Recruiting studies
- NCT07062315Enrolling by invitation
Timed eating based on your body clock for belly fat and health
This study tests if eating only during certain hours that match your natural sleep-wake pattern helps reduce belly fat and improve health in adults who are not very active and have extra weight around the middle.
Hong KongAges 18–65 - NCT07677111Recruiting
Chronotype alignment and time perception study
This study explores how your natural sleep-wake pattern (chronotype) affects the way you perceive time. If you are a clear early bird or night owl, you may be invited to attend one early-morning and one late-evening session.
Hong KongAges 18–55 - NCT07691866Recruiting
How sleep type affects balance and thinking
This study looks at how your natural sleep pattern (chronotype) might affect your balance and cognitive function. You will answer a questionnaire and do some simple tests.
Istanbul, IstanbulAges 18–35 - NCT02973412Recruiting
How sleep timing affects blood sugar in diabetes
This study looks at your daily sleep–wake timing (“chronotype”) and how it may affect blood sugar control in people with diabetes. It may help researchers learn whether sleep patterns could improve glucose levels.
LeicesterAges 18–75 - NCT06092411Recruiting
CBT and light therapy for depressed youth who are night owls
This trial tests if combining cognitive behavioral therapy (CBT) with bright light therapy (BLT) helps Chinese teenagers and young adults who have depression and a natural tendency to stay up late. The goal is to improve mood and sleep patterns.
Hong KongAges 12–20 - NCT06850428Recruiting
Alcohol recovery, sleep patterns, and activity levels
This study looks at how physical activity and your natural sleep-wake patterns (chronotype) relate to recovery from alcohol dependence. If you’re in remission and not currently drinking, researchers want to see how these factors affect your well-being.
Ankara, KeçiörenAges 18–65 - NCT07292597Recruiting
Circadian timing and time perception study for healthy adults
This trial looks at how your internal body clock affects the way you perceive time. It may help you understand your own sleep patterns and daily rhythms better.
AarhusAges 23–45 - NCT07410585Recruiting
Matching body clock to daily life for student well-being
This study tests if an app that helps match your daily schedule to your body's natural sleep-wake clock can improve well-being and happiness in college students. If you are a UCSD undergraduate with an Apple device, you may be able to join.
La Jolla, CaliforniaAges 18 years+ - NCT06941740Enrolling by invitation
Blood sugar dips and thinking in early or late sleep types
This study looks at how low blood sugar after eating affects thinking and memory in people who are either early birds or night owls. It may help understand if sleep type changes how your brain handles blood sugar dips.
Paderborn, North Rhine-WestphaliaAges 18–25 - NCT06916039Enrolling by invitation
Does breakfast type affect thinking in early or late risers?
This study tests how the glycemic index (how fast a food raises blood sugar) of breakfast affects memory and focus. It compares people who naturally wake early versus late, to see if the ideal breakfast depends on your body clock.

Common questions
- Are there clinical trials for chronotype?
- Yes. Clin2 currently lists 10 recruiting chronotype studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a chronotype trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a chronotype trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
