Oxygen Therapy blocks the action of harmful bacteria and strengthens the body's immune system. Hyperbaric Oxygen Therapy (HBOT) can disable the toxins of certain bacteria. It also increases oxygen concentration in the tissues. Swelling and inflammation can be greatly reduced. All of the fluids in the body become saturated with life-giving oxygen. Bacteria and most viruses cannot survive in an oxygen rich environment. Detoxification is promoted and wounds/injuries heal more quickly.
