Without constant care, eyes and skin might suffer damage in a short time. 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. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. Even when the sky is cloudy, apply generously and frequently reapply a sunscreen with SPF 30 or more, especially post every swim or outdoor exercise. Stay vigilant! UV rays get a boost in intensity due to sand and water reflections.
