I have been feeling overloaded with toxicity lately, and it has been especially horrible on my brain and sleep. I am looking to find a small, inexpensive sauna unit. I have already tried the Biomat ($1600--very expensive!) and not very impressive considering all the hoopla around it. I have also tried to set up a sauna in my bathtub using brooder lights and mylar sheets over and around the tub to enclose the heat. This was recommended by a FB friend. But it required a lot of effort to set up and was not effective enough. Now I am looking into these type of sauna units. I don't know if they are any good...? Does anyone have any experience with them? This one is only $175 and has lots of good reviews. http://www.amazon.com/Infrared-Portable-Foldable-Sauna-Detox/dp/B002POAYDW Any useful input would be appreciated. Thanks.
