Understanding Polyvagal Theory and the Nervous System

Polyvagal theory explains how our nervous system works and influences our thoughts, feelings, and behaviors. It is composed of three organizing principles: hierarchy, neuroception, and co-regulation. Hierarchy refers to the different states our nervous system can be in, such as the regulated ventral state, the fight-or-flight sympathetic state, or the shutdown dorsal state. Neuroception is the nervous system's way of listening and gathering information from our bodies and the environment to determine whether it's safe or dangerous. Co-regulation is the biological need to connect with others and experience safe interactions, which helps regulate our nervous system. Understanding polyvagal theory helps us become more aware of our nervous system's responses and be active operators in regulating and managing it.
