Dreaming
Each and every night our eyes grow heavy and our minds tire. We find ourselves dragging our feet to bed. Normally we drift off to sleep and enter a stage of dreaming. As we fall asleep, our brain prepares for dreaming. Dreaming makes night interesting. Some dreams go in and out of our mind for long, while we can recall others just a few seconds after. But what is the truth about them? Dreaming is a natural event our minds go through at night.
“On average, humans spend one third of their lives sleeping (Heijnen & Edgar, 2010)”. Sleeping is very important to all humans. We need sleep to function properly and achieve our fullest abilities. When we sleep we grow, and it is an opportunity for us to dream which has many benefits. Sleep is also a way for us to relieve ourselves of stress. “About 90 minutes after falling asleep, the brain creates the fertile conditions for dreams to occur (The brain prepares for dreaming, 1997)”. “When we sleep, we go through five sleep stages (Obringer, 2005)”. These stages are known as the sleeping cycle. The first stage consists of light sleep and relaxation of the muscles. During the second stage, our breathing pattern and heart rate slow down and we experience a decrease in body temperature. Halfway through the cycle we enter a deep sleep. The brain starts to produce slow delta waves. “Delta is the slowest (zero to four cycles per second) and is present in deep sleep (Obringer, 2005)”. In the fourth stage, we are in a very deep sleep with rhythmic breathing and limited muscle activity. Throughout the fifth stage our breathing and heart rate quicken and we enter the Rapid Eye Movement sleep. “Rapid eye movement (REM) was discovered in 1953 by University of Chicago researchers Eugene Aserinsky, a graduate student in physiology, and Nathaniel Kleitman, Ph.D., chair of physiology (Obringer 2005)”. During REM our bodies enter a paralysis condition. “This paralysis is caused by the release of glycine, an amino

    Sleeping is something we spend doing approximately one third of our human life cycle and can vary in quality from one night to another and have a tremendous impact on our daily performance when we awake the next morning by either having a lousy day or having a productive day. “Some 70 million people in the United States have a sleep problem.

    There are four primary stages of sleep in which human beings cycle in and out of (Pinel, 2007). The first stage is referred to as emergent sleep. During this phase EEG waves are both low voltage and high frequency. The second, third, and fourth stages are made of higher levels of EEG voltage and a decrease in frequency. The second stage of sleep mainly process two additional characteristics which are sleep spindles and K complexes (Pinel, 2007). Delta wave patterns can happen during the third stage of sleep. As the fourth stage of sleep occurs the delta waves become the most dominant pattern within an EEG (Pinel, 2007).…

    The nervous system is an extremely elaborate biological machine. Without question, the nervous system is a system so intricate and comprehensive that professionals in the field of medicine to this day do not have a “complete picture” of each of the working details of the human nervous system. Of these different mechanisms, perhaps the one most riddled with speculation, is the mechanism of sleep. In discussing regulatory process, sleep is perhaps one of the most essential to the healthy upkeep of the human nervous system. This process is such a necessary behavior that without it, the nervous system, and the overall health of the individual in question can become compromised (to the point of fatality) without it.…

    Sleep is one of the body's mysterious functions that is required by all human beings. The function of sleep is still not fully understood, although a battery of experiments and a multitude of theories attempt to explain it. One of categories that falls under the study of sleep is sleep deprivation. Sleep deprivation is an important study since it affects individuals, groups, and the environment. Unfortunately, sleep deprivation affects a large amount of the human population, afflicting millions in America alone. Studies has shown that the loss of sleep time correlates to lowered cognitive performance and impaired mental activity, coupled with physical problems that turn into problematic medical illnesses.…

    David Myers, the author of Exploring Psychology the eighth edition, says, “Everyone needs to get eight hours of sleep” (Myers, 75). This quote I think is so underrated, because some people in our world today only get six to nine hours of sleep, on a daily basis. If you think about it, going to sleep is not that easy. There are five unique stages to sleeping. In stage one, this cycle is considered to be between being awake and slightly dozing off. When you are in this cycle, you wake up, but you do not feel like you fell asleep. The brain produces theta waves, which makes the brain waves decrease when you go into other sleep stages. In stage two, the brain begins to relax more. The sleep spindles, which are rapid, rhythmic brain waves, are present in this cycle. Your body temperature starts to decrease and your heart rate starts to slow down. In stage three, this cycle is forwarded to deep sleep. In stage four, you are in a deep sleep, but not enough to dream. Also in this cycle, “some children might wet the bed or even sleep walk” according to David Myers. In stage five, also known as the rapid eye movement (REM), the heart rate increases and eyes begin to move under the eyelids. Most dreams occur here because the brain activity was increased.…

    Sleep is a vital part of life; it helps with body development, repair, and psychological functions, such as memory processing. However, when we have important tasks to accomplish, it seems that sleep wastes valuable time. At some point, we have all pulled an all-nighter and wished that we did not need to sleep. In Lois Tilton’s “‘Sleep, My Little Ones’”, a procedure was developed that “turned off” the natural need for sleep so that humans could function 24/7. Though I sometimes wish I did not have to sleep, I do not think that such a procedure would be practical or beneficial if ever developed because of the strains it will put on humans both physically and psychologically.…

    When we sleep, we go through five sleep stages. The first stage is a very light sleep from which it is easy to wake up. The second stage moves into a slightly deeper sleep, and stages three and four represent our deepest sleep. Our brain activity throughout these stages is gradually slowing down so that by deep sleep. About 90 minutes after we go to sleep and after the fourth sleep stage, we begin REM sleep. REM sleep is primarily characterized by movements of the eyes and is the fifth stage of sleep. During REM sleep, several physiological changes also take place. The heart rate and breathing quickens, the blood…
