Have you ever found yourself at a social event and feeling uncertain about being there, or even in danger, but unsure as to why? You may look around and nobody else seems to be bothered.
You may not realize this, but when you are walking around the world, your body is taking in many social cues about your environment. When you are interacting with others, your body is picking up facial expressions, tones of voice and bodily movements. All these cues continuously interact with your nervous system, informing your body if the environment is a safe place where you can connect with others, or a dangerous place where you either have to run, fight or freeze. The interaction with the environment and the body’s way of relating to it is known as the Polyvagal Theory, a term coined by Dr. Stephen Porges. The term that describes how our nervous system assesses whether people or places are safe, dangerous or life threatening is known as Neuroception.
What is the Polyvagal Theory?
The Polyvagal Theory explains how our nervous system responds to stress or danger. It has a three-part hierarchical system, all of which involve a cranial nerve called the vagus nerve. The vagus nerve (Vagus: Latin for wandering) connects (or wanders) from the brain through all major systems in the body: the stomach and gut, heart, lungs, throat, and facial muscles!
The three-part hierarchical system means that only one part can work at any given time, while the other two parts take the back seat.
1. The ventral vagal system, also known as the safety system, green zone or social engagement system
When this system is engaged, the person feels safe, loved, and able to share feelings with others and be social while maintaining eye contact. The person is attuned to other people’s facial expressions and tone of voice. Heart rate is regulated and one is able to take in a full breath and breathe slowly. The person has a healthy blood pressure, good digestion, a healthy immune system and good sleep. He or she is able to reach out to others and ask for help or support.
2. The activation system, also known as the sympathetic nervous system, yellow zone or fight or flight response
When this system is in charge, the person doesn’t feel at ease, doesn’t feel that others can be trusted, is constantly scanning the room for danger, and is listening to sounds of danger instead of friendly voices. The person’s breath is shallow and his or her heart is racing. In such a state, the person may have elevated blood pressure, poor digestion, poor immune system and poor sleep. He or she may report more headache and back tension.
3, The dorsal vagal system, also known as immobilization, freeze system or the red zone
When this system is engaged, as a last resort if the person is not able to fight or run away, the body shuts down or collapses. Heart rate slows down, and breathing slows and becomes shallow to the point where the person may feel like fainting. The person may feel like they dissociate, report a foggy memory and lack energy. The person may report weight gain, low blood pressure and stomach problems. Sometimes, when a person is in this state, he or she has reported feeling ashamed, trapped or “too small to be seen or heard.” Quite often, patients with post-traumatic stress disorder talk about how they “froze” when the trauma happened and feeling shame: both of which can be explained by the third system kicking in as a response to danger.
How Understanding Polyvagal Theory Can Help You Regulate Stress?
The better you understand which one of the three states you are in, the more you are able to engage yourself in self-regulation and returning to the green state: the social engagement system.
Here are a few things you can do to re-engage in the social system:
- Change your breathing so that exhalations are longer than inhalations. This is often taught in yoga practices. Doing this re-engages the ventral part of the vagus nerve, which, in turn, slows down the heart rate.
- Seek environments that are soothing and where you feel safe, loved and connected. For some people, it is walking in nature, for others, it is spending time with their pets or loved ones.
- Listen to soothing music.
For some people, seeking therapy also helps, especially when there have been traumatic events that make personal attempts to engage the green state unsuccessful.
