The sun, tanning beds, and sun lamps expose us to ultraviolet (UV) radiation. This radiation is so dangerous that the United States Department of Health and Human Services has declared UV radiation from the sun and artificial light sources, such as tanning beds and sun lamps, as a known carcinogen (tends to cause cancer). We know that UV radiation can cause skin cancer, the most common cancer in the world. It can damage our immune system. And, it can prematurely age our skin, giving us a wrinkled and leathery look.
Some people seek the sun to get their daily dose of vitamin D. While we need vitamin D for healthy bones, the American Academy of Dermatology does not recommend getting vitamin D from the sun or tanning beds. Doing so increase our risk of getting skin cancer. Healthier ways to get this important nutrient are to eat foods rich in vitamin D and take a supplement.
Indoor tanning beds or lamps are not a safe option to sun exposure. Like the sun, tanning beds and sun lamps expose us to two types of UV radiation. The UVA rays penetrate more deeply into our skin and speed up the aging of our skin. The UVB rays do not go as deep, but they do cause burns. Yes, burns can and do happen in some people who use indoor tanning. Some burns require a trip to the emergency room.
Some tanning lamps emit UV radiation many times stronger than that of the sun. Studies show that indoor tanning raises the risk of melanoma by 75% and increases the chance of getting other types of skin cancer.
When melanoma, a type of skin cancer, is found early and treated, the patient can be cured. But, melanoma can be fatal. In the United States, the number of melanoma causes a rising. Other types of skin cancer may not be fatal, but can invade and destroy surrounding tissue, causing disfigurement and sometimes painful reconstructive surgery.
It can take many years to see the effects of UV radiation on our skin. Skin cancer and signs of premature skin aging tends to show up years after we begin tanning. As such, young people are often unaware of the dangers of tanning. The number of cases of skin cancer likely will keep rising as people who are tanning in their teens and 20s reach middle age.
Signs of premature aging of the skin, such as wrinkles and age spots, eventually appear in everyone who repeatedly tans. These signs may be less apparent and take longer to show up in some people. This does not minimize the risk. People who tan greatly raise their risk of getting skin cancer.
