It’s known that the more sleep we lose, the more prone we are to making mistakes. In other words, pulling an all-nighter to cram for a test can have the opposite effect to what we intend. Also, if we continue to stay up all night and lose sleep for several days in a row, the negative effects of losing sleep can last for a long time—it can take weeks to recover from the accumulated sleep debt.
