Jet lag seems to be the gift that keeps on giving, especially if you traveled halfway across the world. It tends to hang around for about 1 to 1½ days for every time zone you go across—so, if you flew over 12 different time zones, it’ll take at least 12 days before you feel back to your old self again.^{[1]

Research source} Traveling from west to east can also make your jet lag a little more challenging, since your body’s internal clock is losing hours instead of gaining them.^{[2]

This article is based on an interview with our travel specialist, Greg Guiteras, CEO of Lorraine Travel, LLC. Check out the full interview here.

1

Adjust your schedule to your new time zone.

It can be really tempting to take a snooze as soon as you start to feel drowsy—but catching zzzs in the morning, afternoon, or early evening won’t help your jet lag in the long run. Instead, do your best to eat and sleep at the same time as the locals.^{[3]

Nap for 30 minutes or less.

Long flights can be brutal, especially if you land bright and early in the morning. It can be tempting to hit the hay as soon as you step off the plane, but try to hold off if you can. A short, 30-minute nap is fine if you just need to recharge your batteries, but anything longer than that may make it harder for you to fall asleep later on.^{[5]

- Ideally, save your naps for late morning, early afternoon, or anytime that’s at least 8 hours ahead of your usual bedtime.

3

Get plenty of afternoon sunlight if you traveled east.

Being outdoors in the afternoon will help reset your circadian rhythm. Flying more than 8 time zones at a time can get a little tricky, since it’s easy for your body to confuse early evening light with early morning light. To be safe, stay inside during the morning in the first couple of days after your flight. Once the afternoon rolls around, feel free to head outside and soak in plenty of rays.^{[6]

- Slip on a pair of shades if you have to head outside in the morning. This way, your body won’t take in quite as much sunlight.
- Your circadian rhythm is your body’s internal clock—it lets you know when to fall asleep and when to wake up.^{[7]

Stay inside during the late afternoon if you headed west.

Head out during the earlier hours to help your body recognize your current time zone. Flying west definitely isn’t as difficult as flying east, but gaining 12 hours of time is still a big adjustment! Reset your internal clock during the first few days by heading inside a couple of hours before the sun sets.^{[8]

Take melatonin to help realign your sleep schedule.

Melatonin helps tell your body when to sleep and when to wake up. While your body produces melatonin on its own, taking melatonin supplements may help your body’s internal clock get back on track after a long trip.^{[9]

Stick with foods that you know.

An upset stomach is a common symptom of jet lag. Even if you’re feeling fine, it’s best not to take any chances during the first couple of days after you land. Instead, chow down on snacks and meals that you know and love rather than trying out the local specialties.^{[15]

Get some rest on the flight if it’s nighttime in your destination.

Sleeping on the plane can help you adjust to a new time zone. Think about it this way: if it’s nighttime at your destination while you’re up in the air, use your flight as an opportunity to catch some zzzs. That way, you’ll be “waking up” with the locals by the time you land.^{[22]

If you’re taking a trip east, hop into bed an hour before you usually would. If you’re jet-setting west, push your bedtime back by an hour instead. These small changes can make a big difference as you adjust to a 12-hour time zone difference!^{[25]
