"Biofeedback is a process that enables an individual to learn how to change physiological activity for the purposes of improving health and performance."

--- Opening sentence of consensus definitiion of Biofeedback by the Association for Applied Psychophysiology and Biofeedback (AAPB), Biofeedback Certification Institution of America (BCIA), and the International Society for Neurofeedback and Research (ISNR).

Biofeedback is the gradual and continuing process of becoming increasingly aware of various bodily functions and processes using scientific instruments that provide information on the activity of those same systems, with a goal of being able to alter our states, feelings, thoughts, emotions, and some physiological functions.

Some of the processes that can be learned to be controlled include various levels of brainwaves, relaxation, skin conductance (sweat gland activity), heart rate and pain management.

Biofeedback is often used used to improve health, relieve anxiety or depression, or increase performance, and the physiological changes often occur in conjunction with changes to thoughts, emotions, and behavior. The goal is to modify various behaviors and functions, and to carry the benefits into regular life without the use of extrernal biofeedback equipment.

In simple terms, biofeedback is a method for gaining control of our body processes to develop a propensity towards relaxation, assist in the relief from pain, and develop healthier, more balanced life patterns. Biofeedback provides information about ourselves with the use of external instruments. Using a thermometer to take our temperature is the most common application of biofeedback. Clinical biofeedback uses the same basic principles, using specialized instruments to monitor various physiological processes while they occur.

Some older systems display graphs on a computer monitors and sound basic audio tones that go up and down "reflect" changes as they occur in the person being measured. Biofeedback training familiarizes us with the activity in our various body systems so we may learn to control this activity to relieve stress and improve health. Trying to change physiological activity without biofeedback is like throwing darts in the dark - we can't see whether we are hitting the mark or not.

Unrelated, but very interesting is wondering how the Anasazi of Chaco Canyon may have used self-regulation. These "Ancestral Puebloans" were creative and excellent engineers for their time. You can read more about these people in the Amazon best seller "Anasazi of Chaco Canyon", a comprehensive book on the subject.

Biofeedback gives us the active feedback that lets us know when we are changing our physiology in the desired direction. Biofeedback itself is not a treatment. Instead, biofeedback training is a process of education and learning for specialized mind and body skills. Learning to recognize these responses and alter them is not unlike learning how to write or play the guitar - it requires practice. Through repetition, we become more familiar with our own unique patterns and responses to stress, and learn to control them rather than having them control us.
