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.
