This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are testing whether bright light therapy delivered through special wearable glasses called ReTimer glasses can help people with inflammatory bowel disease (Crohn's disease or ulcerative colitis). The study is based on the idea that light exposure affects sleep and inflammation in the gut. The researchers believe this treatment might reduce intestinal inflammation and improve how you feel.
Sleep problems are common in people with inflammatory bowel disease and may trigger disease flares. Scientists have discovered that poor sleep and disrupted sleep-wake cycles can make inflammation worse, so this trial is testing whether improving sleep patterns with morning light therapy could be a simple, safe way to reduce flares and help people live better with their condition.

You will first wear a watch-like device for 3 weeks to track your sleep patterns, and complete questionnaires about your sleep, fatigue, diet, and quality of life. Then you will be randomly assigned to wear either the special light-therapy glasses or placebo glasses (that look the same but don't emit light) for 60 minutes each morning for 4 weeks. After a break, you'll switch to the other type of glasses for another 4 weeks. Throughout the study, you'll provide blood and stool samples to measure inflammation markers.
