Sleep, light, and body clock study in healthy adults
Part of Brain & nervous system clinical trials.
This study looks at how sleep, light exposure, and your body's internal clock affect oxidative stress (a type of cell wear and tear). It may help researchers understand what keeps our cells healthy.

This study looks at how your eyes react to light and how that relates to your sleep and daily body rhythms. It may help researchers understand sleep problems and find better ways to treat them.
This study looks at how non-visual light (light that isn’t just for seeing) affects your sleep timing and circadian rhythms, and whether the effects differ by sex and age. It may help researchers design better light-based or sleep-support strategies in the future.
This study uses a light-based test (the “photomotor reflex”) to see how non-visual effects of light may affect sleep-wake timing, brain function, mental health, and eyesight. You may be assigned to a group based on your condition, or you may be in the healthy control group.
This study tests how different colored lights affect people’s responses and comfort. It does this by comparing your experience under colored lighting conditions in a controlled setting.
This study looks at how eating at night affects your sleep and body clock. You will spend two nights in a sleep lab to test the effects of a small meal before bed.
This study tests whether different colors of light change how your body or brain responds. You may be asked to spend time under specific lighting while researchers measure outcomes.
