Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck. Every two hours, apply and reapply an SPF 30+ broad-spectrum sunscreen, especially after swimming or engaging in outdoor activities. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
