The concept of the window of tolerance describes the range of emotional and physiological arousal within which a person can respond to situations with clarity and regulation. When we are moved outside of this range, into hyperarousal (fight-or-flight) or hypoarousal (freeze or shutdown), our behaviour becomes driven by previously learned survival mechanisms rather than conscious choice. The creator, Dr. Seigel argued the impact of how early relational experiences shape nervous system regulation. He highlighted that supportive and attuned environments help children develop a wider window of tolerance, while trauma, neglect, or chronic stress can narrow it, making the nervous system more reactive to perceived threats.
The window of tolerance is not fixed. It can expand with intentional practice and choices. Investing in a network of support, developing mindfulness, and learning self-compassion all teach your nervous system that it is safe to stay present, even in discomfort. Rest, movement, nourishment, and stability in your daily life also strengthen this capacity. As your window widens, you become better able to recover from stress, stay grounded during conflict.
Learning about your window of tolerance gives language to what happens inside you when things feel “too much” or “not enough.” This awareness allows you to notice the early signs of dysregulation and make choices that helps you feel re-regulated. Over time, this builds a sense of trust in your own capacity to validate and navigate your distress.
