Proper breathing methods generally include shutting up and breathing, belly breathing, and deep, slow breathing. It should be practiced more often. Correct breathing methods in life are conducive to improving respiratory function and lung function, mainly the following three points: 1. Shut up and breathe, breathe through the nose, shut up and breathe is conducive to maintaining the moisture in the respiratory tract, to prevent excessive evaporation, to keep the respiratory tract moist. 2. Learn abdominal breathing, adults mostly chest breathing, but the amplitude of chest breathing is not as deep as abdominal breathing, abdominal breathing is more efficient than chest breathing; you can exercise the abdominal muscles, through abdominal exercises, so that the diaphragm down to increase the volume of exhalation, thereby increasing ventilation to improve respiratory function. 3. Try to do deep and slow breathing, is conducive to increasing ventilation, but also can reduce the consumption in the anatomical ventricular cavity of the ineffective ventricular cavity, increase the effective alveolar ventilation, at the same time will not increase the work of breathing, is conducive to reducing the body’s oxygen consumption. Patients with discomfort are advised to consult a specialist in a timely manner.
