It turns out that: the question of nose breathing vs mouth breathing has been extensively studied and nose breathing is clearly superior.The nasal route optimizes the intake of oxygen and expiration of carbon dioxide,contributing to a regular, efficient breathing rate and improves lung volumes.By contrast, mouth breathing results in over-breathing elevating blood pressure/heart rate, with mild chronic oxygen deficit
