To minimize jet lag when flying east, try to shift your sleep schedule a few days before departure, stay hydrated, and avoid heavy meals.
Quick answer
Adjust Your Sleep Schedule
Shifting your sleep schedule before you fly east can help your body adapt to the new time zone. A few days before your trip, start going to bed and getting up a little earlier each day. This brings you closer to destination time and softens the shock of the change.
Stay Hydrated
Dehydration can make jet lag feel worse, so drink water regularly during your flight. Limit sugary drinks, and avoid caffeine close to the time you plan to sleep. Bring an empty water bottle through security and refill it at the airport.
Avoid Heavy Meals
Heavy meals before or during a flight can cause discomfort and indigestion. Choose light, balanced meals or snacks that are easy to digest. Skip greasy or very spicy foods that can upset your stomach.
- Ask about melatonin: talk to your doctor or pharmacist before taking any new supplement.
- Get morning sunlight: natural light in the morning can help reset your body clock after flying east.
- Take a short nap: a 20-minute nap can help you feel fresher without leaving you groggy.
Pre-Flight Preparation
Adjusting Your Sleep Schedule
Start a few days before your trip. Move your bedtime earlier each night, by about an hour if you can manage it. Getting light early in the morning on these days can help your body clock shift in the same direction.
Preparing Your Body
Drink plenty of water in the days before you leave, and avoid heavy meals close to bedtime. A sleep mask can help you fall asleep earlier while it is still light outside. If you are heading somewhere dry, such as some of the places in Best Places to Travel in October: Where to Go and Why, plan to drink a little more on arrival.
Packing Essentials
- A travel pillow and eye mask for sleeping on the plane
- Earplugs or noise-cancelling headphones
- A portable power bank to keep your devices charged
- A change of clothes and basic toiletries in your carry-on in case of delays
- A sleep app or calming music to help you relax
In-Flight Strategies
Staying Comfortable
Seats over the wing often feel less bumpy in turbulence. If your budget allows, a higher cabin class gives you more legroom and recline. Wear loose clothing in layers, since cabin temperatures can change during the flight.
Managing Sleep
Set your watch to destination time when you board. Try to sleep when it is night at your destination and stay awake when it is day there. Use earplugs, an eye mask, or headphones to block out noise and light.
Making the Most of Amenities
- Use in-flight entertainment to pass the time during your "daytime" hours.
- Drink water often and go easy on caffeine and alcohol.
- Get up and walk around the cabin every few hours. Moving can help reduce stiffness and lower the risk of blood clots on long flights.
- Use the pillows and blankets the airline provides.
- Book a window seat if you want to sleep without seatmates climbing over you.
Post-Arrival Routine
Adjusting to the New Time Zone
Expect your body to take a few days to adjust, especially if you crossed many time zones. Eat meals and go to bed at local times from the first day. If you must nap, keep it short and early in the afternoon.
Staying Active
Light activity, such as a morning walk or gentle yoga, can help your body settle into the new schedule. Exercise can also lift your mood and energy levels. Avoid hard workouts close to bedtime.
Light Therapy
Natural light is one of the strongest signals for your body clock. After flying east, seek bright light in the morning and dim the lights in the evening. In winter, when daylight is short, a light therapy box can help. Ask a doctor first if you have an eye condition.
- Get outside in the morning, even for a short walk
- Take breaks to stretch and move during the day
- Avoid screens for an hour before bedtime
- Keep drinking water through the day
- Switch your phone and watch to local time and build a new routine quickly; planning ahead with Best Time to Book Flights in Advance: A Simple Guide can also give you more choice of flight times.
Timing is Everything
Timing matters a lot for eastbound jet lag. The best plan depends on your destination and how many time zones you cross.
Understanding Time Zones
Check the time difference between your departure and arrival cities. An online time zone converter makes this easy. Knowing the gap helps you plan how far to shift your sleep before you go.
Choosing the Right Flight Time
Many eastbound long-haul flights leave in the evening and land in the morning. On these flights, try to sleep as much as you can on board, then stay awake until a normal local bedtime. If you have a choice, a flight that lets you arrive and go to bed at a sensible local hour can make the first night easier.
Best Days to Fly
- Leave a rest day after you land before any important meetings or events.
- Avoid peak travel periods if you can, since crowded flights and airports add stress.
- Give yourself extra recovery time if you are flying a long way east.

Common Mistakes to Avoid
Not Adjusting Your Sleep Schedule
Flying east without shifting your sleep first can make the first days harder. Even moving your bedtime earlier for two or three nights can help.
Overeating and Dehydration
Large meals on board can upset your stomach and make sleep harder. Not drinking enough water can make you feel worse. Eat light and drink water regularly.
Other Common Mistakes
- Picking a poor flight schedule: choose a flight that lets you settle into local time quickly.
- Missing morning sunlight: morning light can help your body clock move forward.
