What is REM rebound?

When a person has been deprived of REM sleep for long enough they will not cycle through sleep patterns as a well rested person would. These REM deprived patients will enter REM sleep much more rapidly and will spend more time in REM sleep over the course of the night as their body attempts to "catch up" for the lost REM. This expedited process of entering REM is called REM rebound.

Does REM occur in sleep panic patients?

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.


Is rem sleep deep?

3/13/2012 jhh: REM sleep is NOT deep sleep. In fact, it is the lightest stage of sleep. In order from awake to deep sleep: AWAKE, REM, LIGHT, DEEP. Deep sleep and REM sleep are the most important stages though. Light sleep doesn't do much for you. Deep replenishes your body, while REM replenishes your mind. Older answer (not accurate): Yes. It is the deeper form of sleep that we experience during our sleep cycle, rem sleep is where dreaming occurs But not the deepest sleep, which would be delta. That's where, unless your a mother and hear your baby cry, you are oblivious to your environment.
