Disclaimer

Not medical advice

Nothing on this site should be interpreted as professional medical advice. Sleep disorders such as insomnia, sleep apnea, narcolepsy, restless legs syndrome, and other conditions require appropriate clinical evaluation.

Calculator limitations

Sleep-cycle calculations are simplified estimates. Real sleep cycles vary in length and across the night; the result is not a measurement of your brain activity or sleep stage.

Age-based sleep guidance

Sleep recommendations are population-level guidance from reputable sources and may not fit every individual. Health conditions, medications, work schedules, pregnancy, caregiving, and other factors can change sleep needs.

Affiliate disclosure

Best Time For Bed may earn a commission from qualifying purchases on selected third-party products or links. Affiliate relationships do not turn a product recommendation into medical advice.

Not medical advice

Best Time For Bed provides general educational information about sleep. It is not medical advice, and it does not diagnose, treat or prevent any condition. Always speak to a qualified health professional about your own situation, especially if you have a medical condition, are pregnant, take medicines or care for a child.

Calculator accuracy

Our calculators use average sleep cycle lengths and recommended sleep ranges. Real sleep varies from person to person, so results are estimates for planning only. See how it works.

Third-party links and advertising

We may link to other websites and may display advertising, including Google AdSense. We do not control third-party content, and the presence of an ad or link is not an endorsement. Advertising does not influence our editorial content; see the editorial policy.

Emergencies

If you think you may be having a medical emergency, contact your local emergency number right away. Do not rely on this website in an emergency.
