How does ultraviolet radiation effect us?

UV burns skin. Sunburn is a burn that occurs when skin cells are damaged. This damage to the skin is caused by the absorption of energy from the UV rays. It damages the immune system - over exposure to UV radiation has a harmful suppressing effect on the immune system

UV - B, a higher energy form, causes the most damage to living organisms and materials. Exposure to UV radiation has been linked to many human health problems, including skin cancer. Scientists also indicate that increased exposure to UV - B rays affects the human immune system and causes premature aging of the skin.
