People must realize that the ocean is not a swimming pool. Waves make an oceanic beach exciting, but big waves can be dangerous and also generate strong currents. Tides can also produce strong currents at constricted areas, particularly inlets between islands. 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.
