You are never too old or too young to protect yourself from the damaging effects of UV radiation. It is particularly important to protect infants, children, and teens, since about 80% of lifetime sun exposure is received by age 18. Studies show an increased risk of melanoma is strongly associated with blistering sunburns between the ages of 10 and 19.

The most effective way to protect yourself from harmful UV radiation is to stay out of the sun. Stay indoors or look for shade in the middle of the day when UV radiation is strongest, usually between 10 a.m. and 4 p.m. Seek shade under an umbrella, tree, or other shelter before you need relief from the sun. Try to plan outdoor activities for the early morning or late afternoon, when UV radiation is typically one-third of what it is at midday.

If you are going to be in the sun, cover up! Long-sleeved shirts, long pants, wide-brimmed hats, and sunglasses offer the best protection against UV radiation. If you can't cover up completely, be sure to use a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 15 on all exposed skin.
