Starving for a Jet Lag Remedy
By Ricardo
Jet lag hits me harder than a jalapeño margarita. I don’t mean, simply, restless sleep for a night or two after a long (trans-Pacific) flight, but all encompassing type of jet lag: dizziness, inability to sleep more than four hours for up to six days, nausea, the acute awareness that my mind and body are not in sync—the full-on zombie enchilada. This condition is realized at least a couple of times a year—for about eight years now. So, I’m way weary of this dilemma. When I fly from Los Angeles to the far east, and especially when I travel west to east on my return trip (the mother of all hellish routes—jumping 15 time zones) I know I’ll be out of commission for at least five, maybe six, days. I simply dread it. My curiosity was, therefore, quite peaked when I read a recent on-line article (Starving yourself may fend off jet lag) announcing a Harvard University study about the relationship between one’s internal clock and how it is affected by meals. In a nutshell, it concluded that fasting during long flights may trick one’s body into lessening the impact of jet lag.
Let me state, first of all, that I am not one of those new-age, holistic, “power-cleansing” type of guys. To me fasting means missing a meal. And since the Science study stated that one should fast at least sixteen hours of the flight time from their example set forth (Tokyo to Los Angeles), I had to seriously equate—what I was sure would be a torturous ordeal—with the benefit of not having to suffer five to six days of feeling crappy afterwards. I decided, in the interest of jet lag-relief science, to be the lab rat and test out this so-called remedy.
Last week I flew from Bangkok to Los Angeles. My flight departed at 5PM. At the airport, right before the first leg of my flight (there would be a quick plane change in Taipei), I ate a big meal. This would be my last meal for 18 hours. Additionally, I followed another common remedy which is to not sleep—an option not mentioned in the study, but seem equally logical to me. “Yeah, right”, you are no doubt thinking. “No food and no sleep on a (combined) flight of 15 hours, that’s not possible.” But, I did it. No food at all, just lots of water. And after about five hours of flight, my hunger actually dissipated. It was like my brain was saying “Oh, it’s past dinner time. You must no longer be hungry.” And by the time the plane was about to land, I had also noticed that I was not nearly as tired as I should have been. I was landing in Los Angeles at 8PM and my body was feeling like a person that was (more or less) 8PM tired (granted after an exceptionally hard day) and only a couple of hours late hungry.
That first night in Los Angeles I wolfed down two plates of pasta, had half a glass of red wine and went to bed at about midnight—my normal time. The following morning I woke up at 6AM. I felt rested and not at all loopy. This, however, did not convince me that I’d dodged a bullet. My jet lag usually does not hit me until several days after the flight. But the fact that throughout that first full day back I was, for the most part, clear headed and energetic was promising. I was even able to get quite a bit of work done on the computer.
The second night’s sleep, however, was not as sound. I got in only about 5 hours—but that could have had something to do with going out to a 3rd street tequila bar with my hosts. That second day I was a little more tired than the first day—due to not getting my full eight in, not the tequila—but, still little jet lag was felt and I was still able to work several hours. That night I slept six hours and the following day (day 3), at around 6PM, I felt like taking a serious power-nap. But as I laid there on the sofa of my friend’s home, with my head begging for some nap time, my body was not concurring. I could feel how out of sync the two were. So, I sat up and forced myself to stay awake. An hour later, and after a couple of episodes of Family Guy, I was no longer sleepy. That night I slept for nearly 8 hours. And on the fifth night back, I again slept well. On day four—the day I’m usually impacted the hardest by a trans-Pacific flight—I still felt pretty good, even though I had flown eastward another two time zones that day. That night I slept nearly nine hours and that day I declared myself jet lag free.
Conclusion? The combination of fasting and not sleeping during a long flight makes a big difference. As sensitive as I am to jet lag, it was a relief this time to have gotten past it with relative ease. Yes, there was still some residual jet lag, but only about half (perhaps even less) as severe as in previous years. So, on your next long flight, starve yourself. What do you have to lose?
