As rainy season intensifies across Thailand, new research and expert advice highlight eight proven ways to reduce mosquito bites – and the diseases they spread. The latest guidance, grounded in entomological science, resonates strongly in the Land of Smiles where mosquitoes are not just a nuisance but a public health threat due to dengue, Zika, and chikungunya. Drawing from the insights of leading pest control professionals and entomologists, the recommendations offer practical steps for Thai households and communities seeking to protect themselves in the months ahead.

Should Thai health enthusiasts reconsider their daily fish oil supplements in favour of krill oil? The question has sparked debate as both products compete for attention in the growing wellness market. Recent research and expert opinion highlight significant similarities and key differences between these two omega-3 powerhouses, leaving many to ponder their best choice for heart, brain, and overall health Verywell Health.

For years, fish oil has been the most popular source of omega-3 fatty acids, hailed for helping to prevent and manage heart disease, high blood pressure, and inflammation. Now, krill oil—derived from tiny crustaceans found in Antarctic waters—is being marketed as a more bioavailable and antioxidant-rich alternative. With Thais increasingly concerned about diet-related illnesses and eager to adopt science-backed preventive health trends, these claims matter deeply. But does the science support making the switch?

Tiny plastic particles, no wider than a human hair, have made their way into an alarming new corner of human biology: the fluids surrounding eggs in women and sperm in men. The latest research, unveiled at the 2025 European Society of Human Reproduction and Embryology conference and published in the journal Human Reproduction, provides the clearest evidence yet of microplastics’ persistent ability to infiltrate the most sensitive aspects of our bodies—raising serious questions about fertility, long-term health, and the true cost of our reliance on plastics (Earth.com; CNN).

As global travel rebounds with unprecedented force, new research warns that the benefits of mass tourism may be shadowed by serious costs—both for beloved destinations and their residents. In 2024, a staggering 1.4 billion people traveled internationally, according to the United Nations World Tourism Organization, accounting for roughly one in six people worldwide. For many communities, this surge has been a mixed blessing: while it has brought economic prosperity, it is also overwhelming town centers, fracturing local cultures, inflating living costs, and jeopardizing the pristine sites that first drew visitors from afar (UNWTO).

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).

As international tourism rebounds to near-historic highs in 2024, destinations across the globe, including Thailand, are grappling with the complex challenge of overtourism. Recent insights published by Deutsche Welle reveal that around 1.5 billion people travelled for leisure last year, marking it as the second busiest year for global tourism ever recorded, surpassed only by 2019 (DW). This surge has reignited urgent debates about the sustainability of tourism, with mounting evidence that unchecked visitor volumes can damage local environments, disrupt daily life, and strain vital infrastructures.

Concern is mounting among global health experts as recent research reveals that cancer-causing chemicals—some even found in so-called ‘eco-friendly’ food containers—are leaching into what we eat. These revelations, emerging from multiple studies and echoed by urgent warnings from toxicologists, suggest that Thai consumers, like people worldwide, may be inadvertently exposing themselves and their families to hazardous substances every time they dine on packaged foods.

Interest in safer, more environmentally friendly packaging has soared in Thailand, with a booming market for biodegradable, compostable food containers accompanying a surge in food delivery and street food consumption. However, new findings indicate that many packaging alternatives still contain or leach synthetic chemicals linked to cancer, such as per- and polyfluoroalkyl substances (PFAS), bisphenols, and phthalates, which are common components in coatings, plastics, and even so-called ‘green’ food wrappers. A major investigation by the Food Packaging Forum identified 189 potential and confirmed mammary carcinogens detected in food contact materials, including items marketed as eco-friendly, raising questions about the true safety of these alternatives (foodpackagingforum.org).

In a significant leap for environmental health research, scientists at the University of California, Riverside (UCR) have developed a new computer language called Mass Query Language, or MassQL, which enables researchers to effortlessly sift through vast chemical datasets to detect previously hidden pollutants. This innovative tool, detailed in a recent Nature Methods journal article, has already led to the discovery of toxic compounds in public water sources that had previously gone unnoticed by traditional detection methods (UCR News).

A recent global study has raised alarm about the widespread use of phthalates—common chemicals found in everyday plastics—linking them to hundreds of thousands of heart disease deaths worldwide. The research, published this week in the journal eBioMedicine by a team at New York University’s Grossman School of Medicine, estimates that in 2018, phthalate exposure contributed to 350,000 cardiovascular deaths, particularly among adults aged 55 to 64 years old. This translates to approximately 13% of heart disease deaths in that age group, underscoring the potential public health threat posed by chemicals commonly used in food packaging, toiletries, toys, and household products [NYTimes].

A wave of urgent scientific warnings has gripped international health and environmental communities as researchers uncover the pervasive contamination of everyday products with “invisible” microplastics—tiny particles of plastic less than five millimeters in size that can easily enter food and drinking water, impacting people after just a single use. This silent invasion, previously believed to be a concern mainly with overused or degraded plastic items, is now recognized as an immediate health issue, requiring both policy responses and personal vigilance, including here in Thailand (Yahoo News).
