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