I'd like to challenge a common belief today: that sleep is wasted time. In fact, while you sleep, your brain is busy doing some of its most important work, especially the work of memory. During deep sleep, the brain replays the experiences of the day, strengthening the connections that store useful information and trimming away the trivial. This is why studying right before bed can be so effective; the sleep that follows helps lock the material in. Different sleep stages handle different jobs, too. Slow-wave sleep tends to consolidate facts and events, while the dreaming stage, REM, seems to support skills and emotional balance. The practical lesson is clear. If you pull an all-nighter before an exam, you may feel you have studied more, but you have actually robbed your brain of the very process that turns studying into lasting memory.
