Researchers have recently published the results of a study that followed the marriages of around 1,600 people over a 20-year period to uncover the effects of marital happiness on physical health.
According to co-author Cody Hollist, from the University of Nebraska-Lincoln, there is a recognised link between health and the happiness of marriage, but it is not clear whether a happy marriage creates good health, or whether a bad marriage leads to poor health.
“There is no way to tease out what caused what,” he said. “But it is clear that marital quality and health run in tandem.”
