Biofeedback therapy involves training individuals to control physiological processes such as muscle tension, blood pressure, or heart rate.  Biofeedback is particularly effective at treating conditions brought on by severe stress.  When a person is stressed, their internal processes (such as blood pressure) can become irregular.  Therefore, biofeedback therapy teaches individuals certain relaxation and mental exercises which can alleviate their symptoms of anxiety.  For someone who struggles with high blood pressure or anxiety, the use of biofeedback therapy can be the perfect form of treatment to decrease these symptoms.
