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.
Their sleep was also restricted on the night before the laboratory day. Research found that there was not enough evidence to support that caffeine intake improved the way young adults felt or acted during the testing period, contrary to the world wide conception that caffeine is a effective stimulant. The testing was done 4 times and took about 2 hours to complete. Sleep is also a very important factor when it comes to performance and mood, whether or not caffeine is ingested. The Effects of Sleep and Caffeine on Performance and Mood The study was done to see if performance and mood could be affected in healthy young adults by their daily caffeine intake and sleeping habits.
Daydreaming happens more often than some. If daydreams are recognized and interpretation of a dreams happen just the slightest bit, it is possible to take advantage of the dream world and control it. Imagine feeling a constant drag every single day believe it or not people do feel like that every day because of a sleep disorder called insomnia. In an online article Andrew Weil, M.D explained “Insomnia is a relatively common sleep disorder, affecting about one third of the adult population worldwide.” (2011) In addition to not being able to sleep at night, insomnia will also cause drowsy effects and frequent falling asleep during the day. This will have a drastic affect if working is the activity or something that requires full attention.
Sleep and psychology are very closely related in that psychology studies mental processes and behavior, while sleep effects the wellness and health of those mental processes and behavior. These studies will present the facts needed to properly understand the negative effect poor amounts of sleep can cause on cognition, as well as the relationship between cognitive training and sleep quality. Sleep-Deprivation “The National Sleep Foundation (2005) reported that even among the general population, 75% of adults regularly experience at least one symptom of sleep disturbance a few nights a week” (Peachey, Zelman, 2012, p.18). Because sleep disturbance can lead to such a wide array of medical
Conclusions: 1. A large majority (73%) of the students indicated at least occasional sleep problems, with women reporting more of some difficulties than men did. 2. College students suffer a decreased level of sleep quality compared with a normal adult population 3. Environmental and other demands during college years contribute to students sleep difficulties; students stress and demands may interfere with sleep habits.
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.
The act of dreaming is the experience of situations, images, emotions and thoughts that take place during sleep. Dreams are strongly associated with rapid eye movement also known as REM sleep, during which an electroencephalogram shows brain activity to be most like wakefulness. The contents and biological purposes of dreams are not fully understood, though they have been a topic of speculation and interest throughout recorded history. The notion that dreams have a deep meaning behind them was greatly favoured by Psychiatrist Sigmund Freud who believed the interpretation of dreams were sources of insight into unconscious desires. Another Psychiatrist, Carl Jung, also believed that dreams held significant meaning.
Equally, REM is also important in the functions of sleep. This is shown through new-born babies spending 8 hours of their day REM sleep which is higher than any other age group in humans; i.e. babies have around 4 hours a day in REM whereas adults have around 2 hours a day. This is due to humans being born ‘immature’ (not born with neurotransmitter connections in brain) thus requiring rapid brain growth. Animals that are born mature, like dolphins never sleep in REM because they don’t need this brain growth, illustrating a link between neural development and restoration and REM sleep.
Sleep has been found to be more important in children than adults. A study was taken on 12 year old children to see what effect sleep had on them. In this study, there was a comparison between overweight children that slept only 14.4 minutes less than normal weight children (Horne). The results brought the conclusion that for every extra hour of sleep, the child was 20%-40% less likely to be overweight (Horne). This appears to be a bigger impact than in adults.
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.
