Study finds 20-minute workout matches 90-minute nap for protecting memory after sleep loss

Researcher notes different mechanisms: naps clear fatigue signals, exercise sharpens brain response

Analysis clarifies that naps and exercise achieve similar memory outcomes through distinct biological pathways. A nap clears the brain's fatigue signals before learning begins, while exercise leaves fatigue signals intact but produces memory benefit by sharpening the brain's response when new information arrives.
