Beach safety is essential for enjoying a day by the ocean. Always swim in designated areas where lifeguards are present, as they can respond quickly in emergencies. Be aware of rip currents, which can pull swimmers away from shore. If caught in one, swim parallel to the beach until free, then head back to shore. Sun protection is also crucial. Apply a broad-spectrum sunscreen with at least SPF 30, and reapply every two hours, especially after swimming. Wearing a hat and sunglasses can help shield your skin and eyes from harmful UV rays. Stay hydrated and take breaks in the shade to avoid heat-related illnesses.
