It gets worse once airborne. There, one is frequently told to engage in two mutually exclusive activities: glug water constantly and sleep as much as possible. Maybe this works for people with an iron bladder and sleeping superpowers. Ordinary mortals can forget it, especially those in steerage.
Speaking of which, there is a special brand of unhelpful advice from chief executives such as Yang Yuanqing, chief of the personal tech group Lenovo.
“Choose a midnight flight and take a good nap on the plane,” he told China Daily. This makes sense if you have a bottomless supply of business class tickets. Sadly I do not, which is a shame because I have reluctantly concluded that by far the best weapon against jet lag is a seat in business.
In its absence, I have three other tips. Breaking up the flight with a stopover is by far the best. I had never tried this until an Australian friend based in the Middle East said he swore by it, normally stopping at an airport hotel for long enough to get eight hours’ sleep before hopping back on the plane. It obviously takes more time and money, but rarely as much as an upgrade. It won’t work for my flight to Chile, sadly, because I have to fit in with other people’s travel schedules. But having just done it in Dubai, after which there has been no repeat of the pen embarrassment, I am a convert.
My second tip is from another road warrior friend: act like a new mother. Snatch sleep whenever and wherever possible, regardless of the time in your destination. It does not work as well as a stopover but still helps.
Finally, forget all the guff about resetting your body clock with light, melatonin or whatnot and concentrate on doing it with food. Eat as little as possible at the airport and on the plane, then tuck in at the first meal time in your destination, preferably breakfast at least 14 or so hours later.
I came across this ploy fairly late in life from a chef and wish I had discovered it sooner because it is far easier than it sounds and curbs the worst of jet lag. There is even research to back it up, though admittedly it was done on mice.
I do not claim to be the last word on all this. Suggestions on other useful remedies will be gratefully received, as long as they work in economy and preferably if they come this week.
