Biofeedback
Biofeedback is a method that turns certain physiological behaviors, like heart rate and blood pressure, into visible or audible signals for a person. For instance, they might use a machine that creates sounds or images to show if their heart rate is too high. Through training, the person learns to control and lower their heart rate by paying attention to these signals. It's a technique that helps individuals gain more awareness and control over certain bodily functions.
