Protecting your skin from ultraviolet (UV) radiation is one of the most effective ways to reduce the risk of skin cancer, premature aging, and sunburn.
Key recommendations
- Seek shade, especially between 10 a.m. and 4 p.m.
- Wear sun-protective clothing, a wide-brimmed hat, and UV-blocking sunglasses
- Use a broad-spectrum sunscreen with SPF 30 or higher
- Apply enough sunscreen (about a shot-glass amount for the whole body) and reapply every two hours, or after swimming or sweating
- Avoid indoor tanning completely
Choosing sunscreen
Look for “broad-spectrum” (protects against UVA and UVB), SPF 30 or higher, and water resistance if you will swim or sweat. Mineral (zinc oxide, titanium dioxide) and chemical filters can both be effective when used correctly.
Sunscreen is only one part of sun protection. Clothing and shade provide more reliable coverage.
