How Sleep Shapes Our Day
睡眠如何塑造我们的一天
We often treat sleep as the time left over after everything else is finished. In fact, sleep is when the brain sorts, stores and repairs what happened during the day.
我们常把睡眠当成「其他事情都做完之后剩下的那段时间」。事实上，睡眠正是大脑整理、储存和修复白天经历的时候。
After a poor night, we do not simply feel tired. We react more slowly, remember less, and find it much harder to control our moods.
睡不好一晚，我们不光是觉得累。我们的反应变慢、记住的更少，情绪也明显更难控制。
Students who sleep well before an exam usually do better than those who study all night. The extra hours of revision are often paid for by a slower and far less accurate brain.
考前睡好的学生，通常考得比通宵复习的学生更好。那多出来的几小时复习，往往是用一个更迟钝、更不准确的大脑换来的。
Good sleep is not a luxury or a reward for finishing work. It is part of the work itself, and it deserves a fixed place in the day.
好的睡眠不是奢侈品，也不是完成工作后的奖励。它本身就是工作的一部分，应该在一天里占一个固定的位置。
