The symptoms are somewhat similar to mine. The first time I got sick was when I was in college. Like your daughter, it was normal during the day but coughed in the early morning, especially in the hot and windless summer. In this situation, I saw many doctors, and many doctors could not tell me what the disease was. Finally, one doctor came to the conclusion that it was allergic asthma

The principle of traditional Chinese medicine is that the lungs detoxify at 3-5 am, so this I will have a bad cough for a while.

(9pm-11pm is the time for detoxification of the immune system (lymph nodes). During this time, you should be quiet or listen to music

11pm-1am is the time for liver detoxification.

The same goes for gallbladder detoxification at 1-3am and lung detoxification at 3-5am. The cough is most severe at this time,

Because the detoxification process has reached the lungs; do not use cough medicine to avoid inhibiting the elimination of waste products)

This situation does not require treatment, just stay asleep. Make sure the room is well ventilated, do not close the room, and open more windows for ventilation. If you pay attention to it at ordinary times, you will not have an attack.

In addition, if you are young, you should exercise more to increase your lung capacity and enhance your physical fitness
