Fasting May Fix Jet Lag

stoolpigeon writes "Reuters reports on a Harvard Medical School study on sleep patterns and how they relate to food. Researchers already knew that the sleep patterns of mice would change to match the opportunity to feed, but they did not know the mechanism that enabled the change. To find out, they looked for the part of the brain that was involved. They bred mice without a certain master gene that regulates the body's clock, and then targeted various parts of the brain with the gene, delivered in the shell of a virus. The results may, among other things, provide a new method for preparing to deal with jet lag: 'A period of fasting with no food at all for about 16 hours is enough to engage this [alternate body] clock,' the lead researcher said. The study appears in the journal Science."

      The real issue is which airline you are flying. Some are better than others. Unfortunatly, because national governments like to protect the dinosaur airlines from competition by better airlines (overseas carriers looking to enter the market, startups who think they can draw business away from the big boys), often the airlines that have the good stuff (better food, better seats, better entertainment etc) dont fly the route you want to fly.

      If aviation worldwide was deregulated and e.g. foreign airlines such as Singapore Airlines and QANTAS were allowed to fly domestic routes inside the US, the dinosaur airlines that offer the crappy service like United and American would have to get better or go bust.

      There's plenty of competition within the US as it is. You have to ask yourself why none of them have wised up and started offering better service. In fact the one that are doing the best tend to offer the worst amenities.

      The reason is that airline customers care about price above all else. I recall a study (no, I don't have a cite, sorry) where people would ignore significant differences in amenities for as little as a $5 difference in price.

      This is why service sucks everywhere. If an airline cuts food from a price and this allows them to undercut their competitor by some trivial amount, they get a significant influx of new customers. It becomes a race to the bottom, with costs cut on amenities everywhere to allow for reduced ticket prices.

      Because of this it's unlikely that Singapore Airlines or QANTAS would make much of a difference in the US market. They'd either have to do the same stuff in order to compete or they would get priced out of the market.

    Jetlag has not proven to be a significant issue with me or any of the people I have travelled internationally (as in, more than 5 time zones in one go) with. Is it only a significant issue to those who are changing timezone on an almost daily basis?

    Typically if you're travelling west, you just get an hour's nap (or not) on the plane, but stay up an extra 5 - 8 hours or so (or less and go to bed a bit earlier). That's pretty easy to do. You will tend to wake up a little earlier than normal, but that's not a massive deal.

    Travelling east is more difficult, as going to sleep 5 - 8 hours earlier is usually impossible (or impractical if still travelling) so you need to stay up an extra 8 - 12 or so hours, go to bed early, and get extra sleep that night. In both cases, you wind up waking up at roughly a sensible time.

    Perhaps there is a significant group (who I do not travel with) who are unable to stay up for 28 hours on the odd occasion when it's necessary to resync with the local time zone? Or is it that if you do it, say, every week, this technique becomes totally impractical?

    The idea is to start pushing your food cycle toward the target before you fly so your body is more receptive to the time change.

    In fact, if you're taking the typical ATL-ICN-HKG route some airplane dining is going to be pretty important. You'll arrive in Hong Kong around 10 p.m. Your elapsed clock time including layover will be nearly 24 hours, and if you manage your eating and sleeping during that time you'll actually be in pretty good shape the morning after your arrival. (Hint: Sleep as much as possible between ATL and mid-Pacific, and only after that should you turn on the entertainment system.)
