Summary

Optimal survival is linked to 7 hours of sleep. Sleeping 8 hours or more, or less than 6 hours, increases mortality risk. Insomnia itself does not appear to be a risk factor for mortality.

Area of Science:

  • Sleep Medicine
  • Epidemiology
  • Public Health

Background:

  • Many individuals believe 8 hours of sleep is necessary.
  • This belief influences treatment strategies for insomnia and sleep duration.
  • Understanding sleep's impact on survival is crucial for public health.

Purpose of the Study:

  • To investigate the association between sleep duration, insomnia, and mortality.
  • To determine optimal sleep duration for survival.
  • To assess if insomnia is an independent predictor of mortality risk.

Main Methods:

  • Utilized data from the American Cancer Society's Cancer Prevention Study II (CPS-II).
  • Surveyed over 1.1 million participants on sleep habits and insomnia frequency in 1982.
  • Employed Cox proportional hazards survival models to analyze mortality up to 1988, controlling for confounding factors.

Main Results:

  • The highest survival rates were observed in individuals sleeping approximately 7 hours per night.
  • Sleeping 8 hours or more, or 6 hours or less, was associated with significantly increased mortality risk.
  • Insomnia reports were not linked to increased mortality, but prescription sleeping pill use was.

Conclusions:

  • Patients can be reassured that short sleep and insomnia have minimal risk independent of other health conditions.
  • A slight increase in mortality risk may be associated with sleeping 8 or more hours and with sleeping pill use.
  • Further research is needed to establish causality for these associations.
