I don't. I am very fair skinned and burn really easily. I went once and was in for about 2 minutes and ended up with sunburn
Never went back.
I do need to invest in a sunlamp of some sort though because apparently I'm not getting enough Vitamin D. My blood levels are less than 1/2 of what they should be and because of that I'm having a whole lot of bone pain and have to take a high dose prescription vitamin. A sunlamp might benefit me but I'm afraid of getting burned again.
