Modern medical theory holds that the physical stimulation formed by massage directly acts on the skin, nerves, lymph, blood vessels, muscles, tendons and joints of human body, which can effectively stimulate nerve endings, promote the circulation of blood and lymph, promote the metabolic process between tissues, maintain a stable and good relationship between organs and tissues, and gradually improve human functions. Traditional Chinese medicine believes that massage starts from the outside of the human body, and through benign stimulation, especially the stimulation of some acupoints, it can well stimulate the instinctive system of human self-regulation, so that the system disorder caused by various influences can be restored to the original balance state under the high self-regulation of the human body, thus achieving the purpose of eliminating diseases and keeping fit. Everyone may have had this experience. Sometimes your stomach will swell if you eat too much. When you feel uncomfortable, you will unconsciously touch your stomach with your hands, and the uncomfortable feeling may disappear in a short time. Sometimes if a posture is kept for a long time and the waist feels sore, you will unconsciously press and rub the waist with your hands, or beat the waist with your hands, which will also alleviate or eliminate the pain in the waist. These movements that we usually don't pay much attention to are vivid manifestations of the principle of massage fitness, which shows that massage is an instinct of human body system to protect and adjust itself when it is affected. This instinct has now developed into a complete system, which has played a huge role in people's treatment and fitness.
