Quantifying physiological health efficiency and benefit threshold of greenspace exposure in typical urban landscapes. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024:124726. [PMID: 39173868 DOI: 10.1016/j.envpol.2024.124726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 08/11/2024] [Accepted: 08/12/2024] [Indexed: 08/24/2024]
Abstract
Although greenspace exposure has physiological health benefits, there is insufficient research on the threshold effect of health benefits in typical urban landscapes. Here we selected five typical urban landscapes (open greenspace, semi-closed greenspace, closed greenspace, bluespace, grey space) in 15 urban parks in Xiamen, China, and applied the physiological health threshold model to calculate the efficiency threshold and benefit threshold of greenspace exposure by continuously monitoring the changes of two physiological indicators-electroencephalography (EEG) and heart rate (HR). (1) The EEG threshold results show that compared with greenspace exposure, bluespace exposure can reach the physiological health efficiency threshold faster (4-5 min) but does not show an advantage in terms of benefit threshold. The more open the greenspace, the faster it can reach the efficiency threshold (5-6 min), but the higher the canopy density of the (closed) greenspace, the shorter the time to reach the efficiency threshold (8-9 min). (2) The HR threshold shows that bluespace and open greenspace are the fastest to reach the efficiency threshold (1 min), with the remaining greenspace reaching it after 6-7 min. The benefit threshold was reached faster in the bluespace (11 min) than in the greenspace (18-21 min), and the degree of openness of the greenspace has no significant effect on the speed of benefit thresholds. (3) Combining the results of EEG and HR thresholds, it can be seen that bluespace is better at reducing stress, while open greenspace can reach efficiency thresholds more quickly. This study confirms the physiological health threshold model, offering a reference for urban greenspace planning to enhance residents' stress management and health.

Li J, Trivic Z. Impact of "blue-green diet" on human health and wellbeing: A systematic review of potential determinants in shaping the effectiveness of blue-green infrastructure (BGI) in urban settings. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 926:171397. [PMID: 38438033 DOI: 10.1016/j.scitotenv.2024.171397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 02/12/2024] [Accepted: 02/28/2024] [Indexed: 03/06/2024]
Abstract
Discourses concerning the potential health benefits of blue-green infrastructure (BGI) have gained momentum, highlighting its positive influence on human health and wellbeing. While studies have explored the concept of "Nature Pyramid" and the role of exposure to natural environments in promoting health, the role of water elements remains underexplored. Rooted in this concept, this study proposed a notion of "blue-green diet" as a framework to understand the intricate mechanisms and determinants of optimal blue-green exposure. Understanding the relationship between these determinants and their health-related impacts can facilitate the enhancement of BGI design, leading to greater effectiveness in promoting health and wellbeing and supporting sustainable urban development strategies. To enhance the comprehension of the "blue-green diet", this study conducted a systematic literature review to grasp the underlying mechanisms behind its beneficial effects, focusing on two key determinants of "blue-green diet", which are also derived from the concept of the "Nature Pyramid": (1) the type of BGI and (2) the mode of interaction with and within BGIs. Under the search of BGI's overall health impacts, this study selected 54 journal publications concerning BGI's type and interaction mode from Web of Science and Scopus since 2010. The review revealed significant disparities in the health benefits provided by different types of BGI (in terms of artificial extent and scale) and between active and passive interaction modes. It examines how to balance natural and artificial elements for enhancing the benefits of BGI and discusses the attributes of BGI that encourage diverse and meaningful interaction patterns. These efforts collectively aim to optimize BGI design and planning, increase its capacity to promote health, and extend its benefits to a wider range of individuals. Future research should encompass a broader spectrum of determinants, such as diverse BGI settings, visit frequency and duration, and user's social-cultural backgrounds.

Abstract
BACKGROUND Increasingly, public health faces challenges requiring complex, multifaceted and multi-sectoral responses. This calls for systems-based approaches that facilitate the kind of collective and collaborative thinking and working required to address complexity. While the literature on systems thinking, system dynamics and the associated methodologies is extensive, there remains little clear guidance on how to plan, govern and implement participatory systems approaches within a co-creation process. METHODS We used a three-step process to develop DISCOVER, a framework for implementing, and governing systems-based co-creation: Stage 1: We conducted a literature analysis of key texts to identify well-documented methods and phases for co-creation using a systems approach, as well as areas where gaps existed. Stage 2: We looked for the most appropriate methods and approaches to fill the gaps in the knowledge production chain. Stage 3: We developed the framework, identifying how the different tools and approaches fit together end-to-end, from sampling and recruiting participants all the way through to responding with an action plan. RESULTS We devised DISCOVER to help guide researchers and stakeholders to collectively respond to complex social, health and wider problems. DISCOVER is a strategic research planning and governance framework that provides an actionable, systematic way to conceptualise complex problems and move from evidence to action, using systems approaches and co-creation. In this article, we introduce the eight-step framework and provide an illustrative case study showcasing its potential. The framework integrates complementary approaches and methods from social network analysis, systems thinking and co-creation literature. The eight steps are followed sequentially but can overlap. CONCLUSIONS DISCOVER increases rigour and transparency in system approaches to tackling complex issues going from planning to action. It is being piloted in environmental health research but may be suitable to address other complex challenges and could be incorporated into research proposals and protocols for future projects.

Blue prescription: A pilot study of health benefits for oncological patients of a short program of activities involving the sea. Heliyon 2023; 9:e17713. [PMID: 37483694 PMCID: PMC10362171 DOI: 10.1016/j.heliyon.2023.e17713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 06/12/2023] [Accepted: 06/26/2023] [Indexed: 07/25/2023] Open
Abstract
Performing outdoor activities in blue spaces can help improve human health and mental well-being by reducing stress and promoting social relationships. The number of people surviving cancer has increased globally to experience this disease as a life-changing and chronic condition with physical and psychosocial symptoms that have negative impacts on their quality of life. While there has been a growth of programs in green spaces to meet the needs of cancer patients, such as follow-up post-treatment care, support groups and physical activity programs, very few studies have examined the effects of activities involving the sea for the health and well-being of oncology patients. This is the first study to evaluate whether different outdoor activities in blue spaces can benefit oncological patients' physical and mental health using smartwatches, sphygmomanometers and Profile of Mood States (POMS) questionnaires. We assessed changes in blood pressure, heart rate, sleep quality and mental health of 16 patients after twelve sessions of three different activities (walking, beach and snorkelling) and four sessions of a control activity. While no significant differences between activities were observed in terms of the data gathered by the smartwatches, a gradient of positive results for human mental health was observed towards exposure to a blue space, assessed through POMS questionnaires. Results show that exposure to blue spaces contributes to tension and anger reduction and improves the vigour mood state of oncology patients. No significant increases in patients' heart rate were recorded after the beach and snorkelling activities, with results similar to the control activity, suggesting that the contribution may be to participants' relaxation.
