The Effects Of Sleep And Sleep Deprivation On The Body
Michael Ly Professor Hayley Thayer COMM 130 28 September 2014 The Effects of Sleep and
Sleep Deprivation Has on the Body. Specific Purpose: To inform the audience about why we need
sleep and what happens if you are sleep deprived. Thesis: Sleep is crucial for any living creature and
lacking an adequate amount of sleep is detrimental to health. Introduction Attention Getter: Many of
us will spend about a third of our lives sleeping, yet don't know why we need sleep or how
important it is for the body. Did you know you can die faster from sleep deprivation than food
deprivation. Credibility Statement: I am a person who suffers from sleep deprivation, I generally
only have about 4 hours worth of sleep everyday. I am extremely fascinated about sleep and the
impact it has on the body since it is something that affects all living creatures. Preview of Main
Points: First, I will discuss why we get sleepy. Second, I will discuss why we need sleep. Third, I
will discuss the effects of sleep deprivation. II. Main Point: Causes of Sleepiness Transition: We all
know that sleep is important for the body but why do we get sleepy? The amount of light that our
eye receives during the dusk and dawn creates or suppresses hormones that help us sleep. Our eye
has intrinsically photosensitive retinal ganglion cells (ipRGCs) containing the photopigment
melanopsin enable pupillary light responses, photic resetting of the circadian clock, and other
sightless visual responses. When we see artificial

Deprivation: An Unmet Public Health Problem, Sleep Physiology. Rapid Eye Movement(REM) has
been correlated with dreams and sleep physiology. It has been tracked by brain waves and muscle
movements. Non–Rem(NREM) sleep is the first phase which occurs for 1–7 minutes and the easiest
to be interfered with. The brain begins firing betawaves every 15–30 seconds. After a while the
person becomes asleep and breathing regularly between 6–8 seconds in the second stage. The heart
rate begins to slow down and so does the blood pressure. In the third stage there are more
thetawaves along with sleep spindles(sigma waves) and k–waves. Most of the noise are lock out and
the heart rate and blood pressure are decreasing. In the fourth phase there are thetawaves in the
appearance of delta waves firing at 1–5 seconds. The last and final stage, the person is in their
deepest sleep and it is very difficult to wake up. The heart rate and blood pressure are at their lowest
and the delta wave are blasting every 1–5 seconds. The source is creditable but it is a second hand
research because they use different experiments from past authors. This is going to be use in a
research paper because it give plenty of information about sleep and how they believe it has been
caused. Dr. Harvey R Colten was a pediatric

REM and slow–wave sleep
(SWS) have been implicated in memory consolidation [3–5].
Lack of REM sleep is associated with poor recall of visual location [6]. Decline in declarative
memory consolidation is correlated with a decline in slow–wave sleep [7]. Spencer et al. observed
similar initial procedural learning in older and younger adults; however, the older adults'
performance did not improve following sleep, suggesting that sleep dependent memory
consolidation decreases with age [8]. This may reflect the disturbed sleep and disrupted SWS in the
elderly [3,8,9]. Slow wave sleep increases until shortly before puberty and then shows a prominent
drop across adolescence, decreasing by more than
60% between ages 10 and 20 years [10]. It is critical to understand the cognitive effects of normal
sleep in order to understand the consequences of disrupted sleep. This is important since the
majority of adolescents do not obtain the recommended amount of sleep and that disrupted sleep is a
key symptom in most adolescent psychiatric and developmental disorders [11].
Backhaus et al. studied twenty–seven children with an average age of 10.1 years (range of nine to
twelve), on a learned word pairs list, employing a within subject design and two post–learning
assessments. They found that declarative memory was significantly increased immediately after an
interval of sleep, as well as with

Sleep At Anytime During Sleep Time
I would like to sleep at anytime during the day except the sleeping time. Whenever in the dead of

There is a strong evidence that memories are strengthened through deep sleep. The scientists did an
experiments with orangutan by making them a comfortable sleep condition instead of the bed of hay.
Deep sleep seemed to improve the orangutan's cognition: "Whenever orangutan had slept more
deeply, they performed better at memory games" (Barth). Deep sleep not only process good
memories but also deal with sad memories. If I went to sleep feeling upset, a lot of the time I would
l feel better when I wake up, and some experts argued that : "Deep sleep can disarm dangerous
emotions, stripping away the upsetting aspects of it" (Lewis). Moreover, the heart rests and tired
muscles repairs better while deep sleeping. When I was on my "college tests preparation" stage, I
often ate a medicine which treated and improved poor memories. In fact, there is no need to buy
expensive health–medicine or beauty–medicine, deep sleep is the best natural medicine. Every
minute in deep sleep is important for the physical operation, and it separates for several stages that
are recognized by the regular changes. First stage is the one people get into light sleep : " It is still a
relatively light period between being awake and asleep" (Walcutt). It usually takes five to ten
minutes to get through this stage, and the average sleeper usually takes seven minutes. For me, I stay

Rem Sleep : Types And Stages Of Sleep
Most people do not realise how vital of a role REM sleep has on our everyday life. Almost everyone
has remembered when they had had an extremely vivid dream. Well that is because they were in a
stage in their sleep called REM (Rapid Eye Movement) sleep. REM sleep is a part in the sleep cycle
where your eyes move back and forth and is also the part of the sleep cycle where you dream the
most. Our bodies need REM sleep in order to maintain proper function and health. In fact, we are
programmed to sleep each night as a means of restoring our bodies and minds. The internal
biological clock and the sleep–wake homeostat largely determine the timing of our transitions from
wakefulness to sleep and vice versa.Mammals and birds are two of the only type of animals that
have REM sleep. ("Sleep – Types and Stages of Sleep – REM Sleep."). The majority of people have
heard of REM sleep, but do not know much about it. It happens in cycles of about 90–120 minutes
during our sleep and it makes up about 20–25% of an adults sleep time, but the amount of time we
spend in the REM sleep cycle lowers the older we get. The brain cycles through five different
phases during sleep: stages 1,2,3,4 (which are classified by their respective brain wave patterns) and
REM sleep. The sleep cycle repeats itself, so one enters REM sleep several times a night. ("What Is
REM Sleep?") . REM sleep dominates the latter half of the sleeping period, predominantly the hours
before we wake. Scientists that have

Sleep And Non Rem Sleep
Sleep effects every living organism on the world, whether it is positive or negative it has an impact
on everyone. There are many different stages of sleep and each containing its own purpose. Sleep
isn't as simple and unnecessary as many believe it to be; sleep has the power to cause many different
disorders and can even cause death if a person is deprived from sleep for too long. Sleep can also
effect the brain and how the brain functions on a daily basis. Sleep is an important factor of life that
should not be over looked. If enough sleep occurs there are many advantages that can make one's
life more healthy and beneficial. There are distinctive stages of sleep REM sleep and non–REM
sleep and about every ninety minutes we cycle through four recognizable sleep stages (Myers D
2014). Non–REM sleep consists for 3 different stages and during each stage it contains its own
purpose. Stage one occurs for about 10 minutes and is when a person is lightly sleeping and can be
woken up very easily (Mastin 2013). Muscles are still active and movement occurs more frequently
such as twitches and the eyes roll around at a slow pace and breathing and heart rates slow down
(Mastin 2013). Stage two happens between 45–50 percent of the night at different intervals (Mastin
2013). Muscle activity decreases and it is harder to wake up during this stage; if sounds are heard
they are no longer able to make sense of them (Mastin 2013). The last stage: stage three which is
also called delta

I. Introduction A. What is one thing that everyone in this room/ (on earth) have in common? B.
Everyone has at least one thing in common and that is that we all need to sleep. C. I am going to
present the different theories on why we sleep, the sleep cycle, a few of the different sleeping
disorders, and how to sleep better. Transition: We know that everyone needs sleep but why is it
actually important? II. Why is sleeping important? A. There actually isn't any known facts on why
we actually need sleep, but there is many theories. 1. According to the National Sleep Foundation
(NSF), the research that has been done states that sleep is required for normal function. 2. The
average person sleeps around 7–8 hours a night, although, 100 years ago people slept 11–12 hours a
night because there wasn't as much to do in a day. B. Evolutionary theory also called inactivity
theory, one of the earliest theory of sleep. a. This theory states that we sleep to protect ourselves at
night. If we are still and quiet predators will not notice us while were sleeping. i. If you're up at
night trying to hunt for food, you'll more likely to be attacked by a predator because it's too dark out
to see anything, or something coming after you, which leaves you vulnerable to be attacked. C.
Energy Conservation– During the night it is too dark to actually see anything and find prey so it's
believed we sleep to conserve energy for the morning when it's sunny and we can catch prey easier.

Overgeneralization Of Sleep
Sleep is undeniably a necessity for humans and other animals alike. At the beginning of each day,
our bodies awake like clockwork in conjunction with the rising sun. Then, at day's end, they begin to
wind down into sleep until the morning. While there certainly may be plenty of mysteries revolving
sleep that have yet to been unraveled, from all the way up until now and for centuries to come, it is
evident that sleep should hold priority in the schedules of all people. Yet, despite all of this being
true, sleep is consistently being taken for granted. And, it is not an overgeneralization to say that
many people have, at least once, trudged through a late night as many people have. Even to the point
of the night no longer being considered "a ... Show more content on Helpwriting.net ...
Day by day, if one were to consistently voluntarily restrict their sleeping hours, he or she would
gradually build up what is referred to as "sleep debt". Sleep debt defines the cumulative effect of
reduced sleep hours. (Dinges et al., 1997) The more and more the sleep debt grows from not getting
a single good night's rest, the more moody, irritable, and incoherent a person can get. While there are
no limits to the extent of how moody, irritable, and incoherent someone can become, there gets to a
certain point where a person's awareness of how tired or sleepy he or she is goes down. In addition
to that, increased sleep debt has also resulted in a decrease in the responsiveness of cognitive brain
functions. This phenomena is what is being described and what occurred in the introductory
anecdote above. It was not because of the body genuinely feeling less tired and drowsy more so was
it that the awareness of the hypothetical person to recognize how tired he/she was has gone down. In
reality, it will take more than a few hours to fully recover from sleep deprivation. Based on a study
focusing on the effects of cumulative sleep debt, a sample size of 16 adults were chosen and were
forced to sleep approximately 5 hours each night, well under the recommended average. (Dinges et
al., 1997) The results of this study show that there is

After reviewing my sleep not only from the first sleep log but from the time since then I saw I
needed to improve my sleep, even taught it will be a challenge because I will have to decide
between saying up and doing work or going to sleep and both are important, but since I thought my
sleep sort of problem I decide to try to alter even a little. So this was and still is important for me, I
decide that I will leave a note on my laptop reminding me thus preventing me from procreating s
much as I would have before, as well as having my boyfriend enforce this; I felt having someone
remind me of my goal and make me think of the consequence and benefits and this did prove
helpful, but it was still challenging to pick between sacrificing work for sleep. Other steps I took to
assure that I will stick to my plan was, installing flux to my lap top, turning on night shift, setting
one or two alarm in the morning without snooze, eliminating the light that comes through my
window. Mostly importantly reminding myself that at one point i had reached a time where I would
consistently go to bed in the morning when the sun would rise and it did become difficult to get
back to a normal sleeping pattern and I don 't want to experience those stressful nights of staying in

The Sleep Cycle
Sleep Cycle Sleep cycle is the process where a person is asleep and goes through four or five
different stages of non– REM (non rapid eye movement) also known to be called quiet sleep and
REM (rapid eye movement) known as active sleep. In the beginning of these stages you are not fully
asleep you are still alert to things around you because of beta waves these waves are what the brain
produce they are small but very fast waves. After these waves produce other waves start producing
called alpha waves they relax your body and slow everything down throughout your body. A full
sleep cycle is about 90 minutes long most cycles can be about 100 to 120 minutes. All the cycles can
be shorter for some people and especially for children when they ... Show more content on

It is a device like clock that the brain may use to control certain things in the body at the right time,
the circadian clock is in charge of keeping the body temperature the right degree also release
chemicals into the body when needed. One chemical that is releases is neurotransmitters this is
released at night to help drop your temperature and makes you feel tired. In the morning the same
thing happens but it releases neurotransmitters to help you wake up. For example people who wake
up very early can't sleep in and the reason behind that is because their body has a cycle to release
neurotransmitter early in the morning which means they can't sleep in late when they are wanting
too. Circadian rhythms are very important for us to wake up every morning without it we would
need another chemical to wake us up that we do not

Nocturnal Sleep
In this article, the researchers attempted to discover that learning a new word requires an
"incubation period" for the word to be processed and remembered, and this period is commonly
connected to sleep (Dumay & Gaskell, 2007, p. 35). The authors hypothesized that "nocturnal sleep
(along with its physiological and neural correlates) enables listeners to lexicalize spoken words,"
and the researched assumed that sleep allows this information to be stored into long–term memory
(Dumay & Gaskell, 2007, p. 36). Furthermore, they assumed that an "increase in lexical activity
induced by exposure to a novel competitor (e.g., ''cathedruke'') would produce longer PD latencies
to a neighboring existing word (e.g., ''cathedr_al'')" (Dumay & Gaskell, 2007, p. 35). In the

To listen to these words, participants wore a pair of headphones and listened to each of the 24 novel
words a total of 36 times in the exposure phase (Dumay & Gaskell, 2007, p. 37). Then, in the
lexicalization test, the participants took a forced choice test and were instructed to push one of the
two buttons in order to determine if there had been a pause in a spoken stimulus (Dumay & Gaskell,
2007, p. 37). Then, participants were instructed to give a free recall period to state as many of the
new words as possible (Dumay & Gaskell, 2007). Then in the 2–AFC recognition test, participants
heard the new word along with its foil and were given a forced choice test and were instructed to
push a button when one of the words sounded familiar. In addition to the initial test, "The
subsequent retests (12 and 24hr) used the same test battery but involved no exposure phase" (Dumay

Sleep Deprivation And Sleep Disorders
Since, technology has become more about of society there has been a trend in people who are not
getting a full night's rest. According to the National Commission on Sleep Disorders Research, "at
least 40 million Americans suffer from chronic, long–term sleep disorders" (Sleep Disorders and
Sleeping Problems"). There are several causes for the increase in lack of sleep or sleep deprivation;
which include, using electronics late at night, using your bed for more than just sleeping, and
anxiety.
As a result, of more American's using electronics late at night, using your bed for more than
sleeping, and increased anxiety has caused society to constantly lose a good night's rest. There are
many people who every now and then don't sleep well, but there are several who experience what is
called sleep deprivation: "Sleep deprivation is a condition that occurs if you don 't get enough sleep"
("What Are Sleep Deprivation and Deficiency?"). There are several dangers with so many
American's being sleep deprived such as increase chance of falling asleep while driving or even
increased work injuries: "Lack of sleep exacts a toll on perception and judgment. In the workplace,
its effects can be seen...accidents. Sometimes the effects can even be deadly, as in the case of
drowsy driving fatalities" ("Consequences of Insufficient Sleep"). For the purpose of public safety,
American's should be aware of the dangers of sleep deprivation starting with how using electronics

Sleep : A Sleep Cycle
Sleep is needed in everyone's life because the body and mind need to rest in order for you to
function fully. Sleeping disorders are common in many people life, according to the book "there are
about 81 different types of sleeping disorders" (Engdahl, 18). Most people do not get the
recommended eight hours of sleep because their schedule does not allow them to sleep, it is
recommended to create a sleep cycle so that your body can adapt to the time you are awake and shut
down for the hours that you are sleeping. Studies have shown that not getting enough sleep can
cause obesity, depression and even heart disease. This disorder is uncontrollable because it can come
from genetics. Another reason why it is uncontrollable, some people have night terrors which occur
while you are asleep. Not controlling your thoughts and waking up to a scary dream or thought,
depending on their reaction it can cause them a stroke, heart attack or they might pass out. When
you hear someone snoring you often take it as a joke and you laugh at the person because of the
obnoxious sound coming from them, while they don't know that they are snoring. Snoring is a
common symptom in some sleep disorders, snoring can have risks on a persons sleep because it can
clog your throat and nose and you could choke in your sleep and never wake up. Some sleep
disorders can be treated, some people don 't ever realize that they have a sleep disorder. This
disorder has many effects some which can change a person

Sleep Analysis Essay On Sleep
Sleep Analysis As we learned in lecture, sleep is an important component in improving a person's
overall health. Because sleep is vital for cognitive function and available time to spend sleeping is
limited for college students, like myself, it is advantageous to change sleeping behaviors to
maximize the benefits sleep can provide. After tracking my sleeping schedule for a week, I have
noticed some patterns and behavior that may be affecting the quality of sleep I am getting. Based on
my sleep journal, I could improve my sleep by cutting back on the amount of caffeine I intake and
the time spent on electronics before bed to try to reduce the amount of time needed for me to fall
asleep. I tracked my sleep for one week early on in the semester when I was less busy and able to
get more sleep, however the overall patterns in how I felt when waking up and trouble falling asleep
have remained mostly the same. In this particular week, I got an average of about nine hours of
sleep per weeknight. The recommended amount of sleep per night is between eight to nine hours
(Teague 77). I would say I need at least eight full hours of sleep a night to feel like I am well rested.
I did not occur a sleep debt during this week, however I have experienced weeks were I did
accumulate a sleep debt. When this occurs, I usually try to make up for it by sleeping in on the
weekends rather than napping. I have found that taking naps isn't an effective way for me to reduce
my sleep debt because I

Sleep Deprivation Of Sleep Affecting The Brain
of sleep is seen as an adaptive move to keep humans from wandering in the night. How we sleep?
We go from waking to sleeping, then we get a little deeper into our sleep, sleeps spindles generate
periods of extreme activity. Then we go deeper and deeper as delta waves come from our brain
waves go lower. During REM (Rapid Eye Movement) the brain is hyped, blood pressure increases
causing the heart rate to increase in speed. REM is also crucial in the strong ties we have in
memories. REM Rebound goes up REM after decreasing it.
Children to teenage have better percentages of REM due to adults' sleeping patterns being screwy
due to their everyday tasks. Sleep deprivation effects performance in concentration and attract

Sleep And Memory Of Sleep Essay
Introduction There are a few factors that are essential for life such as breathing or eating, but one of
the most essential factor is sleep. Even though the amount of sleep people need differs from one
individual to another, the fact is that eventually everyone needs to sleep. People know the
importance of sleep, but due to the increased workload and the pressure of society people are getting
less sleep. As a result, there has been an increase interest on the effects lack of sleep has on the mind
especially the memory of a person. Many questions arose about the relationship between sleep and
memory due to the fact most high school and college students have become sleep deprived. For
example, does more sleep mean higher grades? There have been many experiments performed
trying to find the correlation between sleep and memory. One of these experiments has showed that
different stages of sleep has different effects on memory for instance, not only has sleep been seen to
combine new memory with old long–term memories, but also helps stabilize memory (Born &
Rasch, 2013). Using the Memory Interference Test (MIT), Amir conducted an experiment to further
confirm the conclusion that the sleep improves a person's memory. The experiment compared the
amount of correctly remembered pictures by a sample people who had eight hours of sleep
compared to a sample with only four hours of sleep. The hypothesis is that there is a correlation
between the amount of sleep a person

Theories Of Sleep
One of the most fascinating natural occurrences known to science is something everyone's body
requires them to do, this strange phenomenon is sleep. Sleep is not fully understood by anyone,
there are too many variables and unanswered questions to discover what sleep is for and why the
human body stresses sleeping so much. Dreams are just as undiscovered as sleep. There are many
observations made about dreams and what parts of the brain are utilized during these inter–sleep
hallucinations. But like sleep, there is no official reason or meaning behind it. Sleep and dreams,
although strange and without apparent purpose, reveal many things about an individual, his or her
habits, and potentially innermost subconscious thoughts.
Despite the unanswered questions and the unknown factors behind sleep and dreams, there are many
theories behind their purposes. Many popular sleep theories have to do with keeping out body and
mind in top shape. Some examples of sleep theories are: protection, recuperation, memory
restoration, and growth. (Myers, 2014) All of these theories are beneficial to the body and its
functionality. The protection theory assumes that the feeling of sleep kicks in when it is dark or
dangerous out and danger is more prevalent. ... Show more content on Helpwriting.net ...
Dreams reveal to a person his or her most passionate desires, emotions, and worries. These two
things reveal many things about people as well. It can be observed that a person that rarely sleeps
may be stressed out, or maybe that his body operates on a slightly different circadian rhythm, or
even that the person is just very busy. Dreams can reveal a lot about emotion If a person has violent
dreams very frequently it can be assumed that he or she could feel angry, frustrated, or vulnerable.
Although sleep and dreams have an unsolidified purpose, sleep and dreams benefit the body and
mind in many ways by creating a better performing body and

Rem Sleep : Types And Stages Of Sleep
REM Sleep Most people do not realise how vital of a role REM sleep has on our everyday life.
Almost everyone has remembered when they had had an extremely vivid dream. Well that is
because they were in a stage in their sleep called REM (Rapid Eye Movement) sleep. REM sleep is
a part in the sleep cycle where your eyes move back and forth and is also the part of the sleep cycle
where you dream the most. Our bodies need REM sleep in order to maintain proper function and
health. In fact, we are programmed to sleep each night as a means of restoring our bodies and minds.
The internal biological clock and the sleep–wake homeostat largely determine the timing of our

animals that have REM sleep. ("Sleep – Types and Stages of Sleep – REM Sleep."). The majority of
people have heard of REM sleep, but do not know much about it. It happens in cycles of about 90–
120 minutes during our sleep and it makes up about 20–25% of an adults sleep time, but the amount
of time we spend in the REM sleep cycle lowers the older we get. The brain cycles through five
different phases during sleep: stages 1,2,3,4 (which are classified by their respective brain wave
patterns) and REM sleep. The sleep cycle repeats itself, so one enters REM sleep several times a
night. ("What Is REM Sleep?") . REM sleep dominates the latter half of the sleeping period,
predominantly the hours before we wake. Scientists

Pathophysiology Of Sleep
Introduction In the past few years, cell phones and tablets have begun to take over people's lives.
Cell phones hold our entire lives on them, from what time we wake up in the morning to directions
to get everywhere. People spend the majority of their lives on their cell phones, texting, tweeting, or
even just playing games. Not only do these devices effect our social lives, but they also affect how
we sleep at night and how much sleep we get. Sleep is very important in maintaining homeostasis
and proper health, in order to function properly, "healthy adults need between 7–9 hours of sleep
each night" (helpguide). If a person does not get the amount of sleep– they need, then they will
become groggy and less efficient at work or school. ... Show more content on Helpwriting.net ...
The blue light from electronics, "pass through the retina into a part of the hypothalamus (the area of
the brain that controls several sleep activities) and delay the release of the sleep–inducing hormone,
melatonin" (WebMD). The light from the screens throws off the body's natural sleep and wake
system, also known as the circadian rhythm. The circadian rhythm tells the body when to release
melatonin; the chemical that tells the body when to sleep, as well as serotonin; the chemical that
tells the body when to wake up. The brain releases melatonin when the sun goes down to begin to
prepare the body to go to sleep, blue light reverses the effects of melatonin and wakes the brain back
up. Serotonin is released when the sun comes up to wake the brain up and make the body alert and
ready for the day, if the person does not get enough sleep then the serotonin levels will be low and
they will be less awake and alert. According to Harvard Health, when blue light begins to throw off
the circadian rhythm, the risk for cancer begins to increase and the risk for obesity increases as well.
However, blue light is beneficial during the day as it boosts energy and mood as well as alertness, at
night blue light has the same affect, which is why it keeps the brain awake. Blue light is in many
energy efficient lights, which stimulate the brain as

excessive sleepiness, disruptions, to repeated awakening associated with nightmares. According to
The Gale Encyclopedia of Science, sleep–related problems have been the most frequent complaints
both psychiatrists and doctors have received (Thompson, 2004). This is an important disorder to

A detailed patient history is used for most of the sleep–wake disorders in order to get a basis of the
patient. Questions such as when the symptoms began, the duration, predisposition and other details
that may provide more information are used. These may be inquired by questionnaires, and
interviews of both patient and patient bed partner (D. Sue; D.W. Sue; D. Sue; S. Sue, 2014, p. 428).
Sleep diaries in which a person writes down their schedule can also be used. These will allow the
assessor to differentiate between dyssomnia or parasomnia . Dyssomnia is the difficulty someone
has in falling asleep, maintaining sleep and extreme tiredness throughout the day (D. Sue et al.,
p.425). The dyssomnias involve several disorders which include insomnia, hypersomnolence,
narcolepsy, sleep apnea, and circadian–rhythm sleep wake disorder. Insomnia. Parasomnia is the
abnormalities occurring during the sleep– wake transition. Non–rapid eye movement sleep arousal
disorder, nightmare disorder, and rapid eye movement sleep disorder are some of the results caused
by parasomnias. Physical or psychological tests may be necessary to check that the symptoms are
not caused by another underlying factor. A person may also test in a clinical lab in order to be
observed. Often times the patient will be monitored and recorded throughout the night.

The Effects Of Sleep And Variables On Sleep
This paper will cover the scientific study of sleep and variables which impact sleep by examining
the five different stages of sleep, evaluating dreams and nightmares, assessing the causes and effects
of sleep disorders and the various types of treatments, in addition to the effects of food and drugs on
sleep. There are five stages of sleep, numbered one through four and REM (Rapid–Eye–Movement)
sleep. Upon falling asleep, the brain and body goes through each stage to comprise sleep cycle
which approximately has a duration of 90 minutes. Stage One commences when the body and brain
begin to relax. During this stage, heart beat slows down, breathing becomes regular, and blood
pressure tends to decrease (Huffman. K, 2011, p.174). In addition, brain activity starts to shift,
moving from beta waves to the slower alpha waves. Despite being deeply relaxed in this stage, it is
still very easy to be awakened (Huffman. K, 2011, p.174). Following Stage 1, the mind and body

Abstract
I was a sophomore in High School in New Haven , Michigan when In school I decided to walk
home and skip school, my house was empty at the time so I decided to go into my room and take a
nap and that's when it happened for the very first time. I had awakened and I felt this heavy weight
on my body and another feeling that I can only describe as if someone is lying on top of me, forcing
me down (hence holding my whole body down) holding my lips and eyelids shut. I could hear
though. This lasted for about 10 seconds. During these 10 seconds all sorts of thoughts started
running through my mind questioning the reality of this phenomenon and even extended to states

Post–traumatic stress disorder (PTST), fatigue, heavy physical activity, extreme changes in physical
activity, jetlag and other stress–related conditions may bring about sleep paralysis due to the
disturbance of sleep cycles. Some researchers have also reported a link between childhood sexual
abuse and sleep paralysis. Numerous researches have also been done linking final stages of
pregnancy to sleep paralysis.

Sleep Walking
Abstract Sleepwalking, also known as somnambulism, is a sleep disorder belonging to the
parasomnia family. Sleepwalking is a disorder that occurs when people walk or do another activity
while they are still asleep. These activities can be as benign as sitting up in bed, walking to the
bathroom, and cleaning, or as hazardous as cooking, driving, having sex, violent gestures, grabbing
at hallucinated objects, or even homicide. The prevalence of sleepwalking in the general population
is estimated to be between 1% and 15%. SLEEPWALKING Sleepwalking, formally known as
somnambulism, is a behavior disorder that originates during deep sleep and results in walking or
performing other complex behaviors while asleep. It is belongs to the Parasomnias ... Show more

Babies and children spend most of their time in this stage, but as we grow older we spend less time
in REM. (Blackman, 2000) * Non–REM sleep Non–REM sleep is a much deeper, more restful kind
of sleep. In non–REM sleep, the person's body is free to move around. Non–REM dreams are more
likely to consist of brief, fragmentary impressions that are less emotional and less likely to involve
visual images than REM sleep dreams and are more frequently forgotten. The period of Non–REM
sleep is made up of four stages. 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. People begin the sleep cycle with a period of non–REM sleep followed by a very short period
of REM sleep (Chang, 2010). A machine called an electroencephalograph (EEG) allows scientists to
see the brain wave activity as a person passes through the various stages of sleep to determine what
type of sleep the person has entered ( Aserinsky & Kleitman, 1953). A person who is wide
awake and mentally active will show a brain wave pattern on the EEG called beta waves. Beta
waves are small and fast. As the person relaxes and gets drowsy, slightly larger and slower alpha
waves appear. The alpha waves are eventually replaced by even slower and larger theta waves. Non–
REM Stage 1: as theta wave activity

Sleep Deprivation And Sleep
Sleep is very important in a person's day to day activities. Sleep allows a person to be more aware of
their surrounding and allows one to use their minds to the highest potential. Unfortunately, there are
plenty of people due to their jobs or even by their own choices are sleep deprived. Sleep deprivation
can affect one's behavior and their cognitive functions in different ways. Goel pointed out that
"deteriorate effects have been shown to involve vigilance, executive attention, working memory,
language, divergent thinking, and creativity (Maccari 2014)." Much research has been done on how
sleep deprivation effects brain functions and behavior. Many are not aware to what extent the brain
is effected by sleep deprivation and how one's behavior can drastically change.
In order to fully understand how one's mood is effected by sleep deprivation, one must first
understand how the brain functions during sleep. Rapid eye movement, or REM sleep, is one of the
phases that the brain goes through during sleep. During REM sleep, the eyes move back and forth
and it is believed this is due to the visual images that one is seeing in their dream. Jouvet was the
first to show that the brainstem is integral for the REM sleep stage, and the neural circuits in the
pons have also been studied thoroughly to see how it plays a role in the sleep cycle. The medulla
also contains neurons that are active during REM sleep. However, it is very unclear how big of a
role the medulla plays in the

My Sleep On Sleep Patterns
I have fallen asleep every night for the last 22 years, but yet I never analyzed my own sleep pattern.
Never truly aware of what time I fell asleep, whether I dreamt every night, or the quality of my
sleep. All I knew was that the older I got, the more lethargic I got, and the more caffeine I
consumed. Now given the opportunity to monitor my sleep for five nights with the use of a sleep
diary I have better knowledge of my sleep patterns. Basing my sleep patterns on concepts learned in
class, I was able to understand my sleep, and apply different issues I experienced each night to the
resolutions I learned. Hopefully, after my sleep diary I will know how to improve my quality of
sleep on a regular basis based on concepts learned in class. On the first night I was on the verge of
excitement about starting my sleep diary so I fell asleep at 11:29 P.M. I assumed I would have a
regular nights' sleep, until I heard my name being called. Feeling like I was in a horror movie I
awakened instantly in fear, to a cold sweat and rapid heartbeat. Let's face it, my name is not a
common everyday name, so I was terrified until I recalled hypnagogic hallucination. Hypnagogic
hallucinations occur at the onset of sleep (NREM) as the small, fast beta brain waves turn into large
slower alpha brain waves (140). As I checked the time it was only 11:32 P.M. making this the
perfect explanation for this bizarre phenomenon. I then proceeded to fall back to sleep, and woke up
at 6:00 A.M. However

Sleep Deprivation And Sleep Deficiency

English 4 AP
6 Oct. 2015
Sleep Deprivation: A Bane to Men, Women and Children alike It was 12:30 am in the morning and
Israel Joubert and his family was driving home after a family reunion. Joubert had hoped to get to
his workplace on time at 8 am in the town of Fort Worth. However in the midst of his driving,
Joubert fell asleep at the wheel resulting in a crash of the family's Chevy Suburban into the rear of a
parked 18–wheeler. Although one of his sons and he had survived, his wife and five kids were
killed. (Fryer) In the article titled "Sleep Deprivation and Sleep Deficiency", Sleep Deprivation is
defined as a "condition that occurs if you don't get enough sleep". The fact of the matter is, sleep
deprivation manipulates millions of people who are ignorant about the adverse effects of sleep
deprivations to do devastating harm to not only themselves but others that they might deeply love.
Due to the adverse physiological effects to humans, sleep deprivation will continue to undermine
human society by taking advantage of sleep–deprived humans. Therefore, it is essential to inform
the public about measures to prevent and treat sleep deprivation. In order to understand the effects of
sleep deprivation, one must first understand how the body makes does one go to sleep. First off, the
human body is built with an internal body clock which controls when one is awake and when one's
body is ready to go for sleep. Known as the circadian rhythm, this

Gurdjieff Sleep
The most famous statement of Gurdjieff in this context is that, "Man is asleep. He is born in sleep,
lives in sleep and dies in sleep. Life for him is only a dream from which he never awakes. He lives
in a sleep–waking world moving about in the twilight of consciousness and yet imagines himself to
be awake" . 'Sleeping' here stands for not being aware. It is interesting to note that Buddha is called
as awakened one. It was not the case that Buddha before he attained to Nirvana was sleeping all
throughout. Then why is he called as an awakened one? Because though Buddha was awake from
worldly point of view, he was actually sleeping from the point of view of awareness. Consciousness
does not mean wakefulness. Even animals are conscious but they are sleeping from the point of
view of awareness. In fact, when we wake up from dreaming, we immediately realize how unreal
that dream was. But while we are dreaming, in the midst of dreaming, the dream is totally real. In
fact, we even physically respond to the dream by changes in our breathing pattern, by palpitations of
the heart, by changes in sweating and by hormonal secretions. Like we wake up from the dream, in
the same manner Gurdjieff talks about waking up from our 'waking sleep'. ... Show more content on

(sleeping–sleep); 2. our Jagrut avastha or wakeful state for him is again subjective consciousness but
less than the earlier state (waking–sleep); 3. The third state of consciousness he refers to as 'Self–

Objective Consciousness (seeing the world objectively). The first two states of consciousness
characterize the ordinary man. Thus though all of us can claim that we are conscious, we cannot
claim that we are aware. There is hardly in 'Self–remembering' in us in Gurdjieff's

Sleep Deprivation And The Sleep Cycle
Sleeping is very important for everyone as it helps our body to rest and recover its energy. Anyone,
who doesn't sleep well, can have many disorders that we will discuss later. We have first to explain
what is a typical night`s sleep cycle then go ahead and describe how sleep deprivation impacts your
ability to learn and your health as well. Regular night`s sleep cycle can always be described in 4
stages N1, N2 and N3. Where each stage has different information and different description. N1 can
be said for light sleep. N2 is for sleep spindles. N3 is for the delta waves. Also there is REM and
NREM sleep which defers from one stage to another. First stage will be N1 which is light sleep. In
this stage your body starts to adjust itself and the other organs that it is about to stop working.
Where at this stage the body drift between sleeping and out of sleep and it can be easily awakened
from this stage. This stage affects the eye movement as it makes it move slowly and the muscle
activity as well starts to relax. Many people said that they experienced sudden muscle contraction.
There is also a hypnagogic images as hallucinations or vivid visual events and hypinc jerk for the
knees, legs and sometimes for the whole body Second stage is N2, which can be expressed by sleep
spindles as it is accompanied by stop of eye movement and different stuff.in this stage, the body
relaxes to the extreme as it stopes the eye movement and brain waves starts to slow down with an
occasional

Sleep Reflection
I learned a lot about myself, my sleep patterns and how they are affecting my mood and
performance throughout the day. I found that I sleep a lot better and get to bed earlier on nights that
I workout. The problem was that i was tired but stayed up later than I should have because I lost
track of time while on my phone. Also when I would put my phone down to try to go to sleep, my
mind was still racing. I was either thinking about school from that day or events and homework that
I needed to get done the next day. This caused me to stress a little and kept me up, which was stupid
of me because I can not control the future. Also on the days that I felt stressed at school, lead to a
worst night of sleep. The one thing that was pretty consistent, and I feel helped me, was my diet
which was pretty good during the week. This lead to me sleeping more soundly and I did not wake
up throughout the night. No drugs were taken during the week but i did take dietary supplements
throughout the days. I feel like this helped with my energy levels throughout the day and helped me
to sleep through the night. This left me as well rested as possible with the limited sleep that I got,
which was my fault. My sleep schedule stayed somewhat consistent minus the day where I had to
wake up at 4:30 am. On the weekend I slept in longer than usual which threw off my consistency a
little but I felt better rested those days. The days during the week kept pretty consistent with a 6:30
am wake up time.

Sleep And The Brain : Sleep Deprivation
Sleep & the Brain Sleep is the mysterious shift in consciousness that our bodies require every day
(sleep council). Sleep scientists have explored these changes in depth, & their definition of sleep is
tied to characteristic patterns of brain waves & other physiological functions (Harvard, 2008). There
are many different risk factors that can come up if we do not get the sleep our body needs to
function. One serious effect due to the lack of sleep would be sleepiness can cause accidents.
According to Camille Peri, sleep deprivation was a factor in some of the biggest disasters in recent
history: the 1979 nuclear accident at Three Mile Island, the massive Exxon Valdez oil spill, the 1986
nuclear meltdown at Chernobyl, & many others (Camille, 2005). The first thing that came to my
mind when thinking about what happens if we do not get sleep was the safety risks being on the
road. Every day I drive 40 minutes to either work or school & while driving on the interstate I have
noticed many times people swerving into the other lane. Semi–truck drivers are at a huge risk for
these accidents because most of them barely get any sleep so that they are able to make all the trips
required to get through the week. My step–father drove a truck Monday through Friday and I
remembered him telling me how little sleep he would get just to make sure he got his work done so
he could come home on the weekends. Drowsiness can slow reaction time as much as driving drunk
can (Camille, 2005). The

The Effects Of Sleep On Sleep Pattern
Everyone knows sleep is important. But what most people don't know is that if you do not have a
healthy sleep pattern, you do not get the proper benefits. Your sleep pattern is your daily rhythms of
sleeping and waking. It is best to try and keep a consistent bedtime and wake up time. Signs that you
are experiencing a disruptive sleep pattern are difficulty falling asleep, frequent awakenings during
the night, and/or waking too early. For example, I know I have a disruptive sleep schedule because I
cannot stay asleep and I wake too early. Falling asleep is easy for me, but I always awaken
somewhere between 1 and 4. Sometimes I can fall back asleep within 10–20 minutes, but other
nights I am up for hours. Because of this more often than not I am awake before my alarm. Impaired
sleep can cause a lot of side effects, which I will explain in the next paragraph. There is an
abundance of things that can impair your sleep, many of which can be easily avoided. For instance,
today's society is completely overrun by technology. Almost everything can be done via computer,
smartphone or tablet. Thus, we are constantly using them. Studies show that the use of technology
can significantly impair your ability to sleep. Experts say you should stop using technology at least
2 hours before bed, yet the majority of people bring their phones to bed with them. This causes
many people to become over stimulated, causing sleep problems. Other things that can impair your
quality of sleep are

Sleep Deprivation And The Sleep
Sleep is a basic necessity of everyday life. According to the National Foundation of sleep, a person
is required to sleep at least seven to nine hours a day. (citation) As mentioned by Matt T. Bianchi in
the book Sleep Deprivation and Disease, " The normal quantity of sleep depends on the individual
and a myriad of other factors such as environment and an individual 's waking needs." (citation)
This means that the quantity of sleep that people achieve depends on their body's needs and
functions. Unfortunately, according to the Nation Foundation of Sleep, twenty percent of individuals
are affected by sleep deprivation each year. This a huge number. Sleep deprivation is a lack of the
required sleep a person needs in a week . It can come in ... Show more content on Helpwriting.net ...
The percentage decreases after the age of fifty. Both quality and quantity are important when it
comes to sleep. If one fails to acquire the appropriate amount of R.E.M sleep and sleeps less than six
hours everyday for one week, then that person would have a total sleep debt of seven to fourteen
hours. The effects of not sleeping properly can be felt as soon as the next day.
As mentioned before, there are two types of sleep deprivation, partial sleep deprivation and total
sleep deprivation. A person is considered partially sleep deprived if he or she gets less than five
hours of sleep per night. If a person gets less than three hours of sleep per night, then he or she is
considered sleep deprived. Sleep deprivation can either be caused by lifestyle or medical issues.
Factors such as drinking coffee at night, obesity, stress, insomnia, and sleep apnea negatively affect
the way one sleeps. As mentioned previously, sleep deprivation can affect one's physically. Some of
these effects include: obesity, type two diabetes and heart disease. Most of these effects are cyclical.
This means that it is a repeating process.
Obesity is a physical illness which results in the extreme production of fat and cholesterol. Obesity
is an increasing problem in the U.S. According to the World Health Organization (WHO), Obesity
has more than doubled since the 1980's. In the 2014, six hundred million adults aged eighteen and
up, were suffering from obesity. Obesity

The Effects Of Sleep Timing, Sleep, And Sleep Duration On...
Abigail Morales Encinas BIO–201L 10/22/2015 Dr. Stephanie Stang The Effects on Sleep
Timing/Quality/Duration on Academic Achievement Abstract: The purpose of this study was to
observe the effects of sleep timing, sleep quality, and sleep duration on academic achievements in
young adults. Those who participated in the study were thirty–six Italian seniors in high school. In
order to determine their ideal sleep timing, they each filled out the Morningness–Eveningness
Questionnaire for Children and Adolescents (MEQ–CA). For two non–consecutive weeks, students
underwent actigraphy, which is a non–invasive method of monitoring human rest and activity
cycles. This was done in a one month period, and was able to assess factors such as: habitual sleep
timing though the midpoint (MS); habitual sleep quality through the parameter of sleep efficiency
(SE); and habitual sleep duration through the parameter of total sleep time (TST) (Tonetti, Fabbri,
Filardi, Martoni, Natale, 2015). At the end of each actigraphic–recording week, the students
completed the Mini Sleep Questionnaire, and their school performance were assessed by the grades
achieved after taking final exams. 1. Introduction Circadian preference is the main focus and what is
being tested in this study. People who are morning types and evening types are expressions of
human circadian rhythms and mark the most inter–individual differences (Tonetti et al., 2015). From
ages up to 10 the preference usually is morning

To Sleep is to Dream
I have often had dreams that were so real and vivid, that I was unable to tell if they truly happened
or occurred in my dreams. Sleeping is very important to everyone. Without proper sleep, the body's
immune system can begin to fail, and then one will become more susceptible to virus, illnesses, and
disease. Even when we are asleep, the human mind does not completely sleep. When we are asleep,
we tend to tune out environmental sounds that occur when we sleep. For example, I live near a
freeway, yet the sounds of it never wake me. The auditory cortex in our brains respond to stimuli
even when we are asleep. For example, I can always wake up when one of my children calls my
name while I am in a deep slumber. There have been many studies and observations on individuals
while they are asleep. These studies are done on individuals who have sleep disorders. There are
four phases of sleep, and when one does not get the proper sleep, physical and mental issues will
occur. Our bodies work in tides, and our minds and bodies fluctuate. When our bodies seem to
synchronize with the 24–hour day, it is referred to as the circadian rhythm. It is the biological clock
that tells us when it is day time we are awake, and night time is when we are supposed to sleep. Age
and experience can affect the circadian rhythm, and I see this in myself. For instance, when I was in
my teens and twenty's, I had no problem staying up all night, whether it was working a graveyard
shift, or

good sleep habits. Discuss the impact this environment has on preterm infants in terms of their
neuropsychological development and sleep patterns. Consider the longer term implications, and the
measures that can be taken to minimise or overcome these. By Nidhi Introduction In this topic we

Intensive Care Unit) ward environment have impact on the neuropsychological and sleep patterns of

Different authors looked at different variables as well as used their own methods in reducing light,
noise and movement. Comparing all of the studies, it was difficult to find any strong patterns or
consistencies between studies apart from the inclusion of light in more than one study. It is evident
that in this field, different researchers have analysed different variables and used different methods,
which makes it challenging to fully solve this problem in preterm infants. In terms of the overall
hypothesis, there is inconclusive evidence and not enough studies done in the area about the effect,
if any, of light and noise on the neuropsychological development and sleep patterns on preterm
infants. Despite the limited number of studies on the variable of movement, all researchers agreed
that movement (tactile/kinaesthetic stimulation) had positive effects on a range of developmental
outcomes of preterm infants. Ultimately, the fact that Physicians have complained about the
detrimental impact of unacceptable high levels of these variables in the environment of the NICU
ward, and nothing has been done to change it yet paints a very bleak picture for the neonatal preterm
infants of the future. Only two studies suggested new solutions for this ongoing problem, but yet
again none of these have been tried, tested or proven in real cases. The fact that there are barely any
studies done on the variable of constant movement makes problems in this field of research even
more challenging to solve, hence the need for further interest and research on the specific variables
of constant movement, light and noise if we are going to provide and create a healthier NICU
environment and future for our next

Sleep And Sleep : Sleep Schedule Look Like
If you have a roommate that comes back to your room at all hours of the night, this can severely
affect your life as a whole. Sleep is essential to the human body performing in a variety of tasks. If
you are constantly being woken up at various times throughout the night, it can have negative
consequences on your impact to learn and your health. So what does a typical night's sleep schedule
look like? A typical night's sleep is much more complicated than just closing your eyes and waking
in the morning. As humans, we live our life on a circadian rhythm. This means that changes occur
roughly based upon a 24–hour basis. This circadian rhythm plays a major role in when we get tired
and decide it's time to sleep. This rhythm is theorized to have helped us stay safe thousands of years
ago. We would fall asleep during the time that their seemed to be threats roaming around in the dark.
to Once we finally get to sleep, our brains and bodies are doing much more than laying in complete
stillness. There are five distinct stages of sleep that we experience as we sleep. Each is uniquely
different and serves a purpose throughout the night. The first stage of sleep is a very light sleep that
lasts for 5 to 10 minutes. During this stage of sleep, you may not even realize that you're sleeping.
While in this stage of sleep our brains power down by 50 percent and produce theta waves four to
seven times per second. We proceed to stage two after this. During stage two, our brains power
down
