I don't know what the author is saying. His example of NYC to Rome is flying east and he recommends darkness in the morning. But then 2 paragraphs later, he says "Travel east and you’ll need morning light". I find the entire article hard to read, but I am pre-coffee right now. I find that I can go one night with minimal sleep and function just fine during the next day. So if I was going from NYC to Rome, I'd lift the shades in the early morning in Rome to make sure I'm super tired by the evening and go to bed at the correct time.
