The formation of COPD is closely related to many factors, especially smoking is the most dangerous factor. Therefore, the elderly must pay attention to quitting smoking, otherwise it will easily affect lung health and even lead to the formation of some lung diseases and cardiovascular diseases. At the same time, stay away from secondhand smoke and avoid exposure to secondhand smoke.

In the cold winter, the elderly should strengthen indoor thermal insulation to ensure that the indoor temperature is appropriate. Don't stay in a cold environment, or the stimulation of cold air may cause lung discomfort. The formation and aggravation of chronic obstructive pulmonary disease is related to respiratory virus and bacterial infection. Therefore, when going out, we should pay attention to ensuring indoor air circulation, ensuring that fresh air can enter the room, and be careful not to go to crowded places and wear masks.

The elderly can practice abdominal breathing and lip contraction breathing several times a day according to their physical condition. They can play Tai Ji Chuan and take a walk, which will help to adjust breathing frequency and improve lung function and exercise endurance. When the elderly have symptoms such as cough, expectoration and dyspnea, bronchodilators can be used reasonably under the guidance and advice of professional doctors. The decrease of cold tolerance in patients with chronic obstructive pulmonary disease can lead to repeated upper respiratory tract infections. Therefore, cold tolerance is also very important for patients with chronic obstructive pulmonary disease. Patients can exercise their cold tolerance by washing their faces with cold water in summer and insisting on outdoor activities every day.

Smoking is the main risk factor of chronic obstructive pulmonary disease. If the cause is not eliminated, it is difficult to achieve good results with drug treatment alone. Therefore, quitting smoking is a key measure to prevent the occurrence and development of COPD; Reduce the inhalation of occupational dust and chemical substances: workers exposed to occupational dust, such as coal mines, metal mines, cotton spinning industries, chemical industries and some mechanical processing industries, should do a good job in labor protection; Reduce indoor air pollution: try to avoid burning biofuels in poorly ventilated spaces, such as burning wood for cooking, building a fire indoors for heating, and passive smoking. Actively prevent and treat upper respiratory tract infection: get flu vaccine in autumn and winter, avoid crowded places, keep indoor air fresh, and actively treat upper respiratory tract infection;
