Sleep apnea is a common sleep disorder characterized by repeated interruptions in breathing throughout the sleep cycle.These interruptions, called apneas, are caused by the collapse of soft tissue in the airway, which prevents oxygen from reaching the lungs. Weak muscles in the airway, a large tongue, obesity, and other factors may cause airway tissue to collapse and obstruct breathing.Sleep apnea disrupts the sleep cycle and can dramatically impact energy, mental performance, and long-term health. In some cases, if left untreated, sleep apnea can be fatal.
