Research Reveals Five Key Benefits of Expressing Gratitude

Research led by Christopher Oveis, an associate professor at the University of California San Diego, highlights the significant benefits of expressing gratitude. His findings reveal that saying “thank you” can strengthen relationships, reduce stress, and enhance bodily performance under pressure. Oveis, who studies the impact of positive emotions, emphasizes the mutual benefits of gratitude for both the giver and receiver.

Oveis states, “Gratitude is powerful because it benefits everyone involved—the person who expresses it, the person who receives it, and even those who witness it.” He encourages individuals to express their gratitude openly, explaining that even small gestures can have profound effects.

1. Enhanced Performance Under Pressure

In a study inspired by the television show *Shark Tank*, Oveis and his team enlisted UC San Diego students to collaborate in high-pressure scenarios. Participants were tasked with pitching a new bicycle design to a panel of judges. Some teams took a moment to express gratitude among teammates before the challenge. The results were remarkable: those who engaged in gratitude exhibited healthier cardiovascular responses, suggesting a physiological readiness to tackle stress.

“People who feel appreciated are more prepared to perform well,” Oveis explains. “Their bodies respond better to stress.”

2. Strengthening Relationships

Gratitude extends beyond close friends and family; it plays a crucial role in everyday interactions. Oveis notes that gratitude fosters connections among coworkers, classmates, and community members. He asserts that it communicates recognition and appreciation, fostering trust and cooperation.

His research shows that even brief expressions of thanks between near-strangers can create a sense of connection and improve collaborative efforts. Over time, these small acts contribute to stronger, more supportive relationships.

3. Boosting Team Performance

When team members express gratitude, it fundamentally changes their collaborative dynamics. Oveis found that teammates who thanked one another before engaging in stressful tasks performed better and felt more empowered to meet challenges. Gratitude signals a supportive environment, fostering resilience in any setting, whether in a classroom, workplace, or household.

“When you are heading into a significant meeting or presentation and know that your team has your back, it greatly influences your performance,” Oveis adds.

4. The Contagious Nature of Gratitude

The benefits of gratitude extend beyond the individuals directly involved. Oveis’s research indicates that observers of gratitude—those who witness expressions of thanks—also experience positive effects. Witnessing gratitude fosters feelings of connection and encourages cooperative behavior. Oveis states, “Observers want to be around people who express gratitude. They’re more likely to want to help, collaborate, and share. Gratitude spreads.”

This ripple effect is particularly influential among leaders. Oveis encourages leaders to express gratitude openly, noting that it positively impacts both their own well-being and that of their teams.

5. Focusing on the Other Person

Not all expressions of gratitude carry the same weight. Oveis refers to research by his collaborator, Sara Algoe, from the University of North Carolina at Chapel Hill. The most effective gratitude expressions are those that focus on the recipient’s actions and thoughtfulness.

Oveis explains, “When your thank you centers on the other person—like, ‘You really went out of your way to help me’—it strengthens the bond.” In contrast, focusing solely on personal needs diminishes the impact of the gratitude expressed.

As individuals prepare for gatherings, such as Thanksgiving, Oveis suggests taking moments to authentically express gratitude. “It’s not about going around saying thank you just to check a box,” he warns. “People can tell when it’s not genuine.”

He encourages everyone to reflect on what they are grateful for and communicate it to those around them. “Taking a moment to reflect on what you’re grateful for is good for you, but actually saying it to the people around you—that’s what strengthens relationships.”

Oveis succinctly summarizes his message: “If you feel gratitude, let it out. Don’t hold it in.” This simple practice can create significant ripple effects, enhancing connections and improving overall well-being.
