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