Sleep is Part of Life

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.

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

According to the Division of Sleep Medicine at Harvard Medical School (2007), if one does not receive an adequate amount of sleep one may become sleep deprived, one’s health may decline, the immune system may be compromised, and the ability to learn or complete tasks may become impaired. The question evoked from this necessity is, why do we sleep? Psychologists typically take two stances concerning this controversy: an adaptive stance or a restorative stance. While psychologists are still not certain on the answer, both the restorative and adaptive approaches have strong evidence of truth and actuality. Supporters of the adaptive theory of sleep believe that sleep is a result of evolution (Ciccarelli, 2015, p. 141).

Sleep is a state of altered consciousness, characterized by certain patterns of the brains activity and inactivity. An altered state of consciousness is when a person is not completely aware of their surroundings. Some researchers believe that we sleep to clear our minds of useless information. Other people believe that it is a type of primitive hibernation: we sleep to conserve energy.

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.

I’ve been thinking about sleep ever since reading Maria Konnikova’s fascinating, three-part series for The New Yorker on sleep. And then my wife, Crystal, read the series, which got us both thinking about it, and talking about it, and experimenting with it.

Everyone knows what sleep is but do they know what it really is? Sleep by definition is the process in which humans and other animals periodically rest, with greater or lesser degrees of unconsciousness and decreased responsiveness to the surrounding world. With the mentioning of consciousness, it is known that our brain is still active while we sleep and has its own biological rhythm. This rhythm includes four distinct stages that repeat

Sleep is an altered state of consciousness. Consciousness, modern psychologists believe, is an awareness of our environment and us. Sleep is the tendency to think of rest. When people get tired they want to close their eyes, lie down and sleep. What is the reason we do this? The human body requires long periods of sleep in order to restore and rejuvenate. When the body sleeps it helps to grow muscle, repair tissue, and structure hormones.

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.

Sleep is a natural periodic state of rest for the mind and body. When you sleep your eyes are usually closed and you are not moving as much as you would if you were awake. Everybody needs sleep to keep them going throughout the day.

The brains electrical activity is able to be measured with an electroencephalograph (EEG). The EEG measures your brain activity or brain waves. When you are awake and alert you exhibit beta waves which are small and fast, but immediately before sleep and when you are relaxed and allowing your mind to wander you exhibit alpha waves, and during deep sleep there are large slow waves called delta waves (2). It resulted in major leap in what was known about sleeping. The first phase of modern sleep research is roughly considered to be 1928 through 1953 (1). A lot of new information about sleeping was gained during this time period.

According to the Oxford dictionary, sleep is a condition of body and mind in which the nervous system is relatively inactive, the eyes closed, the postural muscles relaxed and consciousness is practically suspended. Sleep typically recurs for several hours every night. It is made up of two states, rapid eye movement (REM) and non-REM (NREM) sleep that alternate in a repetitive cycle across a sleep episode (Carskadon & Dement 2011).
