Informative Speech On Rem Sleep

All mammals exhibit Rapid-Eye-Movement, or REM, sleep, and yet on certain levels this type of sleep would seem to be disadvantageous. During REM sleep, which is when most dreams occur, the brain uses much more energy than during non-REM (NREM) sleep. (1) This "waste" of energy coupled with the increased vulnerability of this state on account of the body's paralysis at this time suggests that there must be a very important reason, or reasons, for the existence of REM sleep and in extension of dreams. Determining the function of dreams, however, has proved very problematic with many arguments which directly oppose each other. Some of the primary functions of dreaming have been

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.

Specific Purpose: At the end of my speech, the audience will understand what insomnia is, what

Sleep apnea is a condition in which breathing pauses or becomes shallow during sleep. Sleep apnea screening is a test to determine if you are at risk for sleep apnea. The test is easy and only takes a few minutes. Your health care provider may ask you to have this test in preparation for surgery or as part of a physical exam.

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

Purpose: To inform the audience about what sleep is and how it helps the body.

Specific Purpose: To inform the audience about the long term effects of lack of sleep

Thesis/Central Idea: Sleep deprivation can lead to serious health problems, forgetting important information, and will have a negative impact on the outlook of life.

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

As work hours become longer and people’s lives become more packed, the number of hours of sleep that people are privileged to, also shortens. This leads many to question the importance and meaning of sleep. Grivas, Down, and Carter (1999) defines sleep as a “regularly occurring altered state of consciousness that occurs spontaneously and is characterized by a loss of conscious awareness.” There are four to five sleep cycles per night which consists of a period of non-rapid eye movement (NREM) and rapid eye movement (REM). Non-rapid eye movement is when the body recovers, the neurotransmitters are replenished, and the body tissues are repaired. Rapid eye movement sleep is necessary for the restoration of mental functions. This is known as the repair and restoration theory of sleep. Recent research also points to a variety of other different theories, most notably, the evolutionary theory. The evolutionary or adaptive theory suggests that sleep has evolved to protect animals from danger. In this review, the strengths and limitations of the two theories of sleep will be analysed and evaluated.

This stage is believed to help people enter deeper stages of sleep (4). Stage 3 sleep consists of 20-50 percent delta activity and stage 4 sleep of more than 50 percents delta activity (4). Stages 3 and 4 are characterized as being slow wave sleep in addition to being the deepest levels of sleep. Approximately 90 minutes after being asleep, people enter rapid-eye-movement (REM) sleep (4). REM sleep consists of rapid eye movements, a desynchronized EEG, sensitivity to external stimulation, muscle paralysis and dreaming (4).

Title of Speech: The Importance of Sleep and the Effects It Can Have on Our Bodies

 REM Sleep (Rapid Eye-Movement Sleep): a stage of sleep associated with dreaming, and characterized by frequent eye movements, suppression of the muscles.

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).

1. Your body goes through 4 stages of sleep. REM (rapid eye movement) is the 4th stage and when you do most of your dreaming. “While you are dreaming, your body undergoes noticeable changes.  Your adrenaline rises, your blood pressure increases, and you heart beats faster. Given this hyperactivity, it should be no surprise how someone with a weak heart can die in their sleep (dreammoods.com).” It usually takes 30-90 minutes to reach REM, a person goes in and out of REM 4-7 times a night. During REM your eyes rapidly move back and forth under the eyelids. Our bodies are completely immobile and muscles are relaxed. You may shift around in your sleep but when in REM you are completely still.
