by Psychologists studying relationship longevity point to a consistent pattern: trying new activities together predicts renewed relational and physical attraction
Psychological research examining what sustains attraction in long-term relationships has consistently identified one factor as a reliable predictor of renewed romantic and physical interest between established partners: shared novelty, the experience of trying new activities together, rather than any single technique or gesture aimed directly at romance or physical intimacy itself.
This line of research draws on what psychologists call self-expansion theory, the idea that romantic relationships derive much of their vitality from partners’ shared sense of personal growth and expanding experience together. According to this framework, the excitement and attraction couples often experience early in a relationship stems significantly from the rapid pace of shared new experiences characteristic of early dating, rather than purely from novelty of the partner themselves.
Why Long-Term Couples Often Experience Declining Novelty
As relationships mature, couples naturally settle into established routines, a pattern that offers genuine benefits including stability and predictability, but that also, according to self-expansion theory, reduces the rate of shared new experience that originally contributed to early-relationship excitement and attraction. Researchers argue this natural settling process, rather than any deficiency in the partnership itself, explains much of the commonly reported decline in relational excitement many long-term couples describe.
What the Research Shows About Reintroducing Novelty
Studies examining couples who deliberately introduce new shared activities into their relationship, learning a new skill together, traveling somewhere unfamiliar, trying an unfamiliar physical activity, consistently find measurable increases in reported relationship satisfaction and attraction following these novel shared experiences, an effect that appears to operate largely independent of the specific activity chosen, suggesting the novelty itself, rather than any particular activity’s content, drives the observed effect.
Why This Works, According to Psychological Theory
Researchers propose that shared novel experiences work by reactivating the same psychological processes of mutual discovery and expanding self-concept that characterized the relationship’s early stages, allowing partners to see each other in new contexts and roles rather than exclusively through the lens of established routine. This mechanism, researchers argue, explains why the specific novel activity matters less than the simple fact of genuine shared unfamiliarity and mutual discovery.
Practical Applications for Couples
Relationship therapists increasingly incorporate this research directly into practice, encouraging long-term couples experiencing declining relational excitement to deliberately schedule shared novel experiences, rather than assuming renewed attraction requires either resolving a deeper underlying problem or accepting decline as an inevitable feature of relationship longevity. This reframing, therapists say, offers a genuinely actionable, evidence-based intervention that couples can implement directly without necessarily requiring extensive therapeutic intervention first.
A Consistent Finding Across Different Study Designs
This pattern has been replicated across multiple different research methodologies, including laboratory studies where couples completed novel tasks together under controlled conditions, and longitudinal field studies tracking couples’ real-world shared activities and corresponding relationship satisfaction over extended periods, lending considerable confidence that the effect reflects a genuine, robust psychological phenomenon rather than a finding specific to any single study’s particular conditions or population.
What This Means for How Couples Think About Long-Term Relationship Maintenance
Researchers argue this body of work offers a genuinely hopeful message for long-term couples: declining excitement and attraction, while common, is not necessarily a fixed or inevitable feature of relationship longevity, but rather appears connected to a specific, identifiable, and addressable factor, the rate of shared novel experience, that couples retain meaningful ability to actively influence through deliberate choices about how they spend time together. “Couples sometimes treat declining spark as a verdict on the relationship itself,” one researcher in the field said. “This research suggests it’s often more accurately understood as a symptom of routine, something couples have real, practical power to address, rather than a permanent diagnosis they simply have to accept.”
How Much Novelty Is Actually Necessary
Researchers caution that the required dose of novelty appears modest rather than dramatic, undermining any assumption that couples need elaborate, expensive, or infrequent experiences like major travel to produce the effect. Smaller-scale novel experiences, trying an unfamiliar restaurant, taking a single class together, exploring an unvisited part of one’s own city, appear to produce measurable benefits comparable to larger undertakings, provided the experience genuinely involves shared unfamiliarity for both partners rather than one partner’s established comfort zone or existing hobby.
This finding matters practically, researchers note, because it removes a common barrier couples cite for not pursuing novelty more regularly: the assumption that meaningful novelty requires significant time, money, or logistical planning that busy schedules or tight budgets simply don’t accommodate. “You don’t need a trip to another country,” one relationship researcher explained. “You need something genuinely new to both of you, even if it’s small and close to home. The psychological mechanism doesn’t appear to care much about scale. It cares about genuine shared unfamiliarity.”
For couples navigating the demands of careers, children, and established routines, this lower bar for meaningful novelty offers a genuinely practical starting point rather than an aspirational ideal reserved for rare, well-resourced occasions. Researchers say the consistent replication of this finding across study designs gives them confidence recommending it as a legitimate, evidence-based relationship maintenance strategy, one couples can begin implementing immediately without waiting for a major life event or milestone to justify the effort.
