I don't like changing a hot engines oil because I usually end up getting said oil on my skin.
I once overheard a fleet maintenance manager argue with a mechanic to start the engine for 1 min to suspend any sludge before an oil change. My takeaway after having seen the inside of some high mileage engines is that baked on crud can only be physically removed.
My normal practice is to change it the morning after it ran the day before or else in the evening after it ran in the morning. Ambient temps from 70 - 90 F.
I don't think engines have "feelings". They don't change their inanimate state by anything other than off to on, to cold, to fast, to hot, to hot + to dirty = death.
