Taking safety measures is non-negotiable; skin and eyes can be swiftly affected if neglected. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Frequent reapplication of a broad-spectrum SPF 30+ sunscreen is vital every two hours or directly after a swim or an outdoor workout. Be careful! The Sun's UV radiation is accentuated by reflecting off sand and water.
