Vitamin D And Sunlight: How To Know If Your Sun Exposure Is Producing Vitamin D
Sunlight and Vitamin D
21 Jul The danger of overexposure to solar ultraviolet radiation has been widely reviewed since the s due to the depletion of the ozone layer.
Description:People commonly think that if the sun is up and they are outside in the sun, they are going to produce Vitamin D. This is not the case! Yet UVB is reflected and blocked by the atmosphere. The more atmosphere UVB rays have to travel through, the more UVB rays are prevented from reaching the surface of the earth; and the lower the sun is in the sky, the more atmosphere these UVB rays travel through. If the sun is low enough, UVB rays are completely blocked by the atmosphere before they even reach you, and Vitamin D production is not possible.
