Does Napping actually make a difference, or is it overhyped?

Multiple independent dose-response meta-analyses of habitual daytime napping and health outcomes converge on a nuanced, U- or J-shaped pattern rather than a simple linear relationship: several analyses find longer or more frequent napping (often defined as more than 60 minutes, or napping most days) is associated with higher cardiovascular disease and all-cause mortality risk, while shorter, less frequent napping shows a more neutral or even modestly favorable association. Weighing the data: Napping looks an early-stage, lower-priority area for now — the evidence is only moderate (60/100), and its estimated impact (30/100) is on the lower end too.
