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