Dan Siegel's Window of Tolerance describes the arousal zone where you can function optimally — not too activated, not too shut down. Trauma typically narrows this window. This tool helps you map your personal window, identify your triggers for leaving it, and build strategies to widen it.
Anxiety, panic, rage, overwhelm, racing thoughts, hypervigilance. Too much activation to think clearly.
Present, grounded, thinking clearly, able to feel emotions without being overwhelmed, connected to others.
Numbness, shutdown, dissociation, fatigue, feeling empty, withdrawal, inability to think or connect.
How wide is your current capacity to tolerate stress before going outside the window?
Window expansion happens through repeated experience of going slightly outside the window and returning — not by forcing yourself to endure overwhelming experiences. Titrated exposure, somatic therapy, and consistent use of your identified strategies gradually increase tolerance.
