Why nasal breathing is important: 80% More Oxygen: Nasal breathing allows for more efficient gas exchange in the alveoli (air sacs in the lungs), leading to better oxygenation of the blood. Athletic Performance: This is because nasal breathing optimizes oxygen uptake and reduces the chance of injury. Mental Benefits: Nasal breathing is commonly linked to relaxation techniques and meditation. It has the potential to stimulate the parasympathetic nervous system, causing relaxation and lowering stress levels.
