Hyperarousalhyperarousal

Hyperarousal is a state of intense activation in which the nervous system rises above its window of tolerance. In this state the body is as if on alert; the heart races, the mind runs, and a person may feel tense, restless, or out of control. Hyperarousal is a state in which the sympathetic system is dominant. This state is a sign of the high response the nervous system gives to danger. A person who has risen above their window usually first needs a ground that will help them settle.
