Regular exercise can prevent a steep winter decline in vitamin D levels, offering an alternative to supplements, according to a new study led by researchers from the University of Bath, University of Cambridge, and University of Birmingham. The findings, relevant for both global audiences and Thailand, provide practical advice for maintaining musculoskeletal and immune health during months with limited sunlight, when the risk of vitamin D deficiency sharply increases (BBC).

A new study led by researchers from the University of Bath, the University of Cambridge, and the University of Birmingham shows that regular indoor exercise can blunt the winter drop in vitamin D. The findings offer a practical alternative to supplements for maintaining bone, muscle, and immune health during months with limited sun exposure, with relevance for global readers and Thai audiences alike.

Vitamin D, often called the “sunshine vitamin,” is essential for bone and muscle strength and immune function. In the United Kingdom, more than 10% of adults are believed to have insufficient vitamin D. In Thailand, research indicates that between 34% and 77% of adults experience deficiency or insufficiency, despite the country’s tropical climate. Urban living, sun avoidance, and air pollution contribute to low levels, making these results particularly meaningful for Thailand.
