Answer:
Biofeedback.
Step-by-step explanation:
Biofeedback is the process by which a person can maintain or regulate his/her body needs and stress levels. This process teaches people to recognize the signs and levels of stress and anxiety in a person's body.
Medical practices of such a process involve the use of sensors that will track and record the body's physiological responses to certain elements. This will enable the person to learn to control some of the body functions, like maintaining your heart rate, tension, or even temperature of the body.
So, learning to control her physical processes with her mind through the information provided by the doctor enables Tricia to regulate and maintain her physiological state.
Thus, the correct answer is biofeedback.
