Biofeedback is a complementary and alternative medicine technique in which you learn to control bodily functions, such as your heart rate, using your mind. With biofeedback, you're connected to electrical sensors that help you measure and receive information (feedback) about your body (bio). The biofeedback sensors teach you how to make subtle changes in your body, such as relaxing certain muscles, to achieve the results you want, such as reducing pain.
In essence, biofeedback gives you the power to use your thoughts to control your body, often to help with a health condition or physical performance. Biofeedback is often used as a relaxation technique.
