The moist heat experience during your steam therapy treatment speeds up the chemical process in the body. As the pores open up an the millions of sweat glands start to excrete, the body rids itself of toxins. Sweating is such an effective way to detoxify, and why some physicians recommend home saunas to supplement kidney machines. Sweat also draws out lactic acid which causes stiff muscles and contributes to general fatigue. This is why you will feel more relaxed and rejuvenated after a detoxification treatment.
