Late sleepers shifted their schedules two hours earlier in three weeks
Late sleepers shifted their schedules about two hours earlier in three weeks, according to a summary of the study.
The routine changed as a package: wake times, morning light, meals and activity moved earlier, while evening light stayed dimmer. That is a more demanding reset than simply trying to get into bed earlier, but the reported average shift was about two hours after three weeks.
