The Effect of Sleep on Academic Performance and Satisfaction with Life among University Students
Today, it is not uncommon to hear people complaining about not getting enough sleep. Most of us have probably heard the saying “you need your beauty sleep” at some point in our lives. Turns out, there may be some truth to that saying after all. A study among university students has revealed that the amount of sleep that individuals have daily usually affects their academic performance, as well as the other co-curricula activities. The research was conducted by questionnaires filled out by the participants. The sample for this study consisted of 400 university students from different departments and years. The data collected were analysed using SPSS software and Microsoft Excel.
2. Literature review
In general, it can be said that there are several benefits of sleep. Sleep is essential for our physical and mental health (Anderson, 2015). It helps to restore and repair our bodies from the wear and tear of the day (Dement & Vaughan, 1999). Sleep also plays an important role in consolidating our memories and forming new ones (Diekelmann & Born, 2010).Sleep deprivation, on the other hand, can have detrimental effects on our health, both physically and mentally. It can lead to moodiness and irritability, decreased ability to concentrate and focus, as well as memory problems (Dinges & Pack, 1997). In addition, sleep deprivation has also been linked to a number of health problems such as obesity, heart disease and diabetes (Ng et al., 2010).
The literature review will first discuss the link between sleep and cognitive function, followed by the link between sleep and satisfaction with life. It is important to note that most of the studies reviewed here were conducted among university students or young adults. This is likely due to the fact that most students are experiencing a lot of changes in their lives during this period, which can affect their sleeping patterns. In addition, this age group is also more likely to be suffering from sleep deprivation due to their hectic schedules.
The methodology used in this study was a survey questionnaire. The questionnaire consisted of questions on demographics, sleeping habits and academic performance. In addition, the participants were also asked to rate their satisfaction with life on a scale from 1-10. The questionnaire was distributed online through social media platforms such as Facebook and WhatsApp. A total of 400 university students from different departments and years participated in the study. The data collected were analysed using SPSS software and Microsoft Excel.
The results showed that there was a significant difference between the average amount of sleep received by male and female students (t=4.458, p
