I recently had an idea I wish I'd thought of a few years ago, but if you have severe difficulty* changing bed sheets, you can actually break the job up over a few days. This is what I've started doing, divided up to have roughly equal energy demands:

Day 1: Change duvet cover
Day 2: Change pillow cases and bed sheet
Day 3: Rest, if needed
Day 4: Wash removed bedding in washing machine

• if you have orthostatic intolerance, ME/CFS or long covid you might relate to this. It also helps mentally breaking down the tasks like this during periods of intense brain fog.
