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

Distance traveled on 20hr train ride at 50mph average = 1,000 miles (about 2 time zones)

Distance traveled on 14hr plane ride at 300mph average = 4,200 miles (about 6 time zones)
