How to Deal with Jet Lag: Science-Backed Tips for Faster Recovery

Jet lag occurs when your internal clock (circadian rhythm) is out of sync with your destination's time zone. It takes roughly one day per time zone crossed to fully adjust. Eastward travel is harder than westward because it shortens your day. Symptoms include fatigue, insomnia, digestive issues, and difficulty concentrating.

Before Your Flight

  • Shift your sleep schedule 1 hour per day toward your destination's time zone for 3 days before departure
  • Stay well-hydrated in the days before flying
  • Get plenty of sleep the night before -- do not try to "pre-tire" yourself
  • Set your watch to destination time when you board
  • During Your Flight

  • Drink water constantly (dehydration worsens jet lag)
  • Avoid alcohol and caffeine in the last 4 hours of your flight
  • Sleep if it is nighttime at your destination, stay awake if it is daytime
  • Move regularly -- walk the aisle every 2 hours
  • Use a sleep mask and earplugs for rest periods
  • After You Arrive

  • Get sunlight exposure as early as possible -- natural light resets your clock
  • Stay awake until local bedtime even if you are exhausted
  • Eat meals at local times to signal your body to adjust
  • Take a short 20-minute nap if desperate, but set an alarm
  • Exercise lightly (a walk or gentle jog) to boost energy
  • When to Use Melatonin

    Melatonin supplements (0.5 to 3 mg) taken at your destination's bedtime can help reset your clock. Start the night you arrive and continue for 3 to 4 nights. Consult a doctor if you take other medications. Melatonin is most effective for eastward travel crossing 5 or more time zones.
