Employ every crucial safety step. Those with fair skin could experience burns in a matter of minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Experience reduced UV exposure by about half when donning a wide-brim hat. Sunscreen with a sun protection factor of no less than 30 should be used liberally and reapplied frequently on overcast days, including after every swim or outdoor activity. Caution! The mirror effect of sand and water ups the UV radiation strength.
