Take all required precautions, as unprotected skin and eyes can burn in minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. Prompt application of a broad-spectrum sunscreen, SPF 30+, is necessary after a swim or an outdoor workout and it should be re-applied every two hours. Attention! UV strength is notably upped by the reflection of sand and water.
