Hypertension is the culprit of cardiovascular and cerebrovascular diseases, is a common clinical disease, and is one of the diseases that seriously endanger human health. The prevalence of hypertension in China is growing at an average rate of 3.5 million people per year, and the high rate of disability and death from hypertension has caused a heavy economic burden to society and families. Therefore, it is important to carry out the prevention of hypertension. Health education and promotion should be strengthened to popularize the knowledge of hypertension, community-based and sports-oriented, especially the popularization and application of taijiquan. The basic taijiquan method: one of the greatest advantages of taijiquan is that it can be practiced quickly and slowly, rigidly and softly, easily and casually, very subtle, but also to open up the frame tiger, majestic. It is because Taijiquan can be flexible to choose the degree of difficulty, ease and intensity of movement (unlike other types of boxing that can only be fast and not slow), so people of all ages, physiques and genders can learn to practice Taijiquan, and they can choose the type, practice and difficulty of Taijiquan according to their own physical qualities and physical state. For example, the left and right wild horse mane, left and right range bird’s tail, left and right backward scrolling porpoise, in situ cloud hand, collection potential, etc., all have a very good effect on the pressure. Taijiquan and the balance of yin and yang: Taijiquan is guided by the balance of yin and yang and the change of reality and emptiness, which is the same principle as the theory of yin and yang in Chinese medicine. Taijiquan requires both arms to run at the same time, and the two arms are united as a whole, with yin and yang transforming into each other. Taijiquan regulates the balance of yin and yang in the human body through the yin and yang changes in the stances, so that the yin and yang of the human body are in the best state of balance and coordination, thus making the internal organs, meridians, qi and blood coordinated and balanced, which is in line with the “holistic diagnosis and treatment” and “evidence-based treatment” of Chinese medicine, namely The concept of Yin and Yang, Yin and Yang balance, Yin and Yang transformation, in order to enhance the internal harmony and order of the human body system to achieve the health care function, so as to achieve the purpose of disease prevention and treatment, strengthening the body. The mechanism of taijiquan to prevent hypertension: emotional tension is one of the causes of primary hypertension. When playing taijiquan, the whole body should be relaxed, calm and relaxed, with the intention to lead the gas, the intention to follow the body, continuous as the flow of water, the whole set of no special force and too fierce, too fast action. Therefore, it can relax the tense nerves and improve the regulation function of the central nervous system, so that the endocrine imbalance and the imbalance of the plant nerve function can be adjusted. The central nerve of the brain is subconsciously practicing the movements under the requirement of “relaxation and stillness”, the brain is in a state of protective inhibition, the sympathetic nerve activity is reduced, so that the active substances in the blood such as norepinephrine and epinephrine that cause vasoconstriction are reduced, and the active substances in the blood such as histamine and kinin that cause vasodilation are increased, and the reflexes of the blood vessel wall caused by the relaxation of the muscles in the whole body are increased. In collaboration with the reflexive relaxation of the blood vessel wall caused by the relaxation of the muscles, the capillaries are maximally dilated and the microcirculation is enhanced, thus reducing the total peripheral resistance of the blood vessels and causing the blood pressure to drop. Taijiquan’s intention to induce qi enables qi and blood to flow smoothly through the body’s meridians, calms yin and yang, and brings into play its two-way regulatory effect of “suppressing hyperactivity and helping deficiency”, which is conducive to maintaining a normal and stable blood pressure. Taijiquan is a dynamic exercise that makes the muscles of the whole body alternate between contraction and relaxation, which is harmonious and natural, loose and slow, and the whole body muscle fibers repeatedly contract and stretch, which plays a natural “massage” effect on the smooth muscle of the blood vessels, prompting the blood vessels to contract and stretch rhythmically, gradually flushing and eliminating the cholesterol deposits in the blood vessel walls, and improving the atherogenic properties of the arterial blood vessel walls. The atherosclerotic lesions of the arterial walls are improved. It is recommended that patients should strengthen the practice of taijiquan, generally hypertension is accompanied by heart disease, most of the causes of this disease have mental factors involved. Older friends should practice both gongfu and gongde, that is, to cultivate the mind, cultivate the emotions, to be open-minded, open-minded and optimistic.
