We think of being exam smart, having the right study techniques, studying for longer hours and more frequently as being the key to academic success. But one of the ways to boost school performance is rooted in doing the opposite: nothing. More exactly, sleeping.
A study on medical students in 2012 showed that those experiencing more stress and poorer sleep before exams, performed more poorly than their peers, while a 2010 meta- analysis of 17 studies found that children and teenagers who reported feeling sleepy were those with poorer academic performance. In short, inadequate sleep either from not sleeping adequate durations or having interrupted sleep can spell trouble for maintaining learning performance at school.
And sleep quality has a profound effect on our daily functioning. Studies suggest that getting adequate dream sleep (also known as rapid eye movement or REM sleep) maintains our mood, mental wellbeing and problem solving abilities. These websites offer a detailed explanation of how sleep is crucial to our cognitive functioning: NIH, Harvard Medical School, American Psychological Association (APA), WebMD, Harvard Business Review, the Guardian, Huffington Post, Mayo Clinic.
In keeping with the existing literature on the importance of sleep, as this article explains, recent studies show this to be true. Sleep research published in last year demonstrated that sleep is critical to maintain a healthy lifestyle – specifically, not having adequate sleep impacts us both physically and mentally (Science Daily, 15 Oct 2013).
A recent Swedish study found that missing just one night of sleep is associated with signs of brain tissue loss (Science Daily, 31 Dec 2013) – a conclusion shared by other researchers. A literature review published this year explains that sleep allows the the brain to strengthen neural connections (“SHY hypothesis explains that sleep is the price we pay for learning”, Science Daily, 9 Jan 2013).
In short, not having enough sleep impairs our ability to make decisions, remember things, and learn new things. And school’s about learning new things and remembering them.
Here’s a few things you can do:
1. Cultivate good sleeping habits
Discovery Health has 10 useful tips. Not every tip may be appropriate or useful to everyone but we need to start somewhere. And a dark room can help: here’s why. And here are few more ideas for boosting your sleep efficiency.
2. Read about sleeping
Try the book Why We Sleep: The Functions of Sleep in Humans and Other Mammals. You might find yourself soon extolling the virtues of sleep to other busy bees.
3. Sleep the sleep
Children will do as they see. Parents who don’t practice good sleeping habits or play an enabling role for their children to have poor sleeping habits, probably aren’t going to have children who get enough rest (to do their bestest at school)!
