Amid rising global interest and legal reforms surrounding cannabis, recent research is painting a complex picture of its true effects on common health problems such as insomnia, chronic pain, and anxiety. A series of large-scale studies from Australia to the United States highlight encouraging long-term improvements in quality of life for patients with stubborn conditions, but also raise serious caution about potential mental health risks such as paranoia, psychosis, and increased risk of psychiatric disorders.

A large study from Harvard Medical School and Massachusetts General Hospital links certain daytime napping patterns to higher mortality risk. Long naps, irregular schedules, and naps clustered between 11am and 3pm were associated with greater chances of death from any cause, even after adjusting for age, weight, smoking, alcohol use, and nighttime sleep quality. The findings come from tracking over 86,000 adults for eleven years with wearable devices, offering a clearer picture than self-reported sleep data.

Social feeds overflow with tips to “lower cortisol now,” but new research and expert guidance urge Thai readers to view these trends with caution. Promoting coconut water blends, unusual supplements, or essential oils as magic stress cures often lacks credible evidence and can distract from real, sustainable stress management.

In Thailand’s fast-paced urban life, high cortisol is a familiar concern. Modern stressors such as pervasive smartphone use, constant connectivity, and work-life pressures can influence stress responses. Yet medical experts warn against tying everyday changes in appearance or energy directly to cortisol levels. They emphasize that many factors—lifestyle, health status, and mental well-being—shape how we respond to stress, not hormones alone.

Social media platforms are overflowing with hacks and quick-fix promises to “lower cortisol,” but new research and leading experts warn Thai readers that these trending “cortisol cocktails” and other instant suggestions are unlikely to provide the promised relief—or protect us from the real consequences of chronic stress. As digital wellness advice explodes in popularity, claims about the power of coconut water, special supplements, and essential oils to rebalance the body’s stress hormone have become common. Yet, according to the latest investigations, the science tells a more complex, and at times, cautionary story.

A recent news story highlighting a British grandfather’s journey in reversing his pre-diabetes diagnosis through modest lifestyle changes is sparking renewed interest in the global fight against diabetes—a disease affecting millions in Thailand and putting a strain on local health resources. The compelling account, originally reported by Yahoo News, not only offers hope for those in the early stages of diabetes but also reflects emerging scientific consensus that simple, sustainable adjustments can lead to dramatic health improvements.

A recent story about a British grandfather reversing his pre-diabetes through modest lifestyle changes has renewed global and Thai focus on diabetes prevention. This narrative—originating from a widely circulated report—highlights evidence that sustainable, small steps can yield meaningful health gains.

Pre-diabetes means blood sugar is elevated but not yet at diabetes levels. In Thailand and around the world, it affects millions and often goes undetected. Data from Thailand’s public health sources and global estimates show a large population sits on the edge of type 2 diabetes, with serious risks if not addressed. Untreated pre-diabetes increases the likelihood of heart disease, kidney problems, nerve damage, and vision loss.

A new long-acting HIV prevention injection, Yeztugo (lenacapavir), has earned approval from U.S. regulators and promises to curb new infections globally, including in Southeast Asia. Experts say a biannual shot could overcome adherence hurdles tied to daily PrEP pills, potentially speeding progress against HIV/AIDS. Yet questions about cost, availability, and implementation loom—especially for middle-income countries like Thailand.

In Thailand, HIV remains a serious public health and social issue. Despite gains in prevention and treatment, about 5,000 new infections occur each year, according to the Department of Disease Control and data from UNAIDS in Thailand. While daily PrEP pills such as Truvada and Descovy are available, adherence is often hindered by stigma, affordability, and the burden of daily dosing. Yeztugo aims to change this with a simple regimen: two oral doses followed by a semiannual injection.

A groundbreaking HIV prevention injection, Yeztugo (lenacapavir), recently approved by the U.S. Food and Drug Administration, promises to significantly reduce new infections worldwide, including in Southeast Asia. Experts say this long-acting, twice-yearly shot could help overcome challenges associated with daily HIV-prevention pills, potentially transforming the fight against HIV/AIDS. However, questions about accessibility, cost, and implementation remain—issues of particular concern for middle-income countries like Thailand.

For Thais, HIV remains a chronic social and public health issue. Despite major progress in prevention and treatment, approximately 5,000 new HIV infections occur annually, according to the Department of Disease Control and UNAIDS (UNAIDS Thailand). While daily pre-exposure prophylaxis (PrEP) pills—such as Truvada and Descovy—have been available, adherence is often hindered by stigma, cost, and the burden of taking medicine every day. Yeztugo aims to change that with a simple regimen: two oral doses followed by a subcutaneous injection every six months.

A wave of new research is drawing unprecedented connections between marijuana use and serious cardiovascular risks, overturning widely-held beliefs that cannabis is relatively harmless. Large-scale studies published in mid-2025 point to a significantly increased risk of heart attack, stroke, and cardiovascular death among users of marijuana—a finding that experts caution should inform personal and public health choices in Thailand and worldwide (The New York Times; Fox News; Virgin Islands Consortium).

As marijuana use undergoes rapid normalization, with legal medical and recreational access expanding across the world, researchers warn that its cardiac dangers are becoming clearer and more urgent. In Thailand, where medicinal cannabis was legalized in 2022 and recreational use remains in legal limbo, these findings arrive as lawmakers and public health officials debate the way forward in marijuana regulation and education (CNN).

New research released in 2025 strengthens concerns about marijuana’s impact on heart health. Large-scale studies show cannabis users face higher risks of heart attack, stroke, and cardiovascular death compared with non-users. These findings arrive as Thailand debates cannabis regulation and public health messaging amid growing access to medical cannabis and ongoing questions about recreational use.

Recent analyses indicate that marijuana’s active compounds, especially THC, can affect blood vessels, heart rate, and blood pressure. In Thailand, where medicinal cannabis was legalized in 2022 and recreational use remains unresolved, experts say the new evidence underscores the need for careful policy making and consumer education. Public health officials note that the tone of messaging around cannabis—often framed as “natural medicine”—must now include clear information about cardiovascular risks.

A comprehensive review of knee osteoarthritis shows that knee braces are among the most effective non-surgical options for reducing pain and improving mobility. The analysis covered nearly 10,000 participants across 139 randomized trials, offering an evidence-based update for managing knee pain in Thailand and worldwide. While braces provide significant relief, experts emphasize that regular exercise and a healthy weight are essential to slow disease progression and sustain improvements.

Knee pain is a leading concern for Thai adults, especially those over 50. Thailand’s Ministry of Public Health highlights osteoarthritis as a major source of mobility limitations among older populations. Patients traditionally receive a mix of treatments—from medications and physical therapy to injections or surgery—yet questions remain about which methods work best in real life.

A major new scientific review has found that knee braces are among the most effective ways to alleviate pain and improve mobility for people suffering from osteoarthritis—a degenerative joint disease that affects millions in Thailand and worldwide. The study, which analyzed the results from nearly 10,000 participants across 139 randomized controlled trials, provides a much-needed evidence-based update to common knee pain management practices and offers valuable guidance for the many Thais living with this disabling condition. Despite bracing’s demonstrated benefits, medical experts emphasize that regular exercise and maintaining a healthy weight remain critical for both symptom relief and slowing disease progression.

A major international analysis finds that regular cannabis use may pose significant heart risks, at times rivaling or exceeding those associated with cocaine. The study, published in Heart, aggregates data from thousands of studies and millions of individuals to reassess cannabis’s cardiovascular safety. For Thailand, where cannabis policy is evolving rapidly, the findings carry urgent implications for users, health professionals, and policymakers.

Historically, cannabis has been portrayed as a natural remedy with relatively mild side effects. In Thailand, cannabis products are increasingly present in wellness venues and traditional medicine circuits. The new evidence suggests that regular cannabis use can increase the likelihood of heart attack, stroke, and fatal cardiovascular events. Scientists emphasize that these risks persist even after accounting for tobacco, alcohol, and other substances, underscoring the complexity of cannabis’s impact on the heart.

A groundbreaking new study has sent shockwaves through the medical and public health communities by revealing that cannabis use could be more dangerous for the heart than cocaine. The research, published recently in the esteemed journal Heart, synthesizes data from over 432 million individuals and challenges widespread perceptions about the safety of cannabis, especially as legalization expands globally. For Thailand, where decriminalization and policy debates about cannabis are accelerating, the study’s findings carry urgent implications for users and policymakers alike.

A groundbreaking small study reported this week suggests that a single dose of psilocybin—the active compound in so-called “magic mushrooms”—may provide significant antidepressant effects that last at least five years for most patients. This finding, detailed in Live Science, could herald a new era in mental health treatment strategies, especially for those battling persistent depression.

The importance of this research resonates across the globe and holds particular interest for Thailand, where mental health care has experienced increased public attention and evolving social attitudes in recent years. Historically, treatment protocols for depression in Thailand have primarily relied on psychotherapy and long-term pharmacological interventions, yet many patients continue to suffer relapse or side effects. Emerging research on psychedelic-assisted therapy, such as this recent study, offers hope for more durable solutions and challenges existing stigmas surrounding mental health and controlled substances.

A recent, small study indicates that a single dose of psilocybin—the active compound in magic mushrooms—could provide significant antidepressant effects for years. The findings, published and discussed in science coverage, point to potential breakthroughs in how depression is treated, particularly for patients who struggle with relapse.

The research resonates globally and holds particular relevance for Thailand, where mental health care has gained public attention in recent years. Traditional Thai treatment for depression has relied on psychotherapy and long-term medications, but many patients still experience relapse or adverse effects. Emerging evidence on psychedelic-assisted therapy offers hope for more durable solutions and invites thoughtful discussion about how society views controlled substances and mental health care.

A wave of recent research is renewing the debate over whether diet soda can beat water for some people seeking to lose weight. While some studies report greater weight loss with artificially sweetened beverages in structured programs, experts urge caution and emphasize broader dietary patterns. The discussion matters for Thailand, where rising obesity and metabolic disease pose public health challenges.

The question is not just a social media talking point. For millions of Thais, the choice between diet drinks and plain water intersects with rising obesity, diabetes, and heart disease. Public health officials in Thailand have already introduced sugar taxes and promoted low-calorie options, underscoring the need for clear consumer guidance in a market saturated with both regular and diet beverages.

A series of recent studies has reignited the debate over whether drinking diet soda could be more effective than water in helping some people shed extra kilos, with researchers and nutritionists weighing in on the controversial claim. The renewed interest comes after social media buzz and resurfaced research suggesting that people drinking artificially sweetened beverages daily—rather than water—lost significantly more weight over the course of a year. The findings, however, have sparked both optimism and concern among health experts, with implications that extend to Thailand’s growing public health challenges associated with obesity and metabolic disease.

A major new study from Harvard University’s School of Public Health highlights a familiar ritual—drinking coffee—hinting that caffeinated coffee may support healthier aging in women. Presented at the American Society for Nutrition’s annual conference, the findings could influence discussions on diet, wellness, and longevity for women worldwide, including in Thailand.

Researchers followed more than 47,000 women for three decades, monitoring health as they aged. They found that women who consumed the highest amounts of caffeinated coffee had about a 13% greater chance of aging healthfully—that is, reaching age 70 or older without major chronic diseases or cognitive decline. The study’s lengthy observation period lends credibility, as acknowledged by nutrition and medical experts. Data from the Nurses’ Health Study underpins these conclusions and has been interpreted by health professionals as meaningful when considered alongside other lifestyle factors.

Many older Thais have consistently sought out vaccinations for diseases like shingles, influenza, and pneumonia—a strategy that is increasingly validated by a wave of new international research that also carries critical implications for the Kingdom’s rapidly aging society. These findings not only reinforce the wisdom of vaccine compliance among Thailand’s elderly populations but reveal surprising new benefits, including a reduced risk of dementia, according to recent studies published and reported globally, most notably in a major New York Times article.

A growing body of research sheds new light on pelvic floor dysfunction (PFD), a health condition now recognized as impacting up to half of all women at some point in their lives. According to a recent report in The Conversation, PFD is not only common after pregnancy and childbirth but is increasingly affecting physically active women and is a more significant issue than previously believed (The Conversation). This revelation prompts vital questions for Thai readers about prevention, early detection, and the importance of pelvic health for daily life and wellbeing.

A new wave of research from Harvard University’s School of Public Health shines a bright spotlight on a beloved daily ritual—drinking coffee—suggesting that women who sip caffeinated coffee may enjoy a significant boost toward healthy aging. The findings, presented this June at the American Society for Nutrition’s annual conference, are poised to add new dimensions to conversations about diet, wellness, and longevity for women around the world—including here in Thailand.

A growing body of research shows pelvic floor dysfunction (PFD) affects up to half of all women at some point. The Conversation reports that PFD is not only common after pregnancy but also increasingly affects physically active women. For Thai readers, this raises questions about prevention, early detection, and daily wellbeing.

PFD describes weakened or poorly functioning muscles and ligaments in the lower pelvis. Symptoms range from urinary incontinence to pelvic organ prolapse and discomfort during intimacy. As exercise trends rise in Thailand—HIIT, CrossFit, and long-distance running—health professionals warn that symptoms can be more common than many expect. Data from recent studies indicate that women who engage in high-intensity exercise may experience symptoms at a notably higher rate. Pelvic health, therefore, matters for all women, not just those who have given birth.

A growing body of international research reinforces a simple truth many Thai seniors already practice: vaccines protect more than you might expect. Beyond preventing shingles, flu, and pneumonia, new studies suggest vaccines may also lower dementia risk. This has important implications as Thailand’s population ages rapidly.

Across the globe, older adults are increasingly receptive to vaccination. In Thailand, the Ministry of Public Health reports consistently high influenza vaccine uptake among people over 65, contributing to fewer deaths from preventable diseases during flu seasons. Recent analyses add depth, suggesting vaccines may offer broader protection, including cognitive benefits.
