Medical University of South Carolina·interventional·Posted Nov 6, 2024·Updated Apr 7, 2026

In Brief

A clinical study evaluating Re-Timer glasses and Placebo Device for Irritable Bowel Syndrome (IBS) and Circadian Misalignment. Completed, enrolled 5 participants across 1 site.

Detailed Summary

The purpose of this research study is to assess whether morning bright light therapy (BLT) using a wearable device called a Re-Timer could potentially improve Irritable Bowel Syndrome (IBS) symptoms and decrease intestinal permeability (leaky gut). Morning bright light therapy will be administrated through a safe-wearable glasses device called a Re-Timer. The Re-Timer glasses are lightweight and deliver blue-green light at 500nm, mimicking exposure to natural light.
