Functional neuro-autonomic and postural dysregulation syndrome involving vagus nerve inhibition, fascial compression.The body operates in a freeze–survival mode: low metabolism, poor digestion, shallow breathing, and emotional hyper-reactivity. Conventional vagus stimulation (cold, humming, strong breathing) backfires, confirming higher-level dysautonomia. Organ structure intact — dysfunction is signal-level, not tissue damage. System-Wise Effects Digestive: Reflux without burn, poor enzyme and bile release, mild hernia but no obstruction. PPIs/prokinetics ineffective. Respiratory: Shallow chest breathing, diaphragm rigidity; relief in supported cow or fetal posture. Neurological: Autonomic surges within seconds; palpitations, brain fog, sensory overload. Musculoskeletal: Tight rib-pelvic chain, fascia locked; posture collapse. Psychological: OCD-like impulses, sympathetic drive, emotional addiction loops. Endocrine: Functional suppression.
