Ultraviolet (UV) radiation is a type of electromagnetic radiation that has a shorter wavelength than visible light. It’s produced by the sun and can also be emitted by artificial sources like tanning beds. Even though UV isn’t visible, it can have both beneficial and harmful effects on living beings and the environment.

UV from the sun is important for our bodies to produce Vitamin D, which helps us absorb calcium and maintain strong bones. However, overexposure to UV radiation can cause sunburn, premature aging of the skin, and increase the risk of skin cancer. This is why it’s important to protect our skin by wearing sunscreen, hats, and protective clothing when we’re outside.

UV also has significant effects on the environment, causing damage to plant life, marine ecosystems, and contributing to the depletion of the ozone layer. The ozone layer acts as a protective layer that blocks harmful UV radiation from reaching Earth’s surface. However, human activities like the production of chlorofluorocarbons (CFCs) have significantly depleted the ozone layer, leading to increased levels of UV radiation on Earth.
