REM sleep?

I know that REM stands for rapid eye movement and that REM sleep is a deep, dream-filled sleep. But what else? When does REM sleep begin? What happens to your mind/body during this sleep cycle? What happens if it is interrupted?

Every night you have REM sleep. This is just saying that you are dreaming wildy. Sometimes you just can't remember what you dreamt the night before.  (+ info)

rem sleep??

my baby is a week and a half old. sometimes when he sleeps he will breathe very fast and heavy. i have heard of rem sleep and think this is what he is doing because sometimes he will also make faces and roll his eyes around. anyone else ever saw their baby do this or breathe rapidly in sleep?

i hope you understand exactly what REM sleep is. it is Rapid Eye Movement. which is the deep stages of sleep at which you are dreaming. This is also the stage where you talk and walk in your sleep as well as move around. As the heart is beating faster generally they are having a dream where they are doing somethign that will increase the heart rate. it is definately very common. its really funny when puppies or dogs are sleeping as well as they will some times run in their sleep as well.  (+ info)

REM Sleep??

Ok so I am going to be talking about this at work tomorrow and I was thinking about coming up with a game of some kind. Can someone who is creative give me at least a starting point for this idea. Or come up with a hand out of some kind. Help!

The presenting complaint is violent dream-enacting behaviors during REM sleep, often causing self-injury or injury to the bed partner. The dream-enacting behaviors are usually nondirected and may include punching, kicking, leaping, or running from bed while still in REM sleep.
The patient may be wakened or may wake spontaneously during the attack and recall vividly the dream that corresponds to the physical action.
In some cases, an extended prodrome of prominent limb and body movements occurs before the development of RBD  (+ info)

Do sleep aids replenish your body the way REM sleep does, because i learned they make you skip REM?

In school, i learned that sleep aids made you skip REM sleep, so it would have been better to go with alternative less medicated methods to sleep. I've heard people though say that, on sleep aids they wake up replenished just the same as if they had their REM sleep. So was the information outdate, or possibly something overlooked?

It depends on the sleep aid. I prefer Valerian root pills. They are a natural supplement, and they put me into a deep deep REM. I also don't wake up all groggy, but it is harder to pull me out of sleep. I can't wake up to an alarm. They give you extremely vivid dreams they are really neat.  (+ info)

Is it possible to dream out of REM sleep?

I have learnt that REM sleep is the time when most people have dreams. However, I get dreams while taking short naps of 15 min to 30 min. I often get dreams even with 15 min sleep! Does that make me abnormal or am I just really good at sleeping?

Lol, good question. I always joked that when stressed and sleep deprived, I am the most efficient sleeper ever! I will lie down for a nap and the second my head hits the pillow I am having vivid dreams, which continue for about 30 minutes and then I wake up refreshed, almost out of breath, thinking "wow, that was intense"!

The article in the link below talks about polyphasic sleeping. The idea behind it is that if you are sleep deprived enough, after a while you can train your body to go directly into REM sleep and skip the first phases of the sleep cycle. This allows a person to sleep only in naps throughout the day totally no more than 3-4 hours of sleep per night.

Sooo in short, no you can't dream out of REM sleep, but it certainly sounds like it's possible to train yourself to nap exclusively in REM sleep... you just have to be really sleep deprived.  (+ info)

How can I decrease my amount of REM sleep?

My psychiatrist suspects that I spend too much time in the REM stage of sleep. He mentioned a sleep study perhaps in the future, but is there anything I can do NOW to decrease the amount of time I spend in REM sleep?

Spending too much time in REM sleep is strongly indicative of Narcolepsy. The only way to suppress REM sleep is with a specialty drug called Xyrem which causes the body to correctly go through the sleep cycle rather than always be in REM sleep. So, right now, no there is nothing you can do but to wait until after the sleep study (and I'm assuming a multiple sleep-latency test which is a nap study) until you get the results so the doctor can properly treat you.

Best of luck to you!  (+ info)

What does it mean when you can get little to no rem sleep?

I had a sleep study done and the tech said that I was able to get into rem sleep but I would come out of it quickly. And that I did not get into rem sleep much. What does this mean?

You are not getting enough of the deep sleep you need. I have this problem right now due to having to get up to put wood in the fireplace and take the puppy out. Not fun. Try valarian root, melatonin, chamomile tea before bed and also try puting on something soothing to sleep, like a cd of ocean waves, it really helps.  (+ info)

How long does it take to get in to REM sleep?

People have said that it takes over an hour of sleeping to actually dream but I can nod off for about five minutes and dream anyway. Is there something wrong with me or is that normal? Should i be worried about this? Also, does it have to take that long to achieve REM sleep?
They are not daydreams. I know the difference

Normally, people do not enter REM sleep until about 90 minutes into the sleep cycle. However, some people experience sleep onset REM sleep in which they dream within the first 15-20 minutes. This can be a sign of narcolepsy and is not typically experienced. You are most likely fine, but if you are worried, I would go talk to a doctor and see if you may have a mild form of narcolepsy.  (+ info)

Why is taking a nap before bedtime bad for REM sleep?

I take a nap after getting home because I'm just too exhausted to focus on my work. So, I decide to take a nap, and I wake anywhere from around 11PM to 2 or 3AM, and I go back to sleep again from anywhere around 3-5AM and wake at 6AM. I heard that doing this disrupts the REM cycle. If so, how? And is it really that bad? What are the long term side effects?

REM sleep generally occurs after a few hours of sleep. The other sleep is giving the brain a break, but REM sleep is when your brain is actively processing things. This is also when people seem to dream. So sleeping in shorter blocks gives your brain less time to slip into REM sleep.

I don't think that is a bad thing, as long as you feel refreshed every morning before going to work, it shouldn't be a problem. You probably dream less than other people. so if you like dreams that's too bad. haha

Hope that helps. If you're really concerned, do some research about it.  (+ info)

What are the effects of not getting enough REM sleep?

How many hours of REM sleep should one get to be optimally healthy and alert?
How can one increase the hours they get of REM sleep??

I just did a small report on this topic, heres the basic info of it.

What happens when a rat stops dreaming? In 2004, researchers at the University of Wisconsin at Madison decided to find out. Their method was simple, if a bit devilish. Step 1: Strand a rat in a tub of water. In the center of this tiny sea, allot the creature its own little desert island in the form of an inverted flowerpot. The rat can swim around as much as it pleases, but come nightfall, if it wants any sleep, it has to clamber up and stretch itself across the flowerpot, its belly sagging over the drainage hole.

In this uncomfortable position, the rat is able to rest and eventually fall asleep. But as soon as the animal hits REM sleep, the muscular paralysis that accompanies this stage of vivid dreaming causes its body to slacken. The rat slips through the hole and gets dunked in the water. The surprised rat is then free to crawl back onto the pot, lick the drops off its paws, and go back to sleep—but it won't get any REM sleep.

Step 2: After several mostly dreamless nights, the creature is subjected to a virtual decathlon of physical ordeals designed to test its survival behaviors. Every rat is born with a set of instinctive reactions to threatening situations. These behaviors don't have to be learned; they're natural defenses—useful responses accrued over millennia of rat society.

The dream-deprived rats flubbed each of the tasks. When plopped down in a wide-open field, they did not scurry to the safety of a more sheltered area; instead, they recklessly wandered around exposed areas. When shocked, they paused briefly and then went about their business, rather than freezing in their tracks the way normal rats do. When confronted with a foreign object in their burrow, they did not bury it; instead, they groomed themselves. Had the animals been out in the wild, they would have made easy prey.

The surprise came during Step 3. Each rat was given amphetamines and tested again; nothing changed. If failure to be an effective rat were due to mere sleep deprivation, amphetamines would have reversed the effect. But that didn't happen. These rats weren't floundering because they were sleepy. Something else was going on-but what?
