Controlled Clinical Trial
A compromise circadian phase position for permanent night work improves mood, fatigue, and performance.
To assess night shift improvements in mood, fatigue, and performance when the misalignment between circadian rhythms and a night shift, day sleep schedule is reduced. ⋯ Partial re-entrainment to a permanent night shift schedule, which can be produced by feasible, inexpensive interventions, is associated with greatly reduced impairments during night shifts.
