Polyvagal Theory
A clearer guide to Polyvagal Theory, its terminology and the science behind it
Polyvagal Theory is often used to help explain why our bodies can feel calm and connected at some times, alert and ready for action at others, or withdrawn and difficult to engage when things feel overwhelming.
The terminology can sound complicated, so this resource breaks concepts such as ventral vagal, sympathetic mobilisation, dorsal vagal, neuroception, co-regulation and heart-rate variability into everyday language, with practical examples showing what they might look like in real life.
It also explores an important distinction: some of the underlying autonomic nervous-system science is well established, while parts of Polyvagal Theory’s specific biological explanation remain scientifically debated. The resource therefore separates what we know, what the theory proposes, and how its ideas may still be useful therapeutically.
It includes:
- A simple introduction to the autonomic nervous system
- What “polyvagal” actually means
- The three-state model explained clearly
- Ventral vagal and social engagement
- Sympathetic mobilisation and fight-or-flight responses
- Dorsal vagal and “shutdown” language
- Neuroception in everyday language
- Co-regulation with real-world examples
- Heart-rate variability and “vagal tone”
- Why therapists may find the framework useful
- The scientific debate surrounding the theory
- Neurodivergence and communication
- Examples of more accurate ways to use polyvagal language
An accessible and balanced introduction for anyone who wants to understand Polyvagal Theory without needing a background in psychology, therapy or neuroscience.
