"In your everyday life, do you experience conflicts with any of the following people?"
- Other family
A Danish health survey asked almost 10,000 people between ages 36 and 52 to answer, "always," "often," "sometimes," "seldom," or "never" for their applicable relationships.
Eleven years later, 422 of them were no longer living. That’s a typical number. What’s compelling, Rikke Lund and her colleagues at University of Copenhagen say, is that the people who answered "always" or "often" in any of these cases were two to three times more likely to be among the dead. (And the deaths were from standard causes: cancer, heart disease, alcohol-related liver disease, etc.—not murder. Were you thinking murder?)
The association accounted for variables like cohabitation, chronic physical and mental disorders, depressive symptoms, and emotional-social support. Worries emanating from close relationships like partners or kids were more strongly related to mortality than worries from those more distant. But still, even if you are not overtly trying to kill your neighbor, it would seem that a duplicitous relationship could be ravaging you both.
Lund and other public-health researchers published this association in the current Journal of Epidemiology and Community Health. They also saw a similarly morbid trend when those same 10,000 Danes answered a slightly different question: “In your everyday life, do you feel that any of those people demand too much of you or seriously worry you?” Frequent worries or demands from a partner or children were associated with 50 to 100 percent increased risk of dying during the 11-year followup.
The conclusion, then: "Stressful social relations are associated with increased mortality risk among middle-aged men and women."
We could argue all day about the definition of middle-aged here. But that would only kill us faster. Instead, stop reading this immediately and go tidy up all your relationships. If they are beyond repair, sever them completely. Then make a list of all the things you’re going to do with the extra life you just gained. If you don’t make a list, you’ll never do them.
In arguably more practical terms, Lund and colleagues suggest another course of action: "Skills in handling worries and demands from close social relations as well as conflict management—within couples and families and also in local communities—may be important strategies for reducing premature deaths."
Epidemiological studies like this have told us before that stressful relationships, especially marriages, are associated with cardiovascular disease, immune dysfunction, and endocrine dysregulation. We’re not certain why. Studies have implicated inflammatory cytokines and elevations in the stress hormone cortisol. This study is unique in looking directly at death, though. It’s especially interesting because positive, protective effects of social relations on health are widely known. Like exercise, relationships shape individual health outcomes throughout life.
