When the weather is cold, I cough and have a lot of phlegm. What happened?

I think the first thing to understand is why you cough. For example, if someone smokes at home or has a pungent smell, it will cause a cough. This kind of temporary stimulation caused by the outside world, cough is a defensive reaction of the human body, which is used to expel foreign bodies and generally does not need treatment. If a persistent cough will cause a strong irritation to the throat, the secretory glands of the throat will increase secretion, produce sputum, and finally fall on the wet cough. If you have a cough with phlegm, you need to rely on some drugs to relieve and treat it, such as Mushutan oral liquid. By dissolving the thin sputum and promoting the discharge of sputum, the dirty things accumulated in the airway can be discharged.
