Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. A broad-spectrum sunscreen of SPF 30+ should be used liberally and reapplied every two hours or post an outdoor workout or swim. Take note! The UV strength of the Sun elevates when reflected off water and sand.
