Sun Safety (1220)

New research suggests sunscreen alone isn't protective enough from the sun's rays. Hats, along with sunscreen, may be the best defense against skin cancer. For instance, one with an extended bill and a back flap to cover the ears and neck is particularly effective. Following are additional suggestions for sun safety.

- If you must be out in the sun, cover up with a wide-brimmed hat, preferably made with tightly woven fabric. Also, wear long sleeves and light-colored pants.

- Use sunscreen products. Sunscreens are rated with a number called a sun protection factor (SPF). The higher the number, the greater the protection. Use SPF 15 or greater. SPF 30 sunscreens are only about 3 or 4 percent more effective.

- Apply sunscreens properly. Some sunscreens need time to bind with the skin oils and should be applied 30 minutes before exposure to the sun. Cover all exposed areas, including palms, ears, and nose. Reapply to the body and face about every three hours, and reapply after swimming. Don't forget to use it in the shade and on cloudy days. Some UV rays still get through.

- Use lip balm that contains sunscreen. The lower lip is one of the most common sites for skin cancer.

- Be alert to reflected UV light from sand, water, cement, or snow.

- Wear sunglasses that filter out ultraviolet radiation. Those that are labeled to block out over 70% of UVB rays are good choices.

- When travelling, remember that radiation increases at higher altitudes. Radiation also increases the closer you get to the equator.

- Stay out of the sun when taking certain medications (such as antibiotics and diuretics) that make the skin more light-sensitive. Check with your doctor.

Finally, try to stay out of the sun between 10 a.m. and 3:00 p.m. Keep infants and young children out of the sun as much as possible. Eighty percent of the sun's damage occurs within the first eighteen years of life. For more information, contact your health care provider.
