We are into summer weather and sunburn is a real risk. Sunburn dramatically increases the risk of skin cancer, and the UV rays can cause premature aging of the skin.
Prevention is the best approach. Wear sunscreen on both sunny and cloudy days. UV rays get through the clouds. Put on sunscreen 15-30 minutes before going outside. Reapply it every 2 hours and after getting out of the water.
It is best to use a broad-spectrum sunscreen with sun protective factor (SPF) 30 or higher. It takes about 1 ounce to cover an average adult’s body.
It is helpful to wear clothes with a UV protective factor listed on the label. Wear a wide brimmed hat. Avoid midday sun exposure.
Children less than 6 months old should be kept out of direct sunlight. People with light skin, blue eyes, and blond or red hair are at the highest risk of sunburn, but all skin colors are at risk.
Also, remember that sun rays can bounce off of sand, water, and concrete. Sunglasses should be worn, even by kids. Stay safe!
