Ultraviolet-B (UVB)
Ultraviolet-B (UVB) is a type of ultraviolet radiation from sunlight that reaches the Earth's surface. It plays a key role in producing vitamin D in our skin, which is essential for bone and immune health. However, excessive UVB exposure can damage skin cells, leading to sunburn, skin aging, and increasing the risk of skin cancer. UVB rays are most intense during midday, and their intensity varies with factors like geographic location, altitude, and weather conditions. Protecting your skin with sunscreen, clothing, or shade during peak sunlight hours reduces potential harm from UVB radiation.
