This page explains exactly how a sleep guide on NappyTi.me goes from idea to published article, including the primary sources we prioritize and the claims we refuse to make.
Tier 1: government and clinical-society consensus (NIH, CDC, AASM, NIOSH, FDA, WHO). Tier 2: peer-reviewed research in PubMed, Cochrane, Sleep, Chronobiology International. Tier 3: textbooks and university sleep-lab explainers used for context only.
We label claims as strong, moderate, emerging, or anecdotal so readers can weight them accordingly. Single small studies are never presented as settled science.
