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