How is polyvagal theory used in therapy?

Polyvagal theory is used to help clients understand their automatic stress and trauma responses, which can feel confusing or out of control. Therapists draw on it to explain why certain situations trigger shutdown or hyperarousal, and to introduce practices that support the nervous system in returning to a calmer, more regulated state. It is particularly used in trauma-informed and somatic approaches.

Is polyvagal theory the same as somatic therapy?

No, but they are closely related. Polyvagal theory is a scientific framework that explains nervous system responses. Somatic therapy is a therapeutic approach that works with the body. Many somatic therapists use polyvagal theory as the theoretical basis for their work, but the two are distinct. A therapist can use polyvagal principles within a range of therapeutic approaches.

How do I find a polyvagal-informed therapist through It's Complicated?

It's Complicated matches clients with verified trauma-informed and somatic practitioners who use polyvagal theory across Europe. You complete a short survey about your situation and what you're looking for, and a psychologist identifies a shortlist of suitable therapists. You choose from that shortlist and book directly. Online and in-person sessions are available.

Do I need to understand polyvagal theory before starting therapy?

No prior knowledge is needed. Therapists who use polyvagal theory typically introduce its key ideas in plain language as part of the therapeutic work, often as a way of helping clients make sense of their own responses. Understanding why your nervous system reacts the way it does can itself be therapeutic, reducing shame and increasing a sense of agency.

Q: What is polyvagal theory?

Polyvagal theory is a scientific framework that explains how the nervous system responds to safety, danger, and threat. It describes three states: a calm, connected state; a mobilised fight-or-flight state; and a shutdown or freeze state. Therapists use this framework to help clients understand why they respond the way they do under stress, and to support nervous system regulation in treatment.

Learn more about polyvagal theory

Polyvagal theory is a scientific framework that describes how the autonomic nervous system responds to safety, danger, and threat. It identifies three distinct states: a calm, socially engaged state; a mobilised fight-or-flight state; and a shutdown or freeze state. Each state is governed by a different branch of the vagus nerve and produces different physiological and psychological responses. Therapists use polyvagal theory to help clients understand their automatic reactions to stress and trauma. Knowing which state you are in, and why, can make confusing or distressing responses feel more understandable and less shameful. It also informs the practical tools used to support nervous system regulation in treatment.

In a polyvagal-informed therapeutic approach, the therapist uses the framework to map the client's nervous system responses and identify what supports regulation. This is not a protocol but a way of understanding and working with the body's automatic reactions. Sessions may involve:

Psychoeducation: learning about the three nervous system states and recognising which one you are in at different moments
Tracking: noticing physical sensations and body signals that indicate a shift between states
Regulation practices: breathing, movement, voice, and connection-based tools that help the system return to a calmer state
Working with triggers: understanding what cues the nervous system into threat responses, and gradually expanding the window of tolerance
Building safety: developing the conditions, internal and relational, that allow the nervous system to settle

Polyvagal theory is most commonly integrated into somatic, trauma-informed, and body-based therapeutic approaches. It is rarely the sole framework but often the explanatory layer beneath other methods. For those experiencing trauma-related symptoms, this work requires careful pacing. If you are in acute distress related to trauma, please seek support from a qualified mental health professional before beginning.

Polyvagal theory is most clinically relevant for presentations where nervous system dysregulation is a central feature. Trauma Trauma is the primary application of polyvagal-informed therapy. Traumatic experiences dysregulate the nervous system, leaving people stuck in fight-or-flight or freeze states long after the original event. Polyvagal theory provides both a map for understanding this and a framework for gently restoring regulation. PTSD Post-Traumatic Stress Disorder (PTSD) involves chronic nervous system dysregulation: hypervigilance, intrusive responses, and emotional numbing. Polyvagal-informed approaches address these at the level of the autonomic nervous system, supporting the body's capacity to process and integrate what happened. Anxiety Anxiety involves a nervous system that is persistently oriented toward threat. Polyvagal theory helps clients understand this orientation as an adaptive response rather than a personal failing, and provides practical tools for expanding the capacity to tolerate uncertainty and remain regulated under pressure. Complex PTSD Complex PTSD (C-PTSD), which develops from prolonged or repeated trauma, involves deeply embedded patterns of nervous system dysregulation. Polyvagal-informed therapy is well-suited to this presentation because it prioritises stabilisation and works at a pace that the nervous system can tolerate.
