There's a reason that sleep deprivation is used as a form of torture-it's killer on your body. In fact, if you miss enough sleep, it can cause you to drive as erratically as someone who has a blood alcohol level of .08 or higher. In other words, missing too much sleep can impair you in much the same way that being intoxicated can. Multiple studies have documented the negative effects that lack of sleep has on brain function. Just one night of missed sleep can significantly dull the centers of your brain responsible for memory, concentration, and language... -meaning that your all night study session might have done more harm than good. And if you continually skimp on sleep, you may experience memory loss, a decreased desire for sex, and reduced tolerance for alcohol. In the end, you'll definitely gain more by catching some zzzs than you will by cramming all night. It's important to be mindful of the impact on all-nighter can have on your body and mind.
