Minimize sun exposure especially during the peak sun hours of 10 a.m. to 3 p.m., when the sun's rays are most intense.

Apply a sunscreen liberally and frequently and reapply every two hours. An SPF of 15 is recommended. Even on cloudy days, 80% of the sun's rays penetrate the clouds.

Wear appropriate clothing during prolonged periods in the sun, including a wide-brimmed hat, long-sleeved shirt and pants.

Avoid tanning parlors and sun lamps. The ultraviolet rays emitted by these artificial sources are similar to those in sunlight and can cause sunburn, premature aging of the skin and increased risk of skin cancer. Read Next Article
