Experience reduced UV exposure by about half when donning a wide-brim hat. Even when it's cloudy, ensure the generous application and frequent reapplication of a sunscreen with at least 30 SPF, particularly post swim or outdoor activity. Warning! The reflection of sand and water increases the UV dose.
