heart rate
Biofeedback . Learn how to manage your heart rate, muscle tension, and blood pressure when stress hits. Biofeedback gives you information about how your body reacts when you try to relax. Sensors are placed on your body that call out changes in everything from your brain-wave pattern to your muscle tone. Working with a biofeedback therapist, you can start to take control of the signals by changing how your body reacts to the sensor.
