Your Nose Knows Nitric Oxide

Nitric Oxide is created in your sinuses. One of the best ways to get a healthy dose of Nitric Oxide is to simply hum and inhale through your nose. The humming creates a vibration of the sinus cavities which in turn creates nitric oxide.
Here’s an example finding from a study:
“We report that NO in humans is produced by epithelial cells in the paranasal sinuses and is present in sinus air in very high concentrations, close to the highest permissible atmospheric pollution levels.” You can read more here.
Here’s a study about humming and nitric oxide:
“Ten healthy subjects took part in the study. Nasal NO was measured with a chemiluminescence technique during humming and quiet single-breath exhalations at a fixed flow rate. NO increased 15-fold during humming compared with quiet exhalation.”
