Window of Tolerance

Window of tolerance, also called zone of optimum arousal: The windowof tolerance, a concept developed by Dan Siegel, MD, describes the ideal emotional/physiological state to  manage stress and challenges without becoming overwhelmed — when we feel grounded and can manage our emotions effectively. Research notes our window of tolerance balances hyperarousal (heightened agitation, anxiety, anger, feeling overwhelmed) and hypoarousal (numbness, disassociation, exhaustion, depression, lacking energy). Hypoarousal can occur when hyperarousal overwhelms. Both states can trigger a fight-or-flight response (FFN) or cause us to lose access to executive functions, panic, self-sabotage, and act recklessly. How wide our window is can depend on childhood experiences, support from family and friends, environment, or ability to self-regulate emotions. How narrow can depend on lack of sleep, illness, substance use, age, history of dealing with triggering events, existing mental health condition, or trauma. “Narrowing” experiences can alter therapy’s effectiveness and prevent us from learning, coping, and productivity. Expanding the zone takes building supportive relationships with trusted people, calming exercises, physical exercise, and professional help
