Better Marriage Means Better Health

From TIME: 
Studies have pretty consistently shown that being married and staying married is better for your health. The married population lives longer and gets less sick. But a new study out of Utah suggests that it’s only really happily married people who get the full benefit.
People often think of marriages as happy or unhappy, but they are rarely so easy to classify. Couples in what the researchers called “ambivalent marriages,” unions that are not bad enough to leave but still have distinctly negative attributes (and no, this is not all marriages—just about 75% of them, says the study), do not get many of the advantages of those whose marriages are very fulfilling, the researchers found.
The study, conducted by Brigham Young University psychology professor Wendy Birmingham, and published in the Annals of Behavioral Medicine, asked 94 couples about their spouse’s behavior and what the study romantically called their “interpersonal-functioning.” A quarter of the couples were genuinely happy and had no complaints. But three quarters of the marriages fell into the ambivalent category: mostly their spouses were great, but there was some areas in which they were unsupportive or overly negative.
“There was a high level of positivity in the marriage, but there was also negativity,” says Birmingham, who cites the example of a wife who’s a great partner but not happy with her man’s career, or a husband who’s a wonderful dad and lover but very critical. “These are people who are committed to the marriage. There’s just a lot of negativity, which is negating the positive physiological benefits.”
