Jet lag and shift work

Robert E. Weir, Chad C. Hagen

Research output: Contribution to journalReview articlepeer-review


Jet lag disorder and shift work disorder result from extrinsic work and travel obligations in conflict with the intrinsic circadian rhythm. Poor seasonal or ambient light can prolong the time to adapt to either transmeridian travel or shift work. Symptoms of extrinsic circadian disorders are similar to those of other sleep disorders; namely sleepiness, fatigue, poor or irritable moods, or cognitive inefficiency. Misalignment and the secondary effects are usually temporary and reversed over a period of days to weeks, given sufficient opportunity to recuperate and reentrain.
