Many millions of people experience the effects of jet lag every year


Jet lag occurs when someone travels rapidly across multiple time zones (e.g. in an airplane), causing sleep patterns to be temporarily impacted. In much the same way as with shift work (see the section on Shift Work), jet lag from rapid long-distance travel causes a desynchrony between circadian rhythms and the light-dark cycle, a temporary mismatch or misalignment between the external environment and our internal biological clock. Sufferers are therefore trying to sleep during the wrong phase of the circadian clock, either too early, too late, or at completely the wrong time of the day. In our modern world, hundreds of millions of people make long plane journeys every year, so the problem is ubiquitous, although many myths and misconceptions remain.
