Try Sleeping
If you’re on a long-haul flight, it is best to get as much sleep as possible. This is especially true on an overnight red-eye flight. Not only will it help you feel refreshed and ready to start your vacation upon arrival, but it will also help skip jet lag.
If you struggle to sleep on airplanes, the best way to go about it is by investing in a good travel pillow, earplugs (wax is better for noise cancellation), and an eye mask. This promotes uninterrupted sleep by blocking out all artificial light and loud noises.
Taking a low dose of melatonin can help flyers fall asleep and remain sleeping for a large duration of their flight. That being said, it should be avoided on trips shorter than 6 hours, as that is the average time it takes for the supplement to pass through the body.
Eating a carbohydrate-heavy meal (such as pasta) before or during an overnight flight can help travelers fall asleep. When the stomach is full, it can activate the parasympathetic nervous system which can cause sleepiness. Think food coma!
