Vitamin D health guidance stresses winter sunlight, diet and safe sun exposure

Winter months lower natural sunlight, reducing the body’s primary source of vitamin D. Adequate vitamin D supports calcium absorption for bone health, muscle function, immune response and mood regulation. Health experts recommend five simple habits to maintain levels: seek natural light during outdoor breaks, consume fatty fish such as salmon or sardines, choose fortified dairy or plant‑based products, stay physically active, and consult a professional before using supplements.

Moderate sun exposure also offers health benefits, boosting vitamin D production, strengthening immunity and helping regulate sleep. Authorities advise protecting the skin with sunscreen or clothing to avoid damage while enjoying the advantages of sunlight safely.
