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