Ultraviolet (UV) radiation damages DNA, accelerates skin aging and raises the risk of skin cancers, especially melanoma. Research highlighted that as few as five severe sunburns can double the likelihood of developing melanoma.
Drivers are exposed to uneven UV levels, receiving up to five times more radiation on the left side of the face and arm when seated behind a closed car window. Frequent mistakes in sunscreen use include failing to reapply every two hours or after swimming or sweating, and applying too little—experts advise a shot‑glass amount for the body and at least half a teaspoon for the face and ears. The scalp is identified as a “dead zone” where skin cancer often appears, prompting recommendations to wear wide hats or apply sunscreen directly to the scalp.
Proper protection combines regular sunscreen reapplication, sufficient quantity, and additional measures such as protective clothing, hats, and awareness of hidden exposure areas.
