Ultraviolet B (UVB) radiation

Ultraviolet B (UVB) radiation is a type of sunlight that has a shorter wavelength than UVA radiation. It is primarily responsible for causing sunburn and can lead to skin cancer with prolonged exposure. UVB rays are more intense in the summer and at higher altitudes, and they do not penetrate glass, meaning they affect you outdoors but not indoors. Sunscreens often contain ingredients specifically designed to block UVB rays, making them crucial for skin protection during sun exposure. Moderation and protective measures are important to reduce the risk of skin damage from UVB radiation.
