Poly Vagal Theory

What is Poly Vagal Theory?

The polyvagal theory helps us understand how it is that trauma lives in the body and continues to shape our world. 

It explains the psychological, physiological, and biobehavioral experiences that come after a traumatic experience. The theory is used to look at how the autonomic nervous system plays a part in people’s lives who have experienced trauma. 

Before we dive into it, it’s important to note that everyone has experienced trauma in their life. Just because someone’s situation may seem worse does not mean that another person’s trauma is invalid. Again, everything has to do with the response of the body. When our body experiences trauma, our autonomic nervous system changes the way it regulates the body’s organs.
