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