Biofeedback is a mind-body technique in which a practitioner uses a special monitoring machine to teach people how to control bodily functions such as heart rate, blood pressure, skin temperature, and muscle tension, in order to improve their health and well-being and alleviate emotional trauma. It gives instant information feedback about the body's relaxation/tension level and gives both the patient and the therapist invaluable information regarding levels of physical and emotional trauma.
Biofeedback offers a direct scientific perspective of the mind-body connection. People begin to experientially realize the profound affect that their mind has on their body and the way they "feel". Patients suffering from everything from addictions to physical pain to emotional trauma begin to realize that they can psychologically (mentally) learn to control their physiology (body). This is a very liberating and powerful epiphany, as well as an invaluable tool in a variety of health treatment modalities including physical pain and emotional trauma.
