While I'm sure most people tan because they like the look that it creates, tanning can actually be beneficial to those that suffer from depression or SAD (seasonal Affective Disorder).
Many therapists/dcotors may suggest tanning occasionaly, or even a special lamp that creates artificial sunlight, to improve mood, and help battle depression because that dose of light can do wonders.
While tanning often will damage the skin, using a tanning bed once in a while to help battle SAD is a good thing.
