In short: CircadianIQ is for general education only. It is not a substitute for professional medical advice, diagnosis or treatment.

Educational information only

All calculators, quizzes, articles and other content on circadianiq.com are provided for general information and education. They are not medical advice, and using this site does not create a doctor–patient relationship.

Calculator results are estimates

Our tools use average values from sleep research, such as typical sleep cycle length, caffeine half-life and circadian timing. Your own body, health conditions, medications, age and lifestyle can produce very different results. Treat every result as a rough starting point, not a prescription.

Talk to a doctor

Always consult a qualified healthcare professional before:

  • taking or changing melatonin, sleep aids, supplements or any medication;
  • making major changes to your sleep or work schedule if you have a health condition, are pregnant or nursing;
  • using sleep-timing advice for babies or children (speak to your paediatrician).

See a doctor if you have ongoing insomnia, loud snoring or pauses in breathing during sleep (possible sleep apnea), excessive daytime sleepiness, or any symptom that worries you.

Emergency: If you think you may have a medical emergency, call your local emergency number (in Pakistan, 1122) immediately.

Safety while drowsy

Never drive or operate machinery when sleepy, whatever a calculator says about your sleep.
