Frequently asked questions

What Jet Lag Is

Your body has an internal clock that tells you when to sleep and wake. Fast travel across time zones puts that clock out of step with local time.

The Centers for Disease Control and Prevention calls this jet lag disorder. It becomes a concern when you cross at least two time zones.

Common symptoms

Trouble falling asleep or waking too early
Feeling sleepy during the day
Poor focus and slower thinking
A general unwell feeling
Upset stomach or changes in appetite

Symptoms usually start within one or two days of travel. They fade as your body clock catches up.

Why Flying East Is Harder

Your natural body clock runs a little longer than 24 hours. That makes it easier to stay up later than to go to bed earlier.

Flying west asks you to stay up later, which feels more natural. Flying east asks you to sleep earlier, which is harder.

After flying west, people adjust about 1.5 hours a day, says the disease agency. After flying east, it is about 1 hour a day. The American Academy of Sleep Medicine gives a simple rule of about one day per time zone.

Trip direction	Typical adjustment	Main goal
Westward	About 1.5 hours per day	Stay up later and get evening light
Eastward	About 1 hour per day	Sleep earlier and get morning light

Before You Fly

Shift your sleep schedule

For two or three days before the trip, move your bedtime by about one hour each day. Go earlier for eastward trips and later for westward trips.

Plan your light

Light is the strongest signal for your body clock. The American Academy of Sleep Medicine suggests using bright morning light before traveling east, in its jet lag guide.

Arrive rested

Get plenty of sleep in the days before you leave. Starting tired makes jet lag feel worse.

Choose your flight wisely

If you can, pick a flight that lands in the afternoon or early evening. You can then stay up until a normal local bedtime.

Quick tip. Set your watch and phone to destination time when you board. It helps you think and plan in local time.

On the Plane

Drink water often, because cabin air is very dry.
Limit alcohol, which can disrupt sleep.
Go easy on caffeine, especially late in the flight.
Sleep if it is night at your destination, and stay awake if it is day.
Use an eye mask, earplugs or noise-canceling headphones to rest.
Stand, stretch and walk the aisle when it is safe.

After You Land

Get daylight at the right time

After flying east, try to get bright morning light and avoid very bright light late in the day. After flying west, get light in the late afternoon and evening.

A walk outside is one of the best things you can do. Daylight is much brighter than indoor light, even on cloudy winter days.

Live on local time

Eat meals and go to bed at normal local times. Try to stay awake until a reasonable local bedtime.

Keep naps short

If you must nap, keep it to about 20 to 30 minutes, as the disease agency advises. Longer naps can ruin your night sleep.

Time your caffeine

Coffee can help you stay alert during the day. Stop about six hours before bedtime so it does not keep you awake.

Good to know. Light at the wrong time can make jet lag worse. That is why timing matters more than simply being outside.

Melatonin and Sleep Aids

Melatonin is a hormone that helps signal night to your body. Some travelers use melatonin supplements to adjust faster.

Timing matters a lot. The disease agency notes that melatonin taken at the wrong time can make the problem worse.

The Food and Drug Administration cannot approve supplements for safety or effectiveness before they go on sale. The agency explains this in its questions and answers on dietary supplements.

Talk with a doctor or pharmacist before you try melatonin or any sleep medicine. This is important if you are pregnant, take other medicines or have a health condition.

What About Short Trips?

For trips of about two days or less, the disease agency suggests keeping your home schedule. Your body will not have time to adjust anyway.

Plan important meetings for times when you would normally be alert at home. Then you can head back without fighting your body clock twice.

Food and Meals

Eat your meals at local times as soon as you arrive. Regular mealtimes give your body another clue about the new schedule.

Keep meals light on the flight and the first evening. Heavy, rich food late at night can make sleep harder.

Carry healthy snacks so you are not stuck with sugary airport food. Fruit, nuts and whole grain crackers travel well.

Tips for Business Travelers

Frequent travelers feel jet lag the most, so planning matters. The disease agency says a clear sleep and light plan helps the most.

Book meetings for times when you will feel sharp. Avoid big decisions on the first day if you can.

If you cross many time zones often, ask your doctor for a personal plan. They can suggest safe options for your health and schedule.

When to See a Doctor

Jet lag usually fades on its own within days. See a doctor if sleep problems last long after you return home.

Also get help if you feel very unwell or have trouble breathing. Leg pain and swelling after a long flight can signal other problems too.

Jet Lag and Kids

Children feel jet lag too. Keep their routines simple and get them outside in daylight after you arrive.

Bring familiar items like a favorite blanket for bedtime. Be patient for the first few nights while everyone adjusts.

Shift their bedtime a little before the trip too, if their school schedule allows it.

Make Your Hotel Room Sleep Friendly

Your room can help or hurt your recovery. Close the curtains fully at night and keep the room cool.

Turn off bright screens an hour before bed. Use white noise or earplugs if the street is loud.

Plan Your First Day Abroad

Keep your first day light. Schedule a walk, an easy meal and an early night instead of a packed tour. Save the big sights for day two or three.
