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