Honey, stop nagging - you're killing me

Couples who have heated arguments with each other are more likely to have health problems that those who do not, new research suggests.
A new study based on 150 healthy, older married couples found that women who are hostile toward their husbands during disagreements are more likely to have hardening of their coronary arteries.
For men, being controlling -- or being married to someone who is -- promotes atherosclerosis.
"It was intriguing that we could find a relationship between a six-minute behavioural snapshot of couples talking about an argument they have, and a silent but very serious condition in their coronary arteries," said researcher Tim Smith, a professor of psychology at the University of Utah in Salt Lake City.
"These were all people who were outwardly healthy, but some had advanced atherosclerosis."
Prof. Smith's team interviewed married couples, mostly in their early sixties, who had no history of cardiovascular disease. The couples were taken into the lab and videotaped as they discussed something -- money, in-laws, kids -- that they had had disagreements about in the past.
Researchers who watched the tapes coded every comment into categories.
The list of hostile and dominating statements, for instance, included phrases such as, "You can be so stupid sometimes" and "You're too negative all the time."
The warm and submissive list had statements like: "Oh, that's a good idea, let's do it." :lol: :lol: :lol:
Some couples were so hostile they were referred to marriage counsellors. (The graduate students noted that couples are far more likely to be nicer to each other in front of strangers than they are when they're home alone.)
Two days later, each couple had a CAT scan to check for calcification of the arteries that supply the heart muscle with blood. Plaque is a build-up of fat, calcium and other substances that, over time, can lead to narrowing of the arteries and an eventual heart attack.
The researchers found that the more hostile and unfriendly the women were during the six-minute discussions, especially if their husbands were, too, the more severe the hardening of their arteries.
However, their arterial health was not influenced by whether they or their husband acted in a controlling or dominating way.
Men, on the other hand, who were more dominant or controlling, or whose wives were, were more likely than other men to have more severe hardening of the arteries.
The researchers haven't proved a cause and effect, but the findings jibe with what the literature says about psychological sex differences in what people find stressful in their lives.
"All the literature suggests women would be more attuned to, and as a result more upset by, difficulties in friendliness versus hostility, or how well people are getting along," Prof. Smith said in an interview, adding men are more bothered by who is in charge.
None of the findings on the CAT scans was a medical emergency.
