Sleep Apnea is a sleep disorder afflicting tens of millions of people worldwide, which is characterized by shallow breathing and or pauses in breathing, and often snoring. Each pause in breathing can last between several seconds to several minutes and Sleep Apnea by definition requires five such episodes per hour. The pause in breathing allows carbon dioxide levels to build up in the bloodstream, signaling the brain to wake up the person to let them breathe in air. This restores normal oxygen levels and the person can fall asleep again, if they are not too awake to do so. It is common for those with sleep apnea to snore.
