Let's first look at the principle of qigong. Qigong is an exercise method for health preservation, disease prevention, health care and physical fitness, which is suitable for people of any physique to practice. When practicing qigong, you should pay attention to deep breathing. Deep and long abdominal breathing can increase the lifting range of diaphragm by 3 ~ 4 times, the intra-abdominal pressure rises and falls rhythmically, and the abdominal muscles participate in breathing. This is a form of "internal massage" that other sports can't do. It has a good effect on eliminating the blood in the inner wall of abdominal cavity, increasing gastrointestinal peristalsis, promoting the circulation of blood and lymph in abdominal cavity and promoting the digestion and absorption of food, so it also has a good therapeutic effect on some chronic diseases. Deep breathing and qigong breathing are similar in physical strength.
When people take a deep breath, the range of motion of the diaphragm increases exponentially, which is beneficial to effectively massage the stomach, promote blood circulation, and enhance digestion and breathing functions, so deep breathing is beneficial to health. Deep breathing has a good effect on hepatitis, dyspepsia, gastroptosis and habitual constipation.
Deep breathing can compress the lungs, promote the great blood vessels in the heart and chest, improve blood circulation and promote metabolism.
Deep breathing can also increase the chest volume, which is conducive to the expansion of the heart and promote the physiological function of the respiratory system.
Although deep breathing is good for your health, it should be done in a timely and moderate manner, and you must not be greedy for "one battle is over" or "one day is frozen for ten days", but insist on doing it reasonably and moderately. In addition, when suffering from some respiratory diseases, such as active tuberculosis, pulmonary hemorrhage, pneumonia and so on. It is generally not advisable to take a deep breath.
