Carol uses it every day.  Her husband was skeptical at first and said they didn’t need such a thing.  She insisted he sit in the sauna one time when he was in pain from doing yard work and after using it he told her, “Whatever you do, do not get rid of that sauna!”  It took way his pain that quickly.  Anytime you get cold or feel you are coming down with something you pop in.  It only takes 15 to 20 minutes. If you want to have a really nice sleep you can get in it for 10 minutes before bed and not get really hot, just nice and relaxed, and have a nice deep sleep.  She encourages people to try it and says, “You will love it.”
