Polyvagal Theory in Therapy

A nervous-system-informed framework used selectively to support awareness, regulation, and relational safety within a wider treatment plan.

Polyvagal theory is a framework developed by Stephen Porges to explain how the autonomic nervous system may influence experiences of safety, connection, mobilization, and shutdown. Its language has become widely used in trauma therapy, somatic practice, education, and popular discussions of nervous-system regulation.

Some clients find this framework helpful because it gives understandable language to experiences that can otherwise feel confusing: becoming suddenly activated, withdrawing, feeling numb, losing access to speech, or finding it difficult to connect even when no immediate danger is present.

Polyvagal theory is not the same as established autonomic physiology, and several of its central anatomical and evolutionary claims remain scientifically contested. At THE BALANCE, selected polyvagal concepts may be used as clinical metaphors or psychoeducation when they help the individual. They are not presented as a diagnostic test, a complete explanation of trauma, or proof that one exercise has “reset” the nervous system.

Each fully private residential program is dedicated to one client. Regulation-focused work can therefore be adapted to psychiatric presentation, trauma history, dissociation, physical health, sensory preferences, cultural context, and response.

What Is Polyvagal Theory?

Polyvagal theory was introduced in the 1990s as an account of how the vagus nerve and broader autonomic nervous system relate to emotion, defensive behavior, social engagement, and adaptation to perceived threat.

The theory emphasizes that human responses are not determined only by deliberate thought. It uses the term neuroception for proposed detection of safety or danger outside conscious awareness. Heart rate, breathing, muscle tension, attention, voice, and social behavior can change rapidly in response to context.

The autonomic nervous system clearly participates in stress and regulation. Polyvagal theory adds a specific hierarchy and evolutionary interpretation to these processes; that interpretation is where much of the scientific debate lies.

The Autonomic Nervous System

The autonomic nervous system contributes to regulation of heart rate, blood pressure, breathing, digestion, temperature, pupil response, and other functions. It includes sympathetic and parasympathetic pathways that interact dynamically rather than operating as simple opposites.

The vagus is a major cranial nerve with sensory and motor pathways connecting the brain with structures in the neck, chest, and abdomen. It contributes to parasympathetic regulation, but neither emotional life nor trauma can be reduced to the vagus nerve alone.

A client may experience racing heart, shallow breathing, numbness, digestive changes, freezing, or social withdrawal for many reasons. Psychiatric symptoms, medication, sleep, substance use, pain, endocrine conditions, cardiovascular factors, neurological illness, and context may all be relevant. (source: WHO, 2024)

The Three-State Model

Polyvagal-informed practice often describes three broad patterns:

• Ventral vagal or socially engaged. A state associated in the theory with relative safety, connection, flexibility, facial expression, and communication.
• Sympathetic mobilization. A state associated with increased energy for action, including fight, flight, urgency, agitation, or anxiety.
• Dorsal vagal or immobilized. A state associated in the theory with conservation, withdrawal, numbness, collapse, or shutdown.

These descriptions may help a client notice patterns, but real autonomic activity is more complex. People can experience mixed states, and the same behavior can arise for different reasons. Quietness is not necessarily shutdown, increased energy is not necessarily danger, and social engagement does not prove physiological safety.

The three-state model should therefore be used as a flexible map rather than an objective classification system.

Co-Regulation and Relational Safety

Co-regulation describes the ways people may influence one another’s emotional and physiological states through voice, expression, proximity, rhythm, predictability, touch, and relationship.

The broader importance of supportive relationships is not unique to polyvagal theory. Therapeutic alliance, attachment, social support, and interpersonal regulation are well-established areas of psychological research.

In practice, the therapist may pay attention to pace, tone, permission, boundaries, distance, and whether the client feels able to say no. The aim is not to make the therapist responsible for controlling the client’s nervous system. It is to create conditions in which the client has greater choice and sufficient safety to engage in treatment.

How Polyvagal Concepts May Be Used in Therapy

Polyvagal-informed work usually consists of psychoeducation and regulation-focused practices incorporated into another therapeutic approach.

A session may involve:

• identifying changes in activation, energy, attention, and social connection;
• noticing cues associated with relative safety or threat;
• orienting visually or auditorily to the current environment;
• experimenting with posture, movement, or distance;
• using breathing only when it is comfortable and clinically appropriate;
• recognizing the sequence that occurs before panic, shutdown, anger, or substance use;
• developing more than one way to return to the present;
• examining how relationships affect regulation;
• connecting bodily awareness with psychotherapy and daily behavior.

The clinician should explain which parts are established therapeutic practice and which are being described through a polyvagal lens.

Regulation Is Not Permanent Calm

A regulated nervous system is not one that remains calm at all times. (source: PTSD clinical guidance)

Mobilization can be adaptive when a person needs energy, protection, focus, or assertiveness. Temporary withdrawal can provide recovery or reduce stimulation. The aim is greater flexibility: recognizing what is happening, responding proportionately, and returning from activation when the situation changes.

Therapy should not teach clients to interpret every increase in heart rate as dysregulation or every uncomfortable emotion as evidence that the nervous system is unsafe.

Polyvagal Theory and Trauma

Traumatic experiences can alter attention to threat, physiological reactivity, avoidance, sleep, memory, emotion, and relationships. Polyvagal language may help some clients understand why their reactions feel automatic and why reasoning alone does not immediately change them.

However, polyvagal theory does not diagnose trauma and should not replace established assessment of trauma and PTSD.

Regulation-focused work may support preparation for trauma-focused psychotherapy, but it is not equivalent to treatments such as EMDR or trauma-focused cognitive behavioral therapy. A person can learn to recognize nervous-system states and still require direct treatment of intrusive memories, avoidance, beliefs, grief, relationships, or addiction.

Polyvagal Theory, Dissociation, and Shutdown

Numbness, detachment, immobility, reduced speech, fatigue, or disconnection are sometimes described as dorsal vagal shutdown. This language may resonate with a client, but these experiences can also reflect dissociation, depression, medication effects, sleep deprivation, neurological conditions, or other factors.

A label should not replace assessment.

When dissociation is present, practices that intensify internal attention may make symptoms worse. The therapist may prioritize external orientation, movement, open eyes, clear time boundaries, and active choice rather than prolonged stillness or inward focus.

Polyvagal Concepts in Addiction Treatment

Some clients use alcohol, drugs, food, sex, gambling, work, or other behaviors to change an internal state. A substance may temporarily reduce activation, create stimulation, interrupt numbness, or facilitate social connection.

Polyvagal-informed psychoeducation may help the person recognize these functions earlier. It does not mean that addiction is simply a vagus-nerve disorder. (source: National Library of Medicine)

Comprehensive treatment may still require withdrawal management, medication, addiction counseling, relapse prevention, psychiatric care, environmental change, and continuing support.

Breathing, Sound, Movement, and Sensory Practices

Polyvagal-informed programs may include breathing, sound, movement, touch, or sensory exercises. These can influence attention or arousal for some people, but claims that they directly “tone the vagus” or reset the nervous system are often stronger than the evidence supports.

Breathing, sound, touch, and cold exposure can also be uncomfortable, activating, or physically unsuitable. At THE BALANCE, a practice is selected only when it has a clear purpose and produces a useful response for the individual.

Scientific Debate and Limitations

Polyvagal theory has influential supporters and substantial clinical popularity. Porges and colleagues continue to develop and defend the framework, including its emphasis on autonomic state, social engagement, and safety.

Other autonomic neuroscientists have challenged propositions concerning vagal evolution, the proposed hierarchy, distinctions between vagal pathways, and interpretation of measures such as heart rate variability. A wearable HRV reading does not diagnose trauma, safety, or a polyvagal state. Recent expert critiques argue that several foundational claims conflict with comparative anatomy and current physiology.

This debate does not mean that every clinical observation associated with polyvagal practice is useless. It does mean that helpful metaphors should not be presented as settled biological fact.

THE BALANCE distinguishes three levels:

• established knowledge about autonomic regulation and stress physiology;
• clinically useful observations about state, relationship, and regulation;
• theory-specific claims that remain disputed or insufficiently established.

Safety, Choice, and Trauma-Informed Practice

Regulation-focused work should be collaborative. The client needs permission to change position, open their eyes, stop an exercise, decline touch, or choose a different attention anchor.

Potential difficulties include panic, dizziness, dissociation, emotional flooding, shame about being unable to “regulate,” physical discomfort, or excessive monitoring of bodily sensations.

A therapist should not insist that a client remain with an overwhelming state because the nervous system supposedly needs to complete a biological cycle. Significant worsening is reviewed clinically rather than reframed automatically as release. [4]

The wider principles are described under Trauma-Informed Care.

How Progress Is Evaluated

Progress is not measured by claiming that the client has moved permanently into a ventral vagal state.

The team considers whether the work contributes to meaningful changes such as:

• earlier recognition of activation or shutdown;
• greater ability to remain present during therapy;
• more flexible responses to stress;
• reduced automatic avoidance or impulsive behavior;
• improved communication and relational boundaries;
• better recovery after triggering situations;
• reduced reliance on substances or compulsive behaviors for regulation;
• improved sleep or daily functioning;
• progress on appropriate clinical measures.

If the framework increases confusion, self-monitoring, or distress without improving function, it is adapted or removed from the plan.

Polyvagal-Informed Work Within the Balance Model

Selected polyvagal concepts may be incorporated through Assessment and Treatment Planning and the Multidisciplinary Clinical Model.

Depending on the client, regulation-focused work may support:

• individual psychotherapy;
• EMDR or another trauma-focused treatment;
• psychiatric assessment and medication management;
• addiction treatment and relapse prevention;
• somatic and body-based approaches;
• sleep, nutrition, movement, and physical-health support;
• family or relationship therapy;
• continuing-care planning.

The framework is retained only when it improves understanding or treatment. It is not imposed as the master explanation for every symptom.

Fully Private Trauma Treatment in Mallorca and Zurich

THE BALANCE provides fully private residential treatment in Mallorca and Zurich, with each residence and program dedicated to one client.

For executives, founders, public figures, celebrities, internationally mobile families, and HNWI or UHNWI clients, regulation-focused work can be connected to the situations that matter: leadership pressure, travel, family interactions, public exposure, sleep, decision-making, and return to responsibility.

The premium distinction is not a special nervous-system technique. It is the ability to coordinate privacy, setting, pace, professional involvement, and daily practice around one person while maintaining the same clinical standards. (source: MedlinePlus, n.d.)

Preparing for Continuing Care

The aim is not for the client to depend on a therapist to identify every nervous-system state.

Before discharge, the team clarifies which concepts or practices were useful, which were not, how they connect with the broader formulation, and who will continue treatment where needed.

Useful learning is translated into ordinary situations such as conflict, work pressure, travel, cravings, sleep disruption, social contact, and early signs of overload.
