Eli5: Why do we need to sleep so much, what happens in the body when asleep that cannot happen while normal resting or relaxing? Or is it just for the brain?
In: Biology
I learned about this in a neurobiology course I was taking at my university! I’m on my phone right now, but there are a few hypotheses as to why this is. Two are shown below:
* It has been hypothesized that sleep helped us survive. It was seen to be beneficial to sleep at night, since we could not see and our likelihood of getting killed while roaming
* Sleep has been shown to aid in learning and memory cognition. Basically if you learn something and then sleep on it for a bit, you’ll have a better chance of retaining the information.
