In this episode, Ellis and Dr. Rob dive deep into the intricacies of the sympathetic and parasympathetic nervous systems, also known as the polyvagal system. This theory explains how these systems impact our response to stress, trauma, and everyday life. We discuss the fight or flight response, the role of the brainstem and primitive reflexes, and how imbalances in these systems can affect everything from infant development to adult mental health issues like PTSD and POTS. Whether you're curious about how your nervous system works or looking for insights into managing anxiety and stress, this episode is packed with valuable information.
