How to cough when encountering cold air?

There are two main reasons for coughing when breathing cold air:

First of all, inflammation of respiratory tract can be inflammation of throat or inflammation of trachea or bronchus. When inflammation occurs, the nerve endings in the corresponding parts will be particularly sensitive and easily stimulated by airflow, especially cold air, which will induce muscle spasm and cause cough.

Second, allergic to cold air, this situation is often accompanied by skin cold urticaria.

If you cough when breathing cold air, you can observe it first and pay attention to strengthening exercise. When the weather is particularly cold, you need to wear a mask when you go out. If the symptoms are obvious, you should consider seeing a respiratory specialist, and if necessary, do lung CT or chest X-ray to rule out other lesions.

After suffering from cough variant asthma, it is possible to cough when encountering cold air. When the weather is too cold and the respiratory tract is stimulated by cold air, the bronchial smooth muscle will spasm, and the ventilation function will be damaged after bronchial contraction, causing cough. Patients need to go to a regular hospital to check bronchiectasis. If you are diagnosed with cough variant asthma, you need to inhale drugs for a long time to help the patient relieve cough. Patients taking montelukast sodium chewable tablets according to the doctor's advice before going to bed every day can effectively prevent coughing after falling asleep and reduce the frequency of asthma attacks.
