THE ROLE OF NATURE-BASED EXPERIENCES
1 The Role of Nature-Based Experiences in the Development and Maintenance of Wellness Eric Brymer, Thomas F. Cuddihy, Vinathe Sharma-Brymer Institute of Health and Biomedical Innovation and School of Human Movement Studies Queensland University of Technology, Brisbane QLD Australia 4059 Correspondence: Dr Eric Brymer School of Human Movement Studies Queensland University of Technology Kelvin Grove Campus Brisbane, QLD Australia 4059 Eric.firstname.lastname@example.org Ph: 61 7 31383511 Words: 6629 THE ROLE OF NATURE-BASED EXPERIENCES 2 Abstract Wellness is now seen as central to redefining the National Health agenda. There is growing evidence that contact with nature and physical activity in nature has considerable positive effects on human health. At the most basic level humanity is reliant on the natural world for resources such as air and water. However, a growing body of research is finding that beyond this fundamental relationship exposure to the non-human natural world can also positively enhance perceptions of physiological, emotional, psychological and spiritual health in ways that cannot be satisfied by alternate means. Theoretical explanations for this have posited that non-human nature might 1) restore mental fatigue, 2) trigger deep reflections, 3) provide an opportunity for nurturing and 4) rekindle innate connections. In this paper the authors show how human wellness is strongly connected to their relationship with the natural world. This paper points to how non-human nature could be better utilised for enhancing human health and wellness. Key words: Health, wellness, natural world, ecopsychology THE ROLE OF NATURE-BASED EXPERIENCES 3 Introduction “Send your children out to renew themselves, so to speak, send them to regain in the open fields the strength lost in the foul air of our crowded cities” (Rousseau, 2008, p. 40, trans. 2008) The natural environment has a profound influence on human health (Barton & Pretty, 2010; Brymer, 2009; Brymer & Oades, 2009; Brymer, Schweitzer, & SharmaBrymer, 2010; Gorrell, 2001; Leather, Pyrgas, Beale, & Lawrence, 1998; Maas et al., 2009; Maas, Verheij, Groenewegen, de Vries, & Spreeuwenberg, 2006; Maller et al., 2008; Reser, 2008; Townsend & Moore, 2005; Weber & Anderson, 2010). In a recent review of the health benefits of exposure to nature Maller et al. (2008) stated: “That the natural environment is a key determinant of health is unquestionable” (p. 5). This is also recognised by the Australian Psychological Society and outlined in a position statement published in 2008 which stated “It is clear that the well being and integrity of natural ecosystems and the biophysical environment are integral to human health and well being” (Reser, 2008, p.4). At the most basic level humanity is reliant on the natural world for resources such as air and water. However, a growing body of research is finding that beyond this fundamental relationship exposure to the nonhuman natural world can also positively enhance perceptions of physiological, emotional, psychological and spiritual health in ways that cannot be satisfied by alternate means (Burls, 2007; Herzog & Strevey, 2008; Louv, 2009b; Maller et al., 2008; Pryor, Townsend, Maller, & Field, 2006; Roszak, 1992; Schultz, 2002; Townsend & Moore, 2005; Wilson, 1984). THE ROLE OF NATURE-BASED EXPERIENCES 4 However, since the industrial revolution, the development of an urbanised lifestyle has reduced opportunities for contact with the natural world (Maller et al., 2008; Townsend & Moore, 2005). Recently, the Australian Bureau of Statistics (Australian Bureau of Statistics, 2006a, 2006b) reported that adults spend less than 20 minutes per day outdoors. Conversely, more than half of their daily leisure time, two hours and twenty minutes, was spent on audio-visual media (Australian Bureau of Statistics, 2006a, 2006b). In 1997 Australian adults reported spending approximately 27 minutes a day outdoors and 130 minutes a day on audio visual media (Australian Bureau of Statistics, 2006a, 2006b). This trend of decreased time outdoors is continuing. Research focusing on young people also shows that young people are spending less time outdoors (Hofferth & Sandberg, 2001; Rydberg, 2007a, 2007b). Hofferth and Sandberg (2001) reported that American children under the age of 12 years spent on average 34 minutes a week outdoors compared to 12 hours a week watching television. Between 1997 and 2003 the proportion of 9-12 year olds who spent time playing outside declined by 50 percent (St George, 2007). Louv (2008) considered this disconnection a crisis which he termed “Nature Deficit Disorder.” Essentially, a growing body of research from disciplines such as psychiatry, ecology, psychology, planning, medicine, health, leisure and recreation is demonstrating that the natural world is essential for human health. The aim of this article is to outline how the natural world influences one aspect of the health continuum, human wellness. Human Wellness and the Common Dimensions: A Brief Overview As a holistic concept wellness is still a developing field of study and as such definitions of wellness have evolved over time. However, the core of the “human wellness” concept is the promotion of a positive and optimal state of health. For the THE ROLE OF NATURE-BASED EXPERIENCES 5 purposes of this article human wellness is defined as the “positive component of optimal health” (Corbin, Welk, Corbin, & Welk, 2009, p. 4). Thus, human wellness focuses on the development of a lifestyle that encourages ultimate health. Whereas good health might be considered as freedom from illness and disease, wellness is about continuing the journey towards an optimal state of individual health (Corbin et al., 2009; Myers, Sweeney, & Witmer, 2000; Roscoe, 2009). From this perspective a focus on wellness is also a proactive approach to reducing the chances of illness, especially those that are associated with poor lifestyle (Corbin et al., 2009). More specifically, human wellness is generally considered to be the integration of various dimensions that, when combined effectively, enhance an individual’s quality of life and their ability to contribute to society (Hettler, 1980). The most common of these dimensions are emotional wellness, physical wellness, social wellness, intellectual wellness, occupational wellness and spiritual wellness (National Wellness Institute, 2009). Whereas good health in each of these dimensions is characterised by freedom from illness, wellness is characterised by an individual’s journey to achieving optimal functioning (Corbin et al., 2009). From this standpoint emotional wellness is therefore conceptualised as “an awareness and acceptance of feelings, as well as a positive attitude about life, oneself and the future” (Roscoe, 2009, p. 218). As such emotional wellness is not just freedom from emotional or mental illness rather emotional wellness is the ability to constructively and positively deal with personal feelings and daily events. Physical wellness is about the proactive effort to maintain physical activity and good nutrition coupled with the maintenance of healthy lifestyle choices. Physical wellness is also about acceptance of physical states and a focus on the journey towards THE ROLE OF NATURE-BASED EXPERIENCES 6 realising personal potential (Roscoe, 2009; Sackney, Noonan, & Miller, 2000). A physically well person will be undertaking regular physical activity, making healthy dietary choices and effectively utilising medical services. Social wellness emphasises the quality of interactions with others. A socially well person cultivates effective relationships that enhance the quality of life for all people involved and is willing to both receive and give support (Corbin et al., 2009; Horton & Snyder, 2009). Intellectual wellness concerns learning for learning’s sake. A person who is intellectually well searches for mental stimulation for its own sake (Horton & Snyder, 2009). Occupational wellness describes the fit between the work place and the worker. High occupational wellness correlates with high levels of perceived work satisfaction and life enrichment (Scheer & Lockee, 2003). Spiritual wellness is the realisation of a shared connection to a greater power and the search for purpose and meaning. A spiritually well person will feel fulfilled (Roscoe, 2009). In contrast to all the other dimensions spiritual wellness and spiritual health are considered synonymous (Corbin et al., 2009). Spiritual wellness is typically construed as being fundamental to all other wellness dimensions (Chandler, Holden, & Kolander, 1992). In the following sections the authors first outline studies that demonstrate the link between human wellness and exposure to the non-human nature and then outline current theoretical explanations for these findings. Nature and Wellness For centuries psychologists and philosophers have recognised the importance of the natural world to human health and wellbeing (Deloria, 1994; Dewey, 1958; Harvey, 2000; Jung, 2008; Knudtson & Suzuki, 1996; Marano, 2008; Watts, 1970; Watts, 2003). In recent years, the relationship between the natural world and health has been THE ROLE OF NATURE-BASED EXPERIENCES 7 explored from various perspectives. Examples include ecopsychology, outdoor education and recreation, wilderness and adventure experiences, “green exercise” (physical activity in green spaces), psychiatry, public health and horticulture (Brymer, 2009; Brymer & Cuddihy, 2009; Brymer & Oades, 2009; Brymer et al., 2010; Doucette, Ransom, & Kowalewski, 2007; Duncan, 1998; Herzog & Strevey, 2008; Noddings, 2006; Wilson, 1984). Researchers have described the benefits of viewing nature (Leather et al., 1998), connecting with nature (Kaplan & Talbot, 1983), green spaces in urban environments (Tzoulasa et al., 2007), brief encounters in nature (Hull, 1992; Woolley, 2003) and extended encounters in nature (Hull & Michael, 1994) and even the difference between exposure to virtual nature and actual nature (Mayer, Frantz, Bruehlman-Senecal, & Dolliver, 2009). In the following sections the authors review literature that focuses on the role of the natural world for the development of human wellness. Exposure to nature has been shown to improve emotional wellbeing and relieve stress (Leather et al., 1998), increase positive mood (Maller, Townsend, Pryor, Brown, & St Leger, 2006), enhance life skills (Mayer & Frantz, 2005), reduce mental fatigue and increase concentration (Maller et al., 2008) and reduce the tendency for aggressive behaviour (Kuo & Sullivan, 2001). Mayer, Frantz, Bruehlman-Senecal and Dolliver (2009) reported on three studies that examined the effects of exposures to nature on positive affect and the ability to reflect on a life problem. A 15 minute walk in a natural setting was compared to similar walk in an urban setting, watching a video of nature and watching a video of an urban setting. They found that both emotional wellness and the ability to reflect on a life problem were enhanced by exposure to actual and virtual nature as compared to urban settings. The influence of actual nature was most acute. They stated that besides the psychological benefits demonstrated THE ROLE OF NATURE-BASED EXPERIENCES 8 through their studies; their previous research also indicated that people who felt more connected to nature were more likely to demonstrate caring by engaging in ecofriendly acts. Doucette, Ransom and Kowalewski (2007) described a winter camp of seven to ten days in the Canadian Arctic involving high school students between 1995 and 2006. The instructors included both aboriginal guides and non-aboriginal high school teachers and visiting university professors. The aim of the camp was to facilitate an experience where students were experientially introduced to “nature as nurture” for humanity as distinct from learning about nature in the class room. The authors concluded that teaching nature as nurture resulted in an improved ability to handle fear, improved self-confidence, improved self-reliance and improved understanding of the benefits of social cooperation. The desire to seek out brief nature-based experiences is increasing (Eagles, 2001). While this trend has been in practice in the western countries for some time now mostly for leisure (Scherl, 1989), developing countries are catching up. This is especially true for young adults. One of the reasons is that wilderness experiences can increase perceived wellness in youth and young adults coming from fast-paced city lifestyle. Researchers have found that wilderness experiences improve self-perception (Young & Crandall 1984), measures of well-being (Russell, 2005), self-concept (Kaplan, 1984) and improved occupational, emotional, physical and intellectual wellness (Miner, 1990; Priest, 1990). An early research finding, focusing on using wilderness activities for improving selfconcept recommends the importance of long and continued wilderness participation (Schreyer, Williams, & Haggard, 1990). Schreyer et al. highlighted the role of THE ROLE OF NATURE-BASED EXPERIENCES 9 wilderness values in the process of self-concept formulation and concluded that wilderness settings are important for the enhancement of human wellness. Other studies that demonstrate the positive role of being with nature include Gorrell’s (2001) reflections on his experience of a 10-day Outward Bound course in the Costa Rica Rainforest. After the course, he wrote that he felt “a stronger sense of confidence and trust in myself” (2001, p.68). Interactions with animals (Antonioli & Reveley, 2005; Muscat, 2001), such as experiences with dolphins have been associated with developments in emotional and psychological wellness. Natural or green spaces have also been shown to promote physical activity and physical wellness (Booth, Owen, Bauman, Clavisi, & Leslie, 2000; Pretty, Griffin, Sellens, & Pretty, 2003). A study carried out in Australia, found that moderate to energetic gardening can provide the level of physical activity necessary to reduce the risk of mortality in high risk groups (Holbrook, 2009). Research studies published in the UK, Europe and USA are increasingly finding that physical activity in green spaces have benefits beyond physical activity alone (Corkery, 2004; de Vries, Verheij, & Groenewegen, 2001; Giles-Corti & Donovan, 2003; MIND, May, 2007; Mitchell & Popham, 2007; News, NA; Pretty, Hine, & Peacock, 2006; Pretty et al., 2007; Pretty, Peacock, Sellens, & Griffin, 2005; Pryor, Carpenter, & Townsend, 2005; Rappe, Koivunen, & Korpela, 2008; Russell, 2002; Sempik, 2008; Takano, Nakamura, & Watanabe, 2002; Thompson, Corkery, & Judd, 2007). For example, Takano et al. (2002) found that nearby green spaces seem to encourage walking groups among senior citizens which also enhances their social and physical wellness. Pretty, Hine and Pretty (2007) found that a regular walk in an urban green space can increase subjective experiences of mental and emotional wellness. Buzzell (2008) described a THE ROLE OF NATURE-BASED EXPERIENCES 10 new social-environmental initiative designed to channel worry and concern about the future (eco-anxiety) into constructive and enjoyable community activities and actions. A study carried out by MacKay & Neill (2009) investigated the effects of physical activity in green spaces on anxiety levels. They found that whilst intensity and duration did not impact on state anxiety, higher degrees of perceived “greenness” of the exercise environment were associated with greater reductions in state anxiety. The researchers suggested that green exercise warranted further investigation for its potential physical and mental health benefits. In particular they outlined the need for improved measuring and understanding of the role of the presence of greenery in the environment. Harris (2009) reported that gardening provided an opportunity to develop self-esteem in refugee and migrant communities in Queensland. Other studies have shown that gardeners have a higher life satisfaction and rate their health and physical activity levels higher than non-gardeners (Waliczek, Zajicek, & Linebereer, 2005). Horticultural activities (such as gardening) have also been linked to improved levels of social, physical and occupation wellness (D’Abundo & Carden, 2008). The natural world can also foster social and occupational wellness (Greene, 2009; Ruter, 2009). Ruter (2009) showed how agriculture has been used for the development of social and occupational wellness in India. Community gardening and farming is employed to advance vocational opportunities and provide a means for fostering community peace and mindful association with nature. Greenleaf & Williams (2009) have argued for the use of ecological perspectives as a medium for supporting social justice advocacy, thus reflecting mindful practices for healthy community living. In addition, studies in the US have found that workers report less stress and higher job satisfaction if their workplace includes views of nature (Kaplan, THE ROLE OF NATURE-BASED EXPERIENCES 11 1993; Kaplan & Kaplan, 1989). These benefits seem to cross cultural boundaries (Greene, 2009; Ruter, 2009). Researchers have established positive links between nature and improved behaviour in children and young adults (Banderoff & Scherer, 1994; Han, 2009; Humberstone & Lynch, 1991; Kuo & Taylor, 2004; Louv, 2009a; Noddings, 2006; Riebel, 2001; Robertson & Kiewit, 1998; Russell, 2002, 2003). Exploration in the outdoors, gardens, backyards, parks, wilderness and many such environments encourage and nurture curiosity, engagement, focused learning, mindfulness and reflective practice. (Han, 2009; Pretty et al., 2009; Said, 2006; Stolar, 2009; Ungar, Dumond, & Mcdonald, 2005; Wells, 2000). Taylor and others (Kuo & Taylor, 2004; Taylor, Kuo, & Sullivan, 2001) have also demonstrated that nature exposure has a positive influence on concentration and the behaviour of children diagnosed with Attention Deficit Disorder. Research is also finding that opportunities to connect with nature when a child are important for the promotion of wellness for future adults. For example, Mayer and Frantz (2005) considered that opportunities to connect with nature in childhood promotes the value of green spaces for refuge from stress and anxiety (Mayer & Frantz, 2005). The spiritual value of non-human nature has also been explored from various traditions including Hinduism, Sufi practice, Indigenous life practices, Tibetan Buddhist meditation, Taoist practices, Buddhist tradition and also Western philosophical conventions (Hughes, 2008; Jung, 2008; Watts, 1970). For example, Taylor (2000, 2001) argued that experiences as diverse as shamanic rituals and extreme sports can result in a connection with non-human nature. Such experiences promote an understanding of ultimate meaning and the realisation of the THE ROLE OF NATURE-BASED EXPERIENCES 12 transformative power of nature. However, for this to happen the experience generally promotes a shift from the current anthropocentric or materialistic understanding where nature is deemed to be other to humankind and valued only for its worth to humanity (Mathews, 2006; Vining, Merrick, & Price, 2008). Instead the experience advances a realisation that humanity is simply a part of the natural environment (Sanford, 2007; Taylor, 2007). In summary, research is amassing considerable evidence that non-human nature has a profound influence on human wellness. Exposure to virtual nature, opportunities to view nature through a window, experiences of brief encounters with nature, programs that emphasise extended encounters with nature and even bringing nature indoors seems to be beneficial for at least one of the dimensions of wellness. However, as wellness is dependent on the effective integration of all the dimensions it would seem that the strongest nature-based experiences are those where a person is exposed to nature in such a way that there is an opportunity for actual contact and the development of feelings of connection to non-human nature. In the following section the authors outline some theoretical perspectives on how exposure to nature might facilitate optimum wellness. Explanations for these Findings Explanations for the role of nature in human wellness cross biological, psychological and genetic boundaries (Pilisuk, 2001; Wilson, 1984). For example, Pilisuk (2001) argued that the natural world provides an essential opportunity to experience being part of a larger natural ecology and an opportunity for selfless caring, where caring and nurturing are considered core components of emotional wellness. For Wilson (1984) human beings are so deeply connected to non-human nature that all human THE ROLE OF NATURE-BASED EXPERIENCES 13 functions, including wellness, are dependent on a positive relationship to non-human nature. Segal (1997) argued that the natural world might act as a mirror whereby events in the more-than-human natural world allow participants to reflect on their own thoughts and feelings. This in turn exposes a new sense of self awareness and emotional development. Duncan (1998) also reported that natural settings can enhance self awareness and acceptance. However, he considered that measuring and understanding the psychological benefits of visiting wilderness remains one of the least developed and understood bodies of knowledge about wilderness. Kaplan (1995) argued that nature has an abundance of characteristics that are necessary for mental restoration. Specifically, Kaplan believed that everyday life is filled with events that require an immense amount of direct psychological attention. Eventually and inevitably this effortful attention leads to mental fatigue: “Mental fatigue occurs when after prolonged and intense use, the capacity to direct attention is reduced and the capacity to ward off distractions diminishes” (Berto, 2005, p. 249). Exposure to nature provides a refuge from the need for focused attention because nature-based experiences do not need direct psychological attention. Being in nature provides an opportunity for being away from the everyday, for opening up feelings of fascination, for providing a sense of extent (a sense of something larger) as well as a deep realisation of a special compatibility. All of which combine to bring about a restorative effect. Kaplan called this effect Attention restoration theory. Ecopsychology has also been presented as a means to understanding the relationship between non-human nature and human beings. Following the approach of many of the “Wisdom” and “traditional” perspectives those espousing ecopsychology accept that THE ROLE OF NATURE-BASED EXPERIENCES 14 human beings are simply a part of nature (Winter & Koger, 2004). That is, from an ecopsychological perspective, nature and humanity are ineradicably linked and modern urban lifestyles are promoting an alienation from non-human nature. Optimal wellness can only be achieved through the experiential realisation of this relationship (Armstrong, 1995; Roszak, 1992). Thus, exposure to nature might provide opportunities to reconnect with non-human nature and, as a result, enhance wellness. There is a deeply bonded and reciprocal communion between humans and nature. The denial of this bond is a source of suffering both for the physical environment and for the human psyche, and the realization of the connection between humans and nature is healing for both. (Davis, 1998, p. 5) Exposure to non-human nature has benefits for a variety of wellness related constructs. Theoretical perspectives suggest a range of possibilities 1) contact with nature acts as a medium for restoration, 2) contact with nature provides an opportunity for emotional care, 3) nature provides a mirror for in-depth reflection or 4) contact with nature provides an opportunity to rekindle an innate union. That is theoretical perspectives point to broad possibilities as to why being in nature enhances wellness. However, while the evidence points to a positive relationship between exposure to nature and human wellness the nature of this relationship is still unclear (Maller et al., 2008). That is, while research has amassed considerable evidence that exposure to non-human nature provides considerable benefits to human wellness, it is still unclear how nature supports these benefits. Conclusion THE ROLE OF NATURE-BASED EXPERIENCES 15 For this article the authors defined wellness as a journey towards optimal health and shown how this can only be realised through the integration of various dimensions. From this perspective wellness is typically characterised by a balance of the physical, emotional, social, spiritual, occupational and intellectual dimensions. A growing body of evidence-based literature supports the notion that contact with nature and physical activity in nature has a profound positive influence on human wellness. Exposure to virtual nature, opportunities to view nature through a window, experiences of brief encounters with nature, programs that emphasise extended encounters with nature and even bringing nature indoors seems to be beneficial for at least one of the dimensions of wellness. Explanations for these findings include those that emphasise an opportunity to nurture and care for nature, an opportunity for restoration and the reconnection with an innate aspect of being human. However, optimal wellness is reliant on the effective integration of all the wellness dimensions and spiritual wellness is commonly considered to be central to other wellness dimensions. From this perspective, the nature-based experiences that are most likely to augment optimal wellness are those where a person is exposed to nature in such a way that there is an opportunity for actual contact and feelings of connection. Exposure to nature is beneficial for human wellness. However the evidence presented in this article also points to the need for further research into the precise nature of this relationship. For instance, further empirical research might investigate the specific role of different components of the natural world in addressing different types of human health and wellness issues. In this way evidence can better inform health practitioners and policy makers about how best to encourage nature-based experiences. This will benefit humanity immensely.
