Using data from 5,000 UK households over 17 years, researchers found that living in a greener area had a significant positive effect.

 

The findings could help to inform urban planners and have an impact on society at large, they said.

 

The study is published in the journal Psychological Science.

 

The research team examined data from a national survey that followed more than 5,000 UK households and 10,000 adults between 1991 and 2008 as they moved house around the country.

 

They asked participants to report on their own psychological health during that time to estimate the "green space effect".

 

Dr Mathew White and colleagues at the European Centre for the Environment and Human Health found that individuals reported less mental distress¹ and higher life satisfaction when they were living in greener areas.

 

This was true even after the researchers accounted for changes over time in participants' income, employment, marital² status, physical health and housing type.

 

 

Dr White compared the scale of the effects of living in a greener area to "big-hitting" life events such as marriage.

 

"We've found that living in an urban area with relatively³ high levels of green space can have a significantly positive impact on wellbeing, roughly equal to a third of the impact of being married."

 

The effect was also found to be equivalent to a tenth of the impact of being employed, as opposed to unemployed⁴.

 

Even when stacked up against other factors that contribute to life satisfaction, living in a greener area had a significant effect, the study said.
