If you’re going to be in the sun, be sure to generously apply a broad-spectrum, water resistant sunscreen with an SPF of 15 or higher. Sunscreen should be applied to all exposed skin, even during winter or cloudy days. For prolonged outdoor activity, use a sunscreen with an SPF of 30 or higher. It should be reapplied roughly every two hours and right after swimming or sweating.
Other sun-safe habits:Wear protective clothing such as a long-sleeved shirt, pants, a wide-brimmed hat, and UV-protection sunglasses, where possible.
Seek shade when available, especially between 10 a.m. and 4 p.m., when the sun’s rays are strongest.
Use extra caution near water, sand, and snow, because they reflect and intensify the rays of the sun, which can increase your chances of sunburn and skin damage.
Avoid tanning booths and beds. Ultraviolet light from the sun and indoor tanning can cause skin cancer and wrinkling.
Perform regular self-skin examinations. If you notice anything changing, growing, or bleeding on your skin, see a dermatologist.
