Sleep Brief is a small editorial site about sleep: how to fall asleep, stay asleep and wake up feeling like yourself. We write for people who want a straight answer and the reasons behind it, without the hype that surrounds so much sleep advice.
How we research
Every guide starts from primary sources. In practice that means:
- Clinical guidance from bodies such as the American Academy of Sleep Medicine, the American College of Physicians and national health services.
- Government health agencies, including the CDC, the National Institutes of Health and the U.S. Food and Drug Administration.
- Peer-reviewed research, with a preference for systematic reviews and meta-analyses over single small studies.
We link those sources inside the article, next to the claim they support, so you can read them yourself. When the research is thin or mixed, we say so. If we can’t verify something, it doesn’t go in.
How we grade the evidence
Supplements and home remedies get one of four grades:
| Grade | What it means |
|---|---|
| Strong evidence | Several good-quality trials or a systematic review point the same way, and the effect is meaningful in everyday terms. |
| Moderate evidence | Some good trials show a benefit, but the effect is small, the studies are short, or results vary. |
| Limited evidence | A few small or early studies, mostly promising but not settled. |
| Weak evidence | Little or no good human evidence, or the better studies found no real effect. |
How we write
Each article opens with a short answer, then gives the detail. We write as an editorial team, and we don’t invent experiences: we won’t tell you we “tried” a mattress or “tested” a supplement when we haven’t. Our gear guides explain what features matter and why, rather than handing out star ratings we can’t back up.
We use AI tools to help with research, drafting and editing. Before anything is published, every factual claim is checked against the sources linked in the piece, and articles are reviewed again when guidance changes. The illustrations on this site are made with an AI image model; we don’t use photographs of real people.
Not medical advice
Sleep Brief is for general education. It can’t diagnose you or replace a conversation with a doctor. Some sleep problems, such as sleep apnea, insomnia that lasts for months, or falling asleep during the day, need professional care. Where that applies, our articles say so plainly.
How we make money
Some pages link to products, and some of those links are affiliate links. If you buy through one, we may earn a commission at no extra cost to you. Pages with affiliate links say so at the top.
Commissions never decide what we recommend or how we describe a product. Nobody pays us to be included in a guide, and we don’t accept free products in exchange for coverage. In the future we may also show ads; they’ll be labeled and kept separate from our editorial content.
Corrections
