Vagus Nerve Humming — 3 min
Three minutes of long, low-pitched humming on the exhale stimulates the vagus nerve via the larynx and ear. Vagal stimulation, parasympathetic activation, a focus reset.
Three minutes of long, low-pitched humming on the exhale stimulates the vagus nerve through the larynx and ear, and the extended exhale is itself parasympathetic. A convenient reset when breath-work alone is hard to focus on.
The protocol
- Style: long, low hums on the exhale.
- Duration: 3 minutes.
- Frequency: as needed.
- Prerequisites: a quiet space.
What you get
- Vagal stimulation via the larynx and inner ear.
- Parasympathetic activation from the extended exhale.
- A fast focus reset when concentration slips.
Why it works
Humming vibrates the larynx, which sits close to branches of the vagus nerve, and the sensation carries through to the ear via the auricular branch. Combined with an exhale that's deliberately longer than the inhale, the practice nudges the autonomic nervous system toward its parasympathetic, "rest and digest" state — the same mechanism behind slow-breathing protocols, packaged into something easier to sustain attention on than silent breath-counting.
Evidence level
Medium. Vagal-afferent stimulation via humming and chanting has reasonable mechanistic and small-study support; treat it as a low-cost daily practice rather than a clinical intervention.
