So if I remember right there is a sort of fatigue that is restored best by sleeping but there are supposed to be other ways to restore it also like eating certain foods or meals. I think the goal was to make sleep the most optimal way but to not interrupt a play session there are also less optimal alternatives like eating certain food so you can keep playing. Not sure if this is till current because it was in a QnA like 2 years ago lol.
