If you yawn during the day, conk out as soon as your head hits the pillow or re-read this sentence a few times to absorb its meaning, here’s some bad news: You need more sleep.
Scientists still don’t know exactly why we sleep, but according to a near-constant stream of research, most of us need between six and eight hours of shut-eye each night. Unfortunately, only about 30% of us are getting it. That means 70 million Americans suffer from sleep deprivation, a certified public health epidemic, according to the Centers for Disease Control and Prevention.
Sleep deprivation takes an enormous toll on our bodies, including bloodshot eyes, increased blood pressure and a fuller waistline. But what’s equally alarming is the negative impact of sleep deprivation on the brain.
This infographic explains what happens to your brain, and what it means for you, when you don’t get enough sleep:
