Study Finds That Playing in Nature Boosts Children’s Immune Systems - article from My Modern Met
Playing outside is an important and healthy part of childhood. Away from screens, children need time to breathe fresh air and get dirty as they explore the world around them. Many parents and teachers believe that getting a bit messy in nature is beneficial to children's immune systems. A recent study by the University of Helsinki has proved this parental folk wisdom to be true. Focused on pre-school aged children, the study found that playing on a forest floor drastically boosted children’s immune systems and microbiomes—both critical for overall health.
Published in the journal Science Advances, the study focused on daycare centers serving children ages three to five in the Finnish cities of Lahti and Tampere. Three of the daycare centers had playgrounds with natural, forest earth. Three had gravel yards, which they maintained as a control throughout the study. The experimental cohorts of children attended another four centers which had previously had gravel playgrounds but were converted to forest earth for research. Scientists collected biological samples from each child before the study, then again after 28 days of sustained play in their respective environments.
