Eli5: how can a 14-15 hours flight trip can make you feel jet lagged but even a long 20 hours train journey doesn’t have the same effect?

Question

Is it because typically during these long flights there is a a change in multiple time zones and that messes your circadian rythm?

Answer 1

I’d like to throw in that *usually* the whole process of flying anywhere is inherently more exhausting than train traveling all together anyway on top of everyonee else’s timezone reason.
