You need to protect your skin from the sun every day, even when it's cloudy. That's because the sun's damaging ultraviolet A (UVA) and ultraviolet B (UVB) rays go right through clouds. Too much sun can make your skin wrinkly and might even give you skin cancer. To protect yourself: 

• Use sunscreen with a sun protection factor (SPF) of at least 30. Look for a sunscreen that protects you from both UVA and UVB rays. When a sunscreen protects against both, the bottle might say the sunscreen offers “broad-spectrum” sun protection.
• Cover up by wearing a hat, sunglasses, and clothes that cover your arms and legs, if possible.
• Seek shade when the sun's rays are strongest, between 10 a.m. and 2 p.m.
