This page explains how we research, write, check and update the articles on sleepgood.org, how we use AI, and how we choose the products we recommend.
Our sources
We base our articles on sources you can check:
- studies published in peer-reviewed journals, found through databases such as PubMed;
- health bodies such as the American Academy of Sleep Medicine, the National Institutes of Health and the CDC;
- for products, the maker’s own published details (price, materials, guarantee, regulatory status), any published research on the product, and what buyers report in their reviews.
When an article gives a study result, it names the study, so you can look it up. We do not invent numbers, quotes, experts, test results or customer stories.
Our storyteller, Sarah
Our articles are told through Sarah Ellis, a fictional character, so that sleep science is easier to follow and more enjoyable to read. The pictures on the site illustrate ideas; they do not show real people or real product tests. Like any publisher, we use digital tools to help with research and drafting, and every draft is checked by a person as described below.
How every article is checked
Before an article is published, a person reviews it:
- Every fact, number, price and study detail is checked against its original source.
- Anything that cannot be confirmed is removed or rewritten in general terms.
- Health claims are checked for safety. Products that reduce snoring are never described as a treatment for sleep apnea.
- The title, description, image text and other page details are checked too.
- Product reviews say plainly whether they are based on hands-on testing or on research. We do not claim to have used a product we have not used.
How we choose products
We recommend a product when the evidence and the maker’s terms suggest it can help a specific kind of reader, and we say who should choose something else. Our free snore quiz matches readers to a type of product based on their answers, not on commission. Some links are affiliate links; see our Affiliate Disclosure. Brands cannot pay to be reviewed or to change what we write.
Health topics
Our articles are not written by doctors and are not medical advice. On health topics we explain the warning signs that mean you should see a doctor. Read our Medical Disclaimer.
Corrections and updates
We review our articles when research or prices change. If you find an error, please tell us through our contact page. When we confirm a mistake, we correct it and update the article’s date.
