People who are happier are usually also healthier—and not just because they’re happy about being healthy. When humans feel good, they’re more likely to be active and less likely to attempt to cheer themselves up with cheeseburgers, ice cream and a two-day Game of Thrones marathon. 
  
 But a new study suggests that people whose spouses are happier are probably also in better shape, even independently of their own happiness. In fact, the study’s data suggests that people with a happy partner are 34% more likely to be healthy than those married to a downer. 
  
 The study, out of Michigan State university looked at about 2,000 older married heterosexual couples in the Health and Retirement Study over six years, from 2006 to 2012 and found that those who reported a happier spouse also reported feeling better overall. 
  
 “Participants with happy partners were significantly more likely to report better health, experience less physical impairment, and to exercise more frequently than participants with unhappy partners,” says the study, “even accounting for the impact of their own happiness and other life circumstances.”

 The authors propose a couple of reasons why a happy person might improve the health of their lover. First, a happy spouse is a better caretaker; he or she is more likely to have the emotional energy to look after a significant other, making sure they’re O.K., have taken their medications and are looked after when they’re ill. 
  
 Secondly, people with a positive outlook are more likely to be playing the long game; they eat better, they exercise, they sleep regularly, they make plans and avoid doing self-destructive things because they feel good about the future. And they bring their companions along for the ride. “Happy people drag their spouses out of bed to go exercise, and they encourage them to eat healthier,” says Bill Chopik an associate psychology professor at MSU, and lead author of the study. 
  
 And thirdly, happy spouses make life easier for their partners because their partners aren’t stressed by the fact that their closest companion is always in a bad mood, and they’re not exhausted by efforts to jolly them along or under constant pressure not to upset them. 
  
 One of the ways the researchers think this works is that the happy soul becomes a proxy for their partner, so the gloomy individual behaves as a non-gloomy person would. “It’s compensatory,” says Chopik. “Another person’s happiness is filling you up, so you do these healthy things.” 
  
 The study adjusted for gender, wealth and educational attainment and also for people who were desperately ill or whose partners were, which would obviously have a big impact on happiness. 
  
 Surprisingly, there was no difference in these outcomes between husbands and wives. “There’s a sense that women’s manage their husbands’ health, but it appears that the amount your spouse’s happiness affects your health doesn’t vary across gender,” says Chopik. 
  
 It’s hard to know what moral to draw from the study—apart from try to marry a happy person—since the stress of trying to figure out how to improve your spouse’s mood may well undo all the beneficial effects of having a happy spouse. Chopik has a workaround. “Relationship satisfaction between couples is one of the largest predictors of happiness,” he says. So instead of trying to figure out what’s up with him or her, he suggests working out what’s up with the two of you. 
  
 The study looked at four health indices: self-reported health, physical impairment, exercise and chronic conditions. The only thing that wasn’t improved by a cheerful life partner was the chronic conditions. Hey, love can’t fix everything.

 A happy spouse may be good for your health. 
  
 Previous studies have found that mental well-being — feeling happy and satisfied — is closely linked to good physical health. 
  
 But a new study, published in Health Psychology, suggests that physical health may also be linked to the happiness of one’s husband or wife. 
  
 Researchers used data from a survey of 1,981 heterosexual couples, a nationwide sample of Americans older than 50 whose happiness had been assessed periodically since 1992 using well-validated scales. They also completed regular questionnaires on physical health. 
  
 A person’s good health was independently associated with the happiness of his or her spouse. Consistently, people with an unhappy partner had more physical impairments, engaged in less exercise and rated their overall health worse than those who had a happy partner. 
  
 The lead author, William J. Chopik, an assistant professor of psychology at Michigan State University, said that a happy spouse provided social support and encouraged you to eat a healthful diet and to get exercise, all of which can contribute to good health. 
  
 “This speaks to the power of our close relationships,” Dr. Chopik continued. “We’ve known for a long time that when we surround ourselves with happy people, we’re happier.

If you follow the ping-ponging research, you'll know that happiness is achieved by staying single. Or maybe by expressing gratitude to your spouse. Or by having at least four kids. Well, it's time to add another line item to the list: Marry a happy person. So report researchers in the journal Health Psychology after analyzing data from a survey of nearly 2,000 heterosexual American couples over the age of 50 who regularly completed questionnaires on their health. But the study takes things a step further. It turns out that happy partners don't just rub off on their spouse's mood, but on their physical health: Those whose partners are happy were found to be 34% more likely to be healthy themselves. People with unhappy partners are more likely to report worse overall health, less exercise, and more physical impairments than those with happy partners, reports the New York Times. "This speaks to the power of our close relationships," the lead author says. The team proposes three central causes, reports Time: a happy spouse is more likely to have the energy to be a more proactive caregiver and partner; a happy spouse is more likely to engage in and thus reinforce healthy patterns such as regular exercise and sleep; and a happy spouse is less likely to cause their partner the stress and exhaustion of trying to cheer up or avoid upsetting them. (Unhealthy people appear to affect their partners' health, too.)
