Researchers find surprising revelation about popular daycare centers: 'Growing demand for ... these facilities'

A pioneering initiative in Finland is highlighting the profound impact of natural environments on children's well-being, from soil and moss to fungi. According to reports, 43 daycares nationwide have received funding to transform their outdoor spaces, allowing children to engage directly with diverse microbial life.

Researchers conducted an innovative study comparing children attending these "rewilded" daycares with those at traditional facilities featuring asphalt, sand, gravel, and plastic surfaces. Over the course of a year, results showed that kids in nature-rich playgrounds had fewer harmful bacteria on their skin and stronger immune responses.

Significantly, their gut microbiomes displayed lower levels of Clostridium bacteria, which are linked to inflammatory bowel disease, colitis, and infections such as sepsis and botulism. Another experiment revealed that simply playing in sand mixed with garden soil for two weeks improved children's immune system regulation.

Aki Sinkkonen, senior scientist at the Natural Resources Institute Finland, emphasized that "these nature-based interventions can help prevent imbalances in children's immune defenses," following the sandbox study.

These findings align with prior research showing that early exposure to green environments benefits immune and gut health. Other studies have demonstrated that spending time in nature, even for as little as 10 minutes, can support mental health in adults, and that children in greener neighborhoods are less likely to develop mental disorders later in life.

The Finnish approach has attracted attention from Norway, Iceland, and Denmark, as experts visit to explore how similar green daycare models could be implemented in their countries. "There is growing interest in establishing these nature-focused daycares in other towns," noted Marja Roslund, a scientist at the Natural Resources Institute Finland.
