Sleep: Why We Need It or Do We? There are many different philosophies on how much sleep the body needs or doesn’t need. Sleep has been said to be the body’s way of refueling. It allows the body to restore its mental energy (msnbc.com). The question is how much sleep does the body truly need to function? One theory pertaining to sleep is that if your body has a lack of sleep it would just adapt to less sleep. Sleep deprivation can cause us to lose our agility, cognitive, and immune responses. There is no explanation as to why people sleep an average of eight hours each night (msnbc.com). Scientists are still exploring the bodies need for sleep, depths of sleep, typical sleep patterns, the negative impact a lack of sleep can cause, if age and schedules of people affect it, and to what degree does it affect the functions of the nervous system. Sleep deprivation has been a major factor in some of the biggest disasters in history. The notable ones are the Exxon Valdez oil spill, the 1986 Chernobyl nuclear meltdown, and the 1979 Nuclear accident at Three Mile Island (Peri). Drowsiness is also a leading cause of accidents according to National Highway Traffic Safety Administration. They estimate that nearly 100,000 automobile accidents and 1,550 crash-related deaths occur each year in the United States (Peri). Some work related injuries are also cause by a poor quality of sleep. There are many other negative factors that are related to sleep deprivation. It is estimated that 90% of people who suffer from insomnia also suffer from other medical issues. People who Gautier 2 suffer from sleep disorders are at a higher risk for high blood pressure, stroke, diabetes, irregular heartbeat, heart failure, heart attack and h... ...stems. The researchers have found a connection between lack of sleep and obesity in adults and children. Reduced levels of leptin, a hormone that is produced by an adipose tissue hormone, cause the body to not suppress the appetite (Colten). In conclusion, scientists have discovered that the body is negatively impacted from a lack of sleep. Human bodies need sleep to restore and maintain its cognitive process, bodily functions, overall health and well being. The body has to have all depths of sleep in order to function properly. Sleep deprivation can cause serious health issues such as heart disease, lower sex drive, obesity, and heart attack. Age is a factor in how many quality hours we require throughout our lifetime. Scientists continue to discover more information every day on how our sleep can impact the body, mental state, and overall happiness.

The Positive and Negative Impacts of Technology on Family Life

The Positive and Negative Impacts of Technology on Family Life â€Å"Is technology tearing apart family life? Text messaging, social networking, and online video are changing the way parents and children see the world—and each other. † There are many technologies in today’s world that are widely used not just as a want, but as a necessity of life. This term paper will focus on relationship between family life and computer technologies, which have become the most widely used technology in the world due to its variety of functions including SNS, mailing, online face-to-face video chatting, and assignment completing tools. Computer technologies have both positive and negative effects on family life. As more and more families are beginning to own their own computers (computer internet users in North America reached to about â€Å"78. 3 %†) , the effects of technologies on family life is becoming more easily identifiable. This term paper will come across both the benefit and negative effects of using technologies on family life. There are the negative effects which include the isolation of family members, and parents bringing their work home. On the other hand, linking relatives together is one positive effect that technologies have on family life, and being instantly updated on other family members’ status is also a huge benefit. Overall, the benefits of using technologies outweigh the negative effects. One negative effect of computers on family life is less face-to-face contact between family members. In most families, each family member has their own computers or smart phones that are kept in their own rooms. Nowadays, the functions of computers and smart phones are not just limited to internet surfing, and assignment tools. They are also widely used for social networking services (SNS), such as; Facebook, Skype, and Twitter just to name a few. As a result of the increasing time consumption of using the functions on computers, family members are now more isolated from each other and cannot talk to each other face to face as often as before when technologies were not as important in day to day living. Even when there is only one computer per family, there is an interruption with family life. If one person is using the computer, then other family members do not want to just wait while the computer is being used, so they will go to a different room and each person will end up using the computers at their own leisure. The use of computer games is another thing that has reduced human contact between family members. Before computers were used in the home, if someone wanted to play a game, they usually had to find at least one other family member to play a board game or card game with them. That forced families to spend more time talking to each other. Now if someone wants to play a game that requires more than one person, they can just go on the computer and either play online against another person, or they can play against the computer. Playing games on the computer makes it easier to be isolated from physical contact with other family members. Now that you don’t have to ask person in your family to play a game, most families don’t spend as much time talking to each other and learning about each other. Another negative cause that computers have on family life is that many people now bring their work home with them instead of leaving it at work the way they used to. People’s work is now invading the privacy of their home. People find that it is easier and more convenient to work at home, so they bring their work home allowing it to invade their home. When people bring home their work, it separates families by causing parents to spend more time at home working, and less time with their family causing parents to not know as much about what is going on in their children’s lives. Bringing work home separates families, making them not as close knit as they would be if they spent more time together talking. Computer technologies have not just had negative effects on families; they have also had some positive ones. The use of Social Networking Service (SNS) through computer is one of the positive effects that technologies have had on families. With the use of computer functions such as; e-mail, Messengers, Twitter, and Skype, families can take care of things that they would otherwise have to leave the home to take care of. Using SNS also allow families to communicate with other family members who might not live close by. For example, I Skype (free online webcam chatting) my father in Korea at least twice a week. Without the use of SNS I wouldn’t be able to communicate with him nearly as much because phone bills would be too expensive for me to afford. So, because of SNS I am able to remain close to my father even though he is in Korea, and I am in Canada. A second positive effect that technologies have had on families is the use of instant texting service. This allows families to talk to each other and have a fairly normal conversation with each other even though they might not be in the vicinity. I personally use instant text messaging services to talk to my parents, my sister, and my relatives regularly because it keeps them updated on what is happening with me on a daily basis. While I am at school, I am still able to stay in touch with everyone back home without having to call each one of them separately. For many people who are away at school, instant texting services allow them to stay in touch with friends and family even though they are not at home. A third positive effect that technologies have had on families is computer web pages (Facebook). Web pages allow families to post pictures of themselves and other family members so that everyone in the family can go to the web page and view the pictures. My sister has a web page that explains things about her, and it has pictures of her and friends. One of my other uncles who lives in Korea also has his own web page. On his web page, he has pictures of his baby daughter. By going to my uncle’s web page, I have been able to see pictures of my baby cousin as she has grown and changed. Many other families have web pages similar to my families that they use to watch their families change even though they are not in the same country. In conclusion, the negative effects of using technologies posed can essentially be overcome by use of SNS technology through computer or phone. When there is lack of human contact between the family members, then Skype can be used to perform online face-to-face chatting. The use of technologies also proved to be more efficient when each family member want to be updated on each others’ status. Without the use of technology, instant messaging system would not be possible, so the relatives or family members would not be able to interact with each other as easily. APA 6th edition reference 1.

Analysis Of Fahrenheit 451 During The Cold War

Andrea Aggarao Mrs.Thunell English II Honors 7 April 2016 Guy Montag’s Transformation Throughout Fahrenheit 451 Ray Bradbury wrote his novel, Fahrenheit 451, during the Cold War. Although he initially wanted to warn people about the danger that technology can greatly affect a society and community for the worst, Bradbury s novel was interpreted as commentary for censorship at the time he was writing the novel. His use of many examples of reality was thought to emphasize this point. Even so, the main character of the novel is an example of a drastic dynamic character. A dynamic character usually undergoes a transformation in relation to events of the plot. Ray Bradbury’s dynamic character in Fahrenheit 451, Guy Montag, undergoes a transformation throughout the novel that is influenced by his interactions with other characters and his feelings of separation from society as he explores himself through reflection in books. Bradbury used the novel to comment on society during the Cold War. The novel was written in the time period after World War II and as the Cold War took place in American history. Many details of the city in Fahrenheit 451, alludes to many historical practices during this time. Hoskinson mentions that Americans were arresting and investigating anyone suspicious of being a communist without concrete evidence in his article of the historical context of the novel. The novel mentions the real world advancements in technological warfare, such as the atomic bomb.Show MoreRelatedCold War in the Eyes of Ray Bradbury1689 Words   |  7 PagesAmerica (Waukegan, Illinois), wrote two very distinctly different novels in the early Cold War era.

Ray Bradbury created this dystopian society of backwards thinking in his novel Fahrenheit 451. When he wrote the book, during the Cold War, the United States was beginning to censor many things and his fear of what it would turn into inspired him to write this novel.
