Limit sun exposure. Avoid direct sunlight during the hours of 10 a.m. to 4 p.m. when the solar radiation is strongest. Cloudy days don’t offer much protection – many of the sun’s rays can pass through clouds, especially ultraviolet. Being around water can intensify sunlight through reflection and the fact that water’s ability to cool the skin can make people unaware they are getting burned.
Use a good UVA/UVB sunblock with a SPF (sun protection factor) of 30 or higher. Look for “broad spectrum” sun screen – the best kind contain titanium dioxide. Also, use waterproof sunblock so it stays on your skin if you perspire of get wet.
Protective clothing such as a wide-brimmed hat will help shield your face, ears, and neck. Be sure your sunglasses filter out ultraviolet radiation.
Avoid sun tanning, which includes artificial sunlight at tanning salons.
