Introduction to a magazine article
How much sleep is enough? Lots of studies have found that the less
you sleep, the worse your performance will be. Many studies show that,
generally, if you do not sleep enough, you will do worse in exams.
So, does more sleep mean better exam results? That would be too simple.
For example, you still have to study well in the first place. But research
shows that people who sleep well can also study better.
In this article, we are going to look at the research inmore detail. We will
explain what it means to “study better” and say how much sleep you need.
