Employ every crucial safety step. Those with fair skin could experience burns in a matter of minutes. 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. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Broad-spectrum SPF 30+ sunscreen must be generously applied and reapplied every two hours or post any outdoor activity or swim. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
