There are four primary stages of sleep in which human beings cycle in and out of (Pinel, 2007). The first stage is referred to as emergent sleep. During this phase EEG waves are both low voltage and high frequency. The second, third, and fourth stages are made of higher levels of EEG voltage and a decrease in frequency. The second stage of sleep mainly process two additional characteristics which are sleep spindles and K complexes (Pinel, 2007). Delta wave patterns can happen during the third stage of sleep. As the fourth stage of sleep occurs the delta waves become the most dominant pattern within an EEG (Pinel, 2007).…
Stage #4: brain produces Delta waves stage three and four are called deep sleep cycle. It is important to go through adequate sleep and get the sleep cycle run its course correctly. Our body repairs itself during sleep. Our body has an ingenious way of restoring our body as we sleep; during the day, there is a buildup of different chemicals including adenosine. All of these chemicals are what is thought to make us want to sleep. Scientists have discovered an immunity system in the brain that is called the lymphatic system. The glymphatic system is the main system that clears the waste product that build up in your brain.…
According to Krogh (2009), homeostasis is the maintenence of a relatively normal internal environment. This means that the body has many systems in place to regulate what happens in our bodies to keep it functioning properly. There are very few functions that we have control over in the homeostatic processes ' of our bodies. Sleep is one of them.…
Central sleep apnea is a disorder in which your breathing repeatedly stops and starts during sleep and contributes to heart failure which links your brain to your spinal cord and controls many functions such as heart rate. Nonetheless, there are certain factors which will more likely lead to increased risks among several individuals which are associated with central sleep apnea: especially among males who are more predispose to develop central sleep apnea than are females and Central sleep apnea is more common among older adults, especially adults older than age 65, possibly due to the fact that they may have other medical conditions or sleep patterns that are more likely to cause central sleep apnea. In addition people with atria fibrillation…
There are four stages of Non-REM sleep. In the first stage, you can be awakened without difficulty but it may leave the person feeling as if he or she has not slept. In the second stage, the body temperature and heart rate drop. At this point, your body gets ready to enter deep sleep. The last two stages are deep sleep stages, with the fourth being more intense. These stages are known as slow-wave, or delta, sleep. If woken up, you may feel disoriented for a while. REM sleep is described as sleep where rapid eye movement occurs. It is also known as “active sleep.” It is during REM sleep that we being to dream. On average a person can have 3 to 5 periods of REM sleep per night. REM sleep is characterized by a number of other features including rapid, low-voltage brain waves, irregular breathing and heart rate, and involuntary muscle movement. Sleep provides the human body with the energy it needs to keep on going. During the state of sleep, the body’s metabolic processes slow down and energy consumption is kept to a minimum. The human body requires rest to sustain its everyday activities, and hence sleep is…
Communication is an essential part of life and promotes self-expression and sharing of ideas. Communication is used to create to create motivation, planning and organizing, altering individual’s attitudes, and is a part of socialization. Everyone needs someone they can express themselves to that will listen, understand, and sympathize. Every voice and sol needs to be heard. While most people would agree having someone to talk to is essential in life, it is more important to have quality communication; not just talking for the sake of talking. Although George and Lennie’s relationship is an aspiring one, it lacks quality communication. George has to constantly remind Lennie of the things he has done or forgotten. Lennie’s lack of memory, inability to reply, and the overall incompetence the two have communicating, makes their relationship strenuous and aspiring. Lennie and George’s relationship provides each character a sense of security; As long as they are together, neither of them is alone in the world.…
Composes 20-25 % of a normal nights sleep. Breathing , heart rate and brain wave activity quicken. Vivid Dreams can occur. Sleep Specialists call this 5th stage of sleep "REM" rapid eye movement sleep because if one is to watch a person in this stage, their eyes are moving rapidly about. After REM stage, the body usually returns to stage 2 sleep.…
The third stage of the sleep cycle is when your brain has slow and deep brain waves called delta waves. During this stage people become less responsive and noises around them generally fail to generate any response from them.…
Stage 1: NREM -Stage lasts a few minutes. It includes lightest level of sleep. Decreased physiological activity begins with gradual fall in vital signs and metabolism. Sensory stimuli such as noise easily arouses person. Awakened, person feels as though daydreaming has occurred.…
Directions: Read the passage. Then answer questions about the passage below. “Wake up!” Do you hear these words often? If so, maybe you are not getting enough sleep. What is sleep? Why do people sleep? How much sleep do you need? All people sleep. All mammals and birds also sleep. Some reptiles, amphibians, and fish sleep too. Scientists understand some of the reasons for sleep. But they do not understand everything about it. There are two kinds of sleep in mammals and birds. One kind of sleep is Rapid Eye Movement sleep, which we call REM sleep. The other kind of sleep is Non–Rapid Eye Movement sleep, which we call NREM or non–REM sleep. The American Academy of Sleep Medicine divides NREM sleep into three stages: N1, N2, and N3 sleep. When people first go to sleep, they are in NREM sleep. The first stage of NREM sleep is N1 sleep. During N1 sleep, people get very drowsy. Some people have muscle twitches during this part of sleep. People are not very conscious of, or aware of, their surroundings during this stage of sleep. Brain monitors identify small, slow, and irregular brain waves during N1 sleep. The second stage of sleep is N2 sleep. People are not at all conscious of their surroundings during N2 sleep. About 45%-55% of total adult sleep is N2 sleep. Brain monitors identify large brain waves with quick bursts of activity during N2 sleep. The third stage of sleep is N3 sleep. It is very deep sleep. Brain monitors identify very slow brain waves during N3 sleep. Therefore, N3 sleep is called slow–wave sleep (SWS.) After N3 sleep, people cycle back to lighter N2 sleep before going into REM sleep. People cycle through the stages of NREM sleep 4 or 5 times each night and enter REM sleep several times during one night. Dreams occur during REM sleep and the eyes move quickly beneath closed eyelids. During REM sleep, people and animals are paralyzed. Scientists…

In a normal night of sleep, bouts of REM sleep lasting 5 to 30 minutes usually appear on the average every 90 minutes. When the person is extremely sleepy, each bout of REM sleep is short and may be very absent. As a person becomes more rested through the night, the durations of the REM bouts increase.…
