Sherry Rogers was one of the first to point out to Americans that a solution to this toxic world that we live in could be .... Far infrared Saunas! 

Before this classic book, many others have pointed out in their books that we live in a toxic world, and that toxemia is the cause of most (or all) disease. 

Ever since Dr. Roger's book, others have added their 2 cents, and also pointed out so many medical benefits that Far Infrared Energy can provide.
