Playing through the greenery and litter of a mini forest's undergrowth for just one month may be enough to change a child's immune system, according to an experiment in Finland.
When daycare workers 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 the 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 centers 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," explained environmental scientist Marja Roslund from the University of Helsinki in 2020, when the research was published.

Prior research has shown early exposure to green space is somehow linked to a well-functioning immune system, but it's still not entirely clear whether that relationship is causal or not.

In the winter sledding in it, and some of those sled runs included shortcuts through cow pies !
My immune system has held out for a long time now.

(found it. it is in the health forum. Titled "doctors couldn't help".)
To all of it I want to say NSS. Just now figuring this out?

(36,201 posts)Get the kids outside to play and skin their knees. Play in the sand or dirt with others. If in a very urban environment, buy some dirt and set up flowerpots in the window--and be sure that the kids play in the dirt. Let them go to the park and be dirty, assuming it's not a paved-over park. Eat without washing their hands. Avoid hand sanitizer. Don't coddle them--learn to resolve small problems so they have the skills to scale them up to larger problems.
Kids are anti-fragile. Unless something does serious damage, it's likely to spur resilience.

It seems to provide some kind of cardiovascular benefits beyond just vitamin D.

"Exposing skin to sunlight may help to reduce blood pressure, cut the risk of heart attack and stroke - and even prolong life, a study suggests. Researchers have shown that when our skin is exposed to the sun's rays, a compound is released in our blood vessels that helps lower blood pressure"
