A
When confronted with a stressor, the body's flight-or-fight response is stimulated. As a result, the body releases epinephrine, speeds up metabolism, and increases heart and respiratory rate. It has been found that relaxation techniques offer a way for a person to reduce the flight-or-fight response, returning the body to a normal physiological state. This normal physiological state leads to improved immune system functioning.
