Tomorrow’s my big exam and… and I have so much left to dooooooooo!
Whether it was for psle, o-level or a-level exams, we’ve all been through it. We all know how sleeping less affects grades, but then we still do it? As much as some like to believe “sleep is for the weak”, here are a few reasons why you should reconsider midnight mugging, and snuggle into bed instead:
Sleeping makes room for new information.
Sleep occurs in stages and each one serves a particular purpose for your mind and body. After brief first and second stages, the mind enters a sleep rhythm and the body begins repairing itself, refreshing the immune, muscular and cardiovascular systems.
In the meantime our brain “reboots” sporadically over the 6 to 8 hour rest periods, referred to as Rapid Eye Movement (REM) sleep phases. According to research
, these periods allow the brain to consolidate information from the day while filtering out unnecessary details, all to make room to capture even more the next morning.
This is essential for students to understand and recall the massive amounts of notes during revision periods. Because REM sleep requires a calm and stable resting environment, those who are in a space which is stressful (exams much?) or uncomfortable (books are not pillows) won’t make the most of them, and will quickly forget what they just went over.
And even if you’ve gotten the best private tutor
, they won’t be able to do much if you forgetting everything…
“Each night, when I go to sleep, I die. And the next morning, when I wake up, I am reborn.” ― Mahatma Gandhi
Quantity of sleep > Quantity of revision.
Reversely correlated to age, the amount of sleep one needs decreases, as they get older. While teenagers should get about 8.5 – 9.25 hours of sleep, an average adult only needs about 7-8 hours of sleep
. Not surprisingly, students
are not getting the rest they need.
Preparing for bed maximizes your sleep time and quality. A good revision tip
we can give is to stop using your hand phone
before sleep as the blue light suppresses production of melatonin,
the sleep hormone. Establish a pre-bedtime routine that eases your body into a restful sleep.
You’ll remember better after you wake up.
Sleeping after studying slows down memory deterioration
, meaning you are more likely to recall what you have studied the previous night, suggesting sleep is crucial to the learning process. In fact, a particular research
has shown that attempts to fight fatigue in order to study increase the chances of performing badly on a test.
Long-term sleep deprivation decreases focus and drastically reduces the ability to assimilate new materials. Chances are there will be more mugging over the course of the academic year – variably affecting performance – But if you really want to cram in last minute revisions in the middle of the night… Don’t say I didn’t warn you!
Additionally, if you ever need a tutor
to help for an exam, you know whom to find! 😉
