Or the other way around: imagine you are the "owl" type (I'm not sure it is called this way in English; let's say https://en.wikipedia.org/wiki/Delayed_sleep_phase_disorder) and you are forced to live your entire lifetime in a sleep deprivation.
My life quality went up when I was able to push most lectures at the college from 10:40. In high-school, we were starting at the "standard" 8:00 and sometimes even 7:05.
If you are an owl, and live in the wrong (shifted west) time zone, it means you dont see sun in the morning (you dont want to wake up early.. say for a jog) and then you dont see the sun after work/school because you are screwed by being in the wrong time zone. Wrong time zone means no sun after work/school.
In Poland 15:30 and no sun in winter. In France (same time zone) there is sun at 17:30. So if you live in France you can get some sun.
Same works if you love across states in USA. The farther west the better for you.
