Growing up in a green area may help support mental health

New research from Aarhus University in Denmark suggests that people who have grown up in close contact with nature are much less likely to develop mental health problems in adulthood than peers who had less access to green space as children.

According to recent studies, mental health problems have been on the rise in the United States, with particular increases in cases of anxiety and depression.

The reasons behind this worrying trend are as numerous as they are complex, ranging from the evermore stressful demands of modern-day life, such as being constantly "on call" through email, phone, and social media, to environmental factors, such as pollution.

Researchers from around the world have been trying to disentangle each of these risk factors, so as to get a better idea of what changes are necessary to prevent mental health problems from developing into an increasingly serious, society-wide issue.

Now, a new study from postdoctoral researcher Kristine Engemann and colleagues from Aarhus University in Denmark has found a link between growing up in a natural environment and enjoying better mental health in adulthood.

Green spaces may safeguard our minds

In their research — the findings of which appear in PNAS — they used satellite data from 1985 to 2013 to identify the green spaces in close proximity to the childhood homes of more than 900,000 Danes.

They then correlated these data with this population's risk of developing one out of 16 different mental health conditions throughout adulthood.

The researchers found that people who grow up surrounded by green areas have an up to 55 percent lower risk of developing mental health problems as adults than others.

These results remained in place even after the team adjusted for potentially modifying factors, including a person's socioeconomic status, their family history of mental health problems, and migration from rural to urban areas.

"Our data is unique," notes Engemann. "We have had the opportunity to use a massive amount of data from Danish registers of, among other things, residential location and disease diagnoses and compare it with satellite images, revealing the extent of green space surrounding each individual when growing up," she explains.

The Danish study also reveals that the longer someone spent surrounded by nature during their childhood — from early infancy until the age of 10 years old — the more likely they are to experience good mental health later in life.

"With our dataset, we show that the risk of developing a mental disorder decreases incrementally the longer you have been surrounded by green space from birth and up to the age of 10. Green space throughout childhood is therefore extremely important."
