Spending time in natural environments can benefit health and well-being, but exposure-response relationships are under-researched. We examined associations between recreational nature contact the last seven days self-reported well-being. Participants (n = 19,806) were drawn from Monitor of Engagement with Natural Environment Survey (2014/15-2015/16); weighted to be nationally representative. Weekly was categorised using 60 min blocks. Analyses controlled for residential greenspace other...

Abstract Living near, recreating in, and feeling psychologically connected to, the natural world are all associated with better mental health, but many exposure-related questions remain. Using data from an 18-country survey ( n = 16,307) we explored associations between multiple measures of health (positive well-being, distress, depression/anxiety medication use) and: (a) exposures (residential/recreational visits) to different settings (green/inland-blue/coastal-blue spaces); (b) nature...

Introduction Proximity and access to water have long been central human culture accordingly deliver countless societal benefits. Over 200 million people live on Europe's coastline, aquatic environments are the top recreational destination in region. In terms of public health, interactions with ‘blue space’ (eg, coasts, rivers, lakes) often considered solely risk drowning, microbial pollution). Exposure blue space can, however, promote health well-being prevent disease, although underlying...

This paper summarizes the epidemiological evidence for adverse health effects associated with disinfection by-products (DBPs) in drinking water and describes potential mechanism of action. There appears to be good a relationship between exposure DBPs, as measured by trihalomethanes (THMs), bladder cancer, but other cancers including colorectal cancer is inconclusive inconsistent. some an association specifically THMs, little gestational age/intrauterine growth retardation and, lesser extent,...

The available evidence of the effects air pollution and noise on behavioral development is limited, it overlooks exposure at schools, where children spend a considerable amount time.We aimed to investigate associations traffic-related pollutants (TRAPs) school schoolchildren.We evaluated 7-11 years age in Barcelona (Catalonia, Spain) during 2012-2013 within BREATHE project. Indoor outdoor concentrations elemental carbon (EC), black (BC), nitrogen dioxide (NO2) were measured schools two...

We aimed estimate cases of that might be attributable ELF MF European Union (EU27), if associations seen studies were causal. estimated distributions using identified existing literature.

Abstract The effects of ‘nature’ on mental health and subjective well-being have yet to be consistently integrated into ecosystem service models frameworks. To address this gap, we used data from an 18-country survey test a conceptual model integrating with services, initially proposed by Bratman et al. We analysed range individual contextual factors in the context 14,998 recreational visits blue spaces, outdoor environments which prominently feature water. Consistent model, outcomes were...

The role of neighbourhood nature in promoting good health is increasingly recognised policy and practice, but consistent evidence for the underlying mechanisms lacking. Heterogeneity exposure methods, outcome measures, population characteristics, little exploration recreational use or different types green blue space, multiple separate mediation models previous studies have limited our ability to synthesise findings draw clear conclusions. We examined pathways linking with general using a...

Abstract Exposure to natural environments is associated with a lower risk of common mental health disorders (CMDs), such as depression and anxiety, but we know little about nature-related motivations, practices experiences those already experiencing CMDs. We used data from an 18-country survey explore these issues (n = 18,838), taking self-reported doctor-prescribed medication for and/or anxiety indicator CMD ( n 2698, 14%). Intrinsic motivation visiting nature was high all, though slightly...

It is well established that outdoor natural environments - or green spaces have the potential to serve as therapeutic landscapes and are a public health resource. Less known about extent which "water-related (blue spaces) may benefit health. As with space, benefits resulting from blue space use probably depend on place quality. However, lack of comparable environmental quality data hampers planning design their inclusion in health-related policies. This paper presents novel tool BlueHealth...

Varied categorisations of residential distance to bluespace in population health studies make comparisons difficult. Using survey data from eighteen countries, we modelled relationships between blue spaces (coasts, lakes, and rivers), self-reported recreational visits these environments at least weekly, with penalised regression splines. We observed exponential declines visit probability increasing all three demonstrated the utility derived categorisations. These categories may be broadly...
