BOOK REVIEW Review of The Twenty-four Hour Mind: The Role of Sleep and Dreaming in Our Emotional Lives by Rosalind Cartwright 224 pages Oxford University Press, USA; * edition (June 24, 2010) Patrick McNamara, Ph.D. T his is a book of many virtues. It gives us an insider look at the birth of the sleep medicine specialty. It provides, in clear entertaining, first person-prose a first rate primer on the latest {"indings in sleep science. It speaks with the voice of a mature, humane, sane, and brilliant clinician. Most impressively it lays out in convincing detail the argument for the theory of the 24 mind. That theory, as I understand it, suggests that selected regions of the mind/brain are active and functional 24 hours a day. The …show more content…
After pushing the body into the pool Falater apparently went back into the house. Cartwright thinks Ealater went back into the house to go back to bed/sleep, just as most other sleepwalkers do unless they are awakened by a loud sound. The police called to the scene by the neighbor found Falater coming down the stairs from the bedroom and the body floating in the pool. One pities this family, especially the teenage children who were apparently asleep when all this happened but awoke to the father being led away in handcuffs and their mother brutally murdered. Falater was convicted of murder despite the defense's claim that the defendant has been sleepwalking. In the years that he has been in jail Falater sent Cartwright many of his dreams which she reproduces (with his permission) in an appendix of the book. The neuro-psychologic conditions under which this sort of violent tragedy can occur are laid out and extensively discussed by Cartwright. All apply to the Falater case. There is usually a Stressor in the patient's life that disrupts sleep. There is usually a history of sleepwalking and a family vulnerability to the disorder. The parasomnia usually occurs in the first part of the night in a NREM stage. After the event the patient is utterly amnestic for the episode and attempts no cover-up of the deed. There is grief, remorse and efforts to cooperate in the investigation. Cartwright sees it as an obligation of the scientist that when he or she has
Sleeping disorder is a medical disorder of the sleep models of a human being or an animal. The sleeping disorders interfere with the normal mental, physical, social, and emotional functioning of the body. The commonly ordered sleeping disorders are polysomnography and actigraphy. This paper provides a critical analysis of a 2010 article written by Jane F. Gaultney called The prevalence of sleep disorders in college students: impact on academic performance.
In my paper, I will tackle insomnia from various perspectives: definitions, types, causes, effects, and means of solutions.
I’ve been thinking about sleep ever since reading Maria Konnikova’s fascinating, three-part series for The New Yorker on sleep. And then my wife, Crystal, read the series, which got us both thinking about it, and talking about it, and experimenting with it.
I did not sleep well as a child. When I closed my eyes, I was not inundated with calming thoughts, nor fantastical images, but rather assaulted by existential anxieties which coaxed me into undesired ruminations about my being. I believed falling asleep was tantamount to relinquishing control over my ephemeral existence, as there was no guarantee of awakening. I found myself clinging to the present to the detriment of the future, desperately eschewing its hastened arrival for fear that it would not include me in its progression. And yet, every night, hour by hour, I would find myself succumbing to the physical and mental manifestations of sleep deprivation. I would come to plead for the very loss of control that I so viscerally feared, as
Sleep deprivation is a serious concern among college students, who are "among the most sleep-deprived age group in the United States," (Central Michigan University, 2008). It is important to study the causes of sleep deprivation, or sleep disorders, among college students. According to Park (2009), "dozens of studies have linked an increase in nightly sleep to better cognition and alertness." A study by Central Michigan University (2008) found that sleep deprivation can lead to poor academic performance, impaired driving, depression, and behavioral problems. There are several variables that may affect sleeping patterns among college students. One is genetics or biological issues. It is highly
The sleep assessment conducted on the patient had an interesting dynamic in how we think we sleep opposed to how our partner says we sleep. The patient wakes up every morning at 6 a.m. and takes a nap right after lunchtime approximately at 1 p.m. The daily naps, according to the patient, last about forty-five minutes to an hour. When asked about restlessness when waking up the patient with a stern voice and pointed finger says, "When I'm up I'm up and ready to go." The patient also explained that they have no trouble staying asleep; however going to sleep can be challenging depending on if anything troubling is on her mind.
Not many courses introduce the idea of sleep, so it had only been a side interest. I was unaware of the seriousness of the problem and only wanted to understand sleep disorders because I’ve dealt with insomnia myself. Not until college did it occur to me that sleep was serious enough that studying sleep was a profession. However, school has only taught me the minimal basics of sleep. I wanted to understand the mechanism, the consequences, and the treatments for sleep. Unable to get a better idea of sleep, I aimed to learn more about sleep research. Eventually through graduate research, I would like to focus on understanding sleep and its application in improving health.
This essay focuses on evaluating three functions of sleep. These functions include mental health (Jackowska et al, 2011), cardiovascular disease (Kronholm et al, 2011) and memory (Hu et al, 2006). The key aspects are explained in detail with regards to studies. The findings from the studies will help justify the function and it’s involvement with sleep. Sleep is important for an individual’s well being, survival, brain development, emotional regulation, cognitive function, memory, and in order to protect mental and cardiovascular health. An individual should sleep for 6-8 hours. A recent suggestion by the American Academy of Sleep Medicine recommended that an individual should sleep for minimum 7 hours. The quality of sleep is significant to maintain healthy brain functions. Evidence, indicating that good sleep quality is essential for mood and health then duration (Chandola et al, 2010). The researches implied will enable the understanding of the functions of sleep and evaluate the evidence of each of the functions, including advantages and limitations. Furthermore ethical issues are discussed, and an overall summary of the essay is briefed.
Success in life is typically measured by the result of what is accomplished during the waking hours. The degree of effectiveness of those hours however, depend on effective rest. “Sleep is integral to the health and well-being of all people” (Wells 233). Sleep is simply defined as the body’s rest cycle – a time to recharge. The widely accepted metric for normal or sufficient sleep is about 8 hours of uninterrupted sleep. When this metric is not met, either through total sleep loss or accumulated sleep debt, the effect can be dire, “Sleep deprivation results in poor memorizing, schematic thinking, which yields wrong decisions, and emotional disturbances such as deteriorated interpersonal responses and increased aggressiveness” (Orzeł-Gryglewska 95). Sleep deprivation hinders the abilities of the mind, harms the body, and shortens length of life.
The TED Talk video that I watched was Why do we sleep by Russel Foster. This TED talk was about why we need sleep and how getting less than the suggested amount affects the brain. There are three main reasons why we need sleep; restoration, energy conservation, and brain function. Only certain genes are turned on when you sleep so you need to sleep in order for those genes to turn on and allow you other genes to be restored, while sleeping you save about 110 calories, sleep helps enhance creativity, and your brain is less likely to retain information if you’re sleep deprived and trying to cram information. On average a teen needs 9 hours of sleep, in the 1950s the average teen was getting 8 hours of sleep, today on average teens are getting 5 hours of sleep, which is half the amount that we need. If you’re not receiving the amount of sleep that you need your body will uncountable got into micro-sleeping which will happen to at least 31% of drivers in their lifetime.
The average human spends about 25 years of their life sleeping. That is equal to one-third of a person’s life. So if sleep is vital and common among every single human, what do you know about it? What happens when we sleep (Attention Grabber)? Before the 1950s, scientists believed that the brain would just “shut off” when we would go to sleep. It wasn’t until the discovery of the Rapid Eye Movement (REM) state that scientists really looked into what happens in the brain while we are asleep. Studies have found that we go through a cycle of stages during sleep, and it is important for our health (Orientation to Topic). Today, I am going to inform you about what really happens when we sleep, and some issues that are found among it (Specific Purpose). In order to really understand this worldwide commonality, you need to know some background on sleep, the stages in the cycle, and some common disorders (Central Idea). I have taken a year long psychology course that went into depth on sleep psychology, and I have done extensive research on the topic to better grasp it (Statement of Credibility). I want to inform you on sleep so you can understand what happens when you close your eyes every night, and so you can detect any irregularities in your sleep pattern (Statement of Goodwill). First, I will give a background of why and how we know to sleep, then I will explain the stages in the sleep cycle, and finally I will tell you about some common disorders (Preview).
In the prospect of this article, sleep disorder can play a major role in your life. When there becomes a lack of sleep, there are many things that could occur to your body. There could be a risk of cardiovascular disease, diabetes, infections, or Alzheimer’s disease. For example a man by the name of Michael Arnott had trouble sleeping in his fifty’s, but he didn't know the reason behind this. His wife, Mary White stated, “All of a sudden there'd be a change in the speed and I'd look over, and his eyes would be starting to close,” she remembers (White). Now, Arnold was in denial when it came to his problems of sleeping because he thought that he was in good condition. After getting an analysis from the doctor saying that he has moderate obstructive
Sleep is one of the unavoidable daily-living activities and it is one of the most important factors contributing to a person’s health. A quality sleep is essential for the physical, cognitive and psychological well-being of a person. Learning, memory processing and maintenance of the brain are among the most important functions of sleep. In addition to maintaining the brain, sleep has important roles in controlling the
Sleep is undoubtedly one of the most essential requirements for the human body to function properly. It plays a very important role in ensuring the wellness of the human body both physically as well as mentally. In fact, the importance of sleep is clear from the fact that it helps you in maintaining a good lifestyle throughout our entire lifetime. Not only does it help maintain our physical and mental health; rather it also helps in maintaining a decent and healthy lifestyle along with ensuring safety from a number of fatal diseases. It is usually said that the mood in which you wake up is largely dependent on the type of sleep you have been in. This in itself is a big proof of the importance of sleep in our lives. While sleeping, our body finally gets its share of rest and it also gets ample time in rejuvenating from all the wear and tear that it went through during the entire day. Not only this, the body is in its own working condition when we are sleeping as this is the time when it supports the healthy functioning of the brain as well as physical attributes of our body.
Dreams are generally linked with rapid eye movement sleep, or REM sleep, which is a phase that happens near the end of a sleep cycle. REM sleep is characterized by the random movement of the eyes and heightened body and brain activity. One study proposed that there is a definitive link between dreams and emotions, where the reduction of REM sleep causes a reduction in the ability to comprehend the multifaceted emotions in everyday life (Gujar, 2011, p.117). This phase of the sleep cycle has the highest inclination of vivid dreams and studies of MRIs of the brain during REM sleep show that the amygdala and hippocampus play a key role (Gennaro, 2011, p.1458). The amygdale processes the memory of emotional reactions and the hippocampus stores information from short-term to long-term memory. These findings reveal the core mechanism and perhaps the reason that humans dream. Dreams seem to aid in processing emotions by linking them to a variety of memories. The experiences within dreams may not be real, but the emotions that accompany the images and events during REM sleep are unquestionably genuine. Without processing these emotions, the emotions build up and personal anxiety increases. With less REM sleep, people tend to be more agitated and mental disorders are more easily developed
