Protect yourself from sun overexposure! In summer, always apply sun block SPF 15 or more to protect your skin from solar UV radiation. Just five or more sunburns can really increase your risk of developing skin cancer. The sun's rays are strongest between 10 a.m. and 4 p.m. so at the times, seek shade or wear protective clothing such as a long-sleeved shirt.
In lieu of summer, check out this website from the EPA. The website also gives informative information explaining UV alerts. Sign up to get free UV alerts here!
