Children coughing in the middle of the night and not coughing during the day, there are physiological reasons and pathological reasons, such as dry climate, variant asthma, etc., specifically analyzed as follows.
1. Physiological reasons: if the child is located in the environment is relatively dry, in the evening rest time intake of water is relatively small, resulting in dry throat caused by throat discomfort, which will appear in the middle of the night coughing.
2. Pathological causes
(1) If you suffer from sinusitis, when you lie down in your sleep, the nasal secretions will flow backward to the pharynx, which will stimulate your child to cough.
(2) If you suffer from cough variant asthma, the high tension of the vagus nerve at night, coupled with a decrease in the level of adrenaline, may lead to the contraction of bronchial smooth muscle, so that the airway becomes narrower, and the symptoms of coughing at night.
Children coughing in the middle of the night and not coughing during the day may also have other reasons, such as gastroesophageal reflux, etc., parents are advised to take their children to the hospital to do the relevant examination, according to the results of the symptomatic treatment.
