Dealing with a cold is bad enough, but when it leads to a sinus infection, the misery can double. Some researchers have proposed a surprising remedy: humming a tune.
It is well known that reduced airflow plays a major role in sinus infections. Researches reported in the European Respiratory Journal that humming results in a large increase in air to the nasal sinuses. They also found that daily periods of humming might help lower the risk of chronic nasal and sinus infections.
THE BOTTOM LINE
Studies show that humming helps increase airflow between the sinus and nasal cavities, which could potentially help protect against sinus infections.
