A new wave of scientific concern is cresting over cannabis use, as recent research finds that using marijuana—whether smoked or eaten in gummies—is directly associated with significant risks to heart health. The findings, published in JAMA Cardiology and led by researchers at the University of California, San Francisco (UCSF), upend the common belief that cannabis is a safer or even harmless alternative to tobacco, particularly as legalization and recreational use continue to rise worldwide, including in Thailand.

A new study raises serious concerns about cannabis and heart health. Research led by investigators at UCSF and published in JAMA Cardiology shows that cannabis use—whether smoked or consumed as edibles—may impair cardiovascular function. The findings challenge the idea that cannabis is a safer alternative to tobacco, especially as legalization and consumer use expand globally, including in Thailand.

For Thai readers, the study arrives at a moment when policy, health messaging, and potential economic benefits of cannabis are hotly debated. Thailand has moved to legalize certain cannabis activities, creating a local landscape where public health guidance needs to keep pace with evolving regulations. The new evidence underscores the importance of clear information for patients, clinicians, and regulators.

A beloved physical activity endorsed by millions for its health benefits—long-distance running—may be unexpectedly associated with a higher risk of developing precancerous colon growths among young adults, according to a new study presented at the prestigious American Society of Clinical Oncology (ASCO) 2025 conference in Chicago. The study, conducted by researchers based in Washington, DC, challenges the prevailing wisdom that vigorous aerobic exercise is universally protective against all forms of cancer, raising pressing questions for health-minded Thais—especially the country’s growing cohort of marathon and ultramarathon enthusiasts.

A new international review, released May 31, 2025, synthesizes cardiology perspectives to highlight eight clear signs that should prompt a visit to a heart specialist. The findings are particularly relevant for Thailand, where cardiovascular disease remains a leading cause of death and disability. Data from Thailand’s public health system show heart disease continues to impose a heavy burden, underscoring the need for earlier detection and prevention. Research from leading institutions and local guidelines emphasize that cardiovascular risk is not limited to older adults; awareness must span all ages in Thai communities.

A widely celebrated form of exercise, long-distance running, may be linked to an unexpected risk among certain young adults. A study presented at ASCO 2025 in Chicago found a higher-than-expected rate of colon adenomas—precancerous growths—in adults aged 35 to 50 who regularly run ultramarathons or multiple marathons. The results prompt careful discussion for health-minded Thai runners, where endurance events have surged in popularity in recent years.

The investigation examined 100 runners who completed at least two ultramarathons (over 50 km) or five standard marathons (42 km) within a defined period. Among participants, 41% had at least one adenoma and 15% had advanced adenomas. These rates appeared higher than typical figures for the general population. About half of those with advanced lesions reported rectal bleeding, a symptom sometimes mistaken for benign exercise-related issues such as runner’s colitis.

Emerging research and expert consensus warn that many early signs of heart problems go undetected until serious health consequences arise, urging Thai readers to take seemingly mild symptoms more seriously. A new review featuring leading cardiologists, published on May 31, 2025, details the top eight signs that should prompt a visit to a heart specialist and contextualizes the relevance for Thai society, where cardiovascular disease remains one of the primary causes of death and disability (EatingWell, Statista, WHO, RCPT Guidelines).

New research highlighted by The Guardian shows videos range from trivializing serious conditions to promoting unproven treatments. Experts warn this trend fuels stigma and risky self-diagnosis, a particularly worrying development for Thai youth who spend大量 time on the platform.

Mental health has become a front-line issue in Thailand. The Covid-19 era intensified stress and isolation for young people and working adults. TikTok ranks among the most downloaded apps in Thailand, with millions turning to it for support and information. Data from Thailand’s Mental Health Department indicates rising cases of depression and anxiety since 2020, and digital platforms are increasingly a primary health resource for many young adults. The Bangkok Post notes these trends and underscores the need for accurate information in a country where health literacy varies by region and access remains uneven.

The viral popularity of mental health content on TikTok has led to a surge in misleading advice and misconceptions, with new research highlighted by The Guardian revealing that misinformation ranges from trivializing serious conditions to promoting unproven treatments. Experts warn that this trend not only stokes confusion but also risks worsening stigma and driving unsafe self-diagnosis—an especially troubling development for young Thais heavily active on the platform.

Mental health issues have become a frontline concern in Thai society, particularly since the Covid-19 pandemic intensified stress and isolation among youth and working adults. With TikTok ranking among the most downloaded apps in Thailand and millions of Thai users turning to the platform for support and information, the spread of health misinformation is a pressing national challenge. According to Mental Health Department statistics, Thailand saw significant increases in reported cases of depression and anxiety since 2020, and digital platforms are now a primary health resource for many young adults (Bangkok Post).

New scientific findings are challenging the popular belief that waking up at dawn and taking cold showers automatically boosts success. A recent analysis argues that these morning rituals work for some, but are not universal superpowers. For millions who have followed them, the question now is whether the benefits are real or overstated.

In Thailand, the trend of “morning mastery” has grown online and in seminars over the past decade. Executives, students, and wellness enthusiasts alike have embraced early rising and cold showers hoping to sharpen focus and productivity. Yet the latest studies suggest the outcomes are more nuanced than advertised.

A flurry of new scientific research is challenging the long-held beliefs popularized by self-help and productivity gurus: that waking up at dawn and taking cold showers are surefire ways to supercharge your success. According to a recent article, “Science has debunked the morning mantra of productivity gurus: cold showers are just as useless as waking up early,” leading experts now say the effectiveness of these morning rituals is more myth than magic, raising questions for millions who have faithfully followed these regimens for years (thinkstewartville.com).

A senior psychiatry researcher from a leading U.S. medical center, who also lives with bipolar disorder, recently shared her diagnosis, daily management, and cutting-edge treatment developments on a popular science podcast. Her unique perspective—balancing scientist and patient roles—offers both human insight and scientific clarity about a condition that remains stigmatized in many societies, including Thailand.

For Thai readers, the topic hits close to home. Mental health care in Thailand continues to improve but still faces stigma, gaps in access, and shortages of trained professionals, particularly in rural areas. As global research advances, Thai families, educators, and health officials can learn from international experiences to strengthen local responses and reduce barriers to care.

A recent study from the United States has sent shockwaves through the public health community, revealing that alcohol-related cancer deaths have doubled over the past 30 years—a trend with significant lessons for Thailand, where drinking patterns are changing rapidly. The new data, released by the Moffitt Cancer Center and highlighted in the Hudson Valley Post, underscore the role of alcohol as a major carcinogen, fueling thousands of preventable cancer deaths each year not just in New York but worldwide. The findings reinforce warnings from global health authorities, and Thai experts are increasingly concerned about similar risks at home, particularly as alcohol consumption trends upwards in both urban and rural settings.

A UCSF study shows regular cannabis use, whether smoked or eaten, may impair cardiovascular health to a degree similar to tobacco. Published in JAMA Cardiology, the findings highlight potential risks that matter for Thai readers as the country debates cannabis policy and market growth.

In Thailand, cannabis reform began in 2022, with a rapid expansion of dispensaries, edibles, and wellness products. The new data from the United States adds scientific nuance to ongoing debates about benefits, risks, and regulation in a setting where public health messaging is still catching up with industry momentum. Data from Thai health authorities indicate a growing number of cannabis-related businesses, especially in major cities and tourist areas. Public health messaging has tended to emphasize economic opportunity and wellness, underscoring the need for balanced information about cardiovascular risks.

A recent study from the University of Montreal shows that caffeine consumed in the hours before bed can alter the brain’s sleep recovery, especially in younger adults. The research found more wake-like brain activity during sleep when caffeine is used in the evening, potentially hindering both mental and physical restoration. For Thailand’s coffee- and tea-loving society, these findings raise timely questions about late-day caffeine and its impact on well-being.

In Thailand, iced coffee and bubble tea after dinner are common choices for students and professionals burning the midnight oil. The study, published in Nature Communications Biology in 2025, indicates that even moderate evening caffeine can noticeably change sleep rhythms, keeping the brain more alert and less restorative. The effect is strongest among people in their 20s due to age-related differences in brain chemistry.

Recent research has drawn urgent attention to the potential risks of herbal and dietary supplements widely consumed for health and wellness, warning that millions—including many in Thailand—may be unwittingly exposing themselves to deadly liver damage. A growing body of evidence now connects familiar ingredients found in kitchen spice racks and health food aisles to a rising incidence of liver toxicity and even liver failure requiring transplantation (Yahoo Lifestyle; PMC).

Herbal supplements have gained popularity in both Western and Asian countries, promoted as “natural” alternatives to conventional medicine that promise everything from better immunity to weight loss. In Thailand, where traditional remedies including turmeric, green tea, and herbal blends play an intrinsic role in health culture, this trend is particularly pronounced (PMC). Yet experts increasingly warn that natural does not always mean safe—especially at high doses or when consumed without medical oversight.

A wave of new research highlights serious risks from herbal and dietary supplements widely used for wellness. Millions, including many in Thailand, may be exposed to dangerous liver injury or even liver failure. Studies link familiar ingredients—often found in kitchen spice racks and health stores—to increasing cases of hepatotoxicity and, in some instances, transplant-needed liver damage.

Herbal supplements have surged in popularity across Western and Asian markets, promoted as natural solutions for immunity, weight control, and vitality. In Thailand, traditional remedies—turmeric, green tea, and blend formulas—are deeply embedded in daily health practices. Yet experts warn that “natural” does not automatically equal safe, especially at high doses or without medical guidance.

Bipolar disorder, a complex mood disorder marked by dramatic oscillations between depression and mania, affects an estimated 40 million people worldwide. It is a condition that not only tests individuals’ emotional resilience but also challenges the medical community in its search for effective, personalized treatments. In a recent episode of NPR’s podcast Short Wave, a renowned psychiatry professor from Johns Hopkins School of Medicine—herself living with bipolar disorder—opened up about her diagnosis, daily management, and the latest advancements in treatment. Her dual role as scientist and patient offers a rare, deeply personal, and scientific insight into a condition that remains stigmatized and often misunderstood in many societies, including Thailand.

A growing body of research is overturning the idea that transient ischemic attacks (TIAs) are harmless. New findings indicate that the effects of a mini-stroke can linger for months or even years, including persistent fatigue, cognitive changes, and an elevated risk of future strokes and heart problems. For Thai patients and the healthcare system, these insights call for faster action, ongoing support, and stronger follow-up care.

For decades, TIAs were described as brief disruptions of blood flow to the brain that serve as warning signs for a stronger stroke. Once symptoms like slurred speech, weakness, or vision loss resolved, people could resume daily life. But recent studies from 2024 and 2025 challenge this comforting narrative. They show that the aftermath of a TIA may undermine quality of life long after symptoms vanish.

A groundbreaking new study from the University of Montreal has revealed that caffeine, the world’s most widely consumed stimulant, tangibly disrupts the brain’s recovery during sleep—especially in younger adults. The researchers found that consuming caffeine in the hours before bedtime leads to more complex, “wake-like” brain activity at night and could hamper both mental and physical restoration, raising crucial questions for Thailand’s coffee- and tea-loving society regarding nighttime caffeine consumption and its impact on well-being (Neuroscience News).

A major U.S. study shows alcohol-related cancer deaths have nearly doubled over the last three decades. The findings come as Thailand’s drinking patterns shift, prompting public health officials to consider stronger prevention measures. Research from a leading cancer center highlights alcohol as a significant carcinogen responsible for thousands of deaths each year worldwide, reinforcing guidance from global health authorities.

Alcohol increases cancer risk even at moderate levels. The International Agency for Research on Cancer first classified alcoholic beverages as a Group 1 carcinogen in 1988, and the World Health Organization has long maintained that there is no completely safe amount of alcohol. In the United States, researchers estimate that alcohol contributes to tens of thousands of cancer cases and related deaths annually, making it a major preventable cause of cancer after tobacco and obesity.

A growing body of new research is turning long-held assumptions about “mini-strokes” upside down, revealing that the effects of transient ischemic attacks (TIAs) may linger far longer than previously thought. Once regarded as brief episodes with symptoms that disappear within a day, these transient strokes are now understood to pose significant long-term health risks—including persistent fatigue, cognitive decline, and an elevated risk of subsequent strokes and cardiovascular events. As experts warn against taking a TIA lightly, the implications for Thai patients and the healthcare system are profound, demanding heightened awareness, rapid intervention, and ongoing support.

A newly released study by University of California San Francisco has uncovered compelling evidence that regular cannabis use, whether smoked or eaten as edibles, poses significant risks to cardiovascular health—on par with those seen in tobacco smokers. The findings, published in JAMA Cardiology on May 28, hold broad implications for communities worldwide, including Thailand, where cannabis reform remains a subject of careful debate and rapid market growth.

The research is particularly significant given that Thailand became the first Asian nation to decriminalise cannabis in 2022, sparking a “green rush” of dispensaries, edible products, and wellness treatments across the country. However, as debates over the benefits and drawbacks of cannabis legalization intensify, the new UCSF data brings overdue scientific scrutiny to the long-term health implications for the Thai public.

A controversial wellness trend is gaining attention: therapeutic plasma exchange (TPE) as a potential anti-aging intervention. While some early studies hint at biological age reduction, Thai health experts urge careful interpretation and emphasize proven medical guidelines.

A recent clinical trial published in Aging Cell explored whether replacing a person’s plasma could slow aging, even in healthy older adults. In this study, 42 volunteers averaging 65 years old underwent several plasma exchanges over three to six months. Researchers reported changes in blood markers that suggested a slowing of biological aging by up to about 2.6 years in some participants. The work, supported by Circulate Health and conducted with aging researcher Dr. Eric Verdin, has sparked global interest, including among wellness-minded readers in Thailand where longevity traditions are strong.

A growing body of research warns that the habits we form in our late 30s and early 40s can set the trajectory for long-term health. Unhealthy choices during ages 36 to 46 are linked to higher risks of cancer, heart disease, and earlier mortality. While youth may feel forgiving, the cumulative effects of lifestyle choices become harder to reverse as people approach middle age. This decade is a turning point for personal well-being and public health.
