According to Wikipedia Jet lag is medically referred to as "desynchronosis," a physiological condition which is a consequence of alterations to circadian rhythms; it is classified as one of the circadian rhythm sleep disorders. Jet lag results from rapid long-distance transmeridian (east-west or west-east) travel, as on a jet plane.
Translation: Feeling like "ass" for a week+ upon arrival. Having travelled overseas before and moved back and forth across Canada numerous times, Jet lag was nothing new to me. However, moving 15 hours ahead threw everything I knew out the window. My first assumption was that adjusting our sleep schedule would be the difficult part… wrong again. Instead the first week felt passed under a permanent haze and a constant state of delusion. Combined with the heat and humidity I was one hot mess for the first week. The time change has also turned us into little old ladies, struggling to make it to 9:30pm each night before falling asleep (On second thought for those of you that know me, maybe this isn't all that different than when I was in Canada).
Jet lag certainly adds a new dimension into your first days of work in a new job. Not only do you have to overcome the demands of figuring out a new organization, attempting to remember a never ending stream of new work contacts, and making a good first impression, you must also come to terms with the physical effects of jet lag.
All I can say is that I will be glad when these first few transition weeks are over (though I have feeling with this humidity I will still be a hot mess for the coming months ahead).
