Polyvagal Theory — explained simply for everyday life

Stephen Porges' Polyvagal Theory describes how our autonomic nervous system, via the vagus nerve, constantly scans our surroundings for safety or danger — a process Porges calls “neuroception”.

This gives rise to three basic states: safety and connection, mobilisation (fight or flight), and shutdown (freeze). Many people under chronic stress are stuck in the lower states without realising it.

Understanding these states removes self-blame: your reactions aren't a character flaw, they're protective mechanisms — and they can be regulated again with focused work.
