Moderate amounts of sunlight are good for us, but excessive exposure can have serious consequences. Sunburn should be taken seriously as a warning sign. Although sunscreens can reduce exposure to the ultraviolet (UV) radiation that is linked to cancer, aaplying some lotion is not enough for preventing skin cancer. Some studies suggest that sunscreen use can be harmful if people spend more time in the sun because they feel protected. In addition to sunscreen, other ways to minimize UV exposure include wearing wide-brimmed hats, long sleeve shirts and long pants, and sunglasses that block UV rays.
