After two straight weekends of awesome globetrotting madness, I finally had a weekend to myself and could make use of a couple of terms my host mom in Nishiaizu taught me:
骨を休め – literally “rest one’s bones,” take a physical rest
羽を伸ばす – literally “spread one’s wings,” a similar pattern but also includes a mental rest aspect, and another alternative is…
鬼の居ぬ間に洗濯をする – literally “do laundry while the oni is away,” where oni = unpleasant boss-like person/situation that oppresses you
