How our sleep guides are made

One reader question at a time

Each guide answers one specific question in 800–1200 words of reading text, excluding references. Opening summaries, takeaways, visual explanations and product descriptions count toward that range. We aim to publish one useful original guide each day, checking existing titles and drafts to avoid repetition.

Sources readers can inspect

We prioritise original research, systematic reviews, clinical guidelines and information from established universities, medical organisations and health services. We inspect the supporting text, publication date, population, limitations and relevant conflicts of interest. A prestigious name or a working link alone does not validate a claim. References appear at the end, with citations beside relevant claims.

Evidence and uncertainty

We distinguish research findings from comfort preferences and practical illustrations. Visual guides explain the cited evidence; they do not invent results. A small study is not proof. A source-check date records our evidence check, not a medical review. If a daily scan reveals no meaningful new findings, a guide may explain established evidence without presenting it as new.

Authorship and editorial standards

We do not invent personal experiences, expert quotations, credentials or medical reviewer names. Guides are educational and do not carry a claimed clinical review.

Dates and corrections

Publication dates indicate when a guide first appeared. An updated date reflects a substantive content or metadata change; it is not evidence that every cited study was published or reviewed that day. Corrections should state what changed when a material claim is affected. We retain source and content history in the editing dashboard.

Commercial independence

Relevant guides may suggest optional products with official specifications, meaningful limitations and a no-purchase alternative. When a configured affiliate link is used, we explain the possible commission before the recommendations and beside its button. Ordinary source references remain separate. Commercial arrangements do not validate a sleep claim or determine our evidence assessment. We do not claim product testing or clinical review we have not performed.

Editorial boundaries

Our material helps readers understand lifestyle topics and evidence. It does not diagnose, prescribe, recommend supplement doses or replace an individual assessment. If a source changes or conflicts with a guide, the evidence needs review rather than an automatic stronger claim.
