UVAUVBexponering

UVAUVBexponering refers to the exposure of skin to ultraviolet (UV) radiation from the sun, which is composed of UVA and UVB rays. UVA rays penetrate deeper into the skin and are primarily responsible for premature aging, such as wrinkles and sunspots. UVB rays are shorter and primarily affect the epidermis, the outer layer of the skin, and are the main cause of sunburn.

Both UVA and UVB radiation can damage DNA in skin cells, which can lead to skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma. The cumulative effect of UV exposure over a lifetime increases the risk of developing these cancers. The intensity of UV radiation varies depending on factors such as time of day, season, latitude, and altitude.

Protection against UVAUVBexponering is crucial for skin health. This can be achieved through measures such as wearing sunscreen with a high Sun Protection Factor (SPF) that offers broad-spectrum protection against both UVA and UVB rays, wearing protective clothing, seeking shade, and avoiding prolonged sun exposure during peak UV hours. Regular skin checks by a dermatologist can help detect any potential skin changes early.
