Thank you to all for your comments.
I wish I felt my pale was beautiful .......

so despite knowing all the "bad" things - I went ahead anyway! I have just completed my 5th session and am looking pleasantly (but lightly) tanned. The first 2 sessions left me quite sore but I am liberal with soothing lotions twice a day. I have 5 more sessions to go (paid for) and then I would like to keep it up about twice a month as I don't really want to go very dark.
As far as cleaning the bed - I'm fanatical about that and clean it thoroughly before as well as after.
The one thing that bothers me just a little is my claustrophobia and dread of being in enclosed spaces. I have coped though and keep telling myself this is my choice.
I feel healthier simply because I don't look like a ghost tinged with blue!
