Recent research has confirmed our suspicion that green is good, especially in urbanised areas.
According to the study by the University of Exeter, UK, living in an urban area with relatively high levels of green space can have a significantly positive impact on well-being (about equal to a third of the impact of being married), along with improving mood and cognitive functioning.
By examining data from a national survey that followed UK households over time, researchers found that individuals reported less mental distress and higher life satisfaction when they were living in greener areas.
