The so-called “abdominal breathing”, that is, the use of the abdomen to assist breathing action. Ming Dynasty health practitioner Leng Qian authored the “key to the cultivation of age” has: “a suction will be raised, gas long return to the umbilicus, a mention will be swallowed, water and fire see each other.” Which contains the abdominal breathing of the key to health. The correct and regular abdominal breathing, why can play a role in prolonging life, fitness and disease prevention? Chinese medicine believes that the abdomen in the middle of the human body, is the convergence of many important meridians, the spleen and stomach is the body’s back of the day, the origin of the camp and blood, the body’s organs, limbs and bones of nutrition, are dependent on the stomach to receive the water and grain essence to feed. The spleen and stomach are in the middle jiao, and are the hub of the body’s qi flow. The normal function of the spleen and stomach, the clear rise and fall of turbidity, normal gasification, so that the body to maintain the relative balance of yin and Yang qi and blood. Abdominal breathing, with the ups and downs of the abdominal muscles, strengthen the flow of qi and blood, so that the body is in the best state of relaxation and stillness, but also the best state of the flow of qi, very beneficial to physical and mental health. Modern medical research believes that people do abdominal breathing, because the abdominal muscle tension and relaxation occurs alternately, so that the local muscle capillaries also alternate contraction and diastole, which can promote blood circulation, expand the supply of oxygen, accelerate the excretion of metabolic products of the body, the whole body organs and tissues can play a role in adjusting and promoting. In addition, the contraction and relaxation of the abdominal muscles is also a good abdominal massage. This massage can promote gastrointestinal movement, improve digestive function, and favor the body’s digestion and absorption of nutrients. The abdominal muscle is also the power muscle of defecation, the contraction of the abdominal muscle is conducive to defecation, so the abdominal breathing exercise is conducive to the prevention and control of habitual constipation. Medical research shows that abdominal breathing can increase the range of motion of the diaphragm, and the movement of the diaphragm directly affects the ventilation of the lungs, so regular practice of abdominal breathing can increase lung capacity and help improve the ventilation function of the elderly and patients with chronic emphysema. For every 1 cm drop in the diaphragm, lung ventilation can increase by 300 to 350 ml; 3 months of abdominal breathing exercises can increase the range of diaphragm movement by 2 to 3 cm, and after six months of doing it consistently, it can increase by 4 cm. Therefore, the oxygen inhaled and carbon dioxide exhaled can be greatly increased, and lung function can be significantly improved, which has a direct rehabilitation effect on the ventilation disorder produced by emphysema in the elderly. According to the famous British biologist Ba Feng, the maximum life span of a human being is equivalent to 5-7 times the completion of the growth period. The human growth period is generally completed between the ages of 20 and 25, and by this reckoning, the maximum life expectancy of a human being should be between 100 and 175 years. Reality shows that cattle, horses and other animals can live to the natural life span given by nature, while people can only live to about half of the natural life span. An important reason why humans do not live to their natural lifespan is the change in the way people breathe. All animals, except humans, use abdominal breathing. The advantage of abdominal breathing is that it can give full play to the function of lung cells and increase lung capacity. Since humans learned to walk, they have formed thoracic breathing, which greatly limits lung capacity, with only the upper half of the alveoli of the lungs at work. The alveoli of the middle and lower lung lobes, which account for 4/5 of all lungs, are idle for a long time, making it easy for the lung lobes to age, reduce elasticity, weaken respiratory function, affecting the body’s resistance to disease, susceptible to respiratory diseases, especially in the elderly, who are prone to pneumonia and other diseases when they feel wind and cold. The passage of time makes people old, inhale and exhale to rejuvenate. People want to have a long and healthy life, may often do abdominal breathing. The basic elements of abdominal breathing are: “thought dedicated, relaxed shoulders; first call after suction, suction drums and deflated; call when by the mouth, suction by the nose; call than suction long, not hard.” Specific exercise method is: supine, according to 5-6 times per minute, the abdominal wall rises when inhaling through the nose; exhale through the mouth when the abdominal wall sinks. To carry out abdominal breathing exercise to vary from person to person, according to the ability to do, the key is to inhale and exhale when the abdominal rumbling amplitude to the best of each person’s ability at the time, do not be too hasty; from shallow to deep, each time and daily exercise time at their own discretion, generally practice once a day in the morning and evening, each time 10 minutes can be.
