Sleep is when your brain files what you learned
A landmark review of sleep research shows memory is not fixed when you learn something, but hours later, while you sleep. Cutting sleep after a day of meetings or study quietly throws away part of the work. If tomorrow matters, the most productive thing you can do tonight is go to bed.
This is a short takeaway in our own words, not a reproduction of the study. For the method, the sample and the caveats, read the original. Mind lives inside the Booking Minds app under the brain icon, where you can save and share each piece.
