POLYVAGAL THEORY & NERVOUS SYSTEM STATES

Your Nervous System Has Three Gears. Most People Are Stuck in the Wrong One.

Dr Stephen Porges' Polyvagal Theory has revolutionised our understanding of the autonomic nervous system, trauma, and chronic illness. Beyond the simple sympathetic/parasympathetic divide, Porges identified three hierarchical states: ventral vagal (social engagement, safety, healing), sympathetic (fight or flight), and dorsal vagal (freeze/shutdown/dissociation). Chronic illness, trauma, and toxic exposure push the nervous system into lower states where healing is biologically impossible. Neuroception — the nervous system's subconscious threat detection — explains why people feel chronically unsafe even in objectively safe environments. Understanding these states is essential for anyone who cannot heal despite doing all the right things.
