Sleep apnea is a sleep disorder characterized by repetitive interruptions in breathing during sleep. These interruptions, known as apneas, can last from a few seconds to minutes and may occur multiple times an hour. The two primary types of sleep apnea are obstructive sleep apnea (OSA) and central sleep apnea (CSA). OSA is more common and occurs due to the physical blockage of the airway, while CSA is related to the brain's failure to signal the muscles to breathe.
