Modern understanding of anorexia nervosa increasingly centers on the nervous system — specifically, the chronic dysregulation that underlies many anorexia nervosa presentations.
The Nervous System in Anorexia Nervosa
The autonomic nervous system has two primary states relevant to anorexia nervosa:
Sympathetic activation ('fight or flight'): When chronically activated, drives anxiety-type anorexia nervosa
Parasympathetic ('rest and digest'): The recovery state — undermined by anorexia nervosa
Dorsal vagal shutdown: A third state — freeze/collapse — associated with depression-type anorexia nervosa
Signs of Nervous System Dysregulation in Anorexia Nervosa
Chronic hyperarousal (always 'on edge'), difficulty relaxing even in safe environments, and feeling perpetually exhausted despite rest.
Regulating the Nervous System for Anorexia Nervosa
- Breathwork: Directly activates the parasympathetic nervous system
- Cold exposure: Controlled cold activates the vagus nerve, improving anorexia nervosa
- Safe social engagement: Co-regulation through trusted relationships
- Movement: Discharges sympathetic activation accumulated in anorexia nervosa
