The sleep patterns amongst students aged 13-19 on the weekdays and weekends.

The investigation was base on the variation in sleeping patterns of students aged 13-19 years of age on weekdays and weekends. This was a non-experimental design in a form of a survey. 69 Males and 81 females a total of 150 student’s where used for this survey. The survey used means such as second person survey, the Internet and social net working. The 150 people surveyed where of convince as they where all students. The results indicated that the student’s surveyed where getting less than the recommended hours of sleep (8 -9 hours) on weekdays and the recommend hours of sleep on weekends, it was also overwhelming in the results that on weekdays the wake up time was not preferred. The reasons for these results could be biological, environmental, social & cultural. This survey cannot be generalized because it is not a general representation it is a sample of convince.

The research investigation aims to find out the sleeping patterns or sleep wake cycle (the species-specific biological pattern of alternating sleep and wakefulness, in humans) of students between the ages of 13-19. Specifically this task aims to investigate the number of hours the students sleep on weekdays compared to weekends and if the participants wake up on the preferred time on school days. It was hypothesised that teenagers (13-19 years old) are achieving less than the recommended hours of sleep (8 -9 hours) on weekends. In addition the time that they wake up on a school morning is not there preferred time. The hypothesis was supported by previous research such as research done by DR Karl S. Kruszelnicki 3 May 2007. In this research DR Kruszelnicki states that the natural circadian rhythm (A circadian rhythm is any biological process which displays oscillation of about 24 hours, they are adjusted to the local environment by external cues called zeitgebers, commonly the most important of which is daylight.) is interfered with in the adolescent years (13-19) because there is a decreasing delay of onset sleep, probably due to the later realize of melatonin (a light sensitive hormone that makes us feel tired when it is dark). Kruszelnicki also states that adolescence need more sleep than adults and children. Kruszelnicki explains that for many teens it is biologically impossible to get to sleep early and that because of this various studies have shown that average high school students are sleep- waking also known as somnambulism( a sleep disorder. Sleepwalkers arise from the slow wave sleep stage in a state of low consciousness and perform activities that are usually performed during a state of full consciousness.) Through there school days in a semi-permanent state of sleep deprivation (the condition of not having enough sleep). Various studies have shown that sleep deprivation can have nasty side effects in teens such as rebellious behavior, depressive symptoms, cigarette smoking, obesity, anxiety disorders and poor school marks. In the group this hypothesis was partly supported as on weekdays the participants got on average7.75 which is less than the recommended hours sleep however in weekends the participants got on average 9.175 hours sleep being more than the recommended hours sleep. While the individual results where very similar to the group results being that the participants reported to be receiving on average 7.8 hours sleep which is less than the recommend hours. However the individual results where supported by the hypothesis in the fact that the participants reported to receive on average 8.5 hours sleep, just on the recommended hours sleep. The independent variable of this research was the hours of sleep the students received and the dependent variable was the days of the week if it was a weekday or a weekend. This research was necessary to gain knowledge in to the sleep wake patters of students and the reason that could contribute to these sleeping...
