Whats a biofeedback? how is it used? whats the program include?

Biofeedback is a type of therapy in which people are trained to be able to exercise some control over the way their bodies work, especially over the way their bodies react to stress. In our hectic society, many people find themselves 鈥渟tressed out鈥?too much of the time, and their bodies show the results of this over-reaction to stress by developing anxiety, headaches, digestive trouble, sleeplessness, high blood pressure, and other nasty symptoms.

Biofeedback uses electronic sensors to accurately measure and 鈥渇eed back鈥?to the individual information about their bodies to which they ordinarily would not have access. We all use forms of biofeedback in our daily lives, every time we take our temperatures or check our weight. In clinical biofeedback, the measured bodily processes are muscle activity, skin temperature, skin conductivity, pulse volume, heart rate, and other such physiological data. These signals can tell us the degree of relaxation or tension we are producing, and when we become aware of what is happening in our bodies by seeing it reproduced on a computer screen, the biofeedback therapist can help us learn how to alter or change the signals, and thereby, how to correct bodily over-reactions. This process is called self-regulation. We learn from biofeedback to be more aware of what our bodies are doing, and to bring our reactions under our control.

By converting physiologic data -- heart rate or blood pressure, for example -- into a sensory signal -- typically a tone -- you can learn to modulate the tone by relaxation, thus lowering your heart rate or blood pressure. Over time, you can learn to do this without the signal.
