“…79 That some of the beneficial effects of greenness are due to reduction in air pollutants is suggested by the observations that the effects of PM 10 on cardiovascular mortality are attenuated in greener areas 57 and that greenspaces diminish the health impact of PM on hospitalization, 60 respiratory mortality, 56 as well as increased risk of diabetes and prediabetes, 80 glucose homeostasis, 81 hypertension, 82 and mortality. 83 We have found that in areas of low greenness, both PM 2.5 and ozone were positively associated with pulse pressure. Ozone was positively associated with augmentation and systolic blood pressure.…”

Accumulating evidence suggests that living in areas of high surrounding greenness or even brief exposures to areas of high greenery is conducive to cardiovascular health, which may be related to the environmental, social, psychological, and physiological benefits of greenspaces. Recent data from multiple cross-sectional, longitudinal, and cohort studies suggest that living in areas of high surrounding greenness is associated with a lower risk of all-cause and cardiovascular mortality. High levels of neighborhood greenery have been linked also to a decrease in the burden of cardiovascular disease risk factors as reflected by lower rates of hypertension, dyslipidemia, and diabetes. Those who live in greener environments report better mental health and more frequent social interactions, which can benefit cardiovascular health as well. In this narrative review, we discuss evidence linking greenspaces to cardiovascular health as well as the potential mechanisms underlying the beneficial effects of greenspaces, including the impact of vegetation on air, noise and light pollution, ambient temperature, physical activity, mental health, and biodiversity. We review literature on the beneficial effects of acute and chronic exposure to nature on cardiovascular disease risk factors, inflammation and immune function, and we highlight the potential cardiovascular effects of biogenic volatile organic compounds that are emitted by trees and shrubs. We identify current knowledge gaps in this area and underscore the need for additional population studies to understand more clearly and precisely the link between greenness and health. Such understanding is urgently needed to fully redeem the promise of greenspaces in preventing adverse environmental exposures, mitigating the effects of climate change, and creating healthier living environments.

“…The importance of greenspace in mitigating air pollution and its associated impact on human health has been shown in several recent studies, with some authors highlighting its impact on improved cognitive performance, 81 improved lung function, 42 lower chronic health conditions including hypertension and diabetes, 82 decreased hospitalizations from cardiovascular diseases, 83 and decreases in mortality. 84 In order to better understand interactions between urban greenspace and air pollution, we investigated associations between urban greenspace levels (determined using both GSVand satellite imagery-derived metrics) and Google Air Viewderived air quality measurements resolved in extremely high spatial resolution along the entire road network of a major city. A spatial lag regression model was employed to understand the relationship between urban greenspace and pollution metrics on varying spatial scales.…”

Unprecedented levels of urbanization have escalated urban environmental health issues, including increased air pollution in cities globally. Strategies for mitigating air pollution, including green urban planning, are essential for sustainable and healthy cities. State-of-the-art research investigating urban greenspace and pollution metrics has accelerated through the use of vast digital data sets and new analytical tools. In this study, we examined associations between Google Street View-derived urban greenspace levels and Google Air View-derived air quality, where both have been resolved in extremely high resolution, accuracy, and scale along the entire road network of Dublin City. Particulate matter of size fraction less than 2.5 μm (PM2.5), nitrogen dioxide, nitric oxide, carbon monoxide, and carbon dioxide were quantified using 5,030,143 Google Air View measurements, and greenspace was quantified using 403,409 Google Street View images. Significant (p < 0.001) negative associations between urban greenspace and pollution were observed. For example, an interquartile range increase in the Green View Index was associated with a 7.4% [95% confidence interval: −13.1%, −1.3%] decrease in NO2 at the point location spatial resolution. We provide insights into how large-scale digital data can be harnessed to elucidate urban environmental interactions that will have important planning and policy implications for sustainable future cities.

“…Definitions of greenness in the remaining 13 research articles were tree canopy cover [ 33 , 34 ], percentage of green space [ 35 – 39 ], or landcover/land-use maps [ 40 – 45 ]. Tree canopy cover refers to areas shaded by trees, more specifically branches and leaves and other vegetation foliage exceeding 5 feet (1.52 m) in height.…”

“…Respiratory mortality, including lung cancer mortality, was the most investigated outcome in relation to greenness within the field of respiratory outcomes. As many as 25 original research papers included in this review focused on respiratory mortality [ 6 – 19 , 35 , 36 , 43 , 45 , 46 ] or lung cancer mortality [ 4 – 6 , 8 , 12 , 14 , 35 , 40 – 45 ]. Most of the mortality studies investigated greenness in the form of NDVI, with interquartile range (IQR) as the preferred unit of increase in the analyses.…”

Many studies have shown that greenness has beneficial health effects, particularly on psychological and cardiovascular outcomes. In this narrative review, we provide a synthesis of knowledge regarding greenness exposure and respiratory health. The following outcomes were reviewed: respiratory mortality, lung cancer mortality, lung cancer incidence, respiratory hospitalisations, lung function, COPD, and asthma. We identified 174 articles through a literature search in PubMed, of which 42 were eligible for inclusion in this review. The most common marker for greenness exposure was the normalised difference vegetation index (NDVI), which was used in 29 out of 42 papers. Other markers used were tree canopy cover, landcover/land-use, plant diversity, density of tall trees and subjectively perceived greenness. We found beneficial effects of greenness in most studies regarding respiratory mortality, lung cancer incidence, respiratory hospitalisations and lung function. For lung cancer mortality, asthma and COPD, the effects of greenness were less clear cut. While many aspects of greenness are beneficial, some aspects may be harmful, and greenness may have different health effects in different population subgroups. Future studies of greenness and respiratory diseases should focus on asthma and COPD, on effects in different population subgroups and on disentangling the health effects of the various greenness dimensions.
