Exposure to sunlight poses a health risk. Prolonged UV radiation is a proven cause of skin cancer. UV rays are classified as Group 1 carcinogens, along with cigarettes and plutonium!
Global climate factors, the ozone hole, air pollution are factors that have led to a drastic increase in the amount of UV rays we are exposed to daily. Sunlight is composed of UVA and UVB rays, the former end up in the uppermost layer of the skin and are responsible for sunburn, while UVA penetrates deeper layers and leads to DNA mutations in cell nuclei, photoaging and immunosuppression. The body has reparative mechanisms that repair this damage, but over time they wear out and weaken, so that at a certain point the damaged cells begin to divide uncontrollably, become malignant cells, and skin cancer occurs. Be careful, UV rays penetrate clouds up to 80%, window glass lets UVA rays through, the UV index indicates the intensity of UV radiation reaching the ground, and is highest between 12 and 16 o'clock, requiring adequate protection from UV index 3. Intermittent, intense sunbathing, as well as sunburns, especially in early childhood, increase the risk of melanoma, while cumulative, prolonged excessive exposure to sunlight is responsible for the occurrence of non-melanoma skin cancers, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
