As sunlight in Thailand blazes year-round, questions often arise about how much exposure is necessary to support healthy vitamin D levels. New research and updated guidelines released in 2024–2025 reveal that the answer is more nuanced than previously thought, with recommendations balancing the benefits of vitamin D synthesis against the risks of skin damage. Understanding this balance is crucial for Thai residents, who, despite living in a tropical climate, are not immune to vitamin D deficiency.

As Thailand braces for another sweltering summer, a growing international trend has caught the attention of both beauty enthusiasts and health experts: applying deodorant not just to armpits, but to various body areas prone to sweat and odor. A recent discussion in Slate, reflecting personal experiences with using spray deodorant on clothes and across the body, prompts the question—should Thais embrace this expanding application, and is it safe?

The growing popularity of “whole-body deodorants” is more than a passing fad. Major brands such as Dove and Lume have rolled out products specifically marketed for use on more sensitive or “non-traditional” areas—feet, the back, under the breasts, and even the groin—claiming satisfaction and safety for users seeking comprehensive odor control (CNN, Rolling Stone). This shift follows changing consumer hygiene habits in the global north, with the United States seeing a spike in sales of such products since 2024 (Forbes).

Long revered for its golden blooms and gentle healing touch, Calendula officinalis—commonly known as pot marigold—holds a cherished place in both gardens and herbal medicine cabinets worldwide. Across continents and centuries, this humble flower has played a starring role in soothing wounds, calming inflamed skin, and much more. Modern science is now peeling back the petals of these traditions, revealing a story where ancient wisdom and contemporary research harmoniously intersect—a tale with both rich history and real-world potential for health-conscious readers seeking safe, effective, and culturally resonant remedies.

Staying fit with sensitive, easily irritated skin might sound like an Olympic challenge, but new research and expert advice show that people with eczema can still reap the rewards of exercise—if they sweat-smart. With atopic dermatitis now affecting an estimated 245 million people globally and up to 10% of Thai children according to global epidemiological data (Wikipedia: eczema), the question of how to safely integrate exercise into daily life has real consequences for personal health and quality of life across the country.

A newly highlighted dietary supplement is making waves in the health community after US media reports touted its potential to prevent cancer, improve heart health, and slow skin aging. Reported by the New York Post as the “wonder supplement you’ve never heard of,” this compound is rapidly gaining traction, raising questions around its scientific basis, practical benefits, and implications for a health-conscious Thai public. As more consumers seek accessible, natural ways to bolster long-term health, understanding the actual science behind such claims is essential.

Nestled among the colorful stalls of Thai fresh markets, few fruits are as beloved or as culturally significant as the green-skinned citrus known locally as ส้มเขียวหวาน (som kiao wan), or more widely as the tangerine or mandarin orange. While its sweet, juicy flesh is a popular snack across Thailand, it’s the sun-dried peel—often overlooked in the West—that has woven itself into the fabric of both culinary and traditional medicinal practices in Thai society. Today, as scientific research probes the ancient wisdom of herbal remedies, the humble tangerine peel emerges as a fascinating protagonist at the intersection of culture, nutrition, and pharmacology.

Across verdant fields and rural homesteads in Thailand, the humble shrub known as ชุมเห็ดเทศ (Chum Hed Thet), or Cassia alata, has for centuries been regarded by communities as a botanical guardian—renowned for its vibrant golden-yellow flowers and, more significantly, as a stalwart remedy for skin ailments and digestive woes. As tradition finds intersection with contemporary medical research, the remarkable journey of this “ringworm bush”—as it’s known for one of its most common applications—embodies the bridge between ancestral healing and modern science, raising intriguing questions for health-conscious Thais today.

The debate over whether premium-priced or budget-friendly vitamin C serums deliver optimal skin benefits continues to captivate skincare enthusiasts globally. A recent review by Wirecutter, highlights intriguing aspects that explain the stark price disparities between products, while offering recommendations in both categories.

Vitamin C, often revered for its skin-brightening and anti-aging properties, presents formulation challenges due to its notorious stability issues. This stability influences the efficacy of the serum, as noted by dermatologist Mina Amin. A prime example is the high-end SkinCeuticals C E Ferulic, distinguished by its patented stabilization method which enhances both solubility and longevity of the active ingredients. Senior staff writer Rory Evans describes vitamin C as a “diva ingredient,” requiring specific conditions for optimal absorption and effectiveness.
