If you’ve noticed some of your habits changing after marriage, there might be science behind it. In fact, being coupled up may alter your drinking behavior, in particular, suggests a new study from the University of Virginia published in The Journal of Family Psychology. According to the study, those who are married or cohabitating tend to drink less than people who are single or divorced.

For the study, lead author Diana Dinescu, a University of Virginia Ph.D. candidate in clinical psychology, used data from the Washington State Twin Registry to study 1,618 female twins and 807 male twins. Using the data from the twin pairs, Dinescu compared drinking patterns and quantity in married couples versus single people. The data showed that cohabitating and married twins consumed less alcohol than single or divorced twins.

"It seems that intimate relationships may provide a real benefit in terms of drinking behavior, maybe through mechanisms such as a monitoring effect that partners have on each other,” Dinescu said in a statement.

Whether these findings ring true for you or not, other studies indicate that couples who have similar drinking habits are more likely to stay together.
