How humming regulates your nervous system
When you hum, the vocal cords vibrate, producing a gentle mechanical resonance in the nasal cavity and throat. This vibration directly stimulates the vagus nerve, triggering the parasympathetic “rest and digest” response.
Several benefits:
- It automatically prolongs exhalation, slowing your heart rate.
- It increases nitric oxide production in the nasal passages.
- It shifts the autonomic nervous system out of “fight or flight” into a feeling of safety.
