Theories About Sleep

Sleep is important for our health and well-being. Extensive research has been done on the effects of sleep. These studies consistently show that sleep plays a vital role in promoting physical health, longevity, and emotional well-being. This explains why, after a good night's sleep, we feel better, our thoughts are clearer, and our emotions are less fragile. Without adequate sleep our judgment, mood, and ability to learn and retain information are weakened.

Introduction: I’m sure everyone likes sleep. Everyone needs sleep to keep the least bit active through out there day. Sleep is an important factor for your body to restore energy. Sleeping is a time to rest your body from all the hard work you have done. It is relaxing so deeply that you lose consciousness of your surroundings.

“Why do we sleep?” is a very popular questions that many humans ask today. Sleep is very sufficient to the human body. If it was not important, then God would not have designed for a third of our life to be occupied by sleep. During this time period, many people are interested to know what is a good amount of sleep and what are the harmful effects to not getting enough sleep.

There have been many experiments performed trying to find the correlation between sleep and memory. One of these experiments has showed that different stages of sleep has different effects on memory for instance, not only has sleep been seen to combine new memory with old long-term memories, but also helps stabilize memory (Born & Rasch, 2013). Using the Memory Interference Test (MIT), Amir conducted an experiment to further confirm the conclusion that the sleep improves a person’s memory. The experiment compared the amount of correctly remembered pictures by a sample people who had eight hours of sleep compared to a sample with only four hours of sleep. The hypothesis is that there is a correlation between the amount of sleep a person

Foster states, “Essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night.” Foster also explains that “Within the brain, a whole raft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways.” I agree with Foster’s first explanation of why we sleep. Sleep helps repair and renew tissue and nerve cells, the neutralization of neurotoxins, and the restoration of normal levels of chemicals throughout our bodies. Sleep can also heal the body physically. For example, it can heal wounds, strengthen the immune system, and increase growth hormone levels in the

Sleep is a beautiful thing, but people do not get enough of it. It is a time for the body to rejuvenate and process the events of the day. Sleeping is something that we seek out. Getting the recommended amount of sleep allows our body to function properly the next day. Without it, there could be detrimental consequences. The National Institute for Neurological Disorders and Stroke says that without sleep, neurons could be “polluted with byproducts”. In severe cases, people who get very little sleep often experience mood swings, hallucinations and cells do not continue to reproduce.

This article explains the importance of getting the perfect amount of sleep at night. The idea that sleeping for less than five hours or more than nine hours proves to have a negative effect on the human body. Sleep deprivation has a closely related link to memory retention and can cause a person to have trouble with daily task. The author continues to explain that not only is the brain effected by too little or too much sleep, but the rest of the body is also effected. Conditions such as high blood pressure, diabetes, and even depression have links to not getting the perfect amount of sleep. The article concludes with listing tips to get the ideal amount of sleep at night, such as, going to sleep and waking up at the same time every day and limiting the amount of caffeine that is consumed throughout the day.

Sleeping is where the brain rests, however sleep is an active period in which a lot of important processing, restoration, and strengthening occur. The brain needs time to process all the information, the less time the individual sleeps the brain is having a harder time to process information. When people are sleeping the brain goes through and sees what is important to gain or to lose information, even what has happened that particular day. The brain stores the information during sleep. It is important to get as much sleep possible.

This essay focuses on evaluating three functions of sleep. These functions include mental health (Jackowska et al, 2011), cardiovascular disease (Kronholm et al, 2011) and memory (Hu et al, 2006). The key aspects are explained in detail with regards to studies. The findings from the studies will help justify the function and it’s involvement with sleep. Sleep is important for an individual’s well being, survival, brain development, emotional regulation, cognitive function, memory, and in order to protect mental and cardiovascular health. An individual should sleep for 6-8 hours. A recent suggestion by the American Academy of Sleep Medicine recommended that an individual should sleep for minimum 7 hours. The quality of sleep is significant to maintain healthy brain functions. Evidence, indicating that good sleep quality is essential for mood and health then duration (Chandola et al, 2010). The researches implied will enable the understanding of the functions of sleep and evaluate the evidence of each of the functions, including advantages and limitations. Furthermore ethical issues are discussed, and an overall summary of the essay is briefed.

An abundance of research has been generated on sleep and why it occurs, with results suggesting that dreaming may partially explain the phenomenon. Though results have failed to discover the primary function of sleep, they have unveiled dreaming as a secondary function, which despite not being fundamental for survival possesses a great deal of utility nonetheless. While the primary function of dreaming, much like the primary function of sleep, remains ambiguous; a number of theories and empirical studies have proposed secondary functions relevant to waking life. The threat simulation theory, for example, postulates that dreaming serves an evolutionary function, thought to have heightened survival and reproductive success in the Pleistocene era. The theory purports that dreaming allows for an endogenous simulation of potential threats, which rehearses the cognitive mechanisms necessary for threat perception and avoidance in reality (Valli, Revonsuo, Pälkäs, Ismail, Ali, & Punamäki, 2005; Arnulf, Grosliere, Le Corve, Golmard, Lascols & Duguet, 2014). Additionally, the continuity theory posits that dreams mirror waking life experiences, thus serving a predictive function. In accordance to this theory, dream imagery can be used to predict wellbeing, and diagnose depression and anxiety (Miller, DeCicco, Fox, & McCourt, 2015; DeCicco, Lyons, Pannier, Wright, & Clarke, 2010; Michels, Schilling, Rausch, Eifler, Zink, Meyer-Lindenberg, & Schredl, 2014). Lastly, dreams have a

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.

The repair and restoration theory of sleep provides a strong explanation for the importance of sleep. This theory explains that sleep is essential for the restoration of body and mind processes in order to keep them healthy and

The behavior change I decided to focus on is: getting more sleep every day. For this, the article I chose is: Why Is Sleep Important. Sleeping plays a key role in maintaining a healthy life as it affects our mental activities, as well as physical health. When we sleep, the same as when we are awake, we tend to process information outside our conscious awareness. Whenever we are asleep, we may think our brains turns off but it is always still active because of the biological rhythm that is has. Having enough sleep helps us humans, and living things in general, ameliorate our immune system and gives our neurons time to repair themselves. Another benefit of sleeping enough is the fact that it helps rebuild the memories that may have faded, it reactivates them. Sleeping boosts your creativity. In fact, people who sleep on a task after having worked on it, tend to solve difficult problems more effectively. It also supports growth by releasing a hormone that is necessary for muscle development.

Why is sleep so important to us? There have been studies done that suggest that sleep deprivation can be detrimental to or decrease the function of our immune systems. Just think, how often was it that after many days of continual sleep deprivation did you start to think that you had a cold? Sleep deprivation can also result in a decrease in core body temperature, decrease in the release of growth hormone, and possible cause an increase in heart rate variability. Sleep also seems to be important in order for our nervous system to work properly. Without sufficient amount of sleep, our behavior and our ability to do things are impaired. We feel drowsy and are unable to concentrate after not getting enough sleep. With enough sleep deprivation, it has been found that some begin to hallucinate and develop mood swings. Higher-ordered cognitive task become more difficult to do where it has been shown that tests that require speed and accuracy have lower results compared to those that are not sleep deprived. Judgment is also impaired; it has been tested that riskier behavior is more likely to occur when sleep deprived. (2).This is part of the reason why you should not drive when you are sleep deprived. Aside from the risk of falling asleep at the wheel, since judgment is
