How to cough when it's cold?

Cough is usually a normal rejection caused by external stimuli. Cough easily occurs in spring or autumn, or when the weather is cold. One is to reduce the chance of going out, and the other is to wear a mask when going out, which can still achieve good results in preventing this cough.

Antibiotics should be used to control infection, and drugs for resolving phlegm and relieving cough or drugs for dilating trachea should be used. It may be caused by bronchial asthma, which is an autoimmune disease. It is necessary to take anti-immunity, use adrenocortical hormone or immunosuppressant, or use drugs to inhibit the release of inflammatory mediators, and use drugs to dilate trachea to relieve symptoms.
