Most people enjoy spending time outdoors but too much time in the sun can cause problems later.
People with fair skin, freckles and red or blond hair are most at risk but even those who tan easily need to be careful. Avoid being outside from 10 am to 3 pm when the sun's rays are the strongest. Wear protective clothing such as long sleeves and a hat to cover your face. Use a sun screen with a sun protection factor of at least 15. Reapply it often, especially after swimming or perspiring.
