Using OptimalSleep.

Educational information

Our guides and tools help adults explore everyday sleep questions. They do not create a clinician-patient relationship, diagnose a condition, prescribe treatment, or guarantee an outcome.

Models and suggestions

The caffeine explorer makes simplifying assumptions and cannot predict an individual’s sleep. The bedroom check and notebook are practical reflection tools, not validated clinical assessments.

Individual care

Consult a qualified professional about persistent symptoms or decisions involving a health condition, medicines, pregnancy, or a child. Do not delay care because a tool or general guide seems reassuring.

Your copy of the notebook

You may print the notebook for your own use. Device storage can be cleared or become unavailable; keep a separate copy of anything you need.
