An Analysis of Theoretical Perspectives in Research on Nature-Based Interventions and Pain.

Chronic pain results from a complex series of biomechanical, inflammatory, neurological, psychological, social, and environmental mechanisms. Pain and pain-related diseases are the leading causes of disability and disease burden globally. Employing nature-based interventions for the treatment of pain is an emerging field. Current theory driving the suggested mechanism(s) linking the pain reducing effects of nature-based interventions is lacking. A two-step approach was taken to complete a theoretical review and analysis. First, a literature review was completed to gather a substantive amount of research related to theoretical frameworks on the topic of nature-based interventions and pain. Secondly, a theoretical analysis as proposed by Walker and Avant was completed to explore current theoretical frameworks accepted in the literature on nature-based interventions and pain. Stress reduction theory and attention restoration theory were the most common theoretical frameworks identified. Neither theoretical framework explicitly identifies, describes, or intends to adequately measure the concept of pain, revealing a limitation for their application in research with nature-based interventions and pain. Theoretical development is needed, as it pertains to nature-based interventions and pain. Without this development, research on nature-based interventions and pain will continue to use proxy concepts for measurement and may result in misrepresented findings.

Simulated Forest Immersion Therapy: Methods Development.

Shinrin-yoku, forest bathing, may provide relief from chronic and breakthrough pain in patients with axial spondyloarthritis and improve immune function through increasing NK cell numbers and activity and their downstream effectors, perforin and granulysin, after chemo- or radiation therapy in breast and prostate cancer patients. The aim of this paper is to describe the study protocol for a simulated forest immersion therapy using virtual reality and atomized phytoncides, volatile organic compounds found in forested areas designed to effect positive change for these two patient populations. The setting, including the room set up and samples with inclusion/exclusion specific to this type of intervention, is outlined. Measures and calibration procedures pertinent to determining the feasibility of simulated forest immersion therapy are presented and include: ambient and surface room temperatures and relative humidity in real time, ambient ultrafine particulate matter, ambient droplet measurement that coincides with volatile organic compounds, specific phytoncides, and virtual reality and atomization of phytoncide set up. Particular lessons learned while training and setting up the equipment are presented. Simulated forest immersion therapy is possible with attention to detail during this early phase when development of methods, equipment testing, and feasibility in deploying the intervention become operational. The expected outcome of the development of the methods for this study is the creation of a standardized approach to simulating forest therapy in a controlled laboratory space.

Rural Latino parent and child physical activity patterns: family environment matters.

BACKGROUND: Rural Latino children and adults are less active than urban and non-Latino counterparts. We examined physical activity (PA) patterns of rural Latino children and their parents, and explored parental beliefs about and reported barriers of Latino family physical activity. Latino families in a rural area in eastern Washington state, with children in grades 3-5 were included. METHODS: We used mixed methods. Children (n = 27) and parents (n = 25) wore an accelerometer for 5 days; parents (n = 31) participated in a semi-structured interview and completed a demographic survey. Parent and child activity levels were compared using paired t-tests; interviews were analyzed with qualitative content analysis. RESULTS: Although 100% children and 46% parents met physical activity guidelines, parents and children spent most of the day in sedentary behaviors. Parent-reported PA barriers included their long work hours, lack of transportation, and their child's screen-time. CONCLUSION: Addressing barriers and reducing sedentary time could increase PA of rural Latino families.

Greenspace Interventions, Stress and Cortisol: A Scoping Review.

BACKGROUND: Engaging with nature can profoundly impact psychological and physiological health of persons across the lifespan. Greenspace interventions (GSI) encompass a broad range of strategic, nature-based activities for overall health and wellbeing. Within the past 20 years there has been a growing interest in the access to and management of greenspace to mediate the deleterious impact of acute and chronic stress, particularly, physiologic biomarkers of stress such as cortisol. OBJECTIVE: This review aims to describe the impact of greenspace interventions on cortisol, to present the current state of the science on GSIs as they impact cortisol, and to uncover any limitations of current research strategies to best inform future research. METHODS: A scoping methodology was conducted to systematically study this emerging field and inform future research by mapping the literature based on the GSI category, interventional design, cortisol metrics, and subsequent analysis of cortisol. CONCLUSION: Considerable heterogeneity in research design, aim(s), interventional strategy, and cortisol metrics were identified from a total of 18 studies on GSIs and cortisol outcomes. While studies demonstrated a potential for the positive association between GSIs and stress relief, more rigorous research is needed to represent GSIs as an intervention to mitigate risks of stress.

The Interrelationship of Shinrin-Yoku and Spirituality: A Scoping Review.

Background and objectives: Shinrin-yoku (SY; Forest Bathing) is an integrative practice known to improve humans' physiologic and psychologic health and well-being by mindfully using the five human senses while relaxing in natural environments. In addition, it may be effective in enhancing or revealing human spirituality. The World Health Organization defines an individual's well-being as an awareness of one's fullest possible physical, psychologic, social, spiritual, and economic self. Recent evidence suggests that nature promotes spiritual well-being. Hence, the authors performed a scoping review of the literature with regard to the evidence of the interrelationship of SY/nature and spirituality with an aim to identify gaps in knowledge and assist with furthering empirical research. Methods: The PRISMA extension for Scoping Reviews (PRISMA-ScR) methodological approach, presented by Tricco et al., was utilized by searching the electronic databases, CINAHL, Google Scholar, Scopus, PubMed, PsychInfo, and ScienceDirect separately, for authors using key terms shinrin-yoku, forest bathing, nature based therapy, spirituality, health, wellbeing, awe, and wonder. Results: Of the 30 publications, 13 met the eligibility criteria and were included in the synthesis. The authors discovered that, despite the different research methodologies and publications, nature may have a positive effect on human spirituality and, therefore, enriching individuals' well-being. Conclusions: SY is an integrative practice that may enhance or actualize human spirituality. More research is needed to determine the interrelationship of SY and human spirituality in achieving one's fullest possible self.

Shinrin-Yoku (Forest Bathing) and Nature Therapy: A State-of-the-Art Review.

BACKGROUND: Current literature supports the comprehensive health benefits of exposure to nature and green environments on human systems. The aim of this state-of-the-art review is to elucidate empirical research conducted on the physiological and psychological effects of Shinrin-Yoku (or Forest Bathing) in transcontinental Japan and China. Furthermore, we aim to encourage healthcare professionals to conduct longitudinal research in Western cultures regarding the clinically therapeutic effects of Shinrin-Yoku and, for healthcare providers/students to consider practicing Shinrin-Yoku to decrease undue stress and potential burnout. METHODS: A thorough review was conducted to identify research published with an initial open date range and then narrowing the collection to include papers published from 2007 to 2017. Electronic databases (PubMed, PubMed Central, CINAHL, PsycINFO and Scopus) and snowball references were used to cull papers that evaluated the use of Shinrin-Yoku for various populations in diverse settings. RESULTS: From the 127 papers initially culled using the Boolean phrases: "Shinrin-yoku" AND/OR "forest bathing" AND/OR "nature therapy", 64 studies met the inclusion criteria and were included in this summary review and then divided into "physiological," "psychological," "sensory metrics" and "frameworks" sub-groups. CONCLUSIONS: Human health benefits associated with the immersion in nature continue to be currently researched. Longitudinal research, conducted worldwide, is needed to produce new evidence of the relationships associated with Shinrin-Yoku and clinical therapeutic effects. Nature therapy as a health-promotion method and potential universal health model is implicated for the reduction of reported modern-day "stress-state" and "technostress.".
