Outline lifespan changes in sleep It has been found that over a lifespan there are decreases in total sleep time, deep sleep and REM sleep. Also, there are increases in sleep latency (time taken to nod off) and stages 1 & 2 sleep time. Van Cauter et al (2000) carried out a longitudinal sleep study on male participants. Of particular interest was their finding: DEEP SLEEP DETERIORATES IN 2 STAGES. Between 16 and 35 years and between 35 and 50 years During infancy babies sleep more than everyone else and have different sleep patterns.
It also causes the reaction time to slow down, sometimes behavior becomes unpredictable, ability to make decisions decline. People do not always know when they are not getting enough sleep and when you are deprived of sleep, you are craving sleep. My results from the sleep deprivation test were 11 points and I could not trace the star accurately with my nondominant hand. I also realized that I fall asleep after a lot of activities such as; watching TV, in class during lectures, eating heavy meals, within five minutes of me getting into bed. It’s also hard for me to wake up in the morning without an alarm clock, I struggle to get out of bed, and I hit my snooze button a lot of times.
Surveys show that teens rely on naps to make them more refreshed. You should only take at the maximum a 45 minute nap anything more than that disrupts your biological clock and this is what causes you to wake up angry or irritable from a nap. Other factors also play a role in getting good night’s sleep. For example, caffeine plays a huge part in not getting any sleep, 31% of adolescents surveyed said that they cannot sleep after drinking a caffeine drink before bed. Technology also has a huge role in not getting to sleep.
Discuss lifespan changes in sleep (24marks) By Rebecca Cox Sleep is a naturally recurring state characterized by reduced or absent consciousness. The sleep –wake cycle is an example of a circadian rhythm, as we have one main phase of sleeping and waking with takes place over twenty four hours. However within the time that we are asleep there is another cycle; the sleep cycle itself. This is known as an ultradian rhythm since on complete turn of the cycle from slow wave sleep one to the end of REM takes less than twenty for hours. As new born babies grow to adults there are major changes in the amount of sleep and kind of sleep that a human experiences.
However stuffing information into your brain takes time, which is taken up by being in school and other activities. By staying up late studying, we compensate for those lost hours and get a leg up on the students who didn’t stay up. Or so we think… In a study done by Pilcher and Walters, 44 college students were placed into either a sleep deprived, or non-sleep deprived group and allowed to sleep and wake up at certain time during the three-day experiment. After the three days were up, each group took a series of tests and questionnaires. When asked how they thought they did, the sleep deprived group reported to have had a higher level of concentration and an increased level of effort.
Trinh Le Larry Bounds AP Language and Composition 26 August 2014 Amount of Sleep Required Everybody goes through a 24-hour cycle for each and every day. Within those 24 hours people can choose to be lazy, active, productive, adventurous, studious, or even curious. No matter what the answer is, one thing we all have in common is that we all need sleep. Sleep is a condition when our body and mind recurs for many hours every night, in which the body system is inactive and relaxed. Therefore, after a long day of doing nothing or work, the human body has to be fatigued and needs rest or even better the body and mind needs sleep.
By the age of 6 months a circadian rhythm is established and by the age of 1 year infants are usually sleeping mainly at night, with 1 or 2 naps during the day. The periods of deep sleep lengthen and there is a reduction in the amounts of active/REM sleep. Sleep patterns change during childhood and by the age of 5, children have EEG patterns that look like those of an adult but they are still sleeping more (around 12 hours a day) and having more REM activity (about 30% of total sleep time). Boys are also found to sleep slightly more than girls. As childhood progresses, the need for sleep decreases, but in adolescence it increases slightly, to around 9 or 10 hours a night.
Reduced sleep can add manic and hypomania episodes. Studies have found that 25% to 65% of bipolar patients who had a manic episode have experienced social rhythm disruption prior to the episode [ (AstraZeneca, 2009) ]. Social rhythm disruption can throw off a person’s sleeping cycle. This can be as simple as staying up late working, watching television or even being nervous about something and not being able to sleep. Once a person lacking sleep has gone into mania they start believing that they do not need sleep and will stay awake for more than 20 hours, this makes the disorder worse [ (AstraZeneca, 2009) ].
Many of us also think that sleep is a passive, constant and unchanging process. Yet, what we don’t realize that sleep is in fact a very active state. Our bodies move frequently during the night, but what’s even more striking is that our brain activity is more varied than it is when we are awake. As we sleep our body goes through what is called a non-Rem and Rem sleep. (REM stands for the Rapid Eye Movement) Typically we begin our sleep cycle with a period of non-REM sleep, what is than followed by a very short period of REM sleep.
I was able to spend the rest of the day doing homework, hanging out with friends, etc. But on some days, I don’t feel like going to class because I stayed up late the night before. But I am a morning person and I usually get up a 5 pm to run in the morning so starting English class at 8 A.M wasn’t very difficult for me. Being in a class at 8 in the morning affected my performance. On some days where I don’t get enough sleep, I don’t pay attention to what the professor say and I don’t do as good as I should when I’m fully alert.
