Tanning beds refer to devices that emit ultraviolet (UV) radiation, typically in the form of artificial sunlight, for the purpose of inducing tanning or increasing skin color. These machines are commonly used by people who want to achieve a tan without having to spend time outdoors in the sun. Tanning beds can be found at gyms, salons and other places that offer tanning services. The use of these devices has become popular over the years as an alternative way to get a tan, but there are concerns about the safety of using them due to potential health risks such as skin cancer and premature aging of the skin.
