The 'window of tolerance' — a concept from trauma therapy — explains why postpartum depression pushes us into states where we can't function well, and how to expand our capacity.
What Is the Window of Tolerance?
The window of tolerance is the zone of arousal in which we function optimally. Outside it:
- Hyperarousal (postpartum depression 'too high'): Panic, overwhelm, rage, anxiety — above the window
- Hypoarousal (postpartum depression 'too low'): Numbness, dissociation, shutdown, depression — below the window
How Postpartum Depression Narrows the Window
Trauma and chronic postpartum depression narrow the window of tolerance, making us more easily triggered into dysregulated states by smaller stimuli.
Widening Your Window with Postpartum Depression
Trauma-informed therapy specifically works to widen the window of tolerance — building capacity to experience postpartum depression triggers without dysregulation.
Titrated exposure (small doses of difficult material), somatic practices, and skill-building all contribute to window expansion.
