A study led by the Barcelona Institute for Global Health shows for the first time that exposure(接触)to green space during childhood may have beneficial(有益的)effects on brain development.

The study was performed among 253 schoolchildren from the BREATHE project in Barcelona (Spain). Lifelong exposure to green space in the living places was recorded—using the satellite—based information on the children's addresses from birth up through to the time of the study. Brain structure was studied using 3D MRI(核磁共振图像). Working memory and inattentiveness were graded with computers.

The primary schoolchildren who have been raised in homes surrounded by more greenspace tend to present with larger volumes of white and grey matter in certain areas of the brain. These differences are connected with beneficial effects on cognitive function(认知功能). Moreover, larger volumes of white and grey matter might lead to better working memory and less inattentiveness.

"This is the first study that shows the connection between long—term exposure to green space and brain structure." Says, the leading researcher of the study, "Our findings suggest that exposure to green space early in life could result in beneficial structural changes in the brain. It also shows the lasting effects of early life exposure to greenness on our health."

This study also suggests that it is beneficial to increase greenness in cities. Green space can provide children with chances for psychological restoration(心理康复)and prompt important exercises in discovery, creativity and risk taking. These exercises in turn positively(肯定地)influence different aspects of brain development. What's more, greener areas often have lower levels of air pollution, which could bring indirect benefits for brain development.

Anyway, further studies are needed to prove the findings in other populations, settings and climates. And researchers need to examine differences according to the nature and quality of green space.
