About
Science-backed sleep,
no shortcuts.
The Sleep SOP exists to make peer-reviewed sleep science readable and actionable — without the supplements, gadgets, or wellness marketing that dominates the conversation.
What this site is
The Sleep SOP is a sleep improvement resource built on a simple principle: every recommendation we make traces back to a peer-reviewed primary source. Not a secondary article about a study. Not a brand-funded white paper. The actual study, with the actual DOI, linked inline.
Sleep is one of the most evidence-rich areas of health science — yet most of what gets published online about it is either oversimplified, commercially motivated, or simply wrong. We set out to fix that for a general adult audience who want to understand what the research actually says.
Our editorial principles
-
01
Primary sources only. Every factual claim links to the peer-reviewed paper it comes from — not a secondary source, not a press release. If we can't cite it, we don't publish it.
-
02
Balanced where the evidence is mixed. We don't manufacture certainty. Where research is genuinely contested or preliminary — as with melatonin for general insomnia, or cannabis and sleep — we say so explicitly.
-
03
No sponsored science. We do not accept payment to promote specific supplements, devices, or interventions as scientifically validated. Affiliate links are disclosed and do not influence editorial content.
-
04
Updated when the evidence changes. Science moves. When a cited study is superseded, challenged, or revised, we update the content to reflect the current consensus — not the original publication.
-
05
Plain language, not dumbed down. We explain the mechanisms — adenosine, circadian rhythm, sleep architecture — because understanding why something works makes it far more likely you'll actually do it.

What this site is not
The Sleep SOP is not a medical service. Nothing on this site constitutes medical advice or replaces the guidance of a qualified healthcare professional. If you have a diagnosed sleep disorder — including insomnia disorder, obstructive sleep apnoea, narcolepsy, or restless legs syndrome — please consult a doctor or sleep specialist. The evidence-based interventions we describe (particularly CBT-I) are best delivered by a trained clinician for clinical populations.
