Both tanning bed burns and sunburns can be extremely painful. Sunburns tend to be more common because people are often overexposed to UV radiation when they’re outdoors. Tanning bed burns are less common, but they can be just as painful; that’s because tanning salon operators are careful to have customers adhere to regulations, e.g. not tanning more than once per day. If you do get a burn from a tanning bed, it’s important to seek medical attention right away.
