Ever since tanning beds were invented, there have been conspiracy theories on which is worse for you… using tanning beds or tanning with the sun.
Medical experts have been revealing that tanning beds are not a safe alternative to the sun, but rather, people are just damaging their skin .
The main difference between tanning beds and the sun is the intensity and type of radiation. Natural sunlight has a balance of UVA and UVB rays. If you tan outside for too long, your body reacts to the rays by burning the skin. In the long run, tanning beds are made to give a massive amount of UVA radiation, around 10 to 15 times higher than what someone would gain from tanning outside. The tanning bed is not reliable to get vitamin D, due to it being UVA rays.
UVA rays have longer wavelengths, meaning they don’t just sit on the surface; they actually penetrate deep into the skin. This is where the real damage happens. These rays chew through the fibers that keep your skin bouncy and young, leading to that “glowy” look and premature aging way earlier than nature intended. Even scarier, these harsh rays cause immediate genetic mutations in your skin cells. People often think that you need years of tanning to do damage, but research actually shows that even a single tanning bed session can jump-start the risk of melanoma by a staggering 20%.
It isn’t just about the long-term cancer risk. Those high-pressure UVA lamps are the primary culprits behind permanent “age spots,” which are dark pigment changes that don’t go away. Also, deep wrinkling is caused by the total change of the skin’s support system. You’re essentially trading a temporary tan for permanent damage to your skin.
At the end of the day, while being outside still requires a lot of management and a good bottle of SPF, tanning beds are a different kind of intense use. They aren’t a shortcut to a healthy look; they’re just a high-speed lane to skin damage.
“There’s no such thing as a safe tan when it comes from a UV bed,” said UnityPoint Health.
