there is 2 types.
rooms that you can go sit in
then a sauna suit.
the suit you can put on and go work out or just sit and lose weight.
and the room is just a room that you sit in.
You lose weight by sweating off the pounds. Saunas expel water and do not necessarily expel fat deposits. Also, any weight lost through a sauna room/suit will be regained quickly. Therefore they are not a permanent weight loss solution.
