Breathing is an autonomic function that people can control at will. We can easily change the rate, pattern, and depth of our breathing to experience powerful results. We can “log onto” the body’s internal Internet and send messages in the form of respiratory information in a nonverbal, body-based language that the brain can understand. In moments of high stress (when words fail us) we can rely on this powerful tool to reassure our minds that we are safe and sane. Biofeedback teaches us how to tap into this natural resource.
