About MySleepCycles.com
MySleepCycles.com is part of Health Hub Academy, a wellness publisher serving the UK and US. We build free, science-based sleep tools to help you understand your rest.
Why We Built This
We grew frustrated with the state of sleep advice online. Too often, finding out when you should go to bed requires downloading an app, creating an account, handing over your email address, and agreeing to vague data-harvesting policies. The sleep tech industry has increasingly moved towards a model where your personal health data is the product, and basic educational tools are locked behind subscriptions.
We wanted to take a different approach. Sleep is fundamental to human health, cognitive performance, and emotional wellbeing. The science of how we sleep—specifically the 90-minute sleep cycle and the impact of waking during different stages—is well-established and shouldn't be treated as proprietary knowledge.
Our reaction was to build something better: a suite of free, evidence-based calculators that run entirely in your browser. They give you a useful answer instantly, and they never touch your personal data. We built MySleepCycles.com because we believe that everyone deserves access to practical, science-backed tools to understand their rest, without having to navigate paywalls, sign-up forms, or privacy-invading tracking.
What Makes Us Different
Genuinely free
There is no premium login wall. All of our sleep calculators are available to everyone, at no cost, forever.
Genuinely private
We do not collect personal sleep data. There are no accounts, no sleep diaries stored on our servers, and no behavioural tracking.
Genuinely science-based
Calculators built on the 90-minute cycle model and consensus sleep research from the NHS and the American Academy of Sleep Medicine.
Our Editorial Process
- • All articles are reviewed against current sleep science consensus.
- • We use plain English and explain any necessary medical or scientific jargon.
- • We link directly to peer-reviewed sources and institutional guidelines where claims require them.
- • We do not provide medical advice — we point readers to qualified professionals where appropriate.
- • Articles are dated and updated when significant sleep research evolves.
Who We Are Not
We are not a sleep clinic. We do not diagnose conditions. We do not sell supplements, mattresses, or sleep gadgets. We are a publishing site built for people who want to understand how sleep works and make practical improvements to their routines.
