Are there health benefits of exposure to UV radiation?
According to the World Health Organization, brief exposure to UV radiation, about 5-15 minutes twice a week, is beneficial in helping the body produce vitamin D. However, the amount of exposure needed depends on several factors, including where you live, the time of day, and the time of year. UV radiation, in the form of lasers, lamps, or a combination of these devices and topical medications that increase UV sensitivity, are sometimes used to treat patients with certain diseases who have not responded to other methods of therapy. Also known as phototherapy, this method of UV exposure is performed by a trained healthcare professional under the supervision of a dermatologist.
