While breathing in oxygen-rich air in a pressurized tube where the air pressure is increased 2-3 times higher than normal air pressure. This pressure increase shrinks the oxygen molecule, making it possible for your lungs to absorb more oxygen than in normal air pressure. 

Your blood carries this oxygen throughout your body. This helps fight bacteria and stimulate the release of substances called growth factors and stem cells, which promote healing. You body needs a certain amount of oxygen to function but when tissue is injured, it requires even more oxygen to survive. In a one hour hyperbaric oxygen therapy session you are breathing concentrated oxygen while laying in a comfortable reclined position. Your relaxing session gives you time to breath and rest. Many clients sleep, but you are also able to read, listen to music, watch a show or catch up on some work.
