Yoga teacher Jenni Rawlings and Exercise Science professor Travis Pollen discuss the nervous system and take a science-based look at the popular polyvagal theory with Dr. Laura Baehr, PT, DPT, and PhD candidate in Rehabilitation Sciences.

Points of discussion include:

• A brief primer on nervous system structure and function
• The relationship between the “fight or flight” and “rest and digest” nervous system responses
• The definition of “resilience” and how a movement practice can enhance this quality
• A brief summary of polyvagal theory, which was introduced by Stephen Porges in 1994
• The widespread prevalence of polyvagal theory and its concepts today in yoga, yoga therapy, mental health fields, somatics-based practices, and more
• Does increased vagal tone correlate with increased emotional resilience and vice versa, as put forth by polyvagal theory?
• Is heart rate variability an accurate measurement of vagal tone or vagus nerve activation?
• Can we realistically stimulate the vagus nerve in isolation in yoga and movement settings?
• The connection between polyvagal theory and beliefs that emotions and trauma can be stored in the tissues of the body
• …And much more!

Enjoy this engaging and eye-opening discussion for yoga, movement, and fitness geeks!
