What is window of tolerance?
Inside the window, you can feel emotions and still function. Above it is hyperarousal: panic, anger, racing thoughts. Below it is hypoarousal: numbness, shutdown, disconnection.
Key things to know
Trauma and chronic stress narrow the window, so smaller triggers push you out of it. This explains reactions that seem disproportionate to the trigger.
