Some people will have coughing symptoms, but if it is a mild cough, and no obvious clinical symptoms, this is a physiological change. 2. Airway hyperresponsiveness disease: such as cough variant asthma or allergic cough, these patients due to airway hyperresponsiveness, encountering cool air stimulation will lead to bronchospasm, the patient therefore have coughing symptoms occur. 3. Chronic bronchitis: this patient’s trachea-bronchus often have chronic inflammation, in the cool wind stimulation will aggravate the cough symptoms. See cool wind cough may have other reasons, such as not relieve the need to go to the hospital as soon as possible, by the doctor to clarify the cause of the disease, and standardize the treatment, so as not to delay the condition.
