What Is Ultra-Violet Radiation?

Ultra-violet radiation, also known as UV, is a form of radiation put out naturally by the sun, and through tanning beds and certain lamps. This radiation is also known to be the primary cause of skin cancers in individuals.

Ultra-violet radiation comes in 3 different wavelength rangers: UVA, UVB, and UVC. UVA rays are linked to skin aging and damage such as wrinkles. UVB rays are known for causing sunburns. UVC rays are ultra-violet rays that come from the sun but do not make it through the Earth's atmosphere, so they are not known to cause skin cancer. However, UVA and UVB are known to play a role in the development of skin cancers (especially UVB) and can cause aging skin and wrinkles (primarily UVA).

One can experience skin damage, skin deformities, skin changes, and skin cancer from getting too much UV radiation. Most UV rays will cause aging and damage to the DNA cells of your skin, which is why the deformation of moles, birthmarks, and other skin marks may be the place to look for cancerous cells.

You can reduce your risk of getting skin cancer from ultra-violet radiation by wearing sunscreen, avoiding UV radiation during the time of the day where the strength of the rays is strongest (typically between 11am and 3pm), and by wearing long-sleeved shirts that are light-weight to stay cool and protect your skin from damage. Another way to know the strength and severity of UV rays during the day is by checking in with the National Weather Service to view the UV Index, which is available online, in the newspaper, and on television as a number between one to eleven. The higher the number, the more UV rays are reaching the Earth's surface around midday.

Knowing how to protect your skin is the first step to preventing skin cancer, and can help you keep your skin healthy, young and vibrant.
