Schoolchildren who have been raised in homes surrounded by nature and greenspace tend to have larger volumes of white and gray matter in areas of the brain associated with memory and attention, research at the Barcelona Institute for Global Health (ISGlobal) finds.
The study was performed in a subcohort of 253 schoolchildren from the BREATHE project in Barcelona (Spain). Lifelong exposure to residential greenspace was estimated using satellite-based information on the children's addresses from birth up through to the time of the study. Brain anatomy was studied using high-resolution 3D magnetic resonance images (MRI). Working memory and inattentiveness were evaluated with computerized tests.

An active brain can certainly help in improving memory by strengthening the connections between neural impulses in brain.

"This is the first study that evaluates the association between long-term exposure to greenspace and brain structure," says Dr. Payam Dadvand, ISGlobal researcher and leading author of the study. "Our findings suggest that exposure to greenspace early in life could result in beneficial structural changes in the brain."
The data analysis showed that long-term exposure to greenness was positively associated with white and gray matter volume in some parts of the brain that partly overlapped with those associated with higher scores on cognitive tests. Moreover, peak volumes of white and gray matter in the regions associated with greenspace exposure predicted better working memory and reduced inattentiveness.

Contact to nature has been thought to be essential for brain development in children. A previous study of 2,593 children ages 7 to 10 from the BREATHE project showed that, during the 12-month course of the study, children who attended schools with higher outdoor greenspace had a greater increase in working memory and a greater reduction in inattentiveness than children who attended schools with less surrounding greenness.
The Biophilia hypothesis suggests an evolutionary bond of humans to nature. Accordingly, green spaces are suggested to provide children with opportunities for psychological restoration and prompt important exercises in discovery, creativity and risk-taking, which, in turn, are suggested to positively influence different aspects of brain development. Furthermore, greener areas often have lower levels of air pollution and noise and may enrich microbial inputs from the environment, all of which could translate into indirect benefits for brain development.
"The study adds to growing evidence suggesting that early life exposure to green space and other environmental factors can exert measurable and lasting effects on our health through the life course," says co-author Michael Jerrett, department chair and professor of Environmental Health Sciences at the UCLA Fielding School of Public Health.
"These results also might provide clues on how such structural changes could underlie the observed beneficial effects of greenspace exposure on cognitive and behavioral development," explains Dr. Jesus Pujol, from the Radiology unit at Hospital del Mar and co-author of the study.
"This study adds to the existing evidence about the benefits of transforming our cities by increasing access to the natural environment," says Prof. Jordi Sunyer, an ISGlobal researcher and last author of the study.
Further studies are needed to confirm the results in other populations, settings and climates, evaluate other cognitive and neurological outcomes and examine differences according to the nature and quality of greenspace and children's access to and use of them.
