Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Every two hours, apply and reapply an SPF 30+ broad-spectrum sunscreen, especially after swimming or engaging in outdoor activities. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
