Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Apply liberally and reapply a broad-spectrum sunscreen of SPF 30+ every two hours, and promptly after any outdoor workout or a swim. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
