Recommended: MAIN POINTS OF WHY importance of sLEEP

Located in the cortex of the brain and forming the folding outer layer, gray matter encourages brain growth; however, different parts of the cortex mature faster than others (National Institute of Mental Health, 2011). For example, areas that control basic functions such as movement and processing information taken in by the senses develop first, and those with more complex purposes, such as controlling impulses and planning ahead, develop later (National Institute of Mental Health, 2011). Without sufficient sleep, these areas cannot properly develop, and sleep is central to psychological and physiological development. Adolescents sleep later and wake up later due to the changes occurring in their circadian rhythms (Minges, Redeker, 2015). …show more content…

For children in modern society, sleep seems to be an afterthought, where school and extra-curricular activities “should” take precedent over physical health. The delayed starting time theory involves pushing the starting time back 25 to 60 minutes, which would increase the total sleep-time for most adolescents anywhere from 25 to 77 minutes of sleep per weeknight. Syncing the sleep schedule with the physiological circadian rhythm is a pivotal part of normal growth and development in childhood and adolescence, especially regarding the brain. Mental ability, alertness, learning capacity, and overall daytime functioning may benefit from improved sleep, as disrupted sleep-wake cycles and restricted sleep also have consequences on the kidneys and the cardiovascular, digestive, thermoregulatory, and endocrine systems (Minges, Redeker,

  • Circadian Sleep Essay

    1023 Words  | 3 Pages

    When most people think of sleep, they think of it as a relaxed but yet not a very important part of our daily lives. What most people don’t understand is although we are not up and moving around and getting tasks completed, our brains are still very active. Without sleep our bodies do not function correctly on a daily basis, and our mental state is at risk.

  • Later School Start Times

    1404 Words  | 3 Pages

    All children need sleep and want sleep during the weekdays and that is very difficult. It has been noticed that older students and younger students, such as third graders and eleventh graders, sleep patterns are very different. In many places it is the same way that middle schools and high school start earlier than elementary schools. The problem is that adolescents stay up at least two and a half hours later than younger children do (Bergin 2).

    Throughout the United States, students tend to complain about how early school starts in the morning. A few schools in the U.S. are beginning to move their start times later in the morning. However, not everyone is on the same side of these decisions. Some say that later school start times will have benefits on student performance and student health. Others say that later school start times would have negative affects on what time school will end and the schedules of the community. What times schools start is a very controversial topic.

  • Dreams and Memory Consolidation

    1298 Words  | 3 Pages

    Sleep is an extremely interesting phenomenon in which the mind almost completely departs from the usual realm of consciousness. It is distinguished from quiet wakefulness and a decreased ability to react to stimuli where we become less aware of our surroundings. However, it is more easily reversed than being in hibernation or a coma. It is a function that has been extensively researched by many. After all, we would not have evolved a mechanism that forces us to spend one-third of our lives sleeping unless sleep did us some good. What good does it do tough? Over the years, many theories have been proposed as to why we need sleep. The simplest is that it saves energy. An individual’s energy expenditure and demand is reduced during the day, or night, as an animalistic instinct when they are least efficient to search for food. This is also supported by the decrease of body temperature and caloric demand throughout sleep. For example, when NASA sent a robot to mars, it was programmed to shut down at night so exploration would not waste energy. This is like our bodies, as they need time to recuperate and to slow down. In addition, sleep provides an occasion for restorative functions of the brain where the body is allowed sufficient time to repair and rejuvenate itself. For example, animals that are deprived of sleep entirely lose all their immune function and will soon die in a matter of weeks. Other findings have shown that many restorative functions in the body like tissue repair, muscle growth, and growth hormone occur mainly during sleep. When people are deprived of sleep, inhibitory transmitters accumulate in the brain, interfering with attention and learning. People that are well rested will notice when their attention lapses, a...

  • Why Sleep is Crucial

    809 Words  | 2 Pages

    The brain is the most important organ in the body and without it life would not exist. In a metaphorical sense, the brain can be thought of as a master computer. Functions of the brain include physical behavior, emotion, learning capability and memory. Since the beginning of scientific exploration, the brain has been a significant area of interest and its complexity still puzzles scientists today. New research methods and advances in technology have allowed humans to understand more about the brain within the past 10 years than in the preceding centuries (Brain Basics, 2013.) Research on the role of sleep in brain functionality shows surprising promise. The amount and quality of sleep an individual receives effects learning ability and the risk of developing brain diseases such as Alzheimer’s.

    Researchers have found a way to connect sleep with education. Gary Scarpello who wrote "Lack Of Sleep Could Be Trouble For CTE Students” , did a research study with liberty mutual showed that teens had an average of 7.2 hours of sleep on school nights and 33 to 75 % of all students have sleep problems. In the article it had stated that not getting enough sleep can cause impaired hand eyed coordination, reaction time and brief mental lapses. (Scarpello). The same researchers also found out that Sleep helps restores brain functions such as alertness, metabolism, and memory and regulate hormones (Scarpello). Researchers Mary A. Carskardon and A.R.

  • The Effects of Sleep Deprivation on Brain and Behavior

    1930 Words  | 4 Pages

    Sleep deprivation is a commonplace occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they once did this belief is false (1). Sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally. After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly effecting a person's behavior. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting. This could involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain, especially the cerebral cortex, is not able to rest but rather remains semi-alert in a state of "quiet readiness" (2). Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior have been tested with relation to the presence of activity in different sections of the cerebral cortex.

  • Sleep Deprivation Among College Students

    If all of these important activities occur during sleep, why is it that people are so willing to short themselves of this vital activity? Although much about sleep still remains a mystery, research and experiments continue to show how important sleep is to each and every person. Throughout this paper, I will discuss sleep and the effects that it has on performance and health, especially among college students. A college student’s sleeping pattern is a reliable indicator of their level of performance in the classroom and other school-affiliated activities, as a lack of sleep leads to decreased performance. Sleep is directly related to the level of performance and health of an individual; the more rested a person is, the better that person will perform and feel (Dryer, 2006).

  • Sleep and The Effect It Has On Academic Performance

    676 Words  | 2 Pages

    Introduction Sleep studies have been conducted since as early as 1913. However, the impact of school start times on student academics is often overlooked by most schools. In reality, start times can significantly affect academic performance by disrupting adolescents' normal sleep cycle, leading to a lack of sleep that impairs learning, and hindering academic performance. These theories have been tested through sleep studies, and most of them have been found to be true. Sleep Cycle Changes When children transition from primary school to middle or high school, it can significantly affect their learning due to changes in their sleep cycle.

  • Sleep and Its Effect on Learning

    834 Words  | 2 Pages

    Sleep is a reversible, repetitive, and active behavior which plays different roles. These roles include restoration processes, memory consolidation, learning or growth. As argued out by Curcio, Ferrara and De Gennaro (2006), during sleep, neuro-cognitive, psychological, as well as behavioral processes take place. Many individuals sacrifice their sleep with an aim of carrying out extra activities. However, sleep loss has been found to have various negative effects. Some of these effects include impairment in psychomotor, neurocognitive performances, and sleepiness (Curcio et al., 2006). Results from recent studies have demonstrated that sleep plays an integral role in memory consideration and learning processes (Deregnaucourt et al., 2005 & Curcio et al., 2006). This paper will evaluate journals and other accredited sources of information in an effort to review, analyze, critique and synthesize works of other scholars on how sleep affects learning.

  • Essay On Why Kids Should Start Later In School

    2061 Words  | 5 Pages

    The alarm goes off at six am and the typical high school student is barely able to open their eyes. It is time to get up and prepare for a full day at school, about eight hours. Most teenagers, according to the National Sleep Foundation, will only get about six hours of sleep since they tend to stay up until midnight (“Should schools start later in the day?”). After getting ready, many students look forward to a nap in their first hour class despite the information they will miss. Teenagers seem to always have had trouble getting up in the morning, even earning the title of lazy from their parents. However, recent research on adolescent sleep patterns has produced a biological explanation for this tendency. This raises a serious question: why are high schools starting early in the morning when teenagers are biologically programmed to sleep in? For most cases, school start time has not been conformed to fit student physiological needs simply because of transportation issues.
