Bright Light as a Countermeasure for Circadian Desynchrony

NCT01119365 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 300

Last updated 2022-04-06

No results posted yet for this study

Summary

Light is the primary means by which the internal circadian clock remains aligned ("entrained") with the external world. Misalignment of this internal clock can occur during situations such as shift work and jet travel across multiple time zones (jet lag). The purpose of this study is to examine how sequences of brief flashes of light can affect entrainment of the clock.
