Zhuangzi said, “Many people breathe with rest, while real people breathe with heel”, and practitioners pursue breathing with heel (this requires professional practice), while ordinary people breathe with rest. However, in clinical practice, I find that many people do not know how to breathe: I often find patients with their shoulders tilted up and their chins tilted down, breathing shallowly or sharply. So I would teach my patients to do deep breathing, and after obedient patients insisted on doing it, they found that their fatigue was relieved, their emotions were relaxed, and their symptoms such as chest tightness and panic, belching and bloating were relieved. In fact, deep breathing has many benefits: first, deep breathing can prevent and control respiratory diseases. Common respiratory diseases include chronic bronchitis, asthma, emphysema, etc.. The lungs of these patients are inelastic and dilated, affecting lung capacity. And deep breathing, can gradually increase the muscle contraction force, conducive to the effective expansion of the chest and lungs, enhance intercostal muscle vitality, can gradually restore its elasticity and lung capacity, so as to achieve the purpose of treatment and relief of the disease. Second, deep breathing can also prevent and control hypertension. This is a deep breathing method to lower blood pressure, the principle of which is that the human lungs have small pouches called alveoli, about 300 million. Under normal breathing conditions, only 80-90% of them can work adequately, and the remaining alveoli are in a wasted state. If deep breathing is used, the remaining alveoli can be made to work. When deep chest breathing is used, the alveoli located in the upper part of the lungs are opened; while in deep abdominal breathing, the alveoli in the lower part of the lungs are also opened. All the alveoli at work are producing prostaglandins, and by deep breathing also 80%-90% of the alveoli that were already at work produce more prostaglandins than they would otherwise. This allows more prostaglandins to enter the blood vessels, which results in vasodilation and lower blood pressure. Three times a day, morning, noon and night, for 10 minutes each time will have an effect. Again, deep breathing can help people reduce stress and relieve insomnia symptoms. When people take the initiative to adjust the depth and frequency of breathing, they can effectively relax the tense nerves and relieve anxiety. People with insomnia can also use breathing techniques to help them fall asleep. By lowering the rhythm of breathing and calming the breathing, insomnia symptoms can be reduced. Most importantly, deep breathing can promote a long and healthy life. As stated in the article “Breathing for Life”, “Controlled deep breathing exercises allow the brain to eliminate fatigue as soon as possible and can regulate the nervous system, making people relaxed and comfortable. The reason why deep breathing has such a great effect is that the amount of gas inhaled and exhaled by normal people each time is only 400ml-500ml, while doing the deepest breathing once can reach 3500ml for men and 2500ml for women, which is equivalent to 8 times of the usual inhalation, thus making life gain a lot of energy.” Deep breathing is easy to do and can be done at any time. The specific practice is: deep inhalation, so that the small stomach outward to make a strong bulge, after reaching the limit, gradually exhale gas, so that the small stomach inward to find the spine. Can be repeated, the more the merrier. Friends small gong method, big efficacy, insist on doing, wonderful endless. Of course, some people can not breathe well with the neck, chest and abdomen muscle fascia tension is related, it is best to find a professional doctor to consult the treatment to help loosen the relevant tension of the muscle fascia.
