Chronic stress can have dramatic effects on your body.  This may include elevated blood pressure, increased body temperature and disruption of brain function.  By promoting a more effective mental and physical response to stress, biofeedback aims to help you control body processes like your heart rate and blood pressure.
Biofeedback is a type of therapy that uses sensors attached to your body to measure key body functions.  Beiofeedback is intended to help you learn more about how your body works.  This information may help you to develop better control over certain body functions and address health concerns.
