Jet lag is unavoidable on long-haul flights across multiple time zones, but a few practical steps can significantly shorten how long it takes your body to adjust.
Before You Fly
Gradually shifting your sleep schedule a few days before departure, even by an hour or two, gives your body a head start on adjusting to your destination’s time zone.
During the Flight
Setting your watch to the destination time zone as soon as you board, and eating and sleeping accordingly, helps mentally reset your internal clock before you land.
After Landing
Getting outside in daylight as soon as possible after arrival is one of the most effective ways to reset your circadian rhythm, alongside resisting the urge to nap during local daytime hours.

Practical Tips
- Stay hydrated throughout the flight – cabin air is notably dry, which worsens fatigue.
- Limit alcohol and caffeine on the flight – both interfere with your body’s ability to adjust.
- Book a flight arriving in the evening if possible, so you can go straight to a normal night’s sleep.
FAQ
How long does jet lag typically last?
Roughly one day per time zone crossed, though individual recovery time varies.
Do jet lag supplements actually work?
Results vary by individual – melatonin has some supporting evidence for helping reset sleep cycles.
Is it better to arrive during the day or at night?
An evening arrival that leads straight into a normal night’s sleep tends to work best for most travelers.
Final Thoughts
Jet lag can’t be eliminated entirely on long-haul flights, but adjusting your schedule before departure and getting daylight exposure on arrival meaningfully shortens recovery time.
