Sleep Investigation

Sleep is important for our health and well-being. Extensive research has been done on the effects of sleep. These studies consistently show that sleep plays a vital role in promoting physical health, longevity, and emotional well-being. This explains why, after a good night's sleep, we feel better, our thoughts are clearer, and our emotions are less fragile. Without adequate sleep our judgment, mood, and ability to learn and retain information are weakened.

“The Seems The Glitch in Sleep” by John Hulme and Michael Wexler. I think the main message is if you don’t solve the problem quick enough, the problem will get bigger. I think this because the the glitch is getting worse, if Becker doesn’t do something, the glitch will get worse. In the story, Becker had a very bad nightmare. It was made by three giant bed bugs torturing him. The glitch was moving very fast. After that there was the ripple effect, it is when the world have strange and very bad things happen. Then Becker got tortured by the bed again but this time his assistant Simly, helped. Then the bed bugs, Becker, and Simly fell down to the floor below.

Purpose: To inform the audience about what sleep is and how it helps the body.

Thesis: Sleep plays an essential part in a person’s health and well-being; the way we feel while awake is dependent upon what happens to your body while asleep.

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).

Research in the sleep lab has determined that the majority of our dreams are in color. Bob Van de Castle, a psychologist that studied dreams reported that when dreamers were awakened during a dream, distinct color was reported in 70% of the cases and vague color in another 13%. So why don’t we recall color in our dreams? Recalling color is likely subject to the same mechanisms as recalling any image in a dream, or remembering the dream at all. The sleep stage prior to waking might have something to do with color recall. Research says that people awakened from REM sleep report more colorful and story-like dreams, whereas people from non-REM state of sleep report more thought-like with little storyline or color. The nature or degree of our

In the first half, he uses details such as, “Our bodies need darkness to produce the hormone melatonin, which keeps certain cancers from developing, and our bodies need darkness for sleep.” Proving the point that in order to avoid those diseases, our bodies need that darkness. In addition, he also uses the fact,” Sleep disorders have linked to diabetes, obesity, cardiovascular disease and depression…recent research suggest

I’m reading Horrible Science: Frightening Light it talks about the light that is blindingly obvious. It’s just sunshine and the light-bulb in your living room. The science of light is full of sizzling, squishy, horrid facts that teachers like to keep you in the dark. This book told me how lethal laser beams can sizzle human flesh, why dead bodies make ghostly glowing lights, how rattlesnakes can find you in the dark, why contact lenses were moulded from dead people’s eyeballs, how eclipses turn night into day, how stars have colours we can’t see, how to use light to zap enemy missiles. Through this story I learned many helpful lessons about the light.

Dreams have a lengthy record of being a subject for debate and a source of motivation. In ancient Egypt, pharaohs had several interpreters to decipher their dreams as they believed they were messages from the gods (Lincoln, 1935, p.68). The ancient Hebrews believed that their dreams were tied to divine revelations as well. Native American tribes believed that dreams were a connection to their ancestors and used obtaining a vision from a dream as a rite of passage (Tedlock, 1981, p.324). In the present day, every night all across the world, people still experience sequences of imagery encompassed by sensations and emotions while asleep. The average person tends to dream up to seven times a night

In the Lack of sleep may shrink your brain by Dr. Calire E.Sexton the hypothesis of the experiment or study is: to examine the relationship between sleep quality, cortical, hippocampal volume, and atrophy within the participants, explore the effect by comparing correlations between the different ages, body mass index, and blood pressure. The study involved 147 participants (92 females, 55 males) and each has different characteristics being measured during this experiment. The dependent variable was sleep quality of the adults being measured using the Pittsburgh Sleep Quality Index and correlated with volume and longitudinal measures of atrophy. The independent variables being the different age groups and included physical activity, body mass

In 1830, Robert Macnish published, “the Philosophy of Sleep” where he says that sleep is, “the intermediate state between wakefulness and death; wakefulness being regarded as the active state of all the animal intellectual functions, and death as that of their total suspension... Sleep is a temporary metaphysical death.” From a Chinese medical perspective this relates to the inter-transformation of yin and yang; If we do not reach a maximum of yin, we cannot yield a full quality of yang. Sleep, or a regular ‘metaphysical death,’ is as essential as food and air. Many say that sleep is the best medicine and lack of sleep, well, that may be seen as medicine too. From some Taoist perspectives, less sleep means longevity. From many European perspectives,

The behavior change I decided to focus on is: getting more sleep every day. For this, the article I chose is: Why Is Sleep Important. Sleeping plays a key role in maintaining a healthy life as it affects our mental activities, as well as physical health. When we sleep, the same as when we are awake, we tend to process information outside our conscious awareness. Whenever we are asleep, we may think our brains turns off but it is always still active because of the biological rhythm that is has. Having enough sleep helps us humans, and living things in general, ameliorate our immune system and gives our neurons time to repair themselves. Another benefit of sleeping enough is the fact that it helps rebuild the memories that may have faded, it reactivates them. Sleeping boosts your creativity. In fact, people who sleep on a task after having worked on it, tend to solve difficult problems more effectively. It also supports growth by releasing a hormone that is necessary for muscle development.

Sleeping is extremely important for all mammals, but humans especially. Without sleep we are unable to function properly and at 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.

Why is sleep so important to us? There have been studies done that suggest that sleep deprivation can be detrimental to or decrease the function of our immune systems. Just think, how often was it that after many days of continual sleep deprivation did you start to think that you had a cold? Sleep deprivation can also result in a decrease in core body temperature, decrease in the release of growth hormone, and possible cause an increase in heart rate variability. Sleep also seems to be important in order for our nervous system to work properly. Without sufficient amount of sleep, our behavior and our ability to do things are impaired. We feel drowsy and are unable to concentrate after not getting enough sleep. With enough sleep deprivation, it has been found that some begin to hallucinate and develop mood swings. Higher-ordered cognitive task become more difficult to do where it has been shown that tests that require speed and accuracy have lower results compared to those that are not sleep deprived. Judgment is also impaired; it has been tested that riskier behavior is more likely to occur when sleep deprived. (2).This is part of the reason why you should not drive when you are sleep deprived. Aside from the risk of falling asleep at the wheel, since judgment is

However, this does not seem to be applicable to humans - in order to meet the current demands of society (such as work and social activity), being awake all of the time would be of extreme value, especially as electric lights and so on mean that 24 hour activity would be possible. It is difficult to see, then, how sleep could be advantageous as Webb suggested. Neither can Meddis' (1975) theory be easily applied to humans. He suggested that sleep evolved so that animals can remain inactive and, consequently, hidden at times when they are more likely to be predated. As humans are the species highest in the food chain, it is unlikely that this best
