The norm in every other scenario is daylight during daylight hours. It is natural and normal for humans. Why should it be any different on board an aircraft?
How can you get jet lag when the time difference is only 2 hours?
Perhaps were trying to watch a film, read, work on their laptops, just keep cool? Maybe if you were in the window seat you may not have wanted sunlight blaring in.
I think you need to appreciate that 10/45 is quite. A big sample size
I have a feeling you’d be ranting if it was 8 hours difference but on arrival the difference between 9pm and 11pm assuming into bed at 11pm or 1AM could be a pain
