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

Question

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.

Answer 1

I don’t think it is good to fall asleep every time you just lay down, that wouldn’t be a very wise choice evolutionary wise with predators and all. But yeah, would be nice if you can find an offswitch somewhere
