The best way to protect yourself from the sun’s harmful ultraviolet rays is to wear long sleeves and long pants. But if you have a job in which you must wear less clothing, such as a lifeguard, be sure to completely cover yourself with sunscreen. Experts suggest applying sunscreen about 20 minutes before you’re in the sun and allow it to dry, then reapplying at least every two hours.
When picking sunscreen, a sun protection factor (SPF) of at least 15 is good, but 30 is better. SPF 30 is protective against 97 percent of the sun’s rays, whereas SPF 15 is protective against only 93 percent. When applying sunscreen, pay special attention to the tip of your nose, the tips of your ears and your neck.
