Sleep Cycles: The Five Stages Of Sleep

The skirmish between traditional aristocracies and new democracies in Sicily was damaging to the Sicilian people, particularly people who were from conservative family backgrounds. The Leopard by Giuseppe Tomasi di Lampedusa portrays the battle of old vs. new through following the life of an old Sicilian aristocrat, Don Fabrizio, commonly known as The Prince. Giuseppe uses The Prince to highlight the outmoded side of Sicily and the struggle to deal with the Risorgimento (Italian unification). Although many people during this time were accepting change, The Prince tried to ignore the change which is portrayed through the motif of sleep.

The first example the author uses is a young adult name Randy Gardner. For a science project, he has deprived himself of sleep for 11 days in a row. A scientist named William Dement kept track of Randy’s brain function during the course of the experiment. Early on in the experiment, his symptoms included: forgetfulness, nausea and irritability. After sleep deprivation for five days he was experiencing paranoia, symptoms of Alzheimer’s and severe disorientation. During the last few days he was experiencing trembling fingers, slurred speech and a loss of motor function.

Sleep can be initiated at any point of the day, as their circadian clock is still in development;

The average person sleeps around 7-8 hours a night, although, 100 years ago people slept 11-12 hours a night because there wasn’t as much to do in a day.

This investigation examines is it possible for light pulses to alter the motor skills, and cardiac movements of biological life forms. Is it possible to change how biological lifeforms functions if we were to shine a light on them every hour at night? Knowing how most animals work, and from that of human experience I can say that light is what makes us stay awake; therefore if we have a light shined on us every hour would we lose sleep? These are the type of questions I will be answering throughout my extended essay. I will talk about how our sleep is affected by light, and monitor this so I can then record the data. I will also be discussing why we sleep. Which you may be wondering how this ties into light, however light does damage our skin

According to (Carpenter & Huffman, 2012, p. 121), there are four stages of sleep; the first four are called non-REM state then the last and final state is called REM )Rapid Eye Movement). When the sleep cycle starts it lasts an average of 1-2 hours; the first sleep cycle has relatively short REM sleep followed by a long period of deep sleep. Later in the sleep cycle REM period lengthen and deep sleep time decreases. Even though cats tend to sleep longer than human its shows that they have slept similar patterns as humans, including sleep phases of REM stage. When human enter REM stage, breathing becomes more rapid, irregular and shallow; the eyes start to move rapidly back and forth. In this stage, the limb muscles become temporarily paralyzed.

There are five basic stages in cycles I go thought when I am going sleep though out the night. Stage one, which lasts about five minutes, my brain waives becomes slower and irregular. Then I would go in to stage two, which lasts around ten to twenty minutes, I would have a regular EEG and less then 50 percent of this time is spent in this stage. Stage three is a short transition, which is made up of twenty to fifty percent delta waves. Stage four is around fifteen to twenty minutes, in this stage I have less than fifty percent delta waves and it is where I get the deepest sleep. Then I would cycle back through stages three and two before I enter into stage five. In stage five, which is called REM, which last ten to twenty minutes and I will

Entering the second hour of sleep, brain wave activity increases and the individual enters into the first REM sleep (rapid-eye-movement sleep) period. The cycle of NREM and REM sleep is repeated throughout the night, with each REM cycle becoming longer and each NREM less deep.

The neonatal or special care nursery environment is one of variable but constant movement, light and noise. Such an environment is not conducive to the entrainment of good sleep habits. Discuss the impact this environment has on preterm infants in terms of their neuropsychological development and sleep patterns. Consider the longer term implications, and the measures that can be taken to minimise or overcome these.

There are four theories of why humans sleep these theories are the Inactivity Theory, Energy Conservation Theory, Restorative Theory, and Brain Plasticity Theory. There are multiple mysteries about the human body that scientists have not figured out some of these are appendices, cells, and hair growth but, there is a particular one that is very intriguing out of all these and that is why humans sleep. The Inactivity Theory is one of the oldest theories out of these four theories and the principal behind this theory is that it derives from animals using sleep as a survival technique. This theory used by animals was considered to decrease the chances of conflict and death because during periods of vulnerability such as night being a sleep made less accidents, noise and chances discovered by their predators. This theory could be false though because instead of sleeping and being unconscious the prey could stay awake and remain silent and

The average person need around seven or eight hours of sleep. We go through five stages of sleep, if you include REM. Each stage of sleep lasts a couple of minutes, and continues to route from stage to stage throughout the night. As a person transitions to a deeper stage of sleep the wave pattern is slower and more regulated. Rapid Eye Movement, also known as Rem sleep, is the stage of sleep where most of dreams take place. For many of us sleep is just another part of the day, but there are many diseases that make finding sleep for others very difficult. Insomnia is one of these diseases, and it causes a person trouble finding or staying asleep. Sleep Apnea is possibly one of the most serious sleep disorders, because it causes stop while a

My roommate has been coming into my dorm at all hours of the night and disrupting my sleep. I am going to describe a typical nights sleep cycle and describe how sleep deprivation impacts my ability to learn and my health.

If you have a roommate that comes back to your room at all hours of the night, this can severely affect your life as a whole. Sleep is essential to the human body performing in a variety of tasks. If you are constantly being woken up at various times throughout the night, it can have negative consequences on your impact to learn and your health. So what does a typical night’s sleep schedule look like?

Officers are said to be there to protect and serve members in society. Whenever there is a robbery, or accident the police is called in to perform their duties and even those beyond their call. Police officers, because of the stressful nature of their job are more often than not faced with an inadequate amount of hours of sleep. Interruptions of the sleep cycle is said to have account for many of the physiological illnesses experienced by individuals (Prather, Bogdan & Hariri 2013) and (Ratna & Sud 2008). The Restoration Theory developed by Oswald (1966) also emphasized the importance of sleep for the proper functioning of the body.

Sleep is needed in everyone’s life because the body and mind need to rest in order for you to function fully. Sleeping disorders are common in many people life, according to the book “there are about 81 different types of sleeping disorders” (Engdahl, 18). Most people do not get the recommended eight hours of sleep because their schedule does not allow them to sleep, it is recommended to create a sleep cycle so that your body can adapt to the time you are awake and shut down for the hours that you are sleeping. Studies have shown that not getting enough sleep can cause obesity, depression and even heart disease. This disorder is uncontrollable because it can come from genetics. Another reason why it is uncontrollable, some people have night terrors which occur while you are asleep. Not controlling your thoughts and waking up to a scary dream or thought, depending on their reaction it can cause them a stroke, heart attack or they might pass out. When you hear someone snoring you often take it as a joke and you laugh at the person because of the obnoxious sound coming from them, while they don’t know that they are snoring. Snoring is a common symptom in some sleep disorders, snoring can have risks on a persons sleep because it can clog your throat and nose and you could choke in your sleep and never wake up. Some sleep disorders can be treated, some people don 't ever realize that they have a sleep disorder. This disorder has many effects some which can change a person
