polyvagal theory 101
learn about your nervous system, reclaim a new power of being alive
When we hear the term "theory," we might think it means something speculative or unproven. However, in the scientific world, a theory is a well-established framework based on extensive research and evidence. The Polyvagal Theory, developed by Dr. Stephen Porges, is one such accepted and influential concept that has profound implications for understanding our nervous system and promoting healing.
What is the Polyvagal Theory?
The Polyvagal Theory explains how our autonomic nervous system (ANS) regulates our physiological state and influences our behavior and emotional experiences. The ANS has traditionally been understood to consist of two branches: the sympathetic nervous system (SNS), which prepares us for "fight or flight," and the parasympathetic nervous system (PNS), which promotes "rest and digest." The Polyvagal Theory adds a new layer of understanding by introducing the concept of the vagus nerve's two distinct pathways.
The Vagus Nerve and Its Pathways
The vagus nerve, also known as the "wandering nerve," plays a crucial role in regulating our internal organs and emotional responses. According to the Polyvagal Theory, the vagus nerve has two branches:
1. Dorsal Vagal Pathway: This older, primitive pathway is associated with immobilization and shutdown responses. It activates during extreme stress or trauma, leading to feelings of disconnection or numbness. This response of dorsal is a survival response, but when the organism is in a regulated state due to a sense of safety in its environment, positive regulatory pathways in the dorsal circuit are activated.
2. Ventral Vagal Pathway: This newer pathway supports social engagement, calm states, and connection. It allows us to feel safe, engage with others, and promote healing and relaxation.
Another response - Sympathetic resonance
In addition to the vagal system, we have another branch of the autonomic system that stands alone known as the Sympathetic Nervous System (SNS). This correlates with the Fight-Flight response. When there is a communication from the senses of the body that there is a threat, the brain will then send information through the body to activate this response. This will then build even more tension and release stress hormones that create an activation of stress and anxiety. When in this state we cannot access higher circuits of our brain and live in a survival response.
The Importance of the Ventral Vagal Pathway
The Polyvagal Theory emphasizes the importance of the ventral vagal pathway in fostering a sense of safety and promoting optimal health. When this pathway is active, we are more likely to experience positive emotions, form healthy relationships, and effectively manage stress. This pathway plays a vital role in regulating our body's response to stress and trauma, making it a key focus for therapeutic interventions. It is also key to note that this pathway is responsible for communicating signals to the brain about the environment, so the brain understands what is taking place in one’s environment. It is estimated that 80% of the input the brain receives is from the body (the fascial interoceptive receptors). Our mission is to teach people how to awaken these pathways for new information to be communicated to the brain, enabling the brain to activate in higher circuits of the brain that come online when ventral is activated.
How Polyvagal Theory Relates to Fascia Awakening
Understanding the Polyvagal Theory can enhance our approach to fascia awakening by highlighting the importance of creating a safe and supportive environment. It’s important to note that most people don’t know what true safety feels like in their body, and what may be possible in their mind’s ability to expand when this comes in.
Some Psycho-Somatic Signs that you are NOT embodied in safety:
Tension and rigidity in the body
Inflammation in the body / brain
Lack of self-awareness / emotional intelligence
Inability to sense and feel different parts of the body, such as where they are in space and how they may feel underneath the skin
Negativity Bias - Narrow minded, Limited perception
Victim consciousness
Lack of well-being in your body
Techniques that activate the ventral vagal pathway, such as fascial awakening and release practices with mindful attention, can help release tension in the body, sending signals of safety to the brain for new states of well-being. By aligning our practices with the principles of the Polyvagal Theory, we can facilitate deeper healing and more positive life experiences, elevating those around us and supporting the evolution on this planet.
