With my 25-hour flight from Syd­ney back to Lon­don fast approach­ing, my mind is wan­der­ing to the topic of jet lag–or desynchronosis, to use the med­ical term.

The most often sug­gested reme­dies for jet lag (where recov­ery times are gen­er­ally said to be 1 day per east­ward time zone or 1 day per 1.5 west­ward time zones) are fast­ing for 11–16 hours before the flight or wear­ing sun­glasses (the lat­ter is what the British Air­ways jet lag cal­cu­la­tor is based on).

Not par­tic­u­larly a fan of these meth­ods, I con­cur with Bryan Caplan’s advice as he frames jet lag (and infant night feed­ings) in terms of fixed costs:

My alter­na­tive: Do not sleep on the plane.  At all.  When you arrive, do not sleep — at all — until a locally nor­mal bed­time.  Pay the fixed cost with­out cheat­ing.  When you wake up eight to ten hours later, you will be refreshed and in sync with your new time zone.  In exchange for less than a day of sleep depri­va­tion, you will feel fine for the rest of your trip.

This tech­nique has served me well for many years.
