Maybe you could change to showering in the morning.

I don't particularly want to add showering to my morning routine, but today I did shower between lunch and dinner, which is something.

what sort of things are you keeping on the bed?

Usually things that I put somewhere inconvenient the night before. In particular my chair, and for the past few nights the top of my suitcase. But yesterday I put enough clothes into my suitcase that I can't shut it any more, so I seem to have found somewhere less inconvenient for the things I was putting on top of it. (I may have moved them into my suitcase.) So right now it's mostly just a pile of documents from my chair, which is what I'm used to. I can just pick up the whole pile and move it without thinking about where to put anything.

But it depends what I've been doing through the day; yesterday it was particularly bad because I received a package of electrical components.
