The zone where you can experience emotions without becoming overwhelmed (hyperarousal) or shutting down (hypoarousal).
The window of tolerance, a concept developed by Daniel Siegel, describes the zone of arousal in which you can function effectively. Within this window, you can think clearly, feel emotions without being overwhelmed, and respond rather than react.
Above the window is hyperarousal: anxiety, panic, racing thoughts, emotional reactivity, feeling 'too much.' Below is hypoarousal: numbness, disconnection, fatigue, feeling 'too little.' Both states impair your ability to process experience and make good decisions.
Trauma, chronic stress, and mental health conditions can narrow this window, making it easier to get pushed into hyperarousal or hypoarousal. The therapeutic goal is to gradually widen the window—increasing your capacity to stay present with increasingly intense experiences.
ILTY helps you recognize when you've left your window of tolerance and offers appropriate support. If you're in hyperarousal (panicking, spiraling), ILTY helps you ground and calm. If you're in hypoarousal (numb, disconnected), ILTY gently re-engages you.
In your window: you're stressed about a deadline but can think through a plan. Hyperarousal: you're so anxious about the deadline that you can't focus at all, your heart is pounding, you're snapping at everyone. Hypoarousal: you're staring at the screen, feeling nothing, unable to care or start.
Your autonomic nervous system regulates your stress response. Dysregulation means your body stays in fight-or-flight even when there's no danger.
The ability to manage and respond to emotional experiences in healthy ways, rather than being controlled by them.
Your body's automatic stress response that prepares you to face danger or escape it—often misfiring in modern life.
A body-oriented therapy that addresses trauma and stress stored in the nervous system through physical sensation awareness.
Understanding concepts is valuable. Applying them to your own life is where the change happens. ILTY helps you do both.
