Without proper safety measures, skin and eyes can be quickly harmed. Be sure to protect yourself. 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. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. Before exposing yourself to the Sun, apply sunscreen with 30 SPF or higher. This safeguards against sunburn and its harmful radiation. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
