Can't Sleep While Traveling? Causes and What Helps
Can't sleep while traveling? Learn why the first night effect, jet lag and hotel rooms keep you awake, how to prepare before your flight, and what helps
You booked a comfortable hotel, arrived worn out after a long trip, then spent the night tossing and turning. If you can't sleep while traveling, there are usually three reasons: your brain stays on guard in a new place, a time difference confuses your body clock, and travel stress does the rest.
The good news is that you can prepare for most of these before you pack.
Why can't I sleep while traveling?
Sleep depends on cues your body knows well: your bed, your room, your usual bedtime and the light you see every morning. When you travel, all of these change at once.
When people can't sleep while traveling, one of two things is usually at work, and often both:
Travel fatigue: general tiredness from the journey, waiting around and poor sleep before the trip. It affects any traveler, even without a time change.
Jet lag: it happens when you cross two or more time zones. Your body clock stays on home time while you live on another.
The difference matters. Travel fatigue usually clears after a night or two of good sleep, while jet lag takes days for the body clock to adjust.
You travel often and your sleep never settles?
If you can't sleep while traveling on every trip, or the problem continues after you get home, there may be a cause worth assessing. You can see a sleep doctor from anywhere, without waiting until you are back.

Common causes of travel insomnia
When you can't sleep while traveling, several causes often come together on the same trip:
The first night effect
This one surprises many people. In a Brown University study of 35 volunteers, part of the left side of the brain stayed more active during deep sleep on the first night in a new place, like a night watchman. It also reacted faster to sounds, so sleepers woke more easily.
By the second night the difference had largely disappeared. That is why so many people can't sleep while traveling on their first night in a hotel, even in a comfortable room.
The hotel room
A noisy air conditioner, curtains that let light in, a corridor with guests passing, and a pillow that feels nothing like yours. Small details, but enough to break up your sleep. For many people who can't sleep while traveling, the room itself is the main problem.
Travel anxiety and a changed routine
Worry about missing the flight, thinking about tomorrow's meeting or plans, and an alarm at an unusual hour all keep the mind alert the night before travel and after.
Caffeine and alcohol on the way
Airport coffee keeps you alert, but caffeine lasts for hours and can delay sleep when you arrive. Alcohol may help you drift off, but it makes sleep more broken later in the night.
Sleeping on a plane or in a car
Sitting upright, noise and lack of space make sleep on the way light and broken, so you arrive with a sleep debt that makes the first days harder.
Jet lag and time zones
When you cross two or more time zones, your body clock stays on home time for days. You feel sleepy at midday and wake in the middle of the night wide awake.
Common symptoms include:
Trouble falling asleep at night, or waking very early
Daytime sleepiness and fatigue
Poor concentration
Upset stomach and changes in appetite
Mood changes
According to Mayo Clinic, symptoms usually appear within a day or two of crossing at least two time zones, and recovery takes about one day for each time zone crossed. So the bigger the time difference, the more likely you can't sleep while traveling.

Is flying east harder than flying west?
Usually, yes. In most people the body clock runs slightly longer than 24 hours, so delaying sleep is easier than bringing it forward. According to the US Centers for Disease Control and Prevention, the body adjusts by about 1.5 hours a day after flying west and about 1 hour a day after flying east.
Examples from Riyadh:
Riyadh to London: west, with a 2 to 3 hour difference. Adjusting is relatively easy.
Riyadh to Kuala Lumpur: east, with a 5 hour difference. You need to sleep earlier than usual, which is harder.
Riyadh to New York: west, with a 7 to 8 hour difference. You may wake before dawn for the first few days.
How to prepare your sleep before you travel
Much of why you can't sleep while traveling can be eased days before the flight:
Shift your bedtime by about an hour a day for two to three days before you leave: earlier if you are flying east, later if you are flying west.
Sleep well on the nights before travel, and don't stay up packing the night before your flight.
Choose a flight that lands close to evening if you can.
Pack a small sleep kit: an eye mask, earplugs and a neck pillow.
If you use a CPAP machine, make sure it comes with you.
If you need a detailed step-by-step plan for changing your sleep times, you will find it in our sleep adjustment schedule.
How to sleep on a plane
Sleep on a plane is never perfect, but these steps may help if you can't sleep while traveling by air:
Set your watch to destination time as soon as you board, and sleep if it is night there
Pick a window seat so you can rest your head and avoid passengers moving past
Use an eye mask and earplugs or noise-cancelling headphones
Avoid coffee and tea in the hours before you want to sleep
Drink water regularly, as dry cabin air adds to fatigue
Wear comfortable clothes in layers you can add or remove
What to do after you arrive
The first few days matter most if you can't sleep while traveling:
Use light to your advantage
Light is the strongest signal for your body clock. Morning light brings your sleep time forward, and evening light pushes it later. After flying east, get outside in the morning sun. After flying west, make the most of late-afternoon light.
Live on local time straight away
Eat, sleep and wake on local time from day one, even if you feel tired.
Keep naps short
If you can't fight the sleepiness, keep naps under 30 minutes and early in the day so they don't steal from your night.
Watch your caffeine timing
Coffee in the morning may help you stay alert, but avoid it in the afternoon so it doesn't delay your sleep.
Set up the hotel room
Ask for a room away from the lift, set the air conditioning to comfortably cool, and close the curtains fully.
Melatonin and sleeping pills when traveling
Some travelers who can't sleep while traveling turn to melatonin, the hormone the body releases as darkness falls. A Cochrane review suggests it may help on flights crossing five or more time zones, especially eastward, and the CDC notes that a small dose is often enough. However, the NHS does not recommend it for jet lag because the evidence is not strong enough. Timing matters more than dose, so don't use it without medical advice.
As for sleeping pills, a doctor may prescribe one for a few nights in specific cases. But never try a sleeping pill for the first time on a plane. It may cause dizziness or grogginess on arrival, and it carries more risk for people with sleep apnea. Read more about the risks of long-term use in our article on the harms of sleeping pills.
Sleep on Umrah and Hajj trips
Umrah and Hajj trips are different: overnight travel at times, crowds, and rituals performed late at night or before dawn. Many pilgrims can't sleep while traveling, and sleep loss builds up quickly, especially in older pilgrims.
Tips that may help:
Sleep well in the days before the trip, and don't start the journey exhausted
Split your sleep into two fixed blocks if you cannot sleep through the night
Take an eye mask and earplugs, as accommodation can be crowded
Drink water regularly, especially in the heat
Don't drive between cities when you feel drowsy, and stop to rest at the first sign of tiredness
Sleep apnea and travel
If you have sleep apnea, leaving your machine at home can make nights away worse and increase daytime sleepiness. On the other hand, if you can't sleep while traveling and also snore loudly or wake up choking, it may be a sign of sleep apnea that has not been diagnosed yet.
Tips for CPAP users:
Carry the machine in your hand luggage as a medical device, never in checked baggage
Contact your airline before travel if you want to use it during the flight
Take a plug adapter that fits the sockets at your destination
Bring a copy of your doctor's report
Snoring on a trip, and your roommate noticed?
If a travel companion notices loud snoring or pauses in your breathing, don't ignore it. A home sleep apnea test checks your breathing in your own bed.
💬 Ask about the test on WhatsApp
Pilots, cabin crew and business travelers
Mayo Clinic notes that pilots, flight attendants and business travelers are among the groups most likely to get jet lag, because they cross time zones constantly and rarely give their bodies time to adjust.
For these groups, travel insomnia is not a one-trip problem but a recurring one that affects focus, decision-making and safety. That is why airlines and transport companies take their employees' sleep seriously and sometimes need dedicated assessment programs.
Children and older adults on the road
Children and older adults are more likely to find they can't sleep while traveling, because the first night effect is stronger in children, teenagers and older adults. Older adults also usually take longer to recover from jet lag.
For children: keep the same bedtime routine, such as a story or a favorite toy, and shift their times gradually.
For older adults: plan rest days after arrival, and make sure they take their medicines on time in the new time zone after checking with their doctor.
When should you see a doctor?
Travel insomnia usually clears within days. An assessment is advisable if:
You feel very sleepy or doze off while driving after travel
Insomnia lasts more than two weeks after you return
You can't sleep while traveling on every trip, and it affects your work
A roommate notices loud snoring or pauses in your breathing
You already struggle to sleep at home, and travel makes it worse
Insomnia still there after you get home?
Sometimes travel brings to light an insomnia that was already there. CBT-I sessions help you get your sleep back without relying on sleeping pills, and some sessions can be attended remotely.
💬 Ask about the sessions on WhatsApp
How to get your sleep back after you return
Coming home means a new disruption in the opposite direction. These steps help:
Go back to your usual bedtime and wake time from the first day.
Get morning light, especially after a trip west.
Avoid long naps, however tired you feel.
Keep your first two days back at work light if you can.
Don't drive long distances on the day you arrive if you feel sleepy.

Frequently asked questions
Does taking my own pillow help me sleep in a hotel?
It may. A familiar pillow gives your brain a signal of safety and comfort, and can reduce part of the new-place effect.
Should I stay awake until evening after I arrive?
Usually yes, if you land during the day. Staying awake until local bedtime, with a short nap if needed, helps your body clock adjust faster.
Are short trips without a time difference any different?
Yes. Jet lag does not happen, but the first night effect and travel fatigue can still cause a night or two of light sleep.
Does fasting while traveling affect sleep?
It may, because the times of suhoor and iftar shift with the new time zone. Keeping a fixed bedtime and wake time on local time helps reduce the effect.
