Video: What happens during obstructive sleep apnea? When you breathe, air travels down your throat, through your windpipe and into your lungs. The narrowest part of that pathway is in the back of your throat. When you're awake, muscles keep that pathway relatively wide open. But when you sleep, those muscles relax, allowing the opening to narrow. The air passing through this narrowed opening may cause the throat to vibrate. That causes snoring, which many people experience. But in some people, the throat closes so much that enough air can't get through to the lungs. When this happens, the brain sends an alarm to open the airway. Most often this is associated with a brief arousal from sleep. The brain quickly re-activates the muscles that hold the throat open, air gets through again, and the brain goes back to sleep. This disorder is called obstructive sleep apnea.

Will my insomnia during pregnancy harm my baby? But relax — your baby sleeps even when you're wide awake. And it's unlikely your baby is bothered by any sounds that may be keeping you awake. Layers of skin and muscle, as well as amniotic fluid and the sound of your heartbeat, insulate your baby from outside noise and routine movement. Your baby's health is at risk, however, if your insomnia during pregnancy affects your ability to function. If you fall asleep while driving, or exhaustion leads you to stumble or fall, your baby could pay the price.

During sleep, we usually pass through five phases of sleep: stages 1, 2, 3, 4, and REM (rapid eye movement) sleep. These stages progress in a cycle from stage 1 to REM sleep, then the cycle starts over again with stage 1 (see figure 1 ).
