The Effects Of Sleep And Variables On Sleep

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

In my paper, I will tackle insomnia from various perspectives: definitions, types, causes, effects, and means of solutions.

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).

Sleep is one of the unavoidable daily-living activities and it is one of the most important factors contributing to a person’s health. A quality sleep is essential for the physical, cognitive and psychological well-being of a person. Learning, memory processing and maintenance of the brain are among the most important functions of sleep. In addition to maintaining the brain, sleep has important roles in controlling the

Sleep is undoubtedly one of the most essential requirements for the human body to function properly. It plays a very important role in ensuring the wellness of the human body both physically as well as mentally. In fact, the importance of sleep is clear from the fact that it helps you in maintaining a good lifestyle throughout our entire lifetime. Not only does it help maintain our physical and mental health; rather it also helps in maintaining a decent and healthy lifestyle along with ensuring safety from a number of fatal diseases. It is usually said that the mood in which you wake up is largely dependent on the type of sleep you have been in. This in itself is a big proof of the importance of sleep in our lives. While sleeping, our body finally gets its share of rest and it also gets ample time in rejuvenating from all the wear and tear that it went through during the entire day. Not only this, the body is in its own working condition when we are sleeping as this is the time when it supports the healthy functioning of the brain as well as physical attributes of our body.

Sleep disorders is one of the pivotal behavior in modern times when shortage of time for oneself is often the case with everyone. The problem is far more chronic when the patient has a condition of ADHD (Attention-deficit/hyperactivity disorder). The article sums up this condition, its effect on sleep and its remedy through different medications. The article describes that sleep disturbance can be divided into four categories which are; Initiation Insomnia, Restless Sleep, Difficulty Waking and Intrusive Sleep. Then articles discuss different theories from respected psychiatrists like Myron Brenner and Thomas Brown on the causes of this type of sleep disorder. Articles progresses with a explaining different ways to remedy the situation like using bed for sleeping and not thinking bout the problems of life, sticking to a vigorous routine of sleeping as well

A recent news article on CNN, Lack of Sleep May Shrink Your Brain, cites a research study suggesting that insomnia and other reasons for sleep deprivation may reduce brain mass. Although the study was correlational, the author of the news article focuses mostly on one of the three possible relations between sleep and brain mass: lack of sleep may cause shrinking of the brain. Only at the end of article, the author mentions that shrinking of the brain may cause lack of sleep, but completely disregards the third possibility that a third variable may cause both the shrinking of the brain and lack of sleep.

Ten percent of the American population has recorded having a sleep parasomnia, most of them being young children or adolescents. Parasomnias range from very common disorders such as sleepwalking, to a few some may have never heard of, for instance: sleep paralysis. Sleep parasomnias are “disorders characterized by abnormal or unusual behavior of the nervous system during that occur during non-rapid eye movement (NREM) sleep or rapid eye movement (REM) sleep” (Parasomnias). NREM sleep (also referred to as slow wave sleep) contains more common parasomnias that involve the stimulation of the autonomic nervous system, motor system, or cognitive processes. Sleep disorders most commonly present in children and young adults but tend to resolve as the patient ages. Sleep parasomnias affect the daily behavior and lifestyle of young children and adolescents by altering their learning environment, stiffening the home life, and modifying their overall mood.

The average person sleeps around four months a year, begging the question why do humans dedicate such a large portion of our time asleep? One of the key components of sleep are dreams, many psychologists have attempted to figure out why dreams are beneficial to us, some of these theories include: Wish-fulfillment, problem solving, replay, and activation-synthesis. Through analyses of my dream, I will demonstrate that activation-synthesis is the most logical explanation as to why we dream.

Moreover, many of the claims the article makes, as outlined above, have a biological and psychological scientific basis; however, the article fails to mention the sources from which its conclusions was drawn from. That said, in this paper three differing journal articles will be presented that focus on the different processes that take place during sleep. The scientific journal articles will be analyzed and compared to the Cosmopolitan article. as summarized above.

Sleep is known as one of the most important things we as living organisms go through throughout our lives. Sleep is broken down into five stages four of which are in the NREM “nonREM sleep period” and one which is in the REM “Rapid eye movement” period (Huffman & Dowdell, 2015). There are four theories that are considered to be the reasons for why we sleep and dream those being theories are adaptation/protection, repair/restoration, growth/development for sleep and learning/memory for why we dream (Huffman & Dowdell, 2015). Sleep is important to our bodies because it helps our heart, brain, and immune system to recuperate and to rebuild after a long hard day. It is also important to us if we want to have a long lifespan (“How Important Is

NREM (non-rapid eye movement) sleep occurs during first 90 minutes of sleep and is passing time through the four stages of the NREM cycle (Feldman, 2015). All the stages of NREM sleep each have specialized sleep-wave patterns occurring to what stage of sleep one is in. Lasting only a few short minutes, stage 1 sleep is the transition period between wakefulness and sleep (2015). Many college students create the golden “winding down effect”, eyes drooping and phasing in and out of “I was not sleeping; I just closed my eyes for a little” during stage 1. The level of difficulty to awaken from sleep increases exponentially when entering stage 2 of the NREM cycle. The brain waves in this stage develop slow, regular patterns with “…momentary interruptions

For the past decades, due to its fast growing technologies and advanced living society, there has been a tremendous change in people 's lifestyles. Unlike the old times, people nowadays tend to get few hours of sleep or less than their body needs. Sleep deprivation could occur for the reason of the busy daily routines, such as: stress from work, any kind of relationships, school, and family. There are so many different areas where people get stressed and suffer through sleep deprivation, insomnia. Michael H. Silber is a highly qualified as one of the authors because he has various different degrees. He worked for many positions, such as: American Board of Psychiatry and Neurology - Sleep Medicine, American Board of Psychiatry and Neurology

Since the semester started sleep has been something that has alluded me several times. I can’t remember the last time I had a full 7 or 8 hour sleep. My sleep pattern now seems to consist of barely any naps and close to 4 or 5 hours of sleep. For this project i want to look at how i can improve my sleep patterns so that i’m getting more than 4 to 5 hours of sleep a day and if it’ll improve my work ethic as well as my health.

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
