Biofeedback training uses simple electronic devices to measure and report information about
a person’s biological system. Biofeedback training can improve health by teaching a
person to consciously regulate bodily functions that are normally unconscious, such as heart
rate, breathing, and blood pressure. Biofeedback training is particularly useful in treating
health conditions where psychological factors are present. This form of healthcare is used for
pain relief, stress reduction, insomnia, headache treatment, and muscle injuries.
