Who was the first person to experience jet lag? I assume it wouldn’t have been possible before fast air travel.
@grumpygamer Well, I would argue for the first person who suffered caffeine withdrawal, but that's a technicality, I'd say.
@grumpygamer Follow up question: Does the jet lag get worse the faster you go, or just the further you go?
@TacticalGrace_ @grumpygamer tbf, you could travel "in principle" 12 000 km from Svalbard to Cape Town without experiencing jet lag 🙃
@grumpygamer I wonder if it was possible to experience jet lag if you travelled for hours with a train at about 150-200km/h from East to West (or vice versa). If that was able to induce jet lag, it may have been experienced from around the mid 1930s when English and German steam engines reached that speed range.
@grumpygamer I guess if you're close to a pole, jet lag might be possible by ship.
@grumpygamer Quoting Wikipedia: “According to a 1969 study by the Federal Aviation Administration, aviator Wiley Post was the first to write about the effects of flying across time zones in his 1931 co-authored book, Around the World in Eight Days.”
@grumpygamer Maybe you could even be jet lagged when traveling on a fast Atlantic ocean liner. The westbound route to the US was done in about 4 days during the later parts of the great steam liners. I don't know if the day-night-cycle was already enough to get adjusted? Maybe you would be jet-lagged while still on board...

Presumably, if they weren't in steerage, many of those passengers would have been pretty well oiled with champagne during those four days which might have eased the transition.
@grumpygamer The great Italian author Umberto Eco wrote a fascinating novel on this topic (among many others), The Island of the Day Before. Set in the XVIIth century, it proposes that the soul can only travel one time zone per day, and having the soul separated from the body generates disconfort (a.k.a. jetlag).

Magellan's mate was surprised (the legend goes) when he found that the expedition's diary was one day off when he got back home. Does that count?

@JorgeStolfi @grumpygamer Well, that couldn't be Magellan, because he died before finishing the trip back to Spain. Maybe it was Elcano, who finished the expedition.

@grumpygamer

Also, theoretically if you are close enough to the North or South pole, you can cross several time zones on foot.

But of course there are several obstacles to experiencing jet lag in this scenario...

@grumpygamer The first person using a jet.
@grumpygamer for people who travel across the ocean by ship, how do they handle time? Do they keep the clocks on the time zone of the departure location until arrival? Do they gradually adjust each day?

@grumpygamer arguably the first transatlantic flight, not jet powered but 16 hours is short enough for jetlag to kick in.

The flight doesn't sound like the jetlag would have been their biggest problem though. https://en.m.wikipedia.org/wiki/Transatlantic_flight_of_Alcock_and_Brown

Also they flew from newf to Ireland, only 3.5h of time zone change if I understand right.
