Observation Theories: The Way We Sleep

Sleep is a complex mysterious phenomenon that we don’t know much about including why we dream and different actions associated with lack of sleep like yawning or illness, but there are many theories as to why these things occur along with facts. Why do we dream or have nightmares? What is the point to these things and how do they contribute to our health? Scientists are doing their best to research these things but sleep and things related to it are very mysterious and many things are still left unsolved. There are also many disorders and illnesses connected to the need for sleep and sleep itself, including sleepwalking, sleep apnea, snoring, yawning, dreaming, nightmares, and other various things.

Sleep is a state of altered consciousness, characterized by certain patterns of the brains activity and inactivity. An altered state of consciousness is when a person is not completely aware of their surroundings. Some researchers believe that we sleep to clear our minds of useless information. Other people believe that it is a type of primitive hibernation: we sleep to conserve energy.

The question “why do we sleep?” is a very difficult question to answer. One way to think about why sleep is important is looking at sleep as if it was food. Food helps us feel better and also helps the human body function properly.There are many different assumptions on why we sleep.The first is that sleeping allows the body to repair cells damaged by metabolic

The two general approaches taken by theories of sleep is both restoration and evolutionary theories. Restoration theories suggest that sleep exists in order to repair and restore the body. While the evolutionary theories that relate sleep ability to survive in a hostile environment.

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).

First, why do we sleep? Sleep is a very complex and sometimes a very hard to understand matter of human life. We all know that sleep is a necessity and if we don’t get an adequate amount then things start to deteriorate in our mind and body. Thomas Edison

Out of the four main sleep theories, I believe cognitive development best relates to the events of today, and the medical procedure Joel received. I believe cognitive development relates well to the events of today because as said by G. William Domhoff (2014) “dreams dramatize our wishes, fears, concerns, and interest in striking scenarios that we experience as real events.” If you take a look at the categories of dream content Domhoff states, you realize most of your dreams you have had before fall into one or more of those categories. If you were to think back you could probably recall waking up after having a nightmare upset and with a racing heart. This is because dreams are so dramatically real like Domhoof states, and this explains why

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,

My proposal for a research study would be to observe and understand what effects, if any, sleep or a lack thereof have on general day-to-day interpersonal social communication and other interactions between people. A large sample would be surveyed and shadowed for a short time by the five researchers in charge of the project in an effort to dichotomise the group into those who are generally negative, hostile, or unfriendly, and a group of those who are generally positive, amicable, or friendly. How each group is assessed generally and dichotomized, their general social “flavour,” is the dependent variable. How each of the five evaluates each person in the large sample would be compared, and only the twelve with the most consistent evaluations

In summary, evolution theory proposed that sleep is adaptive and animals which are in the higher level of the food chain or with higher metabolic rate need more sleep. When it comes to the cause of sleep, everyone has an internal body clock which calls circadian rhythms to control when you are awake and when your body is ready for sleep. The circadian rhythm is typically 24-hour repeating and there are two processes interact to control it. The first is a pressure of sleep, which controlled by adenosine, that builds with every hour when you are awake.

First, let’s review some reasons why people need sleep. People need sleep for multiple reasons. The general reason is that sleep helps our physical and mental help. It does this by resorting our body tissues, encouraging body growth, and increasing our immune system. It also helps to keep our mind sharp, enhance our moods, and helping learning and memory (Pastorino & Doyle-Portillo, 2013, p. 4-1a). There are five stages or sleep, the four stages of Non-rem sleep and the single stage of Rem Sleep. Stage I of

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.

 A most popular theory on why we sleep is the restorative theory of sleep:

A typical night’s sleep is much more complicated than just closing your eyes and waking in the morning. As humans, we live our life on a circadian rhythm. This means that changes occur roughly based upon a 24-hour basis. This circadian rhythm plays a major role in when we get tired and decide it’s time to sleep. This rhythm is theorized to have helped us stay safe thousands of years ago. We would fall asleep during the time that their seemed to be threats roaming around in the dark. to Once we finally get to sleep, our brains and bodies are doing much more than laying in complete stillness. There are five distinct stages of sleep that we experience as we sleep. Each is uniquely different and serves a purpose throughout the night. The first stage of sleep is a very light sleep that lasts for 5 to 10 minutes. During this stage of sleep, you may not even realize that you’re sleeping. While in this stage of sleep our brains power down by 50 percent and produce theta waves four to seven times per second. We proceed to stage two after this. During stage two, our brains power down

Sleep is a complex form of resting state that is observed in animals that have highly developed nervous systems. Birds and mammals, including humans, do not simply become inactive and slow to react during their daily rest periods. Their nervous systems shift into modes that differ from but are not necessarily less active than wakefulness.
