The following tips may help improve REM sleep:. Following the same bedtime routine every night prepares the body and mind for sleep.

A regular bedtime routine may help to maximize the amount of time asleep, potentially increasing the number of REM sleep phases experienced.

Loud sounds, warm temperatures, and bright lights can interrupt sleep. For optimal sleeping conditions, switch off cell phones and other sources of noise, and remove light sources from the bedroom.

Keep temperatures between 60 and 67 degrees Fahrenheit. A healthy adult requires hours of sleep a night.

Sleeping less than this reduces the number of REM sleep phases experienced. As moderate to high levels of alcohol intake before bed can reduce the number of REM sleep phases experienced, and any amount delays entering the first REM phase, it is advisable to avoid alcohol consumption in the hours before bed.

The relative amount of REM sleep varies considerably with age. The first REM episode occurs about 70 minutes after falling asleep.

Cycles of about 90 minutes each follow, with each cycle including a larger proportion of REM sleep. In the weeks after a human baby is born, as its nervous system matures, neural patterns in sleep begin to show a rhythm of REM and non-REM sleep.

In faster-developing mammals this process occurs in utero. The proportion of REM sleep then decreases significantly in childhood. Older people tend to sleep less overall but sleep in REM for about the same absolute time, and therefore spend a greater proportion of sleep in REM.

Rapid eye movement sleep can be subclassified into tonic and phasic modes. Processing of external stimuli is heavily inhibited during phasic REM, and recent evidence suggests that sleepers are more difficult to arouse from phasic REM than in slow-wave sleep.

On recovery nights, an individual will usually move to stage 3 and REM sleep more quickly and experience a REM rebound , which refers to an increase in the time spent in REM stage over normal levels.

These findings are consistent with the idea that REM sleep is biologically necessary. After the deprivation is complete, mild psychological disturbances, such as anxiety , irritability , hallucinations , and difficulty concentrating may develop and appetite may increase.

There are also positive consequences of REM deprivation. Some symptoms of depression are found to be suppressed by REM deprivation; aggression may increase, and eating behavior may get disrupted.

Several reports have indicated that REM deprivation increases aggression and sexual behavior in laboratory test animals. Mean body temperature falls continually during this period.

It has been suggested that acute REM sleep deprivation can improve certain types of depression when depression appears to be related to an imbalance of certain neurotransmitters.

Although sleep deprivation in general annoys most of the population, it has repeatedly been shown to alleviate depression, albeit temporarily.

Thus, researchers have devised methods such as altering the sleep schedule for a span of days following a REM deprivation period [85] and combining sleep-schedule alterations with pharmacotherapy [86] to prolong this effect.

Antidepressants including selective serotonin reuptake inhibitors , tricyclics , and monoamine oxidase inhibitors and stimulants such as amphetamine , methylphenidate and cocaine interfere with REM sleep by stimulating the monoamine neurotransmitters which must be suppressed for REM sleep to occur.

Administered at therapeutic doses, these drugs may stop REM sleep entirely for weeks or months. Withdrawal causes a REM rebound.

Although it manifests differently in different animals, REM sleep or something like it occurs in all land mammals as well as in birds.

The primary criteria used to identify REM are the change in electrical activity, measured by EEG, and loss of muscle tone, interspersed with bouts of twitching in phasic REM.

Sleep deprivation experiments on non-human animals can be set up differently than those on humans. The "flower pot" method involves placing a laboratory animal above water on a platform so small that it falls off upon losing muscle tone.

The naturally rude awakening which results may elicit changes in the organism which necessarily exceed the simple absence of a sleep phase.

Some researchers argue that the perpetuation of a complex brain process such as REM sleep indicates that it serves an important function for the survival of mammalian and avian species.

It fulfills important physiological needs vital for survival to the extent that prolonged REM sleep deprivation leads to death in experimental animals.

In both humans and experimental animals, REM sleep loss leads to several behavioral and physiological abnormalities.

Loss of REM sleep has been noticed during various natural and experimental infections. Survivability of the experimental animals decreases when REM sleep is totally attenuated during infection; this leads to the possibility that the quality and quantity of REM sleep is generally essential for normal body physiology.

While the precise function of REM sleep is not well understood, several theories have been proposed. Sleep in general aids memory. REM sleep may favor the preservation of certain types of memories : specifically, procedural memory , spatial memory , and emotional memory.

In rats, REM sleep increases following intensive learning, especially several hours after, and sometimes for multiple nights.

Experimental REM sleep deprivation has sometimes inhibited memory consolidation, especially regarding complex processes e.

REM deprivation seemed to impair declarative i. According to the dual-process hypothesis of sleep and memory, the two major phases of sleep correspond to different types of memory.

Artificial enhancement of the non-REM sleep improves the next-day recall of memorized pairs of words. Sleep researcher Jerome Siegel has observed that extreme REM deprivation does not significantly interfere with memory.

One case study of an individual who had little or no REM sleep due to a shrapnel injury to the brainstem did not find the individual's memory to be impaired.

Antidepressants, which suppress REM sleep, show no evidence of impairing memory and may improve it. Graeme Mitchison and Francis Crick proposed in that by virtue of its inherent spontaneous activity, the function of REM sleep "is to remove certain undesirable modes of interaction in networks of cells in the cerebral cortex", which process they characterize as " unlearning ".

As a result, those memories which are relevant whose underlying neuronal substrate is strong enough to withstand such spontaneous, chaotic activation are further strengthened, whilst weaker, transient, "noise" memory traces disintegrate.

One explanation for this correlation is that the PGO electrical waves, which precede the eye movements, also influence memory.

REM sleep prevails most after birth, and diminishes with age. According to the "ontogenetic hypothesis", REM also known in neonates as active sleep aids the developing brain by providing the neural stimulation that newborns need to form mature neural connections.

Ioannis Tsoukalas of Stockholm University has hypothesized that REM sleep is an evolutionary transformation of a well-known defensive mechanism, the tonic immobility reflex.

This reflex, also known as animal hypnosis or death feigning, functions as the last line of defense against an attacking predator and consists of the total immobilization of the animal so that it appears dead.

Tsoukalas argues that the neurophysiology and phenomenology of this reaction shows striking similarities to REM sleep; for example, both reactions exhibit brainstem control, paralysis, hypocampal theta rhythm, and thermoregulatory changes.

According to "scanning hypothesis", the directional properties of REM sleep are related to a shift of gaze in dream imagery.

Against this hypothesis is that such eye movements occur in those born blind and in fetuses in spite of lack of vision.

Also, binocular REMs are non-conjugated i. In support of this theory, research finds that in goal-oriented dreams, eye gaze is directed towards the dream action, determined from correlations in the eye and body movements of REM sleep behavior disorder patients who enact their dreams.

David M. Maurice , an eye specialist and semi-retired adjunct professor at Columbia University, proposed that REM sleep was associated with oxygen supply to the cornea, and that aqueous humor , the liquid between cornea and iris, was stagnant if not stirred.

According to the theory, when the animal is awake, eye movement or cool environmental temperature enables the aqueous humor to circulate.

When the animal is sleeping, REM provides the much-needed stir to aqueous humor. This theory is consistent with the observation that fetuses, as well as eye-sealed newborn animals, spend much time in REM sleep, and that during a normal sleep, a person's REM sleep episodes become progressively longer deeper into the night.

However, owls have REM sleep, but do not move their head more than in non-REM sleep [] and is well known that owls' eyes are nearly immobile.

Another theory suggests that monoamine shutdown is required so that the monoamine receptors in the brain can recover to regain full sensitivity.

It is based upon the observation that REM sleep in several mammals the rat, the hedgehog, the rabbit, and the rhesus monkey is followed by a brief awakening.

Snyder hypothesized that REM sleep activates an animal periodically, to scan the environment for possible predators. This hypothesis does not explain the muscle paralysis of REM sleep; however, a logical analysis might suggest that the muscle paralysis exists to prevent the animal from fully waking up unnecessarily, and allowing it to return easily to deeper sleep.

Jim Horne, a sleep researcher at Loughborough University, has suggested that REM in modern humans compensates for the reduced need for wakeful food foraging.

Other theories are that REM sleep warms the brain, stimulates and stabilizes the neural circuits that have not been activated during waking , or creates internal stimulation to aid development of the CNS ; while some argue that REM lacks any purpose, and simply results from random brain activation.

Recognition of different types of sleep can be seen in the literature of ancient India and Rome. Observers have long noticed that sleeping dogs twitch and move but only at certain times.

The German scientist Richard Klaue in first discovered a period of fast electrical activity in the brains of sleeping cats.

In , Ohlmeyer reported minute ultradian sleep cycles involving male erections lasting for 25 minutes. Dement , discovered phases of rapid eye movement during sleep, and connected these to dreaming.

Their article was published September 10, Neurosurgical experiments by Michel Jouvet and others in the following two decades added an understanding of atonia and suggested the importance of the pontine tegmentum dorsolateral pons in enabling and regulating paradoxical sleep.

I am rather surprised that publications about dream recall during slow wave sleep increase in number each year. Further, the classic distinction established in the s between 'poor' dream recall, devoid of color and detail, during slow wave sleep, and 'rich' recall, full of color and detail, during paradoxical sleep, is beginning to disappear.

I believe that dream recall during slow wave sleep could be recall from previous paradoxical sleep. Sleep Medicine Reviews. Allan Journal of Sleep Research.
