Why Tanning Makes Me Feel Good
Sunbeds And Uv Exposure: Can They Elevate Mood? By John Cannell, M.D. (Vitamin D Council)
I ran across a 2002 paper that begins, “People tend to feel better after exposure to ultraviolet (UV) radiation.” The authors are seven German scientists from Ruhr-University.
The team of researchers measured different aspects of psychological well being
in 53 volunteers before and after sunbed use. At baseline, all volunteers
completed psychological questionnaires. Forty-two of the volunteers were
assigned to receive twice-weekly full body UVA irradiation for 3 weeks. The
other 11 received no phototherapy. At the end of the trial, all participants
completed psychological questionnaires. They found that sunbed exposed
volunteers felt significantly more balanced, less nervous, more strengthened,
and more satisfied with their appearance after sunbed use. By contrast, the
controls did not show significant changes of psychological parameters. However,
serum serotonin and melatonin were unchanged.
Another study also found a more relaxed and less tense mood after UV exposure in
sunbeds compared with non-UV exposure.

So Why Do Sunbeds Make You Feel Better?
One thought is that it’s due to endorphin production. Skin cells produce morphine like substances
(endorphins) upon exposure to UV radiation.

the predictors of tanning dependence. Am J Health Behav. 2008;32:451–64. doi: 10.5993/AJHB.32.5.1.
At least one study found blood levels of endorphins are higher after sunbed use,
although not all studies show this.
In keeping with the endorphin theory, patients with the chronic pain condition
fibromyalgia have reported a greater short-term decrease in pain and improved
mood after exposure to sunbeds compared to non-users.

I like to feel better. That’s why I seek UV exposure year-round. In the summer, sun exposure is the most
natural and available option. In the winter, I sometimes go to suntan parlors,
and I sometimes use in home devices, too. If you use sun-tanning parlors, ask
for the older, low pressure, standard sunbeds. They pretty well replicate sunlight.
