Long-married couples often schedule a weekly “date night” — a regular evening out with friends or at a favorite restaurant to strengthen their marital bond.

But brain and behavior researchers say many couples are going about date night all wrong. Simply spending quality time together is probably not enough to prevent a relationship from getting stale.

Using laboratory studies, real-world experiments and even brain-scan data, scientists can now offer long-married couples a simple prescription for rekindling the romantic love that brought them together in the first place. The solution? Reinventing date night.

Rather than visiting the same familiar haunts and dining with the same old friends, couples need to tailor their date nights around new and different activities that they both enjoy, says Arthur Aron, a professor of social psychology at the State University of New York at Stony Brook. The goal is to find ways to keep injecting novelty into the relationship. The activity can be as simple as trying a new restaurant or something a little more unusual or thrilling — like taking an art class or going to an amusement park.
