Sunscreen keeps out the harmful rays of the sun. Even when swimming or being in water people should use sunscreen. The sun's rays can reach through to about 3 feet of water. Sunlamps, tanning parlors or tanning pills are just as harmful to skin and even more so when exposed to the sun. For any concerns about heat illnesses call a doctor or local hospital.
