Vagus Nerve: 7 easy ways to access its powers

Written by

Deborah Freudenmann BHSc

Our vagus nerve has been getting increasingly more attention as of late… 

The question is why? 

Your autonomic nervous system is the branch of your peripheral nervous system which regulates the function of your internal organs like your heart, stomach, glands, smooth and cardiac muscles – all the things you do not consciously control.

The effects on your organs, muscles and glands are by no means consistent. At any given time whether you happen to be totally relaxed or completely freaking out your autonomic system is constantly making involuntary fine-tuned adjustments to your body.  To understand what type of adjustments it is making to the body depends on which part of your autonomic nervous system is in charge at that moment!

Your autonomic nervous system has two divisions which serve the same organs but create opposite effects in them.

Impacts of trauma

One of these divisions is called our sympathetic nervous system or “fight-or-flight”– this division is dedicated to activating you and preparing you for survival. This fight-or-flight response is known to increase heart rate, increase breath rate, decrease depth of breath, dilating the pupils, driving blood flow towards muscles in our arms and legs and away from the liver and digestive tract.

The other division is called our parasympathetic nervous system or “rest and digest” and essentially allows us to relax and recover. Shifting the focus towards remaining calm, decreasing our heart rate, decreasing our breath rate, taking deeper breaths, and driving blow flow away from our limbs and towards internal organs, which allow our bodies to recover, digest and reproduce.

Our parasympathetic nervous system is largely operated by our vagus nerve – which originates from our brainstem and runs through our entire body. Our vagus nerve is unbelievably intricate and regulates the controls of our heart, gut and lungs. It also branches out to our liver, stomach, pancreas, gallbladder, spleen, kidneys, reproductive organs and some muscles.

So as you can imagine, if our vagus nerve is dysfunctional it can cause some pretty significant health issues and has been associated with a diverse range of diseases.

Unfortunately, most of us are dominated by our sympathetic nervous system. We live in a world obsessed with keeping up – putting us all under considerable amounts of stress, constant high pressure situations, and very little down time.

The issue with this is that our bodies are not able to distinguish between the everyday stress we face in our modern world versus the stress we face when we are in a life threatening situation. For example, (and thankfully) our body switches into its “fight or flight” when we are in imminent physical danger such as standing in front of a lion or bear. But this also means we switch into “fight or flight” when our university lecturer discusses an exam we are about to sit or when we hear the stern “we need to talk” line from our spouse. Eeek!

So with this in mind, our bodies are under a constant and consistent level of “stress” – causing us to produce high levels of inflammation and impacting most of our bodily systems.

As a health coach it is important to educate your clients about the importance of activating their vagus nerve, how they can achieve it and start dominating our parasympathetic nervous system.

We need to STOP, rush less, plan less, slow down and be less busy.

And instead help our clients include more resting, more reading, more me time, more boundaries, more singing, more laughing, more humming, more…

Here are our TOP 7 practices for vagus nerve stimulation

1. Cold showers

When we expose our bodies to something cold – this first causes an increased sympathetic nervous system response but is quickly halted after we acclimatize to the cold. In other words, our parasympathetic nervous system increases – which is mediated by our vagus nerve. Cold application to activate your vagus nerve can include a cold shower, splashing cold water on your face or drinking cold water.

Mäkinen, T. M., Mäntysaari, M., Pääkkönen, T., Jokelainen, J., Palinkas, L. A., Hassi, J., … Rintamäki, H. (2008). Autonomic nervous function during whole-body cold exposure before and after cold acclimation. Aviation Space and Environmental Medicine, 79(9), 875–882. https://doi.org/10.3357/ASEM.2235.2008

 
2. Singing, humming and chanting

Humming, chanting and singing all increase heart rate variability. Heart rate variability is a measure of the balance between the parasympathetic nervous system, which decreases the heart rate and increases the relaxation response via the vagus nerve. Singing produces slow, regular and deep respiration causing a pulsating vagal activity. Singing can be viewed as initiating the work of a vagal pump, sending relaxing waves through the choir. Singing at the top of your lungs also makes you work the muscles at the back of your throat – activating the vagus nerve. All the more reason to sing in the shower, or literally anywhere!

Khoff, B. V., Malmgren, H., Åström, R., Nyberg, G., Ekström, S. R., Engwall, M., … Jörnsten, R. (2013). Music structure determines heart rate variability of singersmusic structure determines heart rate variability of singers. Frontiers in Psychology, 4(JUL), 1–16. https://doi.org/10.3389/fpsyg.2013.00334

 

3. Yoga

Yoga is a parasympathetic activation exercise that promotes vagal tone. Similar to singing, yoga breathing and guided breathing have beneficial effects on switching to our “rest and digest” state. A 12-week yoga study was conducted to assess shifts in mood and anxiety levels vs a group that did walking exercises. The yoga group showed a significant improvement in mood and decreased anxiety during the 12-week intervention compared to the walking group. Such observations support the hypothesis that part of the effect of yoga is vagal activation by slower breath rates often used during yoga posture techniques, but not during walking.

Journal of Alternative and Complementary Medicine, 16(11), 1145–1152. https://doi.org/10.1089/acm.2010.0007

 

4. Deep breathing exercises

Conscious breathing is the key to stimulating your vagus nerve. Slowing down breathing – Slowing down exhalation phase promotes dominance of the parasympathetic system. Through deep breathing we improve or vagal tone which has a strong effect on heart rate variability.

5. Laughter

Laugher has been shown to increase heart rate variability thus decreasing the heart rate and increasing the relaxation response via the vagus nerve.

“Empirical research on laughter supports this folk wisdom, showing that laughter can have a variety of psychological and physiological health benefits, including improved coping skills, enhanced mood and feelings of well-being, decreased discomfort, and a higher pain tolerance as well as reduced neuroimmune and stress markers. Considering the variety of health benefits, humor might be an excellent clinical intervention.”

6. Pulsed Electromagnetic Field therapy

A study has found that magnetic fields are capable of stimulating the vagus nerve. The effects of PEMF on the human autonomic nervous system were found to be significant using heart rate variability measurements. In a study on 30 healthy men, pulsed electromagnetic field (PEMF) therapy increases heart rate variability and vagus stimulation.

Grote, V., Lackner, H., Kelz, C., Trapp, M., Aichinger, F., Puff, H., & Moser, M. (2007). Short-term effects of pulsed electromagnetic fields after physical exercise are dependent on autonomic tone before exposure. European Journal of Applied Physiology, 101(4), 495–502. https://doi.org/10.1007/s00421-007-0520-x

 

7. Acupuncture

Acupuncture has been demonstrated to directly or indirectly modulate parasympathetic nervous system activity through the vagus nerve. Acupuncture influences vagus nerve activity, whether directly through direct stimulation of its auricular branches or indirectly through reflex activation. Acupuncture has neuromodulatory effects on the autonomic nervous system, which can be used clinically to normalize autonomic balance and potentially favorably alter the course of disease.

Da Silva, M. A. H., & Dorsher, P. T. (2014). Neuroanatomic and clinical correspondences: Acupuncture and vagus nerve stimulation. Journal of Alternative and Complementary Medicine, 20(4), 233–240. https://doi.org/10.1089/acm.2012.1022

There are countless other ways to increase our vagal tone including – tai chi, massages, specific supplementation, activation of specific muscles, chewing food properly, fasting, light exercise etc. These top 6 practices for vagus nerve stimulation are simple and uncomplicated and can be implemented into your clients (and your own) daily routines.

What are your favorite ways to active the vagus nerve?

  1. Very interested in your article because for some time I have been studying the community, social and psycho physical effects of walking the Chartres labyrinth with many points of transition that stimulate the vestibular labyrinth and triggers a parasympathetic response. A symbolic walk that hase been around since the Bronze Age. and built into medeival Cathedrals and still available to day must be more than a metaphysical journey and a mindfulness meditation but is yet to attract serious research.

  2. is an atrial tachycardia a vagus nerve problem…. particularly if it’s paroxysmal, and in fact is infrequent as well?

    if it is, then maybe there’s a nutrient deficiency in play, since celery has a calming effect … starting the green stalks has slowed an over 200bpm down to 160, and the paler heart stems has been seen to calm the pace down to under 3 digits…

    As stress builds and coping takes full attention, there is a sensation of heart ‘tripping’ and then it races to keep up with some sense of shortfall… sortof….. maybe it’s not a vagus nerve issue, but i noticed that Linus Pauling was prescribing C and lysine for heart problems and coincidentally, celery is [relative to other foods] on the high side per serving…. more to puzzle over.

    With a racing heart the oxygenation seems lessened so that’s one thing i’ve tried when i didn’t have the pale stalks… not as effective…. and i didn’t know what to do with the pemf as the chart above shows different spinal points for parasympathetic and sympathetic control of the heart… nor have i tried acupuncture.. not compatible with racing heart and stress…. ttyl

  3. Hello Deborah,
    Thank you for this important part of education your company provides. I am using the old and faithful Curatron 2000 PC with plenty of protocols available. I wonder if there is any of them recommended for stimulating the Vagus Nerve system.
    Thank you,
    Bogdan

    1. All Pemf frequencies recharge your cells. Because all cells need to be protected and energised the program 0,4,7,9 cover all frequencies. Just use regularly for the whole time of the program.

  4. Dear Friends ~
    Always remember this:
    2400 Years ago Hippocrates said:
    Give me the Power to produce Fever
    and
    I will cure ALL Disease !!
    +
    “I have not seen any flu yet that was not cured or markedly ameliorated by massive doses of vitamin C.”
    (Robert F. Cathcart, MD)

    1. Yes this is by far the best method to boost your immune system and kill or flag all pathogens in your body.

      Unfortunately is hyperthermia still not regarded as the best home remedy of all.

  5. My favorite ways to active the vagus nerve is by using NADA (ear acupuncture), humming/meditation, Pemf 120, and swimming in the cold ocen in Iceland.
