The Sleep Matrix
Why do we sleep? What governs when or how long we sleep? This activity will assist you in understanding two common sleep theories, recuperation and circadian, which provide different answers to these questions. Depending on which one you support, it may change your outlook on sleep and your current sleeping habits.

Categorize each characteristic under the correct theory—recuperation or circadian—by placing an “X” in the appropriate column. Then, answer the questions that follow.

Recuperation Circadian
Sleep restores the body to a state of homeostasis. x
Sleep plays no role in physiological functioning. x
We become tired when it is dark out. x
Function of sleep is to restore energy levels x
Function of sleep is to conserve energy x
We become tired from wakefulness. x
We sleep until the body is physiologically sound. x
We sleep based on an internal timing mechanism. x
Sleep depends on vulnerability from predators. x
Sleep deprivation may cause behavioral disturbances. x
We have a sleep-wake cycle. x
When we sleep is based on some evolutionary aspects. x

1. What are the main differences between the recuperation and circadian theories? The main differences between the recuperation and circadian sleep theories are that the circadian theory states that we sleep due to an internal clock within us and the recuperation theory states that we sleep to restore our bodies to homeostasis that our body is thrown out by being awake.

2. Which theory do you most agree with? Explain. It is difficult for me to decide which theory I agree most with as both have valid ideas that I can relate to. However, I tend to lean slightly further to the recuperation theory. The reason I favor this theory is the fact that it states that our body sleeps in order to restore itself. The book states that we…...

...Sleep deprivation is defined as a sufficient lack of restorative sleep over a cumulative period so as to cause physical or psychiatric symptoms and affect routine performances of tasks. (WebMd) Sleep deprivation can lead to harsh physical and or mental problems and should be taken seriously. We are now living in a 24/7 world where we are constantly busy and there is work, television and electronics keeping us up. Getting the proper amount of sleep should be taken very seriously so that there are no harmful effects to your body or mind. Sleep is something that you cannot live without, just like the food we need to eat or the oxygen we need to breathe. Sleep may be the last thing we feel there is time for but it should be made a top priority. There are several consequences, such as accidents or disasters, that are a result of sleep deprivation or lack of sleep and everyone should make a conscious effort to improving the way they sleep. Sleep debt is a major factor in accidents and can cause slow or delayed reactions times. Slowed reaction time can be dangerous while driving a vehicle or even operating machinery. Not only could you harm yourself due to a lack of sleep but others could be in harms way as well. An example of sleep deprivation and slowed reaction time would be the Exxon Valdez disaster. This accident was a major disaster in where oil was spilled all over and harmed many living creatures. In “Sleep Debt and the Mortgaged Mind” William C. Dement and......

...A Good Night’s Sleep- What is sleep? Sleep is defined as unconsciousness while are brain is still active processing and rejuvenating period. Sleep is a physical and mental resting period in which a person is unaware of their environment. In a normal sleep our body is changing by decreasing body temperature, blood pressure and other body functions. Sleep is very important to us and everyone for that matter because we all need to sleep and rest our bodies. It’s so important because it’s a vital biological function without sleep we know that our bodies are unable to function the way we want them to. We lose lack of day-time alertness, drowsiness and more susceptible to health problems such as stroke, diabetes, obesity and even depression. In the article ("Good night’s sleep") they discuss about College students sleeping patterns changing for example, not getting enough sleep. I felt that the article didn’t have information about sleeping patterns when there has been research about sleeping patterns. In 2002 Canadian Community health survey found that 18% of people sleep 5 hours or less a day. Sleep is put into two parts one being called non-REM and REM (Rapid Eye Movement). Non-REM consists of four stages of sleep, each deeper than the last. REM is when you are at the most active sleeping you are dreaming and your eyes are moving rapidly. Our sleep patterns consist of stages 1-4. Stage one last about 5 minutes, easily awaken. Stage 2 first stage of sleep about first 25......

...definition of terms. Background of the Study Sleep is an integrated part of human health and life and is crucial for learning, performance, and physical and mental health. Sleep deprivation is a serious problem facing individuals in many critical societal roles. It is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function. Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. Complete absence of sleep over long periods is impossible for humans to achieve (unless they suffer from fatal familial insomnia); brief micro sleeps cannot be avoided. A National Sleep Foundation survey found that college/university-aged students get an average of 6.7 hours of sleep each night. Sleep deprivation is common in first year college students as they adjust to the stress and social activities of college life. A study performed by the Department of Psychology at the National Chung Cheng University in Taiwan concluded that freshmen received the shortest amount of sleep during the week. In 1997 the University of Minnesota did research that compared students who went to school at 7:15 am and those who went to school at 8:40 am. They found that students who went to school at 8:40 got higher grades and more sleep on weekday nights. One in four U.S.......

Outline and Evaluate the Evolutionary Theory of Sleep (8+16 Marks)

...basis of the evolutionary theory is that animals sleep because it serves some adaptive function. The notion of the adaptive nature of sleep comes from the theory of evolution. The idea is that any behaviour that has continued into an animal’s gene pool must have been naturally selected because it has, in some way, aided the survival and reproduction of the animal that possesses that characteristic. One explanation of sleep that the evolutionary theory proposes is that it helps to conserve energy, particularly in warm blooded animals such as mammals which use a considerable amount of energy to maintain their body temperature - This especially true from animals with high metabolic rates such as mice. According to the theory, sleep provides a period of enforced inactivity to conserve energy which Webb explained as the Hibernation Theory of sleep. It is important when thinking about the function of sleep to distinguish between the two different types of sleep, core sleep and other types of sleep. The two main types of core sleep are slow wave sleep (SWS) and REM sleep. It is possible that they both serve a different purpose. Research has shown that energy is only conserved in NREM sleep because the brain is relatively active in REM sleep which suggests that only NREM sleep has evolved for energy conservation. More primitive animals such as reptiles only have NREM sleep, supporting the idea that NREM sleep evolved first for energy conservation and REM sleep evolved later to......

...Sleep deprivation in college students is very common with consequences that affect their physical and mental health. Peer pressure from friends or roommates and the demands of school and jobs leave many teens and college students chronically sleep deprived. Many college kids don't think they need the required hours of sleep necessary for good physical and mental health. In error many think that their youthful energy is enough to keep them going rather than a good 8 hours of sleep. What is sleep deprivation? The best definition of sleep deprivation is found by WebMD. "a sufficient lack of restorative sleep over a cumulative period so as to cause physical or psychiatric symptoms and affect routine performances of tasks." Sleep deprivation is a lack of sleep or not getting enough sleep, unlike insomnia which means a person has trouble falling and staying asleep. Much of society suffers to some extent from sleep deprivation. But ignoring the advice to "get plenty of sleep" has an exaggerated impact on the bodies and minds of college students. Faced with the famous dilemma: "Study, friends, sleep -- pick two," it is often "sleep" that students delete. Sleep deprivation, especially during exam periods, is a way of life for students. A recent study by the National Sleep Foundation (National Sleep Foundation, 2009) )found that “63% of college students do not get enough sleep.” Fifteen percent of college students admitted that they fall asleep in class. Those students who......

...English Importance of sleep. Sleep is very important and beneficial part of our lives. Sleep helps us to have a better quality of life, but nowadays not sleeping well has become part of the lives of many people. The sleep needed is between 7 to 9 hours, but some people get 6 hours or less. Sleep deficiency can be presented at any time of our lives, as adult people, teenagers and even in children. Sleeping well helps us physically and mentally. It is known that sleep plays an important role and helps us to improve our memory, health, learning and metabolism. Also sleep has an big impact on our life and it can bring a lot of consequences such as, long term diseases, car accidents, memory problems, shorter life, lower grades, deficiency at work, mad mood, poor performance exercise and extra activities. One of the consequences that lack of sleep brings is long term diseases. If we do not sleep what we need, we can increase the risk of developing cardiovascular disease and hypertension, metabolic problems such as, obesity and diabetes and emotional disorders such as, depression and bipolar disorder. When we deprive our bodies of sleep, it raises ghrelin which it is a hormone that regulates the need to eat. When we do not sleep, that hormone increases causing us want to eat more when we do not need it, so that is when obesity problems are presented. Also, sleeping decreases leptin which is another hormone that regulates the need to eat and when it decreases, we will have the......

...while it occurs. Sleep is truly a wondrous process. During sleep, our brain takes our bodies through five different stages: rapid eye movement and non-rapid eye movement, otherwise known as NREM, which represent four of the five stages. Each stage corresponds differently in length and produces different brain waves as well as dreams. The first stage of sleep is very brief and the sleeper experiences hypnogogic sensations. Stage two is a deep, twenty-minute cycle, and the third is short in length, much like the first. However, it is also the transitional period into stage four, which lasts thirty minutes long. REM sleep ends the course of the sleep cycle, lasting a total of ten minutes or more. Sleep begins in stage one and progresses into stages two, three, and four. After stage four, stage three and then stage two are repeated before entering REM sleep. The total time it takes for a person’s body to go through all five stages is about 90 minutes. Stage one is a very light sleep. The person is not technically asleep yet, for he/she is easily awakened. During this stage, many people may experience hallucinations that are mistaken for dreams and/or falling/floating sensations. David Meyers defines hallucinations as, “[f]alse sensory experiences, such as seeing something in the absence of an external visual stimulus.” (p.94) Many people will recall being pinned to their bed or floating, when in reality it was the normal occurrences of the first stage of sleep. During......

...Although there is still no satisfying answer to the question of why we sleep, rapid progress in the last several years suggests that this may soon change. Perhaps a better understanding of the function of sleep will also help to change attitudes about sleep at a societal level. The average person requires about eight hours of sleep per night, but many otherwise healthy people continually deprive themselves of adequate sleep with consequences that include fatigue, poor decision-making and increased risk of accidents. Although there is still no satisfying solution to the question of why we sleep, sleep is not a waste of time. Sleep is something that bodies need to do and sleep is a natural part of everybody's life, but many people know very little about how important it is, and some even try to get by with little sleep. It is important for the mind and body to function normally. Every individual is different on how much sleep they need. The younger they are the more sleep you need. As an individual get older he/she does not need as much sleep as he/she would when he/she were at a young age. Most adults need 7 to 8 hours to get the best sleep to function for the next day, during the sleeping hours the body goes into a deep sleep that helps the body be ready for the next day to give the energy that and individual will need. Other people need a nap during the day to function at their highest ability. The body will let your brain know when you are getting tired, and you will......

...Response #2: Sleep Sleep is extremely important to the body and its functions. It is so important, scientists suggest approximately eight hours of sleep a night to improve performance and cognitive functions. Due to having a full time job and being a full time student, I can only get in between five to six hours of sleep a night. Accordingly, not enough sleep I wish I could get nor enough my body needs. Consequently, not having that eight hour sleep, reduces my personal well-being and productivity at school and work. In the “Science of Sleep” video, the researcher found that sleeping can enhance our memory. Therefore, if you study a subject and sleep on it, you will remember the information much better than you would even right after studying it. I think that is quite an interesting fact, since many students believe that staying up all night studying would be more productive. It is very important to know that sleep has this strong effect on a person's memory and learning ability. The part of sleep in memory and learning is poorly understood and has yet to be precisely characterized. Scientists know it is extremely important, not only to rest our body, but our brain. However, they are not exactly sure what happens to our brain while we are asleep. Not sleeping or not sleeping enough can be fatal and can even be compared to not eating, which is particularly surprisingly. The experiment with rats, displayed in the video, was very intriguing. The rats were not allowed to......

Restorative Theory Sleep

...Outline and evaluate the restorative theory as explanation of a function of sleep The restorative theory is suggested to be a purpose of sleep that serves the function of restoring the body in several ways; firstly Slow Wave Sleep (SWS) is said to be the stage of sleep that releases the growth hormone. This hormone is functional for renewing proteins and involved in protein synthesis, and also involved in the immune system in restoring antibodies. This idea is supported by Sassin et al who looked at individuals who "reversed" their sleep cycle, so they were asleep during the day and awake at night, and the growth hormone was still released during sleep, supporting the role of the SWS and release of neurotransmitter, and showing the importance of sleep as a restorative function. Another aspect of the restorative theory as an explanation of sleep, is the idea that brain development takes place during the Rapid Eye Movement (REM) stage, which is why babies have longer REM sleep, as they are processing information such as memories, as well as secreting growth hormone etc. This view is a biological view, and contrasts with the evolutionary theory of sleep which suggests babies have longer REM sleep as an adaptive response for parents to be able to work, hunt etc. However, it has been found that length of REM sleep is directly proportional to the immaturity of the species, for example dolphins have no REM sleep and can swim from birth, compared to the platypus, which is......

...Sleep and brain development: With the relevantly recent discovery of rapid eye movement (REM) sleep, the once subjective state of sleep is no longer expressed as a homogeneous occurrence of passive rest for the brain. Instead, REM sleep has, "appeared as an active condition of intense cerebral activity." (1). And to be even more interesting, the fact that as humans we get more sleep at younger ages, 25 and younger, when intense neurological development is taking place means that, "sleep may play a role in brain maturation." (1). A recent study has research sleep in young children as well as young adults. It has found that, "Sleep and sleep cycles begin at around 26 to 28 weeks' gestational age."(2) This means that patterns of REM and NREM have been found in infants, suggesting that there is some type of development taking place while in a sleeping state. The study goes on to show that, "Sleep and sleep cycles are essential for the development of the neurosensory and motor systems in the fetus and neonate. They are essential for the creation of memory and long-term memory circuits, and they are essential for the maintenance of brain plasticity over the lifetime of the individual." (2) Suggesting that sleep is essential for positive brain development for the rest of the life of that infant or young adults. It was also noted that any interference with sleep or sleep cycles can significantly hinder the early processes of sensory development. (2). It is clear that sleep is......

Sleep

...Over the past few years, I have consistently found myself tired. I could wake up from a deep sleep that ranged from six to eight hours and show still show signs of fatigue. I could be in the middle of doing something and would find myself dozing off. I decided to research how this condition may be affecting me on a daily basis. I also tried to examine what actually may be causing me to experience these. The most common cause of sleep deprivation is that a person may have some sort of a sleep disorder. There seems to be hundreds of different sleep disorders that can affect someone. People can suffer from insomnia, delayed sleep phase syndrome, hypopnea, syndrome, night terrors, rapid eye movement behavior disorder, restless leg syndrome and sleep apnea. Some are very common while others are found in very few patients. I was intrigued by restless leg syndrome because I have heard of it on several occasions. Restless Leg Syndrom is also known as Willis-Ekborn disease is a neurological disorder that causes a person to move uncontrollably at moments where they may feel uncomfortable. It is common referred as RLS and the symptoms can occur anywhere on the body despite the more commonly used name implying that the problem occurs in the leg. There are several symptoms that are common and they can affect a person at almost any age. According to the Restless Legs Syndrome Foundation, around 45% of patients exhibited their first symptoms of the ailments before their twentieth......
