What about sunbeds/tanning ?

I live in the UK and now that winter is on its way. most of the mornings are dark and when I come out of work about 6pm, it is dark by then too.

I have noticed that I feel so so much better after being in the sun, it helps my skin dramatically and makes me feel so happy. Would it be OK to try and comprimise and use tanning beds when I can?

What does everyone think?
