Study Summary

This trial aims to study how the body's internal clocks, known as circadian rhythms, are affected by changes in exposure to light and meal timing. By analyzing proteins in the blood and saliva, researchers

Who is the study for?

This trial is for individuals interested in participating in a study about body clocks and how they are affected by changes similar to jetlag. The details on who can join are not provided, but typically participants need to be healthy with no major medical conditions that could affect their circadian rhythm.Check my eligibility

What is being tested?

The study is testing how simulated jetlag affects proteins in blood and saliva that indicate the timing of our internal body clocks. It aims to understand how light exposure and meal times influence these biological rhythms, potentially leading to new treatments for real-life jetlag.See study design

What are the potential side effects?

Since this trial involves a simulated jetlag protocol rather than medication or invasive procedures, side effects may include temporary sleep disturbances, fatigue, or mood changes due to the alteration of normal sleep-wake patterns.

Experimental Treatment

Group I: Meal timingExperimental Treatment1 Intervention

Three days of meals, bedtimes and wake times scheduled to occur 5h earlier.

Group II: Bright lightExperimental Treatment1 Intervention

Three days of exposure to bright light of ~3,000 lux, which is less than one-third the brightness of a sunrise or sunset (timed to start earlier by 1h each day) with scheduled bed and wake times timed 5h earlier.
