The average human sleeps 229,961 hours, or one third, of his or her lives. Infants sleep about 16 hours a day, teens sleep an average nine hours a day, and adults seven-eight hours a day. We are told sleep makes everything better. Why do humans need sleep? What goes on in our body when we sleep? There are many different reasons why humans need sleep such as to regain our mental conditions, muscle tissue gets restored, and sleep strengthens our memories.
Scientists have found the ultimate sleep pattern. As a human starts to relax, they enter stage one, where the brain waves are somewhat low and fast. This is the stage where you are half asleep-half awake. Normally people who go into this stage bob their head if they are sitting or standing up. Stage two starts to occur right after Stage one. In this short stage, human slow brain waves can last forty to sixty minutes. Next comes REM sleep, which means rapid eye movement. While you are asleep, the eyes start moving around rapidly and uncontrollably.

A person's total muscle tone reduces down to zero during REM sleep. This REM sleep repeats every ninety minutes, until the person wakes up. (Pilcher) The average human needs at least 8 hours of sleep a night.
Sleep is an important anabolic process. Enough sleep restores energy. Sleep helps people function quicker and helps people be aware and fully energized. During sleep, your muscle tissues are rebuilt. There is also a hormone produced when people sleep that helps children grow, but it’s also important for adults. Sleep also affects someone's mood and personality. Also, while someone sleeps, their memories are strengthened. (Msnbc). Sleep actually spark a change in someone's brain and helps improve the memories, strengthening the cells of that part of the brain. Sleep also helps us be creative with new ideas and can enforce a person to learn something new while they sleep. (Improve). Not getting enough sleep can result in inflammation. Inflammation causes disease, stroke, diabetes, arthritis, and premature aging. People who have less that six hours of sleep a night are more likely to have higher blood levels.
(11) Children and teens who have sleep disorders, such as apnea and interruptions in breathing, have a higher risk of not paying attention in school and having lower grades. This also happens to college students. The students have lower grades than the ones who do get enough sleep. Getting enough sleep also plays along with keeping a healthy weight. Research shows, those who sleep more, lose at least 56% of their total weight loss. Those who don’t sleep a good amount of time, lose muscle mass. “Sleep and metabolism are controlled by the same sectors of the brain. When you are sleepy, certain hormones go up in your blood, and those same hormones drive appetite," Says Dr. Rapoport. (11) “People say, 'I'm going to sleep now,' as if it were nothing. But it's really a bizarre activity. For the next several hours, while the sun is gone, I'm going to become unconscious, temporarily losing command over everything I know and understand. When the sun returns, I will resume my life. If you didn't know what sleep was, and you had only seen it in a science fiction movie, you would think it was weird and tell all your friends about the movie you'd seen. They had these people, you know? And they would walk around all day and be OK? And then, once a day, usually after dark, they would lie down on these special platforms and become unconscious. They would stop functioning almost completely, except deep in their minds they would have adventures and experiences that were completely impossible in real life. As they lay there, completely vulnerable to their enemies, their only movements were to occasionally shift from one position to another; or, if one of the 'mind adventures' got too real, they would sit up and scream and be glad they weren't unconscious anymore. Then they would drink a lot of coffee. So, next time you see someone sleeping, make believe you're in a science fiction movie. And whisper, 'The creature is regenerating itself.” - George Carlin
Sleep is necessary in order for the body to rest, and is a state of decreased consciousness and lowered metabolism. Sleep is very important for all living things. Getting a sufficient amount of sleep has numerous positive effects on humans. In humans, there are five main stages of sleep. As the brain passes through each stage, the frequency of waves slows down. The amount of sleep required for humans varies depending on age. Sleep is vital for the well-being of all living things because it improves both physical and mental health. Humans just can’t get enough of it!
Why do we need sleep? Even the most gifted scientist on the planet don’t know the answer to this question. But, there are many ideas on why we need sleep. One reason we need sleep is because without it obesity would be an even bigger problem in this world than it already is. Obesity is the condition of being very fat or overweight. Scientist have discovered that short-term sleep can make you hungrier and make you eat more. Another reason that we need sleep is because without enough of it you will have a higher risk of getting diabetes. Diabetes mellitus is a very serious condition that occurs when the body can’t use glucose normally. Scientist have proven that too little or too much sleep was linked with a host of chronic diseases, including type 2 diabetes. Another serious medical emergency that can happen to you if you don’t get enough sleep is a stroke. A stroke is what occurs when your blood flow is interrupted to part of the brain. A stroke is a serious medical emergency that requires immediate treatment. Scientist have discovered that with a while of not enough sleep your stroke risk quadruples. Scientist have also found a recurrent sleep pattern called REM. REM is a recurrent sleep pattern during which dreaming occurs while the eyes rapidly shift under close lids. REM stands for Rapid Eye Movement. In comparison to REM there is NREM. NREM is a recurring sleep state during which rapid eye movement doesn’t occur. NREM stands for Non-Rapid eye movement.
Sleep is defined as a period of reduced activity in which an individual’s response to his/her environment is decreased (Healthy Sleep, n.d.) The body undergoes fluctuations in brain wave activity, breathing, heart rate and other functions. These changes occur during two main stages of sleep. Rapid eye movement (REM) sleep is the stage in which dreaming typically occurs and absorption of newly learned information takes place. The deep restorative sleep known as slow-wave sleep consolidates memories (Healthy Sleep, n.d.) Recent studies have found that some individuals may not experience both stages of sleep. This can contribute to problems in learning, memory and brain restoration.
Sleep is one of our basic needs to survive and to function in day to day operations, but not everyone needs the same amount of sleep. Some people can survive on very little sleep, i.e. five hours a night, and some people need a lot of sleep, to the extend that they are sleeping up to 10 to sometimes 15 hours a night (Nature, 2005). According to Wilson (2005) the general rule states that most people need from seven to eight hours of sleep. The deprivation of sleep in our society in continually increasing with the demands in society increasing work loads, the myth that a few hours of sleep is only necessary to function properly and that sleep is sometimes considered as killing time (Nature, 2005). Sometimes sleep deprivation is also caused by other situations like sleep disorders, i.e. sleep apnea, chronic insomnia or medical conditions such as stress (Wilson, 2005).
the sleeper will gradually descend deeper into sleep, becoming more and more detached from the outside world and progressively more difficult to awaken. Stage three is the beginning of deep sleep, occurring about thirty to forty five minutes after you first fall asleep. The deepest sleep occurs in Stage four. Stage three and four has the biggest and slowest brain wave. REM sleep, a mentally active period during which dreaming occurs, provided a biological explanation for this phenomenon. Scientists found that brain activity during REM sleep begins in the pons, a structure in the brainstem, and neighboring midbrain regions. The pons sends signals to the thalamus and to the cerebral cortex, which is responsible for most thought processes. There are several myths about sleep. For one, how much sleep a person should get? According to our text book people should sleep for at least eight hours to maintain sound mental and physical health. But every one doesn’t get the chance to sleep for that amount of time. There is no normal amount of time you should sleep. Everyone is not the same. For one I might sleep for five hours and feel refreshed enough to work another shift. Other hand my cousin might need more then eight hours of sleep to feel refreshed.
In stage one, a sleeper experiences light sleep and can easily be awaken. When a sleeper progresses to stage two, eye movement stops and brain waves become slower (National Sleep Foundation, 2015). Stages three and four are both regarded as the deepest and most restorative sleep, with no eye movement or muscle activity occurring during this stage (Stages of sleep, 2014). During these stages, blood supply to muscle increases and tissue growth and repair occurs. On average, REM sleep occurs every 90-120 minutes, approximately 4 to five times a night if adequate amount of sleep is obtained. Each REM sleep period grows progressively longer than the previous cycle, with the last episode near rise time (Hershner, Chervin, 2014). REM sleep is essential because it provides energy to the brain and the body, thus supporting daytime performance. In order for sleepers to receive the full benefit that sleeping provides, they must go through each sleep stage for an extended period of time (Stages of sleep,
(Jahnke, 2012) Sleep has many levels to it. The first level is when the firefighter (for example) slowly start to drift off into sleep. Ninety minutes after he falls asleep he goes into his first rapid eye movement (REM) period, which lasts about ten minutes. Each of the later REM stages lasts longer and longer. Rapid eye movement is when a person is dreaming.
At first, people's eyes begin to feel dry and they have trouble concentrating, causing their eyesight to weaken. Their reaction time slows down as well as their thinking process and judgment. These effects are minor but as one’s body weakens, their immune system is affected as well. This may cause their body to catch an illness or disease. Afterwards, their body becomes very weak and it will take a while before it can heal properly. In addition, their heart gets tired and cannot perform its job properly, so prolonged sleep deprivation also leads to risk of heart diseases. Not only does sleep loss make people feel tired, but it is also harmful to their body by increasing the risk of health problems (“Sleep Deprivation: What Are the Physical Effects” , Griffin R. Morgan, Mann Jeff, Peri Camille, Pietrengeelo
The four stages of sleep are REM (rapid eye movement sleep), NREM1 (non-rem), NREM2, and NREM3. During the REM stage “your heart rate rises, your breathing becomes rapid and irregular, and every half-minute or so your eyes dart around in momentary burst of activity behind closed lids” (Myers, 2014, p. 96).
There are five stages of sleep. The first stage is when one prepares to drift off. During this stage, one experiences Alpha and Theta waves. This stage generally lasts five to ten minutes. The second stage lasts about twenty minutes. The brain begins to produce short periods of rhythmic brain waves known as Sleep Spindles. Body temperature begins to drop and the heart rates slows down. During stage three, slow waves
The pilots’ performance during his job is determined on how much the pilot has rested the night before his flight. To comprehend the problem of inadequate sleep, people must know what is sleep is. Sleep consists of four stages, the first one is rapid eye movement (REM) sleep where the mind is active and some minor muscles twitch. The next three stages of sleep are where the body and mind slows down. After 45 to 75 minutes of rest, people return to REM.
Getting enough sleep can increase our chances of being more mentally/physically healthy and our safety throughout the day. How we feel throughout the day is depending on our sleep. Lack of sleep can lead to impaired judgment and actions, which can be a safety hazard towards yourself and your surroundings. When we sleep, our bodies are working to revitalize the brain to form new pathways to help with memory functions and our physical health such as healing repair heart and blood vessels and hormone balance. It is very important for everyone to maintain a good night’s rest to maintain daytime performance and lower stress. Sleep will reduce the levels of stress, help others gain control on their actions and avoid depression. Contributing to these sleep benefits will change your body and mind
Sleep is very important for human beings. Sleeping means taking rest for every person and each person spends one-third of his lifetime sleeping. Without sleeping, no one can exist in this world. Sleeping is essential for a person’s health and well-being throughout his life. Getting enough quality sleep at the right times helps all people protect their mental health, physical health and safety. A person who does not get enough sleep might suffer from mental disorders, diseases and even harmful situations. Therefore, it is important for every human being to have enough sleep.
Lack of sleep negatively affects many different aspects of your life and making sure you get enough sleep will save you from: mood swings, loss of focus, change in behavior, and difficulties in everyday tasks.
People do not take sleep as important as they should and do not get enough sleep that their body requires to function properly. Sleep is very important for a person 's physical health, well being and healthy brain functions. Without enough sleep our bodies can not perform daily function to our full ability. For many people, sometimes there is just not enough time in one day to complete all their tasks, fulfil all responsibilities and get the minimum sleep their body requires. Why do people not get enough sleep? Being a parent, student or just an adult in the working world comes with many responsibilities. People do not get enough sleep for reasons such as stress, discomfort, or medical conditions.
