Window of Tolerance Mapper

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.

Step 1 — Which zone are you in right now?

Hyper-arousal zone — above the window

Anxiety, panic, rage, overwhelm, racing thoughts, hypervigilance. Too much activation to think clearly.

Window of Tolerance — optimal zone

Present, grounded, thinking clearly, able to feel emotions without being overwhelmed, connected to others.

Hypo-arousal zone — below the window

Numbness, shutdown, dissociation, fatigue, feeling empty, withdrawal, inability to think or connect.

Step 2 — What pushes you out of your window? Hyper-arousal triggers (people, situations, sensory inputs, thoughts) Hypo-arousal triggers (things that shut you down)
Step 3 — What brings you back into your window? Down-regulation strategies (to return from hyper) Up-regulation strategies (to return from hypo)
Step 4 — Estimate your current window width

How wide is your current capacity to tolerate stress before going outside the window?

How to widen the window over time

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.
