“Sometimes people think you can only have a high UV index when it’s very hot, but actually UV index and temperature are distinct concepts. The UV Index gives a daily forecast of the expected risk of overexposure to the sun’s rays. There are three primary types of UV radiation: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). You can monitor the UV Index where you are using the Environmental Protection Agency’s (EPA) website or their app. The UV index is another tool to help us plan around the UV exposures of the day,” says Gupta.
