Infared Sauna is am amazing technology you can read about it here.
I have had the floor model for about 4 years now and have used it for detox on myself and others.
It is great after an intense Yoga class, run or work out to release the lactic acid and stress build up on the muscles. check out the web site and commit to treating yourself to an Infared sauna. Stop by my place to try it out.
