Anxiety, the nervousness or agitation that we sometimes experience, often about something that is going to happen, is a natural part of life. We a ll feel anxious at times, maybe when we think about our upcoming visit to the dentist or the presentation we have to give to our class next week. Anxiety is an important and useful human emotion; it is associated with the activation of the sympathetic nervous system and the physiological and behavioral responses that help protect us from danger.
