The “Window of Tolerance” is a model that I use very often in my work with clients, to provide an explanation for many common experiences such as, triggers, depression, anxiety, and the impacts of stress. The Window of Tolerance was originally developed by Dr. Dan Siegel (1999), and has been adapted many times by other trauma researchers and therapists since.

This model describes what happens when provides a way to understand how we organize and manage incoming information and what happens when it becomes unmanageable; another way to understand our nervous system responses to our environment and our lives.
