Accuracy and Limitations

Scientific Basis and Individual Variation

Our calculator is based on the established scientific understanding that human sleep typically follows cycles of approximately 90 minutes. However, it's important to recognize that:

  • Individual sleep cycles can vary from 70-120 minutes
  • Sleep cycle duration can change based on age, health status, and other factors
  • The 14-minute sleep onset time used in our calculations is a population average

Calculator Limitations

Our sleep calculator:

  • Provides general recommendations based on population averages
  • Cannot account for individual sleep architecture variations
  • Does not consider environmental factors that may affect sleep
  • Cannot diagnose or treat sleep disorders

We strive to provide accurate information, but you should use our recommendations as general guidance rather than precise prescriptions.
