Undertake all key precautions, as unprotected skin and eyes may get burns in no time. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Even if it's cloudy, generously apply and frequently reapply a sunscreen with no less than a 30 sun protection factor after each swim or outdoor exercise. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
