Every summer, thousands and thousands of couples tie the knot.

Researchers have identified a variety of trends that show how getting married changes people. There has historically been an idea that marriage is good for your physical and mental health, perhaps due to the idea that having a supportive partner can make a person healthier. But more recent research has revealed that the relationship between marriage, health, and well-being is more complicated, with both benefits and drawbacks.

Evidence suggests that married men and women have a lower risk for certain types of heart disease than their single counterparts, for example, but married people are also more likely to be overweight.

Of course, these observed trends don't hold true for everyone. Every marriage is different, depending on the individuals involved, their relationship, their plans, lifestyles, and more - without even counting external factors. And there's much less research on the effects of marriage on same-sex couples so far.

But with that in mind, here are some of the ways that marriage tends to affect partners physically and mentally.

But a large study published last year found those health benefits were mostly observable in older married adults. Among younger adults, married people essentially saw no overall health benefit compared to their unmarried peers.

But these benefits and drawbacks shouldn't be a reason to get married or not.

Over time, our understanding of how marriage affects people has changed and become more refined. Some researchers think the reason single people's health appears to be better now than it used to when compared to married counterparts is that there's less societal stigma around single lifestyles these days.

But even if marriage is associated with certain health benefits, that alone isn't enough reason to partner up. Maintaining relationships has been shown to be a key part of lasting wellness, but there are many kinds of intimate partnerships.
