Most travelers try to make the most of their limited time overseas, yet fail to take into account the leap in time zones they make in a matter of hours. It can take your body's internal clock several days to catch up to that leap, and in the meantime you’re likely to experience the disruption of your sleeping and waking cycle known as jet lag. Symptoms of jet lag include sleepiness during the day, insomnia at night, poor concentration, confusion, hunger at inappropriate times or lack of appetite, and general malaise and irritability. Here are our top tips to fight jet lag.
1. Adjust your internal clock.
Several days (at least four) before departure, gradually shift your sleeping and eating times to coincide with those at your destination. Once you arrive, adopt the local time for your daily routine.
2. Opt for overnight flights.
You’ll have dinner at a normal time and be much more likely to sleep than on an afternoon flight. Depending on the length of the flight and the number of time zones you cross, you’ll arrive at your destination in the morning or afternoon. This is the best way to replicate your normal schedule, and it’ll be easier for you to reset your clock.
3. Curtail coffee.
For 12 hours before, as well as during, your flight, avoid overeating and caffeine. Although caffeine can help keep you awake longer, it makes you wake up more often once you do fall asleep and so reduces total sleep time.
4. Stay hydrated.
Drink at least 8 ounces of water for every hour you’re in the air—even if you don’t feel thirsty. If you wear contact lenses, clean them thoroughly before your flight, use eye drops in the air, and consider removing your lenses if you nap. In your carry-on pack a bottle of moisturizing lotion, lip balm, and a hydrating spray with essential oils (not just water) to spritz your face with occasionally. Just be sure all toiletries are TSA compliant.
5. Avoid or limit alcohol inflight.
Cabin air dehydrates passengers, and altitude changes can quicken the effects of alcohol (the rule of thumb is one drink in the air is the same as two or three on the ground). A cocktail may relax you, but it's also apt to dry you out, and even worsen symptoms of jet lag.
6. Try to sleep on the plane.
This is especially important when you’re traveling overnight or flying west to east. Travel is extremely tiring, and the more rest your body gets en route the more prepared you’ll be to deal with the stresses of jet lag. If you’re taking a very long flight—United States to Asia, for example—consider saving up enough dollars or frequent-flier miles to fly business or first class, as it’s a lot easier to sleep when your seat reclines all the way back. If you can’t avoid coach, opt for a window seat and bring enough padding (pillows or something that can act as such) to prop yourself up against the wall.
7. Use sleeping pills wisely.
A pill with a short cycle may be helpful on overnight flights. Make sure, however, that you time the dosage correctly or you may be very groggy when you land. Also, an airplane is not the place to try out a pill for the first time, so only take medications you are already familiar with.
8. See if melatonin is for you.
Consider taking the nonprescription drug melatonin. Research suggests that the body uses this hormone to set its time clock. Because melatonin seems to control when we go to sleep and when we wake up, a number of scientists advocate supplements to alleviate jet lag. Some (but not all) studies suggest that taking 3 milligrams of fast-release melatonin prior to bedtime for several days after arrival in a new time zone can ease the transition.
9. Get outside.
After arrival, spend a lot of time out in the sunlight, which will help your body reset its natural time clock to coincide with your new surroundings.
10. Don’t drift off too early.
Unless you arrive at your destination at night, and reasonably close to a normal bedtime, don’t go to sleep as soon as you reach your hotel. Unless you’re used to taking regular short naps at home, you’re better off staying up until bedtime: If you’re really exhausted from travel, a 20-minute nap could easily become a three-hour nap, which will disrupt your sleep schedule even more—you might find yourself wide awake at 4 AM.
