This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study investigates whether simple lifestyle changes — specifically adjusting your light exposure throughout the day and eating earlier in the evening — can improve sleep quality and how your body handles blood sugar. Researchers believe that syncing your daily rhythms (your body's natural 24-hour cycle) with your environment may help reduce cardiometabolic problems like insulin resistance and obesity.
Many young adults today sleep too little and have habits that don't match their body's natural rhythms, which may increase the risk of weight gain, diabetes, and heart disease. This study explores whether helping people realign their body's clock through light and eating patterns could be a simple, non-medical way to prevent these health problems.

You'll start with a week of monitoring your normal habits at home, then be randomly assigned to one of two groups for 8 weeks. If assigned to the intervention group, you'll receive counseling to increase morning light exposure, reduce evening light, and finish eating at least 4 hours before bedtime. Throughout the study, you'll wear a wrist device to track sleep and complete overnight visits at the lab to measure insulin sensitivity and your body's circadian rhythm. Both groups will have equal contact time with the research team.
