Often a symptom of other health conditions, nervousness can be described as a general condition of unrest and irritability. Nervous people often find themselves in a constant state of "fight or flight," in which the nervous system prepares the body for threatening situations. During this process, the heart rate increases, the pupils dilate, respiratory rate increases, appetite decreases, and digestive activities are repressed.

Nervousness, whether the result of an actual or imagined threat, takes a toll on the body if it continues for a prolonged period. Symptoms of chronic nervousness may include Fatigue, Headache, inability to concentrate, Insomnia, Pain, weakness, sweating, fear, and muscle aches. Prolonged nervousness is almost always a symptom of an underlying organic and/or psychological disorder.
