Humming Can Ease Sinus Problems

Some researchers have proposed a surprising preventative measure for sinus infections -- humming.

Sinus infections often occur when the lining of the sinuses becomes inflamed, trapping secretions and leading to pain and congestion.  One way to keep them healthy is to make sure they have enough ventilation by keeping air flowing smoothly between the sinus and nasal cavities.

The New York Times reports:

“[R]esearchers examined this by comparing airflow in people when they hummed and when they quietly exhaled. Specifically, they looked to see if humming led to greater levels of exhaled nitric oxide, a gas produced in the sinuses. Ultimately, nitric oxides during humming rose 15-fold.”
