The one-third of our lives that we spend sleeping, far from being “unproductive,” plays a direct role in how full, energetic and successful the other two-thirds of our lives can be” (Why Do We).
Sleep: A natural, periodically recurring physiological sate of rest for the mind and body marked by relative physical and nervous inactivity, complete or partial loss of consciousness and lessened responsiveness to external stimuli. (Sleep 1062)
“Sleep seems like a perfectly fine waste of time,” mocks Maria Konnikova, writer for the New York Times. “Why would our bodies evolve to spend close to one-third of our lives completely out of it, when we could instead be doing something useful or exciting” (Konnikova)? Most people view sleep as simply “going to bed,” then “waking up,” and as though there’s no in-between. What about when one is asleep; being aware of what happens within sleep, understanding unhealthy sleep, knowing what can go wrong, and how to be the healthiest sleeper, is all very important. Though some may view sleeping as a waste of time, life is nothing without sleep.
Claudio Stampi, a doctor with a specialized degree in neurology from the University of Bologna in Italy writes in his book “Why We Nap,” that “phasic [phasic sleeping] behavior is divided into two major categories: polyphasic and monophasic” (2). Subcategories of polyphasic sleep are Pure Polyphasic, Quasi-Polyphasic, and Semi Polyphasic sleep. In Pure Polyphasic sleep, episodes of sleep and activity are evenly distributed in contrast to Quasi-Polyphasic sleep which is not evenly distributed throughout a twenty-four hour period. In Semipolyphasic patterns, sleeping consists of one large increment of time, as well as several other small increments. Stampi con...

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 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...
Getting sufficient sleep is a basic human need and is vital for life. According to Maslow’s hierarchy of needs, sleep is a high priority for survival. Having enough sleep is therefore important to restore body and brain functions, preserve energy, maintain general well-being and prevent illnesses.
Around 40 million (Sleeping Disorder Statistics, 2012) Americans suffer from chronic sleeping disorders, regardless of their age. Some common disorders are insomnia, narcolepsy, and sleep apnea. Individuals who suffer from insomnia have a difficult time falling asleep and staying asleep, resulting...
Attention Grabber. Sleep is both a biological and natural need, just like food and water. Without obtaining the necessary amount of sleep the human body needs to be able to function the human mind and body would be chaotic. In order for you to maintain an healthy lifestyle you need an appropriate amount of sleep amongst other things. Sleep is important because it affects behavior, learning, mood, and memory. Furthermore, during sleep tissue growth and repairs occur, hormones are released, energy is restored to the body, and energy is also provided to the brain and body. This reveals that sleep has a profound importance towards the health of humans, when the regulated amount that you are suppose to receive is tampered with it can lead to an increase in stress, lack of alertness, and potentially life endangering consequences.
Sleep is a necessary, regularly repeating occurrence of rest defined by decreased motion, decreased consciousness, and distinguishing stages of activity in the brain. (189)
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).
While points, claims, and statistics may be found within all of the sources used for the research, the sheer amount of referenced studies and works within the “Sleep-Wake” paper lends weight to it’s usefulness as a reliable source. One of the otherfactor of sleep and its affect within the college community. Three sources varying in criteria and usefulness were found that related to this subject and were studied. sources, “College Students try to Cheat Sleep Needs”, a college newspaper, offers basic facts and elementary assumptions such that could be found within any biology textbook or encyclopedia. These references are to such things as sleep cycles and sub stages and the general consequences of an out of balance sleep cycle. The study from the Biological Rhythm Research writers, however, hints at previous studies and findings that “several factors, such as social and academic demands, part-time jobs, [...] affect the sleep-wake cycle of college students.” but then only states the findings of a particular study, and does so in...

the sleeper will gradually descend deeper into sleep, becoming more and more detached from the outside world and progressively more difficult to awaken. Stage three is the beginning of deep sleep, occurring about thirty to forty five minutes after you first fall asleep. The deepest sleep occurs in Stage four. Stage three and four has the biggest and slowest brain wave. REM sleep, a mentally active period during which dreaming occurs, provided a biological explanation for this phenomenon. Scientists found that brain activity during REM sleep begins in the pons, a structure in the brainstem, and neighboring midbrain regions. The pons sends signals to the thalamus and to the cerebral cortex, which is responsible for most thought processes. There are several myths about sleep. For one, how much sleep a person should get? According to our text book people should sleep for at least eight hours to maintain sound mental and physical health. But every one doesn’t get the chance to sleep for that amount of time. There is no normal amount of time you should sleep. Everyone is not the same. For one I might sleep for five hours and feel refreshed enough to work another shift. Other hand my cousin might need more then eight hours of sleep to feel refreshed.
Central idea : Sleep is vital to our health and well-being throughout our life, therefore, in order to protect our mental and physical health, quality of life, and safety, we must get an enough quality sleep at the right times.
Important public policy issues have arisen in our modern 24-hour society, where it is crucial to weigh the value of sleep versus wakefulness. Scientific knowledge about sleep is currently insufficient to resolve the political and academic debates raging about how much and when people should sleep. These issues affect almost everybody, from the shift worker to the international traveler, from the physician to the policy maker, from the anthropologist to the student preparing for an exam.

Sleep is very important for human beings. Sleeping means taking rest for every person and each person spends one-third of his lifetime sleeping. Without sleeping, no one can exist in this world. Sleeping is essential for a person’s health and well-being throughout his life. Getting enough quality sleep at the right times helps all people protect their mental health, physical health and safety. A person who does not get enough sleep might suffer from mental disorders, diseases and even harmful situations. Therefore, it is important for every human being to have enough sleep.
