Always take precautions; unprotected eyes and skin can be damaged rapidly. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Apply generously and frequently reapply a sunscreen with SPF 30 or more even on cloudy days, particularly after a swim or outdoor exercise. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
