　　What are these basics?

　　2

　　So it is best to concentrate most outdoor activities before and after these hours. Next, teach them about shade. Encourage children to seek shade whenever possible under a leafed tree, a sun umbrella, or a building — any shaded area can offer some protection.

　　3

　　Clothing is, in fact, considered the best single form of sun protection by many experts. The more skin covered, the better. So look for lightweight, long-sleeved shirts and long pants.

　　Also encourage children to wear a broad-brimmed (宽边的) hat. Even a baseball hat is better than no hat! UV rays can lead to eye diseases in adulthood.

　　4

　　The best sunglasses keep away 99-100 percent of both UVA and UVB rays — the tag should state this. Close-fitting, wrap-around sunglasses provide the most protection.

　　5

　　I recommend a water-resistant sunscreen (防晒霜) (SPF 50) protection. Children should apply some sunscreen to the face and body a full 30 minutes before going outside, and reapply every two hours or immediately after swimming or sweating heavily. Supply children with a container of sun-screen to take with them on all outings.

　　A. A physical block, like sun-protective clothing, is also a must.

　　B. First of all, the sun is strongest from 10 AM to 4 PM.
