REM Sleep Deprivation

By: arabinda003

Because of the relationship with dreaming, REM (rapid eye movement) sleep happens to be the theme of intense investigation. Sleep scientists have distinctively deprived sleeping subjects of REM sleep by waking them up all the time a contest of REM sleep begins.

REM-seep deprivation has two chronic impacts. First, with each successive night of sleep deprivation, there is a greater possibility for factors to initiate REM experience. Thus, as REM-sleep deprivation proceeds, subjects have to be roused more and more routinely to keep them from accumulating amounts of REM-sleep. For example, during the first night of REM-sleep deprivation, the subjects have to be awakened 17 times to keep them from having extended periods of REM-sleep. During the seventh night of deprivation they had to be awakened 67 times. Second, following REM sleep deprivation, subjects display a REM rebound. They have more than their usual amount of REM sleep for the first two or three nights.

However, one newest theory about REM sleep is based on the conclusion that this type of sleep serves no critical function. This is the typical theory of REM sleep. According to this theory, it is difficult to stay relentlessly in Non-REM sleep, so the brain periodically turns to one of two other states. If there is any bodily need to take care of (e.g., eating or drinking), the brain switches to wakefulness. If there is no immediate need, it switches to the default state REM sleep. According to the default theory, REM sleep and wakefulness are similar states, the REM sleep is more adaptive when there are no instant bodily needs. Indirect support for this theory comes from the many common characteristics between REM sleep and wakefulness.

One of the most necessary revelation of human sleep deprivation research studies point out that individuals who are deprived of sleep become more efficient sleepers. In specific their sleep has a higher equilibrium of slow-wave sleep (stages 3 & 4), which seems to help main restorative function.To demonstrate it may be opened that people who take anti-depressants to overcome depression tend to get less REM-sleep and more non-REM (slow wave) sleep.Basically short sleepers usually get as much slow wave sleep as long sleepers do.
