Biofeedback is a tool used by NDs to help patients avoid the long-term harm stress can cause the body. It can also be used to manage pain, lower blood pressure, and reduce anxiety. It works by educating you of your voluntary and involuntary physiological response to stressors through observation and special programs. The most common responses to stress are changes in breath rate, blood pressure, heart rate, temperature, and muscle tension. When you are aware, you can stop the responses before they spiral out of control. This will increase your physical and emotional health and the well-being of those affected by you.
