UVAUVBsäteilyä

UVAUVBsäteilyä, often referred to as UVA and UVB radiation, encompasses specific portions of the ultraviolet light spectrum that reach Earth's surface. UVA radiation has a longer wavelength and penetrates deeper into the skin. It is primarily responsible for premature aging, including wrinkles and sunspots. UVB radiation has a shorter wavelength and affects the outermost layer of the skin. It is the main cause of sunburn and plays a significant role in the development of skin cancer.

Both UVA and UVB radiation are emitted by the sun and can also be found in artificial sources like tanning beds. Exposure to these types of radiation can have detrimental effects on human health. While the body produces vitamin D when exposed to UVB radiation, this benefit is outweighed by the increased risk of skin damage and cancer with excessive or unprotected exposure.

Protective measures against UVAUVBsäteilyä include using broad-spectrum sunscreen, wearing protective clothing, and seeking shade during peak sun hours. Understanding the differences and impacts of UVA and UVB radiation is crucial for effective sun protection and maintaining skin health.
