Clinically, there is no best exercise method for chronic obstructive pulmonary disease, and patients can choose the exercise method suitable for themselves according to their physical condition. Chronic Obstructive Pulmonary Disease (COPD) is a common chronic airway disease, the main symptom of which is dyspnea caused by persistent airflow limitation. Patients with COPD can perform breathing exercises to improve their lung function using abdominal breathing and lip-contraction breathing. Abdominal breathing is when the patient breathes deeply and slowly by consciously breathing through the abdomen, and lip-contraction breathing is when the patient exhales with the lips half-closed, i.e., when the lips are contracted, which is more similar to whistling. Patients with chronic obstructive pulmonary disease (COPD) should choose a small amount of exercise and a more gentle method of whole-body exercise. Walking is a kind of exercise method suitable for most patients, and the duration of each walk is suitable for not feeling tired. Walking for a long period of time is helpful in improving the lung function of patients. If diagnosed with chronic obstructive pulmonary disease (COPD), early and standardized treatment is recommended to reduce the adverse effects of the disease.
