Slip, slop and slap are the three S's that every sun-lovin' camper should know them. First, slip on a shirt (long-sleeved if possible) to protect vulnerable areas like your shoulders and back. Then get sloppy and slop on lots of sunscreen with an SPF (sun protection factor) of 15 or higher. Finally, slap on a wide-brimmed hat and you'll keep 70% of the sun's rays off your face and neck.
Even on cloudy days, water and sand can reflect more than half of the sun's rays on your skin. This adds up to extra exposure to your head, shoulders, and other parts of your body that are above the water's surface. The sun's burning ultraviolet (UV) rays can also pass through clouds and water, so you can get burned on a cloudy day or while swimming. This is bad news because years of getting sunburned can add up to dry, wrinkled skin or, even worse, skin cancer.
Also, try to stay out of the sun from 10 am to 3 pm when the sun is strongest. Why are these bright ideas? Because you'll really see them pay off with smooth and healthy-looking skin when you're older! Most people get 80% of their lifetime exposure to the sun by the time they're 18. So now's the time to get a headstart on being sunsmart.
