Before adolescence, these circadian rhythms direct most children to naturally fall asleep around 8 or 9 p.m. But puberty changes a teen's internal clock, delaying the time he or she starts feeling sleepy — often until 11 p.m. or later. Staying up late to study or socialize can disrupt a teen's internal clock even more. Too little sleep Most teens need about nine hours of sleep a night — and sometimes more — to maintain optimal daytime alertness. But few teens actually get that much sleep regularly, thanks to factors such as part-time jobs, early-morning classes, homework, extracurricular activities, social demands, and use of computers and other electronic gadgets.
It is suggested that Teens get a healthy 8.5 - 9 hours of sleep a night as compared with eight hours needed for adults.. However Only 15 percent of teens get this required amount of shut eye. Teens also tend to have irregular sleep patterns across the week, they typically stay up late and sleep in late on the weekends, which can affect their biological clocks and hurt the quality of their sleep. A recent survey taken of 3,000 students at Providence high school showed that 85 percent of the students were not alert at the start of class because they weren’t getting enough sleep ("Are Teens Getting Enough Sleep?"). Sleep is essential for learning and memory.
As childhood progresses, the need for sleep decreases, but in adolescence it increases slightly, to around 9 or 10 hours a night. Circadian rhythms are also known to change which cause teenagers to feel naturally more awake later at night and have more difficulty getting up early (phase delay). A distinguishing feature of adolescent REM sleep is that in males it is sometimes accompanied by orgasm or ejaculation, which is significantly less likely at other ages.
It has been suggested that babies sleep longer as an adaptive measure to make their parents life a lot easier. This is shown as adults are then able to clean, sleep and eat to ensure better survival. This is supported by the fact that premature babies whose brains are very underdeveloped spend about ninety percent in REM. A one year old will now have established a gradual maturation of sleep EEG patterns thus they begin to look more like adults. They are usually able to sleep at night and therefore have fewer naps during the day totalling about 10-12 hours of sleep a day.
Rather, they focus on alcohol abuse and what they see as larger issues. It has been proven that both the quantity and quality of sleep are associated with a college student’s mental health and academic achievement. Total sleep deprivation can also cause problems with athletics, time management, and self-regulation. Studies have found that approximately twenty percent of college students suffer from sleeping disorders like insomnia, which cause sleep deprivation, along with experiencing irritability, anxiety, and even weight gain (sleepdeprivation.com). Although many students claim they can manage with only a few hours of sleep, it has been proven that there are many detrimental effects of missing out on something many overlook as a minor daily activity.

Describe and evaluate lifespan changes in sleep? (24 marks) As humans grow from infancy to old age there are major changes in the amount and kind of sleep experienced. Babies tend to sleep a lot more than adults roughly around 16 hours a day. They usually wake up every hour or so their sleep cycle is not 90 minutes. Infants have sleep stages similar to adults called quiet and active sleep; these are immature versions of SWS and REM sleep.
If one is sleeping too little every day, the body will collect all the sleeping time owed to the brain and will build up quickly causing tiredness and low energy. This leads to fatigue and a reduced ability to focus and concentrate on the tasks at hand. It is said that humans should get approximately eight hours of sleep per night. For example, imagine getting roughly four hours of sleep each night of the week instead of the recommended eight because going to bed is not as enjoyable as staying up with your friends. By the end of the week, a total of twenty-eight hours of sleep has been lost!
Obesity is caused by many factors, one of these consequences is one that people often overlook, poor sleeping habits. The quality and duration of sleep amongst modern society has decreased in the last fifty years. According to self-reported sleep durations presented in a study titled “The Impact of Sleep Deprivation on Hormones and Metabolism,” people have gone from sleeping 8.0-8.9 hours a night in 1960 to, on average, only being in bed 5-6 hours in present day(Van Cauter et al). But why has sleep duration decreased? With technology advancing and becoming ever present in people’s lives, it has therefor become much easier to fill waking hours with as much as possible.
Moreover, children who are heavy viewers are among the lowest achievers at school because they do not develop imaginative skills to create fictitious characters, situations and make-believe worlds. In short, excessive television watching hours may plague the healthy thinking of children. Besides, most television broadcasters show a variety of programs 24 hours a day, giving the viewers a 24-hour service. More time spent watching these shows is linked with poorer overall school performance and lower grades on standardized
