If a child’s cough is severe after strenuous exercise, the following measures should be taken: First, the child should be allowed to reduce the amount of activity, as strenuous exercise can stimulate the cough reflex and cause the cough to increase. Secondly, children should be given bronchodilator medication in a timely manner. The reason why children cough so severely after strenuous exercise is due to cough variant asthma, which occurs because of high airway sensitivity and intense coughing after a high airway reaction. Nebulized bronchodilators, such as terbutaline sulfate, can be used for rapid relief.
