why is my child coughing only at night
Nocturnal asthma is another common cause of nighttime coughing in children. Coughing occurs at night primarily because of changes in the airways that occur with sleep. An asthmatic cough tends to be a dry, hacking cough and is frequently accompanied by wheezing.
Postnasal drip occurs when the nose produces excessive amounts of mucus. The mucus may drip out the nose during the day, but when the child lies down at night, mucus collects in the back of the throat, triggering a cough. Postnasal drip syndrome is a common cause of nighttime coughing in children.
