What is polyvagal-informed therapy?

Polyvagal theory, developed by Stephen Porges, describes how the autonomic nervous system shifts between states of safety, mobilisation and shutdown. Polyvagal-informed therapy is the clinical use of that map: instead of asking only "what is this client thinking?", you also ask "what state is this client's body in, and what does that state make possible?"

The three states in plain language

In a ventral vagal state, the system is settled enough for connection — the client can reflect, take in a reframe, and stay curious about themselves. In a sympathetic state, the system mobilises: energy rises, thinking narrows, and the client argues, justifies or flees the topic. In a dorsal state, the system shuts down: flat affect, fog, hopelessness, the sense of not being in the room.

A client in shutdown is not resisting the work. Their body has decided the work is not survivable right now.

Why it changes clinical work

Insight requires a ventral state. This single idea reorganises a practice. Interpretations delivered to a braced or collapsed nervous system are filed as threat or noise — which is why a client can agree with you completely and return unchanged. Polyvagal-informed therapists sequence sessions around state first and content second: settle, then explore.

What it looks like in the room

• Tracking state shifts moment to moment — the sigh, the jaw setting, the eyes going flat
• Slowing or pausing content when the client leaves a settled state
• Using voice, posture and pacing to offer the client's system cues of safety
• Treating your own regulation as a clinical instrument, not a personal luxury

Learning the approach

The theory can be read in a weekend; the skill cannot. Polyvagal-informed work is learned through live practice — having your own state tracked, and tracking others with feedback. It is especially powerful with couples, where two nervous systems escalate or soothe each other in real time.
