Insomnia CAN kill you.
More Info: A long-term study, conducted by researchers at the University of Wisconsin and the Old Dominion University Norfolk, VA, concluded that chronic insomnia is associated with an increased risk of death. The study was funded by grants from the National Institute of Health.
The authors of the study set out to analyze the association of mortality and chronic insomnia independent of existing health conditions.
Participants of the Wisconsin Sleep Cohort Study were asked to complete surveys over an eleven-year period in 1989, 1994, and 2000 respectively. The survey included questions associated with conditions of insomnia such as difficulty falling asleep, awakening repeatedly, and difficulty falling back asleep. The authors considered any participant reporting insomnia symptoms on at least two of the surveys to have chronic insomnia.
In 2009, twenty years after the initial survey was distributed, the authors researched all-cause mortality cases through a social security death index search. The authors then adjusted mortality hazard rations based on existing chronic conditions, age, sex, and BMI.
