Not Medical Advice
SleepCalc is an informational tool only and does not provide medical advice, diagnosis, or treatment. The sleep calculator, sleep cycle calculator, and all content on sleep.vspic.com are intended for general educational purposes. They are not a substitute for professional medical advice from a qualified healthcare provider.
Always seek the advice of your physician or other qualified health provider with any questions about a medical condition, sleep disorder, insomnia, sleep apnea, or any other health concern.

Accuracy of Calculations
Sleep cycle calculations are based on general averages — specifically 90-minute cycles and a 15-minute fall-asleep buffer. Individual sleep patterns vary based on age, health, lifestyle, and genetics. Results from our calculator are estimates and may not be accurate for every person.
No Guarantees
We make no guarantees that following our calculator's recommendations will improve your sleep quality, eliminate grogginess, or produce any specific health outcome. Sleep is complex and influenced by many factors beyond timing.
