It's as if you're taking away time from such a precious thing and you're being selfish to go to sleep.
But sleep is a time when your brain actually does its most important task.
Two things happen when we sleep.
The first thing that happens is you actually start cleansing your brain.
There's a very elegant system that gets activated when we go to the deeper stages of sleep.
It's called the glymphatic system.
And it is made of a type of a fluid that literally washes your brain and gets rid of the debris.
And there are very specialized cells.
There are these tiny cells called microglia.
These are the janitor cells of your brain.
They get activated.
You know how when you're in a building and during the day there is business and people come and go, there's a pile of trash that accumulates in the trash cans.
This janitorial system, you know, comes into the building and then it cleans up.
So when you come back the next day, everything is spotless and clean and it smells great.
That's exactly what happens when we go to sleep.
Your brain gets rid of all of this debris, the amyloid beta protein that has been associated with Alzheimer's disease, the tau tangles, and so many other things.
They get washed away.
The second thing that happens is your memories get organized from short-term to long-term memory.
You know how during the day when you come up with ideas, you write them, you scribble them.
You were scribbling on some papers in the corners and you probably have some post-it notes in your computer in your office.
