Summary

The goal of this study is to understand how visiting green areas affects the human microbiome through microbial transfer. Additionally, the project aims to understand which environmental, health and lifestyle factors can influence these microbiome changes. Participants will visit a green area, provide microbiome samples before and after the visit, and complete questionnaires related to environmental, health, lifestyle and demographic factors.

Detailed description

Several hypotheses propose that the modern surge in immune disorders is related to diminished contact with nature. Specifically, the Biodiversity hypothesis emphasizes that contact with natural environments enriches the human microbiome and is necessary for promoting immune balance. This project aims to investigate whether visiting green areas can contribute to changes in human microbiome composition. Additionally, the investigators aim to explore the environmental, health and lifestyle factors that can influence these microbiome changes. Adults and/or children will be asked to visit a green space (such as an urban park) and perform specific activities (such as walking or pushing a stroller) for a defined time period. Before and after this visit, swabs of their skin and nose will be collected to analyze microbiome changes. In addition, questionnaires will be administered to the participants, with the goal to align microbiome changes with environmental, health, lifestyle and demographic factors.
