You have four stages: 1- Theta waves (high amplitude, slow waves) for 5-10 minutes, transition between awake and asleep 2- Sleep spindles for 20 minutes, body temp goes down and heart slows 3- Delta waves emerge (deep slow brain waves) this is the transition between light and heavy sleep 4- "Delta sleep", you're definitely having delta waves, you're in deep sleep and might sleepwalk, bed wet etc...30 minutes - REM...Rapid eye movement, increased breathing, and increased brain activity...here you'll dream you cycle through these five stages 4-5 times a night like this 1, 2, 3, 4, 3, 2 THEN REM (where you dream etc.), then back up and down. Common problems include sleep apnea (usually overweight males), sleepwalking, bedwetting, insomnia, chronic fatigue, restless leg syndrome, and narcolepsy Narcolepsy- daytime uncontrollable sleepiness, may fall asleep...caused by dysfunction of the brain mechanism that controls sleeping and waking Sleep apnea- disorder in which you’re breathing temporarily stops throughout the night. Can be caused by being overweight or any kind of blockage of the upper airways Sleepwalking - complex behavior accomplished while asleep, you can talk, even have your eyes open. Have a lot of causes like genetic predisposition or environmental causes like sleep deprivation or stress. Rapid eye movement is the stage in which we dream every night.
There are 5 stages of sleep. The first stage is a transition phase called Alpha Theta, eyes roll slightly, only lasts a few minutes. The 2nd stage called Theta Spindles is where brain waves peak higher and higher. The 3rd stage is called Delta Theta, and the brain waves move very slowly during this time. The 4th stage consists of 50% delta and theta brain waves and is the 2nd deepest sleep before REM sleep. This is called Delta theta. Beta is the 5th sleep stage and is the REM sleep. This is where the deepest…...

Sleep

...A Good Night’s Sleep- What is sleep? Sleep is defined as unconsciousness while are brain is still active processing and rejuvenating period. Sleep is a physical and mental resting period in which a person is unaware of their environment. In a normal sleep our body is changing by decreasing body temperature, blood pressure and other body functions. Sleep is very important to us and everyone for that matter because we all need to sleep and rest our bodies. It’s so important because it’s a vital biological function without sleep we know that our bodies are unable to function the way we want them to. We lose lack of day-time alertness, drowsiness and more susceptible to health problems such as stroke, diabetes, obesity and even depression. In the article ("Good night’s sleep") they discuss about College students sleeping patterns changing for example, not getting enough sleep. I felt that the article didn’t have information about sleeping patterns when there has been research about sleeping patterns. In 2002 Canadian Community health survey found that 18% of people sleep 5 hours or less a day. Sleep is put into two parts one being called non-REM and REM (Rapid Eye Movement). Non-REM consists of four stages of sleep, each deeper than the last. REM is when you are at the most active sleeping you are dreaming and your eyes are moving rapidly. Our sleep patterns consist of stages 1-4. Stage one last about 5 minutes, easily awaken. Stage 2 first stage of sleep about first 25......

Sleep

...definition of terms. Background of the Study Sleep is an integrated part of human health and life and is crucial for learning, performance, and physical and mental health. Sleep deprivation is a serious problem facing individuals in many critical societal roles. It is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function. Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. Complete absence of sleep over long periods is impossible for humans to achieve (unless they suffer from fatal familial insomnia); brief micro sleeps cannot be avoided. A National Sleep Foundation survey found that college/university-aged students get an average of 6.7 hours of sleep each night. Sleep deprivation is common in first year college students as they adjust to the stress and social activities of college life. A study performed by the Department of Psychology at the National Chung Cheng University in Taiwan concluded that freshmen received the shortest amount of sleep during the week. In 1997 the University of Minnesota did research that compared students who went to school at 7:15 am and those who went to school at 8:40 am. They found that students who went to school at 8:40 got higher grades and more sleep on weekday nights. One in four U.S.......

Unit 4 Predictable and Unpredictable Life Stages

...Predictable 1. Starting school or nursery Which Lifestage? Positive: This is a big life stage for young children as it enables them to have distance from their parents, and become slightly more independent. It enables them to socialise with other children and learn new things, it also gets them into a routine. Negative: It can be very daunting for the child and the parents, it can also be very traumatising especially if the child has attachment issues. P Physically they will learn to cope on their own, they will learn how to do simple things like take off their coat and put it back on again. They will also begin to learn about writing, and how to write or draw. I Intellectually the child will be challenging their brain, as they will be learning about new things all the time, such as using new materials they have never seen, or writing and drawing. E Emotionally they may feel overwhelmed. They may feel very distressed when they first start going to nursery because it is perhaps being away from somebody familiar for the longest period of time they have experienced. S Socially, they will be meeting new children their age and having to socialise with them on a regular basis. They will learn about different people. Parents will also have a chance to mix with other parents with children of similar ages. Predictable 2. Which......

...occurs. Sleep is truly a wondrous process. During sleep, our brain takes our bodies through five different stages: rapid eye movement and non-rapid eye movement, otherwise known as NREM, which represent four of the five stages. Each stage corresponds differently in length and produces different brain waves as well as dreams. The first stage of sleep is very brief and the sleeper experiences hypnogogic sensations. Stage two is a deep, twenty-minute cycle, and the third is short in length, much like the first. However, it is also the transitional period into stage four, which lasts thirty minutes long. REM sleep ends the course of the sleep cycle, lasting a total of ten minutes or more. Sleep begins in stage one and progresses into stages two, three, and four. After stage four, stage three and then stage two are repeated before entering REM sleep. The total time it takes for a person’s body to go through all five stages is about 90 minutes. Stage one is a very light sleep. The person is not technically asleep yet, for he/she is easily awakened. During this stage, many people may experience hallucinations that are mistaken for dreams and/or falling/floating sensations. David Meyers defines hallucinations as, “[f]alse sensory experiences, such as seeing something in the absence of an external visual stimulus.” (p.94) Many people will recall being pinned to their bed or floating, when in reality it was the normal occurrences of the first stage of sleep. During this......

Sleep and Sleep Disorder in Early Childhood

...There is much to be learned about the ins and outs of sleep such as how much it provides for the body and the brain and how to best manage a person’s ability to “sleep well”. Examining sleep from a parent’s perspective is something I never thought about before. However, I know first-hand how proper sleep, and lack of proper sleep may affect children’s behavior. I clearly recall being in the hospital when my oldest was only a day old, walking the floors trying to soothe him to sleep. Even now, at four, he still wakes in the middle of the night and comes down the hall to my room. My two-year old daughter is better with her sleep. However, she began climbing out of her crib just after turning two and we made the move to a toddler bed shortly after. It is quite a challenge for her to fall asleep; when she does, she does not stay in her room and wakes up during the night. It occurs to me that my son has never learned to become a good sleeper and it has affected many areas of his life. He is often tired but refuses to sleep; he is cranky and quick to show emotions in extremes with very large tantrums. These symptoms are more contained and less noticeable when he sleeps through the night and/or goes to sleep at a reasonable time. Similarly, my daughter refuses to sleep and misses naps, or has shortened them considerably when she does nap. We observed that after a night of multiple waking, and/or short or missed naps, she will have what we have learned are possibly Night......

Sleep Stages

...Stage 1 This is the beginning of the sleep cycle and is a relatively light stage. This is more of a transition period between wakefulness and sleep. In Stage 1, the brain produces high amplitude theta waves, which are very slow brain waves. This period of sleep lasts only a brief time (around 5-10 minutes). Stage 2 This stage lasts for approximately 20 minutes. The brain will begin to produce bursts of rapid, rhythmic brain wave activity known as sleep spindles. Your body temperature starts to decrease and heart rate begins to slow. Stage 3 This is deep, slow brain waves known as delta waves begin to emerge during stage 3 sleep. Stage 3 is a transitional period between light sleep and a very deep sleep. Stage 4 At this stage, sometimes referred to as delta sleep because of the slow brain waves. This is a deep sleep that last for approximately 30 mins. Dreaming A majority of the dreaming occurs during the stage referred to as REM, or the rapid eye movement stage. This is characterized by eye movement, in which the eyes dart back and forth under the eye lids. Dreaming occurs during this stage because of increased brain activity, voluntary muscles become paralyzed. There are five common beliefs about dreaming. They are: External stimuli are incorporated in to our dreams. Dreams last only an instant. They do not dream. Penile erections indicate sexual content of dreams. Sleep talking/walking can occur. Two common theories that have been......

Stages of Sleep

...Five Making Six Stages of Slumbering Activities in Your Brain By: Bill Pak Section: #1762 (I was allowed permission by you to turn in this term paper due to some personal issues with the original term topic) Ever wondered what in blue blazes your brain is doing when you sleep? Well so far, all the research and experiments that have been made to understand and answer this question have resulted with the so called six stages of sleep. The six stages of sleep starts from Stage 0 to Stage 5. Stage 0 is not really considered a stage since it involves the person of interest being awake. Sequentially, Stage 1 is considered to be the beginning of being asleep. Following Stage 1 is Stage 2 which is well known for its sleep spindles and K-complexes (L & F 8). Afterwards, Stage 3 is considered to be a transition phase towards Stage 4 and both stages are collectively often titled as deep sleep (McPhee 20). Lastly, but not the least, Stage 5 is identified as dream sleep and with REM (McPhee). Each stage is not just discerned by its major aspects, but by the activity in the brain in each stage. Although sleep can be described through the various behavioral changes, the different activities in the brain allow the discerning of each stage during sleep. Each stage is distinguished by various electrical activities and patterns across the brain (L & F 7). These electrical activities and patterns consistently change between each stage (McPhee 17). Obviously, each stage has its own......

Sleep

...1 Sleep Deprivation, Disorders, and Drugs Amanda Powell Psychology 240 3/14/14 Jennifer Graves 2 There is one distinctive time that I remember not having enough sleep and feeling deprived of it. I was up all night with my new puppy, this was just recent actually. She was sick all night, and I had to get up and go to a job interview in the morning, only being able to sleep for about 3 hours when I woke up I felt, as they say “groggy”, I was more tired when waking up than I had been going to sleep if that make sense. As the day went by I could feel the change in my mood, because I would snap very easy at things that were not pleasant. I felt emotionally drained and I was not my normal self, or how I would usually feel if I had gotten enough sleep the night before. My behavior felt as if I was trying to rush through things just to be able to get it done, because I had not had the motivation to do it, being so tired. Luckily when I went to the interview it was short, because they most likely could have told that I was sleepy. In the end I got the job, but I had felt very unmotivated and snappy all day. I think that sleep is important for one’s energy the next day. In my experience I believe that it is related to the effects that our book describes. I felt not myself in any sort, and I felt sleepier. That night I had fallen asleep very vast just as the text has described when a person is deprived of sleep. As well it may be just as described in the text that I was......

Unit 4 Development Through the Life Stages D1

...For this part of the assignment I am going to be evaluating how nature and nurture may affect the development of an individual over two life stages. I will be looking at the effects of nature, nurture in relation to the Jim twins, development over their childhood and adulthood. D1 Nature and Nurture Effects on Childhood Physical Development The Jim twins were identical twins and nature obviously had a big effect on how they looked, both the boys inherited genetics from their parents which determined what they were going too looked like, during their childhood the boys would have looked identical, but they just didn’t know each other. But one twin in his childhood had a fringe and the other didn’t, these different hair styles would have been the effect of nurture as he would have been influenced to have his hair that way by seeing others with the same hairstyle or his adoptive parents wanting him to have his hair like that. Nature would have had an effect on the twin’s physical development as the genes they gathered from their biological parents would have determined that during their childhood, they disliked basketball and other sports, this could have been because, both their parents may not of been very sporty, which could of led them to inherit gene which meant they were going to be very athletic/sporty either.

Sleep

...Sleep 2015 Gabe Wai Sleep  is something that we can always have enough of, for our body to function fine with plenty of energy because our muscle repair, memory consolidation and release of hormones regulating growth and appetite have completed their phase in the body. 117 When you start drifting off your heart rate and breathing slows down. 1 Most children 6- 13 need to sleep from nine to eleven hours each night. a baby needs to obtain around 16 hours of sleep a day but it can be spread out over the course of one day.1 In a day a newborn will sleep throughout the day and will not sleep all the way through the night till about 1 year old because they don't need as much of feeding and are doing more in the day. 1 As people reach 14, they start needing less and less sleep until they are older than 65. 1 Most 26 - 64 need seven or nine hours of sleep. 1               When studying sleep doctors use several different machines but one way is using the EEG, which stands for Electroencephalography and measures Brainwaves on a graph. We have 5 different waves our body goes through at night.20 We have alpha/beta, theta, delta, and REM. 25Alpha and Beta are high frequency and low amplitude.25 Theta is high amplitude and low frequency.25 Delta is high frequency and very low amplitude.25 REM is high frequency and low amplitude.25 The way scientists know our body is sleeping is, they use a machine that uses the body's’ electrical waves given by the brain using polysomnography(......

Stages of Sleep

...There are five stages of sleep. They are 1. Falling asleep and trying to get comfortable. Some people can get through this stage in a few minutes and other people it takes longer. 2. You go into a light sleep. You can still be taken up easily here but you are starting to lose consciousness. Your heart rate and breathing slow down here. 3. You are in a deeper sleep and on to the 4th stage of deep sleep. This is also called delta sleep because of the delta waves of the brain. This is when your body relaxes and regenerates. The final stage is REM or rapid eye movement. In this stage you dream. There are some beliefs about dreaming which are: External stimuli such as a phone ringing or knocking on the door can intergrade into your dreams. Another belief is that dreams last a short time. Some also feel that they do not dream at all while others believe that erections are due to a sexual dream when they are actually due to sheets or something rubbing against the penis. Sleep walking and talking are a belief that happen while you dream. A couple of theories of dreaming are recuperation where your body restores itself and psychoanalytic dreams where your subconscious acting out your hidden desires or thoughts accord to Sigmund Freud. There are other theories about dreaming as well such as we dream as therapy to make sense of things. I think we dream for all of the reasons. I think that for me anyway, it helps me deal with things and realize things to make sense......
