While you probably don’t have access to a machine that will measure and signal changes in your autonomic arousal, you can still try to control some of your autonomic responses yourself. lie down comfortably and imagine that you are on the beach or in a meadow. imagine the sun streaming down, warming your whole body. imagine that your stomach is becoming very warm with the sunlight. after a few minutes of imagining this, many people feel an actual warmth in their abdominal region. in fact, this is a popular technique in physical relaxation training that is often used for stress management. try it a few times. does your stomach feel warm? do you feel more relaxed? do you think this effect might be enhanced if a machine told you when your surface body temperature was increasing? if you know anyone who has had biofeedback, talk to them about their experiences. Would you consider biofeedback in preference to medication if you experienced severe headaches? Why or why not?
