Summer sun: Know the danger zone

By Mayo Clinic Staff

Be smart when it comes to sun protection. The sun's rays are most damaging between 10 a.m. and 4 p.m. Schedule outdoor activities for other times of the day, even in winter or when the sky is cloudy. If you must be outdoors during these peak hours, seek shade whenever possible.
