We all know that too much sun exposure may increase the risk of skin cancer. In fact, according Green Science, the ultraviolet radiation energy from the sun is so dangerous to our health that the World Health Organization declared it a carcinogen.
However, there is some benefit to sun exposure. That benefit is Vitamin D. To gain this benefit from the sun, individuals should spend time in the sun without sunblock. According to Green Science, most sources state that light-skinned individuals should try to get 10-15 minutes of sun at least three times per week. While darker-skinned individuals could need an hour or more to gain the same amount of Vitamin D due to the presence of melanin which protects against the UV radiation.
