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.
Fwiw I do both.
First after I get out of the bed, especially if I was hot & sweating, I throw the sheets off (turned over to expose the part touching me to the air) and leave it that way. As you say, this “unmaking” is the important part for sanitary reasons.
Then after like an hour make the bed, b/c of how it makes me feel inside.
Obviously your schedule may impose constraints - e.g. if you have to leave quickly after waking then make the bed when you get home?
