UVB (Ultraviolet B)

UVB (Ultraviolet B) is a type of ultraviolet radiation from the sun that reaches the Earth's surface. It plays a key role in producing vitamin D in our skin, which is essential for healthy bones and immune function. However, overexposure to UVB can cause skin sunburns and increase the risk of skin cancer. Its intensity varies with the time of day, season, and geographic location. Protecting your skin from excessive UVB exposure through sunscreen, clothing, and seeking shade helps prevent damage while still allowing some benefit from sunlight.
