If you want to reignite the passion in your relationship this Valentine’s Day, skip the intimate, candle-light dinner for two and go on a double date.

That’s the conclusion out of a new US study, which found that striking a friendship with another couple can help people view their partners and their relationship in a new light.

Though researchers from Wayne State University in Detroit had hypothesized that couples who spend time with other couples would add another level of excitement to relationships, they note that the impact was more significant or ‘robust’ than they originally thought.

For their study, researchers enlisted 150 couples who were paired up and asked to answer a set of questions categorized as either small talk or deeper, personal questions dubbed “high-disclosure Fast Friends” such as “What was the most embarrassing moment in your life?”

Couples tasked with the high-disclosure activity reported feeling higher levels of “passionate love” following their meeting, compared to those assigned to engage in small talk.

Furthermore, when couples were more responsive with their new friends -- defined as validating the sharing of personal information in a caring and positive way -- they felt more passionate about their own relationship, researchers noted.

To set the mood this Valentine’s Day, researchers suggest hosting a double-date dinner at home or a quiet restaurant, a setting conducive to speaking freely and sharing personal information.

The findings were presented at the annual conference in Austin this week.
