Young must sleep well? No! There are many children who do not sleep well. They snore incessantly, have difficulty breathing, have night sweats, are reluctant to be covered, are restless, drool, grind their teeth, and sometimes have symptoms of upper airway obstruction, labored breathing, and collapse of the chest when inhaling. For fear of accidents while the child is asleep, parents have to stay with and watch over the child all night. In fact, these are the typical manifestations of sleep disordered breathing disease. Compared with the symptoms of adults, children’s sleep apnea also has some obvious differences: adult patients are often sleepy and unfocused during the day, while children have an abnormal increase in activity, accompanied by speech defects, reduced appetite and swallowing difficulties, and often some non-specific behavioral difficulties, such as abnormal shyness, delayed development, rebellion and aggressive behavior. Children who are attending school are also prone to poor concentration in class and decreased academic performance. Sleep apnea in children can have a significant impact on the child. In addition to behavioral difficulties and daytime sleepiness due to poor sleep, it can also lead to hypertension, pulmonary heart disease, congestive heart failure and even death. Some children will also suffer from physical growth and development and mental health as a result.
