What is ACTUALLY happening when you ‘fall asleep’?
In: 34
It’s one of the most mysterious things about the human body. We barely understand sleep and there’s certainly no consensus on what is actually happening when we sleep. It’s an altered state of consciousness and, like almost everything having to do with consciousness, it’s very mysterious. We’re only just starting to understand that there are brain stem repairs happening via spinal fluid exchanges when we sleep, but there’s more to it than that.
Sleep is weird: it improves literally every single human function… and we’re not sure what it is.
There’s a great book called *Why We Sleep* by Matthew Walker, one of the leading sleep researchers in the world. He’s pretty open about how much we don’t understand about sleep. If you want to get up to speed on the little bit we do know and how much more we don’t know about sleep, it’s a worthwhile read/listen.
