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