Stop Chasing Symptoms. Start Healing the Root.
Article By: Matt Spaid
There’s a powerful nerve running through your body that influences almost every major system—yet it’s often overlooked in traditional medicine and even functional health circles. It’s called the vagus nerve, and if it isn’t functioning properly, nothing else may fully heal.
I’ve been diving into the book “Accessing the Healing Power of the Vagus Nerve” by Stanley Rosenberg, and it’s opening up a whole new framework for understanding healing—especially for veterans, first responders, and tactical professionals dealing with chronic pain, PTSD, or what many of us know as Operator Syndrome.
What Is the Vagus Nerve?
The vagus nerve is the tenth cranial nerve and the main communication highway of the parasympathetic nervous system—the “rest and digest” system. It’s the longest cranial nerve in the body, running from the brainstem down through the face, neck, heart, lungs, and into the digestive organs.
It has two primary branches:
- The ventral vagus (linked to social engagement, calm, and healthy organ function)
- The dorsal vagus (associated with freeze response, dissociation, and visceral shutdown)
When this system is out of balance, it doesn’t just affect your stress—it can impact your breathing, digestion, heart rate, immune function, mental clarity, and more.
Case in Point: COPD and the Vagus Nerve
One example Rosenberg gives is COPD. Most people think COPD is just a lung problem, but what if it’s also a nerve regulation problem?
- The dorsal vagus constricts the bronchioles, reducing airflow.
- The sympathetic system opens them up for maximum oxygen intake (fight or flight).
- But in a healthy state, the ventral vagus should relax the bronchioles—allowing smooth, regulated airflow in and out of the lungs.
If the ventral branch isn’t working properly, no amount of medication will fix the root issue. You’re stuck chasing symptoms like the Hydra from Greek mythology—cutting off one head just to have another grow back.
Autonomic Dysfunction = Systemic Dysfunction
Many conditions—chronic fatigue, digestive problems, anxiety, depression, trauma response, even autoimmune issues—may stem from autonomic nervous system imbalance, especially vagus nerve dysfunction.
Think about it:
- If you’re constantly in sympathetic overdrive (fight or flight), your digestive enzymes shut down, immune function tanks, and breathing patterns become dysfunctional.
- If the dorsal vagus dominates, you may experience numbness, disconnection, poor circulation, low energy, and shutdown.
- If the ventral vagus is strong, you feel safe, grounded, clear-minded, and resilient.
A Simple Test for Vagal Function
Here’s one test from Rosenberg’s book:
- Have the person sit comfortably.
- Ask them to open their mouth and say: “Ah, ah, ah, ah” in short, percussive bursts.
- Observe the soft palate and arches on either side of the uvula.
- If both arches rise symmetrically, vagal tone is likely strong.
- If one side doesn’t lift, there may be a dysfunction in the ventral branch of the vagus.
This is just one simple diagnostic tool—yet it reveals a much deeper truth: if the communication system of the body is broken, healing becomes an uphill battle.
Why This Matters for Veterans and First Responders
Many of us in the tactical world have lived in fight-or-flight for years—or decades. The cost?
- Chronic gut issues
- Breathing disorders
- Numbness or emotional disconnection
- Chronic fatigue
- Difficulty healing from injury
- Difficulty finding peace
This is Operator Syndrome through the lens of polyvagal theory. Your nervous system may not be broken—it may just need to be retrained.
What Can You Do?
At Operation Antifragile, we use a combination of:
- HRV breathing (5-6 breaths/min)
- Euphoric breathwork and diaphragmatic training
- Cold exposure and vagal toning exercises
- Red light therapy and gut-brain nutrition
- Balance and vestibular work to activate cranial nerves
These tools are all part of how we train the vagus nerve—and help our tribe rebuild from the inside out.
Final Thought
If you’ve been chasing symptoms and spinning your wheels, maybe it’s time to zoom out. Maybe the real issue isn’t where you’re looking. Maybe it’s how your system is wired.
Strength starts with the nervous system.
Resilience starts with the breath.
And healing starts when we stop chasing and start listening.
