Americans love the sun and spend a great deal of time outside—working, playing, exercising—often in clothing that exposes a lot of skin to the sun. Most people are now aware that too much sun has been linked to skin cancer. However, few know the degree of risk posed by overexposure, and fewer are aware that the risks go beyond skin cancer. Recent medical research has shown that overexposure to the sun’s UV radiation can contribute to serious health problems. Each year, for example, more than 1 million cases of skin cancer are diagnosed in the United States, and one person dies every hour from melanoma or nonmelanoma skin cancer. This section provides a quick overview of the major problems linked to excess UV exposure: skin cancer (i.e., melanoma, basal cell carcinoma, and squamous cell carcinoma); other skin problems; cataracts and other eye damage; and immune system suppression. Understanding these risks and taking a few sensible precautions described in this booklet will help you to enjoy the sun while lowering your chances of sun-related health problems later in life. read more
