The Vagus Nerve and Sound

· Calm & Stress Relief · Ressonia Team

The body's rest switch

The vagus nerve runs from brainstem to gut. When it's active, your heart rate variability rises, digestion improves, and the nervous system settles into "rest and digest" mode.

Sound as a vagal trigger

Research from the Frontiers in Human Neuroscience journal (2020) shows that humming, chanting, and low-frequency tones (under 150 Hz) stimulate vagal tone through vibration of the larynx and inner ear.

Try this

  1. Find a quiet room.

  2. Press play on a 174 Hz or 285 Hz Solfeggio tone.

  3. Breathe slowly for ten minutes.

Notice the shoulders. Notice the jaw. The body knows before the mind catches up.
