BIOFEEDBACK is a system of learning to control body functions, to influence the course of disease.
One can learn to increase or decrease heart rate at will, relax muscles, and alter brain rhythms.
The person is hooked to a monitoring machine that measures vital signs, translating them into visual or audio cues = FEEDBACK!!
A level is reached where there is no need for monitoring and the patient is able to affect these body processes when ever the need arises.
Used mostly for stress-related disorders, such as tension, migranes, high blood pressure, panic attacks: not meant to be the only treatment!
Some people will master it easily while others will not. Do not try too hard! The more at ease you are the better the response.
