory. An underlying cause is the condition that initiates the chain of events leading to death, such as having coronary heart disease. The direct cause of death is what the person died from (rather than with), like a heart attack. Contributory causes are things that significantly contributed to the chain of events leading to death but are not directly involved, like having high blood pressure. The report also tracks how these three types of causes can overlap in deaths involving multiple causes. In 2022 the top five conditions involved in deaths in Australia were coronary heart disease (20% of deaths), dementia (18%), hypertension, or high blood pressure (12%), cerebrovascular disease such as stroke (11.5%), and diabetes (11.4%). <hr /> <iframe id="MzQHA" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/MzQHA/" width="100%" height="400px" frameborder="0"></iframe> <hr /> When the underlying cause of death was examined, the list was similar (coronary heart disease 10%, dementia 9%, cerebrovascular disease 5%, followed by COVID and lung cancer, each 5%). This means coronary heart disease was not just lurking at the time of death but also the major underlying cause. The direct cause of death however was most often a lower respiratory condition (8%), cardiac or respiratory arrest (6.5%), sepsis (6%), pneumonitis, or lung inflammation (4%) or hypertension (4%). <h2>Why is this important?</h2> Without looking at all the contributing causes of death, the role of important factors such as coronary heart disease, sepsis, depression, high blood pressure and alcohol use can be underestimated. Even more importantly, the various causes draw attention to the areas where we should be focusing public health prevention. The report also helps us understand which groups to focus on for prevention and health care. For example, the number one cause of death in women was dementia, whereas in men it was coronary heart disease. <hr /> <iframe id="NosVz" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/NosVz/" width="100%" height="400px" frameborder="0"></iframe> <hr /> People aged under 55 tended to die from external events such as accidents and violence, whereas older people died against a background of chronic disease. <hr /> <iframe id="1l3OS" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/1l3OS/" width="100%" height="400px" frameborder="0"></iframe> <hr /> We cannot prevent death, but we can prevent many diseases and injuries. And this report highlights that many of these causes of death, both for younger Australians and older, are preventable. The top five conditions involved in death (coronary heart disease, dementia, hypertension, cerebrovascular disease and diabetes) all share common risk factors such as tobacco use, high cholesterol, poor nutrition, physical inactivity, or are risk factors themselves, like hypertension or diabetes. <hr /> <iframe id="7Eb8O" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/7Eb8O/" width="100%" height="400px" frameborder="0"></iframe> <hr /> Tobacco use, high blood pressure, being overweight or obese and poor diet were attributable to a combined 44% of all deaths in this report. This suggests a comprehensive approach to health promotion, disease prevention and management is needed. <hr /> <iframe id="2MmGg" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/2MmGg/" width="100%" height="400px" frameborder="0"></iframe> <hr /> This should include strategies and programs encouraging eating a healthy diet, participating in regular physical activity, limiting or eliminating alcohol consumption, quitting smoking, and seeing a doctor for regular health screenings, such as the Medicare-funded <a href="https://www.heartfoundation.org.au/your-heart/heart-health-checks">Heart Health Checks</a>. Programs directed at accident prevention, mental health and violence, especially gender-related violence, will address untimely deaths in the young.<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/231598/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/garry-jennings-5307">Garry Jennings</a>, Professor of Medicine, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Here’s what happens to your body during plane turbulence – and how to reduce the discomfort it causes

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> This week has seen another barrage of <a href="https://www.theguardian.com/uk-news/2024/jan/22/uk-weather-storm-jocelyn-to-follow-isha-with-more-strong-winds-and-heavy-rain">unsettled weather</a> sweep across the UK, with many flights delayed or cancelled. Some of those who were fortunate enough to take off found themselves arriving at destinations that weren’t on their boarding passes – such as passengers travelling from Stansted to Newquay who eventually diverted to <a href="https://uk.news.yahoo.com/storm-isha-creates-flight-diversion-142821278.html">Malaga</a>. One thing that was consistently described by passengers was that parts of the flights and the attempted landings were some of the most unnerving they’d ever experienced, due to turbulence. Turbulence results from uneven air movement, which is <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL103814">increasing</a> in frequency. If you turn your hair dryer on at home and hold it still, the air moves at a constant rate, but once you begin drying your hair and moving the hairdryer around, the air movement becomes uneven, that is to say, turbulent. Although turbulence may be unnerving and make you feel unwell, it is important to recognise that it is very common and typically <a href="https://pubmed.ncbi.nlm.nih.gov/18018437/">nothing to worry about</a> if you’re in your seat with your seatbelt fastened. <h2>How the body detects and responds to turbulence</h2> The body recognises itself within any environment. Its relationship with objects in terms of distance and direction is called <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780123750006003414">spatial orientation</a>. When flying, this is typically moving forwards, ascending, some turns and a descent. However, turbulence disrupts this relationship and confuses the sensory information being received by the brain – it makes the body want to respond or recalibrate. Our inner ears play a pivotal role in all this. It consists of complex apparatuses that undertake more than hearing. These include the cochlea, <a href="https://www.ncbi.nlm.nih.gov/books/NBK279394/">three semi-circular canals</a>, <a href="https://radiopaedia.org/articles/utricle-ear?lang=gb">the utricle</a> and <a href="https://radiopaedia.org/articles/saccule-ear-1?lang=gb">the saccule</a>. The cochlea is responsible for hearing. It converts <a href="https://www.ncbi.nlm.nih.gov/books/NBK531483/">sound energy into electrical energy</a> that is then “heard” by the brain. The remaining structures are responsible for the balance and position of the head and body. The semi-circular canals are positioned in a vertical (side to side), horizontal and front-to-back plane, detecting movement in a nodding, shaking and touching ear-to-shoulder direction. Attached to these canals are <a href="https://www.ncbi.nlm.nih.gov/books/NBK532978/">the utricle and saccule</a>, which can detect <a href="https://www.ncbi.nlm.nih.gov/books/NBK10792/">movement</a> and <a href="https://www.cell.com/current-biology/pdf/S0960-9822(05)00837-7.pdf">acceleration</a>. All of these apparatuses use microscopic hair cells in a specialised fluid called <a href="https://www.ncbi.nlm.nih.gov/books/NBK531505/">endolymph</a> that flows with the head to create a sense of movement. When the plane encounters turbulence, this fluid moves around, but unpredictably. It takes <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">about ten to 20 seconds</a> for the fluid to recalibrate its position, while the brain struggles to understand what is going on. When the aircraft hits turbulence, the balance apparatus <a href="https://www.frontiersin.org/articles/10.3389/fneur.2023.949227/full">cannot distinguish</a> the movement of the plane from that of the head, so the brain interprets the aircraft movement as that of the head or body. But this doesn’t match the visual information being received, which causes sensory confusion. The reason the inner ear causes so much confusion is because during flights you are devoid of your primary sensory tool relative to the external environment – your sight and the horizon. Eighty per cent of <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">spatial information</a> comes from your eyes during flight. However, you only have the seat in front of you or the cabin as a reference point, which means your inner ear becomes the dominant sensory message to the brain during turbulence and disrupts the <a href="https://www.ncbi.nlm.nih.gov/books/NBK545297/">“vestibulo-ocular reflex”</a>. This reflex keeps your vision <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4130651/">aligned</a> with your balance or expected position. Vision is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6777262/">most valued</a> of the senses and one-third of the brain is attributed to its function, reinforcing its importance in spatial orientation. This sensory mixed messaging often results in things like dizziness and sweating as well as gastrointestinal symptoms, such as <a href="https://www.airmedicaljournal.com/article/S1067-991X(02)70038-2/fulltext">nausea and vomiting</a>. Motion sickness can be triggered by turbulence and although research into specific airsickness is limited, other modes that induce motion sickness suggest that <a href="https://pubmed.ncbi.nlm.nih.gov/16018346/">women</a> are <a href="https://pubmed.ncbi.nlm.nih.gov/26466829/">more susceptible</a> than men, particularly in the <a href="https://pubmed.ncbi.nlm.nih.gov/16235881/">early stages</a> of the menstrual cycle. The turbulence also causes an increase in your heart rate, which is already higher than normal when flying because of a <a href="https://pubmed.ncbi.nlm.nih.gov/15819766/">decrease in oxygen saturation</a>. <h2>What about the pilots?</h2> Commercial pilots accrue thousands of hours at the controls, they are subject to the same forces as the passengers. Over time, they can <a href="https://academic.oup.com/milmed/article/180/11/1135/4160573">adapt to these forces</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15828634/">experiences</a>, but they also have a couple of additional resources that most passengers don’t. They have the view out of the cockpit windows, so have a horizon to use as a reference point and can see what lies immediately ahead. If it is cloudy or visibility is low, their instruments provide additional visual <a href="https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/phak/19_phak_ch17.pdf">reference</a> to the position of the aircraft. This doesn’t mean they are immune to the effects of turbulence, with some studies reporting up to <a href="https://pubmed.ncbi.nlm.nih.gov/26540704/">71% of trainee pilots</a> reporting episodes of airsickness. <h2>How to reduce the discomfort</h2> A window seat can help, or even looking out the window. This gives the brain some sensory information through visual pathways, helping calm the brain in response to the vestibular information it is receiving. If you can get one, a seat towards the front or over the wing reduces the effects of turbulence. Deep or rhythmical breathing can help reduce motion sickness induced by turbulence. Focusing on your breathing <a href="https://pubmed.ncbi.nlm.nih.gov/25945662/">calms the nervous system</a>. Don’t reach for the alcohol. While you may feel it calms your nerves, if you hit turbulence it’s going to interfere with your <a href="https://pubmed.ncbi.nlm.nih.gov/7610847/">visual and auditory processing</a> and increase the likelihood of vomiting. If you suffer from motion sickness and are worried about turbulence while flying, then there are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6241144/">drugs that can help</a>, including certain <a href="https://www.nhs.uk/medicines/cinnarizine/about-cinnarizine/">antihistamines</a>. Finally, it’s important to remember that although turbulence can be unpleasant, aircraft are designed to withstand the forces it generates and many passengers, even frequent fliers, will rarely encounter the most severe categories of turbulence because pilots actively plan routes to avoid it.<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/221780/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"It’s a nightmare": Star golfer's cause of death revealed

Two-time PGA Tour winner Grayson Murray has died at the age of 30. Golf officials announced his death on Sunday morning, with PGA Tour commissioner Jay Monahan releasing a statement. “We were devastated to learn — and are heartbroken to share — that PGA Tour player Grayson Murray passed away this morning,” Monahan said. “I am at a loss for words. The PGA Tour is a family, and when you lose a member of your family, you are never the same" Murray's parents later confirmed that their son took his own life, just one day after he withdrew from the second round of the Charles Schwab Challenge - a PGA Tour event - due to illness. “We have spent the last 24 hours trying to come to terms with the fact that our son is gone,” his parents, Eric and Terry Murray said in a statement. “It’s surreal that we not only have to admit it to ourselves, but that we also have to acknowledge it to the world. It’s a nightmare.” "We have so many questions that have no answers. But one. Was Grayson loved? The answer is yes. By us, his brother Cameron, his sister Erica, all of his extended family, by his friends, by his fellow players and — it seems — by many of you who are reading this. He was loved and he will be missed. “Life wasn't always easy for Grayson, and although he took his own life, we know he rests peacefully now.” They have also asked for privacy and for people to honour Murray by being kind to one another. Murray has previously been open about his battle with depression and alcoholism, according to The NY Post. He talked about turning the corner in his life and being eight months sober, after winning the Sony Open in Honolulu in January. “It's not easy,” Murray said immediately after winning. "I wanted to give up a lot of times. Give up on myself. Give up on the game of golf. Give up on life, at times.” Murray tied for 43rd last week in the PGA Championship, which earned him a spot in the US Open next month at Pinehurst No.2 in North Carolina. The PGA Tour commissioner said he spoke with Murray's parents about halting play, but they insisted the golf tournament to continue. “We mourn Grayson and pray for comfort for his loved ones. I reached out to Grayson’s parents to offer our deepest condolences, and during that conversation, they asked that we continue with tournament play. They were adamant that Grayson would want us to do so," he said. Monahan flew to Fort Worth, Texas, on Sunday to be with players, and many of them wore black-and-red pins on their caps - the colours of the Carolina Hurricanes, Grayson's favourite NHL team - to honour the golfer.

Sarah, who is also an actress, previously confirmed the news of his death in a heartbreaking tribute post to her late sibling, saying he "is gone much too soon". "It is with great sadness that we announce the passing of Brian James McCardie (59), beloved son, brother, uncle and dear friend to so many," her post began. "Brian passed away suddenly at home on Sunday 28th April. A wonderful and passionate actor on stage and screen, Brian loved his work and touched many lives, and is gone much too soon." "We love him and will miss him greatly; please remember Brian in your thoughts." The post was flooded with comments of condolences, as one person wrote, "One of Scotland's greats on both the stage and the screen." McCardie was best known for his role as Tommy Hunter on BBC's Line of Duty, the show Time with Sean Bean, and the film Rob Roy co-starring Liam Neeson. Image credits: BBC / Instagram
