Why do people get grumpy when they haven't had enough sleep?

Answer #1

Because your brain is not functioning properly. When the body doesnt get basic necessities (food, water, sleep, oxygen being the most basic), the brain isnt functioning at 100% and people get crabby.

Answer #2

probably becuz they dont have enuf rest and are feeling irritable becuz they dont want to deal with matters that they find “petty”

Answer #3

When im tired i get really grumpy like REALLYY. i cant even stand to have my friends talk to me, i just wanna pass out right there. and when they do talk i wanna tell them to shut up.. sometimes my head starts pounding…but yah ppl do get grumpy

Answer #4

It really depends on the person.

Technically no sleep stresses out the brain which in turn stresses you out. This causes you to be easily provoked.

I don’t really get grumpy though. I kind of just… zone out. Lol.

Answer #6
