Dr. Cathleen King explains how nervous system regulation can unlock immune function, detox pathways, and healing in chronic illness. Understand how nervous system dysregulation keeps the body stuck in survival mode, blocking immune function, detoxification, and long-term healing even when the “right” treatments are in place. Discover why simple practices like breathwork, eye movements, and body awareness can trigger real physiological shifts—and why temporary flare-ups can signal progress, not failure. Learn how mapping your nervous system state using polyvagal principles helps you choose the right response—calming or activating—based on what your body actually needs.
