Sun & Skin Safety Tips Sunscreen Is Not Just for Sunny Days SPF 30+ sunscreen should be worn every day, even if the sun is not shining. Clouds only block 20 to 30 percent of UV rays. What Does SPF Mean? Sun Protection Factor is an estimate of how well the sunscreen will protect your skin from burning. The higher the number the better. Protective Clothing Use proper clothing, umbrellas and shade trees to keep out of direct sunlight. Add protection by wearing a long-sleeved shirt, pants, a wide-brimmed hat and sunglasses. If You Love Outdoor Activities Use a water-resistant broad-spectrum UVA/UVB sunscreen with SPF of 30+. Reapply every two hours or immediately after being in water. The 10-2 Rule Even when you follow precautions, it is best to limit time in the sun during the hours of 10 am and 2 pm.
