Ultraviolet (UV) light has the ability to improve immune responses and promote health, but don’t rush out to sunbathe or purchase UV lamps, warns UB light therapy expert Praveen Arany. Although exposure to small amounts of UV radiation can have beneficial effects, such as vitamin D synthesis in the skin, overexposure can cause serious acute (short-term) and chronic (long-term) health effects.. The good effects are relatively few, but they are essential to a persons well being. The amount of UV exposure a person can receive on their skin or eyes during an 8-hour period varies with the wavelength of the UV radiation. The article describes some effects on human health, aquatic ecosystems, agricultural plants and other living things, and explains how much ultraviolet radiation we are currently getting and how we measure it. Benefits from UV radiation. It is also used to treat skin diseases such as … It may also lower the risk of getting some kinds of cancers such as colon cancer.
