Daycares in Finland Built a 'Forest Floor', And It Changed Children's Immune Systems:

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 a small new experiment.

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.

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

The experiment in Finland is the first to explicitly manipulate a child's urban environment and then test for changes in their micriobiome and, in turn, a child's immune system.

While the findings don't hold all the answers, they do support a leading idea - namely that a change in environmental microbes can relatively easily affect a well-established microbiome in children, giving their immune system a helping hand in the process.

    Children don't even get a floor of any kind - they sit in front of a TV and watch Disney all day long.

    Children need to play with their hands and with their peers. They need to get dirty. They need to chew bugs. They need to test their social relationshis, including fighting each other and checking private parts. All of this is stolen from American children and substituted by drugs.

    Zero tolerance is the worst that ever happened to children.

          I was thinking that most kids are too poor to be very well insulated from bacteria.
          but I guess cockroaches and other inner city stuff is not the same as a forest floor.
          when we lived in baltimore though, I saw plenty of crawling kids explore the relatively natural growth around the playground, and most people actually lived in houses with lawns (where kids would play).
          and I'm under the impression baltimore is pretty bad as far as "large inner city population" goes.

            I'd say that there is a pretty drastic difference between inner city scum and forest floor - both are filled with active beasties, and the city scum will take you down in a hurry if you're not immune to it. Case in point: I cut my hand while mountain biking 100km East of Dusseldorf. I didn't have proper first aid, but it wasn't a problem for several days... until I rode into town. 6 hours after arriving in Dusseldorf I was in the ER with blood poisoning spreading rapidly up from my hand through my elbow before it got treated. The city biome tried to kill me, but that's why they have hospitals.

            Get into a forest floor and there's all manner of leaf-rot worm guts bear crap and other stuff you just don't get in the city, but most of humanity probably did evolve with until ~5000 years ago.

              I sincerely doubt that a "city biome" was responsible. You were probably almost immediately infected after injury, if not then it was during the several days you went untreated before reaching the city. There is no way an infection like that comes about within 6 hours, it just happened to escalate from festering to serious after you arrived there.

                      Exactly, the shower in the youth hostel had ... something ... that got in through the scab which was loosened by the water. Whatever it was, it responded to antibiotics almost immediately, and the German ER didn't bankrupt me which was nice.

                        That is a nice feature of other health care systems. But the infection you are describing is the hostel's problem not the "city biome" problem. The hostel and any short-term hospitality facility can get straight up disgusting if not cleaned frequently enough, which they often aren't especially the "wet" areas and sheets. That sort of thing is largely caused by that unique set of circumstances present and not its "city" status per se.

              I'm going with Joe Desertrat on that. Whatever caused your infection was picked up at the time you were injured, or soon after. It's highly unlikely that you wandered around for days, only to be attacked by some random germs after you entered the city. Whichever germs or bacteria caused your infection required a couple days or more to be fruitful and multiply to the point that you became aware of them.

              Yes, because as we all know the moment a single bacterium get's into your cut it immediately presents symptoms. It definitely does not take, say a day or two, to reproduce into a large enough population to cause you harm.

                Shitty tip of the day: if you ever see a red line spreading up from your wrist toward your elbow - just chill out man, that's nothin' to worry about. /s

                The open cut was washed in a youth hostel shower (no soap available) about 3 hours after entering the city, the red line started showing up about an hour later - I suspect it entirely started from something washed in in the shower, but I could have picked something up while working on the bike on the way in. The ER doc called it blood poisioning, but Lymphangitis is a more precise description - I first noticed the tender red stripe when it was less than 1cm long, but within the hour it took to get to the ER it had grown to about 12cm long.

                But, sure, it could have been bacteria picked up several days earlier - I'm sure your perspective on it is much more informed than mine. /s

        You've heard the term "helicopter parents". People who constantly worry about EVERYTHING child related.

        Fact is, you simply don't see hordes of children running around the country side, like we saw as children. You don't see kids wandering the neighborhoods in the suburbs.

        There was a rather memorable story of the police being called to investigate a youngish child who was seen walking to a playground. This isn't the same story I had in mind, but it makes the point: kids DO NOT get out and about anymore.

          On my drive home through the countryside, I will see kids sometimes riding bikes on the road, but if they are off through fields and forests and you can't see what is out there. In my childhood I was rarely near the road but usually out in the field or woods out back. The amount of joy a 2nd grader gets with a pack of firecrackers and field dotted with cowpies is unmeasurable. Anyway, I suspect the country has fewer helicopter parents but I also don't have any hard data to back that up. Just saying that you aren't likely to be able to see the free ranging country kids from the road most of the time.

          Once upon a time in a country near you children would go to schools with rifles. They'd put their rifles into the principal office and take them back after the classes so they could get a rabbit on the way back home. Did I mention they were hiking through the forest?
          My own father even though we was born across an ocean on the other side of the planet did exactly this. He would take his shotgun to the school, leave it with the janitor, and try to get a rabbit on the way back home.He was 13 when his father died and he inherited the shotgun. I still own this shotgun totally illegal and unregistered in that part of the planet. I keep it in top condition and test it regularly. I learned how to use it as the same age - 13 - and I learned it well

      Medical schools are already finding that many incoming students lack the fine motor skills necessary to learn surgery. They need lots of remedial training to get to a minimum acceptable level before they can even start the applied studies. Similar for kindergarten, many incoming kids don't have the rough motor skills to participate in many activities, including drawing with crayons or fat pencils. There are articles around on both situations.

      Stamina and strength are also things of the past. Anecdotally I have heard about kids that can't even travel a block without getting winded. That comes from multiple hours per day curved into a C-shape over a tiny screen, either a smartphone or a tablet. That comes in part from "engagement" over usability and effciency. Smartphone applications are written for addictiveness and "engagement" to occupy attention fully while maximizing the time spent interacting with the program, rather than getting the job done quickly and without though. Despite that, smartphones are given to very small kids as pacifiers and babysitters. That's something I see everywhere. One part which I suspect but have not seen hard documentation for, yet, is that the techniques which the smartphones applications and services use to achieve addictiveness are also cultivating ADHD on top of the lack of motor skills. Even videos are heading that way, a long take in a Tiktok style video is measured in tenths of a second. That's not entertainment, that's just plain fucking with cognitive abilities. Society requires participation, the prerequisites for that are being mined away from the younger and youngest generations in circulation.

      Oh, well. While we won't be the first civilization to have collapsed completely but, having pulled the ladder up after us, we will be the last.

        There are definitely problems with "smartphone parenting" starting, I think, with parents being addicted to their screens before they even give them to their children. A recurrent phenomenon I've experienced when taking my kid to the park or library is that other kids we don't know attach themselves to us because I'm the one parent actually interacting with my child. The edges of the park/kids area will be lined with adults staring at their phones and I'll have one to three of their children wanting me to "watch this" or help with that.

        On the other side of things, I very much agree that "designed for addiction" is an even bigger problem for children than adults but I don't think the cut of the videos is really an issue. There's a very small list of youtube videos I download for my child - they never see the app or webpage. What's really interested me about the video is that our neighbors kid, who watched allot more "kids content" than mine, can't follow the fast-cut youtube videos. They just get lost. On the flip side tho I set them up with My Neighbor Totoro one day and the neighbor couldn't keep interest in it while my kid loved the whole 90 minutes. It was just too slow, compared to modern Disney.

        It's hard to identify variables in an anecdote, obviously, but somewhere between the less overall video time, the learning videos as distinct files rather than an endless flow on an app, and the much much more reading* my child is better able to follow both fast, high information density, youtube and slow emotional classics in a way that the neighbor with Disney+ and Netflix can't.

        *A 90 minute movie is incredibly short when compared with spending a few months working through all the Little House books [wikipedia.org].

          Our kids have been suffering from screen addiction since the pandemic began. We finally confiscated everything and instituted family reading time. Everyone lays on sofas and chairs in the living room together and reads something for an hour. They had severe withdrawal at first, but now enjoy it. Their behavior has been noticeably improving, too.

          It's interesting to see our societies developing a sort of social vitamin deficiency now that they have been deprived of essential human interactions for long periods of time. We do need to correct it immediately before we do permanent damage to our kids.
