Salutogenic Effects of the Environment: Review of Health Protective Effects of Nature and Daylight

Assessing the impact of glazing and window shade systems on view clarity

Windows provide access to daylight and outdoor views, influencing building design. Various glazing and window shade materials are used to mitigate glare, overheating and privacy issues, and they affect view clarity. Among them, we evaluated the effect of window films, electrochromic (EC) glass, and fabric shades on view clarity. We conducted an experiment with 50 participants using visual tests adapted from clinical vision tests (visual acuity, contrast sensitivity, color sensitivity) and images displayed on a computer monitor in a controlled laboratory. Window films and EC glass tints outperformed fabric shades in visual acuity, contrast sensitivity and view satisfaction with the exception of the darkest EC tint state and dark grey VLT 3% shade for color sensitivity and view satisfaction. The EC tints pose internal reflection issues and fabric shades are preferred for visual privacy. Window films and EC glass hinder participants' blue-green color discrimination while fabric shades also decrease red-yellow color discrimination. Visual acuity predicts view satisfaction and contrast sensitivity is the strongest predictor for visual privacy. Generally, higher visible light transmittance and lower solar reflectance (darker color) enhance human visual performance. The proposed workflow provides an experimental procedure, identifies the primary variables and establishes a predictive framework for assessing view clarity of fenestration.

Does daily nature exposure enhance children's self-worth and positive feelings? An experience sampling study

Previous studies suggest that nature exposure has positive effects on children's cognitive performance and well-being . However, inconsistent evidence was found for effects on children's self-worth and feelings. These inconsistencies may be resolved by studying children's actual exposure and experiences in detail. Therefore, in the present study, we investigated the effect of daily nature exposure on children's self-worth and feelings with an experience sampling method. Sixty-six third graders (29 girls, mean age = 9.04 years) participated two to three times per day consecutively for 9 days. The resulting 1199 observations were analyzed and showed that when exposed to nature children reported significantly higher self-worth and positive feelings than when not exposed to nature, with baseline levels controlled. Positive feelings played mediating roles in relationships between nature exposure and children's self-worth. Our study strengthens the evidence on beneficial effects of nature on children's well-being. The mechanisms involved in this effect are discussed.

Supporting and implementing the beneficial parts of the exposome: The environment can be the problem, but it can also be the solution

In 2005, Christopher P. Wild introduced the exposome concept, encompassing the biochemical changes in the organism in response to the totality of all environmental exposures throughout the entire lifespan and their association with health outcomes. The exposome concept also aimed at to completing the genome, that describes the genetic predisposition as a determinant of disease and death as well as potential targets of intervention. The exposome can be subdivided into multiple pollutomes related to specific chemical and physical pollutants (or other forms of environmental risks), periods of life (infancy, childhood, adolescence, adulthood, and old age) or geographical locations. While exposome research and, in general, health research of the last decades has predominantly focused on what factors contribute to and initiate morbidity and mortality, little is done on factors that will help to develop, maintain, or even increase human health. We want to contribute to this reorientation by supporting and implementing the beneficial exposome, comprising all environmental exposures with the potential to promote health.

Objective greenness, connectedness to nature and sunlight levels towards perceived restorativeness in urban nature

The beneficial effect of exposure to nature and immersion in natural environments on perceived well-being is well established. Nevertheless, we acknowledge an emerging need to disentangle the role of specific environmental features from individual factors that encourage a positive person-environment interaction. This study aimed at evaluating the associations between four buffer distances of greenness and dimensions of perceived restorativeness, with connectedness towards nature (CTN) as a confounder variable, in a sample of 312 visitors to a large urban park. Variables investigating ecosystem services (ES, e.g., thermal comfort) were included as covariates. Results revealed differentiated effects of greenness level, sunlight intensity, and connectedness to nature in the pathways towards dimensions of restorativeness. Greenness level at 300 m was associated with Fascination, Scope, and Being Away, while at 500 m was associated with Coherence, Scope, and Being Away. ES was found to be associated with Coherence, while CTN with the other three dimensions of restorativeness. The moderating effect of sunlight level in the relationship between NDVI buffer distances and the total score of perceived restorativeness was also confirmed. The present work is intended to offer insights on the interplay between environmental features and individual differences for implications in several contexts, including the opportunity to develop tailor-made planning for urban forestry.

Do Mental Health Changes in Nature Co-occur with Changes in Heartrate Variability and Executive Functioning? A Systematic Review

PURPOSE OF REVIEW

Given the global burden of mental health issues, new solutions are needed to promote mental health. Nature exposure represents a promising option to promote mental health, but the mechanisms are poorly understood. Recent frameworks have argued that changes in mental health in nature are caused by activity changes in the vagus nerve, which connects the heart and the brain, and that these changes also improve executive functioning (EF) abilities. This suggests that changes in mental health symptomology in nature should be accompanied by changes in vagus nerve activity, as well as changes in executive functioning. Yet, little work has systematically examined co-variation of these outcomes in empirical studies. The present manuscript systematically examines whether changes in mental health in nature are accompanied by changes in vagus nerve activity (approximated by heartrate variability) and changes in executive functioning.

RECENT FINDINGS

There is compelling evidence that spending time in nature can increase heartrate variability, improve mental health, and improve executive functioning. However, despite strong theoretical claims that these three outcomes should be linked after spending time in nature settings, few studies directly examine such co-occurrence. The study systematically examines whether studies that considered both mental health and executive functioning (n = 6) showed co-occurring effects in response to nature exposure. Similarly, the study also considers if studies examining mental health and heartrate variability (n = 6) showed similarly directional effects following nature exposure. This systematic review concludes with discussion about the limited number of studies (n =1) that include all three measures. We find mixed results of co-occurrence with these variables, suggesting that the relationship between these three constructs in nature may be more nuanced than current theory suggests. Perhaps more importantly, our results demonstrate that there is very little existing work linking changes in mental health to changes in EF and vagal tone. We conclude with justification for why it may be beneficial for researchers to include all three metrics as well as guidance on how to do so.

Associations Between Primary Residence and Mental Health in Global Marginalized Populations

Scholars suggest that marginalized people in non-urban areas experience higher distress levels and fewer psychosocial resources than in urban areas. Researchers have yet to test whether precise proximity to urban centers is associated with mental health for marginalized populations. We recruited 1733 people who reported living in 45 different countries. Participants entered their home locations and completed measures of anxiety, depression, social support, and resilience. Regression and thematic analyses were used to determine what role distance from legislative and urban centers may play in mental health when marginalized people were disaggregated. Greater distance from legislative center predicted higher anxiety and resilience. Greater distance from urban center also predicted more resilience. Thematic analyses yielded five categories (e.g., safety, connection) that further illustrated the impact of geographic location on health. Implications for community mental health are discussed including the need to better understand and further expand resilience in rural areas.

Informal antidepressant strategies for nursing home residents: two group concept mapping studies

OBJECTIVES

To identify and structure potential informal antidepressant strategies that can be used in daily practice for nursing home residents alongside formal treatments.

METHODS

In a first Group Concept Mapping study, residents, relatives, and professional caregivers (N = 124) brainstormed on strategies residents could use to prevent or alleviate depression. In a second study, the same participants (N = 110) reported strategies for use by others. Furthermore, participants rated the expected effectiveness and feasibility of the suggested strategies. Simultaneously, all strategies were sorted by experts and clustered using multidimensional scaling and hierarchical cluster analysis.

RESULTS

Six clusters emerged for strategies by residents themselves and five clusters for strategies by others. For residents' strategies, the clusters Being socially connected and Participating in activities were perceived as most effective, as was the cluster Offering personal attention for strategies by others. Participants perceived Creating a healthy living environment as the most feasible cluster executed by residents. Within strategies by others, the clusters Offering personal attention, Using positive treatment/approach, and Using or adapting the physical environment were perceived as the most feasible.

CONCLUSION

The results indicated the importance of social connectedness, a personalized and positive approach by significant others, and tailored activity programs. The results also suggest that adaptations to the physical environment within nursing homes may be an easy applicable strategy to prevent or alleviate depression in residents. Although more research is needed, these findings may guide daily practice and the development of interventions that include informal strategies.

Neighborhood influences on the development of self-regulation among children of color living in historically disinvested neighborhoods: Moderators and mediating mechanisms

We present a conceptual model of the ways in which built and social environments shape the development of self-regulation in early childhood. Importantly, in centering children of color growing up in historically disinvested neighborhoods, we first describe how systemic structures of racism and social stratification have shaped neighborhood built and social environment features. We then present evidence linking these neighborhood features to children's development of self-regulation. Furthermore, we take a multilevel approach to examining three potential pathways linking neighborhood contexts to self-regulation: school environment and resources, home environment and resources, and child health behaviors. Finally, we consider how racial-ethnic-cultural strengths and multilevel interventions have the potential to buffer children's development of self-regulation in disinvested neighborhood contexts. Advancing multilevel approaches to understand the development of self-regulation among children of color living in historically disinvested neighborhoods is an important step in efforts to promote equity in health and education.

Satisfaction with activity-support and physical home-workspace characteristics in relation to mental health during the COVID-19 pandemic

Previous research indicates that employees' mental health might be influenced by their satisfaction with physical office characteristics, such as noise, daylight, and ventilation. However, similar research on mental health in relation to working from home (WFH) is limited. Therefore, this study aimed to identify the relationships between satisfaction with physical home workspace characteristics and support of work activities and mental health while WFH during the COVID-19 pandemic. Relationships were analysed using a path analysis approach, based on a sample of 1219 office workers, who had to work fully from home. The internal relationships between the ten considered mental health variables were also studied. Results showed that satisfaction with daylight, artificial light, greenery, and views outside were directly related to one of the mental health variables and indirectly to several others. Surprisingly, satisfaction with temperature, noise, ventilation, and air quality did not seem to play a role at the home workplace. In addition, unlike at the office, personal characteristics did not relate to workspace satisfaction nor perceived support of activities at home. Furthermore, all mental health variables were related to at least one other mental health variable. Workplace managers could use these insights to formulate recommendations for employees on how to design their home-workspace.

A Meta-Analysis of Emotional Evidence for the Biophilia Hypothesis and Implications for Biophilic Design

The biophilia hypothesis posits an innate biological and genetic connection between human and nature, including an emotional dimension to this connection. Biophilic design builds on this hypothesis in an attempt to design human-nature connections into the built environment. This article builds on this theoretical framework through a meta-analysis of experimental studies on the emotional impacts of human exposure to natural and urban environments. A total of 49 studies were identified, with a combined sample size of 3,201 participants. The primary findings indicated that exposure to natural environments had a medium to large effect on both increasing positive affect and decreasing negative affect. This finding supported the anticipated emotional dimension of the biophilia hypothesis and lends credibility to biophilic design theory. Evidence was revealed in support of the affective/arousal response model. Immersion in environments indicated a larger effect size than laboratory simulation of environments. Methodological recommendations for future experimental research were few, however the Positive and Negative Affect Schedule (PANAS) outcome measure was recommended as a measure of both positive and negative affect for further studies. A combination measurement of stress related outcome variables was proposed to further explore the affective/arousal response model and its potential relationship to the biophilia hypothesis. The meta-analysis provides evidence for fundamental theories regarding human-nature connection, while revealing gaps in current knowledge.

Urban Green Parks for Long-Term Subjective Well-Being: Empirical Relationships between Personal Characteristics, Park Characteristics, Park Use, Sense of Place, and Satisfaction with Life in The Netherlands

As our living environment is becoming increasingly urbanized, this puts the livability, health, and quality of life in cities under pressure. Due to the urbanization process, urban green spaces are under threat of becoming scarce, while it is recognized that these green spaces can positively contribute to the subjective well-being of citizens. It is thus important to maximize the use and benefits derived from green spaces by designing them as positively experienced places. The aim of this research is to gain more empirical insights on the relationships between personal and park characteristics, park use behavior, sense of place, and park visitors’ long-term subjective well-being (i.e., life satisfaction). An online questionnaire was administered to participants in two medium-sized cities in The Netherlands, namely Eindhoven and ‘s-Hertogenbosch. Data were analyzed using a structural equation model. The results of this study show that the appreciation of facilities and the absence of disturbances positively influence the use and sense of place of a park. Furthermore, the findings show that sense of place has a positive influence on life satisfaction. The findings can be used by designers and policy-makers as guidelines to improve existing parks or to design new parks that support the subjective well-being of individuals in The Netherlands.

An Exploration of How Biophilic Attributes on Campuses Might Support Student Connectedness to Nature, Others, and Self

University Campuses remain important settings for nurturing and supporting student health and quality of life (QoL). Research shows the health benefits of nature experiences may be facilitated by campus spaces and activities that afford connectedness. Connectedness to nature, others, and self may allow students to cope with mental fatigue, stress, and a constant need for restoration. Despite recent encouraging trends, we still lack an integrative conceptual framework to describe the mechanisms involved in achieving connectedness for making recommendations for campus design. In this conceptual review, we examine students' connectedness in campus settings in relation to biophilic elements and attributes. We aim to understand how both direct and indirect pursuits in nature and also place-based experiences on campus foster connectedness and consequently impact students' health and QoL. Our analysis shows that connectedness seen through the lens of Kellert's biophilic design principles and aided by Alexander's pattern language provides a relational and long-term perspective on recommending strategies for connecting students to nature, to others, and to themselves in campus settings.

Oceans and society: feedbacks between ocean and human health

The concentration of human population along coastlines has far-reaching effects on ocean and societal health. The oceans provide benefits to humans such as food, coastal protection and improved mental well-being, but can also impact negatively via natural disasters. At the same time, humans influence ocean health, for example, via coastal development or through environmental stewardship. Given the strong feedbacks between ocean and human health there is a need to promote desirable interactions, while minimising undesirable interactions. To this end, we articulate two scenarios for 2030. First, Business-as-Usual, named 'Command and (out of) Control', focuses on the anticipated future based on our current trajectory. Second, a more sustainable scenario called 'Living and Connecting', emphasises the development of interactions between oceans and society consistent with achieving the Sustainable Development Goals. We describe a potential pathway to achieving the 'Living and Connecting' scenario, centred on improving marine citizenship, achieving a more equitable distribution of power among stakeholders, and more equitable access to resources and opportunities. The constituent actions of this pathway can be categorised into four groups: (i) improved approaches to science and health communication that account for society's diverse values, beliefs and worldviews, (ii) a shift towards more trusted relationships among stakeholders to enable two-way knowledge exchange, (iii) economic incentives that encourage behavioural changes necessary for achieving desired sustainability outcomes, and (iv) stronger regulations that simultaneously focus on ocean and human health. We contend that these changes will provide improved outcomes for both oceans and society over the United Nations Decade of Ocean Science.

Powered by virtual realities: promoting emotional recovery through technology-based recovery interventions

Previous research indicates that short work breaks in nature can facilitate emotional recovery, but during a workday nature is not always accessible. We conducted two intervention studies (N = 51; N = 101) applying virtual reality technology in a short work break and examined the effect of the degree of immersion into nature and the type of nature (stimulating vs. calming) on the restorative experience and, in turn, on affective states. The results revealed that high immersion promotes being away and perceived fascination. Being away mediated the effect of high immersion on increased positive and decreased negative affect. Perceived fascination mediated the effect of stimulating nature on increased positive affect in both studies and decreased negative affect in Study 2. The present research highlights the unique benefits of virtual realities, degrees of immersion and different types of nature for recovery interventions in organisations.Practitioner Summary: Integrating virtual realities into the work environment is an emerging topic. The present research demonstrates that a short technology-based intervention via virtual reality enhances emotional recovery. The results provide interesting possibilities for the design of work breaks in situations where nature is not within reach or not accessible.

Exploring Intraindividual Profiles for Home Buildings Based on Architectural Compositional Elements and Psychological Health Factors: A Transdisciplinary Approach

Based on the transactional and salutogenic perspectives, we explored individual profiles that integrate psychosocial factors and compositional elements of the built home environment. Adults with different socio-demographic characteristics completed several self-report measures on psychological factors (personality traits, self-efficacy, mental health, and happiness) and architectural elements constituting the ideal home environment. Adopting an individual-centered perspective, three distinct intra-individual psycho-architectural (person-environment) profiles were found with different compositional preferences and psychosocial characteristics in terms of functioning, health, and well-being: endopathic (characterized by higher levels of psychosocial resources and well-being indicating a highly adapted and successful profile, and architectural preferences corresponding to their identities and experiences—expression through spaces), assimilative (characterized by average levels in all regulatory parameters indicating moderately adaptive individuals, and architectural preferences of spaces created in interactive processes—introjection of spaces), and additive individuals (characterized by a comparatively dysfunctional, poorer psychosocial profile, and architectural preferences in line with provoking a restorative effect—change with spaces). An awareness of the psychosocial features of the users for whom the homes are built can help in designing spaces to inhabit that are adapted to them for an enhancement of their overall well-being. Therefore, a better understanding of the interconnections between psychology and architecture will help in designing healthy spaces.

Negative social jetlag - Special consideration of leisure activities and evidence from birdwatchers

Birdwatching (birding) is a nature-based recreational activity, often including arising early in the morning. In the present study, we tested the effect of a negative social jetlag (SJL) in birders. Negative SJL implies that people have an even earlier sleep-wake rhythm on free days or weekends. As birds' activities start before or shortly after sunrise, especially during spring and early summer, birdwatchers follow this diurnal pattern. Further, birders are not homogeneous and vary greatly in recreational specialisation. The study was based on an online survey with 2,404 birdwatchers (55% male) who responded to questions about their sleep-wake times and about their birding activities. Birders show the same differences between weekdays and weekends/free days sleep like most other people. However, birdwatching days started earlier than weekdays (14 min) and lasted longer. Thus, birdwatching days are shifted towards an earlier sleep-wake rhythm in total. Birdwatchers experience a sleep curtailment during birding. Instead of sleeping ~30 min longer on weekends, they arise ~15 min earlier, summing up to a sleep reduction of about ~45 min compared to a regular weekend. The more psychologically committed birders are, the less they sleep, the earlier they arise, and the earlier is their midpoint of sleep on birdwatching days; meaning that highly specialised birders shift their sleep-wake rhythm to an earlier time compared to their regular weekend, and even their weekday sleep. Thus, birders may suffer more from the short- and long-term consequences of negative SJL. The results might stand representatively for other nature-related leisure activities.

Enhancing Adolescent Girls' Well-Being in the Arctic-Finding What Motivates Spending Time in Nature

Background: According to previous studies, the natural environment positively influences well-being, including that of adolescent girls. However, knowledge is lacking on what motivates adolescent girls to spend time in nature. A secondary analysis of qualitative data was conducted employing three preexisting sets of interview data that had formed the basis of previously published research reports. A novel perspective on what motivates adolescent girls in the Arctic to spend time in nature was uncovered—a finding that previous articles have not reported. Aim: The aim was to describe what motivates adolescent girls in the Arctic to spend time in nature. Methods: The participants were adolescent girls aged 13 to 16 living in the province of Finnish Lapland. The girls wrote about well-being (n = 117) and were interviewed (n = 19) about the meaning of seasonal changes, nature and animals’ influence on well-being. Also, five focus group interviews (n = 17) were held. The materials were analyzed by inductive content analysis. Results: After the secondary analysis, three generic categories were found: (1) wanting to have pleasant emotions, (2) the possibility of participating in activities and (3) a desire to feel better. The main category of “need to experience positive sensations” was formed. Conclusion: Based on these results, through personalized guidance and advice, it is possible to strengthen adolescent girls’ willingness to spend time in nature.

"Shedding Light on Light": A Review on the Effects on Mental Health of Exposure to Optical Radiation

In relation to human health and functioning, light, or more specifically optical radiation, plays many roles, beyond allowing vision. These may be summarized as: regulation of circadian rhythms; consequences of direct exposure to the skin; and more indirect effects on well-being and functioning, also related to lifestyle and contact with natural and urban environments. Impact on mental health is relevant for any of these specifications and supports a clinical use of this knowledge for the treatment of psychiatric conditions, such as depression or anxiety, somatic symptom disorder, and others, with reference to light therapy in particular. The scope of this narrative review is to provide a summary of recent findings and evidence on the regulating functions of light on human beings’ biology, with a specific focus on mental health, its prevention and care.

From Fable to Reality at Parkland Hospital: The Impact of Evidence-Based Design Strategies on Patient Safety, Healing, and Satisfaction in an Adult Inpatient Environment

OBJECTIVE

This research aimed to evaluate the quantitative effects of new hospital design on adult inpatient outcomes.

BACKGROUND

Tenets of evidence-based healthcare design, notably single-patient acuity-adaptable and same-handed rooms, decentralized nursing stations, onstage offstage layout, and access to nature were expected to promote patient healing and increase patient satisfaction, while decreasing adverse events.

METHODS

Patient healing was operationalized through length of stay (LOS) and patient safety through three adverse events: falls, hospital-acquired infections (HAI), and medication-related events. Standard patient surveys captured patient satisfaction. Patient records from 2013 through 2017 allowed for equivalent time periods surrounding the move to the new hospital in August 2015. Stratified by hospital division where significant, pre/post comparisons utilized proportional hazards or logistic regression models as appropriate; interrupted time series analyses afforded longitudinal interpretations.

RESULTS

Observed higher postmove LOS was due to previously increasing trends, not increases after the move. In surgical and trauma units, a constant increase in falls was unaffected by the move. Medication events decreased consistently over time; medication events with harm dropped significantly after the move. No change in HAI was found. Significant improvement on most relevant patient satisfaction items occurred after the move. Call button response decreased immediately after the move but subsequently improved.

CONCLUSION

Results did not clearly indicate a net change in adult inpatient outcomes of healing and safety due to the hospital design. There was evidence that the new hospital improved patient satisfaction outcomes related to the environment, including comfort, noise, temperature, and aesthetics.

Effects of vitamin D on mood and sleep in the healthy population: Interpretations from the serotonergic pathway

Vitamin D insufficiency is common in the healthy population. Recent insights addressed the role of vitamin D in serotonin and melatonin regulation, suggesting that increasing vitamin D status may be helpful for improving mood and sleep. This literature review covers the current state of evidence regarding potential effects of vitamin D on mood and sleep indicators in healthy people. In total, 11 observational studies were found for sleep, and 54 studies on mood (including ten RCTs). These studies revealed mixed results for both sleep and mood. The findings were interpreted based on the previously proposed serotonergic pathway of vitamin D. Implications and challenges for future research regarding the timing of blood sampling, timing and dosage of supplement intake and investigating the response dynamics are discussed.

ADHD 24/7: Circadian clock genes, chronotherapy and sleep/wake cycle insufficiencies in ADHD

Objectives: The current paper addresses the evidence for circadian clock characteristics associated with attention-deficit hyperactivity disorder (ADHD), and possible therapeutic approaches based on chronomodulation through bright light (BL) therapy.Methods: We review the data reported in ADHD on genetic risk factors for phase-delayed circadian rhythms and on the role of photic input in circadian re-alignment.Results: Single nucleotide polymorphisms in circadian genes were recently associated with core ADHD symptoms, increased evening-orientation and frequent sleep problems. Additionally, alterations in exposure and response to photic input may underlie circadian problems in ADHD. BL therapy was shown to be effective for re-alignment of circadian physiology toward morningness, reducing sleep disturbances and bringing overall improvement in ADHD symptoms. The susceptibility of the circadian system to phase shift by timed BL exposure may have broad cost-effective potential implications for the treatment of ADHD.Conclusions: We conclude that further research of circadian function in ADHD should focus on detection of genetic markers (e.g., using human skin fibroblasts) and development of BL-based therapeutic interventions.

The mobilities of care in later life: exploring the relationship between caring and mobility in the lives of older people

There has been a renewed call for a revaluing of informal caring in order to counter the way that caring is undervalued, taken for granted and invisible. Travel is one area where a detailed critique of this issue has emerged with the concept of ‘mobility of care’, however, this concept has only been applied in relation to younger age groups, and our understanding of mobilities of care in later life remains underdeveloped. By ‘mobilities of care’ we mean journeys made for the purpose of giving and receiving informal care and support. This paper draws on the mobility narratives of 99 older people (aged 55 and above) living in three locations in the North of England who participated in a two-year qualitative longitudinal study that explored the inter-play between mobility, wellbeing and life transitions. We focused on the experience of managing life transitions rather than assume that chronology per se determines wellbeing. Narratives of ageing emphasise the importance of getting out and about, and being socially connected active citizens. Our study demonstrates that for many older people getting out and about is not for leisure or utility purposes but to give support and care. As such, these journeys have a particular significance in the lives of older people and in the construction of roles, meaning and identity in later life.

Physical Fitness as Part of the Health and Well-Being of Students Participating in Physical Education Lessons Indoors and Outdoors

The analysis of existing information on physical activity and fitness as elements of health and well-being reveals that they are achieved particularly effectively in contact with nature. Physical education lessons outdoors, as a form of healthy training, have been performed in numerous countries for years, providing a response to the traditional indoor model of this kind of education. The purpose of this paper is to clarify the relationship between the participation of students in outdoor and indoor lesson activities and the change in their physical fitness. 220 students participated in an experimental study. The experimental group, which did exercise usually in open spaces, included 49 boys and 54 girls. The control group, which exercised inside school, consisted of 63 boys and 54 girls. The study period lasted two years and involved the fifth and sixth form of primary school. Experimental group subjects were 11.26 years old (±0.32) during the initial test, and the control group individuals were 11.28 years (±0.32). During the final test, the average ages of experimental group subjects was 12.96 years (±0.32), and 12.98 years (±0.32) in the control group. The International Physical Activity Test was applied in the study. The differences between the levels of particular components of physical fitness were not statistically significant during the initial measurement (p-values ranged from p = 0.340 to p = 0.884). After two years of outdoor physical education lessons, there was revealed a considerable increase in the speed, jumping ability, and aerobic endurance of the students. Statistically significant differences were observed in these three tests, including running speed (p = 0.001), legs power (p = 0.001), and endurance (p = 0.000). The findings encourage one to continue pedagogical experiments regarding physical activity in outdoor natural environments.

Improved Wellbeing for Both Caretakers and Users from A Zoo-Related Nature Based Intervention-A Study at Nordens Ark Zoo, Sweden

Nature-based interventions have been proposed to promote physical and mental health and give stress reduction. Little attention has been given to the potential of zoos for human health and wellbeing. A disadvantaged group in Sweden regarding access to nature are individuals with disabilities who consequently do not have the same access to these health benefits as other groups. To increase awareness and knowledge regarding spending time in nature and with animals, courses directed at caretakers for persons with disabilities and their users were held at Nordens Ark, a zoo in Sweden. To explore if the courses had led to increased nature activities, and if participating in the courses had affected caretakers' and their users' health and wellbeing, questionnaires and interviews for evaluating the courses were used. The results showed improved quality in nature visits because of course participation as well as positive effects for the wellbeing, sustainability for the caregivers and users in their working lives, and relationships were positively affected. The conclusion from this study is that nature and animal-based education should be more frequent to provide opportunities for a disadvantaged group to have the positive effects of nature of which most other groups have obvious access to.

E-MOVIE - Experimental MOVies for Induction of Emotions in neuroscience: An innovative film database with normative data and sex differences

The need for a validated set of emotional clips to elicit emotions in more ecological experiments is increasing. Here we present the validation of a new database of emotional films, named E-MOVIE, which includes, in this first validation phase, 39 excerpts arranged in six categories, three negative (Fear, Sadness and Compassion), two positive (Erotic and Scenery) and a Neutral category. Notably, Compassion and Scenery are new in the field as they were not included in other databases. The clips in E-MOVIE are characterized by homogenous durations of approximately two minutes, which make them suitable for psychophysiological research. In order to study the affective profile prompted by each category 174 participants (112 women) rated the movies on multiple dimensions, namely valence and arousal, intensity and discreteness of the induction of one of the six basic emotions and, finally, intensity of the experience of the emotional states defined by a series of emotional adjectives. Erotic clips were effective in the elicitation of a positive emotional state, characterized by high levels of arousal and excitement. On the other hand, Fear clips (selected without blood to avoid disgust reaction) prompted an affect characterized by high arousal, low valence and high levels of reported fear and anxiety. Women reported greater unpleasantness, distress, anxiety and jittery than men to the three negative categories. Compassion clips, characterized by the depiction of crying characters, were able to induce an affective state dominated by sadness and feeling touched, consistent with an empathic reaction to emotional sufferance. Sadness clips, instead, elicited an affective state characterized by sadness together with distress and angst. We also demonstrated that clips depicting natural environments (i.e. Scenery) prompted in the viewer a surprised, inspired affective state, characterized by high valence and arousal (especially in males), a result which suggests that their past categorization as neutral stimuli was inaccurate and problematic.

Non-visual effects of diurnal exposure to an artificial skylight, including nocturnal melatonin suppression

BACKGROUND

Recently, more consideration is being given to the beneficial effects of lighting on the maintenance and promotion of the health and well-being of office occupants in built environments. A new lighting technology using Rayleigh scattering has made it possible to simulate a blue sky. However, to date, no studies have examined the possible beneficial effects of such artificial skylights. The aims of this study were to examine the non-visual effects of artificial skylights and conventional fluorescent lights in a simulated office environment and to clarify the feature effects of the artificial skylights.

METHODS

Participants were 10 healthy male adults. Non-visual effects were evaluated based on brain arousal levels (α-wave ratio and contingent negative variation [CNV]), autonomic nervous activity (heart rate variability [HRV]), work performance, and subjective responses during daytime exposure to either an artificial skylight or fluorescent lights, as well as nocturnal melatonin secretion.

RESULTS

Subjective evaluations of both room lighting-related "natural" and "attractive" items and the "connected to nature" item were significantly higher with the skylight than with the fluorescent lights. Cortical arousal levels obtained from the early component of the CNV amplitude were significantly lower with the skylight than with the fluorescent lights, whereas α-wave ratio and work performance were similar between the two light sources. The HRV evaluation showed that sympathetic nerve tone was lower and parasympathetic nerve tone was higher, both significantly, for the skylight than for the fluorescent lights during daytime. Nocturnal melatonin secretion was significantly greater before and during light exposure at night under the daytime skylight than under the fluorescent lights.

CONCLUSIONS

Our results suggest that artificial skylights have some advantages over conventional fluorescent lights in maintaining ordinary work performance during daytime with less psychological and physiological stress. The findings also suggest that the artificial skylights would enable built environments to maintain long-term comfort and productivity.

Patient-Centered Values and Experiences with Emergency Department and Mental Health Crisis Care

Little is known about what patients value in psychiatric crisis services or how they compare community-based services with those received in the emergency department. Three focus groups (n = 27) were held of participants who had received psychiatric crisis services in emergency departments or a community mental health center. Participants described care experiences and preferences. Focus groups were audio recorded, transcribed, and coded using a value-based lens. Themes included appreciation for feeling respected, basic comforts, and shared decision-making as foundations of quality care. Participants preferred the community mental health center. Research should address long-term outcomes to motivate change in psychiatric crisis care.

Recovery in sensory-enriched break environments: integrating vision, sound and scent into simulated indoor and outdoor environments

To deal with stress and exhaustion at work, personal resources need to be replenished during breaks. The aim of this laboratory study (n = 122 students) was to test the restorative potential of sensory-enriched break environments (SEBEs) in between-subjects with repeated measures design, focusing on the type of the environment (natural outdoor vs. built indoor environment) and sensory input (no sensory input vs. audiovisual input vs. audiovisual and olfactory input). Analyses showed that SEBEs simulating either a natural or a lounge environment were perceived as more pleasant and restorative (fascination/being away) than a standard break room, which in turn facilitated the recovery of personal resources (mood, fatigue, arousal). Moreover, adding a congruent scent to an audiovisual simulation indirectly facilitated the recovery of personal resources via greater scent pleasantness and higher fascination and being away. The current study shows the opportunities for sensory enrichment to foster restoration in break environments.

Daylighting Performance of Solar Control Films for Hospital Buildings in a Mediterranean Climate

One of the main retrofitting strategies in warm climates is the reduction of the effects of solar radiation. Cooling loads, and in turn, cooling consumption, can be reduced through the implementation of reflective materials such as solar control films. However, these devices may also negatively affect daylight illuminance conditions and the electric consumption of artificial lighting systems. In a hospital building, it is crucial to meet daylighting requirements as well as indoor illuminance levels and visibility from the inside, as these have a significant impact on health outcomes. The aim of this paper is to evaluate the influence on natural illuminance conditions of a solar control film installed on the windows of a public hospital building in a Mediterranean climate. To this end, a hospital room, with and without solar film, was monitored for a whole year. A descriptive statistical analysis was conducted on the use of artificial lighting, illuminance levels and rolling shutter aperture levels, as well as an analysis of natural illuminance and electric consumption of the artificial lighting system. The addition of a solar control film to the external surface of the window, in combination with the user-controlled rolling shutter aperture levels, has reduced the electric consumption of the artificial lighting system by 12.2%. Likewise, the solar control film has increased the percentage of annual hours with natural illuminance levels by 100–300 lux.

Psychological Hibernation in Antarctica

Human activity in Antarctica has increased sharply in recent years. In particular during the winter months, people are exposed to long periods of isolation and confinement and an extreme physical environment that poses risks to health, well-being and performance. The present study aimed to gain a better understanding of processes contributing to psychological resilience in this context. Specifically, the study examined how the use of coping strategies changed over time, and the extent to which changes coincided with alterations in mood and sleep. Two crews (N = 27) spending approximately 10 months at the Concordia station completed the Utrecht Coping List, the Positive and Negative Affect Schedule (PANAS), and a structured sleep diary at regular intervals (x 9). The results showed that several variables reached a minimum value during the midwinter period, which corresponded to the third quarter of the expedition. The effect was particularly noticeable for coping strategies (i.e., active problem solving, palliative reactions, avoidance, and comforting cognitions). The pattern of results could indicate that participants during Antarctic over-wintering enter a state of psychological hibernation as a stress coping mechanism.

Advancing Environmental Epidemiology to Assess the Beneficial Influence of the Natural Environment on Human Health and Well-Being

Environmental health research can be oriented across a continuum of effects ranging from adverse to cobenefits to salutogenic. We argue that the salutogenic end of the continuum is insufficiently represented in research and as a basis for environmental protection, even though there is growing evidence that the natural environment plays a critical role in blunting adverse effects and promoting human health and well-being. Thus, we advocate for advancing environmental health research through environmental epidemiology that more fully and directly accounts for the salutogenic effects of the natural environment on individual well-being by (1) defining "natural environments" broadly, from pristine natural areas to urban green infrastructure; (2) considering exposure comprehensively to encompass residential, occupational, and recreational settings, local and distant, day-to-day and occasional; (3) doing individual-level assessments that include both health and well-being outcomes and one's experience of nature, including potential mediation by connectedness to nature and individual perceptions and preferences, as well as sociocultural and demographic effect modifiers; and (4) collecting longitudinal and nationally representative data.

Daylighting and Energy Performance Evaluation of an Egg-Crate Device for Hospital Building Retrofitting in a Mediterranean Climate

Hospital buildings present a significant savings potential in order to meet the objectives of H2020. The improvement of healthcare built environments contributes to improving the health of patients. In this respect, passive measurements must be prioritized, especially in relation to the weakest element of the building thermal enclosure: the window opening. Shading devices allow solar radiation and indoor temperature to be controlled, as well as improving visual comfort, mostly in buildings with a Mediterranean climate. This factor is of great importance when considering the increase in outdoor temperatures expected due to climate change. Unlike other studies in which predictive models are implemented, this paper examines a methodology based on the simultaneous monitoring of ambient variables, in real use and operative conditions, for two hospital rooms located in southern Spain. The aim of this research is to provide a comparative assessment of ambient conditions in a standard room with an egg-crate device and in a non-shaded one. The use of an egg-crate device allows a better yearly performance, improving natural illuminance levels, reducing incident solar radiation on the window, and decreasing artificial lighting consumption. However, its efficiency is greatly conditioned by the user patterns in relation to ambient systems, as the blind aperture level and the activation of the lighting system are directly controlled by users.

Co-designing Urban Living Solutions to Improve Older People's Mobility and Well-Being

Mobility is a key aspect of active ageing enabling participation and autonomy into later life. Remaining active brings multiple physical but also social benefits leading to higher levels of well-being. With globally increasing levels of urbanisation alongside demographic shifts meaning in many parts of the world this urban population will be older people, the challenge is how cities should evolve to enable so-called active ageing. This paper reports on a co-design study with 117 participants investigating the interaction of existing urban spaces and infrastructure on mobility and well-being for older residents (aged 55 + years) in three cities. A mixed method approach was trialled to identify locations beneficial to subjective well-being and participant-led solutions to urban mobility challenges. Spatial analysis was used to identify key underlying factors in locations and infrastructure that promoted or compromised mobility and well-being for participants. Co-designed solutions were assessed for acceptability or co-benefits amongst a wider cross-section of urban residents (n = 233) using online and face-to-face surveys in each conurbation. Our analysis identified three critical intersecting and interacting thematic problems for urban mobility amongst older people: The quality of physical infrastructure; issues around the delivery, governance and quality of urban systems and services; and the attitudes and behaviors of individuals that older people encounter. This identified complexity reinforces the need for policy responses that may not necessarily involve design or retrofit measures, but instead might challenge perceptions and behaviors of use and access to urban space. Our co-design results further highlight that solutions need to move beyond the generic and placeless, instead embedding specific locally relevant solutions in inherently geographical spaces, populations and processes to ensure they relate to the intricacies of place.

Territories of Engagement in the Design of Ecohumanist Healthcare Environments

Background:

Increasingly, architectural and allied designers, engineers, and healthcare facility administrators are being challenged to demonstrate success in adroitly identifying and contextualizing ever-shifting and expanding spheres of knowledge with respect to the role of energy conservation and carbon neutrality in healthcare treatment environments and their immediate exterior environs.

Aim:

This calls for making sense of an unprecedented volume of information on building energy usage and interdigitizing complex and at times contradictory goals with the daily requirements of building occupants. Ecohumanist Design Strategies: In response, a multidimensional framework is put forth with the aim of advancing theory and practice in the realm of designers’, direct caregivers’, and administrators’ engagement with ecohumanist design strategies in the creation of ecohumanist healthcare environments.

Conclusions:

Ten territories for engagement are presented that both individually and collectively express salient themes and streams of inquiry in theory and practice, within an operative framework placing the patient, the patient’s significant others, and the caregiver at the center of the relationship between the built environment and occupant well-being.

Why We Need More Nature at Work: Effects of Natural Elements and Sunlight on Employee Mental Health and Work Attitudes

This study investigated the effects of natural elements and direct and indirect sunlight exposure on employee mental health and work attitudes. We recruited participants via an online panel from the United States and India, and analyzed data from 444 employees. Natural elements and sunlight exposure related positively to job satisfaction and organizational commitment, and negatively to depressed mood and anxiety. Direct sunlight was a dominant predictor of anxiety; indirect sunlight was a dominant predictor of depressed mood, job satisfaction, and organizational commitment. Natural elements buffered the relationship between role stressors and job satisfaction, depressed mood, and anxiety. We also found that depressed mood partially mediated the relationship between natural elements and job satisfaction. We discuss scientific and policy implications of these findings.

Restoration in Its Natural Context: How Ecological Momentary Assessment Can Advance Restoration Research

More and more people use self-tracking technologies to track their psychological states, physiology, and behaviors to gain a better understanding of themselves or to achieve a certain goal. Ecological Momentary Assessment (EMA) also offers an excellent opportunity for restorative environments research, which examines how our physical environment (especially nature) can positively influence health and wellbeing. It enables investigating restorative health effects in everyday life, providing not only high ecological validity but also opportunities to study in more detail the dynamic processes playing out over time on recovery, thereby bridging the gap between laboratory (i.e., short-term effects) and epidemiological (long-term effects) research. We have identified four main areas in which self-tracking could help advance restoration research: (1) capturing a rich set of environment types and restorative characteristics; (2) distinguishing intra-individual from inter-individual effects; (3) bridging the gap between laboratory and epidemiological research; and (4) advancing theoretical insights by measuring a more broad range of effects in everyday life. This paper briefly introduces restorative environments research, then reviews the state of the art of self-tracking technologies and methodologies, discusses how these can be implemented to advance restoration research, and presents some examples of pioneering work in this area.

The relationship between perceived health and physical activity indoors, outdoors in built environments, and outdoors in nature

Background:

A body of evidence shows that both physical activity and exposure to nature are connected to improved general and mental health. Experimental studies have consistently found short term positive effects of physical activity in nature compared with built environments. This study explores whether these benefits are also evident in everyday life, perceived over repeated contact with nature. The topic is important from the perspectives of city planning, individual well-being, and public health.

Methods:

National survey data (n = 2,070) from Finland was analysed using structural regression analyses. Perceived general health, emotional well-being, and sleep quality were regressed on the weekly frequency of physical activity indoors, outdoors in built environments, and in nature. Socioeconomic factors and other plausible confounders were controlled for.

Results:

Emotional well-being showed the most consistent positive connection to physical activity in nature, whereas general health was positively associated with physical activity in both built and natural outdoor settings. Better sleep quality was weakly connected to frequent physical activity in nature, but the connection was outweighed by other factors.

Conclusion:

The results indicate that nature provides an added value to the known benefits of physical activity. Repeated exercise in nature is, in particular, connected to better emotional well-being.
