Doing the dishes or other chores doesn't work for me at all but showers are great. When I was at Apple one of the few unalloyed good aspects of the spaceship campus were every section had showers available.

I'd take a brisk walk around the spaceship and then hit a shower. It was a great way for me to avoid an afternoon slump and let me do a lot of background processing in relative peace.
