A BBC report highlights research suggesting that touching natural materials such as soil, peat, moss, and tree bark can increase the diversity of microbes on human skin. Studies in Finland, including daycare experiments with forest-floor play areas, found higher skin microbial diversity and fewer potential pathogens after repeated contact with natural environments, with possible benefits for skin and immune health.
