Medically, coughing is a necessary reflex that protects the body. When something invades the airways, the respiratory system will stimulate the child to cough. During daily life, there are many factors that can enter the airways, causing the child to cough to expel foreign objects.

Prolonged allergic cough is a fairly common condition, especially for people living in hot, humid climates with lots of rain. Treatment of allergic cough requires guidance and prescription from a doctor, patients should not take medicine on their own.
