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 (east-west or west-east) travel on a (typically jet) aircraft. It is classified as one of the circadian rhythm sleep disorders.
Symptoms
The symptoms of jet lag can be quite varied, depending on the amount of time zone alteration, time of day and the susceptibility of individual differences. Sleep disturbance occurs, with poor sleep upon arrival, sleep disruption including trouble falling asleep (if flying east), early awakening (if flying west) and interrupted sleep with multiple awakenings and trouble remaining asleep. Cognitive effects include poorer performance on mental tasks and concentration, increased fatigue, headaches, and irritability, and problems with digestion including indigestion.
Causes
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 travellers. 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.
