Why does a child cough at night when he doesn't cough during the day?

Nowadays, many children cannot cough during the day but at night. The physiological reason for this phenomenon is that the air is too dry and the child’s sleeping position is improper. There are two main pathological reasons, the most common one is the common cold, and the other is upper airway cough syndrome.

Coughing is a very common phenomenon for children, but the causes of coughing are different and the symptoms vary greatly. For example, some children do not cough during the day, but the symptoms appear at night, which makes parents very worried. So why do children not cough during the day but cough at night?

1. Physiological reasons why children do not cough during the day but cough at night

1. The air is too dry

If the air in the room is too dry, it will also cause the child to cough when sleeping at night. Many people close the doors and windows at night because they are afraid that the baby will catch a cold. In this way, the indoor air will be very turbid and dry, which will cause the baby to cough.

2. Improper lying position

If a child does not cough during the day but coughs at night, it may be due to improper sleeping position. If this happens, it may cause poor breathing in the lungs or bronchial tubes, and then coughing symptoms. At this time, the baby will often be accompanied by breath holding, tears, etc., which requires sufficient attention.

2. Pathological reasons why children do not cough during the day but cough at night

1. Common Cold

Some babies who catch a cold will not cough during the day, but will cough constantly at night. This is because during the day, when they are standing, the inflammatory secretions caused by the infection will flow into the mouth or throat, so the coughing symptoms are very mild. But at night, when the baby lies flat to sleep, the inflammatory secretions will flow into the trachea. In order to eliminate these secretions, the patient will cough unconsciously.

2. Upper airway cough syndrome

Upper airway cough syndrome is also a common cause of this condition. Simply put, this disease is caused by the secretions in the baby's nasal cavity flowing into the back of the nose or the throat, causing coughing. For example, for babies with rhinitis, when sleeping at night, the secretions in the nose will flow into the throat, resulting in more obvious coughing symptoms. However, if the child's rhinitis symptoms are not serious and the secretions are not much, then basically there will be no coughing during the day.
