Two Main Phases Of Sleep: Non-Rapid Eye Movement

While sleeping, there are many different stages that exist throughout the process. The stages are measured by the brain waves emitted. The process is broken up into stages: 1, 2, 3, 4, and REM (“Stages of Sleep”). REM is known as rapid eye movement. The brain goes through the stages several times in a night and the REM stage gets longer as the night progresses. Many people believe that REM is linked to dreaming, explaining why dreams are usually easier to remember in the morning.

This is a short article written by a collaboration of people by a company named Today’s Science. Their main goal was to describe the pattern of sleep a human goes through during the night. This cycle is called NREM and REM, non-rapid eye movement and rapid eye movement. They mostly describe what happens during sleep because without sleeping you could not dream. Dreaming occurs during the rapid eye movement cyc

Sleep proceeds in cycles of Rapid Eye Movements (REM) and non-REM (NREM) sleep, cycling through the first for stages in intervals

Have you ever not gotten enough sleep, or cut your sleep short for a class? Show of hands? Alright, well today I will be speaking with you about a subject that is near and dear to all of our hearts. Today I will be talking about sleep, specifically about REM sleep. First off does anyone know what the initials REM even stand for? REM stands for rapid eye movement, and it is the stage of sleep in which most dreams occur. It gets its name from the way your eyes move back and forth in this stage. Though those movements are slower than how your eye would move when you are awake. During a typical night, you cycle between REM and non-REM sleep, but spend the majority of your time asleep in non-REM.

While awake, beta waves are active in the brain. The first stage is known as REM. This is where rapid eye movement occurs. As well, dreams typically occur here. As you begin to fall asleep these beta waves become less prevalent and theta waves start to develop. This occurs in the early stages of sleep. Furthermore, this stage is known as N1 which is a light sleep that usually occurs for about five minutes. During this time body temperature drops and shallow, irregular breathing occurs. The next stage is known as N2. An EEG would show sleep spindles at this point. As time goes on the brain will begin to produce delta waves. These waves are long and slow. They occur in the deepest stages of sleep known as N3. This stage is also responsible for growth hormones being released in the pituitary gland. After N3 the body will begin to wake up on its own. The body will return to it's REM stage where body temperature increases and eyes have movement.

Researchers have classified two definitive types of sleep, REM, otherwise known as rapid eye movement, and non REM and have divided the sleep cycle into four distinct stages. REM sleep is associated with dreaming as most of our dreams occur during this stage. REM waves are very fast and resemble beta waves which indicate that you are awake. REM sleep is usually

Research has found that REM sleep has evolved to become part of the dreaming process otherwise known as REM sleep-dreaming. Sleep with electroencephalographic evidence of the brain shows that a human’s brain is awake during sleep because involuntary eye movement occurs. This occurs during the dreaming consciousness every human possesses which is part of the secondary consciousness every human has. There is also non-REM sleep which is sleep that occurs without the rapid eye movement. The importance of REM sleep and dreaming has been studied for many years and has gradually become more informative. REM sleep is important for a human because it allows for developmental brain growth which furthers the evolution of humans.

Sufficient sleep is a biological necessity for the normal functioning of humans, it allows the body to rest and to replenish itself so that it is able to serve its function of living. In addition, mental and physical health depend on the amount of sleep we get. Most adults and students value work and college much more than sleep, this is due to the academic, career, and materialistic demands. Researchers have noted a positive correlation between lack of sleep and decreased physical health, mental health, and academic performance. Sleep consists of two cycles: non-rapid eye movement (NREM) and rapid eye movement (REM), which are sleep patterns that alternate throughout the night. Firstly, sleep begins with non-REM sleep lasting about 90 minutes followed by REM sleep lasting 10-30 minutes, then the cycle repeats itself. REM sleep is the most important phase of sleep because the body is internally awake, with waking-like brain activity, yet asleep and externally calm. Thus, an uninterrupted REM phase of sleep is necessary for integrating previously learned material, and giving the individual a feeling of being well rested and refreshed. Many individuals will put sleep off so that more work hours, and school work can be fit into the day in order to get a better outcome such as job promotions or better academic grades, but I believe that sleep deprived people show a low performance in daily tasks due to suffering from mental, and physical health disorders.

There are distinctive stages of sleep REM sleep and non-REM sleep and about every ninety minutes we cycle through four recognizable sleep stages (Myers D 2014). Non-REM sleep consists for 3 different stages and during each stage it contains its own purpose. Stage one occurs for about 10 minutes and is when a person is lightly sleeping and can be woken up very easily (Mastin 2013). Muscles are still active and movement occurs more frequently such as twitches and the eyes roll around at a slow pace and breathing and heart rates slow down (Mastin 2013). Stage two happens between 45-50 percent of the night at different intervals (Mastin 2013). Muscle activity decreases and it is harder to wake up during this stage; if sounds are heard they are no longer able to make sense of them (Mastin 2013). The last stage: stage three which is also called delta

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.

There are studies that have shown that sleep and dreaming are linked to learning and to repair the body and mind. If we were to stop REM sleep or dreaming, the body recovers by increasing dream sleep first, recovering the loss of REM almost precisely. This suggests that dreaming is important. It has been observed that a lack of sleep causes waking dreams, interruption with memory and learning, difficulty of thinking straight, less associations, and more. It has therefore been suggested that REM or dream sleep is important in maintaining our well-being.

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

The first stage of sleep is the Non-REM Sleep. In this non-REM stage there are three sub stages that take place. The N1(R&K Stage 1) is the light stage or the beginning part of the sleep cycle. Sometimes in the light sleep people will experience a sharp “jerk” or “falling” feeling. If a person gets woken up during N1, they won’t believe they had been sleeping.

The beginning of the sleep cycle started with stage 1 which is considered a transition period between wakefulness and sleep.This period of sleep lasts for about 5-15 minutes.

Each stage of sleep has unique characteristics and the human body responds differently to each stage throughout the night. REM and NON-REM are important factors in the stages of sleep. REM stands for rapid eye movements. This means that behind closed eyelids, the eye is making quick, rapid movements. Only during the last and deepest stage of sleep do the eyes go through REM. During stage one our body is in the lightest level of sleep. This is the period of time where our mind is transferring from being fully awake to at rest. The human body starts to relax muscles, and tissues during this time. It is a period of NON-REM. Stage two is also NON-REM. Being quite similar to stage one, this stage is also the beginning of sleep. Brain activity becomes very minimal, while the body begins entering deep sleep. Stage three is the start of very deep sleep. A person's heart rate and breathing are at the lowest point they will reach throughout the night. The last stage of sleep is stage four. Stage four is the only period of time when the eyes are rapidly moving. This stage typically occurs two hours after falling asleep. Most dreaming occurs during this time, because of this legs and arms become temporarily paralyzed in order to prevent you from acting out dreams. Each stage of sleep is distinctive from the
