Implement all key precautions. Warding off sun damage is critical. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Regularly apply and reapply a broad-spectrum sunscreen with a minimum SPF 30 every two hours, or straight after swimming or an outdoor activity. Heed this! UV intensity is much stronger when reflected off sand and water.
