During humming, the gas exchange between the nasal passages and the sinuses is 98 percent, almost a complete exchange. During normal exhalation, without humming, the gas exchange rate is only 4 percent.
Poor gas exchange and poor circulation in the sinus cavities create a good environment for bacterial growth. Researchers suggest that daily humming could help reduce the incidence of sinusitis and upper respiratory infections.
