Recommended: Effect of school start times on academic performance

hysical Health Benefits of Delaying School Start Times According to a poll conducted by The National Sleep Foundation (NSF) (2011), a nonprofit organization directed by doctors from Stanford, Clayton and John Hopkins University, at least 60% of students reported being tired during the day and 15% stated they had fallen asleep during school that year. The NSF also found that 59% of sixth through eighth grade students and 87% of the high school population in the United States were receiving less than the recommended amount of sleeping hours on school nights. Due to the current school start times in America, it has become difficult for students to obtain the necessary eight hours of sleep recommended by the Stanford Medical Center and American …show more content…

Research examiners of the FASEB Journal (1996), a scientific journal promoting scientific progress and education, performed a study consisting of 120 individuals. The participants were only permitted to obtain 4 hours of sleep, making them sleep deprived. The effects of the loss of sleep in the participants were clear. The sleep deprivation caused a decrease in the number of natural killer (NK) cells, which are cells that play a critical role in bacteria-rejection of the immune system. By impacting the overall effectiveness of the immune system, the body had become weaker and was not able to fight off viruses such as the common cold or a sore throat. Due to the inadequate amount of sleep acquired, the normal processes of the immune system had been …show more content…

The researchers compared two groups of participants; sleep deprived and non sleep deprived. The group of non sleep deprived individuals gained eight and half to ten hours of sleep, while the sleep deprived group only acquired two and half to four hours of sleep. Both of the control groups were given the influenza shot, the flu vaccine. The executive researchers determined and compared the effectiveness of the vaccine in each of the groups. Individuals who had been deprived of sleep were 47% more immune to the influenza vaccine, AAA (2005). For the same reason as the study conducted by the FASEB Journal, the NK cells had been weakened and were unable to process the vaccine due to the harmful amounts of sleep being obtained. The FASEB Journal and American Academy of Allergy, Asthma and Immunology selectively analyze the detrimental effects sleep loss can potentially have on the immune system. Sleep deprivation directly weakened the host-fighting cells of the immune system (NK) and their ability to process vaccines such as influenza. By allowing students the ability to gain the recommended amount of sleep, the physical health of the students will be greatly assisted by reducing the risk of obesity in and strengthening the immune

  • The Effects of Sleep Deprivation on Brain and Behavior

    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 is one of our basic needs to survive and to function in day to day operations, but not everyone needs the same amount of sleep. Some people can survive on very little sleep, i.e. five hours a night, and some people need a lot of sleep, to the extend that they are sleeping up to 10 to sometimes 15 hours a night (Nature, 2005). According to Wilson (2005) the general rule states that most people need from seven to eight hours of sleep. The deprivation of sleep in our society in continually increasing with the demands in society increasing work loads, the myth that a few hours of sleep is only necessary to function properly and that sleep is sometimes considered as killing time (Nature, 2005). Sometimes sleep deprivation is also caused by other situations like sleep disorders, i.e. sleep apnea, chronic insomnia or medical conditions such as stress (Wilson, 2005).

  • Sleep: The Immune System And The Immune System

    728 Words  | 2 Pages

    Due to this down regulation, a subsequent decrease in cortisol, epinephrine, and norepinephrine occurs, which contributes to suppressed immune functions. In contrast, growth hormone, prolactin, melatonin, and leptin levels increase. These molecules act as pro-inflammatory signals to activate the immune system, aid in proliferation, differentiation, and generation of pro-inflammatory cytokines, including IL-1 and TNF-α4. At the beginning of slow-wave sleep (SWS), pro-inflammatory cytokines and Th1 cytokines increase, however there remains uncertainty as to why this occurs. One theory is that over the course of wakefulness, dangerous factors accumulate in the body, including reactive oxygen species (ROS), heat shock proteins (HSP), and nucleotides. These molecules are thought to be similar to microbial molecules such as lipopolysaccharide (LPS) and other toll-like receptor ligands that enhance the production of pro-inflammatory cytokines via antigen presenting cells (APCs). Additionally, immune cells have their own internal clocks that maintain periodic changes in pro-inflammatory cytokines4. In terms of specific cytokines, IL-1 and TNF-α have both been shown to increase NREM sleep in animal studies. It is therefore intuitive that through inactivation or interference with the normal action of these two cytokines, spontaneous NREM sleep is decreased. For instance, by preventing the activation of IL-1 by cleavage of its inactive form, NREM sleep is reduced3. It is also important to note that high levels of IL-1 inhibit sleep, which could be due to a feedback loop involving corticotropin-releasing hormone (CRH) stimulation by IL-1. In terms of immune regulation, IL-1 and TNF-α induce activation of nuclear factor kappa B (NFκB), a transcription factor that has been found to be associated with substances that regulate

    Sleep deprivation is often associated with the development of medical conditions, especially cardiovascular disease (CVD). As disturbance in sleep could cause deprivation and shorten one’s sleep duration, it is often taken into account when carrying out related studies. Short-term sleep deprivation not only raises blood pressure and produces stress hormones, but also leads to irregular heartbeats [1]. These major risk factors are precursors to coronary disease. In this essay, I will summarize the findings of five studies in relation to sleep deprivation and the increased risk of CVD.

    Sleep deprivation in hospitalized patients can result in increased morbidity and mortality, and can lower their quality of life. Hospitalized patients require more than the average amount of sleep to aid in recovery, but often get an inadequate amount of sleep or experience poor quality sleep. There are increased frequencies of awakening or being awakened too early in the morning, difficulty falling asleep, an increased need for sleep medications, poor sleep quality, an increase in frequency of napping and nightmares. Sleep-wake cycles contribute to adequate protein synthesis and cellular division that is crucial to sustaining the healing process and maintaining immunity.

    My paper is based on an article from the text’s web site (chapter 9) entitled “Lack of sleep ages body’s systems.” The basic claim of the article is that sleep deprivation has various harmful effects on the body. The reported effects include decreased ability to metabolize glucose (similar to what occurs in diabetes) and increased levels of cortisol (a stress hormone involved in memory and regulation of blood sugar levels). The article also briefly alludes (in the quote at the bottom of page 1) to unspecified changes in brain and immune functioning with sleep deprivation.

    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).

    According to Dr. Judith Owens, director of the Sleep Medicine Clinic at Children's National Medical Center in Washington, D.C., "adolescents are programmed to fall asleep later" (2013). She advocates for later school start times because "we are asking [teens] to be awake and alert at the time in their 24-hour clock when their alertness level is at its very lowest" (2013). Additionally, most teens cannot fall asleep until 11 p.m. Sleep expert Amy Wolfson of the College of the Holy Cross in Worcester, Mass., recommends that children aim for eight and a half to nine and a half hours of sleep per night. Waking up at 6 a.m. can disrupt sleep patterns and lead to sleep deprivation. A new poll conducted by NPR, the Robert Wood Johnson Foundation, and the Harvard School of Public Health has revealed that 50 percent of high school students report starting school at 8 a.m. or earlier....

    At first, people's eyes begin to feel dry and they have trouble concentrating, causing their eyesight to weaken. Their reaction time slows down as well as their thinking process and judgment. These effects are minor but as one’s body weakens, their immune system is affected as well. This may cause their body to catch an illness or disease. Afterwards, their body becomes very weak and it will take a while before it can heal properly. In addition, their heart gets tired and cannot perform its job properly, so prolonged sleep deprivation also leads to risk of heart diseases. Not only does sleep loss make people feel tired, but it is also harmful to their body by increasing the risk of health problems (“Sleep Deprivation: What Are the Physical Effects” , Griffin R.

    Fifty six percent of students report being tired throughout the school day, which can lead to missed information and confusion (Wysong). According to this statistic, over half the students in class are not going to achieve their maximum learning potential in school. In order to avoid this problem, a teenager's brain typically needs to sleep from 11:00 pm to 8:00 am (“High schools starting later to help sleepy teens”). However, most high schools require students to be in class as early as 7:15 or 7:30 am. As a result, many adolescents simply do not have the opportunity to get enough rest. Changing the traditional school time to start later in the day will benefit adolescent sleep cycles, promote learning, and prevent disease by regulating the body. Ideally,...
