Biofeedback is the process of learning to influence involuntary body
processes in order to receive physiological data from an electronic device that
continuously monitors specific physiological parameters. It is a method of assessing
how people react to physical, emotional, mental, and spiritual stresses in their lives.
Stressed-out bodies are more prone to physical discomfort and even illness. When the
body receives new information about its status, it responds by making healthy
adjustments to reduce stress and tension. Biofeedback relies on electrical measurements
taken from the front of the body (frontal cortex). When this information is presented to
the patient, he attempts to consciously change their internal reactions in order to change
the electrical results. The chapter discusses biofeedback technology and its applications
in psychology and other treatments.
