You may have already heard of the vagus nerve in one of your school biology lessons.

It’s the longest nerve in your body and is found right behind where you feel for your pulse.

One of 12 cranial nerves, this super nerve starts in the brainstem and runs all the way to your abdomen, cutting through your heart, esophagus and your lungs.

Known as “cranial nerve X”, the nerve is part of your involuntary nervous system, the system that directs your unconscious body activity, such as keeping your heart rate stable and ensuring you digest food properly. It tells the body to heal itself, essentially.

The nerve moves around your body (like a vagabone, hence the name) sending out tiny fibres to your organs, such as your heart, lungs, liver, pancreas, and intestines. The vagus nerve is essentially controlling your parasympathetic nervous system, responsible for stimulating your “rest and digest” activities.

But the most interesting thing about the vagus nerve is the new research that has revealed its link with treating chronic inflammation, which can lead to high blood pressure, digestive issues, and migraines. Known as the missing link, the nerve may be able to treat these issues without medication! Here’s how:

Vagal Tone

Vagal tone is the control the vagus nerve has over your heart rate. Recent studies have revealed that vagal tone is important in order to activate the parasympathetic nervous system. By tracking your heart rate in addition to your breathing rate your vagal tone can be measured in a person.

When you breathe in your heart usually speeds up slightly, and when you breathe out your heart rate slows down a little. To determine your vagal tone, you need to establish the difference between your inhalation heart rate and your exhalation heart rate. The bigger the difference, the higher your vagal tone will be.

High or low?

Having a higher vagal tone is a good thing. It means you are more likely to be able to relax your body after suffering from stress more quickly, and your internal systems probably function better, such as:

  • Sugar regulations
  • Reduced risk of stroke and cardiovascular disease
  • Lower blood pressure
  • Better digestion
  • Fewer migraines
  • Lower depression
  • Less stress and anxiety

Scientists have discovered that the vagus nerve is monitoring and responding to your body. It initiates responses to any inflammation, all of which affects your mood and your ability to cope with your body’s reactions.

Low vagal tone

If you have a low vagal tone you are more susceptible to heart problems, strokes, diabetes, depression, and inflammatory conditions such as rheumatoid arthritis, inflammatory bowel disease, lupus, and endometriosis.

However, a number of researchers have discovered that by stimulating the nerve using electrical current you can increase your vagal tone, and improve your resilience to these problems.

However, there are ways you can improve your vagal tone yourself:

1. Hum. It may sound bizarre, but humming stimulates the nerve because it is connected to your vocal chords. Try it!

2. Speak. Speak more and you will raise your vagal tone through your vocal chords.

3. Coldwater. While there is more research to be done on this technique, there has been evidence to suggest that by splashing cold water on your face you stimulate the vagus nerve.

4. Breathe Deeply. Take long, deep breaths and use your diaphragm to stimulate your vagus nerve.

5. Yoga. The relaxed, concentrated breathing practices of yoga can increase to your vagal tone levels.

6. Meditate. A study in 2013 reported that meditation and thinking positive thoughts can have a positive effect on your vagus nerve.

7. Improve gut health. One of the many positives of having a healthy gut is that it increases your vagal tone levels. It works by creating a loop of health from your gut, through the nerve and back. Try probiotics as a healthy bacteria supplement.

Adjust your daily routine to improve your vagal tone and stimulate your vagus nerve, it’s so simple but so effective. It’s time to take control of your nerves!

    Check the 2010 study references:
    Gaia Vince made a BBC Radio 4 programme about this topic, first broadcast in November 2014.

    Kevin Tracey wrote about his work in the March 2015 issue of Scientific American.

    A 2012 review of neural reflexes in inflammation and immunity by Tracey.

    And a 2002 review by Tracey in which he predicts vagal modulation could be used to treat inflammatory disease.

    Barbara Fredrickson and Bethany Kok’s research on positive emotions and vagal tone.

    I woke up once with a huge pressure in my upper thigh and lower abdomen and had to pee super bad. Turns out my bladder was so full it was pressing on the nerve and when I peed it released the pressure.. I got major nausea tunnel vision and bam woke up on the floor not knowing what happened. Doctor says it usually happens to old men when they pee, I’m a 24 yo female. Fml hahaha

    I have had luck by massageing my head to stimulate the vagus nerves.And if that don”t work I take two acetaminophens. When I was young I tried placing my head in a vise. Problem there is do not let your wife help if she is mad at you.

    I have gastroparesis which means I don’t digest food properly and it causes very frequent vomiting and nausea. It is truly debilitating and they say it is caused by my vagus nerve not working. Just wondering if anyone else has this?? It is pretty rare but I’ve noticed I have every symptom (health issue) listed in the article. Can you stimulate a paralyzed nerve?

      I am not a doctor and yes definitely talk to a doctor who could refer you to a physical therapist. You can stimulate a paralyzed nerve to get it to “remember or wake up what it used to do” using “TENS”
      (Transcutaneous Electrical Nerve Stimulation). Supposedly they have ones at the store that are “behind the counter” I wouldn’t buy any other those especially if you are not sure of the direct cause of the problem.

    I have been suffering from ‘Phantom Nausea’ for 13 months and I can not figure out why! Had an EGD…nothing showed up….I call mine ‘episodes’. I can feel my blood pressure dropping, I have to sit down and put my head low, the nausea comes whenever it wants to and it lasts as long as a Labor Contraction.
    I do not vomit, I just have SEVERE nausea, it is painful…

    My son was completely disoriented all of a sudden after a tooth extraction he almost lost his life, he lost his voice like something caught his throat he could not talk could not walk, was wobley, his whole body was jerks, once it felt like something was jumping in him, he could not eat, lasted a week, now completely normal, this is the second time it happened to him, is this a medical or spiritual thing
