Why is rem sleep called paradoxical sleep?
REM sleep is sometimes referred to as paradoxical sleep by scientists because it is a period of sleep characterized by rapid periodic twitching movements of the eye muscles and other physiological changes, such as increased breathing and heart rate, increased brain activity, and muscle relaxation. REM sleep also known as paradoxical sleep is the stage of sleep in which vivid dreaming takes place and is thought to allow for the organization of memories and the retention of learning as well being paralyzed within this stage.

none. Benzodiazepines decrease slow wave (stage 3 and 4) sleep and only mildly suppress REM sleep. however, no benzodiazepines increase REM sleep. A piece of non-medical, anecdotal evidence to the contrary: I use the Zeo sleep clock to track my REM, deep and light sleep in minutes every night as I… have pretty bad insomnia. After days of very little REM (under an hour) I took one xanax .25mg at bedtime, then another at 3:00a.m.-same dosage- and got 1 hour, 56 minutes of REM sleep. I haven't repeated b/c I don't want to become dependent, and it could have just alleviated anxiety and allowed me to catch up on a REM deficit. But it certainly didn't seem to suppress REM either.

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. ( Full Answer )
It is sleep that seems deep but is not. Typified by REM (Rapid eye movement), brainwave patterns similar to those when awake, and heavier breathing.
rem stand for rapid eye movement if you miss out on this sleep you become cranky and sometimes even see things that arent there. it is the time in your sleep when you dream even if you don't remember it
REM sleep is when you do most of your dreaming. Moreover, lighter REM sleep dreams are those that make sense and can be remembered for a long time. So, one way to tell if you're getting REM sleep is if you're dreaming.. You might also choose to have a Polysomnograph, commonly known as a sleep study…. A trained technologist can tell if you're getting REM sleep from the readings provided by the various sensors they apply to your skin. ( Full Answer )
Because during a REM stage your brain produces waves with a frequency and amplitude similar to beta waves. Beta waves have short frequencies and low amplitudes. These are the waves that are most common when you are most awake. Basically: you look asleep, but your brain is wide awake. REM sleep is wh…en we remember our dreams, so it makes sense that our brains are most active when we are dreaming, seeing as that dreams require a lot of mental activity. ( Full Answer )
Yes, people who have severe sleeping disorders, like narcolepsy, never reach rem sleep. If you drink large amounts of alcohol before bed, it also prevents you from getting rem sleep.
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 sleep is important because this it the stage of sleep helps our brains develop.
Usually between the first and second hour of falling asleep. A person could have up to five periods of r.e.m. throughout one night's sleep.
Valium, Halcion, to name a few. In fact, however, I don't know if there is one that inhibits REM. Having said that, certain drugs have different effects depending on the user. But if you haven't already, I would definitely experiment with your doctor's approval ones that work for you.. There may al…so be an undiscovered, underlying cause for your absent or lack of REM which would be better diagnosed and treated by a psychiatrist or neuroligist.. Hope this helps..

Well you may feel depressed. If you ever dream then you do indeed enter REM sleep. It could be that you have sleep apnea, which is a sleeping disorder in which your airway (consist of the mouth, the nose, throat & windpipe) is obstructed. The obstruction can happened in different places e.g. your …throat or nostril. What happens is your breathing will stop temporarily and then start again. The lack of oxygen will signal your body to wake up so that you continue to breathe. This makes it difficult for you to go into deep sleep or REM sleep especially if your case is severe. If you are often sleepy at work/during the day, feel tired & people complained that you snore (most of the time, but not necessarily always), seek out advice from a doctor. There's a painless sleep test - where you may need to overnight at the clinic to determine how severe your case is. Do not take this lightly as having severe sleep apnea can cause many problems.

No. Rapid Movement Sleep is non-existent. That is referred to as a different condition. REM is actually Rapid Eye Movement. Look it up through google for a prognosis and diagnosis, but all you need to know is its a sleep condition that occurs often in the elderly and children.
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 yo…ur 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. ( Full Answer )
There are five stages of sleep. Stage 1 being the one you first enter, then followed by stage 2, 3 and 4. As you descend into deeper sleep your brain frequency slows down. In stage 4 can it be slower than one cycle per second (delta sleep). After some time spent in stage 4, about 25 minutes,… you return to stage 3 and 2, then straight into REM sleep. About 90 minutes has passed now since you started sleeping. 5-10 minutes is spent in this stage before you go all the way down to stage 4 again (also called non-REM sleep). When approximately 90 minutes have again passed, another REM-period start. This time the REM sleep lasts longer. And as time progresses less time in non-REM sleep is needed and more time is spent in REM sleep. After 4-5 hours you don't go lower than stage 2. Vivid dreaming takes place in REM sleep, so the more you sleep, the more time is spent in REM. ( Full Answer )
REM sleep usually occurs in cycles during the last 5-6 hours of an8-hour night's sleep. So how much sleep we get in this stage willdepend on how much sleep we get for the night. During REM sleep,eye movements increase, heart rate increases, and the normal bodyprocesses also increase. It's during thi…s stage that dreams occur,and it's also this stage that we're most likely to wake up in themorning (feeling refreshed). These REM periods last approximately20 minutes and can occur between 4 and 6 times per a good nightsleep. Unlike the non-REM stages, our major muscle groups don'tmove, so we won't sleepwalk or "jar" ourselves awake during REMsleep. There are different types of sleeps associated with the sleepcycle. It is important to get a full cycle of REM sleep. REM sleepinvolves active dreaming. People sometimes have up to five cyclesof REM nightly. ( Full Answer )
I was probably implanted in ancient humans so that they don't act our their dreams or roll off a cliff while sleeping.
You will know when someone is in REM sleep when there eyes-lids are moving really fast back and forward. REM sleep is a sleep that is after your first 4 stages of sleep and is the stage of sleep that you dream.
REM sleep happens when you are deeply asleep, so you should be able to sleep without being disturbed for at least a few hours, since it may take that long. Although it can happen faster.
REM sleep occurs a few times throughout a night's sleep and lastfrom about 90-120 minutes each cycle. The longest period of REMsleep occurs closest to the morning.
yes you can sleep walk or wile you sleep your eyes experience rappid eye movement (REM)
No. I am a Martian and I get more than a Human. Pathetic weaklings, all you Earth-beings.
Contrary to popular belief, sleepwalking occurs in the deepest stages of sleep, called delta-wave sleep or stage 4 sleep. REM sleep, by contrast, is rapid eye movement sleep, during which the body is in a near-paralysis state.
Absolutely! My dog even goes into rem sleep every night. I love watching his eyes and paws twitch and his lips curl and sometimes i can even hear him huff and growl. It is truly hilarious. He looks like hes chasing something. I know it seems like something in Sims or cartoons but it really happens.
Sleep spindles occur during stages 2 of sleep, they are brief bursts of frequency in our brain wave patterns
I think your brain activity would be so sluggish that you would be more likely to have some secondary cause of death like a motor vehicle accident or falling down a flight of stairs or something. Your brain wants, needs REM sleep so badly you probably wouldn't be able to really go without so much sl…eep that your brain actually ceased to function. It may not be functioning properly, but any tiny amount of REM sleep is rejuvinating for your brain. I'd think that holding still for ten seconds in a state like that would put you to sleep. ( Full Answer )
Labratory studies performed on smaller mamels, like mice, do showthat death can result from lack of REM sleep.
REM sleep is basically the deep restorative sleep required by the body for proper healing and functionality.
The longest REM cycle occurs in the early morning hours. This is why it's easier to lucid dream on weekends, longer hours of sleep in the morning.
Yes, to a great extent. It depends on the persons hold on his own sub-conscious.
It varies throughout the night. A single REM cycle can last anywhere from five minutes to an hour.
In sleep apnea people enter REM sleep just fine. The problem is that when the muscles relax in the first part of REM sleep the airway collapses and they stop breathing. This interrupts the sleep cycle and they get poor sleep amongst other problems. Not entering REM sleep causes what is known as "…REM sleep behavior disorder". They do not have the normal paralysis that accompanies the dream stages of REM sleep so they may act out dreams. Sleepwalking is one example. For more information see the link below. ( Full Answer )
No, during REM sleep, the brain is active, however any muscle activity is suppressed to prevent you from acting out dreams. During stages 3 and 4 of NREM sleep sleepwalking is known to occur.
No. This is normally just a brief period following stage 4 sleep, after which the sleep cycle repeats itself again.
Yes. Oxycodone (OxyContin is nothing but slow release oxycodone) has been shown to prolong sleep stages 3 & 4, similar to alcohol, meaning that to get the same amount of "deep sleep" while medicated as you would not under the influence, you'd have to sleep for a longer period of time. This can pose …a problem as well, since a large number of those who use oxycodone have trouble staying asleep for long periods of time. ( Full Answer )
Just the opposite, alcohol suppresses REM sleep. That's why after a really good night out on the town, you sleep all day because you've been deprived of restorative, mainly REM sleep. MA, RPSGT
REM Sleep = Rapid Eye Movement Sleep NREM Sleep = Non-Rapid Eye Movement Sleep During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep. The period of NREM sleep is made u…p of stages 1-4. Each stage can last from 5 to 15 minutes. A completed cycle of sleep consists of a progression from stages 1-4 before REM sleep is attained, then the cycle starts over again. . Stage 1: Polysomnography (sleep readings) shows a reduction in activity between wakefulness and stage 1 sleep. The eyes are closed during Stage 1 sleep. One can be awakened without difficulty, however, if aroused from this stage of sleep, a person may feel as if he or she has not slept. Stage 1 may last for five to 10 minutes. Many may notice the feeling of falling during this stage of sleep, which may cause a sudden muscle contraction (called hypnic myoclonia). . Stage 2: This is a period of light sleep during which polysomnographic readings show intermittent peaks and valleys, or positive and negative waves. These waves indicate spontaneous periods of muscle tone mixed with periods of muscle relaxation. The heart rate slows and the body temperature decreases. At this point, the body prepares to enter deep sleep. . Stages 3 and 4: These are deep sleep stages, with stage 4 being more intense than Stage 3. These stages are known as slow-wave, or delta, sleep. If aroused from sleep during these stages, a person may feel disoriented for a few minutes. ( Full Answer )
Some sleep research has estimated that about 90% of vivid dreams occurs during REM sleep. More recent studies suggest that other, less intense dream take place during other sleep stages.
In reality, REM sleep involves a mix of activity (bursts of eye movement and brain activity similar to alpha waves) and inactivity (body paralysis as the brain stem prevents cortex activity from reaching the rest of the body). This activity-paralysis mix gives REM sleep its other name: paradoxical s…leep. Adults tend to spend about 20 to 25 percent of an average night in REM sleep. A person would be more likely to be exhausted by too little REM sleep than by too much. ( Full Answer )
The body repairs any & all damaged cells, tissues, etc; cleans up the body, etc.
About 1 hour and 30 minutes. Unless you follow (something like) the Uberman Sleep Shedule. In that case you can get 6 times 20 minutes of REM sleep, distributed over 24 hours (so 2 hours in total).
REM sleep is rapid eye movement sleep, it is a deep phase of sleep and is associated with dreaming.
Truly "deep" sleep does not occur during REM sleep. REM sleep is when you are dreaming. It is deeper than light sleep, but not as far down in unconsciousness as "deep" sleep.
Depends how long. If talking a few days than you get tired, memory negatively impacted, increased irritability... If talking a few weeks then psychosis and eventual death may occur from lack of sleep.
REM means Rapid Eye Movement and only when REM sleep occurs does your body truly start to sleep and without Rem sleep you would wake up not feeling rested EVER.
The dreams that we remember tend to only occur during REM sleep. However, new research is showing us that dreams can actually happen in NREM sleep. Research is still being done to determine exactly what kind of dreams when have in the different stages of sleep.
REM sleep, also called rapid-eye movement sleep, is when dreams occur. Our brain is more active during REM, it generates 'smaller and faster brain waves' (Hockenbury 142). The first stage or episode of REM is brief, lasting between 5-15 minutes. NREM sleep (non-rapid-eye-movement, is when brain acti…vity slows down. NREM sleep is grouped in four stages. Stage 1 lasts only a few minutes during which you teeter on the edge of sleep and consciousness. During this stage it is very easy to be woken up by the littlest sounds. During stage 2 breathing becomes rhythmical. Stage 3 and stage 4 of NREM "are often referred to as slow-wave sleep" (Hockenbury 142). Sleepwalking is known to occur during this stage.

The frequency of your brain waves during REM sleep are beta (which incidentally occurs during the waking state as well). These are low voltage, high frequency waves.
When awake, most people exhibit beta waves , the highest in frequency and lowest in amplitude, They are desynchronous that is, the waves are not very consistent in their pattern. When relaxed most people exhibit alpha waves , which are slower, increase in amplitude and become more synchronous …. The first stage of sleep is characterized by theta waves , which are even slower in frequency and greater in amplitude than alpha waves. Stages 1 and 2 are relatively "light" stages of sleep. A sleeper passes from the theta waves of stage 1 and 2, to the delta waves of stage 3 and 4. Delta waves are the slowest and highest amplitude brain waves. This is the deepest stage of the sleep cycle. The next stage is REM sleep, a sleepers brain waves demonstrate characteristics that are similar to waking sleep, a combination of alpha, beta, and desynchronous waves. This is the stage of sleep most associated with dreaming. In a normal night's sleep, a sleeper begins in stage 1, moves down through the stages, to stage 4, then back up through the stages, with the exception that stage 1 is replaced by REM, then the sleeper goes back down through the stages again. One cycle, from stage 1 to REM takes approximately ninety minutes. This cycle is repeated throughout the night, with the length of REM periods increasing, and the length of delta sleep decreasing, until during the last few cycles there is no delta sleep at all.

There is no specific time period. It lasts for about 20-25% of the total time you're asleep.
