What reason is cough day and night

summary

I had a cold and fever a month ago. After the fever subsided, other symptoms gradually improved, but my throat was dry and itchy all the time. I coughed and had a small amount of phlegm. It was OK during the day, especially at night. The more late in the night, the more serious my cough became. Not only did I not sleep well, but also all the people in the same dormitory were affected to have a bad rest. This symptom lasted for half a month Let's have a look at the following.

What reason is cough day and night

First, cough is a reflex action of the human body to protect the body. Its main function is to remove the secretions of the respiratory tract. Therefore, cough is the main manifestation of diseases in the respiratory system. If the cough is long-term and repeated, especially aggravated at night, it may be suffering from chronic bronchitis.

Second, there are two main causes of chronic bronchitis: one is external causes, such as virus infection, cold air or dust stimulation to the upper respiratory tract, including allergic reactions; the other is internal causes, including autonomic nerve dysfunction, respiratory immune and defense dysfunction, as well as genetic factors.

Third: after suffering from chronic bronchitis, we must first control the infection, sputum must be discharged, and the air in the living environment must be fresh and moist. Do not smoke, usually to strengthen exercise, improve the body's resistance, when the weather turns cold, to add clothing in time to avoid cold.
