Engaging with nature to promote health: new directions for nursing research

Nature-based interventions to promote health for people with stress-related illness: An integrative review

BACKGROUND

Stress-related illness is increasing and is a common cause of sick leave. Spending time in nature have a positive effect on health and well-being for instance by reducing stress. Specific programmes with nature-based interventions (NBI) with the intention to involve people in activities in a supportive natural environment have been developed for people with stress-related illness.

AIM

To identify and summarise scientific studies of NBIs to promote health for people with stress-related illness.

METHOD

The design used in this study is integrative literature review. Scientific studies focusing on any type of NBI for people with stress-related illness were sought in Cinahl, PubMed, PsycInfo, AMED and Scopus. In total, 25 studies using both qualitative and quantitative designs were included in the review.

RESULT

The reviewed studies focused on garden or forest interventions. In the majority of the studies, NBIs were performed in groups, including individual activities, and the length of programmes varied. Interventions in natural environments have unique qualities for individualised, meaningful activities and interactions with others in a non-demanding atmosphere. NBIs offer restoration that reduces stress, improves health and well-being and strengthen self-efficacy and work ability. Connectedness with nature support existential reflections and people with stress-related illness can achieve balance in everyday life.

CONCLUSION

In conclusion, NBIs may have advantages to promote health for people with stress-related illness and should therefore be considered as an alternative to those affected. Further research from different perspectives, including nursing, is needed to understand the possibilities of NBIs and how they can be integrated into practice.

Nature-based therapeutics: A collaborative research agenda promoting equitable access and environmental stewardship

BACKGROUND

Given the duration and intensity of the COVID-19 pandemic, with strict emphasis on social distancing, many individuals and families are experiencing social isolation. The need to explore effective strategies for health promotion and wellness is clear.

AIM

The purpose of this report is to highlight evidence supporting the health benefits of nature-based therapeutics and to describe the exploratory and translational research agenda for a nurse-led program entitled RxPLORE^TM: Prescribing Life Outdoors and Real Exploration.

METHODS

Integrative review of the current state of evidence for nature-based therapeutics and operationalisation of a nature-based health promotion framework as the foundation of a PhD-DNP collaborative program of research.

DISCUSSION

Amidst the unfolding crisis of the COVID-19 pandemic, the value of nature-based therapeutics is becoming more widely recognised, as are layers of disparities in access to nature. A nurse-led team proposes a program of research outlining priorities for the translation of current evidence into practice and for the investigation of gaps in the evidence base that will inform future recommendations for nature-based health promotion. The initial population of focus is children and families.

CONCLUSION

Prescribing nature is a strategy to promote health and wellness throughout the lifespan. For all populations to experience the health-promoting benefits of nature, nurses engage community members and collaborate across sectors to advocate for equitable access to nature and environmental stewardship through conservation practices.

Understanding the benefits of horticultural therapy on paediatric patient's well-being during hospitalisation

Purpose

The aim of this study is to undertake a systemic literature review (SLR) of horticultural therapy and to explore whether its inclusion in a healthcare programme can enhance hospitalised children's well-being.

Design/methodology/approach

An empirical study was developed using a mixed methods approach to monitor stakeholders' perceptions of horticultural therapy. Specifically, hospitalised children (N = 31) and their families (N = 21), as well as medical and nursing staff (N = 3), were engaged in the empirical study. Qualitative and quantitative surveys were developed, involving two paediatric units in an Italian hospital.

Findings

The authors’ findings show a significant improvement of children's mood and psycho-physical well-being following horticultural therapy. The authors found positive effects of interactive horticultural therapy on hospitalised paediatric patients and their parents. Parents perceived a positive influence on their mood and found the therapy very beneficial for their children. Qualitative analyses of children's and parents' comments (and related rankings) revealed the helpful support role of horticultural therapy in dealing with the hospitalisation period. There is a very limited number of studies that have inspected co-therapy implementation in paediatric hospitals, and to the best of the authors' knowledge, no study has yet examined the effect of horticultural therapy in such a context. The practice of horticultural therapy with children in health settings has been documented in some Italian hospitals, but its effectiveness has not yet been well established in the literature.

Originality/value

The authors’ findings could provide useful insights to clinicians, health managers and directors in creating and sustaining a successful group co-therapy programme under the managed healthcare system.

Effects of exposure to immersive videos and photo slideshows of forest and urban environments

A large number of studies have demonstrated the benefits of natural environments on people's health and well-being. For people who have limited access to nature (e.g., elderly in nursing homes, hospital patients, or jail inmates), virtual representations may provide an alternative to benefit from the illusion of a natural environment. For this purpose and in most previous studies, conventional photos of nature have been used. Immersive virtual reality (VR) environments, however, can induce a higher sense of presence compared to conventional photos. Whether this higher sense of presence leads to increased positive impacts of virtual nature exposure is the main research question of this study. Therefore, we compared exposure to a forest and an urban virtual environment in terms of their respective impact on mood, stress, physiological reactions, and cognition. The environments were presented via a head-mounted display as (1) conventional photo slideshows or (2) 360[Formula: see text] videos. The results show that the forest environment had a positive effect on cognition and the urban environment disturbed mood regardless of the mode of presentation. In addition, photos of either urban or forest environment were both more effective in reducing physiological arousal compared to immersive 360[Formula: see text] videos.

Nature As Medicine: Mind, Body, and Soil

Editor's Note: Debate over the evidence supporting integrative care interventions not infrequently references the challenges funding research on natural agents and practices that are not patentable. The subject of this column goes to the mother of all such interventions, nature herself. Yet in this case, the authors report an awakening of research that affirms nature's power in health and well-being. This is the eighth commentary through JACM's column partnership with the Osher Collaborative for Integrative Medicine through which we seek to stimulate critical conversations via perspectives from the leaders of the Collaborative's seven prominent academically based integrative centers. The author team came together from three of the centers: David Victorson, PhD, at the Northwestern University Feinberg School of Medicine, Christina Luberto, PhD, at the Harvard Medical School, and Karen Koffler, MD, at the University of Miami Miller School of Medicine. While providing readers an understanding of how to examine nature as medicine, they propose a "goodness of fit" between the precepts of the integrative field and the natural world.-Editor-in-Chief, John Weeks (johnweeks-integrator.com).

Therapeutic gardens as a design approach for optimising the healing environment of patients with Alzheimer's disease and other dementias: A narrative review

PURPOSE

The first half of this paper documents the role of nature in healthcare environments and its impact on wellness, with a particular focus on gardens. The second half presents a scientific evaluation of the role of gardens as a therapeutic intervention to optimise the clinical outcomes in patients with Alzheimer's disease (AD) and dementia, including a review of the innovative application of technologies alongside nature to promote cognitive rehabilitation in this particular patient population.

METHODS

Using search engines such as the Institute for Scientific Information (ISI) Web of Science, PubMed, ProQuest Central, MEDLINE, Scopus and Google Scholar, a relevant literature search on the positive health implications of therapeutic gardens (TG) on AD and dementia patients in the healthcare milieu was conducted.

RESULTS

The health implications of TG for AD and dementia patients span physical, social, psychological and cognitive effects. Virtual reality (VR) technologies that display natural environments also offer positive cognitive outcomes for AD and dementia patients.

CONCLUSION

TG should be used to improve the health and wellbeing of AD and dementia patients, and its application should be extended to other patient populations to promote quicker recovery. Future directions in the design of TG, with a focus on patients with AD and other dementias, is also discussed.

Influence of Social Exchange Relationships on Affective Commitment and Innovative Behavior: Role of Perceived Organizational Support

The current study objective is to investigate how and when leader member exchange (LMX), tie strength, and innovative organizational culture influences employee innovative behavior. In particular, this study uses the social exchange theory to analyze that nurses who demonstrate high affective commitment exhibit a higher level of creativity in the workplace. Based on social exchange theory and perceived organizational support (POS) literature, the current study aims to reveal how perceived organizational support (POS) serves as an imperative mediating process between LMX, tie strength, innovative organizational culture, and employee IB. A questionnaire survey was utilized to collect the data from nurses working in public sector hospitals in Jiangsu province China. A total sample size consists of 325 nurses. Structural equation modeling through AMOS 20 was utilized to analyze the survey data. Results from the structural equation modeling (SEM) analysis indicated that LMX, tie strength, and POS are significantly related to affective commitment and employees’ IB. However, innovative organizational culture has a significant influence on POS and IB, but has no impact on affective commitment. This study covers only public sector hospitals and is limited to Jiangsu province, China. The research could be reproduced in other designated areas in different organizational setups with a bigger sample size to further enhance the understanding of the topic. The key understanding of social exchange theory (SET) is that social relationships can be used appropriately to foster an employee’s IB. It also expands research in the area of LMX, tie strength, innovative organizational culture, and POS as antecedents of affective commitment and IB. This study is a remarkable analysis of LMX, POS, organization culture, commitment, and IB in the Chinese organizational context.

Comparison of the Effects of Benson Muscle Relaxation and Nature Sounds on the Fatigue in Patients With Heart Failure: A Randomized Controlled Clinical Trial

This study was conducted with the aim of comparing the effects of Benson muscle relaxation and nature sounds on fatigue in patients with heart failure. Fatigue and exercise intolerance as prevalent symptoms experienced by patients with heart failure can cause the loss of independence in the activities of daily living. It can also damage self-care and increase dependence to others, which subsequently can reduce the quality of life. This randomized controlled clinical trial was conducted in an urban area of Iran in 2016. Samples were consisted of 105 hospitalized patients with heart failure chosen using a convenience sampling method. They were assigned to relaxation, nature sounds, and control groups using a randomized block design. In addition to routine care, the Benson muscle relaxation and nature sounds groups received interventions in mornings and evenings twice a day for 20 minutes within 3 consecutive days. A 9-item questionnaire was used to collect data regarding fatigue before and after the interventions. Relaxation and nature sounds reduced fatigue in patients with heart failure in comparison to the control group. However, no statistically significant difference was observed between the interventions. Benson muscle relaxation and nature sounds are alternative methods for the reduction of fatigue in patients with heart failure. They are inexpensive and easy to be administered and upon patients' preferences can be used by nurses along with routine nursing interventions.

Health promotion and sustainability programmes in Australia: barriers and enablers to evaluation

In an era characterised by the adverse impacts of climate change and environmental degradation, health promotion programmes are beginning to actively link human health with environmental sustainability imperatives. This paper draws on a study of health promotion and sustainability programmes in Australia, providing insights to evaluation approaches being used and barriers and enablers to these evaluations. The study was based on a multi-strategy research involving both quantitative and qualitative methods. Health promotion practitioners explained through surveys and semi-structured interviews that they focused on five overarching health and sustainability programme types (healthy and sustainable food, active transport, energy efficiency, contact with nature, and capacity building). Various evaluation methods and indicators (health, social, environmental, economic and demographic) were identified as being valuable for monitoring and evaluating health and sustainability programmes. Findings identified several evaluation enablers such as successful community engagement, knowledge of health and sustainability issues and programme champions, whereas barriers included resource constraints and competing interests. This paper highlights the need for ecological models and evaluation tools to support the design and monitoring of health promotion and sustainability programmes.

Nature Contacts

Objective:

This study was designed to ascertain the amount of outdoor, indoor, and indirect nature contact exposures hospital employees have in a workweek.

Background:

Hospital employees have been found particularly vulnerable to work-related stress. Increasing the nature contact exposure for hospital employees can reduce perceived stress; stress-related health behaviors; and stress-related health outcomes from outdoor, indoor, and indirect exposures to nature.

Methods:

Staff on the fourth floor postsurgical unit of a large hospital ( N = 42) were ask to participate in an employee questionnaire “nature contact questionnaire”. This 16-item nature environment questionnaire measures the amount and types of nature contact exposures employees have during a workweek.

Results:

Majority of employees reported few, if any, nature contact exposures, specifically in the area of outdoor nature contacts with limited indoor and indirect contacts. These results indicated that employees on the fourth floor postsurgical floor have limited ability to reduce stress through nature contact exposures which could impact their perceived levels of work stress and stress-related behaviors and health outcomes.

Conclusions:

Nature contact exposures are both a relatively easy and an inexpensive way to improve employee stress. These findings indicate limitations to employees’ exposure to nature contacts. Healthcare environments would benefit from a concerted effort to provide increased outdoor, indoor, and indirect nature contact exposures for employees.

Indoor nature exposure (INE): a health-promotion framework

Engaging in outdoor nature-based spaces has significant positive physiological and psychological health benefits. Although the integration of nature into indoor spaces is rarely considered a health-promoting tool, it may be an effective method for increasing nature engagement in a largely urbanized world. This paper presents an overview of indoor nature exposure (INE) by summarizing the current evidence of INE through the use of a scoping methodology. Results show that INE can be a health-promoting tool through the interaction of nature-based stimuli and individual characteristics (e.g. gender, age). Moreover, the results of the current literature need to be interpreted with consideration to methodological issues, such as the lack of participant characteristics, the issue of exposure realism and little qualitative data to highlight individual experiences. The scoping review process allowed for the summation of results and for a framework to be created in order to better understand how INE is facilitated.

Sustainability in nursing: a concept analysis

AIM

The aim of this study was to describe, explore and explain the concept of sustainability in nursing.

BACKGROUND

Although researchers in nursing and medicine have emphasised the issue of sustainability and health, the concept of sustainability in nursing is undefined and poorly researched. A need exists for theoretical and empirical studies of sustainability in nursing.

DESIGN

Concept analysis as developed by Walker and Avant.

METHOD

Data were derived from dictionaries, international healthcare organisations and literature searches in the CINAHL and MEDLINE databases. Inclusive years for the search ranged from 1990 to 2012. A total of fourteen articles were found that referred to sustainability in nursing.

RESULTS

Sustainability in nursing involves six defining attributes: ecology, environment, future, globalism, holism and maintenance. Antecedents of sustainability require climate change, environmental impact and awareness, confidence in the future, responsibility and a willingness to change. Consequences of sustainability in nursing include education in the areas of ecology, environment and sustainable development as well as sustainability as a part of nursing academic programs and in the description of the academic subject of nursing. Sustainability should also be part of national and international healthcare organisations. The concept was clarified herein by giving it a definition.

CONCLUSION

Sustainability in nursing was explored and found to contribute to sustainable development, with the ultimate goal of maintaining an environment that does not harm current and future generations' opportunities for good health. This concept analysis provides recommendations for the healthcare sector to incorporate sustainability and provides recommendations for future research.

The beach as a setting for families' health promotion: a qualitative study with parents and children living in coastal regions in Southwest England

This study explores the neglected issue of how families engage with beach environments in their local areas and use them in health promoting ways. Fifteen families with children aged 8-11 years living in coastal regions in Southwest England participated in individual semi-structured interviews. The findings indicate that beaches encouraged families to be physically active. Although families valued the opportunities for physical activity and active play afforded by beaches, the key health benefits emphasised were psychological, including experiencing fun, stress relief and engagement with nature. Increased social and family interaction was also highlighted as benefits. Despite perceiving health benefits, not all families regularly visited the beach. Barriers to visits included parents having limited time, cost of parking, lack of car access and cold weather. Parents played a key role in enabling visits by choosing to share these environments with their children. The social dimension of visits also encouraged families to make regular trips. The findings support the use of beach environments to promote families' health and wellbeing and positive relationships with nature.

What are the benefits of interacting with nature?

There is mounting empirical evidence that interacting with nature delivers measurable benefits to people. Reviews of this topic have generally focused on a specific type of benefit, been limited to a single discipline, or covered the benefits delivered from a particular type of interaction. Here we construct novel typologies of the settings, interactions and potential benefits of people-nature experiences, and use these to organise an assessment of the benefits of interacting with nature. We discover that evidence for the benefits of interacting with nature is geographically biased towards high latitudes and Western societies, potentially contributing to a focus on certain types of settings and benefits. Social scientists have been the most active researchers in this field. Contributions from ecologists are few in number, perhaps hindering the identification of key ecological features of the natural environment that deliver human benefits. Although many types of benefits have been studied, benefits to physical health, cognitive performance and psychological well-being have received much more attention than the social or spiritual benefits of interacting with nature, despite the potential for important consequences arising from the latter. The evidence for most benefits is correlational, and although there are several experimental studies, little as yet is known about the mechanisms that are important for delivering these benefits. For example, we do not know which characteristics of natural settings (e.g., biodiversity, level of disturbance, proximity, accessibility) are most important for triggering a beneficial interaction, and how these characteristics vary in importance among cultures, geographic regions and socio-economic groups. These are key directions for future research if we are to design landscapes that promote high quality interactions between people and nature in a rapidly urbanising world.

Developing an exploratory framework linking Australian Aboriginal peoples' connection to country and concepts of wellbeing

Aboriginal people across Australia suffer significant health inequalities compared with the non-Indigenous population. Evidence indicates that inroads can be made to reduce these inequalities by better understanding social and cultural determinants of health, applying holistic notions of health and developing less rigid definitions of wellbeing. The following article draws on qualitative research on Victorian Aboriginal peoples’ relationship to their traditional land (known as Country) and its link to wellbeing, in an attempt to tackle this. Concepts of wellbeing, Country and nature have also been reviewed to gain an understanding of this relationship. An exploratory framework has been developed to understand this phenomenon focusing on positive (e.g., ancestry and partnerships) and negative (e.g., destruction of Country and racism) factors contributing to Aboriginal peoples’ health. The outcome is an explanation of how Country is a fundamental component of Aboriginal Victorian peoples’ wellbeing and the framework articulates the forces that impact positively and negatively on this duality. This review is critical to improving not only Aboriginal peoples’ health but also the capacity of all humanity to deal with environmental issues like disconnection from nature and urbanisation.

People with dementia and the hospital environment: the view of patients and family carers

BACKGROUND

A metropolitan geriatric evaluation and management (GEM) facility in Australia was undergoing expansion, and consideration for the needs of individuals with dementia and their family carers was identified as important in planning the new facility. Existing literature revealed that people in hospital value privacy, minimal noise, family amenities and homeliness, but these findings did not consider the perspectives of the person with dementia specifically.

AIM

The aim was to elicit the perspectives of current inpatients with dementia, and their family carers, about the environment/design features that they believe are necessary for people with dementia, and their family carers.

METHOD AND DESIGN

This qualitative study utilised in-depth semi-structured interviews to obtain information from current inpatients with dementia and their family carers.

RESULTS

Participants described how the care received was more important than the physical environment; however, participants also valued homeliness, privacy for the patient and for conversations, a shared space without a television and a connection to the outside. Participants described how accommodating carers, providing quiet spaces and appropriate amenities were also important.

CONCLUSIONS

While participants valued care over the physical surroundings, they also offered valuable information about their experience in the ward environment. Despite cognitive difficulties, people with dementia were able to provide useful information about the environment within which they were being cared.

IMPLICATIONS FOR PRACTICE

Consumer opinions about hospital design/environment should be considered as an important source of data. Privacy and personal space for people with dementia and their family carers, a connection with the outside environment , and the needs of carers and visitors are all important considerations when designing healthcare environments.

A prospective study of group cohesiveness in therapeutic horticulture for clinical depression

This study aimed to assess changes in psychological distress and social participation in adults diagnosed with clinical depression during and after participating in a therapeutic horticulture programme, and to investigate if the changes covaried with levels of group cohesiveness during the intervention. An intervention with a single-group design was repeated with different samples in successive years (pooled n = 46). In each year, five groups of 3-7 participants went through the intervention. Data were collected before, twice during, and immediately after a 12-week therapeutic horticulture programme, as well as at 3-months' follow up. Mental health assessments included the Beck Depression Inventory, the State Subscale of Spielberger State-Trait Anxiety Inventory, the Positive Affect Scale from the Positive and Negative Affect Scale, the Perceived Stress Scale, and the Therapeutic Factors Inventory-Cohesiveness Scale. The analysis of the pooled data confirmed significant beneficial change in all mental health variables during the intervention. Change from baseline in depression severity persisted at 3-months' follow up. Increased social activity after the intervention was reported for 38% of the participants. The groups quickly established strong cohesiveness, and this continued to increase during the intervention. The average level of group cohesiveness correlated positively, but not significantly, with change in all mental health outcome variables.

A prospective study of existential issues in therapeutic horticulture for clinical depression

Two studies with single-group design (Study 1 N = 18, Study 2 N = 28) addressed whether horticultural activities ameliorate depression severity and existential issues. Measures were obtained before and after a 12-week therapeutic horticulture program and at 3-month follow-up. In both studies, depression severity declined significantly during the intervention and remained low at the follow-up. In both studies the existential outcomes did not change significantly; however, the change that did occur during the intervention correlated (rho > .43) with change in depression severity. Participants' open-ended accounts described the therapeutic horticulture experience as meaningful and influential for their view of life.

Engaging with nature to promote health: bridging research silos to examine the evidence

While there is considerable research on environmental contamination and degradation, there is equally credible evidence on the healthful qualities of the environment. Being in and caring for nature can be health promoting for individuals, families, communities, ecosystems and the planet. In this paper, we use a conceptual model for nature-based health promotion and a socio-ecological model of health promotion to guide the scope, organization and critique of relevant literature on nature-based health promotion in several fields and generate recommendations for practice, policy and research. We conclude that participatory community-based research is needed to build local knowledge and create systemic change in practice and policy to support healthy living for people and the planet.

Therapeutic horticulture in clinical depression: a prospective study of active components

AIM

This paper is a report of a study conducted to assess change in depression severity, perceived attentional capacity and rumination (brooding) in individuals with clinical depression during a therapeutic horticulture programme and to investigate if the changes were mediated by experiences of being away and fascination.

BACKGROUND

Individuals with clinical depression suffer from distortion of attention and rumination. Interventions can help to disrupt maladaptive rumination and promote restoration of depleted attentional capacity.

METHOD

A single-group study was conducted with a convenience sample of 28 people with clinical depression in 2009. Data were collected before, twice during, and immediately after a 12-week therapeutic horticulture programme, and at 3-month follow-up. Assessment instruments were the Beck Depression Inventory, Attentional Function Index, Brooding Scale, and Being Away and Fascination subscales from the Perceived Restorativeness Scale.

FINDINGS

Mean Beck Depression Inventory scores declined by 4.5 points during the intervention (F = 5.49, P = 0.002). The decline was clinically relevant for 50% of participants. Attentional Function Index scores increased (F = 4.14, P = 0.009), while Brooding scores decreased (F = 4.51, P = 0.015). The changes in Beck Depression Inventory and Attentional Function Index scores were mediated by increases in Being Away and Fascination, and decline in Beck Depression Inventory scores was also mediated by decline in Brooding. Participants maintained their improvements in Beck Depression Inventory scores at 3-month follow-up.

CONCLUSION

Being away and fascination appear to work as active components in a therapeutic horticulture intervention for clinical depression.
