Athlete with knee and shoulder issues gets relief from sauna use

Paul was a college athlete who has had knee and should injuries. He went in the Relax Sauna for 5-7 minutes.
"I felt rejuvenated. I feel more alert more lively. I feel my mental sense of awareness. I feel great.
Tell me about you knee, how did it feel before you got in?
It was a little inflamed because I've been walking around the convention center. I hoped in here, took the pain away. I can totally bend it no problem. When I first got in it was 3/5. I was very surprised. My shoulder too.
I don't even need a coffee any more. I feel alert.
I feel good mentally. I feel positive, rejuvenated."
