Take important precautions because unprotected skin can burn and be harmed swiftly. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days. Consistently applying sunscreen with a minimum of 30 SPF is a sure way to protect against sunburn and harmful radiation. Attention! UV strength is notably upped by the reflection of sand and water.
