Sunburn (also called erythema) is caused by overexposure to ultraviolet radiation (UV rays).

Health effects of ultraviolet radiation

Ultraviolet (UV) radiation has some benefits. But as with all forms of radiation, there are risks involved with overexposure to UV radiation (rays).

Skin cancer

Skin cancer is the most common of all cancer types. About one third of all new cases of cancer in Canada are skin cancers, and the rate continues to rise. Skin plays a vital role in keeping you healthy.
