Polyvagal Theory and Substance Use Disorder

Polyvagal theory (without the jargon): why your nervous system matters in addiction

Polyvagal Theory is basically a plain-language way to talk about something you’ve probably felt a hundred times: your body has different “modes,” and you don’t choose them with willpower.

When your nervous system senses safety, you tend to feel more like yourself. You can think clearly, reach out, problem-solve, and ride out hard feelings without needing to escape them.

When your nervous system senses danger, your body shifts into survival. That can look like anxiety, irritability, impulsivity, sleeplessness, and intense cravings.

And when your system senses overwhelm, it can flip into a kind of shutdown. That can feel like numbness, disconnection, hopelessness, or “I can’t do this.”

Polyvagal Theory, originally developed by Stephen Porges, and brought into everyday clinical work by people like Deb Dana, helps explain how those shifts happen in the autonomic nervous system and why they matter so much in substance use disorder (SUD).

This is one of the most important takeaways we share with clients:

It’s not “just willpower.”

For many people, substance use becomes a fast (temporary) way to regulate a dysregulated nervous system:

• To numb or quiet pain
• To energize out of collapse
• To calm panic, agitation, or insomnia
• To feel safe for a moment, even if the relief doesn’t last

To be really clear: “polyvagal theory treatment” isn’t a standalone cure, and it’s not a replacement for evidence-based addiction care. It’s a lens we use to guide treatment at River Rock Treatment. Our approach helps us get more precise about stabilization, emotional regulation, the “window of tolerance,” building safer connections, and reducing the need to rely on substances for nervous system relief.

The three nervous system states that show up in substance use disorder

Here’s a simple map.

Your autonomic nervous system (ANS) runs a lot of your “automatic” body functions, including stress responses. Two major branches matter here:

• Sympathetic nervous system: mobilization (your body gets you ready to act)
• Parasympathetic nervous system: rest and restore (your body slows things down)

The vagus nerve is a major pathway in this system. In polyvagal terms, we talk about two parasympathetic “flavors,” which is where the three common states come from.

Ventral vagal state: “safe and connected”

This is the state most people are aiming for in recovery, not because life is perfect, but because you have more options here.

Common signs:

• You feel more present in your body
• You can make eye contact, talk, and connect
• You have curiosity and flexible thinking
• You can tolerate discomfort without immediately reacting
• You can ask for help without it feeling humiliating or dangerous

How it supports recovery behaviors:

• Going to groups, showing up to sessions
• Calling someone before you use
• Eating, sleeping, and taking medications more consistently
• Noticing an urge and riding it out
• Making a repair after conflict instead of burning the whole thing down

Sympathetic activation: “fight or flight”

This is the revved-up survival mode.

Common signs:

• Anxiety, panic, dread
• Anger, irritability, arguments that escalate fast
• Restlessness, racing thoughts
• Hypervigilance (always scanning for what’s about to go wrong)
• Trouble sleeping (tired but wired)

How it connects to substance use:

• Some substances are used to downshift the intensity (often alcohol, opioids, benzos, cannabis)
• Some substances are used to match the energy or feel powerful, focused, or “on” (often stimulants)

Even when someone knows the consequences, sympathetic activation can make the urge feel like an emergency: Do something now.

If you or someone you know is struggling with these issues related to substance use disorder and needs support in navigating these challenging states of the nervous system, don’t hesitate to reach out for professional help. You can start this journey towards recovery by contacting River Rock Treatment.

Dorsal vagal state: “shutdown”

This is the “too much” state. It’s not laziness. It’s a protective collapse response.

Common signs:

• Numbness, fog, dissociation
• Feeling heavy, stuck, slowed down
• Hopelessness, “what’s the point?”
• Pulling away from people
• Not caring about things you usually care about

How it connects to substance use:

• Using to feel something when everything is flat
• Using to escape or stay detached
• Using because “being here” feels unbearable

A practical way we talk about this is: state drives story.

When your state shifts, your thoughts shift. Your beliefs shift. Your sense of risk shifts. Your ability to choose shifts. That’s a big reason relapse can happen under stress, even when someone truly wants recovery.

How trauma and chronic stress push the system out of balance

Trauma and chronic stress train the nervous system to become very good at one job: detecting threat.

After you’ve been hurt, abandoned, overwhelmed, or trapped, your body can start reacting to small cues as if they’re big dangers. A tone of voice, a text message, a look, a smell, a time of year, a slammed cabinet door. The thinking brain might say, “This is fine,” while the body says, “Nope. Not safe.”

Polyvagal theory uses the term neuroception, which is a fancy word for something simple:

Your nervous system has an automatic safety scanner, and it works without asking your permission.

After trauma, that scanner can become overprotective. It can misread neutral situations as dangerous, which can kick off sympathetic activation or dorsal shutdown fast.

This matters in addiction because substances can “borrow” a wider window of tolerance temporarily. They can create:

• Relief from panic
• Distance from emotional pain
• A sense of energy or confidence
• A feeling of belonging or safety (even if it’s short-lived)

The problem is the rebound. When the substance wears off, many people feel more dysregulated:

• More anxiety
• Worse sleep
• More irritability
• More depression or flatness
• More shame (which is its own nervous system trigger)

We also commonly see co-occurring mental health conditions like anxiety and depression, and nervous system dysregulation can mimic them, worsen them, or keep them stuck.

Polyvagal theory is also discussed in relation to physical health patterns (you’ll hear people mention inflammation and other body systems), but our focus here is more practical: stabilizing SUD and mental health symptoms so recovery is actually livable.

What “polyvagal-informed” addiction treatment looks like in real therapy sessions

When we say “polyvagal-informed,” we mean we’re paying attention to what’s happening in your body and nervous system, not just what you’re thinking.

In real sessions, that often looks like:

• Tracking state shifts (What happens in your body when you get triggered?)
• Identifying cues of danger (What reliably throws you into panic, rage, or shutdown?)
• Practicing skills that support a shift toward ventral vagal regulation (What helps you come back online without using?)
• Building relapse prevention plans that include your nervous system, not just your intentions

Co-regulation: healing in connection

One of the most underrated parts of recovery is safe connection.

Polyvagal theory highlights the social engagement system: our bodies regulate better when we feel seen, heard, and safe with someone. That’s not a weakness. That’s biology.

So co-regulation might look like:

• A therapist helping you slow down and notice what’s happening
• A group where your experience gets normalized instead of judged
• Practicing asking for support before things hit a breaking point

Pacing: stabilization before deep trauma work

A huge part of polyvagal-informed care is pacing.

If we push too fast into trauma processing, some people will spike into sympathetic activation (panic, impulsivity, craving) or drop into dorsal shutdown (numb, detached, “I’m fine,” then disappear).

So we prioritize stabilization first:

• building skills
• increasing the window of tolerance
• strengthening support
• improving sleep and daily rhythm
• reducing immediate relapse risk

How does it fit into outpatient care

In outpatient work, the loop is simple and powerful:

We practice skills in session, then you practice them in real life, then we review what happened and adjust.

Over time, goals often include:

• better distress tolerance
• fewer blow-ups and less shutting down
• improved sleep regulation
• less reactivity in relationships
• more ability to pause between urge and action

Polyvagal exercises we commonly use (and why they work)

These aren’t magic tricks. They are ways to give your nervous system a different option besides “white-knuckle it” or “use.”

Breathwork for downshifting (simple, not intense)

A gentle starting point is breathing that emphasizes a longer exhale.

Why it helps: A slower exhale is one of the clearest “we’re okay” signals you can send your body.

Try this:

• Inhale through the nose for 4
• Exhale slowly for 6 to 8
• Repeat for 2 to 5 minutes

Keep it low pressure. If focusing on breath makes you anxious, we adjust. There are plenty of other routes to regulation.

Box breathing vs. longer-exhale breathing

Both can help, but they’re useful in different moments.

Box breathing (ex: 4 in, hold 4, out 4, hold 4) can be helpful when you feel scattered and need structure. Some people love it for cravings and spiraling thoughts.

Longer-exhale breathing (ex: 4 in, 6 to 8 out) is often better for sympathetic activation and physical anxiety.

If you’re in dorsal shutdown (numb, foggy, collapsed), heavy “calming” breathwork can sometimes make you feel more shut down. In that state, we often start with gentle mobilization first.

Movement for mobilization (discharging survival energy safely)

When the body is in fight or flight, it often needs a safe way to complete that stress cycle. Emily and Amelia Nagoski discuss such methods extensively.

A few options:

• a short walk outside
• light stretching
• shaking out hands and legs for 30 to 60 seconds
• pushing against a wall, then releasing
• a quick set of stairs if it’s safe for your body

The point is not fitness. The point is giving your body a way to move through the activation without substances.

A safety plan for shutdown (micro-actions, not “push through it”)

Shutdown is where people often get stuck because the usual advice is useless: “Just try harder.”

Instead, we use micro-actions:

• sip water
• change temperature (cold water on wrists, warm tea, step outside for air)
• sit up, then stand up (even if you sit back down)
• open a window, turn on a light
• send a one-line text to a safe person: “I’m not doing great. Can you check in?”

The goal is to create a little bit of movement toward connection and aliveness, not to force yourself into motivation.

Personalization matters

Regulation isn’t about being calm all the time.

The real goal is more choice:

• noticing your state sooner
• having a couple of tools that reliably help
• staying connected to your values even when you’re activated
• reducing the urgency of cravings

Vagal tone, heart rate variability, and what “regulation” can (and can’t) be measured by

You might hear people talk about vagal tone as if it’s a score you should improve.

In everyday terms, vagal tone is basically: how easily your system can return to safety after stress.

Some people track heart rate variability (HRV) with a wearable as a rough proxy. That can be interesting and sometimes helpful, but we don’t want to overhype it.

A few reality checks:

• HRV is influenced by sleep, illness, hydration, overtraining, caffeine, meds, and more
• A number can’t tell you the full story of trauma, recovery, or safety
• Watching metrics too closely can become its own anxiety spiral

What matters clinically is more functional and more humane:

• Are you sleeping better?
• Are cravings less intense or shorter?
• Are you recovering from stress faster?
• Are relationships feeling more stable?
• Are you showing up for your life more consistently?

If tracking helps, we often suggest a simple “state check-in” journal:

• What happened (trigger)?
• What did I notice in my body (tight chest, buzzing, numbness)?
• What state do I think I was in (activated, shutdown, connected)?
• What helped, even 5%?

Wearable data can be optional, as long as it’s not fueling compulsiveness. We prioritize function over perfect numbers.

How polyvagal theory fits with evidence-based addiction therapies (CBT, EMDR, and more)

Polyvagal-informed work is not an alternative to evidence-based treatment. It’s more like the missing “body piece” that helps other therapies work better.

CBT + polyvagal

CBT skills are harder to use when you’re outside your window of tolerance.

If your nervous system is in threat mode, “challenge the thought” can feel impossible. So we often go body-first:

1. notice activation or shutdown
2. use a regulation skill to come closer to center
3. then work with thoughts, beliefs, and choices

It’s not either-or. It’s sequencing.

EMDR + polyvagal

EMDR can be very effective for trauma, and polyvagal-informed pacing matters here.

We focus on:

• stabilization
• resourcing
• readiness
• titration (not flooding the system)

In other words, trauma processing goes better when your nervous system has enough safety, support, and flexibility to handle it.

Motivational work (and the role of shame)

When someone is in a threat state, shame often gets louder:

• “I’m broken.”
• “I always mess up.”
• “They’ll judge me.”

Those are not “just thoughts.” They often show up with a body state.

As safety and connection increase, people usually have more access to honest change-talk:

• “I want something different.”
• “I’m scared, but I’m willing.”
• “I can take one next step.”

Group therapy as nervous system medicine

Groups can be powerful because they offer:

• normalization of state shifts
• co-regulation
• practice being seen without being punished
• a relapse-protective sense of belonging

Medication and psychiatry (when appropriate)

Medication can support stabilization for some people, especially with anxiety, depression, sleep, or cravings. Skills still matter for long-term nervous system flexibility, and any medication decisions should be made with a qualified prescriber who knows your history.

Polyvagal theory and common co-occurring conditions we see in recovery

Anxiety

A lot of anxiety maps onto sympathetic activation.

We work on:

• spotting early cues (jaw clench, racing thoughts, tight chest, doom scrolling)
• downshifting without avoidance
• building tolerance for normal stress so everything doesn’t feel like an emergency

The goal isn’t zero anxiety. It’s “I can handle this without blowing up my life.”

Depression vs. shutdown

Depression is real and complex, and sometimes what looks like depression is heavily influenced by dorsal vagal shutdown.

A practical distinction we sometimes explore:

• Sadness can still have connection, tears, meaning, and movement.
• Collapse often feels numb, frozen, empty, “I can’t.”

When shutdown is prominent, we often use gentle mobilization plus connection:

• small routines
• brief sunlight exposure
• one safe contact
• tiny tasks that build momentum

Sleep disruption

Sleep is one of the first places nervous system states show up.

• Sympathetic insomnia: tired but wired, racing mind, body on alert
• Shutdown fatigue: sleeping a lot but not feeling restored, heavy mornings, low motivation

We often build evening routines that cue safety:

• lower lights
• consistent wind-down time
• gentle breath or stretching
• device boundaries (even small ones)
• a predictable “close the day” ritual so your body stops scanning

Chronic health considerations

You’ll hear growing interest in how stress physiology relates to physical health conditions (including inflammatory disorders and other areas). We’re not making medical claims here, and we always encourage medical guidance for medical concerns. From a recovery standpoint, reducing chronic stress and improving regulation often supports overall functioning.

Integrated care matters

When we treat SUD and mental health together, relapse risk usually goes down. Stabilization is easier to maintain when you’re not fighting your brain and body on multiple fronts alone.

Criticisms and challenges: what polyvagal theory gets right, and where people debate it

It’s worth saying out loud: polyvagal theory has criticisms and challenges, especially in academic circles. Some debates include whether certain parts are oversimplified or whether specific biological claims have strong enough evidence.

Our stance is practical.

We use polyvagal theory as a framework for noticing nervous system states and building emotional regulation and connection. We don’t use it as a rigid “this is the one true explanation for everything.”

What’s broadly well-supported, regardless of theoretical debates:

• the autonomic nervous system drives stress responses
• trauma impacts physiology
• chronic stress narrows the window of tolerance
• safe connection and supportive relationships help people heal

If the skills help you reduce cravings, improve relationships, and build stability, that’s meaningful, even if the academic conversation continues to evolve.

Training and resources (if you want to go deeper)

If you want reputable places to learn more, here are a few we trust:

• Polyvagal Institute (education and training rooted in polyvagal theory)
• National Institute for the Clinical Application of Behavioral Medicine (NICABM) (clinician-friendly trauma and nervous system education)
• Deb Dana’s work (books and worksheets that are especially approachable)

A simple starting plan we often recommend:

1. Learn your top cues of safety and danger (in your body and environment).
2. Pick two regulation practices you can actually stick with.
3. Practice daily for two weeks (keep it small and realistic).
4. Review what changed: cravings, sleep, reactivity, relationships, follow-through.

Learning helps, but change usually happens with supported practice, especially when substance use disorder and trauma are part of the picture.

FAQs (Frequently Asked Questions)

What is Polyvagal Theory, and how does it relate to addiction?

Polyvagal Theory explains how your nervous system shifts between different states—safety, danger, and overwhelm—and how these shifts affect behavior. In addiction, understanding these states helps explain why substance use often serves as a way to regulate a dysregulated nervous system by numbing pain, calming panic, or energizing out of collapse.

What are the three nervous system states described in Polyvagal Theory relevant to substance use disorder?

The three states are: 1) Ventral vagal state (‘safe and connected’), where you feel present and can connect with others; 2) Sympathetic activation (‘fight or flight’), characterized by anxiety, irritability, and hypervigilance; and 3) Dorsal vagal state (‘shutdown’), marked by numbness, disconnection, and hopelessness. Each state influences substance use behaviors differently.

How does the ventral vagal state support recovery from substance use disorder?

In the ventral vagal state, individuals feel safe and connected, which allows for curiosity, flexible thinking, and emotional regulation. This state supports recovery behaviors such as attending therapy groups, managing urges without acting on them, maintaining routines like eating and sleeping well, and repairing relationships after conflicts.

Why is substance use often mistaken as a matter of willpower according to Polyvagal Theory?

Polyvagal Theory highlights that nervous system states drive behavior automatically. Substance use often serves as a coping mechanism to regulate overwhelming or dysregulated nervous system states rather than simply a failure of willpower. Recognizing this shifts the focus toward addressing underlying nervous system needs in treatment.

Can Polyvagal Theory be used as a standalone treatment for addiction?

No, Polyvagal Theory is not a standalone cure for addiction. It is a lens or framework used alongside evidence-based addiction care to better understand nervous system regulation. This approach helps guide treatment strategies focused on stabilization, emotional regulation, building safer connections, and reducing reliance on substances for relief.

How do sympathetic activation and dorsal vagal shutdown influence substance use behaviors?

Sympathetic activation (fight or flight) can lead to urgent urges to use substances either to calm intense feelings (downshift) or match high energy (upshift). Dorsal vagal shutdown (overwhelm) can drive substance use to feel something when numb or to escape unbearable feelings. Understanding these patterns helps tailor interventions to support recovery.
