The Human Biome
The Human Microbiome, Gut Health and IEMT
The human microbiome influences emotional regulation, immune function, and resilience through the gut–brain axis and vagal communication pathways. Many of the chronic patterns observed by IEMT practitioners involve stress-related dysregulation that also affects microbial balance. By restoring autonomic stability and reducing stress reactivity, IEMT may indirectly support conditions associated with a healthier biome, contributing to improved digestion, sleep, immune resilience, and emotional well-being.
These pages explore how microbial life within the gut, skin, and broader environment interacts with emotion, cognition, and behaviour. Each section expands upon key aspects of the microbiota–gut–brain axis, offering practitioners scientific insight, ethical guidance, and integrative perspectives relevant to IEMT practice.
