There are 4 stages of sleep: Stage 1, Stage 2, Slow wave sleep, and REM. The stages occur in that order. Stage 1 occurs as you are falling asleep, and REM occurs last and contains the craziest dreams.

REM sleep is our restorative sleep. We all need it to restore our bodies. Patients with Sleep Apnea often have a decrease in the amount of REM sleep they get but still go into REM as does everyone. You may not achieve REM every time you sleep especially when you are just taking a short nap. There may be nights that a Sleep apnea patient does not achieve REM but that does NOT mean they never have REM sleep. When someone who has Sleep Apnea achieves Rem stage the apnea events increase because the tension and mucsles relax causing the obstruction in the airway to get worse. In turn the body reacts to the lack of air by gasping, choking, moving until the obstruction releases long enough for the person to breathe again. This often brings the person out of REM stage and into a lighter stage of sleep or wake stage. Therefore REM is often reduced. Around 20% of our total sleep time a night in REM is consider normal. Most sleep apnea patients' Rem is considerably less than this.
