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

The long-term objective of this proposed R24 program is to enhance our understanding of how circadian rhythm disruption contributes to vulnerability to alcohol-induced organ damage, and to explore the underlying mechanisms (e.g. microbiota) that could lead to the identification of novel therapeutic targets. This knowledge aims to inform the development of innovative strategies to prevent and to treat alcohol-related pathologies.
