Polyvagal Theory provides insights into the body’s autonomic nervous system and its influence on emotional regulation and social behaviour. By understanding the body’s responses to stress and safety cues, individuals can learn to regulate their nervous system and foster a sense of safety and connection through somatic exercises and also tracking one’s states and learning how to regulate themselves..
Developed by Stephen Porges, examines the role of the autonomic nervous system
Here are the key ideas of Polyvagal Theory:
- The Hierarchy of the Autonomic Nervous System: Polyvagal Theory expands on the traditional view of the autonomic nervous system (ANS) having two branches: sympathetic (fight-or-flight) and parasympathetic (rest-and-digest). It proposes that the parasympathetic nervous system has two further branches:
- Ventral Vagal System: This part supports social engagement, safety, and connection. When we feel safe, our ventral vagus nerve calms us down, allowing us to be social and cooperative.
- Dorsal Vagal System: This part focuses on immobilization in response to perceived threats. If we sense danger but can’t fight or flee, our dorsal vagus nerve shuts down non-essential functions to conserve energy. In extreme cases, it can even trigger fainting.
- Neuroception: This refers to our unconscious system’s continuous scanning of the environment for safety cues. Based on these cues, our nervous system decides how to react, activating the ventral or dorsal vagal system as needed.
- Co-regulation: Polyvagal Theory suggests that we can regulate our nervous system state through social connection with others. Calming cues from a trusted person, like a soothing voice or gentle touch, can activate our ventral vagus nerve and promote feelings of safety and well-being.
Here’s how Polyvagal Theory can be applied in real life:
- Imagine you’re walking home alone at night and hear footsteps behind you. Your nervous system will likely switch to the dorsal vagal state, making you freeze or become hypervigilant.
- Conversely, spending time with a loved one who makes you feel safe and secure activates your ventral vagus nerve, promoting relaxation and social connection.
