Remember to safeguard yourself. Rapid damage can occur to skin and eyes 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. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. When outdoors, it's wise to limit direct sunlight exposure, especially if you have sensitive skin. Always use sunscreen with a minimum 30 SPF. Attention! The combination of sand and water reflections enhances UV ray intensity.
