Adopt all essential precautions. Preventing sun harm is crucial. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key. After a swim or an outdoor workout, generously apply and regularly reapply a sunscreen with at least SPF 30, even if the day is cloudy. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
