Provisional grade. This entry carries a baseline score generated from the standard framework but not yet confirmed by rater review. The dimensions, the citations behind them, and the grade may all move.

What the evidence shows

Sleep duration and quality are among the most consistently associated exposures in observational aging research, across very large cohorts. The gap is interventional: trials that deliberately change sleep and then measure a hard health outcome are scarce, so the causal step is largely inferred from association rather than demonstrated directly.
