Are you sun safe every day? Take the American Cancer’s Society’s 9-question quiz to find out.According to the American Cancer Society, skin cancer is one of the most preventable forms of cancer. More than 3.5 million cases are diagnosed each year. An obvious, but very important way to limit your exposure to UV light is to avoid being outdoors in direct sunlight for too long. This is particularly important between the hours of 10 a.m. and 4 p.m., when UV light is strongest. If you are unsure how strong the sun’s rays are, use the shadow test: if your shadow is shorter than you are, the sun’s rays are the strongest, and it’s important to protect yourself.
