Vitamin D in Thailand: Short Sun Breaks, Safe Practices, and Smart Choices for Health
A growing Thai audience faces a familiar dilemma: how to get enough vitamin D from sunlight without elevating skin-cancer risk. A recent synthesis of scientific findings shows that brief midday sun exposure can meet daily needs for many adults, but safety and lifestyle factors determine the real balance between sun and health.
In Thailand’s sun-rich climate, many people still miss out on vitamin D due to modern routines—long indoor hours, dense urban living, and beauty standards that favor lighter skin. Health experts emphasize that a few minutes of direct sun around midday, with a portion of the body exposed, can help most adults meet daily vitamin D targets. The emphasis, however, is on moderation and protection from ultraviolet radiation. Research summarized for Thai readers suggests that 10–30 minutes of sun exposure, with about 25% of the skin exposed on arms and legs, often suffices in spring and summer. By contrast, in winter or higher latitudes, longer exposure may be necessary to achieve the same effect. For Thailand’s latitude, the sun is generally favorable, but daily habits decide the outcome.
