Sleep is necessary to function in everyday life. Without sleep, humans become impaired, and simple day-to-day activities become harder to do. Sleep deprivation is increasing steadily among the human population as some humans strive to prolong the time that they are awake believing that sleeping is a waste of time. However, studies show that sleep is necessary for the body to process the information taken in that day and store that information. Sleep deprivation has several effects on the human body, and not only can it impair our ability to learn and retain information, it also increases our risk for attaining certain diseases and health problems. It is a common misconception that naps can set back the effects of sleep deprivation. However, …show more content…
The data I collected shows a correlation in the amount of time a nap takes and the energy level of the student after they have taken the nap. I found that if the nap is less than forty five minutes long the person will usually wake up feeling refreshed and alert. If the nap is longer than forty five minutes the students reported feeling groggy and disoriented. I found through extensive research that what these students feel is called sleep inertia. Sleep inertia is a feeling of grogginess due to your body still believing it is asleep (Healthy Sleep). This usually happens as a result of people taking long naps and waking up instead of actually going to sleep. The longer a nap actually is the more the body thinks it is actually going to go to sleep because it pulls the person “napping” into a deeper state of sleeping where the effects of REM sleep start taking place. REM sleep, rapid eye movement, is where the body systems become active like the brain while the muscle of the body become paralyzed. The body has not entered REM sleep but it is preparing to do so (Healthy Sleep). Which is why napping for more than forty five minutes is ineffective if the student wants to momentary boost of cognitive performance. What the student actually does by taking a forty five minute nap or more is cause sleep inertia that can last several minutes making the nap counterproductive. In regards to the productivity naps can offer my findings concur with Dr. Driskell and his research, "The Efficacy of Naps as a Fatigue Countermeasure: A Meta-Analytic Integration", which address the use of naps as a counterbalance to the side effect, fatigue, that comes from sleep deprivation. However, the only difference is that my research targets sleep deprivation as a whole instead of just one side effect. Regardless in both cases the
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.
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...
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 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).
By side by side computer noticing the different degrees of sleeping, and fatigue checklist of recording with the mood scale. After twenty-four hours without sleep, her performance and the mood was in the worst status, the level of fatigue on the high level. Now she recorded that she find herself in the space, there was nothing in her mind everything was blanked. Between 4:00 to 6:00 am after first night according to researcher participants have hit the lowest point but according to Dotto this is very depressive because she was tired only at that time. Now whenever the research announced about the nap time it was not the …… moment for her. But after the nap of about one and half hour, she feels refresh and able to reset her mind on the tasks. Due to this her logical reasoning and serial reaction performance improved by forty percent or it are nearly equal to the started experiment performances. The research basically base upon to knowing the effect of napping on performance. In the last it can be concluded by the researcher that for the professional workers it is very important to always get in the high level of alertness so for these napping is the
Taken as a whole, each state of sleep, REM and non-REM plays a crucial role in memory and learning. Without it our brains would not be given the opportunity to consolidate new ideas and concepts learned throughout the days and even years. Many studies have shown that sleep is directly correlated with learning through similar brain functions activated while animals and people were both awake and asleep. If the proper amount of sleep is not allowed, sleep deprivation will impair brain functionality. This will create problems with neuron performance in areas such as the cerebral cortex, thus causing impairment in judgment, behavior, focus, memory and learning. Overall, it is clear that a good night’s sleep plays a vital role in learning and memory.
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.
Sleeping is something that is an essential part of human nature and is a must in order for one to be a functional human being. Sleep is an idea that is accompanied by many wives’ tales, including the ideas that one needs seven to eight hours of sleep each night and alcohol helps one fall asleep and sleep more soundly. One myth about sleep is that during sleeping, one is in a state of nothingness. In truth, however, it has been discovered that during sleep the brain is active, variations in heartbeat and breathing occur, and the eyes and ears are active throughout the time of sleep. These activities during a person’s sleep are important because they help that person be more aware, awake, and alert during consciousness. 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 in college students. A college student’s sleeping pattern is a reliable indicator to 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 the level of performance and health in an individual; the more rested a person is, the better that person will perform and feel (Dryer, 2006).
Each night, the average person spends approximately 7-9 hours giving their bodies a restful vacation in the land of dreams. Considering this, we spend 1/3 (or 25 years) of our entire lives engaging in this idle activity. Although these numbers can appear as a waste of time in our every day lives, sleeping and/or napping is the energy that helps fuel our bodies to function correctly. Sleep is a necessary function in our every day routine in order to make our brains function at the most efficient level. As we sleep, the brain helps us to recuperate and regain strength by “restoring and repairing the brain tissue” (Myers, 2010, p 99). Without this reviving process, we would all eventually deteriorate. By impairing the sleep deprived mentally and physically, it can potentially cause serious harm. We must fade our conscious mind, and let our mind relax within subconscious state.
In conclusion, the moderately enhanced results leads to think that the naps did have positive effects on all three test results, but not to the extend that was hypothesized. Perhaps a more ordered and organized napping and sleep schedule would allow for greater and more significant improvements. A further analysis in the domain of effects of napping on performance, either cognitive or physical, should strive to measure the impact of tightly arranged schedule to allow for naps to occur at relatively the same time everyday, as well as having a similar length, paired with comparable amount of sleep the night prior to engaging in napping. This would allow assessing the true effects of naps on an individual much more effectively.
However, this is simply not so. Productivity lags among sleep deprived workers, so abstaining from a nap would be a net loss, as individuals would be forced to slog through the rest of their day at a greatly reduced level of effectiveness. After a nap, even one of only 20 minutes, workers feel refreshed and ready to attack their work with renewed vigor. In the long term, this boost in energy will yield greater results than if they were to simply deny themselves the rest which they so dearly need. With innovative and advanced corporations such as Nike and Google embracing the importance of naps, they prove to be a net positive for businesses, and more companies should adopt this practice to improve their
In Source #3, the author states that “...studies show that taking a short nap after learning new information may help you remember that information better!” and “Nap lengths between 10-20 minutes have been shown to increase productivity, decrease fatigue, and improve mood.” Naps are vital to possess the ability to be at the top of your classes and have a good school year. They can recharge you a bit and help you feel more alert to do all the homework or volunteer work you could be doing but too tired to. Many students these days are not getting enough sleep, because we have to wake up early and are expected to be alert all day.
The story behind sleep deprivation is controversial depending on how it is practiced, perceived, and where it is practiced. I believe that there are norms to follow according to exigencies from each country in the world if they have integrated the SD practice in their interrogatory procedures. It is said that prisoners are the properties of the state government; however, depriving prisoners for sleeping with intend to get something out of them is inculcating harm to their body which against the ethic code. For instance, interrogation will augment stress levels in the prisoner, augmenting the chances that interrogators might divulge important information (Alison, n.d.). It is alright if the prisoner’ state of health is not endangered.
Sleep is a very important factor in the human function. Our body and brain is able to reset itself and rejuvenate while we sleep. When we do not get the required amount of sleep, we start to feel lethargic and foggy minded, because our mind and body wasn’t able to replenish itself. Sleep is imperative that an insignificant rest deficiency or lack of sleep can affect our ability to remember things; decisions and can affect our temperament. Chronic sleep deficiency can get the body to feel agitated and it could lead to serious health problems such as, heart problems, stress, acne, and obesity.
Preliminary Thesis Statement: Sleep deprivation has detrimental effects on the health and academic performance of students.
