Other hazards at the seacoast include stinging jellyfish and coral, but the biggest threat to beach goers is sunburn. Baking in the sun can cause considerable skin damage and eventually lead to skin cancer. Children are most at risk. Even one bad sunburn can later lead to the serious skin cancer called melanoma, which can be fatal. Fair-skinned people are especially at risk.
Sunburn is a particular problem at beaches because of the strong reflection off the beach and water.
Remember to put suntan lotion on your feet, which burn easily. The sun is much more intense in lower latitudes like Florida and Hawaii, and special care should be taken during the summer months. Quality sunglasses should be used to protect your eyes against cataract-causing UV rays. UV protection should not be confused with the darkness or tint of the glasses. Some people also like to use anti-glare Polaroid lenses.
