Arriving in the morning
Morning arrivals usually reward people who land rested enough to stay functional all day. Light timing after arrival is still the main circadian signal.
Typical strategy
- Try for a main sleep block on overnight flights, usually 4 to 6 hours.
- Get local daylight after landing at a sensible time for your direction.
- Stay up to a normal local bedtime, usually around 21:30 to 22:30.
Rough threshold: if you have less than 14 hours between landing and target bedtime, aim for 4-6 hours in-flight sleep. More than 14 hours gives you more flexibility to adjust.
Concrete example
If you arrive at 07:00 after an 8 to 11 hour overnight flight, target 4 to 6 hours in-flight sleep, then stay awake until about 21:30 to 22:30 local. That gives you roughly 14-15 hours awake after landing, which is manageable with light and activity.
Common mistake
Skipping all in-flight sleep and then taking a long 2 to 3 hour nap around 16:00 can make the first local night much harder.
