NCT ID NCT07317349
First seen Jan 11, 2026 · Last updated May 24, 2026 · Updated 16 times
Summary
This study looks at how a small, daily time delay (like shifting your schedule by one hour each day) changes your internal body clock. Researchers will measure melatonin levels and reaction times in 40 healthy couples living in a lab for five days. The goal is to understand time perception and sleep rhythms, not to treat any disease.
