Sleep is not uniform, but a typical night 's sleep cycle is comprised of four stages. We can identify these stages based off electroencephalogram, which monitors brain waves and patterns. Stage one is a state of sleep where your eyes are closed and it is light, but if aroused they person may say they were not in fact sleeping. Stage two consists of a light slumber and the muscles begin to relax as well a decrease in heart rate. Additionally, the second stage can see a result of lowered body temperature and the beginning of the process to prepare for deep sleep. The following stage is three which entails deep sleep. Deep sleep is a heavier version of sleep and are named delta or slow wave sleep formations. The third stage is a continuation into stage …show more content…
Another theory, the circadian rhythm theory, suggests that we sleep to keep our bodies safe and protect it from physical harm. A third theory, memory consolidation view, states that we retain memories better in our sleep as well as construct an improved long term function. So, if my roommate was to disrupt my sleep cycles regularly I would have deficient energy throughout the day. I would feel constantly tired and my mental state would be working at a less than efficient level. My cognitive function would decline and my memory would not be able to retain new information nearly as well. I might be less imaginative or creative because a lot of idea come from sleep and more specifically from REM, but if I never reach REM then that would dwindle. If the lack of sleep makes me tired the following day my attention span, concentration, reasoning ,and problem solving will be affected. Therefore, my ability to learn will be severely impacted because my learning relies on those function previously stated. Additionally, I could develop various conditions as a result of sleep deprivation such as depression, anxiety, and insomnia. All of these would affect my learning capabilities and take a toll on my

According to David Myers, author of Myers’ Psychology for AP, he details that there are “five main” stages of sleep everyone experiences at night. The stages of sleep play a distinct role in our circadian rhythm, the twenty-four hour cycle of living beings physiological processes (Myers 226). In order to have a full understanding of sleep, it is essential to be able to distinguish between the following stages of sleep: light sleep, sleep spindles, deep sleep, and rapid eye
There may be many topics that have a positive and negative effect on the person or thing, but in the case of lack of sleep, it only has a negative effect. It is because sleep has been important for one to regain one’s energy. If one would lessen one’s estimated hours of sleep, one would eventually experience the negative effects that lack of sleep brings. Sleep is the only way for one to be able to rest their body, especially the nervous system. Negative Effects of Lack of Sleep on Academic
During a typical night’s sleep cycle, there are several stages of sleep: N1, N2, N3, and N4. If people are sleep deprived, they will experience negative impacts on their ability to learn and their health. To began, the first stage of sleep, N1 (NREM Stage 1), is light sleep. As theta wave activity increases and alpha wave activity fades away, people are said to be entering N1 sleep, or light sleep.
There are four stages in which you sleep in, and then REM (rapid eye movement). These four stages consist of Stage 1,2,3,4 and then REM. In each of the stages, you fall deeper into sleep, and it’s an ongoing cycle. Stages of 3,4 and REM are
They have three main types of sleep patterns you have; Monophasic, Biphasic, and Polyphasic. The first sleep pattern is Monophasic. It is when a person has one sleep per day. You would have to sleep around eight hours per night. Second sleep pattern is Biphasic.
Psychologists have found that with lack of sleep comes ill-functioning long and short-term memory, and mania. When our memory becomes shot, our ability to do some complex tasks and to learn new skills becomes much harder than if we were to get enough sleep. If you are a student who stays up till 4 am to write their paper, to study for the big exam, or to complete a project, you could even experience a slight form of insanity. Some of the symptoms of insanity, or mania, include: psychosis, paranoia, aggression, and hallucinations. This was very clear in my friend Ben, who took all honors and advanced placement exams.
Stage 1, when the body begins to enter theta, which is still a relatively light period between being awake and asleep. Some people fall asleep after 7 minutes and others sooner or longer. Stage 2, when the brain begins to produce very short periods of rapid, rhythmic brain wave activity known as sleep Spindles. Also, the body temperature begins dropping and heart rate starts to calm
During this stage, respiration becomes shallow and muscle relaxation occurs. The stage is associated with the feeling of falling , and accompanied by a reflex response such as jerking of arms and legs. As the person progresses into stage two, the theta waves become intermingled with sleep spindles and complex waves. Sleep spindles which can be measured by EEG signals, arguably define the beginning of actual sleep since the person is oblivious to most external stimuli. This stage last’s from 10 to 20 minutes.
Without the recommended full 8-10 hours of sleep, you can have lots of short and long term health problems. Including increased stress, disturbed mood, the ability to not concentrate, high risk for diabetes and breast cancer, high blood pressure, decreased immune function, major depression and obesity. These are just a few of the major health risks that come with skipping out on sleep. Studies have shown that not getting enough sleep can hurt your immune system health. This is because while you sleep, the immune system releases proteins called Cytokines.
Lack of Time The lack of time to sleep commonly occurs when the time to sleep is consumed by doing certain tasks, like accomplishing certain projects and research papers, reviewing for the examination the next day- for students, this could also occur to those who are working such as those who are working during the night time or the night shifters. Sleep deprivation of this like is difficult to cure and address, since they are required to do those task However, they should be aware of the negative effects it causes or body. Medical
These long hours and minimal amount of sleep can be associated with learning, judgement, and memory impairments. Knowing the symptoms, effects/ risks, and management of sleep deprivation can help nurses and physicians address and be aware of the problem early on. Symptoms of Sleep Deprivation There are many symptoms that can be observed in someone who is sleep deprived.
Is homework good or bad? Studies show that kids who have so much homework do just as well as kids that don’t get any homework or they do worse. In my opinion homework is causing more problems than it's helping. I think that homework is bad because it takes kids away from activities and it is bad for their health. To start, homework is taking kids away from activities and making them unhappy.
Stage one, called light sleep, lasts about five minutes. Stage two, or the onset of sleep, last thirty to forty minutes. During stage one and stage two, your brain waves slow, and your heart rate and body temperature drop. People can easily wake during these stages. Stage three and stage four are deep-sleep stages.
The effects of sleep deprivation can be separated into two parts, the short term and the long term. Mood, learning capacity, making judgement, risk of accidents are affected by the lack of sleep in the short term. The long term effects however, can lead to severe illnesses and even early death.(Harvard Medical School, n.d.) Previous researches already have shown that sleep deprivation, be it in acute total or chronic partial, has a negative impact on attention and working memory. Total sleep deprivation limits cognitive abilities of a person.
