This Is What Happens to Your Brain When You Don't Get Enough Sleep

Sleep is a basic biological necessity that profoundly affects our day-to-day life as well as our long-term well-being. After just one bad night's sleep, the quality of our entire day can be compromised—we feel sluggish, less motivated, less adept and moodier. When lack of sleep begins adding up, though, the effects are exponential. The body and brain quickly begin to suffer the consequences of that missed shut-eye. Long story short, what happens when you don’t get enough sleep isn’t pretty. In fact, sleep deprivation is so detrimental to one’s mental and physical health that it’s even been used by the CIA as a controversial method to interrogate detainees.

Meanwhile, we often fall victim to sleep deprivation due to poor sleep hygiene, insomnia, or simply sacrificing sleep to be awake longer doing other things. And while it’s possible to bounce back from an all-nighter here and there, regularly not getting enough sleep can have some serious side effects.
