The three states

In 1994 a scientist named Stephen Porges proposed a map of the nervous system that therapists have been using ever since, because it explains something every one of us has felt and nobody had named.

He called it Polyvagal Theory. The vagus nerve, which runs from the brainstem to the gut, has two branches, and with the fight-or-flight system they give the body three states. The first is safe and social: the face is soft, the voice has music in it, you can connect. The second is mobilized: fight or flight, heart up, jaw set, ready. The third is shutdown: the body goes still, flat, far away, the way an animal plays dead. The body moves between the three not by deciding but by sensing, below thought, whether it's safe. Porges called that sensing neuroception.

The science has been argued about, and some of the anatomy is disputed. But as a map of lived experience it's the most useful thing I know. It explains why you can't think clearly in a fight. Why some people freeze instead of fighting and then feel ashamed of it, when it was the body doing exactly what bodies do. And why a kind face and a slow voice do more for a frightened person than any argument.

The key for the month of Breathing is this: the way back up the ladder, from shutdown to mobilized to safe, runs through the body. A long exhale. A hum, which vibrates the vagus. Eyes meeting kind eyes. Warmth. These are not soft extras. They are the switches. And the person who learns to read their own three states, and to move between them on purpose, has a kind of freedom most people never get.
