How to sleep better during a flight

Choose the right seat

A seat by the window offers a surface to lean against and reduces interruptions from those in the aisle who need to get up multiple times during the flight. If the route includes a meal, a seat further back in the cabin, where service often arrives with less delay, also allows you to fall asleep sooner.

Accessories that really make a difference

A quality neck pillow, earplugs, and a blackout mask block the three most common disturbances preventing sleep: uncomfortable position, noise, and light. It's worth trying multiple positions with the pillow instead of always relying on the same one, because effectiveness varies greatly from person to person.

Manage caffeine and meals in the hours before

Caffeine has a half-life of about 5-6 hours: consumed even in the early afternoon can interfere with sleep on an evening flight, so it's best to avoid it well before takeoff if the goal is to sleep onboard. Similarly, a heavy meal in the hours immediately before slows digestion and makes it harder to relax enough to fall asleep.

Synchronize sleep with your destination's time zone

When possible, sleeping according to the arrival location's time instead of the departure one reduces jet lag impact once you land. To understand why falling asleep at altitude remains more difficult than on the ground even when following these precautions, the article on sleep physiology in flight explains the mechanisms involved.

If you have an evening flight, the step with the most immediate return is stopping caffeine intake at least 6 hours before boarding: it's the easiest variable to control and among the most underestimated.
