Being unprotected puts skin and eyes at risk of rapid damage. Always be safe. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Caution! The mirror effect of sand and water ups the UV radiation strength.
