How to Handle This Route
For US to Europe jet lag, shift sleep earlier before departure, sleep on the overnight flight if possible, seek morning light after arrival, and avoid long arrival-day naps.
Light
Prioritize outdoor morning light in Europe. In the evening, dim screens and room lights so your body clock can advance toward local bedtime.
Sleep
Treat the flight as a short night. Use an eye mask, keep meals light, and avoid turning the arrival day into a long nap day.
Flight
An evening US departure with a morning Europe arrival works best when you sleep soon after meal service and switch your watch to destination time early.
