Stressing about an approaching deadline or an upcoming test is nothing new to most people, especially students. The manner in which both business professionals and students handle the stress is quite similar. The majority of people who often find themselves in this situation say that they stay up most of the night, if not all the night, preparing and reviewing information. As the standards for a quality education continue to increase rapidly, students find themselves having less and less time to prepare for approaching exam dates. The pressure to succeed and do well causes many high school and college students to study all the information intensively, or cram, the night before the exam while putting off sleep. Although this seems harmless, there are many severe effects to late night study sessions. Staying up late and reviewing information does more harm than good.
First, there is no correlation between late night studying and doing better on exams. In fact, research shows the exact opposite. Studies have shown that “the information will not sink in, because memories form during deep sleep” (“Cramming hurts grades and health”, 2012). By the time of the test, the information will no longer be remembered. It would be similar to not studying at all. Making late night caffeine filled study sessions pointless and ineffective.
Giving up sleep for grades may seem like a good idea; however, cramming for an exam the night before actually impairs mental function. “Harvard Medical School associate professor Seung-Schik Yoo drew this conclusion after doing a study that required subjects to forgo sleep for 36 hours and evaluate various visual stimuli” (Heibutzki). Yoo’s study showed that sleep deprivation can weaken mental function. Those wh...

Sleep loss and shifting sleep patterns are known to be widespread across college campuses throughout the United States and the world at large. Yet, while many studies exist relating sleep to performance, a much smaller amount of studies focus on the Through analysis of these sources as they would prove useful when researching and writing upon the idea of sleep and its correlation to academic performance it was found that a paper titled “Sleep-Wake Patterns and Academic Performance in University Students”, which was presented to the European Conference on Educational Research, is overall the most useful source represented to research the topic.
This is also proven by a study, which shows that students who perform worse on their exams seem to be more stressed and suffer from poor sleep quality (Ahrberg, Dresler, Niedermaier, Steiger, & Genzel, 2012). For instance, student A is a freshman at Ball State University. This student only sleeps for 6 hours because of bad sleeping habits and later on he sleeps for only 4 hours because of the new environment which has many factors that affect his sleep schedule such as social life, school activities or extracurricular activities. Then sleep deprivation is starting to affect him. He have a test the next day and studied the whole night and only slept for 2 hours. The next day, while he was having the test, he started to feel very tired, sleepy and stressed. He couldn’t concentrate on the test so he failed the test. He started to feel more stressed because of bad grades which might make him take the course again. He couldn’t sleep for more than 4 hours and these bad cycle repeats. Moreover, high stress could also affect the emotion of the students. It can also cause depression which can significantly decrease the academic performance and grade point average of a student. Stress caused by sleep deprivation can really have a big effect on
Many times people think they can accomplish more if they could eliminate so much sleeping time. However, they are only hurting their productivity if they lose sleep. Two articles deal with the issue of sleep deprivation. The College Student Journal published an article about the grade-point average of college students and sleep length, while U.S. News & World Report produced an article dealing with the lack of
Austin states that most students manage to “get less sleep during weekdays and more sleep on weekends to pay back the sleep debt” (36). But this sleep pattern is not what the body is used to during the week and actually affects the student more than he or she thinks. The pattern of sleep the student chooses to have on the weekends makes it difficult to rise each morning for early classes, and it increases his or her sleepiness throughout the week (Austin 36). While each student thinks sleeping more on the weekends benefits them, it actually hurts them because it makes their sleep patterns irregular. When this happens it makes the week harder to deal with because everything is out of
The typical college course requires the successful completion of challenging assignments, such as exams, term papers, and presentations. With deadlines looming for these assignments, some students will begin their work right away, while others will wait until the last minute to get started. While research evidence does not support the utility of last-minute strategies, such as cramming for exams, students may nonetheless engage in these behaviors as a result of procrastination (Schraw, Wadkins, & Olafson, 2007; Senecal, Koestner, & Vallerand, 1995). For active procrastinators, their act could lead to positive outcomes, such as high grades,
While in both essays Sleep Duration and Cognitive Performance in Adolescence and Understanding Adolescents’ Sleep Pattern and School Performance: a Critical Appraisal, researchers have ended up with statements that confirm the positive relationship between sleep and academic performance, though the latter with part disagreement, in another essay Association of Sleep and Academic Performance, the findings were different. The research shows that the amount of sleep has no apparent effect on the students’ academic performances.
As the saying goes too much of a good thing is bad, so so maybe that could be one thing with studying. Yes, we all know that studying is a key part of making good grades but maybe staying too much is also a bad thing. “During REM. Sleep - A period of deep sleep that happens 3 to 5 times a night and well rest people - the brain is wildly active sorting and categorizing the days data. More sleep you get the better the information is absorbed”(Hoofman 12). So it is vital that we get enough sleep to be able to categorize what we have learned throughout the day at school. In a article it reads out “ the later first period begins, the higher distribution of students grade”( “Impact of school”). If our school really wants be one the best in the country and have the most outstanding scores, why not start school at a later
...udy a little bit each night instead if you want to receive good test scores; if you study earlier in the day but cram during that time, you will still receive test scores that are just as good as those who study a bit each day because you are not neglecting any sleep.
Research shows that sleep is a necessity in order for someone to be able to perform at their maximum potential. College students are no exception to the rule and are often at a greater risk to suffer from conditions that accompany sleep deprivation. Regardless of the time period, a college student must be well rested in order to perform at his or her best in terms of physical performance, memorization capabilities, and test-taking abilities. Also, without adequate sleep, the person will be more susceptible to illnesses, both mental and physical. In conclusion, I believe that sleep deprivation among college students is extremely common and has a direct effect on how well that student will perform or feel.
According to the National Sleep Foundation, 33% of high school students fall asleep during school. Most people claim that the students being tired is due to them simply staying up too late, but that is not always the case. The way that the school start times are set up, now it is nearly impossible to get the amount of sleep that students need to function. With the biological sleep clock of students having them fall asleep at 11:00pm and then having to be up at 6:00 in the morning to get ready, the ten-hour goal is unachievable.When students are sleep deprived their focus and attention drift more easily making it significantly harder to pay attention in class. The lack of sleep also impacts students memory, the brain has to work harder to be able to retrieve previously learned information (Sleep, Learning, and Memory). Students who have gotten a good night rest are proven to pay more attention in
According to Danny Lewin, a sleep specialist at Children’s National Health System in Washington D.C. “Adolescents have a deeply programmed biological [clock] to go to bed later and wake later.” This shows that kids naturally stay up late and wake up later. From personal experience, not too long ago I was at a track meet in Dayton, by the time our Sheridan team got back it was 11:00 pm and we were tired. The next day I’m really tired, and struggling to keep myself awake. Our growing bodies need sleep to function properly. Students are going to start feeling tired and lazy. More sleep means everything to the students, especially because of our “deeply programmed biological
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 has always been a popular subject among humans. There have been many studies that examine sleep and its correlation with a wide variety of variables, such as depression, energy levels, and grades. Students, as a group, are widely studied. As the world’s future leaders and thinkers, there is great importance placed on their achievements. In this study the effect of student sleep habits on perceived academic performance is investigated. Many things may affect students’ academic success among these variables are sleep habits.
Sleep plays a vital role in a person’s mental well-being. Sleeping affects how well people think, react, work, learn, and get along with others. While a person is sleeping, his brain is preparing to help him learn and remember information. A good night’s sleep enhances learning and problem solving skills. It is very important for the students to have sound sleep as it can improve their concentration, memory and creativity. Furthermore, having enough sleep increases the ability to m...
Sleep deficiency impairs the neurocognitive functioning and prevents proper retention of information by the brain. Moreover, inadequate sleep at night diminishes attention span, alertness, creativity and concentration levels of the students. According to Curcio, Ferrara & De Gennaro (2006) students with more regular sleep-wake cycles are more likely to report a higher GPA (p. 326). Finally, I will explain how sleep-disordered breathing caused due to sleep deprivation, may also be associated with poor academic achievement and neurocognitive impairments such as critical thinking and
