Allergic cough is a cough caused by allergens stimulating human respiratory tract, which is characterized by paroxysmal dry cough after contact with allergens, less sputum, and mild or no cough after leaving allergens. If you are exposed to allergens or strong allergens for a long time, it will also cause allergic pneumonia.

Common allergens causing allergic cough can be divided into endogenous and exogenous categories. Endogenous allergens such as Ascaris lumbricoides and hookworm larvae can cause allergic cough when they migrate in trachea and lungs. Exogenous allergens include dust, animal fur, feathers, paint, pollen, chemical fiber fabrics, drugs and so on. Your daughter has a light cough during the day, a heavy cough at night and a heavier cough in the middle of the night. Therefore, we should consider the sensitive environment for children to sleep, such as new chemical fiber bedding, indoor flowers, pets, newly renovated houses or new furniture.

If allergic cough only uses anti-allergic drugs, it can only temporarily relieve symptoms, but not the cause. For example, children are allergic to dog dander. Although they take anti-allergic drugs, they still touch the dog many times a day and cough will not stop. Therefore, it is suggested that you look for allergens, supplement anti-allergic probiotics and improve your allergic constitution. As long as your child's allergic constitution improves, it will heal itself when he grows up.
