Disclaimer

DreamScape provides general educational and planning information. Calculator results are mathematical estimates based on the values entered by the visitor.

Not medical advice

The calculator is not a medical device and does not diagnose, prevent, or treat a health condition. It cannot measure sleep stages, sleep quality, or an individual's biological sleep cycle.

Results can vary

Sleep timing and cycle length can vary from person to person and from one night to another. The default 90-minute setting is a planning assumption, not a universal biological rule.

Use your judgment

Do not use a calculator result to ignore professional advice, safety needs, school or work requirements, or signs that you are not getting adequate rest. If you have persistent or concerning sleep difficulties, speak with a qualified healthcare professional.

Accuracy

We aim to keep the calculator and explanatory material clear and useful, but we do not guarantee that every estimate will suit every visitor or circumstance.
