Always be cautious. Skin and eyes can be affected swiftly without protection. 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. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Broad-spectrum sunscreen with an SPF of 30 or more should be applied liberally every two hours and directly after outdoor activities or swimming. Heed this! UV intensity is much stronger when reflected off sand and water.
