Adopt every precaution of necessity, unprotected skin and eyes may suffer burns instantly. 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. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Applying and reapplying a broad-spectrum sunscreen with a minimum SPF 30 after every two hours, outdoor workout, or swim is recommended. Heed this! UV intensity is much stronger when reflected off sand and water.
