In winter, the water in the air will decrease and become very dry. The human body needs water, so it is easy to cough. In addition, because the weather is very cold, cold can easily lead to the decline of our body's resistance. If bacteria invade our throats, it will also cause us to cough, so many people can easily cough all day when winter comes. 2. Some chronic diseases are also easy to cause cough.
I have chronic pharyngitis myself. It's not serious, only mild, but in winter, because the weather is cold and dry, I cough easily. People like me have a weak voice, and they will cough when stimulated a little, but it is not serious and will not affect our daily life. In spring, the weather becomes mild and humid, and it is not easy to cough.
The above two reasons are the same. Once the weather becomes very good, for example, the water in the air increases and the air becomes a little milder, we are less likely to cough. For ordinary people, we generally don't cough. For people with some chronic diseases, but the situation is not serious, it is not easy to be stimulated.
In a word, I think I start coughing all day as soon as winter arrives, and I will get better gradually in spring. On the one hand, some people have some chronic diseases and cough when stimulated. On the other hand, the cold and dry weather led to the invasion of bacteria. Besides, they don't cough because of the mild weather in spring.
