But everything else shifts by an hour too? I literally don't even notice the clocks change these days until I look at a non-connected clock, everything connected to the internet just shifts automatically, alarms and all. An hours difference shouldn't put a healthy human out so much.
yes it does because a healthy human has a well established circadian rhythm that is adjusted to the cycle of day and night.
Humans adaptability is what makes us different from animals who treat this stuff as second nature and are straight into their warrens, dens, etc the moment the sun goes down. A circadian rhythm in a human should allow for an hour's shift either way. Otherwise we would never have been able to migrate and spread around so many different parts of the world with different daylight cycles to begin with.
And how fast do humans wander on foot? Consistently, with cargo and so on maybe 30 km a day. An hour difference is 15 longitudes. In europe a longitude is about 70, at the equator about 110 km. So it takes 1050 km or 35 days to naturally move an hour in Europe and 1650 km or 55 days at the equator.
Until evolution catches up to modern means of transportation or doing something like the time switch it will take millenia at least. And on top of that we also need to adapt to the 9-5 rhythm instead of getting up with the sun and to bed with sunset, like we did for hundreds of thousands of years.
And if you say that for you it is easy, that might be true, but for most people it is not and shouldn't be. Finally i'd recommend you to have a look at the health effects of shift work, in aprticular working night shifts. It fucks peoples health significantly.
