The theory that individuals can become aware of, and exert some control over, involuntary bodily functions, such as heart rate, blood pressure and muscle tension, is at the heart of the technique of biofeedback. Biofeedback is not a therapy in itself, but a means of monitoring your bodily functions through the use of other therapies such as meditation, autogenic training and relaxation techniques.

To learn to modify involuntary bodily functions, you need first to be given and then to monitor signals relating to the part of your body you are trying to control. These feedback signals, such as electronic responses from your muscles, are recorded on a biofeedback machine. Although the technique dates back to the 1930s, the term biofeedback was coined in 1969.

It was initially used to describe procedures that trained research NLS Analyzer subjects to alter their brain activity, muscle tension, heart rate, movement in the gut, stomach acidity, and other bodily functions that are normally controlled by the body’s autonomic nervous system. By hooking yourself up to a biofeedback device and altering subtle bodily functions, you can reduce your muscle tension, thereby alleviating all stress related conditions, such as headaches, migraine, anxiety, insomnia, high blood pressure, irritable bowel syndrome and asthma and allergies.
