Short answer: the fastest way to beat jet lag is to live on local time from the moment you land. Get outside in daylight, stay out as late as you can, skip the afternoon nap, and go to bed at a normal local bedtime. Most people adjust at a rate of roughly one day per time zone crossed, and flying east is usually harder than flying west.
Jet lag is your body’s way of saying “excuse me, it’s 3am at home.” You can’t skip it completely, but you can make it a lot shorter. Here’s what actually helps before, during and after the flight, plus what changes when you travel with kids.
What jet lag is (and why east is harder)
Your body runs on an internal clock that uses daylight to decide when you feel awake, hungry and sleepy. When you cross several time zones quickly, that clock is still set to home. You feel tired at lunchtime, wide awake at 3am, and hungry at odd hours until it catches up.
Flying east (for example from the US to Europe) means you have to fall asleep earlier than your body wants, which most people find harder. Flying west means staying up later, which is easier to push through.
| Direction | What it feels like | What helps most |
|---|---|---|
| Flying east | Can’t fall asleep at night, hard to wake up in the morning | Morning daylight, an early (but not too early) bedtime, no sleeping in |
| Flying west | Sleepy in the late afternoon, awake very early | Late-afternoon and evening daylight, stay up until local bedtime |
Our rule: stay out of the hotel room
This is the one habit that makes the biggest difference for us. On arrival day, we drop the bags and get straight back out. We stay out of the room for as long as we can and really try not to nap, even when everyone is tired. A walk, an early dinner, a playground, anything that keeps you outside and moving. The bed is the enemy until it’s dark outside.
It’s hard for one day, but it’s much easier than spending the whole trip awake at 3am.
Before you fly
- Shift your sleep a little. For two or three nights before you leave, go to bed and get up a bit earlier (flying east) or later (flying west). With young kids, shift by about half an hour a night rather than a full hour.
- Don’t start the trip exhausted. Packing until 2am the night before makes everything worse. Get a decent night’s sleep before you go.
- Pick your flight with jet lag in mind. When you can, choose a flight that lands in the morning or early afternoon, so you have a full day of daylight to reset.
On the plane
- Switch your watch to destination time when you board, and start eating and sleeping on that schedule.
- Sleep if it’s night where you’re going. An eye mask, earplugs and a neck pillow help. Some travelers like sleep travel kits or noise-canceling headphones.
- Drink water, go easy on alcohol and caffeine. Cabin air is very dry, and both alcohol and caffeine make sleep worse.
- Eat light and move around. Walk the aisle every couple of hours on long flights.
After you land
- Get daylight. Light is the strongest signal your body clock has. Morning light helps after flying east, late-afternoon light after flying west.
- Eat on local time. Have meals at normal local hours, even if you’re not very hungry.
- If you really must nap, keep it short. Set an alarm for 20-30 minutes and nap before mid-afternoon.
- Plan an easy first day. Keep the important things (meetings, big sightseeing days, long drives) for day two or three when you can.
- Ask a doctor about melatonin. Some people find it helps with timing, but ask a doctor or pharmacist first, and always before giving it to children.
Jet lag with kids
Kids often adjust faster than adults, but the first couple of nights can be rough. A few things that help:
- Keep them outside and busy on day one. Parks, beaches and walks are better than museums when everyone is fading.
- Expect a 3am wake-up or two. Keep the lights low, offer a quiet snack, and avoid screens so it doesn’t turn into “morning”.
- Bring their bedtime routine with you. The same book, toy or bedtime order tells their body it’s night, wherever you are.
- Short car-seat or stroller naps are fine if a toddler simply can’t make it. Wake them gently after a short sleep.

Choosing a hotel that helps you recover
When you’re fighting jet lag, the room matters more than usual. A few things worth checking before you book:
- Blackout curtains and a quiet room. Ask for a room away from the elevator, the bar and the street.
- Early check-in. If you land in the morning, ask the hotel whether early check-in is possible, or at least whether you can leave your bags and shower.
- Breakfast times. A hotel that serves breakfast from 6:30am is a gift when everyone is up at 5.
- Room size for families. Separate sleeping areas mean one person’s 3am wake-up doesn’t wake everyone.
- Location. Being close to a park or a walkable area makes “stay outside all day” much easier.
Once you’ve found the right hotel, check that you’re not paying more than you need to. That’s why we built Hotel Ninja, a free Chrome extension for desktop that shows what the same room costs on Booking.com, Expedia, Hotels.com, Agoda and other supported sites, with taxes and fees included, while you browse. If you filter for free cancellation or a meal plan, like breakfast included, on the booking site, it compares only those rates.
Frequently asked questions
How long does jet lag last?
As a rough guide, about one day for every time zone you cross, though many people feel mostly normal after two to four days. Flying east usually takes longer to recover from than flying west.
Should I nap when I arrive?
Try not to. A long nap on arrival day makes it harder to sleep at night and slows down your adjustment. If you can’t stay awake, keep it to 20-30 minutes and before mid-afternoon.
What is the fastest way to get over jet lag?
Switch to local time straight away: get daylight, stay outside and active until the evening, eat at local mealtimes and go to bed at a normal local bedtime.
Do kids get jet lag?
Yes, but they often adjust faster than adults. Keep them outside and active on the first day, keep night wake-ups quiet and dark, and stick to their usual bedtime routine.
