Regular sun exposure is beneficial for vitamin D levels from "summary" of The Vitamin D Solution by Michael F. Holick Ph.D., M.D.
Regular sun exposure is essential for maintaining adequate levels of vitamin D in the body. When our skin is exposed to sunlight, it produces vitamin D from a cholesterol precursor. This process occurs in the skin's epidermis and is dependent on ultraviolet B (UVB) radiation from the sun. The amount of sun exposure needed to produce enough vitamin D varies depending on factors such as skin pigmentation, geographic location, time of day, season, and the use of sunscreen. Generally, it is recommended to expose arms and legs to the sun for about 5-30 minutes, a few times a week, during peak sunlight hours. It is important to note that excessive sun exposure can lead to skin damage and increase the risk of skin cancer. Therefore, it is crucial to strike a balance between getting enough sun exposure for vitamin D production and protecting the skin from harmful UV radiation. For individuals who are unable to get enough sun exposure due to factors like living in regions with limited sunlight or having occupations that require staying indoors, vitamin D supplements may be necessary. These supplements can help maintain optimal vitamin D levels in the body and prevent deficiency-related health issues.- Regular sun exposure is a natural and effective way to boost vitamin D levels in the body. By understanding the importance of sunlight in vitamin D production and taking necessary precautions, individuals can ensure adequate levels of this essential nutrient for overall health and well-being.
