Medicine believes that the back can improve human immunity, especially suitable for the health care of middle-aged and elderly people. Its principle is that there are abundant spinal nerves and many important positions on both sides of the human back spine, which are widely related to human internal organs. The back can stimulate the tissues and parts of the back, and then promote local and even systemic blood circulation through the conduction of the nervous system and meridians, and enhance the functions of endocrine and nervous system.

Therefore, it can tonify the yang of the whole body, balance yin and yang, strengthen the body resistance and eliminate pathogens, harmonize qi and blood, dredge meridians and improve the function of viscera, thus greatly improving the immunity and disease resistance of the body.
