Sleep Habits Affects Performance

It’s 2:33am (how apt!). You’re up either mugging for your upcoming exams, or rushing to complete a major project (that’s me here). And that’s because you’re determined to do well.You’re tired. Your mind drifts off. You wonder if you’re the only person staying up at this ungodly hour trying to make sense of the tiny scribbles and the words swimming in front of you.

Well, here’e answering your question: you’re not alone. But hold on, that’s NOT a good thing. By sacrificing sleep, does it translate into better academic performance? What college students are unaware is that a disruption of good sleep habits can reduce their academic performance (Jenkins, Soper, Woller, Johnson & Faes, 2009).

In today’s ever-changing society, college these days is no longer comparable to those in the past, and students in college are increasingly sleep deprived.

According to Lack (1986), 17% of students exhibiting symptoms of delayed sleep phase syndrome (a shift in your natural circadian rhythm ie. sleeping at 4am everyday and only waking up at 12pm) reported poor academic performance.

This is because the lack of sleep affects your health in memory consolidation, visual-motor reaction, vigilance, attention to task... just to name a few, and inadvertently has a negative impact on learning.

So just how tired are college students?

"College students suffer a decreased level of sleep quality [as] compared with a 'normal' adult population" 

(Buboltz et al., 2001, p. 133).

Moreover, more than half 50% of the population acknowledged morning tiredness, and nearly three quarters believed that they do not get enough sleep during the week.  More interestingly, Bulboltz et al. found out that if a student knew he had received little sleep, he would behave so (2001). This reminds me of the self-fulfilling prophecy theory I once read about where when one believes he or she (in this case, suffer from lack of sleep), he or she will feel tired, and this will lead to feelings of restlessness, unmotivated and hence do not have the perseverance to complete the day’s task.

Therefore, it’s better to get rid of the daily fatigue by practising good sleep hygiene! Refer to Cameron’s post for more tips to better sleep!
