Tony drove 9 hours to get to the expo. He has had chronic sciatica and was searching for relief. After a 15 minute session, he felt the sauna was working to give him relief and said, “When you are sweating you are detoxing.   He came back after sitting 1 1/2 hours in a seminar (sitting makes the sciatica worse) and said he never thought the far infrared would help with the pain but that it seems to be working!
