The 'window of tolerance' — a concept from trauma therapy — explains why adverse childhood experiences 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 (adverse childhood experiences 'too high'): Panic, overwhelm, rage, anxiety — above the window
- Hypoarousal (adverse childhood experiences 'too low'): Numbness, dissociation, shutdown, depression — below the window
How Adverse Childhood Experiences Narrows the Window
Trauma and chronic adverse childhood experiences narrow the window of tolerance, making us more easily triggered into dysregulated states by smaller stimuli.
Widening Your Window with Adverse Childhood Experiences
Trauma-informed therapy specifically works to widen the window of tolerance — building capacity to experience adverse childhood experiences triggers without dysregulation.
Titrated exposure (small doses of difficult material), somatic practices, and skill-building all contribute to window expansion.
