Sponsor's own description

This research will explore the potential effects of Narrow-Band Ultra Violet B (NB-UVB) radiation on the intestinal microbiota composition and confirm a regulatory skin-to-gut axis during baseline conditions. Changes in the intestinal microbiota composition caused by NB-UVB phototherapy could be beneficial for patients with chronic/auto-inflammatory diseases like inflammatory bowel disease (IBD) by removing dangerous bacteria, increasing beneficial bacteria, and ultimately modulating immune responses.
