What causes cough in summer?

Cough is a kind of protective respiratory reflex, which is a physiological reflex caused by the impulse to enter the cough center of medulla oblongata after the respiratory tract is stimulated (such as inflammation, foreign body, etc.). It can discharge respiratory secretions or foreign bodies and protect the cleanliness and patency of the respiratory tract. Therefore, coughing is generally a beneficial action, and it is sometimes seen in healthy people. Under normal circumstances, a slight and infrequent cough can be relieved naturally as long as sputum or foreign bodies are discharged, and no antitussive drugs are needed. However, for those with severe dry cough without phlegm, or those with severe cough with excessive phlegm, it not only increases the pain of patients, affects rest and sleep, increases physical exertion, and even promotes the development of diseases, resulting in other complications. At this time, the disadvantages outweigh the advantages. Therefore, antitussive drugs should be used appropriately to relieve cough.

I suggest you see a doctor as soon as possible. Bronchitis, pneumonia and encephalitis are common diseases of children in summer, and the first two symptoms are cough.

I hope my answer is helpful to you.
