Fifth Stage REM 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.

Then you will move into stage two which includes sleep spindles and K complexes. Sleep spindles are very short bursts of brain activity, and K complexes are single high voltage strikes of brain activity. Also, in stage two delta brain waves start to slow function of the brain preparing for stage three and four. Stage three and stage four i will talk about as one because they are very similar and do similar things. These stages are referred to slow wave sleep because your brain is in it’s slowest speed of function. In stage three you brain is between 20 and 50 percent delta waves, from 50 to 100 percent delta waves you are considered to be in stage four. While in stage four people may experience sleep walking and other muscular movement without knowing so. Noises as loud as 90 decibels may not be able to wake the person from sleep. During REM sleep which is after NREM sleep the brain is more active and alert. This is where most dreams occur because your brain is active but you are still sleeping. After the short 15 minute period of REM sleep you will start over with stage one of NREM these cycles normally take 90 minutes to complete. Activity during sleep can come at any point but is most common in REM or stage four of

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.

A person will spend 50 percent of their full cycle in this stage. NREM stage three is next, this is the stage when all your muscles start relaxing blood pressure drops and the deepest sleep happens. While in the stage people are not as responsive to sounds and are more difficult to be woken up compared to stage one. This is also a transition from light sleeping to ideal deep sleep. After that stage the last stage is REM sleep, in this stage most of your dreaming happens, you spend almost 20 percent of a your full cycle in this stage. The brain is more effective, and cir body is relaxed. Since the brain activity is so active in this stage that is why dreams are developed also because your muscles and body is relaxed. Throughout the cycle it does not go in that order it goes through all three stages multiple times before entering REM sleep. You will go through all stages about four or five times every night. Also theses stages will also start off short but will increase in time the longer

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.

NREM stage one is the beginning of the sleep cycle. It is known as the transitional stage between being awake and being asleep. During this stage, your brain produces theta waves, theta waves are extremely slow brain waves. This lasts about 5-10 minutes. NREM stage 2 of sleep lasts about 20 minutes. During this stage, the brain produces sleep spindles which are bursts of rapid and rhythmic brain wave activity. This is when everything starts too slows down. NREM stage 3 is when your brain produces delta waves during this stage which are very slow and deep brain waves. This stage lasts about 35-45 minutes. REM sleep is most dreaming occurs during this stage. This stage has rapid eye movement, increased respiration rate, and increased brain activity.

REM sleep stands for rapid eye movement sleep. Most adults only spend 20% of their time sleeping, in REM sleep. This accounts to about 90-120 minutes each night. Babies spend about 50% of their total time sleeping in REM sleep. While babies are in REM sleep, they are actually not dreaming like adults do during REM sleep. Babies are actually forming connections between neurons and much of the growth and development of the brain takes place while the babies are in REM sleep. REM sleep usually occurs during the middle to the end of the sleep cycle, especially the hours before waking up. During REM sleep, your eyes start moving from side to side, hence the name, rapid eye movement. During the night, people will experience REM sleep four or five times. The first cycle does not last very long, but

Science has shown us that when we sleep there are five sleep stages. These stages move from light sleep to deep sleep and finally ending in REM (rapid eye movement) sleep. REM sleep periods occur approximately every sixty to ninety minuets through out the night. This is where the dreams are the most vivid and most often remembered. The REM sleep stage is characterized by rapid eye movement, increase heart rate and breathing, and elevated blood pressure. In an eight hour night there may be four to six dream periods, which is surprising since you often cannot remember even one

Rapid eye movement sleep or REM sleep is a stage of the natural sleep cycle occurring in Humans. According to Nairne (2014), REM sleep is paradoxical since the brain’s electrical activity appears as if awake with extremely active activity taking place as interpreted by an EEG. As the name indicates while in the stage of REM sleep the eyes move rapidly from left to right, up and down while the rest of the body is extremely relaxed. When the body does not achieve REM sleep be it intentional for research or unintentional possibly due to a sleep disorder, it can lead to REM rebound according to Nairne (2014). REM rebound is a tendency which the body attempts

Our sleep cycle is usually five ninety-minute long cycles and consists of four stages of NREM sleep and is followed by REM sleep. Constant disturbances with the sleep cycle may result in sleep deprivation. After being sleep deprived, people tend to develop microsleeps which are episodes of sleep lasting only a few seconds that occur during wakefulness. People who are sleep deprived experience disruptions in mood, mental abilities, reaction time, perceptual skills, and complex motor skills and tend to consume more calories and gain weight. When sleep becomes uninterrupted after being sleep deprived, the person will experience REM rebound. REM rebound is the amount of time spent in REM sleep increases by as much as fifty percent. The brain needs to experience the full range of sleep states, making up for missing sleep components when given the

Non-REM sleep is a much deeper, more restful kind of sleep. In non-REM sleep, the person’s body is free to move around. Non-REM dreams are more likely to consist of brief, fragmentary impressions that are less emotional and less likely to involve visual images than REM sleep dreams and are more frequently forgotten. The period of Non-REM sleep is made up of four stages. Each stage can last from 5 to 15 minutes. A completed cycle of sleep consists of a progression from stages 1-4 before REM sleep is attained, then the cycle starts over again. People begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep (Chang, 2010).

The REM stage may be ten minutes or an hour long, and breathing is shallow, eyes moving rapidly, muscles are relaxed and dreams vivid.

Using an electroencephalogram, researchers noted four distinct stages of NREM sleep and one stage of REM sleep. As we sleep, we cycle through these stages like a circuit at the gym; spending more time on some machines and less time on others. We spend as much as ninety minutes in NREM stages and as little as ten minutes in REM per circuit.

During this stage, many people experience sudden muscle contractions preceded by a sensation of falling. In stage 2, eye movement stops and brain waves become slower with only an occasional burst of rapid brain waves. When a person enters stage 3, extremely slow brain waves called delta waves are interspersed with smaller, faster waves. In stage 4, the brain produces delta waves almost exclusively. Stages 3 and 4 are referred to as deep sleep or delta sleep, and it is very difficult to wake someone from them. In deep sleep, there is no eye movement or muscle activity. This is when some children experience bedwetting, sleepwalking or night terrors. Usually, REM sleep occurs 70-90 minutes after someone has fall asleep. The first period of REM typically lasts 10 minutes. Each REM stage gets longer, and the final one may last up to an hour. A sleeping individual's heart rate and breathing quickens. People experience more intense dreams during REM sleep, since the brain is more active. Dreams are constantly occurring throughout the sleep cycle so do not believe anyone who says they do not dream.

Non-REM stands for non-rapid eye movement. NREM sleep has four stages. Each stage can last from five minutes to fifteen minutes. Stage one consists of alpha waves. Alpha waves are the normal electrical activity when the brain is unconscious or relaxed. In stage one, a person can be woken easily, and if they do get woken up, it would make the person feel as if they hadn’t slept. Also in this stage, you often get a falling sensation and suddenly jerk awake, this is caused by a sudden muscle contraction. This muscle contraction is called the “Hypnagogic Jerk.” This is one of two sleep paralysis. In stage two, your muscles continuously relax and then tense up. Your heart rate slows
