Polyvagal Theory

Polyvagal theory emphasizes autonomic state as an intervening variable between stimulus and response. Different autonomic histories are used to explain why people exposed to the same mold or Lyme-related factors can have different symptom profiles. Polyvagal theory was developed by Stephen Porges. The theory links autonomic physiology and vagal regulation to social behavior, emotional regulation, trauma responses, and safety-threat states. Autonomic state influences perception, response patterns, social behavior, defensiveness, and emotional regulation. Polyvagal Theory is used to explain hierarchical autonomic states in response to perceived safety or danger. High-stress habituation can make minor inputs appear like emergencies to the body. The article says the body cannot fully heal and run a full threat response at the same time. Polyvagal theory describes older survival circuits that can be repurposed for play, intimacy, restoration, and social connection in safe states.
