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