There are many factors that can lead to this situation, mainly divided into two categories: pathological and non-pathological factors. Non-pathological factors: The first thing to consider is improper sleeping posture. Many children sleep in a crooked position and like to stir up the covers, which may cause lung discomfort and then coughing and heavy breathing if they sleep in an improper position. This can also lead to coughing in bed, as too much confinement can cause the air to become cloudy. Parents should keep the indoor air circulating and fresh to help their children relieve coughing symptoms. Pathological factors: There are many pathological factors that can cause a child to sleep with a cough, such as inflammation of the throat or a cold. Laryngitis is also common in children, and this often leads to coughing and wheezing, which needs to be treated actively. A child’s sleeping cough may be caused by a disease or by the environment. Whatever the cause, as long as it is improved and controlled in time, you can quickly get rid of the cough.
