What length of time should one us a sauna for?
20 mins? or can one be in it longer?

I decided to use the sauna at my local ymca the other day and I thought I could tell a difference. Now I plan on using it everytime I go there. It's just a small room with some kind of metal heater in there (looks like a air conditioner).

btw Russ I was reading the old messages about sauna's and you mentioned you might be getting one (did you ever get one?)

2 years ago~ I remember I paid to have a few treatments using a oxygenation sauna type of thing. Supposedly is really good for you. I didnt notice much but I still had my fillings in at the time so who knows.
