We have been back in Holland now for two days, but still it is difficult indeed to shake off this aggravating thing called jetlag. What is jetlag anyway? Basically, jetlag is caused by crossing over multiple timezones in a short period of time. While your biological clock is based on a certain timeframe, by quickly shifting to another timeframe, the human body takes time to acclimate. While you are in California where it is six in the afternoon (dinner time), your inner clock still set to Dutch time may be telling you that it is three in the morning (REM time). It is time to eat a pile of Mexican food but your body is telling you that it is time to sleep.
You feel tired and cannot concentrate, have dry eyes and throat, and easily become irritated and/or irrational. In addition, it is hard to sleep becuase your periods of slumber are short and light, and you suffer broken sleep because you are either waking up all the time, or too early. All in all, not much fun.
So the four of us were all wide awake last night and could not sleep. In a way it was kind of funny. The two parents and two kids hanging around with all the lights on at two in the morning, reading and talking to pass the time. In a way, it was almost like a slumber party, and the fact that the vacation memories were still fresh in our minds made us feel in a good mood despite the discomforts. Fortunately I did not have to go to work in the morning. I slept until noon, believe it or not.
