Rem Sleep Research Paper

Researchers have classified two definitive types of sleep, REM, otherwise known as rapid eye movement, and non REM and have divided the sleep cycle into four distinct stages. REM sleep is associated with dreaming as most of our dreams occur during this stage. REM waves are very fast and resemble beta waves which indicate that you are awake. REM sleep is usually

Some 25 to 30 percent of American adults are affected by sleep disturbances of one type or another, according to the National Institutes of Health. In addition, disruption of the sleep-wake rhythm typifies many different neuropsychiatric disorders and is understood to exacerbate them.

To get the most of our sleep both quantity and quality are important. Adults need about 8 hours and on average 9 ½ hours of interrupted sleep. Sleep helps us thrive by contributing to a healthy immune system, and can also balance our appetites by helping to regulate levels of the hormones ghrelin and leptin which play a role in our feelings.

There are two distinct phases of human sleep. One phase is non-REM sleep, and the other is REM sleep. Non-REM sleep takes place in the first few hours of sleep at night, and REM sleep takes over the remaining hours allowing us to have dreams. Non-REM sleep is normally referred to as the resting state for our brain. Intense studies have discovered that the brain is less active during the phases of non-REM sleep compared to phases of being awake.

Although scientists are unsure why we sleep, they do know how sleep works. There are two phases of sleep: Rapid Eye Movement (REM sleep), and Non-Rapid Eye Movement (NREM sleep). These phases help form whole sleep cycles, and a complete cycle lasts around ninety to a hundred ten minutes. If you sleep for eight hours, you will go through about five cycles every night. During these cycles, you are mostly in NREM sleep. REM sleep only lasts for about ten minutes of the cycle. However, as the night progresses, NREM sleep decreases and REM sleep increases. Every cycle of sleep has five stages. In stage one, you will get NREM sleep. You begin to lose muscle tone, which causes twitches and hypnic jerks. You also have hypnagogic hallucinations and

Sleep is a basic human need, it affects how we function on a daily basis and is essential for a person’s health and well being. Sleeping allows the body to recharge and affords the brain the opportunity to integrate important facts, memories and emotional impressions recorded from the previous day. There are five stages of sleep that people go through: Stages one, two, three, four, and Rapid Eye Movement (REM). Sleep is important for all human beings but the amount of sleep each person needs is dependent on many different factors, for example age. Infants generally need sixteen hours of sleep a day, teenagers need about nine hours, and for most adults, seven to eight hours a night is ideal. If people do not sleep enough for several nights they

The last type of sleeping disorder is narcolepsy, this is defined as an abnormal amount of daytime sleepiness. Narcolepsy is a very strange thing, at one moment a person can be fully awake, then the next they can be sleeping anywhere. It is an uncontrollable urge to just fall asleep. This disease is incurable, but treatment can help with the frequency of the attacks, the helpful treatments include therapy, medications, and seeing a specialist. The cause of narcolepsy is not well understood, but many believe it is due to the genetic factors or from abnormal signaling in the

As life goes on it is known that we spend less time sleeping. In comparison – newborns sleep from 16 to 20 hours a day, between the ages of one and four this decreases to around eleven to twelve hours. In this way it continues and finally an adolescent doesn’t need more than about nine hours of sleep per night. Middle-aged adults require up to eight hours of sleep and when it comes to the elderly they may still need these same hours but they might sleep in spurts waking up now and then. As time goes on sleep patterns tend to change and older infants and young children will be able to sleep through an entire night and also have daytime naps. By the age of six or seven children no longer require the naps. Finally as adults they tend to sleep only during the night rarely having any afternoon naps.

There are so many different issues associated with sleeping. Just to name a few different sleep issues are sleep apnea, restless leg syndrome, jet lag, and narcolepsy. Most people have some sort of trouble of sleeping but when it becomes an ongoing issue this is when it is time to consult with a doctor. Problems that are ongoing or reoccurring are called sleep disorders. Sleep disorders can affect your everyday life and can lead to serious problems. Not getting enough sleep can have a negative impact on your energy, emotional balance, and health. In the article, Sleep Disorders and Sleeping Problems it states, “According to the National Commission on Sleep Disorders Research, at least 40 million American’s suffer from chronic, long term

Normally a person sleeps 8 hours a night gives or take a few hours, but it is extremely crucial for your body to get the proper amount of sleep. Actually, some people can get by with as little as 3 hours, and some people would most gladly take more than the 8 hours, but why is sleep so important? Sleep is important because it is associated with growth in the body, hormones regulations, and it relaxes the muscles when in sleep, but not having enough sleep will leave a person to be sleep deprived. In other words, this will be about how sleep affects the human body, while sleeping, or when a person is awake.

Kids always get out of thinking when it comes to make them sleep at night. With that children can have the most comforting sleep and make themselves get a better time all day. Kids are soft in nature and would like to get a better choice of living with parents and friends. For that there are a lot of things that need to remember. This is going to be beneficial in every aspect.

Sleep is a trait that the majority of all life forms on this earth share. However, there are many who are uniformed on just how important it truly is and how much it differs between each individual. There are many researchers who have spent copious amounts of time trying to determine what healthy sleeping is, allowing people who feel they might have sleep complications to check in and see whether or not they need to consult their doctor. The National Sleep Foundation wrote a paper in 2012, which defines healthy sleep as “Falling asleep within 15-20 minutes of lying down to sleep, regularly sleeping a total of seven to nine hours in a 24-hour period, sleeping continuously-not having long periods of lying awake, and waking up feeling refreshed.”

Adequate sleep is important for sustain a good body shape. Sleep maintains a balance between hormones like ghrelin, leptin that are responsible for hunger. Insufficient sleep interrupts the balance and thereby increases appetite, as a result leading to excess fat18. Excessive day sleepiness (EDS) and fatigue are common symptoms of obesity and are linked to an individual's health issues.

NREM (non-rapid eye movement) sleep is the light and deep stages of sleep “initiated by withdrawal of neurotransmitters from the reticular formation and by the inhibition of arousal mechanisms in the cerebral cortex.” The reticular formation found in the brainstem is primarily responsible for generating REM sleep, and NREM sleep is produced by projections from the reticular formation and other areas of the mesencephalon (midbrain). Normal sleep happens in cycles of NREM and REM sleep. When a person falls asleep, he first enters into a light sleep and then progresses into increasingly deeper stages of sleep (NREM cycle) for about 90 mins, followed by the initial stage of REM sleep, the two cycles alternating throughout the night. For people suffering from narcolepsy, sleep begins immediately with REM sleep and portions of REM happens involuntarily throughout the waking hours. As mentioned earlier, REM sleep is when muscles are paralyzed and when dreams take place, explains the associated symptoms of cataplexy, paralysis and hallucinations (McCance & Huether, 2014; "National Sleep Foundation,"
