The only time I make my bed is when I change the sheets. That’s once a week, and I only make it then because my mother instilled it in me.
Not making it everyday saves time but more importantly airs everything out and deprives bacteria of moisture. That, makes it less stinky and lets my bedding last longer.
I sleep hot, it doesn’t matter what the ambient temperature is. Vermont in winter? Heating is off in my bedroom, and I have a leg out.
Edit: seems like this isn’t unpopular. It was a random thought that popped in my head. Everyone I have explained this to thinks it’s weird.
I understand the tidy thing, everything else in my bedroom is quite tidy, my life really, with the notable exception of my thought processes.
What?
When you sleep under covers, you sweat (and potentially leak other fluids) and immediately making your bed traps any moisture against the sheets. Leaving your covers pulled down lets your sheets air out a bit. Of course you can wash your sheets, but cleaning a mattress is much trickier.
If you have a mattress pad under your sheets, and you change your sheets regularly, it shouldn’t be an issue. If you don’t, then the mattress may end up smelling of mildew and fungus.
I’ll bet local weather plays a big factor in how fast that occurs, like how clothes washers that tend to get stinky a lot faster in hot and humid locations compared to cool and dry ones.

I go back and forth using a pillow. If I do use one I hang it up everyday to air out.
