The risk of developing skin cancer is related to the amount of ultraviolet radiation you are exposed to over a lifetime, particularly during your childhood and school years.

Have you ever been sunburnt? When you get too much ultraviolet radiation your body releases chemicals that make our blood vessels expand and release fluids. This causes the redness and pain that we call sunburn.

Whenever the UV alert is above 3 you need to protect yourself from the sun. This usually occurs between 10am and 2pm.
