What is the relationship between cold air and cough in modern medicine?

The cough caused by inhaling cold air may be due to the inflammatory changes of bronchial mucositis, which affect the ventilation and ventilation function of lung function. Bronchial asthma generally encounters allergens such as pollen, grass powder and milk, including cold air, and it will cough. If you breathe in cold air, you will have symptoms of coughing. You can go to the hospital to check the lung function in time and find out the reason. The symptoms of cough mainly appear in winter and will be relieved after warm spring. Avoid catching cold in daily life and prevent colds.
