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