The Science Behind Cold Exposure and Weight Loss Wearing an ice vest or taking daily cold showers could help people lose weight, according to researchers. Despite the growing popularity of cold-water swimming and freezing plunges, to date there is minimal data on the health benefits of cold exposure. But a study of 47 adults with obesity or overweight has found that regular exposure to cold temperatures led to fat loss. The Study's Methodology and Findings Researchers at the University of Nottingham and the Leiden University Medical Center (LUMC) in the Netherlands gave half the participants an ice vest and waist wrap to wear for two hours every morning, while continuing their daily lives. The vests and waist wrap were worn on top of a thin T-shirt and contained gel-filled cooling packs that had been kept overnight in the freezer and maintained a temperature of 15C. In six weeks, participants lost 0.9kg (2lb), made up almost entirely of body fat, whereas the control group did not lose any weight and put on 0.6kg (1.3lb) on average. The Impact of Cold Exposure on Metabolism The lead researcher, Dr Mariëtte Boon, of LUMC, said: “This is one of the first studies looking at the impact of cold exposure over a prolonged period of time, involving people with overweight and obesity.” She added: “Vests like this can be worn at home and so cold exposure could be a simple and inexpensive addition to lifestyle strategies for weight loss such as healthy eating and physical activity.” The Potential for Cold Showers as a Weight Loss Tool The researchers, jointly funded by the Dutch Heart Foundation and the British Heart Foundation, are investigating whether other forms of regular cold exposure could reduce obesity, inflammation and prevent heart disease. The authors are conducting a separate study of 34 women in the Netherlands to see if cold showers also promote fat loss. Half of the women will have their shower on the coldest setting for 90 seconds every morning.

The Global Obesity Landscape: Not a Uniform EpidemicA continuing rise in obesity around the world is not inevitable, research suggests, with rates in some countries levelling off or potentially in decline. Researchers say focusing on what has been described as a global epidemic of obesity hides large variations in trends across different countries, sexes and age groups.Majid Ezzati, a professor of global environmental health at Imperial College London and author of the study, said: "I think the thing that's really important is this diversity exists even across countries that have really similar economic, environmental, technological features. So countries may look the same on the surface of it but obesity looks different."Comprehensive Analysis Reveals Complex PatternsWriting in the journal Nature, the international team, which involved a network of almost 2,000 researchers, described how for each country they calculated the change in the prevalence of obesity each year between 1980 and 2024. They drew on data from 4,050 population-based studies involving 232 million participants aged five years and above.They found that the prevalence of obesity increased in almost all countries over the 45-year period. However, in most high-income countries, a rapid rise in the prevalence of obesity has been replaced by a slower increase, a plateau, or a potential decline.Regional Variations in Obesity PrevalenceThe rate of growth in obesity is slowing in adults in the US and UK, reaching a prevalence of 40-43% and 27-30% respectively in 2024. Obesity is increasing steadily in Finland, has plateaued in Germany and may have started to decline in France, where 24-25%, 20-23% and 11-12% of adults respectively were thought to have the condition in 2024.Slowdowns were often seen in children and adolescents before adults. For the former group, the slowdown started as early as 1990 in Denmark and rates stabilised in most high-income countries by the mid-2000s. Obesity has plateaued in boys and girls in the UK, US, Germany and Japan at prevalences of 10-12%, 20-23%, 7-12% and 3-7% respectively.Meanwhile, obesity among young people and adults in many low-income and middle-income countries continues to rise and in some cases this is accelerating.Understanding the Drivers Behind Divergent TrendsThe team say it is important now to unpick what is behind the trends in different countries. The situation is complex: while there may be shared reasons for obesity, such easy access to unhealthy foods or a decrease in physical activity, the team say country-specific factors rooted in social, economic and policy considerations could also be important, from perceptions around body image to the presence or absence of interventions such as healthy school meals.Naveed Sattar, a professor of metabolic medicine at the University of Glasgow, who was not involved in the work, said the study highlighted how obesity trends were diverging sharply across countries. "English-speaking nations are doing particularly poorly, with the UK now among the countries with the highest obesity levels worldwide," he said.Sattar said it was encouraging that some countries appeared to have reached a plateau in obesity rates. "Understanding what has worked in those settings is crucial as it could help shape more effective public health strategies for the UK," he said, although he noted there could be country-specific aspects or customs at play.Future Outlook and Potential InterventionsHe said the rapid rise in obesity across many developing countries was especially concerning, not least as it could result in increases in diabetes and cardiovascular conditions.He added: "Looking ahead, it will be important to see how wider use of effective weight-loss medicines affects obesity trends, particularly in the UK and the United States. Recent signs of stabilisation in the USA suggest there may be room for cautious optimism. Combining evidence-based medicines with strong public health measures could begin to shift obesity rates in the right direction."

The Unseen Consequences of School Sports A recent survey by Age UK revealed that over 4 million mid-lifers in the UK remain traumatized by their experiences in PE lessons at school. This trauma often leads to a lifelong aversion to physical activity, with many people feeling unwelcome or excluded from sports. The Need for a New Approach Experts argue that a shift towards more inclusive and adaptive sports programs can help change this narrative. Mark Davies, an entrepreneur and former chair of British Rowing and Archery GB, has advocated for linking local schools and sports clubs to make physical activity more accessible. The Power of Positive Experiences Positive experiences in sports can have a profound impact on individuals, providing a sense of community, joy, and belonging. The author shares their own experience of discovering rowing at university, which gave them a chance to experience sports differently and find a lifelong passion. Towards a More Holistic Approach A more holistic approach to sports and physical activity is needed, one that prioritizes positive experiences and adapts to individual needs. The sport for development sector has shown promising results in using sports to tackle social issues, such as crime and education. A Call to Action As the UK continues to grapple with issues of physical inactivity, it's clear that a new approach is needed. By prioritizing positive experiences and inclusivity in sports, we can work towards a healthier, happier society.

England Reaches a Fitness MilestoneEngland has achieved a historic milestone in public health, with the latest Active Lives survey revealing that over 30 million adults are now meeting the recommended guideline of 150 minutes of moderate physical activity per week. This represents a record high for the nation, marking a significant turnaround in public health trends following the disruptions of the pandemic.The Silver Surge: Demographic Shifts in ExerciseThe most striking development in this decade-long report is the dramatic rise in activity among older demographics. The over-75s have seen a 11% growth in participation over the last ten years, while the 55-74 age group has increased by 7%. This shift is largely attributed to changing habits, including a sustained increase in walking for leisure and a boom in "fitness activities" like gym attendance, which has reached a 10-year high of 15.3 million.The Persistence of the Divide: Regional and Socioeconomic GapsDespite the national record, the data exposes deep-seated inequalities. Activity levels among Black and Asian adults have remained stagnant at 57% and 56% respectively over the last decade. Furthermore, the least affluent in society have seen a decline, with only 53.8% of the poorest adults meeting the target, a drop from 54.8% a decade ago.Regional Disparity: The West Midlands remains the least active region, recording only 1.7% growth over a decade compared to the 3.5% growth seen in the South West.Volunteer Impact: The growth is attributed to millions of volunteers and a renewed national awareness of the benefits of physical health.Future Outlook: Bridging the Equity GapWhile the overall trend is positive, the stagnation in specific ethnic and socioeconomic groups signals that current strategies are insufficient for universal adoption. The future of public health in England will depend on targeted interventions in the West Midlands and efforts to make fitness more accessible to minority communities and lower-income households.

The metal music scene has witnessed a surge in popularity of masked bands, with many notable acts donning elaborate masks as part of their stage presence. This trend is not only visually striking but also allows the bands to create a sense of mystery and anonymity. For bands like Imperial Triumphant, Gaerea, Sleep Token, Ghost, and Gwar, their masks have become an integral part of their image and artistry.Imperial Triumphant, an avant-garde metal band from the US, chose to wear striking gold masks modeled after 1920s art deco architecture. These masks brought their own set of problems, including getting lost in transit. The band's singer/guitarist, Zachary Ezrin, notes that the masks add a layer of complexity to their music, allowing them to tap into different parts of their personalities.Gaerea, a Portuguese black metal band, has also adopted the trend of wearing masks. Lead singer Alpha notes that the mask allows him to get into a different mode in his psyche, similar to how athletes get into a trance-like state during intense physical activity. The band's masks are not just for show; they also help to create a sense of anonymity, allowing the band to focus on their music rather than their individual identities.The use of masks in metal music is not a new phenomenon. Bands like Gwar and Slipknot have been using masks for decades, and their influence can be seen in many modern metal bands. However, the current trend of masked bands goes beyond just shock value; it's about creating a sense of mystery and artistry.The masks also allow bands to create elaborate mythologies and universes that fans can engage with. For example, Ghost poses as a subversive, devil-worshipping church, while Sleep Token's songs are ostensibly about their devotion to a god called Sleep. These mythologies help to create a sense of depth and complexity, drawing fans into the band's world.Despite the challenges of performing in masks, many bands find that it allows them to access new parts of their personalities and create a more immersive experience for their fans. As Ezrin notes, "I love the presentation of Imperial Triumphant... Even in 2026, when there are a million masked bands out there, I'd say we're still unique."

The Black Country, a region in the West Midlands, is grappling with the highest levels of physical inactivity in England. With 1.2 million residents, it is one of the poorest parts of the country, and the statistics are stark: 28.4% of adults in the West Midlands are physically inactive, with some areas like Sandwell and Walsall recording even higher rates of inactivity.However, local volunteers and organizations are taking proactive steps to address this issue. Kelvin Gilkes, founder of the Pendeford Community Bike Hub, is working to encourage people to get active through cycling. His initiative not only provides a space for people to repair and ride bicycles but also aims to expand horizons and promote physical activity among community members.Another initiative is led by Tracy Tromans, who runs a weekly walking group through Leasowes park in Halesowen. Her group focuses on friendship and being aware of everyone's limitations, gently encouraging people to leave their homes and get moving. Nadia Inglis, director of public health for Walsall, emphasizes the benefits of physical activity, including lowering the risk of chronic conditions and improving mental wellbeing.Organizations like Sport England and Active Black Country are also playing a crucial role in supporting local initiatives. They are funding networks of 'place-based' Active Partnerships to improve physical activity in areas where it is scarce. The goal is to turn local insight into community action and create a broader impact.These community-driven initiatives offer a glimmer of hope in the face of a significant challenge. By making parks more accessible and promoting non-traditional activities, such as Nerf clubs, these efforts aim to unlock spaces and encourage people to get active. While change is slow, there is a sense of momentum and ownership within the community, which is essential for long-term success.

The UK government has introduced new guidelines aimed at helping parents manage their children's screen time. Children under five should spend no more than an hour a day on screens, according to the advice developed by a panel led by the children's commissioner, Rachel de Souza, and children's health expert Prof Russell Viner.For children under two, screen time should be avoided except for shared activities that encourage interaction. The guidance also suggests that bedtimes and mealtimes should be screen-free, with families encouraged to opt for background music, table games, bedtime stories, and colouring instead.Prime Minister Keir Starmer emphasized that the guidance will help families keep children safe and build healthy habits with screens. He stated, “Parenting in a digital world can feel relentless. Screens are everywhere, and the advice is often conflicting. My government will not leave parents to face this battle alone.”The panel's review found that long periods of solo screen time can harm sleep, physical activity, creative play, and interaction with parents, which are crucial for good development. About 98% of children watch screens daily by the age of two, and high screen time has been linked to impacts on language development.Prof Russell Viner noted, “Too much solo screen time can crowd out the things that make the biggest difference – sleep, play, physical activity and talking with parents and carers.” The guidance also recommends that parents consider their own screen use in front of their children and explore screen-free periods for the whole family.

A recent study published in the European Journal of Preventive Cardiology has revealed that small changes to daily habits can have a significant impact on cardiovascular health. The research, conducted by experts from Australia, Chile, and Brazil, examined data on more than 53,000 middle-aged UK adults taking part in the Biobank study.The study found that sleeping for 11 minutes more each night, doing 4.5 additional minutes of brisk walking, and eating an extra 50g of vegetables each day can reduce the risk of major cardiovascular events, including heart attacks and strokes, by about 10%. These small behavior changes were found to be more "achievable and sustainable" compared to attempting major changes in a single behavior.According to the study, the "optimal" way to avoid cardiovascular incidents includes getting eight to nine hours of sleep each night, a good diet, and a minimum of 42 minutes of moderate-to-vigorous physical activity each day. Combining these measures leads to a 57% lower risk of heart attacks and strokes.Dr. Nicholas Koemel, the study's lead author, noted that "making a few small, combined changes is likely more achievable and sustainable for most people when compared with attempting major changes in a single behavior." He encouraged people to make small changes to their daily routine, as they can have a surprisingly large positive impact on cardiovascular health.Prof Emmanuel Stamatakis, a senior author of the study, plans to build on these findings to develop new digital tools that support people in making positive lifestyle changes and establishing sustained healthy habits.Commenting on the study, Emily McGrath, a senior cardiac nurse at the British Heart Foundation, said that "small tweaks – like getting a little more sleep, adding a few extra minutes of activity to your day or eating a bit more veg – can work together to have a meaningful positive impact on your heart health."
