Long-term exposure to ultraviolet (UVA and UVB) radiation damages your skin’s top layer. It increases your chance of developing skin cancer — the most common form of cancer in the United States. The sun produces UVA and UVB rays, but so do tanning beds and sunlamps. They have been linked to malignant melanoma, the deadliest form of skin cancer. And they should be avoided.
Lather the lotion.
Sport the shades.
Wear a wide brim.
Cover up with clothes.
Seek less sun.
Use a water-resistant sunscreen with UVA and UVB protection, and broad-spectrum SPF of 30 or higher. Apply it liberally and reapply every two to three hours, or more frequently if you're swimming or perspiring.
Make sure you cover up. Protect your eyes with sunglasses that block 99 percent or more of UVA and UVB light. Wear wide-brimmed hats to cover your head, face, neck, and ears. And wear long-sleeve shirts and pants.
Limit sun exposure when UVA and UVB rays are most dangerous — from 10 a.m. to 4 p.m. Don’t let children get sunburned. Encourage them to play in shaded areas or stay indoors.
