To prevent the layer and to protect the harm causing by it
Answers
People who get a lot of exposure to ultraviolet (UV) rays are at greater risk for skin cancer.
Sunlight is the main source of UV rays, but you don’t have to avoid the sun completely. And it would be unwise to stay inside if it would keep you from being active, because physical activity is important for good health. But getting too much sun can be harmful. There are some steps you can take to limit your exposure to UV rays.
Some people think about sun protection only when they spend a day at the lake, beach, or pool. But sun exposure adds up day after day, and it happens every time you are in the sun.
Simply staying in the shade is one of the best ways to limit your UV exposure. If you are going to be in the sun, “Slip! Slop! Slap!® and Wrap” is a catchphrase that can help you remember some of the key steps you can take to protect yourself from UV rays:
Slip on a shirt.
Slop on sunscreen.
Slap on a hat.
Wrap on sunglasses to protect the eyes and skin around them.
