Sleep apnea facts and statistics
Sleep apnea is a common sleep disorder in which breathing stops or gets shallow during sleep. It can be due to a mechanical problem in which the throat relaxes too much (obstructive sleep apnea) or a communication problem between the brain and the muscles that control breathing (central sleep apnea).
As the brain and body become oxygen deprived, normal sleep cycles are disturbed when you fall out of restorative deep sleep into light sleep. People with sleep apnea wake up feeling exhausted even though they have had a full night of sleep.
Obstructive sleep apnea (OSA)
Obstructive sleep apnea affects between 2-9% of adults in the United States (SleepFoundation.org)
