Sleep plays an active role in building memory. While we sleep, the brain replays what we experienced during the day and moves important information into long-term storage. In several experiments, students who slept after studying a list of words remembered more of them than students who stayed awake. Similar results have been reported for skills such as playing the piano.
Many students, nevertheless, cut their sleep before examinations. They stay up late to review their notes one more time. The extra hours feel productive, but a tired brain tends to retain little of what it reads. Studying late into the night, in short, often costs more than it gives.

睡眠は、記憶を作るうえで積極的な役割を果たしています。眠っている間に、脳はその日に経験したことを再生し、重要な情報を長期の保管場所へ移します。いくつかの実験では、単語のリストを勉強した後に眠った学生の方が、起きていた学生よりも多くの単語を覚えていました。ピアノの演奏のような技能についても、同じような結果が報告されています。それにもかかわらず、多くの学生は試験の前に睡眠を削ります。ノートをもう一度見直すために、夜遅くまで起きているのです。増やした時間は成果があるように感じますが、疲れた脳は読んだ内容をあまり蓄えられない傾向があります。要するに、夜遅くまでの勉強は、得るものより失うものの方が多くなりがちです。
