Summary

This trialtests the effects of varying sleep-wake schedules on volunteers over 27 days, with some randomized to a regular and some to an irregular schedule.

Who is the study for?
This trial is for healthy individuals with a Body Mass Index (BMI) between 18.5 and 29.5, who have not recently worked night shifts or traveled across more than two time zones. Pregnant women or those within six months post-partum, as well as anyone on medications, cannot participate.
What is being tested?
The study examines how varying sleep-wake schedules over a period of 27 days affects circadian rhythms, learning abilities, performance levels, and mood in participants. They will be randomly assigned to either a regular or irregular sleep schedule during their stay.
What are the potential side effects?
Since the intervention involves changes to sleep patterns rather than medication, side effects may include tiredness, irritability, difficulty concentrating or memory issues due to disruption of normal sleep.
