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