Eli5: Why cant we just signal to our brain when we want to fall asleep?

718 views

When we lay down at night why our brain does not recognize it and make us fall asleep much easier? Interesting that we have control over so much things but not our own body.

Rather than an on/off switch, a better analogy is like valve. Certain chemicals need time to circulate your brain in order to inhibit the brains activity.

If it were like a dam where you flipped a switch and just flooded your whole brain all at once you would likely die, so it’s more like a slow release mechanism of small pipes.
