Why Do We Sleep Essay

Sleep contributes to an individual's well being by our body producing extra protein molecules while we're sleeping that helps strengthen our ability to

sleep is essential for our health and wellbeing. It allows our body to rejuvenate and restore itself. It helps the body to create new cells. Sleep deprivation is one of the biggest causes of premature aging. Tiredness can significantly affect your mood and how you feel. Sleep can help lower blood pressure and elevated levels of stress hormones. Your cardiovascular system is constantly under pressure and sleep helps to reduce the levels of stress and inflammation in your body. High levels of "inflammatory markers" are linked to heart disease and strokes. Sleep can also help keep blood pressure and cholesterol levels (which

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.

Thesis: Sleep plays an essential part in a person’s health and well-being; the way we feel while awake is dependent upon what happens to your body while asleep.

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.

Oswald’s study on the restoration theory of sleep attempts to explain why animals sleep. Oswald suggests that sleep is the time when the body removes waste, replenishes its levels of neurotransmitters in preparation for the next day and carries out repairs to damaged cells and growth could occur. In regards to Oswald NREM is a time for replenishing the body , especially stages 3 and 4 which occur at the start of the night when the body is the most tired. During stages 3 and 4 we secrete greater levels of growth hormone in the blood which helps in the repair process, seeming to offer support to his theory.

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).

If you want to feel energized and healthy, and to avoid hypertension, depression and sickness you have to have a good night’s sleep. Your brain and body need sleep to function, support you during the daily activities and to keep the function of all the bodily systems in order.

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.

Why do we sleep is an age-old question. Scientists have studied sleep and its purpose for many years. They have conducted countless amounts of studies and have performed many experiments. Despite scientist’s efforts, there still is no concrete answer to this question. But there are several theories that might shine a light on why we sleep. Some of the possible theories to this are the brain plasticity theory, the restorative theory, and the information consolidation theory.

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.
