UVkaitse

UV kaitse refers to the measures, products, and practices that limit exposure to ultraviolet (UV) radiation from the sun and artificial sources. The aim is to prevent acute effects such as sunburn and long-term risks including skin cancer and photoaging. It includes behavior, protective clothing, and topical products.

Ultraviolet radiation is classified into UVA, UVB and UVC. UVC is largely filtered out by the atmosphere and does not reach the Earth's surface. UVA penetrates deeply and contributes to skin aging and some cancers, while UVB is the primary cause of sunburn and a major factor in skin cancer. UV exposure depends on time of day, season, latitude, altitude, and reflective surfaces like water, sand, and snow.

Protective measures include using broad-spectrum sunscreen that shields against UVA and UVB, commonly labeled with an SPF value. SPF indicates protection against UVB, while broad-spectrum labels indicate UVA protection. Sunscreen should be applied to all exposed skin, re-applied every two hours or after swimming or sweating, and used in combination with shade and protective clothing. The term UPF describes the UV-blocking performance of fabrics.

Protective clothing and accessories play a key role: wide-brimmed hats, long sleeves, and garments with UPF ratings reduce exposure. Sunglasses should provide 100% UV protection (UV400). Lip balms with SPF offer protection for the lips.

Practical guidance includes checking the daily UV index, seeking shade during peak sun hours, and applying extra protection for children and individuals with light skin. UV kaitse is relevant year-round, as reflections from snow, water, and sand can increase UV exposure.
