Daycares in Finland Built a 'Forest Floor', And It Changed Children's Immune Systems
Makes sense to me. I've always believed in the hygiene hypothesis: Kids' immune systems need a workout when they're growing up or else they'll develop auto-immune disorders as their immune systems turn against their own bodies for lack of anything else to attack.
When daycare workers in Finland rolled out a lawn, planted forest undergrowth such as dwarf heather and blueberries, and allowed children to care for crops in planter boxes, the diversity of microbes in the guts and on the skin of young kids appeared healthier in a very short space of time.
Compared to other city kids who play in standard urban daycares with yards of pavement, tile and gravel, 3-, 4-, and 5-year-olds at these greened-up daycare centres in Finland showed increased T-cells and other important immune markers in their blood within 28 days.
"We also found that the intestinal microbiota of children who received greenery was similar to the intestinal microbiota of children visiting the forest every day," says environmental scientist Marja Roslund from the University of Helsinki.
