With the arrival of autumn and winter, it is easy to develop chronic bronchitis. Reasonable exercise can help improve the body’s resistance and prevent the onset of chronic bronchitis. In autumn and winter, it is necessary to pay more attention to respiratory health care. In this issue, we recommend some targeted exercises for bronchitis patients. Exercise can relieve adverse symptoms Chronic bronchitis is a common disease, especially in the elderly, with peak incidence in the fall and winter. Chronic irritation from dust, air pollution, irritating fumes, and long-term smoking are the main causes; cold weather and allergies are also triggers for the onset of the disease; weakened body resistance and reduced local defense of the respiratory tract are the internal causes of chronic bronchitis. The main symptoms are cough, sputum, wheezing or shortness of breath, especially in the early morning or at night, and increased sputum volume. When it is complicated by emphysema, in addition to symptoms such as cough, sputum and wheezing, dyspnea gradually appears. Exercise therapy is very helpful in improving lung function and is suitable for various degrees of chronic bronchitis. Through exercise therapy, the body’s fitness can be strengthened, the body’s immunity can be improved, the metabolism can be improved, and the adaptability of the body to physical activities can be enhanced. On the basis of controlling inflammation and spasm, reducing the degree of airway obstruction can effectively improve lung ventilation and gas exchange between blood and alveoli, thus relieving shortness of breath and shortness of breath symptoms. At the same time, exercise can also eliminate or reduce the causes of bronchial irritation, promote the discharge of phlegm in the trachea, reduce bronchial inflammation, and enhance cardiopulmonary function. Learn the correct way of breathing First of all, unreasonable breathing should be corrected. In emphysema, the diaphragm is depressed and restricted, and the thorax is in a relative inspiratory state. To compensate for the lack of breathing volume, patients often use the auxiliary respiratory muscles during inspiration, or even wrongly contract the expiratory muscles – the abdominal muscles – during inspiration. As a result, breathing becomes shallow and fast, especially laborious, and gas exchange is inadequate, thus further aggravating the symptoms of shortness of breath. Abdominal breathing This type of breathing means that during breathing, the exhalation time is prolonged by consciously changing the tension of the abdominal muscles and the pressure in the abdominal cavity. That is, during inhalation, the abdominal muscles relax and the abdomen bulge outward, so that the diaphragm sinks and expands the volume of the chest cavity; during exhalation, the abdominal muscles contract and the abdomen sinks inward, so that the diaphragm lifts up and squeezes the lungs to expel the air from the lungs. Contracted mouth breathing Inhale with the nose, the air is adsorbed, filtered, moistened and warmed by the nasal cavity, which can reduce the stimulation of the trachea. Contracting the lips into a flute shape so that the gas is exhaled slowly through the narrowed mouth shape can delay the occlusion of the bronchial walls. Whole-body respiratory gymnastics On the basis of abdominal breathing exercises, whole-body respiratory gymnastics can be performed, that is, breathing and chest expansion, bending, squatting and other movements combined together, according to the main points of abdominal breathing exercises. Auxiliary therapy selected aerobic exercise Aerobic exercise can effectively improve cardiorespiratory function. Generally speaking, patients with simple chronic bronchitis have basically normal lung function and tolerate exercise better during the stabilization period of the disease, so they have more freedom to choose the way of exercise, including swimming and ball games, etc. The amount of exercise can be adjusted mainly by individual subjective symptoms. Patients with asthmatic bronchitis have some degree of impaired lung function and are less tolerant of strenuous activities. Exercise should be selected according to their physical condition, with the amount of exercise ranging from small to large and the duration of exercise ranging from short to long, to ensure that there are no significant episodes of shortness of breath after exercise. Walking is recommended for weaker patients. Walking is a whole-body exercise. The movement of the legs promotes the rhythmic contraction of the abdominal muscles, and the swing of the arms increases pulmonary ventilation and improves lung function.
