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