The aetiology of mood disorders is complex as it is determined by genetic, social, and environmental factors. In recent years, evidence on the interplay between mental health and the environment has grown significantly. Cross-sectional and longitudinal studies have observed associations between surrounding greenness or green space and lower stress, psychological distress, and depressive symptoms. Furthermore, experimental fieldwork, inspired by the well-established Japanese “forest bathing” practices, is starting to produce clear evidence of the benefits of nature experience for health promotion, including mental health. This is at odds with the fact that overall, 54% of the world's population now lives in urban settings, which includes quantitatively and qualitatively diminished contact with natural environments, thus posing a serious threat to mental health. As environmental factors are often modifiable, they can be important targets for public health policies. However, before we turn to nature-based therapies we need to develop a conceptual framework and prioritize research directions to recognize the pathways and mechanisms activated by natural environments, thus delivering actionable targets for intervention.
In this Educational update session, we will present recent compelling data on the negative effects of urbanicity and city living on brain function. Additionally, we will highlight how environmental exposures, such as those afforded by urban green spaces, can influence various aspects of human health as well as how we can create healthier cities by exploiting environment-based solutions.
This session was recorded on 8 October 2023 at the 36th ECNP Congress in Barcelona.
