The sun’s rays are the strongest from mid-morning to late afternoon. Try to stay out of the sun during these hours. If you're outside, stay in the shade — like under a tree or umbrella.
Wear a long-sleeved shirt and long pants or a long skirt when you spend time outdoors. Clothes made from tightly woven fabrics are best for blocking UV rays.
Wear a hat with a wide brim that protects your face and neck. Avoid straw hats with holes that let sunlight through. If you wear a baseball cap or visor, be sure to protect your ears and the back of your neck with sunscreen.
It’s also important to wear sunglasses that block UV light. This will help protect your eyes and the skin around them from sun damage. Wrap-around sunglasses are best because they block UV rays from the side and the front.
Use sunscreen with both UVA and UVB protection, also called broad spectrum sunscreen. Check the expiration date on the bottle to make sure it’s not out of date.
To get the most protection:
