What is Biofeedback?
Biofeedback is one method of learning to
achieve relaxation, control stress responses, or modify the
body's reactions through the use of monitoring equipment that
provides information from the body which would normally not be
available. This method is based upon the principle first
advanced in the early 1960s that the autonomic nervous system
(the part we don't consciously use) is trainable. For example,
instruments can be used to measure heart rate, blood pressure,
brain activity, stomach acidity, muscle tension, or other
parameters while persons experiment with postural changes,
breathing techniques, or thinking patterns. By receiving this
feedback, one can learn to identify the processes that achieve
the desired result, such as reduction in heart rate and blood
pressure. Biofeedback is used by many practitioners for a
variety of psychological and physical conditions.
