What is sleep apnea?
Apnea (sleep apnea, or obstructive sleep apnea) is a serious disorder that causes interruptions of breathing (for at least 10 seconds) during sleep. While there are several types of sleep apnea, obstructive sleep apnea is the variant most people refer to. Depending on how often and for how long you stop breathing, sleep apnea can be classified as mild, moderate or severe. It is most common among men, affecting four percent of middle-aged men, but does affect women (about two percent of middle-aged women), and can occur at any age.
