After your activity during the day, the body expels toxins and harmful substances through sweat. Muscles also produce lactic acid because of the energy consumed while working. The steam chamber usually allows toxins that are thrown out of the body by sweat but cannot be removed from the body to be in a warm environment after exercising. When you are in the steam chamber, your blood flow accelerates, which means that the lactic acids accumulated in the muscles after the activity break down by taking oxygen and your body begins to rest.
