Light, sleep, and body clock study for adults
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 85 years old
- You are in generally stable health

This study tests whether changing the light in a hospital room can improve sleep and help your body clock work better in older adults. It may be most helpful if sleep problems or irregular daily rhythms are affecting you in the hospital.
This study tracks your body's daily rhythms using a wearable device and saliva samples. It includes healthy people and those with sleep apnea or insomnia.
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 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 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 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.
