As Thailand grapples with one of its hottest years on record, new research and expert guidance underscore the life-threatening dangers of exercising or playing sports in extreme heat—a warning that comes as the country continues to experience lingering heatwaves and high humidity. Health professionals are urging community members, particularly athletes, students, and outdoor workers, to take heightened precautions after scientists warn that the body’s ability to safely cool itself becomes severely compromised in such conditions (ABC News).

Thailand is experiencing record heat and high humidity, raising the risk of dangerous heat illness for anyone outdoors. Health professionals warn that exercising, sports, and outdoor work during extreme heat can overwhelm the body’s cooling system, especially in sticky humidity. Local officials stress heightened precautions as heatwaves persist across many regions.

The issue hits Thai communities hard. In April, temperatures in parts of the country climbed into the mid-40s Celsius, one of the region’s hottest episodes in years. Public health advisories from the Thai Meteorological Department urge residents to limit strenuous outdoor activity during peak heat and to seek shade and hydration. These warnings align with broader patterns of rising heat in Southeast Asia, shaping everyday life in Bangkok, the North, and the Northeast.

A new international study questions two decades of climate pledges in tourism, showing the sector’s progress toward reducing emissions has been limited. Conducted by researchers at Linnaeus University in Sweden and the University of Waterloo in Canada, the analysis reviews major climate declarations since 2003 by governments and tourism bodies. Although commitments are plentiful, concrete emissions cuts remain elusive. For Thailand, a top global travel destination, the findings carry urgent implications as the sector drives growth while facing growing demands for environmental responsibility.

A landmark international study has found that despite twenty years of climate pledges, the global tourism industry has made scant progress towards reducing its greenhouse gas emissions, calling into question the sector’s commitment and strategies for climate action. The research, carried out by teams at Sweden’s Linnaeus University and Canada’s University of Waterloo, analyzes the effectiveness of climate declarations from leading tourism organizations and governments since 2003. The findings reveal that while climate commitments abound, meaningful results—especially in terms of emissions reductions—remain elusive, raising urgent concerns for countries like Thailand where tourism is a national economic pillar and environmental sustainability is increasingly central to policy and public debate (Skift).

A dramatic new discovery reveals a sunken world buried under the ocean floor, dating roughly 140,000 years. Researchers describe an ancient ecosystem packed with megafauna and what may be a previously unknown species. The finding, highlighted by international science outlets, offers rare insights into prehistoric life and could reshape our understanding of migrations during major climate shifts.

For Thai readers, the news resonates with Southeast Asia’s submerged landscapes. The Gulf of Thailand and the broader Sundaland region were once land bridges that connected the Malay Peninsula with Borneo and Sumatra. These landscapes likely hosted diverse ecosystems and played a role in early human dispersals. The discovery invites Thailand to reflect on its own underwater heritage and the relevance of ocean science to national environmental policy and education.

A groundbreaking archaeological discovery has brought to light evidence of a 140,000-year-old “sunken world” hidden beneath the ocean floor, astonishing scientists with its trove of ancient megafauna and what appears to be an entirely missing species. This revelation, detailed this week in the international science news, offers rare insights into prehistoric life and has the potential to rewrite our understanding of human and animal migration during shifting climate epochs.

The significance of this find resonates well beyond the realm of pure archaeology. For Thai readers, it is a vivid reminder of Southeast Asia’s own submerged landscapes, such as the Sundaland region now beneath the Gulf of Thailand—an area believed to be a cradle of early human migration and biodiversity during the Last Glacial Maximum. These submerged worlds hold clues to the profound transformations driven by past climate events, informing Thailand’s ongoing dialogue about environmental change, ocean conservation, and regional prehistory.

Thailand is confronting a growing public health challenge as outbreaks of dengue, chikungunya, and Zika affect communities and the nation’s thriving tourism sector. New research shows these viruses, common in tropical climates, are becoming more entrenched, stressing healthcare systems and prompting urgent discussions on protecting residents and visitors during peak travel season. These findings from reputable infectious disease journals fuel the debate on how Thailand can safeguard people and sustain tourism.

A new wave of alarm is sweeping the global health community after research revealed that a severe shortage of omega-3 fatty acids threatens the well-being of millions around the world, including in Thailand. The findings, published in the journal AJPM Focus and led by a team at Case Western Reserve University, underscore a rapidly growing gap between dietary needs and omega-3 availability—a situation with stark health implications for populations who increasingly rely on modern, industrialized food systems. The research warns that 85% of the world’s population is not receiving sufficient omega-3 in their diets, a deficiency that can contribute to elevated risks of chronic diseases and developmental disorders (scitechdaily.com).

A new global alert warns that a severe shortage of omega-3 fatty acids could affect millions, including people in Thailand. Research led by Case Western Reserve University and published in AJPM Focus highlights a widening gap between dietary needs and available omega-3 sources. The study suggests that a large portion of the world’s population does not get enough omega-3s, raising concerns about heart health, brain development, and inflammatory conditions. Data from international health research indicates that 85% of people may be deficient, underscoring the urgency of addressing nutrition in modern, industrialized food systems.

Allergy season is arriving earlier and lasting longer for Thai residents as climate change drives higher pollen counts. While much of the recent coverage originates in the United States, experts warn that Bangkok and other Thai cities are experiencing similar trends, with more days of uncomfortable symptoms like itchy eyes, sneezing, and nasal congestion.

Why this matters for Thailand. Allergic rhinitis, commonly known as hay fever, affects a growing share of the population worldwide and among Thais, particularly in urban areas. The daily impact goes beyond discomfort—school, work, and family activities can be disrupted by persistent symptoms. New research indicates climate and environmental conditions are extending and intensifying pollen seasons. A healthy urban Thai lifestyle now requires awareness of air quality and pollen forecasts.

As Thailand moves from the rainy season into hotter months, many residents reach for tissues with uncertainty. Are persistent sneezes, sniffs, and scratchy throats signs of a lingering cold or reactions to rising pollen? Global research shows allergy seasons are starting earlier and lasting longer due to climate change, making the distinction more important for urban Thais facing air pollution and dense greenery.

The overlap between cold and allergy symptoms is real. Nasal congestion, runny nose, sneezing, and fatigue appear in both conditions, which can lead to misdiagnosis and inappropriate treatment. A senior physician from a major medical center notes, “People often confuse the two. Nasal stuffiness and sneezing occur in both.” With pollen seasons intensifying, Thai doctors warn that managing this issue now extends well beyond a single season.

Fears of humanity’s extinction may sound far-fetched, but scientists are warning that global birth rates are falling so fast, some populations could eventually disappear unless women have more children. According to recent research synthesized by experts and highlighted in a much-discussed feature on population trends, the world could see dozens of countries’ populations shrinking by 2100 due to persistently low fertility rates—a phenomenon with profound implications for economies, societies, and the future of human civilization itself (Daily Mail).

As Thailand’s wet season transitions into the hot months, many residents find themselves reaching for tissues—uncertain whether their persistent sneezes, sniffles, and scratchy throats are signs of a lingering cold or responses to the rising pollen count. With research indicating that allergy seasons globally are starting earlier and lasting longer due to climate change, understanding the difference between allergies and the common cold has never been more important—especially for those living in Bangkok and other urban centres prone to increasingly severe air pollution and dense greenery (theguardian.com).

A shrinking population is no longer a distant possibility—it is unfolding in real time. Global fertility rates have fallen to levels that could see dozens of countries experience population declines by 2100. This trend carries wide-ranging implications for economies, social systems, and daily life in Thailand and beyond.

Thailand already confronts one of Asia’s fastest-ageing populations. Officials warn that without a rise in the national fertility rate, fewer young people may be available to support an increasing elderly population, straining healthcare, pensions, and the labor market. The global replacement level—about 2.1 children per woman to keep population stable—has already fallen below 2.0 in many developed countries, including Thailand.

A recent analysis by leading nutrition researchers has sounded an alarm about a growing deficiency of omega-3 fatty acids worldwide, a shift that experts warn may have broad and potentially lasting consequences for public health. With more than 85% of surveyed populations now failing to meet recommended omega-3 intake, researchers say modern diets, environmental change, and ocean pollution have dramatically undermined access to this essential nutrient (Earth.com).

Omega-3 fatty acids—long heralded for their roles in heart, brain, and eye health—are a cornerstone of a balanced human diet. For Thai readers, who live in a nation rich in seafood traditions, these findings raise new questions about the sustainability of trusted food sources and the best strategies to promote lifelong wellbeing. Nutrition scientists highlight omega-3 as crucial to preventing cardiovascular disease, supporting memory and mood, and facilitating the healthy function of cells throughout the body. According to a research scientist with Case Western Reserve University’s Department of Population and Quantitative Health Sciences, “This has serious and widespread health implications.”

A surprising alert from recent coverage suggests the Antarctic ice sheet has grown for the first time in decades. The report challenges the long-standing view of relentless polar ice loss and prompts experts to reexamine how ocean currents, weather patterns, and snowfall interact with global warming. For Thailand, where flood risk remains among the highest worldwide, the development raises questions about longer-term sea-level trends and regional preparedness.

Continued satellite observations have documented complex dynamics in Antarctic ice. While long-term data show a global warming trend and significant ice loss in some regions, researchers caution that short-term fluctuations do not overturn the overarching pattern. In particular, scientists note that ocean circulation changes, regional climate variability, and episodic heavy snowfall can temporarily influence ice behavior. As a result, robust conclusions require decades of consistent data, not just isolated periods of growth.

In a surprising shift, the Antarctic ice sheet has reportedly expanded for the first time in decades, according to a recent article by The Daily Galaxy (dailygalaxy.com). This development marks a significant reversal from the enduring narrative of relentless polar ice loss and has triggered widespread discussion in the scientific community about the complexities of climate change, ocean currents, and global weather patterns.

For years, research and satellite observations have documented a steady decline in both the Arctic and Antarctic ice sheets, with implications for rising sea levels and extreme weather events worldwide. Thailand, a country consistently ranked among the world’s most vulnerable to climate change-driven flooding, has closely monitored these polar trends. News of an expanding Antarctic ice sheet, therefore, raises critical questions: Is this a fleeting anomaly or a sign of deeper shifts in Earth’s climate system? And what might this mean for global strategies to address rising seas and environmental crises?

Flying abroad brings excitement for many Thais, whether for work, study, or leisure. But turbulence can trigger anxiety, leaving passengers gripping armrests and silently wishing for a smoother ride.

Insights from seasoned flight attendants demystify this aviation reality and offer actionable guidance.

For many Thais, the thought of flying abroad—whether for business, study, or leisure—evokes excitement, but also anxiety. This is especially true when a smooth journey is suddenly interrupted by turbulence, leaving passengers gripping their armrests and silently chanting “สาธุ” (sa-thu) for safe passage. A new feature published on HuffPost, “How To Calm Anxiety During Turbulence, According To Flight Attendants” (source), brings comfort by distilling practical, expert-backed strategies straight from the world’s most seasoned flyers.

As the annual tick season approaches in North America, a rare but dangerous virus is attracting mounting attention: Powassan virus. While this tick-borne illness remains uncommon, recent research and rising case reports point to growing concerns that reverberate beyond Western borders—and carry valuable warnings for Thailand as well.

Powassan virus, primarily transmitted by blacklegged ticks, has been recognized as one of the most serious tick-borne diseases in the United States, despite its rarity. Last year, Minnesota reported a record 14 cases, the highest count since 2008 when official recordkeeping began. According to Minnesota Department of Health data, while most years saw fewer than five cases, a slow but concerning uptick has prompted both local and national action. “The risks are relatively low, however, all the tick prevention that you would do to keep yourself from getting one of those more common diseases will also help keep you safe from getting Powassan,” Elizabeth Schiffman, an epidemiologist supervisor at the Minnesota Department of Health, emphasized in a recent interview (Star Tribune).

A rare but serious tick-borne virus is drawing global attention as tick season begins in North America. Powassan virus, while uncommon, has sparked concern among researchers and public health officials for its potential impact beyond its initial hotspots—and for what it could teach Thailand about preparedness and surveillance.

Powassan virus is mainly carried by blacklegged ticks. It is considered one of the most dangerous tick-borne diseases in the United States, even though cases remain relatively few. Last year, Minnesota reported a record 14 cases, the highest since nationwide recordkeeping began in 2008. Data from Minnesota’s health authorities shows a gradual uptick, prompting both local and national responses. An epidemiologist from the Minnesota Department of Health notes that standard tick prevention measures also reduce Powassan risk, underscoring the universal value of protective practices.

A major international study warns that rising temperatures and higher atmospheric carbon dioxide are increasing arsenic concentrations in rice, Thailand’s everyday staple. The findings, published in The Lancet Planetary Health, suggest that climate change could turn rice into a greater health risk for populations that rely on it for most of their daily calories. This issue resonates across rice-dependent societies, including Thailand, where consumption is deeply tied to culture and livelihood.

Recent insights from the 2025 Oxford LEAP Conference suggest a transformative shift is imminent in how we approach food production and consumption. Paul Behrens, a prominent scholar from the University of Oxford, highlighted the unsustainability of current agricultural practices due to intensifying environmental pressures and global market vulnerabilities. Behrens’ research underscores the primary drivers of this change: agriculture-induced environmental degradation and the compounded threats of climate change, exemplified by extreme weather events such as the extensive floods in Australia earlier this year. Reports from Queensland, one of Australia’s key cattle regions, pointed to significant livestock losses, emblematic of the intensifying volatility in food systems worldwide.
