Evolutionary theories often emphasize that humans have adapted to their physical environment. One such theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and waking—even if they are not exposed to the usual pattern of sunlight. To test this notion, eight paid volunteers were placed (individually)b in a room in which there was no light from the outside and no clocks or other indications of time. They could turn the lights no and off as they wished. After a month in the room, each individual tended to develop a steady cycle. Their cycle at the end of the study was as follows: 25, 27, 25, 23, 24, 25, 26, and 25.…
The main idea that is acclaimed by Dave Stuart Jr. in the article, “Teachers, Student, and Sleep,” is that sleep affects performance and that there are many factors that affect sleep. He puts forth statements talking about how sleep can affect performance, health, and mood. He also states many reasons sleep quality and quantity can be skewed; those include the blue light from electronics, exercised, eating habits, and the amount of natural daylight you are exposed to. Concluding the article’s ideas, sleep has enormous importance but is extremely fragile.…
The results show that the average sleep cycle is not 24 hours. This allowed us to reject the null hypothesis. We used the data to determine if the average person’s sleep cycle was 24 hours. After examining the information we see that is not the case.…
Julia’s lifestyle is based on work, she spends 9 hours at work and her husband spends between 11 and 12 hours at his work. Even though her husband is getting well paid for his job the amount of hours in which he has to stay at work is ridiculous.…
Likewise, Crook is isolated by his skin color because he is black while the other people on the ranch are white. He has to live by himself in the barn and is not allowed in the bunkhouse with the rest of the other people. He is also not allowed to play cards with the others because of his skin color and also because they think he stinks. He has to go into his room when it gets dark and all he can do is read he can’t do anything else because he doesn't have anyone that lives with him. While everyone else can go into the bunkhouse and talk or play cards. He gets mad when people come into his room because he is not allowed in the bunkhouse so he thinks it is fair if they are not in his room and he also wants his own privacy. In Mice and men…

Shift work described a type of job in which individuals have to be alert at night when they work, and they sleep during the day. This results in reduced quality of sleep because it goes against our natural biological rhythms as daytime sleep can be interrupted due to exogenous zeitgebers such as light and outside noise. (AO1)…
The research investigation aims to find out the sleeping patterns or sleep wake cycle (the species-specific biological pattern of alternating sleep and wakefulness, in humans) of students between the ages of 13-19. Specifically this task aims to investigate the number of hours the students sleep on weekdays compared to weekends and if the participants wake up on the preferred time on school days. It was hypothesised that teenagers (13-19 years old) are achieving less than the recommended hours of sleep (8 -9 hours) on weekends. In addition the time that they wake up on a school morning is not there preferred time. The hypothesis was supported by previous research such as research done by DR Karl S. Kruszelnicki 3 May 2007. In this research DR Kruszelnicki states that the natural circadian rhythm (A circadian rhythm is any biological process which displays oscillation of about 24 hours, they are adjusted to the local environment by external cues called zeitgebers, commonly the most important of which is daylight.)…

According to the National Sleep Foundation, sixty percent of Americans have sleep deprivation, an outcome of today’s advanced technology. Improvements of the technology and realization of the imaginations offer people more choices to expend their limited amount of time: for example, cell phones, which are among the greatest inventions in the twenty-first century, let people listen to music, take pictures, and even watch TV shows. Because of those innumerable entertainment options, they leave their own health as the last concern, meaning that sleep is in their least priority, without knowing how much a lack of sleep influences their life. The play Macbeth, a tragedy about the rise and fall of the protagonist, Macbeth, reveals the significance…
The activities performed for leisure are divided into two categories; passive leisure time and active leisure time. The department of Human Resources and Skills Development Canada (2013) defines passive leisure time as the time spent on rudimentary activities that require minimal mental and physical exertion. In contrast, active leisure time is the time spent on leisurely activities that require the use of physical or mental abilities such as playing sports or socializing. For the purpose of clarity, the term active leisure time will be referred to as recreation time in this paper as both terms encompasses similar meanings. From Sunday, January 6th to Saturday, January 12th, a large portion of my time was spent sleeping, attending classes or studying. On average, roughly eighteen hours per day were spent performing these activities this particular week. Leisure time occupied roughly twenty-two hours of the week with an average of three hours per day. This time map indicates that I am fortunate enough to have ample time for relaxation and leisure every day of the week. Similarly, time for recreational and physical activities occupied seventeen hours of the week with an average of two and a half hours per day. The Public Health Agency of Canada (2012) suggests that adults aged from eighteen to sixty-four years old should be performing moderate to intense activities at least two and a half hours per week to achieve health benefits. According to the time map, two and a half hours were spent every single day being moderately to rigorously active, indicating that I have a fairly active lifestyle.…
David Hilbert was born around 1682 in Konigsberg in East Prussia, which comprised a section of Germany and modern day Kaliningrad Russia. His father was a judge and his mother an amateur mathematician. He became known because of the contribution he made in mathematics and physics in the twentieth century. Hilbert is well remembered for landmark researches he conducted in algebra. He also left an indelible mark in axiomatic geometry and mathematics. Hilbert also profoundly contributed in other areas such as invariant theory and mathematical physics. Hilbert studied at the university of Konigsberg, and during his studies, he made several trips to abroad. He visited Europe on study Tours where he managed interact with some of the leading scientist during that era.…

Sleep is one of the most fundamental components of a healthy existence. The phenomenon of sleep deprivation, resulting either from lifestyle choices or the undertreatment of sleep related illnesses, could be a factor for a multitude of health disorders prevalent in today’s society (Nature, 2005). It is suggested that people of industrialized countries obtain about 20% less sleep today than they did a century ago. Sleep deprivation has been linked to Type 2 diabetes, obesity, and has also been found to significantly increase the chance of a motor-vehicle accident (Wilson, 2005). In order to address the problem of sleep deprivation, it is imperative that the motivation behind sleep and sleep deprivation is understood. This essay will look at sleep and sleep deprivation through five different perspectives of motivation: evolutionary, psychodynamic, behaviourist, cognitive, and hierarchy of needs. This essay will then argue that by viewing sleep and sleep deprivation from a multitude of perspectives, a holistic understanding of the phenomena might be achieve.…
Sleep is considered a vital part of human life. Without sleep, the human body is unable to function properly. By recording my sleep patterns over a 72 hour time period, I was able to notice patterns in my circadian rhythm, my sleep cycle, and the effects of sleep on my body. Although I did not have any interesting dreams to analyze in my sleep journal, I did collect some interesting data.…
