Polyvagal Theory: Understanding Your Three Nervous System States
Dr. Stephen Porges' groundbreaking theory explains why we react to stress the way we do — and how to shift states intentionally.

The autonomic nervous system governs every involuntary process in the body, from heart rate and digestion to immune function and stress response. Polyvagal Theory, developed by Dr. Stephen Porges, reveals that the vagus nerve acts as the body's master regulator, determining whether we exist in a state of safety, mobilization, or shutdown. Learning to regulate the nervous system is perhaps the most impactful skill for overall health and performance.
Science Snapshot
The vagus nerve is the longest cranial nerve, connecting the brain to the heart, lungs, and gut. Higher vagal tone is associated with better emotional regulation, lower inflammation, and improved cardiovascular health.
