Undertake all critical precautions. Protection from sun harm is vital. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. After a swim or outdoor exercise, one should liberally reapply broad-spectrum sunscreen with a sun protection factor of 30 or higher. Take heed! Reflections of sand and water make the Sun's UV rays stronger.
