Practice all-important precautions. Light skin people may get burned in less than 5 minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. 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. Prolonged stay under the direct sun should be avoided as much as possible, especially if a person burns easily. Sunscreen with a minimum 30 sun protection factor should always be used. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
