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