Window of tolerance PDF, an acronym for “polyvagal flexibility,” is a resource for managing the nervous system. This document is rooted in the Polyvagal Theory, developed by Dr. Stephen Porges, and is thus an essential tool for understanding the body’s response to stress.
The window of tolerance PDF offers guidance on maintaining a state of balance within the nervous system, by teaching the reader how to navigate between hyperarousal and hypoarousal states. The concept of a “window of tolerance” refers to the optimal range of physiological arousal for effective functioning, lying between states of high stress and low energy.
