Exploring how visiting green areas affects the human microbiome

Transfer of Microorganisms Between Green Areas and Humans

NA · Universiteit Antwerpen · NCT06574724

This study is testing whether spending time in green spaces can change the bacteria on our skin and in our noses for both kids and adults.

What this trial studies

This study investigates the impact of visiting green areas on the human microbiome by analyzing microbial transfer. Participants, including children and adults, will visit a designated green space and engage in activities while providing microbiome samples before and after their visit. The study also aims to identify environmental, health, and lifestyle factors that may influence changes in the microbiome. By collecting swabs from participants' skin and nose, along with questionnaires, researchers hope to establish a connection between nature exposure and microbiome composition.

Who should consider this trial

Good fit: Ideal candidates include children aged 4 and older and adults in generally good health.

Not a fit: Patients with severe health conditions that limit their ability to visit green areas may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of how nature exposure influences human health and immune function.

How similar studies have performed: While the concept of microbiome changes due to environmental exposure is being explored, this specific approach of linking green area visits to microbiome analysis is relatively novel.
