General planning, not medical advice

Sleep Better Timer provides general wellness information and rough time estimates. It does not diagnose, prevent, treat, or cure insomnia, anxiety, sleep disorders, or any other medical condition.

The calculator uses an approximate sleep-cycle length. Actual cycles, time to fall asleep, awakenings, sleep needs, and morning alertness vary between people and from night to night. A displayed time is not a guarantee of sleep quality or how you will feel.

Do not use this website to make safety-critical decisions about driving, operating equipment, medication, or work that requires alertness. If sleep problems are persistent, severe, or affecting daily life, consider speaking with a qualified healthcare professional.

In an emergency or when you may be in immediate danger, contact local emergency services.
