What is PolyVagal Theory?

What is the Vagus Nerve?

The vagus nerve, historically cited as the pneumogastric nerve, is the tenth cranial nerve or CN X, and interfaces with the parasympathetic control of the heart, lungs, and digestive tract

What is Polyvagal theory?

The Polyvagal theory (gr. 'polus', “'many'” + 'vagal', "'vagus nerve'") is a theory that posits that the Vagus nerve is interconnected with and sensitive to influences that flow from the body toward the brain. Polyvagal theory is a theory of the autonomic nervous system that was developed by Stephen Porges. It proposes that the autonomic nervous system, which controls unconscious bodily functions such as heart rate and digestion, has a central role in regulating social behavior and emotion.

According to polyvagal theory, the autonomic nervous system has two main branches: the sympathetic nervous system, which is responsible for the "fight or flight" response, and the parasympathetic nervous system, which is responsible for the "rest and digest" response. The theory posits that the vagus nerve, which is a part of the parasympathetic nervous system, has two branches: the ventral vagus, which is associated with social engagement and connection, and the dorsal vagus, which is associated with withdrawal and self-protection.

Polyvagal theory suggests that the autonomic nervous system plays a central role in shaping our social behavior and emotions. It proposes that the vagus nerve, and particularly the ventral vagus, is involved in regulating social behavior and emotion, and that the sympathetic and dorsal vagal systems are involved in regulation of the body's stress response.

Polyvagal theory has been influential in the fields of psychology, therapy, and neuroscience, and it has implications for understanding and treating a variety of mental health conditions, including anxiety, depression, and trauma.

How does Yoga relate to Polyvagal Theory?

While yoga and polyvagal theory may seem unrelated at first glance, there are some connections between the two. For example, certain practices within the yoga tradition, such as pranayama (breathing exercises) and meditation, may have an impact on the autonomic nervous system and may be able to regulate the body's stress response.

Additionally, the focus on mindfulness and self-awareness in yoga practice may help individuals to better understand and regulate their own emotional states, which is a key aspect of polyvagal theory. Research has also suggested that regular yoga practice may be able to improve physical and mental health by regulating the body's stress response and promoting a sense of relaxation and well-being.

Overall, while yoga and polyvagal theory are separate fields of study, there are some connections between the two and research suggests that yoga practice may be able to support the regulation of the body's stress response and promote physical and mental well-being.
