You have to sleep when it’s night wherever you are now. If you land in the morning and are really, really tired, you may want to take a power nap, which should never last for more than an hour. You’ll have some extra energy to be a tourist and explore the city, ensuring that you’ll have no problem to fall asleep at 10 p.m. local time.
