Many of us already know that sleep is important. Most people function much better when we get the recommended daily 7-9 hours of sleep, but did you know that sleep is actually critical to our survival? 

In the SciShow episode “Sleep: Why We Need It and What Happens Without It”, host Hank explains that humans will die more quickly of sleep deprivation than of starvation.

So, the next time you’re thinking about pulling an all-nighter to finish an assignment, or working a double shift without a break to rest, think again! Sleep is important!
