How the amount of REM sleep you get can change. It’s the time of night where most likely you would be dreaming. People believe one reason as a child you have a higher amount of dreams as a kid because as a child you get more REM sleep. REM sleep is part of a cycle of how you sleep so say you were woken up in the middle of the night during REM sleep you might ruin that cycle. When we are sleeping and specifically in REM sleep our brains are reorganizing itself and it is also giving itself a deep clean. There are also other things that can affect how you sleep at night like sleep behavior disorder, basically during their dreams when they are supposed to be resting there body and dreaming should be a brain activity. People with the sleep behavior …show more content…
disorder will start actually using their body including talking, kicking, hitting, sleep walking and many more. Something that I have also seen is that a lot of people say oh I’m a heavy sleeper, but one of my questions if you aren’t actually deep sleeping for very long when you sleep why don’t those people who say they are deep sleepers wake up easily? One aspect of this project the I would really like to get into is how REM sleep can affect your day and also just your whole week or life.
As you go on your REM sleep changes and makes it so you are now not in as much of a deep sleep as you use to be. When you are a baby you sleep for a lot longer than you do when your and adult. When you are a baby you sleep for 16 to 18 hour, when you are in school age you need a bout 9.5 hours and when you are and adult all you need is 7 to 9 hours it’s a big change over the years how much sleep you need to function but in the beginning if you don’t sleep more maybe your brain won’t develop …show more content…
enough. Sleep is what re-energize us, clearing the waste from our brain and body cells. Sleep also supports our learning and memory in the brain. It also plays important roles in regulation of mood, and appetite. The brain generates two different types of sleep. There is slow-wave sleep (SWS), which is a deep sleep. REM sleep is the time of sleep where you are in a deep sleep and your eyes start to move side to side a lot. Most of our sleep is of the low-wave sleep. Its determined by the slow brain waves, how the muscle is relaxed and how deep we are breathing. Which all helps the body rejuvenate. During REM sleep, the activity of the brain is similar to a person who is awake. It is during this stage of sleep that dreaming is to happen, which is proposed to be a structure to replay and process mental catalyst in order to extract meaning and create memories. The new discipline , published online today in Science, reports the discovery of a genetic mutation on the gene DEC2 that appears to allow the mother –daughter duet of "shortstop railroad tie "—and a fistful of transgenic mice—to truly need less sleep.
Sleep Deprivation Can Change Your Genes. Blood samples taken after just one week of getting fewer than six hours of sleep a night showed changes to more than 700 genes due to sleep deprivation alone, according to the study. Researchers don’t entirely understand the persona of each of these genes and what the changes may mean, Bloomberg reported, but at least some affect our inflammatory, immune and stress responses, researchers

In conclusion I believe that it is true that you have more Rem sleep as a child because as a child you have 80% REM sleep and as you get older that lowers because in adults they only account for about 20 to 25% REM sleep.
Before discussing the role of NREM and REM in learning, it is necessary to clarify the identity of and differences between the two. This type of sleep is marked by different stages based on different the different brainwaves exhibited. REM sleep differs from NREM in that most dreams occur during REM sleep although the two activities are not synonymous. REM is also marked by an incre...
Sleep deprivation in hospitalized patients can result in increased morbidity and mortality, and can lower their quality of life. Hospitalized patients require more than the average amount of sleep to aid in recovery, but often get an inadequate amount of sleep or experience poor quality sleep. There are increased frequencies of awakening or being awakened too early in the morning, difficulty falling asleep, an increased need for sleep medications, poor sleep quality, an increase in frequency of napping and nightmares. Sleep-wake cycles contribute to adequate protein synthesis and cellular division that is crucial to sustaining the healing process and maintaining immunity. Sleep deprivation changes normal circadian cycles, resu...
All children need sleep and want sleep during the weekdays and that is very difficult. It has been noticed that older students and younger students, such as third graders and eleventh graders, sleep patterns are very different. In many places it is the same way that middle schools and high school start earlier than elementary schools. The problem is that adolescents stay up at least two and a half hours later than younger children do (Bergin 2).
The REM Sleep Behavior Disorder (RBD) is characterized clinically by a history of changes in the nature of the patients' dreams
The discovery of rapid eye movement (REM) sleep suggested that sleep was not, as it was thought to be, a dormant state but rather a mentally dynamic one. Your brain is, in fact, very active in this state, almost to the level at which it is when a person is awake. Yet during this active stage in which most dreams occur, the movements of the rest of the body are completely stilled. To imagine this paralysis during dreams not occurring is a frightful image, since in many cases dreams are violent and active. When the neurotransmitters that control the movement of the body do not work properly the person develops REM sleep behavioral disorder (RBD).
...ns behind the process. Reliable sources indicate that sleep deprived individuals display a greater difficulty in performing everyday tasks compared to well rested individuals. The study also reveals that sleep deprivation is linked to obesity, depression, anxiety and the suppression of the immune system. The research conducted suggests that sleep deprivation can be recognised in adults by mood fluctuations, and difficulty in concentration, while children will tend to become emotionally explosive. The findings also detail simple lifestyle alterations available to combat sleep deprivation.
In recent years, there have been studies on beauty sleep and the perceived health, attractiveness of sleep deprived people. Researchers try to ascertain what happens to individuals when they get a good nights sleep and when they are sleep deprived. What happens to the body when it doesn’t get a full nights rest? It is known that when the body is at rest and in deep sleep, it will restore itself. If someone doesn’t get a full nights rest, they didn’t give their body a chance to repair and the person will appear to look unhealthy. "Poor sleep also equals slower cell turnover, which leaves your skin less glow-y, and can accelerate the signs of aging. In the deepest stages of sleep, your body goes into full-on restoration mode, secreting growth hormones that work to repair damaged cells. Not enough deep sleep means not enough growth hormones and not enough cell repair."(Denise) It is common knowledge that having a full nights rest has positive effects to the body, but does this positive effect also reflect according to the persons appearance? Are people able to perceive that someone is sleep deprived or not?
My paper is based on an article from the text’s web site (chapter 9) entitled “Lack of sleep ages body’s systems.” The basic claim of the article is that sleep deprivation has various harmful effects on the body. The reported effects include decreased ability to metabolize glucose (similar to what occurs in diabetes) and increased levels of cortisol (a stress hormone involved in memory and regulation of blood sugar levels). The article also briefly alludes (in the quote at the bottom of page 1) to unspecified changes in brain and immune functioning with sleep deprivation.
Sleep deprivation causes ones body to become extremely fatigued and unaware of what's happening. It can also lead to insomnia and paranoia. With insomnia you begin to fear sleep for the fact of missing something or never waking up to see the next day. Once paranoia sets in you start to act crazy and completely out of hand. Without accurate amounts of sleep the body can begin to harm itself by producing more of certain chemicals than the body needs causing serious health effects. Some of these include loss of memory, higher risk of diabetes, impaired immune system and higher risk of heart
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
At first, people's eyes begin to feel dry and they have trouble concentrating, causing their eyesight to weaken. Their reaction time slows down as well as their thinking process and judgment. These effects are minor but as one’s body weakens, their immune system is affected as well. This may cause their body to catch an illness or disease. Afterwards, their body becomes very weak and it will take a while before it can heal properly. In addition, their heart gets tired and cannot perform its job properly, so prolonged sleep deprivation also leads to risk of heart diseases. Not only does sleep loss make people feel tired, but it is also harmful to their body by increasing the risk of health problems (“Sleep Deprivation: What Are the Physical Effects” , Griffin R. Morgan, Mann Jeff, Peri Camille, Pietrengeelo
Dreams are series of thoughts, images, and sensations occurring in a person’s mind during sleep. Dreams occur during a certain stage of sleep known as REM. Several different psychologists, including Freud and Hobson, have studied dreams. Psychologists have provided many theories as to what dreams are and the meanings behind them.
Sleep deprivation can affect people of all ages, races, and ethnicities but there is a certain group of people that are more likely to get sleep
Contrary to popular belief adults, teens, and younger children do not actually need the same amount of sleep. Experts from the Centers for Disease Control and Prevention (CDC) suggest that teens, on average, need 9 to 10 hours a day while adults need around 7 to 8 hours a day. Newborns need about 16 to 18 hours a day. Preschoolers are suggested to have 11 to 12 hours, and school aged children need to have at least 10 hours of sleep per day (Sleep and Sleep Disorders). Most people think that adults need more sleep than younger children, and most of the time adults do receive more sleep than children. However, the fact of the matter is, the younger a person is the more sleep they need. Sl...
Lack of sleep negatively affects many different aspects of your life and making sure you get enough sleep will save you from: mood swings, loss of focus, change in behavior, and difficulties in everyday tasks.
