This blog explains that UV radiation is a type of electromagnetic radiation like infrared and visible light. UVA, UVB and UVC are distinct in terms of where they sit on the electromagnetic spectrum but also their potential impact on humans. UVA and UVB are both responsible for skin cancer and melanoma.
Many of us see the ultraviolet (UV) index on weather reports and read about UV alerts at particular times of the day. But do you know what it actually means and how it affects you?
There are two main types of UV rays and both cause damage to skin cells and contribute to skin cancer. Ultraviolet light is a form of radiation invisible to the human eye. Ultraviolet wavelengths of sunlight are made up of UVB, which has shorter wavelengths and higher energy, and UVA, which has longer wavelengths and lower energy.
You can see sunlight and feel the sun's heat. However, you cannot see or feel ultraviolet (UV) radiation.
It’s a common misconception that sun damage only occurs in hot climates, as many people associate damage with the visible signs of sun exposure, i.e sunburn.
You may be surprised to learn that the sun’s UVA and UVB rays actually have different, yet equally harmful, effects on the skin. They also have the potential to cause damage in the winter, as well as in the summer.
