How is biofeedback accomplished and what is the goal of this stress-management technique?
Biofeedback is a method of obtaining feedback, or information, about some physiological activity occurring in the body. An electronic monitoring device attached to the body detects a change in an internal function and communicates it to the person through a tone, light, or meter. By paying attention to this feedback, most people can gain some control over functions previously thought to be beyond conscious control, such as body temperature, heart rate, muscle tension, and brain waves. The goal of biofeedback for stress reduction is a state of tranquility, usually associated with the brain's production of alpha waves (which are slower and more regular than normal waking waves)
