From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun. Apply generously and frequently a broad-spectrum SPF 30+ sunscreen every two hours, or immediately after swimming or any outdoor exercise. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
