THROAT SINGING And TEH VAGUS NERVE

Throat singing is a vocal technique in which the voice is produced using deep vibrations within the throat, diaphragm, and thoracic cavity. Unlike operatic or standard singing, which relies primarily on the vocal cords and resonance within the mouth and nose, throat singing utilizes low-frequency resonances and overtones produced in the larynx, pharynx, and chest. It is a characteristic feature of traditions such as khoomei from Tuva and Mongolia, as well as modern musical styles like extreme metal.

Influence on the Vagus Nerve

The vagus nerve is the primary nerve of the parasympathetic nervous system, responsible for regulating breathing, heart rate, digestion, and the body's state of calm.
Throat singing influences this nerve for several reasons:

Deep Vibration: low frequency vibrations resonate within the throat and chest, thereby mechanically stimulating the pathway of the vagus nerve.

Slow, Controlled Exhalation: the act of singing necessitates regulating the outflow of air, which activates the parasympathetic nervous system and induces relaxation.

Diaphragmatic Resonance: it involves deep abdominal breathing, another pathway for vagal stimulation.

Low, Sustained Tones: low pitched, continuous sounds (such as the "OM" sound or a guttural hum) have been documented in studies on vocal toning and chanting as effective stimulators of the vagus nerve and regulators of the autonomic nervous system.

A Simple Throat Singing Exercise to Stimulate the Vagus Nerve

Note: Perform this gently, without straining your throat. The sensation should be one of vibration and relaxation, not pain.

1. Posture and Breathing

Sit with your back straight.

Place one hand on your abdomen.

Inhale deeply through your nose, directing the air down into your belly (diaphragmatic breathing).

2. Base Sound (Low Hum)

Exhale slowly while emitting a low-pitched sound, similar to an "Mmmm", but allow it to vibrate deeply within your chest and throat. Do this for 5–7 seconds per exhalation.

3. Transition to the Guttural Sound

Open your mouth slightly and transform that hum into a low, raspy “Huuuuh”, like a deep yet resonant sigh.

Imagine the air brushing against your throat; do not tense up, simply let it vibrate.

4. Hold and Feel

Sustain the sound for 5–10 seconds, focusing on the vibration in your chest and neck.

Repeat 5 times.

5. Integration

Rest for a few seconds, noticing the sense of calm and the vibrations throughout your body.

You may progressively increase the duration of this practice to 2–3 minutes per day.

With practice, this exercise not only improves vocal technique but also stimulates the vagus nerve, regulates the nervous system, and induces states of calm similar to those experienced during meditation.
