The TherraSauna is a type of FAR Infrared sauna that uses healthy heat to warm the body and not the air around it. Some of the positive effects include enhanced healing of the skin, reducing arthritis pain, and head aches. The way it works is by shooting out infrared heat in wavelengths of 7 - 14 microns. Many clinical studies have been done to show the benefits of exposing a person to this type of heat. The actual patented component that emits healing heat is called a Theramitter. This outputs the same kind of heat that a normal human body would give off. As a result, a human body is receptive to it. 

This Infrared Sauna plugs right into a normal outlet and has some nice quality control functions. You can set the amount of humidity, heat, and water-resistance. The way you consume power with the patented ThereHeat system is efficient at 96% utilization. No other similar system is as high as this. It only takes about 5 minutes for this thing to reach full output and it has a usage life of 10,000 hours, which equals 27 years worth of time.

The final reason why this sauna is such a high quality product is because of the wood its made out of. The wood used is 100% clear non-toxic and brought in from either Canada or Alaska. Other similar saunas will use redwood or cedar, which secretes a toxic gas called Cedrene when heated. It get inhaled or absorbed through the skin and causes negative health effects. You don't want to expose yourself to this.
