Oxygen Therapy
Oxygen therapy involves inhaling oxygen at a higher concentrations than in the air. This increases the oxygen concentration in blood, accelerates blood circulation, and distributes more oxygen to the tissues.
The positive effects are manifested by accelerated cell growth and regeneration, thus improving injury healing and generally slowing down their ageing process. It also helps strengthen one's immune system and fight infections, increases physical fitness, and accelerates regeneration after physical stress.
This method features no side effects.
