Sleep apnea is a disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. These pauses can last from a few seconds to minutes. Typically, normal breathing then starts again, sometimes with a loud snort or choking sound. Sleep apnea usually is a chronic, ongoing condition that disrupts your sleep. When your breathing pauses or becomes shallow, you’ll often move out of deep sleep and into light sleep. As a result, the quality of your sleep is poor, which makes you tired during the day.
