Psychologist Stephanie Wilson and her team\u00a0followed 107 married or cohabiting couples, ages 40 to 87. Researchers collected blood samples to measure a range of biological aging markers. These included how quickly a person\u2019s cells wear down over time, inflammation-related damage, and other indicators of physical wear and tear.\u00a0\u00a0<\/p>\n\n\n\n
The group also conducted surveys about each couple\u2019s relationship. They asked for details ranging from how often they shared good news to how they dealt with unresolved arguments. The team also tracked each subject\u2019s sleep, diet, and exercise routines. <\/p>\n\n\n\n The finding: happier couples showed signs of slower cellular aging, as expected, but only among couples who also exercised regularly, slept well, and ate a healthy diet.\u00a0When those habits were poor, the benefit of their happy partnership faded.\u00a0In some cases, a joyful marriage paired with poor sleep and diet was linked to faster telomere shortening (the protective caps on our chromosomes).<\/p>\n\n\n\n Wilson\u2019s team\u00a0started with a simple idea: the behaviors that bring us closer aren\u2019t always the ones that benefit our bodies and long-term health. Think of a cozy night binge-watching TV with the one you love over a pint of ice cream or cocktails. Yes, it is bonding, and sure, it\u2019s a lot of fun in the moment. But things get stickier when it becomes a recurring part of a couple\u2019s routine.<\/p>\n\n\n\n Researchers refer to this as a \u201cvicious cycle.\u201d It\u2019s a habit that reinforces sedentary behaviors, like regularly ordering takeout high in saturated fat and staying up too late. This can also work in reverse. Love can fuel a virtuous cycle, where partners keep each other going with cardio-enhancing evening walks and well-balanced, home-cooked dinners.<\/p>\n\n\n\n The same kind of love, but different habits, led to different health outcomes.<\/p>\n\n\n\n Of course, there are some important caveats. The couples in the study were mostly white, highly educated, and healthier than average. Additionally, people with many serious chronic illnesses were left out of the sample group. The study does show health associations related to a couple\u2019s habits. It did not conclusively prove that a marriage directly speeds up or slows down aging. The researchers emphasized that these results are preliminary and will need to be repeated with larger, more diverse groups.<\/p>\n\n\n\n And no, the takeaway isn\u2019t to love each other less. The paper points out that couples can be very happy no matter how healthy or unhealthy their habits are. The conclusion advises investing in both a healthy relationship and a healthy lifestyle. <\/p>\n\n\n\n A great date night can be dinner and a movie. It can also include a nice walk after that meal. Try cooking at home together more often, and aim for balanced meals with lean proteins and plenty of fibrous veggies. Make a pact to both turn off your screens at least an hour before bed. It\u2019s about the small things done as a team, because the healthiest love story is the one where you both get to stick around to tell it.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" When it comes to living longer, marital bliss is only half the solution.
