Breathing through the Nose Increases Oxygen Uptake in the Blood

Breathing through the Nose Increases Oxygen Uptake in the Blood

Nose breathing is more effective at increasing oxygen uptake than breathing through the mouth. When our nose is blocked, the oxygen uptake in the blood reduces. In a study of individuals who continuously breathe through their noses, arterial pressure of oxygen increased by nearly 10%.
