Repair And Restoration Theory Of Sleep Essay

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.

One of the question that will be answer in my essay is why we sleep? Is it because of an ancient survival instinct we have? It very well could be however another explanation for why we sleep is based on the belief that sleep is for our bodies to restore what we lost in the body while we were awake. It is thought to provide the body with the rest it needs in order to repair itself. We have been able to gather information about sleep due to human and animal study and research alike. One of the things we have learned from animal research is that the animals who are deprived of sleep start to have their immune system deteriorate. We can support this claim because of the findings of the hormones that are released. One of the other positive aspects of sleep is that when we

“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 are a few factors that are essential for life such as breathing or eating, but one of the most essential factor is sleep. Even though the amount of sleep people need differs from one individual to another, the fact is that eventually everyone needs to sleep. People know the importance of sleep, but due to the increased workload and the pressure of society people are getting less sleep. As a result, there has been an increase interest on the effects lack of sleep has on the mind especially the memory of a person. Many questions arose about the relationship between sleep and memory due to the fact most high school and college students have become sleep deprived. For example, does more sleep mean higher grades?

The two general approaches taken by theories of sleep is both restoration and evolutionary theories. Restoration theories suggest that sleep exists in order to repair and restore the body. While the evolutionary theories that relate sleep ability to survive in a hostile environment.

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 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.

Restorative theory of sleep is brain restorative and adaptive theory of sleep is body restorative.

Sleep is a curious function in almost all living things, however, some animals don’t sleep, some hibernate, and others have a constant cycle of sleep. The field of evolutionary psychology tries to explain this phenomenon. There are several hypotheses concerning the human sleep cycle. Some suggested adaptive reason from Psychology are the following: like bears in hibernation, we sleep to save and replenish resources; we sleep in safe places to reduce risk from predators in the night; finally, we may sleep to increase cognitive function. (Psychology, 2014) However, humans are not the only species adaptions seem to evolve for adaptive reasons.

Thesis Statement: Sleeping is a positive attribute, which gives you a better chance to be productive and live a healthier lifestyle.

The restoration theory purpose that sleep is able to repair and restore the body and also our brain from exhaustion. Oswald(1980) created the restoration theory and Horne(1988) came up with an extended version of the Oswald’s restoration theory.

 Restorative Theory: the theory of sleep that states that we sleep in order to replenish the processes of our minds and bodies that are depleted during the coarse of everyday life.

Biologists, Psychologists and Therapists have been trying to inaugurate a treatment for insomnia which has a negative effect on sleep. Deep sleep aids a “major biological restorative function” as it renews our physical energy. The issue is that insomniacs don’t sleep enough and that means they lack physical energy. (2)
