How to Beat Jet Lag in 3 Days

Beat jet lag by shifting your schedule 3 days before departure, controlling light exposure, and staying hydrated. Skip sleeping pills and alcohol. Most people adjust within 72 hours using this method.

  1. Start shifting 3 days before you leave. For eastward travel: Go to bed 1 hour earlier each night and wake up 1 hour earlier. For westward travel: Go to bed 1 hour later and wake up 1 hour later. Eat meals at your destination's schedule starting 2 days before departure.
  2. Control light exposure during travel. Download a jet lag app like Timeshifter ($9) or use NASA's free calculator. Wear sunglasses when the app says avoid light. Seek bright light when it says get light. This is the most important step.
  3. Set your watch immediately. Change your watch to destination time as soon as you board the plane. Start thinking and acting in that time zone. Eat and sleep according to your new schedule, not your body's signals.
  4. Handle your first day strategically. Land in the morning? Stay awake until 9 PM local time, no matter how tired. Land at night? Try to sleep on the plane and get morning sunlight immediately after landing. No naps longer than 20 minutes for the first 3 days.
  5. Use melatonin correctly. Take 0.5-3mg of melatonin 30 minutes before your destination's bedtime. Only use it for 3-4 days maximum. Don't take it randomly - timing matters more than dosage.
Does the direction I'm traveling matter?
Yes. Eastward travel (losing time) is harder on your body than westward travel (gaining time). Expect an extra day of recovery when flying east across multiple time zones.
How many time zones before jet lag becomes a problem?
Most people feel jet lag after crossing 3+ time zones. The rule of thumb: expect 1 day of recovery per time zone crossed when traveling east, slightly less when traveling west.
Should I sleep on the plane?
Only if it's nighttime at your destination. If you land in the morning, try to stay awake on the flight. If you land at night, sleep on the plane if possible.
What about caffeine?
Use caffeine strategically. Have your morning coffee at your destination's morning time, not your home time. Cut off caffeine 6 hours before your destination's bedtime.
