This Video Explains Why Sleep Is So Important

It might seem crazy, but scientists aren’t absolutely sure why we need sleep. Sure, we know important processes happen during sleep, like cell repair, but any more than that is pretty much very well-educated speculation.

Even though they might not be conclusive, this video by YouTube Channel It’s Okay To Be Smart attempts to give us some answers, as well as chucking in some really interesting sleep facts for good measure.

There’s even one about dolphins and some weird sea-dwelling worms.

So if you’re as interested in sleep as I am, or you just want to hear more about the aforementioned sea-worms (who doesn’t, tbh), you won’t regret giving it a watch.
