Biofeedback is a behavioral intervention technology based on psychophysiology, which uses various electronic devices to collect the physiological activities of individuals in real time and provides them to themselves through various ways, so that people can actively change their own physiological changes when they perceive the changes in some physiological functions of their own, and consciously control the physiological functions of various aspects of the autonomic nervous system within a fixed range. It can play a role in improving physical health status, preventing and treating some somatic diseases 1. Studies have shown that biofeedback relaxation training can make the training subjects learn to regulate their own physiological functions and psychological activities, improve negative emotional states such as depression and anxiety by regulating the body function, and can also be used to assist in the treatment of other clinical diseases. As a new psychological intervention, biofeedback relaxation training has great development potential and can be better applied to the prevention and treatment of physical and mental diseases in the general population in the future.
