Traditional Chinese medicine believes that the back is yang and the abdomen is yin, and the yang meridian of the human body is basically distributed in the back, so the spine of the back is the main meridian of yang. Du meridian is related to the Six Yang Meridians, so it is called "the sea of Yang Meridians", so it is in charge of the whole body of Yang, and the movement of Yang is related to the spine. Therefore, the warmth and coldness of the back is closely related to the function of viscera. "Four Essentials of Caution in Health Care" mentioned: "The back is connected with the five internal organs, and the back is always warm. If it is warm, the lungs will not be hurt. " "On the News of Taking Pictures in Spring" also said: "Don't get cold on your back, it will hurt your lungs and your nose and cough." So the cold invades the human body, and the back bears the brunt. When the back is cold, there will be problems such as backache, muscle twitching, etc., which will easily lead to discomfort of joints and internal organs of lower limbs and form diseases. Especially for people suffering from rheumatic pain, bronchitis, asthma, gastric and duodenal ulcers and cardiovascular diseases, it is very important to keep your back warm. Even in summer, when the weather is hot and sweaty, it is easy to cause wind-cold attack and diseases. Therefore, back health is very important, and keeping warm is the primary task.
Stimulating meridians and regulating qi and blood is often difficult to get enough attention in the back because it is behind. However, in the concept of health preservation in past dynasties, the back is very important. For example, on both sides of the spine are the bladder meridian of Foot Sun, which runs through the whole body, and the back Shu points of all zang-fu organs are located in the bladder meridian of the back. Stimulating these acupoints can dredge meridians and qi and blood, tonify Yang Qi, harmonize qi and blood, and restore the function of viscera. Modern medicine has made it clear that the posterior spine is the place and channel where the brain and spinal cord lead to various organs and tissues of the body and send out nerve roots. On both sides of the spine, there are some autonomic ganglia, which can regulate internal organs. Therefore, through health care methods, scientifically and appropriately stimulating acupuncture points and meridians on the back can play a role in treating diseases and health care.
