Bottom line

Read Off Label grades Sleep as S (9.7/10) based on very strong evidence, high benefit magnitude, and a very low-risk safety profile.

U-shaped mortality curve — both <6hr and >9hr associated with increased all-cause mortality.

Studied, labeled, or reported-use context: 7-9 hours/night; consistent schedule; dark, cool room — N/A; not individualized guidance.

What the evidence says

U-shaped mortality curve — both <6hr and >9hr associated with increased all-cause mortality. Arguably the single highest-ROI intervention on the entire list.

Mechanism

Glymphatic waste clearance; memory consolidation; hormonal regulation (GH, cortisol, leptin/ghrelin); immune function

Studied, labeled, or reported dose & route

7-9 hours/night; consistent schedule; dark, cool room

This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
