Step-by-step explanation:
Sleep apnea is a chronic disorder characterized by the cessation of breathing during sleep. It can occur in both children and adults. Sleep apnea episodes can last for several seconds or minutes. There are two types of sleep apnea: obstructive sleep apnea and central sleep apnea. Obstructive sleep apnea is caused by an obstruction in the airway during sleep, while central sleep apnea is caused by a failure of the brain to send the appropriate signals to the muscles that control breathing. Patients with sleep apnea may experience symptoms such as fatigue, irritability, memory problems, and morning headaches. They may also have a dry throat in the morning due to excessive snoring.
