Gratitude Beyond Thanksgiving
What New Science Reveals About One of the Most Transformative Human Emotions
Every November, we return to gratitude as if it belongs to a single holiday — a pause between travel, prepping for the meal, and the swirl of family rituals and obligations. But gratitude is not a performance. It’s a practice. And according to the latest research, it may be one of the most profound and accessible tools we have for resilience, emotional steadiness, and even longevity.
Across psychology, neuroscience, and public health, researchers are finding that gratitude doesn’t simply make us feel good. It reorganizes attention. It regulates emotion. It strengthens memory and deepens connection. It helps us see our lives more clearly — especially in the moments that feel the most uncertain.
Gratitude isn’t an overly precious pause from the world; it’s how we stay grounded in it a day at a time.
I first wrote at length about gratitude for the Los Angeles Times, and the science has since expanded. Here’s what the new research shows — and why gratitude is having a renaissance.
1. Gratitude may help us live longer
A 2024 Harvard T.H. Chan School of Public Health study found that experiencing gratitude may help older adults live longer. Researchers following more than 49,000 older women found that those with the highest levels of gratitude had a 9% lower risk of all-cause mortality over four years, even after adjusting for mental health, health behaviors, and social factors.
It’s early evidence, but compelling: how we make sense of our lives may influence how long we get to live them.
2. It regulates stress — chemically and emotionally
The University of Rochester Medical Center (2024) notes that focusing on what you’re grateful for is associated with lower cortisol, increases in the feel-good chemicals dopamine and serotonin, and more stable mood regulation.
This aligns with decades of work by researchers, including Northwestern University professor and social psychologist Judith Moskowitz and UNC professor Dr. Barbara Fredrickson, known for her “Broaden-and-Build Theory” of positive emotion, who have shown how gratitude widens our emotional bandwidth and helps us recover more quickly from stress.
3. It meaningfully improves sleep
Research shows that people who regularly practice gratitude tend to sleep longer and more restoratively. Even modest improvements in nightly sleep were linked with better mood, higher life satisfaction, and more prosocial behavior the next day.
When falling asleep, grateful people were found to be less likely “to think negative and worrying thoughts, and more likely to think positive thoughts.”
4. It can interrupt damaging comparison and strengthen attention
Social media can intensify feelings of scarcity and endless comparisons, leaving you feeling like you’re on the short end of someone else’s fabulous life.
Gratitude, however, can shift the attentional lens toward what is already enough and recalibrate the brain’s attentional networks. This helps reduce rumination and makes it easier to disengage from comparison cycles.
Here is a terrific clip about the power of gratitude from Harvard Kennedy School Professor and best-selling author Dr. Arthur Brooks.
5. It deepens connection, the cornerstone of human thriving
The Harvard Study of Adult Development, the world’s longest study of well-being (read more about my interview with study director Dr. Robert Waldinger), continues to emphasize that strong relationships are the greatest predictor of long-term happiness.
Gratitude strengthens those relationships. Indeed, gratitude can help with a wealth of well-being practices, including building trust, increasing empathy, and recognizing the network support that makes life meaningful. Acknowledging even small moments of care strengthens the fabric of a relationship.
6. It protects mental health
For decades, practicing gratitude has been linked to greater well-being, including lower depression, greater optimism, and an increased sense of purpose.
Newer findings support this: gratitude’s influence on stress physiology, mood-related neurotransmitters, and attentional patterns, all of which contribute to emotional resilience.
7. It strengthens identity and meaning
Gratitude reinforces the memory of support — the people, places, and experiences that have shaped us. It offers a more coherent, compassionate sense of self. An important element of well-being, as emphasized by research on emotion and social interaction, positive psychology, human cognition, and by scholars of awe and happinesss, including Dacher Keltner and Yale’s Dr. Laurie Santos of The Happiness Lab.
8. It supports healthier communities
Gratitude has a ripple effect.
When people feel grateful, they tend to act more generously — donating more, volunteering more, and offering emotional support more freely.
Research shows that gratitude predicts stronger community bonds and more prosocial behavior.
9. It helps kids and teens thrive
The benefits of gratitude start early. Young people who practice gratitude experience more positive emotion, healthier friendships, less envy, and greater life satisfaction. These benefits carry into adulthood.
10. Gratitude strengthens agency
Gratitude doesn’t erase hardship but it can offer perspective. It helps us notice what sustains us so we can act from clarity rather than fear — something Kristi Nelson of Grateful.org describes as “It’s really powerful to steep ourselves in what we’re grateful for and then act to defend, protect and advance that in the world.”
