The main causes of coughing when agitated are emotional factors, chronic pharyngitis and bronchial asthma. 1. Emotional factors: when a person is overly excited by anger, joy and other emotions, it can lead to an increase in central nervous system excitability, which may cause the cough reflex center to be abnormally active, thus leading to coughing. 2. Chronic pharyngitis: the pharyngeal mucosa of patients with chronic pharyngitis has been infected by pathogens for a long time and is in a state of high reaction. When a person is agitated, the respiratory rate will be accelerated, the speed of airflow in and out of the throat will be increased, and the stimulation of the mucous membrane of the throat will be enhanced accordingly, which will then cause coughing. 3. Bronchial asthma: bronchial asthma patients in the excitement, can cause bronchial spasm, induced asthma attack, the patient will cough frequently. If you cough when you are excited, you should go to the hospital in time to receive treatment, so as to avoid adverse consequences.
