8 Ways to Get Over Jet Lag

Jet lag has a way of stealing the excitement from a well-planned trip. When you cross several time zones, your internal clock, your circadian rhythm, falls out of sync with your destination, leaving you groggy, foggy, and wide awake at 3 a.m.

There's no instant cure, but you can absolutely take practical steps to feel better faster. Below, we've gathered eight science-backed strategies to help you get over jet lag, plus answers to common questions about how long it lasts and whether you can prevent it altogether.

1. Adapt Quickly to Your New Time Zone

The faster you sync with your destination's schedule, the sooner your symptoms fade. As soon as you land, adopt the local sleep-wake schedule, even if your body protests.

Crossing more than three time zones increases your likelihood of jet lag, and the more you cross, the harder it hits. Direction matters too.

If you're flying east to west, ease into it by going to bed later and waking later for a few days before departure. Heading west to east? Do the opposite.

Adjusting your meal schedule ahead of time helps as well. Apps like Timeshifter, which builds a custom jet lag plan based on your flight details, sleep pattern, and chronotype, can make the timing far less confusing.

2. Manage Sleep Time

Quality sleep is your strongest tool against jet lag. Start before you even leave: get plenty of uninterrupted rest in the nights leading up to your flight, since sleep debt only makes symptoms worse.

On the plane, try to sleep as if it's already your destination's local time. When you sleep on board, plan it around your arrival schedule rather than the clock you left behind. Once you land, nap whenever drowsiness hits, but keep naps short so they don't sabotage nighttime sleep.

Be realistic, though. Sleep snatched in a cramped airline seat or on an airport bench will never match the quality of a night in your own bed. Cabin noise, dry air, dim-but-not-dark lighting, and constant interruptions all fragment your rest. Think of in-transit sleep as damage control rather than a cure. It softens the worst of the fatigue and helps your body start recalibrating its internal clock, but you'll still need a proper night's rest at your destination to feel fully back to normal.

3. Drink Water

Long flights are surprisingly dehydrating, and dehydration amplifies fatigue and headaches that mimic jet lag. Drinking plenty of water before, during, and after your flight helps combat those effects.

Keep a refillable bottle handy and sip steadily rather than waiting until you feel thirsty. If you have any doubts about water safety at your destination, choose bottled water. Just as important is what to avoid: both alcohol and caffeine are diuretics that pull fluid from your body and can leave you feeling worse. Staying hydrated also eases general travel fatigue, so it's worth the extra trips to the restroom.

4. Eat Smaller Meals

Heavy meals can burden a digestive system already thrown off by travel. Eating small meals more frequently, and choosing lighter foods like fruit and vegetables, tends to feel gentler on your stomach.

For the first day or two, stick with foods your body already knows how to digest. Familiar meals reduce the odds of bloating, cramping, or other digestive discomfort that often tags along with jet lag.

Keep it simple: eat light, eat often, and skip the experimental menu until you've adjusted.

5. Use Light Strategically

Light is the most powerful influencer of your circadian rhythm, and the stimulus that resets your internal clock is light entering the eyes, especially the blue-rich spectrum found in daylight. The catch is that timing determines whether light pulls your clock in the right direction or the wrong one.

The basic rule follows your direction of travel:

• Flying east (you need to shift earlier): seek bright light in the morning at your destination and avoid it in the late evening.
• Flying west (you need to shift later): seek light in the late afternoon and evening, and avoid bright light first thing in the morning.

One important exception: if you've flown east across more than eight time zones, very early morning light can backfire. Your body still reads that hour as the middle of the night, so it delays your clock instead of advancing it. Wait two to three hours after local sunrise, then get outside.

Can't get outdoors? A bright lamp or light therapy box offers similar benefits in a pinch. Pair well-timed light exposure with an adjusted sleep schedule and you'll retrain your rhythm considerably faster.

6. Drink Caffeinated Beverages

Used thoughtfully, caffeine can help you power through daytime drowsiness while your body catches up. A caffeinated beverage in moderation may boost alertness when you're fighting the urge to nap at the wrong hour. Keep in mind, though, that caffeine is an alertness aid rather than a clock-resetting tool: light and melatonin do the heavy lifting, and research suggests an evening dose can actually delay your internal clock by roughly 40 minutes.

Because of that delaying effect, the best time to drink it depends on which direction you flew:

• Flying east (you need to shift earlier): confine caffeine to the local morning. An afternoon or evening cup works directly against the phase advance you're trying to achieve, pushing your bedtime later precisely when you need it earlier.
• Flying west (you need to shift later): caffeine is more forgiving here, and a cup in the early afternoon can help you stay awake until the later local bedtime instead of fading at 6 p.m. Still, stop well before you plan to sleep.

As a general rule, cut off caffeine at least six to eight hours before your target bedtime, or by early afternoon if you're sensitive to it. Think of caffeine as a short-term crutch, not a substitute for real rest: it helps you stay upright during the day so you can save genuine sleep for nighttime.

7. Keep Your Sleeping Space Comfortable

A comfortable sleep environment makes it far easier to fall, and stay, asleep in an unfamiliar place. Start with where you're staying. If you're booking a hotel, be mindful about the one you choose: look for reviews that mention quiet rooms, blackout curtains, and comfortable beds, and consider requesting a room away from elevators, ice machines, and street-facing windows.

If you're staying with family or friends, make sure ahead of time that you'll have a good place to crash, ideally a private room with a real bed rather than a fold-out couch in a high-traffic living area.

Once you've settled in, a few small adjustments go a long way:

• Set the temperature. Check the thermostat so your room stays comfortably cool overnight.
• Silence interruptions. Make sure phones or clocks won't ring or beep while you sleep.
• Pack sound comfort. If you sleep with a white noise machine or fan, bring a portable version.
• Bring familiar items. A favorite throw blanket or a familiar scented lotion can help you drift off.

Accessories like a sleep mask, earplugs, and comfortable sleepwear also reduce disruptions and help your body settle into rest.

8. Try Melatonin

Melatonin is a hormone your body naturally produces to signal that it's time to sleep, and it's widely available over the counter. Alongside timed light exposure, it's one of the most effective tools for shifting your circadian rhythm to a new time zone.

Take 0.5 to 5 mg about 30 minutes before your target bedtime at your destination, and keep taking it for the first few nights until your sleep settles. Flying west and waking at 3 a.m.? A small dose in the early morning hours can help you sleep through until a reasonable time. Start with the lowest dose that works, since more isn't better.

Skip prescription sleeping pills for jet lag: they knock you out without actually resetting your body clock, and the side effects usually outweigh the benefits. If you're pregnant, taking other medications, or managing a chronic condition, run it by your doctor first.

The Takeaway

You can't fully recover from jet lag until your circadian rhythm catches up to your new time zone, but you're far from powerless. Prioritizing sleep, staying hydrated, using light strategically, eating light, and considering melatonin can all shorten the rough patch.

Because everyone's travel and health circumstances differ, consider consulting your doctor, a sleep specialist, or a travel clinic for advice tailored to your trip. With a little planning, you'll be enjoying your destination sooner.
