Abstract

How do experiences in nature or in spiritual contemplation or in being moved by music or with psychedelics promote mental and physical health? Our proposal in this article is awe. To make this argument, we first review recent advances in the scientific study of awe, an emotion often considered ineffable and beyond measurement. Awe engages five processes-shifts in neurophysiology, a diminished focus on the self, increased prosocial relationality, greater social integration, and a heightened sense of meaning-that benefit well-being. We then apply this model to illuminate how experiences of awe that arise in nature, spirituality, music, collective movement, and psychedelics strengthen the mind and body.

Research Summary of 'Awe as a Pathway to Mental and Physical Health'

Introduction

The paper opens from the observation that a range of transcendent experiences—contact with nature, spiritual practice, moving music, collective dance, and psychedelic experiences—are associated with improvements in mental and physical health, but the mechanisms linking these domains to health remain underdeveloped. Earlier research has shown broad links between positive affect and health, and subsequent work has examined specific positive emotions such as gratitude or compassion; however, the literature has paid relatively little attention to awe, an emotion often considered ineffable. The authors situate awe as a distinct emotional state that may explain how diverse sublime experiences ‘‘repair’’ or strengthen mind and body functioning. Monroy and colleagues set out to synthesise existing empirical and theoretical work on awe and to apply that synthesis to five domains that reliably elicit awe: nature, spiritual and mystical encounters, collective movement (music, dance, ceremony), and psychedelics. Their central proposal is that awe engages five processes—shifts in neurophysiology, diminished self-focus, increased prosocial relationality, greater social integration, and heightened meaning-making—that together form pathways by which awe can benefit mental and physical health. The review aims to integrate evidence across laboratory, daily-diary, computational, neuroscientific, qualitative, and clinical studies to support this model and to highlight directions for future research.

Methods

This article is a narrative synthesis and theoretical review rather than an empirical report of new data. Monroy and colleagues draw on a broad set of literatures—experimental inductions of awe, daily-diary and naturalistic studies, computational analyses of emotional responses to audiovisual stimuli, cross-cultural work, neurophysiology, and clinical research on psychedelics—to characterise awe and its downstream effects. The extracted text does not report a formal systematic search strategy, inclusion/exclusion criteria, dates of search, or meta-analytic pooling methods; thus it appears to be a conceptual and integrative review rather than a systematic review with pre-specified methods. The authors integrate findings at multiple levels of analysis. Evidence types cited include behavioural experiments (e.g., resource-allocation tasks, helping measures), observational and diary studies linking naturally occurring awe to daily outcomes, neurophysiological measures (vagal tone, inflammatory biomarkers, brain-network activation), qualitative and ethnographic accounts from festivals and rituals, and clinical studies of psychedelics that report subjective mystical or awe-like experiences and clinical outcomes. Where available, the review refers to meta-analyses in particular domains (for example, on spirituality and health, and on music interventions), but the extraction does not present a quantitative synthesis protocol. Monroy and colleagues organise the evidence to test a multi-pathway model in which awe-producing elicitors lead to specific mediators that are known to associate with mental and physical health outcomes.

Results

The review presents several empirical characterisations of awe and summaries of findings across domains. First, awe is advanced as a distinct positive emotion elicited by stimuli experienced as vast and requiring accommodation of existing mental models. Cross-cultural and computational work indicates that awe is separable from related emotions such as fear, joy, and beauty. In naturalistic and laboratory samples roughly 75% of reported awe episodes are predominantly positive while about 25% are imbued with threat; cultural variation affects this balance, with some cultures (for example, Japan) showing more threat-based awe. Awe has recognisable expressive features—raised inner eyebrows, widened eyes, an open mouth—and distinct vocalisations. Physiologically, studies report a profile associated with health: increased vagal tone, reduced sympathetic activation, characteristic ‘‘goose-tingles’’ (rather than shuddering linked with fear), elevated oxytocin in response to morally uplifting awe, and lower levels of the inflammatory biomarker interleukin-6 in relation to self-reported awe. Neuroimaging work associates awe with reduced activation of the default-mode network (DMN), a brain network involved in self-referential processing. From these empirical findings the authors identify five mediator pathways. Evidence for the first pathway—neurophysiological shifts—links awe-related vagal tone, reduced sympathetic arousal, oxytocin changes, and lower inflammation with improved mental and physical health indices (optimism, reduced anxiety and depression, cardiovascular and immune benefits). Second, multiple methods (lab, diary, in vivo) show that awe diminishes self-focus or produces a ‘‘small self’’; for example, visitors at Yosemite drew themselves smaller after an awe experience, and diary studies find lower self-centredness on days with awe. Third, experimental and dispositional studies report increased prosociality following awe inductions: participants allocate resources more equitably after an awe video, volunteers exposed to awe are more willing to give time, and field studies (e.g., looking up at towering eucalyptus) found greater helpfulness and reduced entitlement. Fourth, awe is tied to social integration: laboratory and naturalistic studies report increased feelings of common humanity and connectedness to social and natural worlds, and qualitative work from festivals and pilgrimages reports strengthened communal belonging. Fifth, awe provokes meaning-making: because vast stimuli demand accommodation, awe can prompt searches for and experiences of meaning, which in turn associate with lower distress and better mental and physical well-being. The authors report effect sizes for awe’s effects on these five pathways in the range of 0.20 to 0.48. The review then applies this framework to five domains. In nature, studies link contact with natural environments to reduced stress, lower inflammation, improved parasympathetic activity, and immune benefits, with specific work showing awe mediates reductions in rumination and PTSD symptoms among adolescents and combat veterans during outdoor activities. Spiritual and religious engagement is associated with lower depression and reduced all-cause mortality; the authors note that awe is a core component of mystical experience and likely contributes via social integration, meaning, and reduced stress. Collective movement—music, dance, and ceremony—elicits awe and is associated with physiological and psychological benefits: music therapy improves heart and respiratory outcomes in premature infants, and meta-analyses show music reduces stress and pain in adults; synchronous dance increases interconnectedness and pain tolerance (a proxy for endogenous opioid release), and dance-movement therapy reduces anxiety and depressive symptoms. Finally, for psychedelics the review summarises that 50% to 70% of participants report one of the most significant spiritual experiences of their lives—often awe—and that psychedelics produce DMN deactivation and reduced amygdala reactivity, increases in connectedness and altruism, and clinical reductions in depression, anxiety, and addictive behaviours. Across domains, the authors emphasise that threat-based awe may diverge from these benefits and could be harmful.

Discussion

Monroy and colleagues interpret the assembled evidence to support their central claim that awe is a distinct positive emotion that operates through five interlocking processes to promote mental and physical health, provided threat appraisals are not dominant. They propose a parsimonious model in which brief awe experiences shift neurophysiology, reduce self-focus, foster prosociality, strengthen social integration, and prompt meaning-making, all of which are established predictors of better mental and physical outcomes. The authors position this model as a way to unify disparate findings linking nature, spirituality, music, collective ritual, and psychedelics to health benefits. The review is careful to highlight several key caveats and directions. One major qualification is the distinction between positive awe and threat-based awe; the latter shows different neural signatures, weaker prosocial effects, and minimal to negative effects on well-being in some studies. Cultural moderators, individual differences (for example, neuroticism), and contextual factors (such as hierarchical salience) may amplify threat appraisals and therefore alter outcomes. The authors also acknowledge that much of the evidence is preliminary and descriptive: while relationships between awe and each mediator have been empirically identified, the complete causal pathways from specific awe elicitors through mediators to health outcomes remain only partially tested. For future research the review calls for more process-focused and hypothesis-driven studies to unpack the mechanisms depicted in their model. Suggested priorities include experimental tests that isolate physiological mediators (inflammation, vagal tone, DMN activity), rigorous differentiation of positive versus threat-based awe, cross-cultural work to examine moderation, and longitudinal or intervention designs to assess sustained health effects. The authors view these empirical steps as necessary to move from a promising conceptual framework to rigorous evidence about how sublime experiences can ‘‘repair’’ the mind and body.

PSYCHOLOGICAL SCIENCE

In the woods, we return to reason and faith. There I feel that nothing can befall me in life-no disgrace, no calamity (leaving me my eyes), which nature cannot repair. Standing on the bare groundmy head bathed by the blithe air and uplifted into infinite space-all mean egotism vanishes. I become a transparent eyeball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part or parcel of God. The name of the nearest friend sounds then foreign and accidental; to be brothers, to be acquaintances, master or servant, is then a trifle and a disturbance. I am the lover of uncontained and immortal beauty. -How is it that experiences in nature, for example in a garden or local park, surfing, camping, or backpacking, improve mental and physical health? Why is spiritual or religious engagement associated with the reduced likelihood of depression and lengthened life expectancy? How might music or dancing at a festival be good for the body and mind? How might psychedelics serve as a treatment for trauma and anxiety)? Our answer in this review is awe. Robust literatures suggest that experiences of global positive affect (e.g., "I feel good about life") benefit health and well-being. Buoyed by such findings, subsequent studies have turned to examine how experiences of distinct positive emotions, such as amusement or gratitude, benefit health and well-being. These literatures have largely been silent with respect to awe. The purpose of this review is to make the case for how awe "repairs"-in the words of Ralph Waldo. We do so by synthesizing extant literatures. A first is the emergent science of awe, which has mapped its characteristics as a distinct emotion in its patterning of cognition, behavior, and physiology. These discoveries bring into focus how a complex state such as awe, often considered ineffable and even beyond measurement, leads to shifts in health and wellbeing. Our second focus is to extend this reasoning to five domains that reliably bring people awe: nature, spiritual engagement, music, dance, and psychedelics (for evidence on these domains as sources of awe, see. In each of these domains, we develop how awe specifically improves mental and physical health and highlight prospects for future research.

AWE AS A DISTINCT EMOTION

Emotions are brief states that involve distinct experiences, expressive behaviors, patterns of thought, and physiological patterning (e.g.,. The preponderance of research in the first few decades of emotion science focused on only six emotions, which included just one positive state, joy. This has changed. Once ignored, distinct positive emotions, including states such as amusement, compassion, desire, love, and pride, have become a vibrant empirical focus (e.g.,. In this expanding study of positive states, considerable scientific progress has been made in mapping the distinct characteristics of awe (e.g.,. Awe arises in encounters with stimuli that are vast, or beyond one's current perceptual frame of reference. Vastness can be physical, perceptual, or semantic and requires that extant knowledge structures be accommodated to make sense of what is being perceived. Recent daily diary work and more open-ended narrative work in more than 25 cultures found that people experience awe through encounters with other people's courage and kindness, nature, collective gatherings (dance, rituals, and ceremonies), music, visual art, religious and spiritual practice, epiphanies, and birth and death. Is awe a distinct state? Is awe, for example, distinct from fear or horror? Or feelings of joy or beauty? And by implication, might awe promote health and wellbeing in unique ways? Recent evidence suggests that awe is a distinct state in a complex space of eight to 10 positive emotions (e.g.,. The subjective experience of awe captured in self-report measures has been found to be distinct from emotions such as fear, terror, beauty, joy, and interest in largescale computational studies of emotional responses to short evocative videos, music, and visual art. In laboratory studies of awe and daily diary assessments of its naturalistic occurrence, about three quarters of awe experiences are predominantly positive, and about one quarter are imbued with threat and felt to be more negative. The degree to which threat imbues awe is more prominent in some cultures, such as Japan, than other cultures. This suggests that the benefits of awe that we focus on in this review are moderated by culture. More generally, given preliminary evidence finding that threat-based awe is not associated with improvements in well-being (e.g.,, the analysis we offer below would not seem to be characteristic of threat-based awe, which in certain contexts might actually reduce well-being and be harmful to health. Awe is expressed in a pattern of facial muscle movements, including raised inner eyebrows, widened eyes, and an open and slightly drop-jawed mouth, and vocalizations such as "wow" or "whoa". Recent computational approaches found that the facial, bodily, and vocal expressions of awe are distinct among 25 or so expressions of distinct emotions, are recognized across 10 cultures, and are found to occur in similar contexts-for example when watching fireworks-in 144 cultures in a machinelearning analysis of expressions in more than 2,000,000 videos. Select studies show that awe is marked by a distinct neurophysiological profile. Awe is associated with increased goosetingles as opposed to shuddering, which is more tightly linked with fear and dread; increased vagal tone, except in the case of threat-based awe; and reduced activation of the sympathetic nervous system; but see. The awe felt for morally courageous and kind acts is associated with increased oxytocin release. Of many positive emotions, self-reports of awe most robustly predicted lower inflammation, as indexed by the biomarker interleukin-6. Recent neuroscientific studies have found experiences of awe to be associated with reduced activation in the defaultmode network (DMN), an area of the brain typically associated with self-reflective processes. Awe, then, is associated with a profile of elevated vagal tone, reduced sympathetic arousal, increased oxytocin release, and reduced inflammation-all processes known to benefit mental and physical health. influences on thought patterns, social behavior, and physiology (e.g., for rationales, see. Advances in understanding awe-related processes (e.g.,point to five ways that brief experiences of this emotion will benefit mental and physical health, which we summarize in Figure. A first pathway is through shifts in neurophysiology. The physiological profile of awe documented thus farelevated vagal tone, reduced sympathetic activation, increased oxytocin, and reduced inflammation-is associated with enhanced mental health. This is evident in studies of increased optimism, sense of connection, and well-being (e.g.,; an openness to others and prosocial tendencies; reduced anxiety, depression, social rejection (e.g.,; and cardiovascular problems and autoimmune disease. Through awe-related shifts in inflammation, for example, or vagal tone, or reduced DMN activation, experiences of awe will likely benefit mental and physical health. Awe transforms the sense of self-a second pathway through which experiences of awe benefit mental and physical health. An amplified focus on the self has been found to be associated with a variety of mental-health struggles-including depression, anxiety, body-image problems, self-harm, drug abuse, eating disorders-and social problems, such as aggression, racism, bullying, and everyday incivility (e.g.,. Awe, by contrast, reduces the focus on the self. Across diverse methodologies-lab studies, daily diaries, online narratives, in vivo nature studies-and elicitors of awe, such as images of nature or visual art, awe diminishes self-focus (e.g.,. For example, in a study conducted at Yosemite National Park, participants were asked to draw a picture of themselves after visiting the tunnel viewpoint, a section of the park that provides a wide scenic view of the entire valley-undoubtedly, an awe-inducing experience Model for awe as a pathway to mental and physical health. This model shows that awe experiences will lead to the mediators that will lead to better mental and physical-health outcomes. Note that the relationships between awe experiences and mediators, and mediators and outcomes have been empirically identified; the entire pathways have only recently begun to be tested. One-headed arrows suggest directional relationships, and two-headed arrows suggest bidirectionality. DMN = default-mode network; PTSD = posttraumatic stress disorder.. The researchers found that people tended to draw themselves in a much smaller relative physical size compared with a control condition, another positive experience at Fisherman's Wharf in San Francisco. These findings were corroborated with daily diary findings showing that on days when people reported experiencing awe, they perceived themselves as smaller. This vanishing of self-focus brought about by awe, a recent set of studies found, mediates the relationship between naturalistic and laboratory experiences of awe and daily stresses. Brief experiences of awe, then, are likely to bring about a host of mind-body benefits through a transformed self. A third pathway by which awe may improve mental and physical health is through enhanced prosociality. Empirical studies have found that transient experiences of awe in the lab and in naturalistic contexts leads to cooperation, sacrifice, and sharing. For example, a series of studies found that people higher in dispositional awe-as measured with items such as "I often feel awe")-tend to be more prosocialand are more generous in economic games; but see. In lab studies, experimentally induced experiences of awe (via a nature video) have been found to lead people to prefer a more prosocial, equal distribution of resourcesand to be more willing to volunteer their time to charity compared with another positive emotion. Moreover, studies in nature have found behavioral evidence for the awe-prosocial association. In a study examining whether awe would influence altruistic behavior after looking up at a grove of towering eucalyptus trees (awe condition) or looking at a tall building (neutral condition), after the awe induction, participants were more helpful toward the experimenter (i.e., picked up more pens) and reported feeling less entitled compared with the neutral condition. Relevant empirical evidence has consistently found that such prosocial relationality elevates well-being (e.g.,and might even boost life expectancy (e.g.,. As illustrated in Figure, a fourth way in which awe will bring about elevated mental and physical health is through the sense of being integrated into strong social networks, one of the strongest predictors of mental and physical well-being (e.g.,. Emotions by their very nature structure patterns of social interactions (e.g.,. In studies of awe of different kinds-whether experienced via a written online narrative, via an in-lab induction, or in vivo-awe led people to feel common humanity with others, integrated within stronger social networks, and overall more connected to the social and natural world. Finally, a fifth pathway by which awe is likely to enhance mental and physical health is through elevating the individual's sense of meaning. Meaning, or sense of purpose, is found in making sense of life events, finding connections between current events and the past, and one's values and social relationships. A sense of meaning has been associated with reduction of distress and depression, increases in personal growth, and greater mental and physical wellbeing (for reviews, see. In experiences of awe, the need for accommodation that arises as a result of encountering vast stimulicore appraisals of awe-leads to a meaning-making process. Experiences of awe can lead people to seek meaning in specific social contextsand more generally about the trajectory of life. The search for meaning evoked by awe is likely to lead to greater mental and physical health.

CASE STUDIES OF THE SUBLIME: HOW AWE PROMOTES MENTAL AND PHYSICAL HEALTH

Awe often arises in transcendent encounters, in nature for example, or at a concert or in spiritual practice or during a psychedelic experience. These encounters often leave people feeling enlivened, robust, and strengthened, but in ways that seem beyond words. We suggest that awe-related processes outlined in Figureprovide one approach to unpacking this mystery of awe, how it can often repair and enhance physical health and well-being. Central to our argument is that experiences of awe can benefit physical health and well-being. Recent empirical work lends credence to these claims. Studies have found that experiences of awe, in particular those not involving appraisals of threat, above and beyond other positive emotions and global positive affect reduce stressand posttraumatic stress disorder (PTSD) symptoms in veterans and at-risk youths. Other studies have found that experiences of awe-in the lab, in naturalistic contexts, and when assessed with daily diary methodsincrease the sense of social integration, personal well-being, and sense of having ample time. Again, we note that threat-based awebeing in the middle of an earthquake or flood, feeling judged by an omnipotent God, or being part of a protest march that turns violent-are not likely to bring about the benefits of interest here and could yield the mind-and-body profile of chronic stress and trauma instead. With this caveat in mind, we now consider how these findings we have just reviewed set the stage for considering our second aim-to highlight pathways through which awe may repair the mind and body across five realms of transcendent experience.

NATURE

In different countries with varying landscapes and ecosystems, nature is one of the most common elicitors of awe. Recent reviews found that contact with natural environments promotes more robust health outcomes, including reductions of stress, reduced inflammation, increased parasympathetic activity, and improved immune functioning. Experiences of awe have been proposed to be one of the pathways through which immersion in nature benefits mental and physical health. This thesis, in keeping with our own, has been supported by recent scientific studies that found that awe in nature reduces rumination, reduces stress, and elevates well-being. For example, in a study involving adolescents from underresourced inner-city schools and combat veterans, awe experienced outdoors during a rafting trip promoted reductions of stress and PTSD symptoms and improvements in well-being. In addition, in college students, daily nature experiences improved well-being via feelings of awe. A next generation of studies would be well served by testing predictions outlined in Figureto more precisely unpack the benefits of nature immersion. Relevant work could examine, for example, how the small self produced by nature may reduce stress, how the sense of prosociality that nature immersion brings about through awe (e.g.,accounts for how nature immersion boosts well-being, or how the shifts in neurophysiology, for example inflammation or vagal tone, brought about by experiences of awe in nature might explain the effect of nature immersion on mental and physical health.

MYSTICAL ENCOUNTERS AND SPIRITUALITY

In meta-analyses and specific empirical studies, a sense of spirituality-the feeling of being in relation to supernatural forces, often perceived as Divine-and religiosity-engagement with a religion's formalized beliefs and practices-have been shown to benefit the mind and body. Spirituality and religiosity have been linked to stronger social connections, reductions in anxiety and depression (e.g.,, and reduced all-cause mortality, including deaths from cancer and cardiovascular disease. These findings beg the question of how spiritual and religious engagement benefit the mind and body. The pathways are likely to be many, from social integration to meaning making. One pathway is through awe. In the writings of William) and more recently in scientific work, awe is central to the mystical experience that people often deem "spiritual." This experience is cultivated by religious ritual, ceremony, and practice (e.g., prayer, chanting, or sacred music). In fact, "awe" is a key item in the most widely used measure of mysticism. Awe, as William James suggested, is core to the religious experience. Figurehighlights how the awe that arises during spiritual and religious engagement might benefit mental and physical health. To the extent that transformative spiritual experiences bring about shifts in a sense of self, for example, one might expect this facet of awe to reduce subjective and physiological stress. Religious ceremony and spiritual practices often involve strong shared experiences of awe, which likely benefit health and well-being (e.g.,. It is clear that experiences of awe embedded in spiritual and religious practices are likely to encourage prosocial tendencies) and a sense of meaning, both of which have been found to enhance mental and physical health. In many ways, spiritual and more formal religious traditions bring together various beliefs and practices that cultivate the shared experience of awe (e.g.,. The concrete influences of awe on sense of self, physiology, or prosocial relationality reveal how spiritual experiences, so often considered ineffable, benefit the mind and body.

COLLECTIVE MOVEMENT: MUSIC, DANCE, AND CEREMONY

Collective synchronous movements, such as collective rituals, religious ceremonies, singing in chants, prayers, celebrations, and appreciating music and dance, can all induce awe (e.g.,. They do so, intuition suggests, through various means: a shared neurophysiological profile, the diminishing of the self, a sense of being part of a collective. The analysis we offer here is that through awe, collective movement-in ceremony and ritual, in dance, and in shared music-can benefit health and well-being. Given the complexities of this scientific endeavor-such as data collection and the statistics of interdependent data-this possibility has attracted less systematic attention than studies of nature immersion, for example, but the results are promising and point to new areas of inquiry. For example, awe surfaced in the accounts of Irish celebrants after St. Patrick's Day parades and of pilgrims to the Magh Mela Hindu festival in India. In this qualitative work, celebrants reliably spoke of being part of something much larger than their self, a spiritual community, and moved to a heightened sense of purpose and enhanced physical robustness. Similar effects on awe been found in both religious and nonreligious collective gatherings, such as music and arts festivals. Music is found to be one of the common elicitors of awe. For instance, when listening to a moving piece of music, people may feel taken aback, feel small and part of the music, and be transported to a different state of mind with different laws of time, space, and causality. Empirical studies have yielded evidence that music has many benefits for physical health. For example, in premature infants, music therapy has beneficial effects on heart and respiration rate, weight gain, and days of hospitalization. In adults, meta-analyses have shown that music has beneficial effects on physical and subjective stress, pain, mental disorders, and overall well-being. Given these broad benefits of listening to music (and presumably performing), our focus on awe-related processes points to concrete hypotheses to begin to understand how music repairs the mind and body. In dance, whether alone or in a group, people express and feel awe. People also tend to report feeling that their self merges with others-a sense of interconnectedness. For example, in a study from Brazil, high schoolers engaged in dance-like movements of the arms and head either in synch with others to the beat of a metronome or out of synch with those nearby and participants who "danced" with exertion with others felt more interconnected with those students. They also could tolerate more pain, a sign of elevated opioids that accompanies feelings of merging with others. Moreover, in the study of dance, evidence suggests overall improvements in physical and psychological health. For example, studies of dance-movement therapy have found reductions in anxiety, stress, and depressive symptoms and improvement in overall quality of life (for review, see. This evidence suggests that dance enhances mental and physical health. As illustrated in Figure, we suggest that awe is one account of dance's many likely benefits.

PSYCHEDELICS

"Psychedelics" refers to a wide array of compounds, both natural and synthesized, that alter serotonin levels in the brain. Examples include psilocybin, LSD, MDMA, DMT (ayahuasca), and mescaline (peyote). In the study of psychedelics, psilocybin and MDMA are the most widely studied compounds. Across different studies, 50% to 70% of participants reported that psychedelics produced one of the most significant spiritual experiences of their lives and often centered on intense experiences of awe. Recent studies have also found that psychedelics have beneficial effects on anxiety, depression, substance abuse disorders (e.g., smoking, alcoholism), obsessive-compulsive disorder, and PTSD (see reviews byas well as improvements in well-being. A central hypothesis to emerge in the literature on psychedelics is that their benefits derive from the experiences of intense awe they occasion. In keeping with this thinking, a study found that psychedelics, like awe, consistently deactivate the DMN, the neurophysiological equivalent of "ego dissolution". Psychedelics reduce activation in threat-related regions of the brain-the amygdala-allowing people to ruminate less on trauma, obsessive ideas, addictions, or even the imminence of dying. Psychedelics lead people to feel greater connectedness to others and the world in general, feel fewer distinctions with others, and be more altruistic-awe-like shifts in the sense of self, relationality, and prosociality. Most directly, psychedelics can reduce depression, anxiety, and addiction through experiences of awe. The literature on psychedelics and that on nature have most explicitly considered awe as a mediating process between transcendent domain and health and well-being benefits. Again, we note the opportunity for more precise theorizing, but threat-based awe in these contexts may account for why psychedelics or nature immersion might not yield health and well-being benefits. The reasoning we advance in Figurehighlights a host of more specific hypotheses worthy of scientific study.

IMPLICATIONS AND FUTURE SCIENTIFIC INQUIRY

Recent advances in the science of awe reveal it to be a distinct positive emotion that engages five processes that can be beneficial for mental and physical health, when threat appraisals are not salient in the unfolding experience of awe. These processes include shifts in neurophysiology, a diminished focus on the self, increased prosocial relationality, greater social integration, and a heightened sense of meaning. The effects of awe on these five pathways are substantial, ranging from .20 to .48 in size (e.g.,. This suggests that experiences of awe-whether experienced in controlled lab settings or in more ecologically valid settings, such as out in nature-have meaningful consequences on neurophysiology, the self, prosociality, social integration, and meaning. All five of these processes benefit the mind and body, suggesting that awe is a pathway to mental and physical health. As we noted in different places in this review, the awe-health pathway we propose here may be specific to positive awe experiences. Threat-based awe is experienced as more negativeand may produce diverging effects on mental and physical health. For example, studies examining threat-based awe have found diverging neural activity, lower effects on prosociality, and minimal to negative effects on well-being compared with positive awe experiences. It will be critical for future work examining the predictions outlined in Figureto disentangle positive and threatbased awe experiences, as well as likely amplifiers of threat in awe experiences: such as culture; individual differences, such as neuroticism; and contextual factors, such as the salience of vertical hierarchies. In this review, we have made the case for how domains that have been the provenance of awe experiences for thousands of years-nature, spirituality, music, dance, and psychedelics-bring about mindbody benefits through awe-related processes. In each of these realms, it is clear that awe is prominent, and the evidence for its benefits is promising and preliminary. The discoveries of how awe shifts physiology, the sense of self, orientations to others, and the search for meaning point to precise process-like studies for understanding how sublime realms, from nature to music, can benefit the mind and body.
