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