How Much Sun Am I Getting?

Updated May 8, 2019 | Infoplease Staff

Though the amount of UV radiation to which you are exposed varies with the time of day, season, latitude, and altitude, it can also be increased depending on your immediate environment. Clouds actually provide little protection from UV rays, and clouds, water, white sand, concrete, and snow all reflect UV rays and increase exposure. Of course, exposure to the midday sun or for long periods of time is most damaging.
