Why is it dangerous?

The sun gives off rays of light that can help and harm us. These are known as ultraviolet (UV) rays. There are three different types of UV rays: UVA, UVB, and UVC.

UVA

  • UVA rays penetrate windows and clouds
  • UVA makes up 95% of the UV radiation reaching Earth
  • UVA is the main type of light that is used in tanning beds, and is also the cause of tanning in the sun.
  • UVA isn't as intense as UVB but penetrates your skin deeper.
  • Causes premature aging and skin cancer.

UVB

UVB

  • UVB penetrates and damages the outermost layers of your skin
  • UVB can damage your skin year-round
  • UVB rays can be filtered and do not penetrate glass.
  • Can cause sunburn and even blistering.

UVC

  • The Worst
  • Germicidal/disinfectant
  • May produce chemical bond breakage and ionization of some atoms and molecules.
  • The Ozone layer fortunately protects us from these rays.
