Lack Of Sleep Causes Major Changes In Physiology And Brain

The function of sleep is to promote restoration. The human body accumulates damages due to impact strain and from reactive oxygen species that damage cells and buildup during times of activity (Sleep-wake cycle, 2006). During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems (Sleep-wake cycle, 2006). Most of the body has restorative processes that can supplement the restorative processes that happen during sleep for long periods of time, but the brain is more reliant on regular intervals of sleep for restoration as quiescent restoration is insufficient (Sleep-wake cycle, 2006). When the body does not get enough sleep, most body functions work at diminished capacity. (Brain Basics, 2017). Sleep deprivation is defined as obtaining inadequate sleep to support adequate daytime alertness (Kryger, Roth, & Dement, 2005). The pathological effects of sleep deprivation can lead to undesirable physiologic

The suprachiasmatic nucleus (SCN) serves as the biological clock for the human body. It controls the melatonin production of the body, depending of the amount of light that fall into the eye causing the sleep-wake cycle. The human body goes through 5 ultradian sleep cycles, each approximately 90 minutes long. Each cycle consist of a number of stages going up to four; that then again reverse up to the second stage. Instead of going back to stage one, the body then enters a stage of active sleep with increased blood pressure, oxygen consumption and neural firing, as well as eye movement that resembles that of a waking person, called rapid eye movement sleep (REM). The less active stages are called non rapid eye movement (NREM) or slow-wave sleep.

Even though the number of hours differs for different people, the mental and emotional affects damage all. Lack of sleep effects the brain’s

On the importance of sleep, Dalai Lama quotes "Sleep is the best meditation." A sound sleep is a key to overall health. Lack of sleep affects mood, increases the risk of psychiatric disorders and depression, cardiovascular diseases and also lowers immune system health. Sleep is utmost important for our body to rejuvenate after the day's exhaustion. And as researchers acquire more knowledge about its purpose -and the adverse side effects of not getting enough- the significance of getting a goodnight's sleep becomes even more comprehensible.

As a result, of more American’s using electronics late at night, using your bed for more than sleeping, and increased anxiety has caused society to constantly lose a good night’s rest. There are many people who every now and then don’t sleep well, but there are several who experience what is called sleep deprivation: “Sleep deprivation is a condition that occurs if you don 't get enough sleep” (“What Are Sleep Deprivation and Deficiency?"). There are several dangers with so many American’s being sleep deprived such as increased chance of falling asleep while driving or even increased work injuries: “Lack of sleep exacts a toll on perception and judgment. In the workplace, its effects can be seen…accidents. Sometimes the effects can even be deadly, as in the case of drowsy driving fatalities” ("Consequences of Insufficient Sleep”). For the purpose of public safety, American’s should be aware of the dangers of sleep deprivation starting with how using electronics late at night effect

My name is Whitney Fryer and I am a Media student. For a class, I am currently working on a feature story about sleep deprivation and how it affects our bodies. I am looking for someone to interview about the topic. Would you be willing to sit down for an interview with me or could you point me in the direction of someone who would be able to? It would be very appreciated.

What exactly goes on in the brain during sleep? Nerve-signaling chemicals called neurotransmitters, control whether we are asleep or awake by acting on different groups of nerve cells, or neurons, in the brain. Neurons in the brainstem, which connects the brain with the spinal cord, produce neurotransmitters such as serotonin and norepinephrine that keep some parts of the brain active while we are awake (http://www.ninds.nih.gov/disorders/brain_basics/understanding_sleep.htm). So why do we need sleep? Sleep is important to the essence of every person. Sleep offers the brain an opportunity to sort through new and old information, to find solutions to problems, and to archive memories. One of the essential roles of sleep is to help us solidify and centralize our memories. As we go about our day, our brains take in a very large amount of information. This information is not directly recorded, it’s rather that these facts and experiences first must be processed and stored; and most of this processing happens while we sleep. The brain reinforces memory and categorizes everything learned and removes any useless information. This paper will cover how lack of sleep can be detrimental to a person. The primary symptoms of sleep deprivation that will be discussed are dangerous health issues such as cognitive dysfunction, weight gain and physical health.

Sleep is an essential, fundamental process that has been programmed in almost all life forms since the early development of birth. The importance and benefits of sleep lies paramount in comparison to other functions we do as humans including eating! Some scientist even say that you will die from sleep deprivation before you will die from food deprivation because when a person sleep your body is still very much awake and undergoes numerous functions. When health functions like memory consolidation, organ repair, neurogenesis, brain development, and muscle recovery, growth, daytime performance, and reducing stress comes to the table it makes you question yourself "Why do I even attempt to stay up at night?" Lack of sleep or sleep deprivation is widely known to cause accidents and was recorded to be the factor of some of the biggest disasters in recent history. The 1979 nuclear accident at Three Mile Island, The Exxon Valdez oil spill, and the 1986 nuclear meltdown at Chernobyl just to name a few.

One economic problem in sleep deprivation is problems with accidents caused by sleep deprivation. One example of this is in the article “Students Aren't Getting Enough Sleep—School Starts Too Early” from The Atlantic by Jessica Layhey, “‘For example, an important recent study published this spring by Dr. Kyla Wahlstrom documented the positive effects of school start time delay in over 9000 students from eight high schools in three states, including improved grades and standardized test scores and up to a 65 to 70 percent reduction in teen car accidents.’” This can show how a reduction in car accidents can lower the amount of money that is spent on things like repairs, medical treatment etc. Sleep deprivation can possibly lead to alcohol and drug abuse as stated in the Huffington Post article “5 Scary Health Effects Of Sleep Deprivation During The Teen Years” which can lead to car accidents which can go on their record possibly making it harder to get jobs in the future.

Consequences of sleep deprivation can include; decreased performance and alertness, memory and cognitive impairment, stress, poor quality of life, occupational injury and auto mobile injury

Sleep plays a pivotal role in how well the human mind functions. However, people want desperately to know everything they possibly can and therefore neglect to get a proper amount of sleep in order to maintain a healthy schedule. Studies have shown that sleep deprivation attributes to the loss of memory as well as other cognitive functions.

Sleep is essential; every living things needs sleep. Sleep is the body 's way of cleansing itself; without it our bodies could not function. Sleep has multiple health benefits effecting every aspect of our lives; sleep is so essential for the body that humans spend 1/3 of their lives asleep. Humans have been fascinated with sleep throughout history; several early scientist like Aristotle in 350 CE who formed a hypothesis that sleep was a form of physical renewal (Borel, 2014). Humans know little about sleep and see it as a inconvenience, we take sleep for granted and the repercussion of not getting enough sleep is not healthy. Sleep deprivation impacts ones overall health by contributing to multiple primary biological functions.

Firstly, we must ask ourselves the consequences of not getting enough sleep. There is the obvious first effect, which

Research from sleep studies show that people who are sleep deprived are more irritable and have a lack of concentration and creativity. This diminished capacity means a person is more prone to making mistakes at school, work or even when engaging with other people. Additionally, one could put lives at risk due to a slower reaction time when driving a car. Or, they could risk the lives of others while performing this simplest of everyday tasks. Consider this: there is a reason why the U.S. Department of Transportation changed its’ industry standards to regulate the hours of sleep required for truck drivers all over this country.

In this study the purpose was to obtain information based on sleep deprivation that can affect the memory of the brain, and also the stress hormones, glucose and inflammatory markers. This study applies to the research question, because sleep deprivation is known to affect the body in cause of stress and can cause other affects like increase in blood pressure. Stress can also be the main affect of memory loss along with glucose levels. This study was conducted at the Sungkyunkwan University School of Medicine in Seoul Korea. The subjects that were asked to participate were six healthy men ages 23 to 27 years old. All of the participants were good sleepers and did not accumulate any excessive sleeping through out the day.
