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