About SleepGuru
SleepGuru is a website about healthy sleep. We publish clear answers to everyday sleep questions and free calculators that help you plan bedtimes, wake-up times, naps, caffeine and travel across time zones.
What you will find here
- Calculators that show their method, their assumptions and when their result is not reliable.
- Guides that answer one question each, with numbered citations to health agencies, sleep medicine societies and peer-reviewed research.
Who reviews our content
Drafts are prepared with the help of AI tools from the cited sources and fact-checked against them before they are published. John Smit, a sleep researcher with ten years in the field and a blogger, then reviews each page; pages he has signed off show his name and the review date. Our editorial policy explains the whole process.
