During sleep, the body tone drops, breathing slows down, blood pressure decreases, if you exceed your normal hours, the body tone will not increase and this will happen slowly and hard for you.
It can also be a chronic lack of sleep, autonomic dysfunction of the GMF (VSD), a lot of nerves, and so on.
And also, the more lazy you are, the more you want to be lazy, so the same mechanism is quite possible here.
