Sleep
Sleep has plagued the existence of complex organisms since their evolution early on in the formation of Earth. Although there are various stages to the sleep cycle, essentially one falls into a temporary coma for a few hours each day. It seems totally irrational that evolution would dictate a system where one lets down their guard for hours every day, leaving one prone to a deadly attack. It seems a fairly logical assumption that sleep is exceedingly important to life if, in order to get some rest, animals in the wild irrationally risk their lives. Our bodies are telling us that they have run at full capacity for long enough, and therefore need to replenish valuable resources.
In researching sleep, I found "replenish" to be a key word. During the day, one's body is constantly metabolizing ingested food and water, turning them into useful forms of energy. The body depletes a great deal of its energy stores (glycogen, mostly) and also experiences a large buildup of toxic byproducts (lactic acid, for example) during the day.1 Therefore, it is absolutely necessary to replenish these lost stores and get rid of the toxic chemicals coursing through your blood. Four hours seems to be the minimum amount of time one can sleep per night in order to coherently function during the day. A lack of sleep can have grave consequences, greatly caused by the inability of your immune system to work without rest.
Sleep is a multistage cyclic process, involving five steps. Fast waves, called "Beta" waves are those which result from being awake. Once you become sleepy and close your eyes, your body relaxes and your brain waves greatly slow down, becoming "alpha" waves. After approximately five minutes in this relaxed state, your brain waves further slow down to become "theta" waves, transporting you into Stage I sleep. Stage one sleep generally does not last very long, and is accompanied by a lowered pulse rate and slower breathing. After a few minutes in Stage I sleep, Stage II sleep begins, marked by a further slowing of brain waves as well as bursts of electrical activity, called "spindles." These bursts manifest themselves as a sort of twitching.
Asking just about any animal rights activists on the thoughts of animal testing, it is virtually unquestionable that the majority of them would come across the thought of some of the laws in regards to animals and how animals are “protected” by these laws. Trained scientists and researchers take on the key role of testing on animals in laboratories and facilities throughout the world. Simply in the United States alone, there are very few laws protecting animals from the unnecessary amounts of suffering the researchers force upon them with many broad exceptions. Additionally, in reference to the scientists who perform these tests, the author lists and goes into detail explaining certain associations that infrequently examine and inspect animal testing facilities to ensure that the guidelines and standards are being followed. The author then goes on to state the problems among these organizations that were originally created by the government to assess
So for an average sleep time of eight to ten hours, we go through this sleep cycle four to five times a night. In stage one of the sleep phases, we are in a light sleep that lasts anywhere from five to ten minutes. In this stage, our eyes are still moving slowly and our muscles are slowing down, but may still have sudden muscle contractions like as if we were being startled or as if we were falling down. People in this phase may not feel rested if they are awakened, and might not of felt like they were even asleep at all. In stage two of the sleep cycle, you have successfully fallen into a light sleep. During this cycle your heart rate has slowed down, and your body temperature has dropped. You no longer have eye movement, and your body is finally resting the parts it has used through out the day. The next stage, which is stage three is also combined with stage four of the sleep cycle. These two cycles together are known as the delta sleep or the deep sleep stage, and is a very important part of the sleep cycle. During these cycles your body repairs and re-grows tissue, strengthens the immune system and builds bone and muscle. In these cycle it may be very hard to wake a person up, and if woken they may feel droggy or “out of it” for several minutes. In these stages is when most people have night terrors, experience sleep walking, or sleep talking occurs. In an adults average time of sleep this takes up about fifteen to twenty five percent of the time of sleep. Lastly, there is the REM cycle, which is also known as paradoxical sleep. During this cycle is when most of your muscles are paralyzed, your eyes are moving rapidly, and your breathing, heart rate and body temperature are not regulated. Vital signs show that during this stage, the arousal and oxygen levels

There are four stages to sleep. Stage one, two, three, and four also known as REM. During stage one you will commonly see twitching, your brain is setting
There are five stages of sleep. The first stage is when one prepares to drift off. During this stage, one experiences Alpha and Theta waves. This stage generally lasts five to ten minutes. The second stage lasts about twenty minutes. The brain begins to produce short periods of rhythmic brain waves known as Sleep Spindles. Body temperature begins to drop and the heart rates slows down. During stage three, slow waves

Much of society mistakenly believes that each individual needs eight hours of sleep in order to have a full night’s rest. This is untrue because the amount of sleep you need has a large dependence on the many factors that influence healthy energy. Age is a large indicator of how much sleep is relevant to an individual. Studies done by Milner (2008), “Benefits of napping and an extended duration of recovery sleep on alertness and immune cells after acute sleep restriction” show that an adult needs nine hours a day in order to carry out work productively, feel rejuvenated, and maintain contented moods. In contrast, infants tend to need more time to rest their bodies even though they are less active. A young baby spends 2/3rds of their day
A major ethical concern that has been under speculation for many of years is focused around animal ethics, and whether or not certain animal practices are just or inhuman. There are many questions that focus around fundamental issues concerning the moral status of animals. It is critical to understand the difference between a concern for animal welfare and a concern for animal rights. A current issue that is important to understand and analyze is animal experimentation, and although many consider it to be an unethical practice, there are many pros and cons to the controversial topic. Although animal experimentation has been very beneficial medically, the argument can be made that using animals to experiment is not always necessary.
Sleep is a behavioral state characterized by little physical activity and almost no awareness of the outside world. Sleep is actually made up of two separate and distinctly different states called REM sleep (rapid eye movement) and NREM sleep (non-rapid eye movement). With NREM sleep it is further divided into stage 1-4 based on the size and the speed of the brain waves. Step one is the stage when you drift off to sleep or doze off. For example people doze off in class because you are bored and have nothing to do but listen to the teacher talk. Some parents may call it a cat nape when their kids go to sleep for about ten minutes or so. The second stage is called an intermediate stage of sleep. That is when
Conservative people would call Banksy’s graffiti as being vandalism instead of recognizing the fact he brings social issues to the eyes of the people through artwork. “Son of a Syrian Migrant Worker” and “Migrant Birds” both display how ridiculous we, humans, truly appear when trying to argue over immigration worldwide. Graffiti benefits urban societies of the 2010 era because, the art form is not only used to express ones’ emotions but, express their political objectification, in this case, Banksy addressed the issue of immigration. Banksy’s graffiti functions as a social critique because he uses humor to explain the societal issue of immigration; “Migrant Birds” is more persuasive than “Son of Syrians Migrant worker” because Banksy shows
Because sleep is vital to our well-being, we have to make sure to get an enough quality sleep at the right times as it helps to protect our mental and physical health, quality of life and safety.
The four stages of sleep are REM (rapid eye movement sleep), NREM1 (non-rem), NREM2, and NREM3. During the REM stage “your heart rate rises, your breathing becomes rapid and irregular, and every half-minute or so your eyes dart around in momentary burst of activity behind closed lids” (Myers, 2014, p. 96).
Getting enough sleep can increase our chances of being more mentally/physically healthy and our safety throughout the day. How we feel throughout the day is depending on our sleep. Lack of sleep can lead to impaired judgment and actions, which can be a safety hazard towards yourself and your surroundings. When we sleep, our bodies are working to revitalize the brain to form new pathways to help with memory functions and our physical health such as healing repair heart and blood vessels and hormone balance. It is very important for everyone to maintain a good night’s rest to maintain daytime performance and lower stress. Sleep will reduce the levels of stress, help others gain control on their actions and avoid depression. Contributing to these sleep benefits will change your body and mind
Sleep is very important for human beings. Sleeping means taking rest for every person and each person spends one-third of his lifetime sleeping. Without sleeping, no one can exist in this world. Sleeping is essential for a person’s health and well-being throughout his life. Getting enough quality sleep at the right times helps all people protect their mental health, physical health and safety. A person who does not get enough sleep might suffer from mental disorders, diseases and even harmful situations. Therefore, it is important for every human being to have enough sleep.
