How Awe Boosts Your Immune System: The Science of Wonder

By 2030, the most prescribed medicine may not come from a pharmacy—it might come from a 15-minute walk outside your door. Scientists are uncovering a profound connection between a simple emotion—awe—and our body's frontline defense system. While we've long known that stress weakens immunity and joy helps us heal, researchers now understand that awe—that spine-tingling feeling when you witness something vast and extraordinary—triggers a cascade of neurological and hormonal changes that can measurably boost immune function, reduce inflammation, and potentially add years to your life.

The Breakthrough That Changes Everything

In 2024, the FDA began reviewing a remarkable device that stimulates the vagus nerve to treat autoimmune diseases like rheumatoid arthritis. In a study of 242 patients, 12 weeks of vagus nerve stimulation didn't just reduce symptoms—it slowed joint damage and dramatically lowered inflammatory proteins throughout the body. The vagus nerve, it turns out, acts like brake lines in a car, signaling the immune system to dial down its attack.

What's revolutionary is this: you don't need a medical device to activate this neural pathway. Experiencing awe—whether from watching a sunset, listening to music that gives you chills, or witnessing an act of extraordinary kindness—naturally stimulates the same vagus nerve, triggering similar anti-inflammatory effects.

Dr. Dacher Keltner, a psychologist at UC Berkeley who has spent 15 years studying awe, conducted a randomized trial with 60 older adults. Those who took weekly "awe walks" for eight weeks reported increased joy, bigger smiles, heightened prosocial emotions, and decreased daily distress compared to a control group. But the effects ran deeper than mood: participants' selfie photos showed progressively wider smiles and broader visual perspectives, suggesting fundamental shifts in how they saw themselves in relation to the world.

From Ancient Survival to Modern Medicine

Awe didn't evolve for Instagram moments. Anthropologists and evolutionary psychologists believe this emotion developed to serve critical social functions in early human communities. When our ancestors encountered something vast—a powerful leader, a dangerous storm, an immense landscape—awe created what researchers call "cognitive accommodation," forcing the brain to update its mental models of reality.

Keltner and psychologist Jonathan Haidt proposed in their seminal 2003 paper that awe originally reinforced social hierarchies, helping low-status individuals recognize and respond appropriately to high-status or powerful others. This emotional response would have been adaptive, promoting social cohesion and reducing conflicts that could threaten group survival.

But awe also encouraged learning and exploration. When early humans encountered the vastness of nature or witnessed incredible human achievements, the resulting sense of wonder motivated them to understand, adapt, and innovate. Groups that cultivated shared experiences of awe—through rituals, storytelling, or communal encounters with nature—developed stronger bonds and more effective cooperation strategies.

This evolutionary heritage explains why awe experiences still powerfully affect us today, but in ways our ancestors never imagined: by directly modulating our immune responses.

How Awe Rewires Your Brain

When you experience awe, your brain undergoes a remarkable transformation. Multiple neural networks activate simultaneously, creating a unique neurological signature that distinguishes awe from other positive emotions like happiness or contentment.

The default mode network (DMN)—brain regions including the medial prefrontal cortex, posterior cingulate cortex, and precuneus—typically buzzes with activity during self-referential thinking, the mental chatter of "me, myself, and I." During awe experiences, this network quiets dramatically. This "small self" effect explains why time seems to expand during moments of wonder: you're literally getting out of your own head.

Simultaneously, the prefrontal cortex, particularly the ventromedial region, ramps up activity. This area integrates new information, helping you make sense of experiences that don't fit existing mental frameworks. When you encounter something vast that demands cognitive accommodation—a breathtaking landscape, a profound idea, an act of moral beauty—your prefrontal cortex works to expand your understanding of what's possible.

The amygdala and insula also activate during awe. The amygdala processes emotional significance, while the insula contributes to interoception—your awareness of internal bodily states. This explains the physical sensations of awe: the goosebumps, the catch in your breath, the warmth spreading through your chest. These aren't just poetic descriptions; they're measurable physiological responses.

In a 2025 pilot study using fMRI scans, researchers at UCLA showed participants AI-generated nature scenes and cosmic imagery designed to elicit awe. The scans revealed heightened activation in the fusiform gyri, postcentral gyri, and hippocampus—regions involved in visual processing and memory formation. Crucially, the researchers also observed reduced activity in areas linked to stress, anxiety, and executive control. Nature wasn't just capturing attention; it was actively calming the neural circuits associated with chronic stress.

This neural quieting represents what neuroscientists call "transient hypofrontality"—a temporary relaxation of prefrontal cortex dominance that also occurs during meditation, creative flow states, and profound wonder. It's the brain's reset button, allowing rigid patterns of thought to soften and new perspectives to emerge.

The Neurochemical Bridge to Immunity

The brain changes during awe trigger a cascade of neurochemical releases that directly influence immune function. Two molecules stand at the center of this mind-body connection: dopamine and oxytocin.

When you encounter something novel and significant, the ventral tegmental area floods your brain with dopamine. This isn't merely a reward signal; it's an alarm that says, "Pay attention—this matters!" Dopamine sharpens focus, enhances learning, and creates the pleasurable sense of fascination that makes awe experiences so compelling. Importantly, dopamine also influences immune cell activity, modulating their responsiveness to threats.

Oxytocin, often called the "love hormone," plays an even more intriguing role. Produced in the hypothalamus and released by the posterior pituitary, oxytocin has long been associated with social bonding, trust, and empathy. But researchers at Duke University discovered that oxytocin also enhances the experience of awe itself.

In their study, participants who received oxytocin before guided meditation reported significantly higher ratings of awe, gratitude, hope, inspiration, interest, love, and serenity compared to those who received a placebo. More remarkably, those who received oxytocin were more inclined to view themselves as interconnected with other people and living things, endorsing statements like "All life is interconnected" and "There is a higher plane of consciousness that binds all people."

The study's lead author, Patty Van Cappellen, noted: "Oxytocin appears to be part of the way our bodies support spiritual beliefs." But the implications extend beyond spirituality. Oxytocin activates the vagus nerve, a major highway of the parasympathetic nervous system that runs from the brainstem to the abdomen, touching virtually every major organ along the way.

When the vagus nerve fires, it triggers the body's "rest and digest" mode, the opposite of the "fight or flight" stress response. Heart rate slows, breathing deepens, digestion improves—and critically, inflammation decreases. The vagus nerve signals the spleen to reduce production of pro-inflammatory cytokines, the chemical messengers that, in excess, contribute to chronic diseases ranging from arthritis to cardiovascular disease to depression.

Dr. Kevin Tracey, who pioneered research on this "inflammatory reflex," discovered that the vagus nerve signal travels directly to immune organs. "We realized that the signal was traveling down the vagus nerve," Tracey explained, "and the vagus nerve was like the brake lines in your car." When you experience awe, you're essentially pressing the brake pedal on runaway inflammation.

The Immune System Evidence

The biological plausibility of awe's immune effects is one thing; demonstrable evidence is another. Multiple lines of research now support the connection.

Studies have found that awe experiences correlate with decreased levels of pro-inflammatory cytokines, particularly interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). These molecules are central players in chronic inflammation, the slow-burning fire that underlies diseases from Type 2 diabetes to Alzheimer's. When cytokine levels remain elevated over time, they damage tissues, accelerate aging, and suppress immune surveillance—the body's ability to detect and eliminate cancerous cells.

Researcher Ming Kuo, after reviewing hundreds of studies examining nature's effects on health, concluded that the immune system may be the primary pathway through which nature exposure protects against "a startling range of diseases, including depression, diabetes, obesity, ADHD, cardiovascular disease, cancer, and many more." While correlation doesn't prove causation, Kuo's analysis identified immune enhancement as the most consistent mechanistic thread.

Nature provides what Kuo calls a "multivitamin" of beneficial compounds: phytoncides (antimicrobial compounds released by trees), Mycobacterium vaccae (a soil bacterium that may boost serotonin), negative air ions, vitamin D from sunlight, and the psychological restoration that comes from engaging with living systems. But Kuo argues that the emotional experience of awe may be what ties these benefits together, creating the autonomic shift—from sympathetic to parasympathetic dominance—that allows the immune system to recalibrate.

Direct evidence comes from intervention studies. Research shows that feelings of awe can lower cortisol, the primary stress hormone. Chronically elevated cortisol suppresses immune function, reduces the activity of natural killer cells (which target viruses and tumors), and impairs the production of antibodies. By reducing cortisol, awe removes a major brake on immune effectiveness.

In one striking study, older adults who participated in daily awe walks exhibited not only increased joy and decreased distress but also biological markers suggesting improved stress regulation. While this study didn't directly measure immune cell counts or antibody levels, the cortisol reductions it documented have well-established downstream effects on immune competence.

Perhaps most intriguingly, patients with depression who received ketamine infusions—a treatment that rapidly reduces depressive symptoms—reported heightened feelings of awe that persisted for up to 30 days. Depression is strongly associated with elevated inflammatory markers, and ketamine is known to reduce inflammation. The co-occurrence of increased awe and decreased inflammation raises the possibility that awe itself may be part of the therapeutic mechanism.

What Makes Awe Different from Other Positive Emotions

Joy makes you smile. Gratitude makes you appreciative. Love makes you feel connected. But awe does something none of these other emotions can: it fundamentally alters your sense of self in relation to the world.

Researchers call this the "small self" effect. When you feel awe, your concerns, worries, and ego preoccupations shrink in perceived importance. You're no longer the center of your universe; you're a small part of something immeasurably larger. This cognitive shift has profound psychological and physiological consequences.

Studies consistently show that awe increases prosocial behavior—generosity, cooperation, ethical decision-making—more than other positive emotions. People who've just experienced awe are more likely to help strangers, more willing to donate time or money, and more inclined to make environmentally sustainable choices. This happens because awe temporarily dissolves the boundaries between self and other, making collective welfare feel personally relevant.

The neural basis of this distinction appears in brain imaging studies. While happiness and contentment activate reward circuits and pleasure centers, awe uniquely combines reduced default mode network activity (quieting self-focus) with increased prefrontal cortex engagement (expanding perspective) and amygdala activation (heightening emotional significance). No other emotion produces this exact constellation of neural changes.

This unique profile explains why awe experiences don't habituate the way pleasures do. When you eat your favorite food repeatedly, each bite brings less satisfaction—a phenomenon called hedonic adaptation. But research suggests that awe induces more awe. Regular awe-walkers report that their capacity for wonder increases over time, as if the experience opens and expands rather than satifies and closes. This creates a virtuous cycle: the more you practice noticing awe, the more readily you experience it, and the more biological benefits accumulate.

The Right Dose: How Much Awe Do You Need

One of the most encouraging findings from awe research is that a little goes a long way. You don't need to visit Machu Picchu or witness the Northern Lights to gain benefits. Brief, regular exposures to awe-inducing experiences can produce measurable improvements in wellbeing and biological markers of health.

The UC Berkeley awe walk study prescribed just 15 minutes once per week for eight weeks. That's two hours total—less time than a single movie—yet participants showed sustained improvements in emotional state and perspective. A survey of 2,600 people worldwide identified eight common sources of awe that don't require extraordinary circumstances: moral beauty (witnessing acts of courage or compassion), collective effervescence (synchronized group experiences), nature, music, visual art, spirituality or religion, big ideas, and stories of life or death.

Michael Amster and Jake Eagle developed what they call the A.W.E. Method, which requires just 15 seconds, three times per day. In studies with frontline healthcare workers during the COVID-19 pandemic, this ultra-brief practice proved so effective at reducing stress, anxiety, and depression that it qualified statistically as a medical intervention. The practice involves three simple steps: Attention (focus on something around you), Wait (pause and take a breath), Exhale and expand (notice how the object makes you feel and expand your awareness).

The key isn't duration or intensity—it's regularity and intention. Brief moments of integrated mindfulness can shift your autonomic nervous system from sympathetic to parasympathetic dominance within seconds, creating an emotional space conducive to awe. When this shift happens multiple times daily, it recalibrates your baseline stress response, making you more resilient and your immune system more responsive.

Individual Differences: Why Awe Affects People Differently

Not everyone experiences awe the same way or gains equal benefits. Research has identified several factors that influence awe responsiveness.

Personality traits: People high in openness to experience—those who enjoy novelty, complexity, and abstract ideas—report more frequent awe experiences and appear more affected by awe interventions. Extroverts, who seek out stimulating environments and social interactions, also tend to experience awe more readily than introverts.

Genetic variation: The Duke University oxytocin study found that the hormone's spiritual and awe-enhancing effects were stronger among individuals with a specific variant of the CD38 gene, which influences oxytocin receptor density in the brain. This suggests that some people may be biologically primed to experience awe more intensely or benefit more from its effects.

Cultural context: While facial expressions of awe show remarkable consistency across 26 countries (about 75% universal, according to research published in Nature), the situations that trigger awe vary by culture. In individualist societies like the United States, personal achievements and natural wonders often elicit awe. In collectivist cultures, communal rituals, demonstrations of social harmony, and acts that benefit the group may be more powerful awe triggers. This means that effective awe interventions may need cultural tailoring.

Prior trauma and mental health: Individuals with depression, anxiety, or post-traumatic stress disorder may find awe experiences initially challenging because reduced self-focus can feel threatening when the self has been under siege. However, controlled exposure to awe in therapeutic contexts—such as the rock climbing, skiing, and rafting that helped Iraq war veteran Stacy Bare overcome suicidal ideation—can be profoundly healing once safety is established.

Current stress levels: The same experience that evokes awe when you're relaxed might barely register when you're overwhelmed. This suggests that awe practices work best when integrated into a broader stress-management strategy, not used as a rescue intervention during acute crises.

Eight Practical Ways to Cultivate Daily Awe

1. Awe Walks in Your Neighborhood
You don't need wilderness access. The key is intention and perspective shift. Before walking, set an intention to notice vastness (the sky, patterns in nature, the complexity of human systems). Walk slowly, engage all senses, adopt a beginner's mind as if seeing everything for the first time, and conclude with gratitude. Research participants in the Sturm study reported that even familiar neighborhoods revealed wonders when approached this way.

2. Moral Beauty Practice
Watch short videos or read stories about people demonstrating courage, compassion, or selfless service—figures like Mahatma Gandhi, Mother Teresa, or everyday heroes in your community. Studies show that witnessing moral beauty triggers oxytocin release, which activates the vagus nerve and enhances feelings of interconnection. Keep a collection of inspiring stories you can turn to when you need a boost.

3. Musical Transcendence
Music that gives you chills—whether classical, jazz, gospel, or any genre—creates a reliable pathway to awe. The emotional intensity, complexity, and beauty of music can activate reward circuits while quieting self-referential thought. Create playlists specifically designed to evoke wonder, and listen with full attention rather than as background.

4. Art and Museums
Dr. Keltner notes that art activates dopamine release through novel representations of reality, and that public spaces with visually pleasing designs can trigger oxytocin, improving mood and prosocial behavior. You don't need major museums; local galleries, street art, and even architecture books can open portals to awe. Let yourself pause before works that challenge your perception or expand your sense of human possibility.

5. The 15-Second A.W.E. Method
Three times daily—morning, midday, evening—stop for 15 seconds. Focus attention on something present (a tree outside your window, the complexity of your hand, the sound of rain). Wait and breathe. Exhale and expand your awareness to include the vastness beyond the object. This micro-practice creates what Michael Amster calls "fast-acting" benefits that rival longer meditation sessions.

6. Stargazing and Cosmic Contemplation
On clear nights, spend time looking at stars. Use apps to identify constellations and planets, learning about the vast distances and timescales involved. Contemplate that the light entering your eyes left some stars thousands of years ago. This cosmic perspective reliably triggers the sense of vastness central to awe while connecting you to the same night sky humans have wondered at for millennia.

7. Collective Effervescence
Join group experiences where people move in synchrony or share intense emotional moments: concerts, religious services, dance classes, group sports, even walking together in silence. Research shows that collective awe can be stirred by just a handful of people and simple activities. The shared physiological synchronization—aligned breathing, heart rates, and movements—amplifies individual awe experiences.

8. Gratitude Journaling with Vastness
Traditional gratitude practices focus on personal benefits. Enhance them by connecting each point of gratitude to something vast: "I'm grateful for this meal, grown from seeds, soil, sun, and the 10,000-year history of agriculture." This links everyday positives to larger systems, triggering both gratitude and awe simultaneously.

The Complexity: What We Don't Yet Know

Despite growing evidence, significant gaps remain in our understanding of awe's immune effects.

Causation vs. correlation: Most studies show associations between awe experiences and improved health markers, but rigorous randomized controlled trials with long-term follow-up and direct immune measurements (antibody titers, natural killer cell activity, infection rates) are still limited. We don't yet know with certainty that awe directly causes immune enhancement rather than correlating with other health-promoting factors.

Optimal dosing: How much awe is enough? Is daily brief exposure superior to weekly longer experiences? Do intense rare moments (once-in-a-lifetime experiences) provide unique benefits that regular micro-doses cannot? These questions lack definitive answers.

Mechanism specificity: While the vagus nerve and oxytocin provide plausible pathways, we don't fully understand the step-by-step process from awe experience to immune cell behavior. What specific cytokine profiles change? How long do these changes persist? What cellular signaling cascades are involved?

Individual differences: Genetic, cultural, and psychological factors influence awe responsiveness, but we can't yet predict who will benefit most from awe interventions or tailor practices to maximize individual outcomes.

The dark side of awe: Awe can bridge divides and inspire cooperation, but it can also amplify tribalism and blind followers to moral atrocities. The same sense of vastness that opens hearts in one context can solidify group boundaries in another. As Keltner notes, the awe felt at Nazi rallies or by cult members shows that awe alone isn't inherently virtuous—context and values matter profoundly.

Long-term sustainability: Do awe interventions maintain their effectiveness over months and years, or do even wonder-enhancing practices eventually fall victim to habituation? Current studies follow participants for weeks to months, not years.

The Future of Awe Research

Scientists are exploring several promising directions that could transform how we understand and use awe in medicine.

Precision awe interventions: Researchers are working to identify which types of awe work best for specific conditions. Nature-based awe might optimize anti-inflammatory effects, while moral beauty might enhance social connection in isolated individuals. Personalized awe prescriptions could become as sophisticated as personalized medication protocols.

Technology-enhanced awe: Virtual reality offers controlled, repeatable awe experiences. Early studies suggest VR nature immersion produces similar neural and emotional effects as physical nature exposure, potentially democratizing access for people with mobility limitations or those living in environments with limited natural beauty.

Biomarker tracking: Wearable devices that monitor heart rate variability, cortisol levels, and other stress markers could provide real-time feedback during awe practices, helping people optimize their experiences and track cumulative benefits over time.

Integration with conventional medicine: Some healthcare systems are beginning to prescribe "social" interventions—nature exposure, art classes, group activities—alongside traditional treatments. As evidence grows, awe cultivation could become a standard complement to treatments for inflammatory diseases, depression, and chronic pain.

Neuroscience of awe development: Studies with children are beginning to map how awe capacity develops, which could inform educational practices and early interventions that build lifelong wonder-seeking habits.

Cultural neuroscience: Cross-cultural brain imaging studies could reveal whether different awe triggers produce identical neural signatures across populations or whether culture shapes the very neurobiology of wonder.

Preparing for a Wonder-Full Future

As evidence mounts that emotions directly influence physical health, we're witnessing a paradigm shift as significant as the germ theory of disease. The future may include "emotional fitness" programs as routine as physical fitness regimens, with awe cultivation as central as cardiovascular exercise.

To prepare for this future:

Develop your awe practice now: Don't wait for perfect conditions or extraordinary opportunities. Start noticing vastness in everyday moments. The skills of attention, openness, and perspective-taking improve with practice.

Protect awe-inducing environments: Natural spaces, dark skies for stargazing, public art, and cultural institutions that inspire wonder are public health infrastructure. Support their preservation and expansion.

Teach children to seek wonder: In a world of infinite digital distraction, cultivating the capacity for sustained attention to awe-inspiring experiences is a crucial life skill. Model curiosity, spend time outdoors, expose children to diverse forms of beauty and grandeur.

Create awe-rich communities: Design neighborhoods with visual beauty, access to nature, and spaces for collective experiences. Urban planning for wonder isn't frivolous—it's preventive medicine.

Advocate for research: Support funding for studies that can answer remaining questions about awe's mechanisms, optimal practices, and long-term health effects.

The simple feeling of awe—that spine-tingling moment when you confront something vast and extraordinary—may hold a secret that medicine has overlooked for too long. By understanding how wonder rewires your brain, recalibrates your stress response, and potentially supercharges your immune system, you gain access to a tool for health that requires no prescription, produces no side effects, and grows stronger with use. In a world that often feels small, divisive, and overwhelming, the capacity to experience awe isn't just pleasant—it might be essential for survival. The prescription is simple: look up, step outside, pay attention, and let yourself feel small in the face of something vast. Your immune system will thank you.
