Healing Through the Vagus Nerve

1. The Nervous System is the Foundation of All Healing

I believe that nervous system regulation is the foundation to all other healing, not just because I witness it every day with clients, but because of my own personal healing journey as well.

Beyond the mind. Many people mistakenly believe anxiety, depression, stress, and trauma are "all in their head." However, these experiences are deeply rooted in the body, making nervous system regulation the crucial first step for profound and lasting healing. Understanding how your body's communication network functions empowers you to work with it, rather than constantly fighting against your own mind and body.

The Autonomic Nervous System (ANS). This involuntary system governs vital functions like heartbeat, breathing, and digestion, and significantly impacts mental health. It operates like a seesaw between two states:

• Parasympathetic (Rest & Digest / Green Zone): A relaxed state where the body functions optimally, promoting calm, connection, and safety.
• Sympathetic (Fight or Flight / Yellow Zone): An activated stress response, mobilizing the body for action, leading to worry, anger, or panic.
  Ideally, we spend most of our time in the parasympathetic state, only temporarily shifting to sympathetic activation.

Dysregulation's impact. When the ANS is chronically stressed or overwhelmed, it becomes dysregulated, leading to a cascade of seemingly unrelated symptoms. These can range from chronic pain, digestive issues, and low immunity to anxiety, depression, and difficulty concentrating. By addressing the root cause—nervous system dysregulation—many of these symptoms can begin to subside, unlocking the body's natural capacity to heal.

2. The Vagus Nerve: Your Mind-Body Superhighway

The vagus nerve is your mind-body superhighway, sending nonstop information from body to brain and brain to body.

The wandering nerve. Named for its "wandering" path, the vagus nerve is the longest cranial nerve, extending from the brainstem to the colon, connecting to major organs like the heart, lungs, and gut. It constitutes 75-80% of your parasympathetic nervous system, making it central to dampening the fight-or-flight response and fostering relaxation.

Bidirectional communication. Crucially, 80% of the vagus nerve's signals are afferent—sending information from the body to the brain. Only 20% are efferent, from brain to body. This highlights why "bottom-up," body-based practices are so effective for healing chronic stress, anxiety, and trauma, as our physiology profoundly impacts our psychology.

Vast functions. The vagus nerve's intricate branches regulate a multitude of bodily processes:

• Head & Neck: Influences eye contact, facial expressions, speech, gag reflex (via auricular and pharyngeal branches).
• Thorax: Regulates airflow in lungs, heart rate, and blood pressure.
• Abdomen: Optimizes digestion, nutrient absorption, blood sugar balance, and modulates inflammation (via connections to stomach, liver, pancreas, spleen, intestines).
  Improving vagal health is a powerful way to rebalance the nervous system and mitigate the negative effects of chronic stress.

3. Dysregulation is a Logical Response, Not a Flaw

What I hope you come to see is that oftentimes this activation or shutdown of your system may actually be a healthy response to an unhealthy circumstance—a healthy and protective response to what you’ve been through or are currently experiencing.

Survival mode. Your nervous system's primary job is survival. When faced with perceived threats—whether from past trauma or current stressors—it activates protective responses. Anxiety (sympathetic activation/yellow zone) is your system mobilizing to "fight or flee," while depression (dorsal vagal shutdown/red zone) is your system immobilizing to "freeze" or conserve energy when overwhelmed. These are not signs of brokenness, but adaptive, protective mechanisms.

The "stress bucket" analogy. Imagine your nervous system as a bucket. Daily stressors—work, relationships, finances, poor sleep, trauma—fill this bucket. When the load becomes too heavy, your system gets pushed down the "autonomic nervous system ladder" into activation or shutdown. The goal isn't to eliminate stress, but to manage the load by increasing your capacity or decreasing the weight in the bucket.

"Of course" framework. This powerful reframe shifts perspective from "something is wrong with me" to "of course this makes sense." Your current nervous system state is a logical outcome of:

• Past lived experience: Childhood trauma, unmet needs, learned coping.
• Current life circumstances: Ongoing stressors, environment.
• Coping skills/resourcing: The tools you currently possess (or lack).
  Understanding this equation fosters self-compassion and curiosity, paving the way for intentional change rather than self-judgment.

4. Personalize Your Nervous System Map for Deeper Awareness

The greater the awareness, the greater your potential to reconnect to your body, rewire your mind, and reclaim your life.

Cultivating interoception. Interoception is your "sixth sense"—the ability to perceive and understand internal body signals like hunger, thirst, or subtle shifts in emotional states. It's vital for self-awareness and self-regulation. By intentionally tuning into sensations, you gain crucial feedback about your physiological and emotional needs, empowering you to take appropriate action.

Mapping your unique states. While nervous system states have universal characteristics, your personal experience of them is unique. Creating a "nervous system map" involves identifying your specific:

• Sensations: What does activation feel like in your body (e.g., tight chest, racing heart)? What about shutdown (e.g., numbness, heaviness)?
• Emotions: What feelings accompany each state (e.g., anger, panic, apathy, hopelessness)?
• Thoughts: What narratives or beliefs emerge (e.g., "I must do this now," "What's the point?")?
• Behaviors: What actions do you take or avoid (e.g., overworking, isolating, fidgeting)?
  This detailed map helps you recognize shifts earlier and choose the right tools.

Your baseline state. Understanding your default nervous system state—whether you tend to be more activated, shut down, or regulated—is key. This awareness informs which regulation tools will be most effective for you. For instance, if you're chronically activated, you'll need different strategies than if you're often in shutdown. This personalized insight moves you from feeling helpless to empowered, knowing why you feel a certain way and what you can do about it.

5. Vagal Tone is Adaptable and Measurable

The most important thing to know is that vagal tone is adaptable and, regardless of where you are right now, it can improve and have a profound impact on your mental and physical health.

Understanding vagal tone. Vagal tone measures the activity and function of your vagus nerve.

• High vagal tone: Indicates an active, properly functioning vagus nerve, promoting balance, resilience to stress, better emotional regulation, stable energy, good digestion, and improved mental/physical health.
• Low vagal tone: Suggests inefficient vagus nerve function, contributing to poor stress management, increased reactivity, hormone imbalances, digestive issues, anxiety, and depression.
  Crucially, vagal tone is not fixed; it's adaptable and can be significantly improved through consistent effort.

Causes of low vagal tone. Various factors can diminish vagal tone:

• Chronic stress & trauma: Prolonged sympathetic activation inhibits the vagus nerve.
• Childhood experiences: Adverse experiences or maternal stress during pregnancy can impact development.
• Chronic inflammation: Consistent low-grade inflammation is linked to reduced vagal activity.
• Medical conditions/injury: Diabetes, infections, or physical trauma can affect the nerve.
• Lifestyle factors: Poor sleep, sedentary habits, inflammatory diet, bad posture, and certain substances (e.g., alcohol, antibiotics).

Assessing your vagal tone. While no single test directly measures vagal tone, several methods provide insight:

• Heart Rate Variability (HRV): The most accurate objective measure, tracking variations in time between heartbeats. Higher HRV indicates better vagal tone.
• Symptom clusters: Identifying patterns of gastrointestinal issues, sleep problems, chronic pain, anxiety, or depression.
• Manual observations: Observing breathing patterns (mouth vs. nasal, shallow vs. deep), or a pharyngeal vagus branch test.
• Device-assisted metrics: Wearable devices can track HRV, breath rate, and sleep quality.
  The goal is to track your changes over time, not compare to others, to see the positive impact of your efforts.

6. Healing Follows a Strategic Four-Phase Journey

Healing is never perfectly linear, but if your journey has felt overwhelming or ineffective at times, it’s likely happening out of order.

A structured approach. Healing can feel overwhelming without a clear roadmap. This four-phase framework provides a strategic, neuroscience- and trauma-informed path that supports your mind-body system, rather than stressing it further:

1. Education and Awareness: Understanding how your nervous system and vagus nerve work, and how they uniquely manifest in your body. (This book's initial chapters).
2. Regulation: Learning to identify dysregulation and implementing proactive and reactive tools to feel more grounded and stable. This builds capacity for deeper work.
3. Rewiring: Engaging in deeper healing modalities like talk therapy, meditation, or parts work, after a foundation of regulation is established. Attempting this too soon can be dysregulating.
4. Resourcing: Maintaining your new baseline with ongoing supportive practices, recognizing that life's ebbs and flows may require cycling back through earlier phases.

Repetition over time. Improving vagal tone and rewiring your nervous system is a gradual process, akin to building muscle. It requires "regulating repetitions" accumulated consistently over time.

• Consistency is key: Small, consistent actions are more impactful than sporadic, intense efforts.
• Nervous system plasticity: Your system is constantly adapting; you can regulate what has been dysregulated.
• Patience: Healing takes time; ditching urgency and celebrating small wins is crucial.

Avoiding pitfalls. Healing can be slowed by:

• Overwhelm: Trying to do too much too soon, which adds stress.
• Toxic environments: Constant stressors can negate healing efforts.
• Skipping phases: Jumping into deep trauma work without a regulatory foundation can exacerbate symptoms.
  Strategic, gradual, and consistent effort is the most effective path to lasting change.

7. Proactive Habits Build Lasting Vagal Tone

Proactive practices include consistent habits and lifestyle routines to improve vagal tone and create a life more suited for nervous system regulation.

Building resilience. Proactive healing involves integrating consistent habits and lifestyle choices that enhance vagal tone and foster a regulated nervous system. These practices decrease the likelihood of dysregulation and build your capacity to handle life's stressors. The goal is not an overnight overhaul, but small, sustainable shifts.

Nine key proactive categories:

• Sleep: Aim for 8 hours of quality sleep with consistent timing; it's the most fundamental habit.
• Movement: 150+ minutes of heart-pumping activity weekly, or even a daily walk, positively impacts the vagus nerve.
• Breath: Practice slow, deep, diaphragmatic nasal breathing to stimulate the vagus nerve.
• Vagal Toning Practices: Specific exercises (like gargling, humming) to directly activate the vagus nerve.
• Gut Health: A diverse, whole-food diet, probiotics, and stress management support the gut-vagus nerve connection.
• Vision Therapy: Balancing close-up screen time with distance viewing and specific eye exercises can shift stress responses.
• Community: High-quality social interactions activate the vagus nerve, offering protection against trauma and mental health issues.
• Repatterning: Deeper work (mindset, trauma healing) to reduce hypervigilance and improve emotional regulation, ideally with professional support.
• Environment & Stress Management: Minimize exposure to toxic environments and manage overall stress load.

Start small, optimize. To make these changes stick, identify your number one self-care habit and the easiest practice to incorporate. Start with a "laughably small" step—something you can commit to even on your worst days. For example, instead of a 30-minute meditation, start with three deep breaths upon waking. Layer new habits gradually, attaching them to existing routines, and celebrate every small win.

8. Reactive Tools Offer Immediate Regulation

Reactive practices are the in-the-moment regulation exercises that help you reverse the spiral of activation or shutdown.

In-the-moment support. Reactive healing tools are designed to help you push back against your body's stress response in real time, activating your vagus nerve and regulating your nervous system. These are essential for managing acute moments of anxiety, panic, or feeling shut down. They should also be practiced proactively in smaller moments of stress to build familiarity and accessibility for bigger challenges.

Regulating from activation (fight-or-flight). When highly activated, your system is primed for movement. Trying to force stillness can be counterproductive. Instead:

• Meet motion with motion: Start with gentle swaying, stretching, heel drops, or somatic shaking to discharge excess energy.
• Engage senses: Hold an ice cube, suck on sour candy, or go for a walk to jolt the system.
• Breathwork: Extended exhale breath or box breathing can gradually calm the system.
• Vision exercises: Orienting, gaze opening, or eye cupping can shift focus and reduce tunnel vision.
  The goal is to move even one small step towards feeling more settled, less urgent, and breathing more deeply.

Regulating from shutdown (freeze/depression). These states conserve energy and prevent pain through immobilization and disconnection. Regulation involves gently inviting connection and mobilization:

• Gentle connection: Intentional rest, single task actions (e.g., moving from bed to couch), listening to music, or gentle body squeezes.
• Sensory engagement: Experience temperature changes (cold water on hands, cold shower), or sensory awareness (5-4-3-2-1 technique).
• Subtle mobilization: Somatic posture changes (from collapsed to open), or sharp breathing to invite gentle activation.
  Remember, the shift from shutdown often involves passing through a phase of activation; be prepared to use tools from both categories.

9. Build Your Routine with Tiny, Layered Habits

Changing your life means changing something you do daily. Healing lies in your daily routine.

The power of consistency. Sustainable habit change prioritizes "what you can still stick to even on your worst days" over an "ideal" routine. Start with tiny, seemingly insignificant practices, and layer them gradually. Each small, consistent action stimulates your vagus nerve and contributes to improved vagal tone without adding stress.

Establishing your routine. Begin by identifying:

• Your #1 self-care habit: What single habit, when consistently done, makes the biggest difference in your overall well-being? (Often sleep).
• The easiest practice: Which vagal toning exercise from Chapter 6 feels most accessible to incorporate right now?
  Then, make a "laughably small" change. For example, if sleep is your #1, and you scroll before bed, start by plugging your phone in across the room.

Routine blueprint example (Phase 1):

• A.M.: 30 seconds of gargling (after brushing teeth).
• P.M.: 30 seconds of gargling + 1-5 minutes of intentional diaphragmatic breathing (before sleep).
  This simple start builds awareness and vagal activation. Subsequent phases gradually add more practices like morning sunlight, "voo" breaths, legs up the wall, eye stretches, movement, and massage, often by layering them onto existing habits (e.g., "voo" breaths while getting morning sun).

Flexibility over perfection. Your routine will evolve with your capacity and life's seasons. Ditch rigid perfectionism; "something is better than nothing." On rushed days, scale back to just one practice. The combination of proactive routines and reactive tools creates a powerful, personalized healing protocol that fits your unique life.

10. Embrace Compassion, Curiosity, and Co-regulation

The key is to lean into the truth that in any given moment you’re doing the best you can based on the current state of your nervous system, past lived experiences, and the tools that you have.

Self-compassion is key. Understanding your nervous system fosters deep compassion for yourself. When you overreact or feel overwhelmed, instead of self-judgment ("I'm a bad mom," "I'm too dramatic"), you can recognize these as signs of dysregulation. This shift in narrative allows you to acknowledge your feelings and turn to your regulation toolbox, rather than fueling shame.

Cultivate curiosity. Instead of reacting instinctively, pause and ask:

• "What's up? What's contributing to my dysregulation right now?"
• "What might have just been triggering?"
• "What would I like to do about it?"
  This curious inquiry puts you in the driver's seat, empowering you to respond intentionally rather than being swept away by automatic reactions. It transforms moments of struggle into opportunities for self-discovery and growth.

The power of co-regulation. Humans are hardwired for connection, and it's okay—and normal—to need support. Co-regulation, or regulating with another person, is vital for healing. Don't shy away from seeking professional help or leaning on supportive relationships. Healthy social connection activates your vagus nerve, increasing your parasympathetic response and sense of safety. Just as an athlete needs a coach, you may benefit from guidance on your healing journey.
