Doctors have been saying for years that you should not stay up late, or not to sleep in during the day. Doing these things can lead to dementia, heart disease, and early death. One part of sleep is actually found to be more important.
Rapid-eye-movement (REM) sleep, is found to be extremely important. REM sleep is when dreaming occurs. This sleep helps make people less prone to developing PTSD (post traumatic stress disorder). Scientists believe the REM sleep has many benefits and the lack of this is why many people are suffering from many different problems. Since REM sleep only happens at the last few hours of sleep, you need to be asleep for a while. Benefits of REM are that people can better read people’s emotions. Getting enough REM sleep
can help people have less traumatic reactions to traumatic things. You should sleep the recommended 7 to 8 hours of sleep per night. If you don’t, well you may be more emotional to things that you react to, or even possibly get a heart disease. So sleep, that is all that I ask. I liked this article because it informed me that I should get a certain amount of sleep each night. It is funny, because I am staying up til 10:30 at night to finish this assignment. Well I will get to sleep now and will not sleep in in the morning.
All mammals exhibit Rapid-Eye-Movement, or REM, sleep, and yet on certain levels this type of sleep would seem to be disadvantageous. During REM sleep, which is when most dreams occur, the brain uses much more energy than during non-REM (NREM) sleep. (1) This "waste" of energy coupled with the increased vulnerability of this state on account of the body's paralysis at this time suggests that there must be a very important reason, or reasons, for the existence of REM sleep and in extension of dreams. Determining the function of dreams, however, has proved very problematic with many arguments which directly oppose each other. Some of the primary functions of dreaming have been tied to is role in development, its production of neuro-proteins, and also to how it may allow for the "rehearsal" of neurons and neuronal pathways. The influence of dreaming on learning is one of the hottest debates. Some argue that dreams aid in learning, others that dreams aid in forgetting, and yet others that dreams have no effect on learning or memory. That REM sleep seems to aid in development might argue that REM sleep may be connected to learning. It seems that most scientists believe that REM sleep aids in certain memory consolidations although some argue that it actually leads to "reverse learning.
Five prisoners had hallucinations, started screaming, and ripping their flesh off. The gas the Russian scientists used was unknown and these side effects were unpredictable. The Russian Sleep was an experiment among prisoners to test a gas to stop them from sleeping. The Russian Sleep experiment was a real event because the building they used was a real place, the building had flowers inside the room, and there are images of a recorded room.The story was difficult to learn about because there were pieces of the story missing. The prisoners in the room stopped screaming at one point and then the scientists used the intercom in the room to try and provoke them. The scientists told the prisoner whoever would cooperate with them would have immediate freedom.
... to conduct the experiments. We also see that sleep deprivation of SWS in relation to rapid eye movement in combination with biomarkers for primary depression (Kupfer, 1976)(Riemann 2001). Palagini uses polysomnographic research includes sleep continuity, depression, and altered sleep architecture to also detect symptoms of disturbed rapid eye movement and (SWS). Renunciation of search causes an increase in REM sleep in subsequent sleep. Depression is accompanied by the increased REM seen in REM sleep latency, is decreased while the initial REM occurrences are amplified. V.S. Rotenberg and Treuer use neuroendocrine research in ghrelin and sleep deprivation as therapeutic intervention for depression activates a mental heightening effect. These topics show how various discoveries in research lead to different symptoms or variables in correlation to sleep deprivation.
Sleeping disorders are a very common thing that people face every day. A sleeping disorder is when a person is unable to sleep or unable to stay asleep when they have the chance to do so. There are many things that impact a person through out the day, causing sleeping disorders but the two most common are stress and medical problems. Stress is so common in adults and college students preventing them from being able to fall asleep and getting the right amount of sleep they need each night. Medical problems such as sleep apnea and night terrors also do the same thing and are not curable. This is not good because many people cannot perform a normal day without the right amount of sleep the night before.
We live our entire life in two states, sleep and awake1. These two states are characterized by two distinct behaviors. For instance, the brain demonstrates a well-defined activity during non-REM sleep (nREM) that is different when we are awake. In the study of sleep by Huber et. al., the authors stated that sleep is in fact a global state2. It is unclear whether this statement means that sleep is a state of global behavioural inactivity or the state of the global nervous system. The notion that sleep is a global state of the nervous system served as basis for sleep researchers to search for a sleep switch. The discovery of the sleep switch, in return, provided evidence and enhanced the notion that sleep is a global state of the nervous system. The switch hypothesis developed from the fact that sleep can be initiated without fatigue and it is reversible1. It was hypothesized that there is something in the brain that has the ability to control the whole brain and initiate sleep. Studies have found a good candidate that demonstrated this ability3. They found a group of neurons in the Ventrolateral Preoptic (VLPO) nucleus. It was a good candidate because it was active during sleep, has neuronal output that can influence the wakefulness pathway, and lesion in the area followed reduce sleep3. The idea that there is something that can control the whole brain and result sleep state supports the idea that sleep is a global state of the nervous system.
Sleep is a very active process, just like consciousness. Sleep is controlled largely by nerve centers in the lower brain stem, where the base of the brain joins the spinal cord. It is here where certain nerve cells produce chemicals, which control and regulate the two alternating states of sleep: Rapid Eye Movement Sleep (REM) and Slow Wave Sleep (SWS). REM sleep is sleep where the eyes move very rapidly. This type of sleep occurs periodically (about every 90 minutes), and occupies about 25% of sleep time. The chemical that is produced that controls REM sleep is norepinephrine, which helps regulate REM sleep and facilitates arousal in sleep. SWS sleep is a more deep, restful sleep, and is called this because the brain waves move very slowly. This sleep occurs throughout 70% of a person’s sleeping time. SWS sleep is usually associated with dreaming. Serotonin is the chemical messenger associated with sleep onset and with the regulation of SWS. The exact roles and interactions of these and other chemical messengers in orchestrating sleep patterns are not known. Significantly, however, alcohol consumption affects the function of these and other chemical messengers that appear to influence sleep.
"Sleep disorders appear to be a global epidemic, affecting up to 45% of the world's population" (Noor, et al n.p.). That’s leaving a 55% chunk of the world’s population not affected. More than 70 million people in our nation experience sleep disorders, most of whom are unaware of the impact on their daily life (Wells,Vaughn 234). Due to a large portion of people being unaware of sleep disorders’ impaction, the number continuously increases. Major sleep disorders are known to be Rapid Eye Movement(REM), Insomnia, and Obstructive Sleep Apnea(OSA). Over 80 medically recognized sleep disorders exist with insomnia, sleep apnea, snoring, jet lag, shift work, sleepwalking and restless legs syndrome being some of the most common (Wells, Vaughn 234). "Poor sleep in the general population has been shown to have a significant impact on daily function, including considerable daytime cognition dysfunction, decreased ability to accomplish daily tasks, diminished sense of success and achievement, depressed mood, and reduced enjoyment of interpersonal relationships" (Andrews, Strong n.p. 500). Sleep disorders affect a large portion of society, leading people to have a daily lifestyle of drowsiness, stress and poor productivity; treatment has increased as more people become aware of sleep disorders.
Why do we need sleep? Even the most gifted scientist on the planet don’t know the answer to this question. But, there are many ideas on why we need sleep. One reason we need sleep is because without it obesity would be an even bigger problem in this world than it already is. Obesity is the condition of being very fat or overweight. Scientist have discovered that short-term sleep can make you hungrier and make you eat more. Another reason that we need sleep is because without enough of it you will have a higher risk of getting diabetes. Diabetes mellitus is a very serious condition that occurs when the body can’t use glucose normally. Scientist have proven that too little or too much sleep was linked with a host of chronic diseases, including type 2 diabetes. Another serious medical emergency that can happen to you if you don’t get enough sleep is a stroke. A stroke is what occurs when your blood flow is interrupted to part of the brain. A stroke is a serious medical emergency that requires immediate treatment. Scientist have discovered that with a while of not enough sleep your stroke risk quadruples. Scientist have also found a recurrent sleep pattern called REM. REM is a recurrent sleep pattern during which dreaming occurs while the eyes rapidly shift under close lids. REM stands for Rapid Eye Movement. In comparison to REM there is NREM. NREM is a recurring sleep state during which rapid eye movement doesn’t occur. NREM stands for Non-Rapid eye movement.
There are also risks involved with not getting enough sleep. Most people will be very sleepy and drowsy during the day, mood and behavioral problems. and even increased vulnerability to drugs and alcohol. These things could also develop into more serious sleep disorders.
Many studies of the role of sleep are partial or total sleep deprivation studies which support Oswold’s restoration theory. One of these supporting studies was Dement’s. He deprived participants of REM sleep and consequently found that they increased their number of attempted REM stages from 12 to 26 over 4-7 nights. During their first uninterrupted night, participants increased their REM sleep by 10% which is known as REM rebound. This suggests the importance of REM and the possibility that the purpose of sleep is to get into REM sleep. The participants reported anxiety, irritability and difficulty concentrating which shows that REM sleep is needed to avoid these affects and enable brain recovery which corresponds with Oswold’s theory. Even so, Dement’s study has low ecological validity, it has low population validity because there were only 8 participants and they were a self-selected sample. Participants would probably have shown demand characteristics because the experiment took place in a lab. It also has low mundane realism because people would not usually sleep in a lab and be interrupted repeatedly.
It’s very important that people know how much sleep they need. Sleeping improves people’s health while lack of sleep causes detriment
Sleep disorders are an underestimated public health concern considering that fifty to seventy million Americans are affected. Technological advances in the field of sleep have facilitated various theories to explain the need for and the purpose of sleep. Scientist have uncovered many types of sleep disorders such as insomnia, sleep apnea, and narcolepsy. Sleep disorders affect men ,women, children, the elderly, and the obese in different ways. Factors such as the number of children and the effects of menopause have been studied to determine their effects on sleep. Various treatments have been utilized ranging from non-pharmacologic to pharmacologic methods. Scientist have pinpointed areas of the brain that are involved in sleep deprivation and hormones that ultimately affect sleep.
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
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.
These in turn can cause weight gain in adolescents and may take the form of cardiovascular diseases in adulthood. I will also shed light on some of the other long- term health effects of sleep deprivation such as type 2 diabetes, chronic kidney disease and gastrointestinal disorders. I will also point out that sleep disruption may also be associated with the increase in the risk of certain cancers and even death. This is because excessive exposure to light at night decreases production of melatonin (sleep hormone) which can lead to acceleration of tumor growth, that may have carcinogenic
