As the traveling season gets nearer, maybe you have some lovely, exciting plans to fly someplace distant across several time zones. In that case you’ll have to contend with jetlag, and if you do, I want to share a cool tip I first heard about from my friend Adam, who himself picked it up from Jason Kottke.
The advice is simple: you should fast for 12 to 16 hours before breakfast time at your destination.
The reasoning is that the digestive system plays a significant role in our body’s perception of time. This voluntary fast is meant to mimick an overnight fast (minus the midnight munchies) and helps to set the body’s internal clock to the new time zone.
I happened to read about this just before we left to spend some time in San Francisco in the fall, and since we were about to embark on a round trip of 12-hour flights with 9-hour time differences, I was quick to recruit myself as a guinea pig to test the technique.
And I’m thrilled to report it worked really well: I sailed through the time difference with just about the same effects I get from taking the metro, even though I got virtually no sleep on the plane, thanks to a very sweet, but very alert little boy sitting on my knee.
It was very easy to put in practice, too.
