REM sleep occurs a few times throughout a night's sleep and last from about 90-120 minutes each cycle. The longest period of REM sleep occurs closest to the morning.
No. I am a Martian and I get more than a Human. Pathetic weaklings, all you Earth-beings.

REM is during stage 3 and 4 where most of the dreaming occurs.
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.
True
rem sleep or paradoxical sleep
REM sleep is amazing sleep!
Rapid Eye Movement (REM) sleep is a normal stage of sleep characterized by the rapid movement of the eyes.REM sleep in adult humans typically occupies 20-25% of total sleep, about 90-120 minutes of a night's sleep. During a normal night of sleep, humans usually experience about four or five periods of REM sleep.
REM rebound involves the tendency for REM sleep to increase following REM sleep deprivation.
I don't really think anything causes REM sleep. REM stands for rapid eye movement, and it's one of the stages of sleep. I'm not certain, but I think it's the stage of sleep where your dreams are most vivid, meaning the deepest form of sleep.
REM (Rapid Eye Movement) sleep is active sleep.
NREM and REM
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.
Yes blind peole have REM sleep!!
