The vagus nerve is concerned in almost each physiological motion within the human physique and harnessing its energy can have a direct and dramatic influence in your well-being.
Metaphors abound for the vagus nerve:
- The superhighway of your physique, transporting very important data between your mind and the remainder of your inner organs;
- A symphony conductor, directing how briskly or gradual, loud or quiet your nervous system will likely be at any given time;
- Air site visitors management, monitoring a large number of shifting elements to ensure all the physiological airplanes fly safely and effectively to their vacation spot.
In a time once we all converse the common language of hyperbole, it might be simple to dismiss this vagus speak as simply one other passing development from a wellness tradition that promotes and discards the subsequent! massive! factor! for sport. (Actually.)
However, right here’s the deal. Physicians way back to the Roman Empire1 have been grappling with how the vagus nerve impacts bodily operate. We’ve now realized that easy motion and breath workouts may be performed at dwelling to manually stimulate the vagus nerve in instances of stress to set off the physique’s pure leisure response. And for sufferers with situations starting from epilepsy to rheumatoid arthritis to Crohn’s illness, digital vagus nerve stimulation is providing hope and exhibiting long-term outcomes. The ability of the vagus nerve lies in its capability to influence bodily and emotional situations which have confirmed to be troublesome to deal with with conventional drug and medical interventions. When individuals run out of choices—for medical issues or stress administration— they discover their technique to the vagus, and understand the facility this one a part of our anatomy has over your entire system.
The hype is now consensus; the way forward for medication and self-care will likely be interwoven with our understanding of the vagus nerve and the way it works.
However First, What’s the Vagus Nerve?
The vagus is the tenth cranial nerve, originating within the mind stem and touring by the face, neck, lungs, coronary heart, diaphragm and stomach, together with the abdomen, spleen, intestines, colon, liver, and kidneys.2 Vagus is Latin for “wanderer,” an applicable identify for the longest cranial nerve within the physique. The vagus nerve is intricately linked to temper, immune response, digestion, and coronary heart price.3
Why is everybody speaking concerning the vagus nerve proper now?
Perhaps you realize a bit bit concerning the vagus already, or maybe you’re studying about it for the primary time. Now that it’s in your radar, you’ll begin to discover it in all places, from podcasts to Fb teams to mainstream information articles. Marriage and Household Therapist Justin Sunseri launched The Polyvagal Podcast, a present about all issues vagus nerve, in February of 2019 and rapidly constructed an viewers of hundreds every month alongside his co-host Mercedes Corona. “I felt a compulsion to do it,” says Sunseri. “I actually awoke one night time at 4 within the morning and the phrases Polyvagal Podcast have been pounding in my head. I knew the data can be actually good, however I had no concept what the larger image can be.”
Lisa Elliott is an aerial acrobat in Seattle who found the vagus nerve after a near-death expertise from an aortic dissection. She began the Vagus Nerve Research Group in her front room with six associates in 2015, and it’s morphed right into a thriving Fb group with nearly 9 thousand members finding out the vagus collectively. “Once I first began finding out it, I used to be within the vagus nerve as a discrete anatomical construction,” says Elliott. “What is that this factor that may make a giant distinction in continual diseases? However over time, I got here to see it as an anatomical map that may lead us to a brand new mind-set about our our bodies and beings, our feelings, and our interplay with the setting.”
Digital Vagus Nerve Stimulation (VNS)
On the medical entrance, Dr. Kevin Tracey is a neurosurgeon who has performed groundbreaking work within the discipline of bioelectrics, the place a small digital system is implanted beneath the pores and skin of a affected person’s chest to ship electrical impulses to the vagus. He revealed a research in 20024 about mice with strokes, revealing that vagus nerve stimulation turned off the physique’s manufacturing of tumor necrosis issue (TNF), a molecule produced by the immune system throughout an inflammatory response that, when regulated, is sweet for the physique, however in extra can injury organs, trigger blood strain to drop, and result in septic shock.5 This prompted a medical trial utilizing VNS on rheumatoid arthritis sufferers6 with excessive ranges of TNF that precipitated debilitating ache. On the finish of the forty-two day research, the TNF ranges of research individuals have been almost the identical as non-arthritic sufferers. Their ache was nearly gone, joint swelling was decreased, and mobility had returned. Dr. Tracey has additionally had success with Crohn’s illness sufferers, and sees a future when ailments like Alzheimer’s, most cancers, diabetes, and hypertension may be handled with bioelectronics. VNS has been permitted by the FDA to deal with epilepsy since 1997, and melancholy since 2005, however every thing else proper now’s within the medical trial phases. Along with Dr. Tracey’s work, there are research being performed on the influence of VNS on diabetes, stroke restoration, glucose metabolism, and lots of others around the globe.
Whereas researchers and the medical institution wade by prolonged medical trials and FDA approval processes, the excellent news is that it doesn’t require a surgical implant to influence your vagus nerve.
Guide Stimulation of the Vagus Nerve
Bodily therapist and purposeful handbook therapist Gregg Johnson makes use of his palms to do handbook work on the vagus, and trains different practitioners to do the identical at his Institute of Bodily Artwork in Colorado. He’s been a bodily therapist for 50 years, however stumbled into an curiosity within the vagus nerve 5 years in the past when he had a pupil who had hypertension and an elevated coronary heart price, and was on the lookout for a technique to keep away from happening long-term medicine. Johnson palpated (examined along with his palms) the neck, and will really feel that the vagus nerve was in stress. “This was the primary time I had selectively, consciously palpated the vagus nerve,” says Johnson. “All the sudden, as every thing began enhancing in mobility, his coronary heart price normalized and he began feeling like he hadn’t for months. And that night time when he examined his blood strain it had returned to regular.” Since then, Johnson has used handbook vagus nerve stimulation to assist sufferers with irritable bowel syndrome, kidney issues, and fertility points, simply to call just a few.

This myofascial self therapeutic massage exhibits each handbook hand and soft-tool palpation.
There are a selection of issues you are able to do with breath and motion by yourself at dwelling to manually stimulate the vagus nerve. However to know how, first it helps to know a bit bit extra concerning the anatomy and performance of the vagus nerve itself.
Vagus Nerve Perform
The vagus nerve is a part of the autonomic nervous system, the physique’s unconscious management system that helps regulate our inner organs to optimize well being, progress, and restoration, an idea often known as homeostasis.7 The autonomic nervous system is split into two branches— the sympathetic department, which mobilizes you for motion (the “on” change); and the parasympathetic department, also known as the rest-and-digest state (the “off” change). The vagus nerve resides within the parasympathetic department of the autonomic nervous system. A lot of our understanding of how the vagus features inside the parasympathetic department, and our capability to influence it by breath and motion, may be traced to Dr. Stephen Porges and the introduction of his Polyvagal Idea in 1994.
Autonomic Nervous System: the a part of the nervous system that unconsciously controls bodily operate, together with issues like coronary heart price, respiratory, and digestion. There are two branches of the Autonomic Nervous System:
- Sympathetic: your physique’s ON change, supporting mobilization for motion
- Parasympathetic: your physique’s OFF change, supporting leisure
The Polyvagal Idea
The Dorsal Advanced and Shutdown
Dr. Porges recognized two pathways of the vagus nerve. The primary pathway, the dorsal advanced, is left over from our pre-mammalian, historic vertebrate ancestors. It’s typically known as the sub-diaphragmatic department of the vagus, as a result of it originates within the mind stem and provides nerves to the visceral organs beneath the diaphragm, together with the abdomen, liver, spleen, kidneys, gallbladder, urinary bladder, small gut, pancreas, and ascending and transverse elements of the colon.8 It’s unmyelinated, which implies it lacks a myelin (fatty) sheath, and consequently transmits data slower than a nerve that’s myelinated. When people or different mammals sense they’re in grave hazard, a surge in dorsal exercise may end up in system shutdown, together with a drop in blood strain, with a possible for fainting or state of shock.9 The dorsal vagal response is referred to in shorthand as shutdown.
The Ventral Advanced and Security
The second pathway of the vagus nerve is the ventral advanced. It shaped as we advanced from historic reptiles to mammals, and originates within the mind stem within the nucleus ambiguus, a bunch of motor neurons linked to the muscle groups integral to speech and swallowing, such because the taste bud, pharynx, and larynx.10 The ventral vagus is the first regulator of the center price, and muscle groups within the face and head. This newer ventral vagal path is myelinated and transmits data a lot sooner than the dorsal vagal path. It’s what’s generally known as our protected and social state, and advanced to offer a social engagement system, which was crucial to ensure that mammals to coexist, work in group, and reproduce. Individuals in a ventral vagal state are typically engaged on the planet, and open to connecting and cooperating with others.
Between the event of the dorsal vagal path and ventral vagal path, the sympathetic department of the nervous system shaped, permitting for mobilization in instances of stress. That is most also known as the fight-or-flight response.
Dorsal Vagus: The oldest a part of the vagal advanced, left over from our pre-mammalian historic vertebrate ancestors. A dominant dorsal vagus ends in a shutdown state.
Ventral Vagus: The latest a part of the vagal advanced, developed throughout our evolution from reptiles to mammals. A dominant ventral vagus presents as a sense of security and social engagement.
Sympathetic: This a part of the nervous system developed between the Dorsal and Ventral vagal complexes; helps mobilization by rising blood move all through the physique.
Polyvagal Idea identifies how these three neural (of or referring to nerves or the nervous system) circuits— the dorsal vagal, sympathetic, and ventral vagal— are concerned in evaluating our surroundings and reacting to cues of security or menace. There are three organizing ideas of the polyvagal principle11:
The autonomic nervous system responds to cues within the setting in a specified and predictable approach. Both so as from the oldest to latest neural circuits (dorsal, sympathetic, ventral), or the latest to oldest (ventral, sympathetic, dorsal).
It is a idea coined by Dr. Porges, and describes how our autonomic nervous system subconsciously evaluates and responds to cues of security or hazard in our surroundings. “Detection with out consciousness,” Dr. Porges says. The vagus has greater than 100,000 nerve fibers, and communicates bidirectionally between the mind and the physique, with 80% of the fibers speaking from the physique to the mind, and the opposite 20% speaking from the mind to the physique.12 So, that “intestine feeling” you’ve felt earlier than— that’s neuroception. It’s your physique having what quantities to a “sixth sense” second, and speaking that data to your mind.
That is the mutual regulation of physiological state between people.13 One instance Dr. Porges makes use of for co-regulation is the connection between a mom and her child. If a mom is calming her youngster and the kid responds by enjoyable and vocalizing sounds of contentment, this has a reciprocal impact of calming the mom. If the toddler continues to be upset and doesn’t reply to the mom’s try to settle her, the mom can even get upset. Dr. Porges calls this our “organic want to attach.”
The Polyvagal Ladder
Deb Dana, writer of the e book The Polyvagal Idea in Remedy, created the idea of the polyvagal ladder as a visible metaphor for a way we expertise physiological change as we transfer by the three neural circuits of the autonomic nervous system.
On the prime of the ladder is the ventral vagus, the place the emotions are prone to be security, consolation, and engagement on the planet round you. You’re typically feeling content material, typically missing in acute fear about something.
Just under the ventral vagus on the ladder is the sympathetic state, the place you progress to for mobilization in the event you detect danger. This might be one thing comparatively small, like receiving a obscure e mail request for a gathering out of your boss that causes you to surprise in the event you’ve performed one thing flawed, or one thing as horrifying as listening to a window break in your home in the midst of the night time and worrying that you’re about to change into a sufferer of a house invasion. In each circumstances, your coronary heart could begin beating sooner, your palms may sweat, and your thoughts could race as you are worried about what might occur subsequent.
On the backside of the ladder is the dorsal vagus, the place shutdown happens. Within the instance of the e-mail out of your boss, if it seems you have been known as into the workplace and fired, you’d probably transfer down the ladder from sympathetic to dorsal state, and shutdown may appear like excessive disappointment or a bout of melancholy. Within the damaged window instance, if it grew to become clear rapidly that you’re about to be a sufferer of a house invasion, shutdown might contain fainting or going into shock as a approach to your physique to guard you from a doubtlessly catastrophic bodily confrontation.
In each situations, it’s potential to maneuver up the polyvagal ladder as a substitute of down, relying on the circumstance. Within the instance of the e-mail, in the event you went to the assembly together with your boss in a sympathetic state, coronary heart racing and palms sweating, and it seems it was a minor request a couple of venture, you could possibly rapidly transfer again up the ladder into the protected and social ventral state, relieved that your fears about being fired have been misplaced. And the identical is true within the damaged window instance. When you uncover it wasn’t a damaged window in spite of everything, however as a substitute a tv that was left on with the quantity up very loud, you’d probably bounce rapidly up the ladder to ventral vagus, relieved that you just and your loved ones aren’t in peril in spite of everything.
Hybrid States of the Polyvagal Ladder
There are situations the place two of the three neural states are mixed. Stanley Rosenberg, writer of Accessing the Therapeutic Energy of the Vagus Nerve, calls these “hybrid states.”14 The fourth state combines the ventral vagal (protected and social) and sympathetic (mobilization) to create mobilization with out worry. Examples of this could be going to a zumba class, enjoying tag together with your youngsters, or participating in a pleasant competitors on the basketball court docket with associates. The fifth state combines the ventral vagal (protected and social) with dorsal vagal (shutdown) to create immobilization with out worry. This creates a sense of calm and security, and examples might embody mendacity nonetheless with a trusted companion after intimacy, or cuddling together with your sleepy youngster earlier than bedtime.
When you’re caught in a dorsal state and really feel such as you don’t have any get-up-and-go, breath might help.
How To Transfer Between States With Breath
Until you’re in a hybrid state just like the examples talked about above, which incorporates the protected and social emotions of the ventral vagus advanced, being caught in a sympathetic (fight-or-flight) or dorsal (shutdown) state may be draining to take care of— mentally, emotionally, and bodily. When you’re locked in a sympathetic state, you may really feel such as you’re continually careworn, at all times ready for one more metaphorical shoe to drop. When you’re locked in a dorsal state, chances are you’ll end up in a perpetual malaise, unable to meaningfully interact with the individuals in your life the world round you.
Fortunately, there’s a available technique to transfer your self up the polyvagal ladder to incorporate the protected and social emotions of the ventral state, and it begins together with your breath. “The best vagal stimulation you can recruit is with the ability to exhale slowly,” says Dr. Stephen Porges. Stimulating the vagus nerve with gradual exhales slows down the center price and provides your physique cues of security. “Within the mind stem there’s really form of like a change,” continues Porges. “It’s like a sizzling water/chilly water possibility on the identical knob. If you exhale, the vagal influences to your coronary heart’s pacemaker get optimized. If you inhale, your coronary heart price goes up. And while you exhale, your coronary heart price goes down. When you spend extra of your time exhaling, you calm your physique down. When you shift rations in order that more often than not you’re inhaling, you’re hyperventilating. You’re huffing and puffing. If you see anxious individuals, they’re inhaling on nearly each sentence or each phrase. They’re huffing and puffing.”
Tune Up Health founder Jill Miller designed a complete immersion program, Breath & Bliss, across the polyvagal principle, utilizing breath work, place, motion, group, and a gentle, air-filled sponge ball to manually stimulate the vagus nerve, and provides college students instruments to maneuver out of a fight-or-flight or shutdown state. “I need individuals to really feel like they’ve as many choices as potential to have the ability to modulate their very own state,” says Miller. “And to know the ‘why’ actually helps with the expertise of it. My bias is that I imagine as soon as you realize you can shift your physiology and also you practice your self to witness your physiological shifts, it turns into a richer expertise and also you don’t really feel so victimized by your moods or response to issues. I need empowered restoration to be in everybody’s toolkit.”
Breath & Bliss is a motion and breath-based method that leans into Porges’s principle of how we reply to our surroundings, and makes use of that data for steerage on getting ourselves to a state the place we are able to really feel protected with ourselves and within the firm of others. “One attribute of being a human being is that our physique reacts to menace,” says Porges. “However it doesn’t simply react to menace, it transforms how we work together with different individuals. So we’ve to know that our physique is shifting states to attempt to take excellent care of us, however in doing that, it distorts how we see the world. We all know that our our bodies change states and promote sure attributes to guard us. The difficulty is, can we create the construction and context for our our bodies to really feel welcoming sufficient to carry different individuals into our world? Can we surrender our continual should be defensive, to take an opportunity to be accessible and reside with our personal vulnerability?”
Senior Tune Up Health® Teacher Lisa Hebert leads the Breath & Bliss Immersion internationally and has seen it rework college students as they discover ways to transfer between states. “I believe the great thing about the polyvagal principle is that it brings us again to fundamentals,” says Hebert. “Social interplay, human contact, human connection, a caring voice. All of these items we all know so innately when we’ve a child in our arms, however we develop up and push all that away so we are able to get robust and do every thing ourselves. So we could lose it quickly, but it surely’s this innate data that we’ve in our intestine someplace.”
Hebert has additionally performed Breath & Bliss work with first responders and former navy members with PTSD. Jason Burd was a firefighter in Canada who nearly died when a roof collapsed in throughout a rescue operation in 2006. After the accident he went again to work, however suffered a again damage in 2010, adopted by a lung damage in 2011. He ended his profession as a firefighter due to bodily ache, PTSD, and suicidal ideas. He did Breath & Bliss with Hebert, the place he realized respiratory workouts and rolling strategies to stimulate the vagus nerve with the Coregeous ball. “There have been so many lightbulb moments,” says Hurd. “I spotted that my restoration is in my palms. Once I got here dwelling after the primary day of the course I instructed my spouse that I felt like the within of my neck was larger. My capability to breathe felt fully totally different. Now I exploit the Coregeous ball a minimal of as soon as a day, often twice.”
Hurd’s expertise is an instance of how tuning in to breath, and manually stimulating your personal vagus nerve, may end up in a strong shift from continual ache and fight-or-flight nervousness, to empowered restoration.
“That’s what I name embodiment,” says Miller. “It’s when somebody feels their approach by their physique, participating in a aware dialogue of their senses, emotions, urges, and wishes. Be prepared to reply and mother or father your self with curiosity and help.”
In keeping with Dr. Porges, understanding polyvagal principle might help us negotiate with our our bodies to optimize our experiences. “Amazingly, while you change into extra conscious of what your physique’s making an attempt to do, the physique tries to work with you. We’ve handled our physique as if it was one thing that we needed to comprise or management. However the message is that we reside in our physique. Deal with your physique with honor and respect, and your physique will serve you properly.”
Of all the excellent news science is telling us concerning the vagus, maybe crucial is that we’ve the power to befriend this wandering nerve proper this very minute. Whereas researchers everywhere in the world proceed to discover methods trendy medication can use the vagus nerve to heal continual illness, you can begin respiratory now. You can begin listening to the cues your physique is providing you with now. You possibly can start taking your restoration into your personal palms now.

At-A-Look: Find out how to Stimulate Your Vagus Nerve to Flip ON Your OFF Swap
To assist your physique “activate” the vagus to enhance its operate, there are a number of social, physiological and bodily “tips” that your physique can make use of.
- The best technique to stimulate the vagus nerve is thru gradual, deep, diaphragmatic respiratory that emphasizes elongation of exhales.
- Singing, buzzing, or enjoying a wind instrument additionally excite this downregulation nerve. (As demonstrated beneath.)
- Massaging areas of the physique that are innervated by the vagus alters vagal tone and supplies a leisure response. These embody tolerable strain to:
- Muscle groups of face, aspect and entrance of neck and head
- Positioning the physique in ways in which compress and decompress areas the place the vagus nerve innervates:
- Rocking, which gently oscillates the top
- Neck stretches
- Stomach and torso rotations that compress and decompress the viscera
- Gently flexing and lengthening the backbone to have an effect on strain and/or stretch within the visceral space
- Chewing meals, sucking on meals/objects and gargling
- Safely rubbing the within of your ear (the bowl formed bits, not your ear canal)
- Constructive social interactions
- “Feeling protected within the arms of one other” or “Feeling protected within the arms of one other applicable mammal, like a canine,” Dr. Stephen Porges
- Meditation and Yoga
