Do You Understand How to Reset the Vagus Nerve?

A hot topic right now is the Vagus Nerve Reset.  The vagus nerve, a major player in your nervous system, is getting a lot of attention right now, especially with the trend of “vagus nerve resets.” But what exactly does this nerve do?

What the Vagus Nerve Does

Often called the body’s superhighway, the vagus nerve is the longest and most complex of the cranial nerves. It acts as the primary communication link between your brain and many of your body’s key organs, including your gut, heart, and lungs.

It’s the main nerve of the parasympathetic nervous system, which is responsible for the body’s “rest and digest” functions. According to ClevelandClinic.org the vagus nerve helps regulate crucial involuntary bodily processes like:

  • Heart rate, Heart Rate Variability, and blood pressure
  • Digestion
  • Immune response
  • Mood
  • Mucus and saliva production
  • Speech
  • Taste
  • Urine output.

When you feel anxious or stressed, it’s a sign that your body’s sympathetic nervous system (the “fight or flight” response) is in high gear. This system can interfere with the vagus nerve’s ability to do its job, which is why you might experience a racing heart or an upset stomach when you’re under pressure.

Understanding how the vagus nerve works is the first step to learning how to influence it and promote a state of calm.

There are many science-aligned micro-practices to help calm the vagus nerve.  These simple actions engage the parasympathetic nervous system by leveraging the nerve’s connection to the throat, heart and diaphragm.  Within 2-5 minutes you begin to nudge your system into calm and steadily boost HRV, Heart Rate Variability over time.

Heart Rate Variability is the variation of the time between heartbeats, reflecting the balance between the sympathetic (“fight-or-flight”) and parasympathetic (“rest-and-digest”) nervous systems. A healthy, flexible nervous system results in higher HRV, while stress, illness, and poor lifestyle habits can lower it..

Deep Diaphragmatic Breathing

Utilizing coherent breathing, breathing at a slow, steady rhythm of approximately 6 breaths per minute, will balance the autonomic nervous system and often increase HRV.  The key is slow, even nasal breathing 5 seconds in, 5 seconds out for about 2-5 minutes. 

Here is how to do it:

  • Sit tall, one hand on chest and one on belly.
  • Inhale through your nose for 5 seconds, feeling your belly expand.
  • Exhale through your nose for 5 seconds, softening shoulders and jaw. Make it easier: Use a timer or a breathing app set to 6 breaths per minute.

With this technique, I prefer to use easy pacing music to keep at the right pace. I combine it with an acupressure point to the side of an ear by the neck.  I repeat it on the right opposite side.

The Physiological Sigh

This technique is good for fast downshifting.  Simply take two short inhales through the nose followed by a long, unhurried exhale through the mouth.  Repeat it 5-10 times. This reflexive pattern offloads carbon dioxide and rapidly reduces the physiological arousal. 

Here is how it works:

  • Inhale 70% full, then a quick top-up sniff.
  • Exhale long and slow until fully empty.

Tip: Use this before a meeting, after a tense conversation, or when you notice shallow chest breathing.

Humming or “Om” Toning

Use gentle humming on the exhale for 2-3 minutes.  Humming lengthens exhales and add soothing vibration to the throat and chest, stimulating pathways connecting t the vagus nerve and promoting relaxation. 

Follow these steps:

  • Inhale softly, then hum a steady tone as you exhale.
  • Feel vibration in the lips, nose, chest. Keep it comfortable and quiet.

Variation: Sing a single, low note or chant “Om” slowly for 5–10 rounds.

Cold Splash or Face Dunk (The Dive Reflex)

Briefly exposure your face to either splashing cold water or submerging your face in bowl of cool water for 10 – 20 seconds. This quick cool sensation wakes up the facial cold receptors and the mammalian dive reflex that activates the parasympathetic pathways that slow down the heart and can rase HRV (Heart Rate Variability)

Use these steps:

  • Fill a bowl with cool water and a few ice cubes (not painfully cold).
  • Take a breath, hold gently, dunk your face for 10–15 seconds; repeat 2–3 times as tolerated. OR You could splash cool water across cheeks and under the eyes for 30–60 seconds.

Safety Tip: Avoid this if you have uncontrolled heart beat, blood pressure, or breathing conditions. When in doubt, ask your clinician first.

Gargling or Swallowing Tonic

You will vigorous gargle water or take slow sips of water with deliberate swallows for 30-60 seconds. By using the muscles of the throat and soft palate, you are engaging cranial pathways related by vagal activity.  Repeated practice can help “tone” these reflexes.

Here is how to do it:

  • After brushing, gargle with water for 30–60 seconds.
  • Or take 10–12 slow sips of water, pausing to fully swallow each one.

Pro tip: Taking slow sips and pausing will prevent choking.  Add this to your morning and evening routine for easy consistency.

Diaphragm Reset: Belly-First Breathing

You will be performing a brief, focused diaphragmatic breathing to re-establish belly movement. The benefit of this technique is that the diaphragm has direct relationships with the vagus and abdominal organs, and restoring belly expansion reduces fight-or-flight chest breathing like a panic attack.

Utilize these steps:

  • Lie on your back with knees bent. Place a light book on your belly.
  • Inhale through the nose to lift the book. Exhale to gently lower it.
  • 10–15 breaths, then sit up and keep the same pattern for 1–2 minutes.

Progressive Release: Tense–Relax Scan

A Progress Release is a 90-second head-to-toe sequence of gentle muscle tensing and releasing. When you are alternating tension and release, it sends “all clear” signals to the nervous system and complements vagal practices.

This is what you would do:

  • Starting at the face: scrunch for 3 seconds, release 5–7 seconds.
  • Move to shoulders, fists, glutes, calves, and feet—same pattern.
  • Finish with one long exhale and a soft jaw.

Stacking for a 5-Minute Reset

Don’t be afraid to mix and match and stack the exercises listed above for a total of 5 minutes.

You could do:

  • Minute 1: Physiological sighs (8–10 rounds).
  • Minute 2–3: Coherent breathing at 6 breaths per minute.
  • Minute 4: Humming on the exhale.
  • Minute 5: Cold splash or gargle (choose one).

You are welcome to change it up weekly or daily.

Important to Track Your Progress

Truly, you don’t have to have gadgets to track your progress.  Notice the changes in your body and make notes in a journal.

HRV Proxy

Make note of the HRV by how quickly you are calming down after stress doing these practices. 

Breath Check

With breathing are you noticing that your exhales are getting longer after two weeks?

Body Cues

Pay attention to the tension in your body. Is your jaw less clenched?  Is digestion easier?  Do you have more steady energy.

Smart Watches

From Smart watch information, pay attention for gradual updrift in your average HRV over a two to four week time frame.  Also pay attention to the highest HRV in the mornings with slightly more challenging tasks.  Then use the low – HRV days for lighters loads and extra recovery.

Common Road Blocks

You may forget to do these practices.  You can use anchoring to existing habits like brushing teeth, humming the shower, waking up with cold splashes on your face.  I personally destress with deep diaphragmatic breathing with acupressure morning and night.

At first, you may think this takes too long.  When you get the hang of it, it will become easier and faster. Plus, your body will be responding faster to it.

Remember, the cold splash is not a icy splash. It is a quick action and you will get great benefit from it.

Be Smart and Safe

Everyone has their own fingerprint of health.  If you have cardiovascular, respiratory, or neurological conditions or are pregnant, check with your healthcare provider before cold exposure or new breath practices.

Stop if you feel dizzy, tingling in hands or face, or short of breath. Return to normal breathing and sit or lie down.

Want a 14-Day Vagal Tune-Up Challenge?
