Is Napping good for cardiovascular health?

The evidence points that way, though it's not yet conclusive. 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. That's reflected in an evidence score of 60/100 for its role in cardiovascular health, drawn from 6 studies, with an estimated impact on longevity rated limited (30/100).
