06 Medical Disclaimer — Sleep Calculator Specific

Our sleep calculator uses a generalized 90-minute sleep cycle model based on population averages from sleep science research. Individual sleep patterns, cycles, and requirements vary significantly based on genetics, health conditions, medications, lifestyle factors, age, and many other variables not captured by our tool.

You should NOT rely solely on our calculator if you:

• Suspect you have a sleep disorder such as insomnia, sleep apnea, narcolepsy, or restless legs syndrome.
• Experience persistent fatigue, excessive daytime sleepiness, or difficulty sleeping despite following our recommendations.
• Have a medical condition that may affect your sleep patterns.
• Are pregnant or recently postpartum.
• Take medications that may affect sleep architecture.
• Are a healthcare professional making clinical decisions for patients.

Always consult a qualified healthcare professional, sleep specialist, or physician for personalized medical advice regarding sleep health.

07 Accuracy of Calculations

Our sleep calculator generates recommendations based on the widely accepted 90-minute human sleep cycle model, personal sleep latency input, and age-group-specific sleep duration guidelines from the American Academy of Sleep Medicine (AASM). However, we make no warranties, express or implied, regarding the accuracy, completeness, reliability, or suitability of the calculations for any particular individual.

The Sleep Quality Score is a relative, directional indicator generated by our proprietary algorithm. It is not a clinical diagnostic measure, does not reflect actual EEG sleep data, and should not be used to evaluate or diagnose sleep disorders.
