Does The Early Bird Really Get The Worm?

There are four stages of sleep. In the first stage (10 min. into sleep), your pulse slows down and your muscles begin to relax. Your breathing

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).

During the first hour of sleep, brain waves slow down, and the eyes and muscles relax. Heart rate, temperate, and blood pressure fall as well. Over time, however, brain activity drastically increases from slow wave sleep to rapid eye movement (REM) sleep, and brain waves observed during REM are similar to those observed during waking. However, atonia occurs, which is when the body’s muscles are paralyzed, the muscles that allow breathing and control eye movements are fully active, and heart rate, blood pressure, and body temperature increase. As sleep continues, the brain alternates between periods of slow wave sleep. It’s divided into four stages. Stage 1, the brain activity is unsynchronized. Stage 2, our breathing, heartbeat, and brain activity become slower. Stage 3, our breathing, pulse, and brain activity is slower yet, and brain activity is synchronized. Stage 4 of sleep, our breathing, pulse, and brain activity is the slowest, and brain activity is highly synchronized. Brain activity is increased with each stage and brief periods of REM sleep, with the slow wave sleep becoming less deep and the REM periods more prolonged until you are woken. Approximately 20 percent of a person’s total sleep is spent in REM

 First, People go through stages of sleep there are 4 stages in all. The first stage is NREM Stage 1, this stage comes into effect when you decide to go to sleep and close your eyes, this stage lasts for about 10 minutes and you can wake very quickly therefore be fully awake. While in this stage, your blood pressure and your brain temperature will decrease. In NREM Stage 2, this comes into effect when you finish NREM stage

The brain experiences five unique phases during sleep. The fifth stage is REM sleep, which makes up one-fourth of the sleep cycle and begins after 60 minutes of sleep and repeats a few times during the night. REM sleep involves rapid eye movement, relaxed muscles and vivid dreams. During this time, when the body is extremely relaxed, major cell and tissue repair takes place. REM sleep is the ideal time for the immune system to repair the body. However, marijuana affects dreams through harmful sleep disruption.

Fifth Stage REM Rapid-Eye-Movement Sleep, while in REM breathing rates, brain activity increases and decreases, and brain waves are faster and smaller. Paradoxical sleep or active sleep refer to REM the reason for this is because brain, body become heightened and muscle movements are restrained but can twitch this is so dreams are not acted out. REM can last for up to fifteen min. From stage one NREM to REM sleep has taken about ninety min. For the rest of the night’s sleep cycle, it bounces between NREM and REM.

The suprachiasmatic nucleus (SCN) serves as the biological clock for the human body. It controls the melatonin production of the body, depending of the amount of light that fall into the eye causing the sleep-wake cycle. The human body goes through 5 ultradian sleep cycles, each approximately 90 minutes long. Each cycle consist of a number of stages going up to four; that then again reverse up to the second stage. Instead of going back to stage one, the body then enters a stage of active sleep with increased blood pressure, oxygen consumption and neural firing, as well as eye movement that resembles that of a waking person, called rapid eye movement sleep (REM). The less active stages are called non rapid eye movement (NREM) or slow-wave sleep.

Although scientists are unsure why we sleep, they do know how sleep works. There are two phases of sleep: Rapid Eye Movement (REM sleep), and Non-Rapid Eye Movement (NREM sleep). These phases help form whole sleep cycles, and a complete cycle lasts around ninety to a hundred ten minutes. If you sleep for eight hours, you will go through about five cycles every night. During these cycles, you are mostly in NREM sleep. REM sleep only lasts for about ten minutes of the cycle. However, as the night progresses, NREM sleep decreases and REM sleep increases. Every cycle of sleep has five stages. In stage one, you will get NREM sleep. You begin to lose muscle tone, which causes twitches and hypnic jerks. You also have hypnagogic hallucinations and

There are five basic stages in cycles I go thought when I am going sleep though out the night. Stage one, which lasts about five minutes, my brain waives becomes slower and irregular. Then I would go in to stage two, which lasts around ten to twenty minutes, I would have a regular EEG and less then 50 percent of this time is spent in this stage. Stage three is a short transition, which is made up of twenty to fifty percent delta waves. Stage four is around fifteen to twenty minutes, in this stage I have less than fifty percent delta waves and it is where I get the deepest sleep. Then I would cycle back through stages three and two before I enter into stage five. In stage five, which is called REM, which last ten to twenty minutes and I will

With this in mind, a person’s heart rate slows, and they begin to rest and recharge after a long day. When this person finally dozes off, they undergo cycles of non-REM and REM sleep. Non-REM sleep comes early in sleep and contains deeper, more restful sleep. Dream filled REM sleep comes late in the night and when all dreams occur. Dreams in REM sleep can last anywhere from a few seconds to forty-five minutes long. The transition between the two cycles happens at the same time for each person, regardless of bedtime. The time of this switch between cycles differs for each person. This is the reason for not forcing sleep. This results in a healthy balance of non-REM and REM sleep balance

The article by Peikoff (2015), 9 Things You Never Knew Your Body Does While You Sleep in Cosmopolitan magazine provides general explanations on the various processes the body cycles through while individuals are sleeping. The article outlines process such as the body’s tendency to lower in temperature, toxin cleanses, paralysis, neural cell repair, and immune system activation which occur during sleep (Peikoff, 2015). It goes on to outline many statistics concerning sleep apnea and its effect on life expectancy in females (Peikoff, 2015).

A normal night's sleep is when a person successfully goes through all five stages of sleeping. The first stage is when you are lightly sleeping and muscle activity starts slowing down a little. You then start slowing your breathing and heart rate down, as well as your body temperature. The 3rd stage is what is called deep sleep. Deep sleep is whenever your brain start to generate delta waves. The next stage is number 4. This stage is whenever your body is in a very deep sleep and your brain is producing delta waves. The last stage of sleep is the 5th. While in this stage a person may start having rapid eye movement. This is also the stage wear dreaming occurs. It is always important to get a good and full night's rest. Not sleeping can cause

Sleep affects the body in hundreds of ways and just to name a few, it repairs tissues, cleans the body of chemicals, and replaces neurons. After closing your eyes, you enter BREM, which stands for “before rapid eye movement,” your body slows down most bodily functions such as breathing and pulse rate to preserve energy while sleeping. The most important part of sleep is REM or “rapid eye movement,” which is the part of sleep where neurons are replaced and repaired, inadvertently making dreams. REM also completely freezes your body or well shuts down the nervous system, to prevent you from walking around when dreaming. Sleep overall is an extremely important part of life as it helps the body.

Sleep is composed of five different cycles, each cycle lasts for about 90 minutes. It is consists of two main broad stages, the first four cycles is known as non- rapid eye movement (NREM) and the last stage of the cycle is denoted by rapid eye movement (REM) sleep.

A typical night’s sleep is much more complicated than just closing your eyes and waking in the morning. As humans, we live our life on a circadian rhythm. This means that changes occur roughly based upon a 24-hour basis. This circadian rhythm plays a major role in when we get tired and decide it’s time to sleep. This rhythm is theorized to have helped us stay safe thousands of years ago. We would fall asleep during the time that their seemed to be threats roaming around in the dark. to Once we finally get to sleep, our brains and bodies are doing much more than laying in complete stillness. There are five distinct stages of sleep that we experience as we sleep. Each is uniquely different and serves a purpose throughout the night. The first stage of sleep is a very light sleep that lasts for 5 to 10 minutes. During this stage of sleep, you may not even realize that you’re sleeping. While in this stage of sleep our brains power down by 50 percent and produce theta waves four to seven times per second. We proceed to stage two after this. During stage two, our brains power down
