It was a particularly tempestuous night. The rapid changes in barometric pressure resulted in a storm outdoors, but also one inside - my body.
A contrast bath is a process of soaking your hands in tubs of hot (test first!) and cold water, for alternating cycles of twenty minutes.
As I was doing the dishes that morning - hot for washing and cold for rinsing - I noticed that my hands began to feel better. I was creating a contrast bath without being aware that I was doing so!
Who doesn't like a two-for-one deal? Dishes done. Fingers flexible.
So, when your hands are puffy and hot, forego the dishwasher. Load a basin of cold water alongside your hot wash water and do as Madge suggests - soak in it!
