Biofeedback is useful for monitoring many physiological systems and raising your body awareness, its responses to the environment, and improving your ability to identify how thoughts are linked to our bodies reactions in stressful circumstances. Biofeedback uses tools to monitor physiological responses and display them in real time.
For example, biofeedback might use signals of your heart rate and provide visible or auditory feedback to make you more aware of your physiological responses…in a way you may not have been aware before. Like a pitcher learning to throw a ball across a home plate, the biofeedback trainee, in an attempt to improve a skill, monitors the performance. When a pitch is off the mark, the ballplayer adjusts the delivery so that he performs better the next time he tries. When the light flashes or the beeper beeps too often, the biofeedback trainee makes internal adjustments which alter the signals.
The biofeedback therapist acts as a coach, standing at the sidelines setting goals and limits on what to expect and giving hints on how to improve performance.
