To define sleep, we could say that it is a process of renewal for the body. Scientists still don't have an explanation for why we should sleep, but for sure they know that sleep is not 'switch off' case for the body. They know that the sleep is an essential for many physiological processes, as consolidation of memories. On average, people spend a third of their lives in sleep and that is an evidence for the importance of sleep for us. There are many explanations for sleeping process and what is happening to us during it, but most of them are spiritual and religious explanations. In these days, the scientists start to research the topic. And now, they can tell us what is happening to us during sleep scientifically, despite the opposite who refuse the scientific explanation. …show more content…
Throughout history, humanity has so many explanations for dreaming process, but most of them are religious and spiritual. However, the scientists said that "dream production mechanisms draw bits and pieces of elements within the vast mnemonic repertoire that contains all the information, knowledge, and personal memories accumulated over an entire lifetime"(Grenier et al., 2005, p 280). Anything we see in our dreams is already inside our brains, maybe for a long time that we can't remember it. When we are dreaming, our memories, which contain everything we experienced in our whole life, became an "open book" for us to catch memories and feeling from here and there and combine them to create the dreams. So, when you see your dead grandfather that doesn't mean his soul is visiting you, it means that he is still within your memories and your mind catch that memory and changes it into a
Rather than normal sleep, scientists decided they were in what is called REM sleep. During REM sleep, also known as rapid eye movement, is when one become sexually aroused, one becomes limp, eyes moved around, heart break and breathing
With exceptional haste we begin to recite our knowledge of the human mind. As is stated in The Twenty-Four Hour Mind by Rosalind D. Cartwright, sleep allows our brain to consolidate our experiences and memories of the day (Cartwright 30) while we lay in a semi-vegetative state (Cartwright iix). The consequences of lack of sleep are evident in studies performed on individuals who suffer from insomnia. In “Sleep in the Workplace: What the Psychologist-Manager Should Know About Sleep”, the article highlights the cognitive effects that lack of sleep can have on an individual including impaired working memory, learning capability, and decision-making (Gaulltney & Collins-McNeil 135). Our rational mind dismisses Murakami’s obvious fictional short story and dismounts every claim that a human could survive without sleep.
One of the most common brain activities during sleep is dreaming. Scientist still to this day do not fully understand why we dream or what dreams are exactly. “Some experts suggest that dreams represent the replay of the day’s events as a critical mechanism in the formation of memories, while others claim that the content in dreams is simply the result of random activity in the brain.” It is known that visually intense dreaming occurs most commonly in the REM sleep stage. Dreaming causes the brain to become very active, and not only at displaying the images we see during our dreams.
Sleepless in American is a National Geographic documentary on the lack of sleep Americans are receiving each night. The film starts with the statistic that “40% of American adults are sleep deprived” and followed with different effects of sleep deprivation such as: weight gain, delayed reaction time, depression, anxiety, speeds the growth of cancer, and has been linked to Alzheimer’s disease. Although, there is no scientific evidence to support the need for sleep, it is an important process that allows our bodies to function properly. Several sleep studies have been performed to understand the effects sleep deprivation has on a person. The participants of the sleep trial only received four hours of sleep per night.
He explains that some animals are very vulnerable when they sleep and it is instinctual that they sleep in caves or burrows to keep them safe while they rest and regenerate and it is the same for humans we usually return home and when night comes we rest in our safe environment. He also says that sleep was naturally selected and maintained by selective pressure. (Flanagan
1. Introduction Starting from the ancient times humans has always been interested in strange phenomena of sleeping and dreams. Dreams can be explained psychologically as images of subconsciousness and feedback of neural processes in human's brain. For most of us, dreaming is something quite separate from normal life. When we wake up from being chased by a monster, or being on a date with a movie star, we realize with relief or disappointment that "it was just a dream."
It was strange to discover that some scholars argue that sleep is frivolous and is trying to find ways to eliminate it altogether while maintaining an optimal level of functioning and efficiency. However, Ratey and Manning believe sleep, and good sleep at that, makes us more productive and efficient beings. The topic is not so much about sleep itself as it is how we sleep. Studies show that married people and people who sleep with animals live longer lives; the importance pointing to the feeling of safety in numbers. Light is also a major factor the effects sleep.

As a matter of fact, we usually don’t pay much attention to the quality of our sleep, in spite of influencing a big deal our performance during the day, our health and well-being, in other words, our quality of life. That’s the reason why I would like to introduce some interesting material to understand better this important though disregarded necessity.
For every two hours that our brains are learning daily, it needs an hour of sleep to comprehend its meaning. Stickgold states, if you don’t sleep, you die (Ratey & Manning, 2004, p.126 ). This statement had a great impact on my thoughts of sleep and death being the result. Sleep is necessary for bodily function, learning absorption, and cognition for daily living and safety. Eight and a half hours per night every twenty-four hours is recommended otherwise the person is not sleeping enough.
