UV-B

UV-B is a type of ultraviolet light from the sun that reaches the Earth's surface. It has a medium wavelength and is responsible for causing sunburns and tanning. While some UV-B exposure helps the body produce vitamin D, too much can damage skin cells, lead to premature aging, and increase skin cancer risk. Protective measures like sunscreen, clothing, and seeking shade are recommended to limit unnecessary UV-B exposure while still benefiting from safe sun exposure for vitamin D synthesis.
