Is this an urban myth, or is there a known association between lifting legs before going to sleep, and a reduction in the number of bathroom trips during the night? If so, what is the best time and duration for lifting legs? (I'm looking for basic ways to slightly improve sleep quality here).
One article I've read mentions that elevating the legs can decrease nocturia:
Simple solutions for reducing the number of times you have to void at night include restrict fluids in the evening... elevate the legs during the day (helps prevent fluid accumulation)...
