Always prioritize safety measures. Rapid harm can befall unprotected skin and eyes. 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. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Prolonged stay under the direct sun should be avoided as much as possible, especially if a person burns easily. Sunscreen with a minimum 30 sun protection factor should always be used. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
