Being exposed to too many UV rays has been linked to these negative health effects: 1  sunburns. 2  premature skin aging. 3  skin cancer. 4  eye damage. 5  weakening of the immune system.

It can damage your skin even on cool, cloudy days. Sunburn is a radiation burn to the skin. The signs of sunburn can start to appear in less than 15 minutes and skin can turn red within two to six hours of being burnt. It will continue to develop for the next 24 to 72 hours and, depending on the severity, can take days or weeks to heal.
