Tanning Causes Vitamin D Deficiency

Tanning Causes Vitamin D Deficiency

Sunlight is supposed to be good for producing Vitamin D by the skin; however, it seems there can be too much of a good thing. According to a recent research, excessive exposure to sunlight can lower the body’s ability to produce the vital nutrient, reports livemint.com. Researchers in Brazil found that though tanned skin provides coverage against harmful UV rays of the sun, the increase in pigmentation interferes with Vitamin D synthesis in the body, leading to its decrease. “Our findings suggest that skin tanning, which is a natural protection against the harmful effects of UV irradiation, limits the progressive rise in serum vitamin D towards optimal concentrations,” said study author Dr. Francisco Bandeira.
