A physical condition caused by crossing time zones during flight; often the result of disruption to the circadian rhythms of the body.
Jet lag, medically referred to as desynchronosis, is a physiological condition which results from alterations to the body's circadian rhythms resulting from rapid long-distance transmeridian travel on a aircraft. It is classified as one of the circadian rhythm sleep disorders. The condition of jet lag may last several days until one is fully adjusted to the new time zone, and a recovery rate of one day per time zone crossed is a suggested guideline. The issue of jet lag is especially pronounced for airline pilots, crew, and frequent travelers. Airlines have regulations aimed at combating pilot fatigue caused by jet lag. The common term jet lag is used because before the arrival of the passenger jet aircraft, it was generally uncommon to travel far and fast enough to cause jet lag. Propeller flights were slower and of more limited distance than jet flights, and thus did not contribute as widely to the problem.
