Biofeedback is a therapeutic technique intended to help a client to control and manipulate their bodily functions (like heart rate and blood pressure). Biofeedback is based on the belief that a person can utilize the power of the mind to become more aware of what is happening inside the body and can use that awareness to achieve a greater control over their health. During a biofeedback session, the client is connected to sensors that send information about what is happening in the body.
This information helps the client to concentrate on trying to make changes in the body, like slowing breathing or relaxing a muscle. Biofeedback is used for relaxation, to alleviate stress and anxiety and for a number of physical conditions (like migraines, high blood pressure, asthma, and chronic pain).
