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.
Summary written for real people, not researchers, by Clin2.

This study explores how your internal body clock and sense of time change during 36 hours of staying awake. You will stay in a lab and complete simple tasks to help researchers understand the link between circadian rhythms and time perception.
This study looks at how a small, consistent delay in your daily schedule affects your body's internal clock. It involves you and your partner staying together in a lab for five days.
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.
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 the timing of meals (and daily timing habits) affects your body’s natural clock and related health measures. It involves healthy, generally low-risk participants and may help researchers understand how timing affects metabolism and sleep.
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.
