For Fourth of July weekend many of us will be heading outside for picnics, barbecues, or hitting the trails for a hike. Make sure to take along sunscreen, sunglasses and a hat to help protect your skin from the sun. According to the Colorado Department of Public Health, 90% of skin cancers are caused by overexposure to UV radiation. Check out the Sun Safe Colorado prevention strategies website for tips on preventing skin cancer. Statistics and other skin cancer information are available from the Colorado Department of Public Health and Environment.
