Brief 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.

Outcome Measures
Primary Outcomes (1)
Microbiome changes
Microbiome sequencing will be performed to assess changes in microbial community composition of nasal and skin swabs, focusing on abundances and diversity of different microorganisms and their genes
Two time points directly before and after the intervention (on 1 day)
Secondary Outcomes (2)
Specific microorganisms within the skin and nasal microbiomes
Two time points directly before and after the intervention (on 1 day)
Associations between the human microbiome and environment
Two time points directly before and after the intervention (on 1 day)
Other Outcomes (3)
Self-reported lifestyle
One time point directly before or after the intervention (on 1 day)
Self-reported health
One time point directly before or after the intervention (on 1 day)
Self-reported demographic information
One time point directly before or after the intervention (on 1 day)
Study Arms (1)

Interventions
Participants are asked to visit a green space for a defined time period
