A good fight with your spouse could be good for the health, a new study has found.
Couples who suppressed their anger have a mortality rate twice as high as those in which at least one partner stands up for themselves, according to the study which tracked 192 US couples for 17 years.
"When couples get together, one of their main jobs is reconciliation about conflict," said lead author Ernest Harburg, an emeritus professor with the University of Michigan.
"The key matter is, when the conflict happens, how do you resolve it?" he said.
"If you bury your anger, and you brood on it and you resent the other person or the attacker, and you don't try to resolve the problem, then you're in trouble."
Previous studies have shown that suppressing anger increases stress-related illnesses like heart disease and high blood pressure.
This study looks at how suppressed anger and the resulting buildup of resentment in a marriage affects overall mortality rates.
Harburg and his colleagues used a questionnaire to determine how the spouses responded to behaviour that they perceived as unfair.
Both spouses suppressed their anger in 26 of the couples while at least one spouse expressed their anger in the remaining 166 couples.
At least one death was recorded in half the couples who suppressed their anger, whereas only 26 percent of the other couples suffered from the death of a spouse.
And the anger-supressing couples were nearly five times more likely to both be dead 17 years later, the study found.
The study was carried out in a small, predominantly white and middle class town in Michigan and most of the women were "housewives" born before the sexual revolution.
An upcoming analysis of survival rates 30 years later will yield more reliable results, Harburg said.
