Carbon particles in the air from the burning of fossil fuels, wood, and other materials scatter and absorb UVB rays, diminishing vitamin D production. Short days and clothing that covers legs and arms also limit UVB exposure. Residents of Boston, for example, make little if any of the vitamin from November through February. The further away from the Equator you live, the less vitamin D–producing UVB light reaches the earth's surface during the winter. The liver and the kidneys also participate to make a form of the vitamin that the body can use.Ī number of factors influence a person's vitamin D levels.

It starts when the skin absorbs rays in the invisible ultraviolet B (UVB) part of the light spectrum. The process by which the body makes vitamin D is complex.

The amount of vitamin D a person’s skin makes when they are in the sun depends on many factors, including skin tone, geographic location, weather conditions, time of year, and time of day.Figuring out all the factors that can affect your vitamin D level is complicated. Having little or no sun exposure may put a person at risk for low levels of vitamin D, but too much UV exposure from the sun or artificial sources can increase risk of skin cancers and eye disease. Ultraviolet (UV) rays from the sun can stimulate production of vitamin D in the skin. Schools and businesses may consider adding shade to school grounds and places were people gather outside. Communities can help by ensuring shade is available in public parks. Protect yourself by staying in the shade, wearing protective clothing, and applying and re-applying a broad spectrum sunscreen with a sun protection factor (SPF) of 15 or higher.
