The Science of Awe: How Everyday Wonder Rewires the Brain and Body

You know the feeling: standing beneath a canopy of towering ancient trees, watching a thunderstorm roll across the horizon, or hearing a piece of music that stops you mid-thought. It is an expansive, quieting sensation where everyday worries momentarily fall away. For centuries, this emotion—awe—was considered the exclusive domain of poets, philosophers, and mystics. It was viewed as a fleeting, poetic luxury rather than a biological necessity.[6]

Today, however, awe has become a subject of rigorous scientific inquiry. Over the past two decades, psychologists and neuroscientists have pulled awe out of the realm of the abstract and into the laboratory. What they are discovering is fundamentally shifting our understanding of human well-being. Awe is not just a pleasant feeling; it is a distinct, measurable emotion that triggers profound physiological and psychological changes.[1][6]

The modern scientific study of awe largely began in 2003, when psychologists Dacher Keltner and Jonathan Haidt published a landmark paper defining the emotion. They proposed that awe is triggered by two core phenomena: "perceived vastness" and a "need for accommodation." Vastness can be physical, like looking at the Milky Way, or conceptual, like grasping a complex scientific theory. The need for accommodation occurs when this vastness forces the brain to expand its existing mental models to make sense of what it is experiencing.[1]

When the brain encounters this vastness, remarkable neurological shifts occur. Functional MRI scans reveal that experiencing awe deactivates the Default Mode Network (DMN). The DMN is a network of interacting brain regions that is highly active when we are engaged in self-reflection, rumination, or ego-driven thoughts. It is the neurological home of the "inner critic." When awe strikes, the DMN quiets down, effectively muting anxiety and self-centered worry.[3][5]

Researchers refer to this psychological shift as the "small self." When we are in the presence of something vast, our sense of ego temporarily shrinks. Our personal concerns, which often feel overwhelming in isolation, are suddenly placed in a much larger context. This diminishment of the ego does not lead to feelings of insignificance or depression; rather, it fosters a profound sense of relief and deep connection to the world around us.[1][5]

The benefits of awe extend far beyond the brain, cascading through the entire nervous system. Experiencing awe activates the vagus nerve, a critical component of the parasympathetic nervous system responsible for the body's "rest and digest" functions. This activation slows the heart rate, deepens breathing, and moves the body out of the chronic "fight or flight" state that characterizes modern stress.[3][6]

Perhaps the most striking physiological discovery involves inflammation. In a 2015 study, researchers found that among various positive emotions—including joy, amusement, and pride—awe was the strongest predictor of lower levels of interleukin-6 (IL-6). IL-6 is a pro-inflammatory cytokine; chronically high levels are linked to stress, depression, and autoimmune diseases. Regular doses of awe appear to act as a natural anti-inflammatory for the body.[3][5]

To test whether awe could be prescribed as a behavioral intervention, researchers at the UCSF Memory and Aging Center partnered with UC Berkeley to conduct a randomized controlled trial. They recruited 60 older adults and asked them to take a 15-minute outdoor walk once a week for eight weeks. The participants were split into two groups: a control group and an "awe walk" group.[2]

The control group was simply told to walk outdoors. The awe group, however, was given specific instructions: they were asked to tap into a childlike sense of wonder, to intentionally look for vastness, and to notice the unexpected details in their environment. They were taught that with the right outlook, awe could be found anywhere, from a towering skyscraper to the intricate veins of a single leaf.[2][4]

The results were striking. Over the eight weeks, the awe walkers reported significant increases in daily joy and prosocial emotions like compassion and gratitude. More importantly, they experienced a measurable decrease in daily distress compared to the control group. Even though the control group actually walked more frequently, they did not experience the same emotional benefits, proving that the mindset of the walk mattered more than the physical exercise alone.[2][4]

The most fascinating evidence from the UCSF study came from photographs. Participants were asked to take a selfie during each of their weekly walks. As the weeks progressed, the researchers noticed a distinct visual shift in the photos taken by the awe group. The participants literally began to take up less space in their own selfies, shifting the camera to focus more on the landscapes and environments around them. It was visual proof of the "small self" in action.[2][4]

A common misconception is that awe requires a trip to the Grand Canyon or a total solar eclipse. However, researchers emphasize the concept of "everyday awe." A 2023 diary study tracking adults for three weeks found that people experience awe surprisingly often—about every third day—if they are open to it. On days when participants experienced awe, they reported 20 percent less stress and fewer physical complaints.[3][6]

In his extensive research, Dacher Keltner identified eight universal sources of awe, which he calls the "Eight Wonders of Life." These include nature, music, visual design, spiritual experiences, big ideas, the cycle of life and death, and collective movement (such as dancing in a crowd). Understanding this taxonomy helps people realize how accessible awe truly is in daily life.[1][6]

Surprisingly, the most common source of awe globally is not nature, but what Keltner terms "moral beauty." When researchers surveyed thousands of people across different cultures, the most frequent trigger for awe was witnessing the courage, kindness, or strength of other people. Seeing a stranger help someone carry groceries or hearing a story of profound resilience triggers the release of oxytocin and anchors us in awe.[1][4]

Another powerful source is "collective effervescence," a term coined by sociologist Émile Durkheim. This is the shared awe that blooms in groups—when voices rise together in a choir, when a stadium erupts in unison, or when a crowd falls into step during a march. This shared vastness dissolves the boundaries between individuals, fostering a deep sense of belonging.[3][6]

From an evolutionary perspective, this makes perfect sense. Why would humans evolve to feel an emotion that makes us feel small? Evolutionary biologists argue that awe is a survival mechanism. By shrinking the ego and promoting a sense of interconnectedness, awe drives prosocial behaviors. It makes us more likely to cooperate, share resources, and sacrifice for the group—traits that were essential for the survival of early human communities.[1][5]

The challenge today is that modern society is increasingly awe-deprived. We spend the vast majority of our time indoors, our attention fractured by smartphones and doomscrolling. The cultural focus on individualism and relentless productivity actively works against the ego-dissolving, time-expanding nature of awe. We are biologically wired for wonder, but we have engineered environments that starve us of it.[3][6]

Fortunately, the antidote is entirely within our control. Cultivating awe does not require money, travel, or vast amounts of time. It requires only a shift in attention. By creating micro-rituals—pausing to watch the clouds shift, listening deeply to a complex piece of music, or taking a 15-minute awe walk—we can actively engage this powerful biological mechanism. Awe is not just a decoration for a good life; it is the structural scaffolding of a resilient mind.[4][6]
