Knowing how to get over jet lag can make your next long-haul flight much more comfortable. When you arrive at your destination feeling tired, unable to sleep at night, or drowsy during the day, the first few days of your trip can be difficult.
These symptoms are typical of jet lag, which is a temporary disturbance of your body’s internal clock that happens when you cross several time zones in a short period of time.
If you want to recover faster, the key is to help your body gradually adapt to the local time at your destination. Good sleep routines, proper timing of daylight, regular feeding, drinking fluids and careful management of caffeine can help make the transition easier.
But not all travellers require the same recovery plan. A person who crosses two time zones might need only slight changes, whereas a person who crosses eight or ten time zones might need more significant disruption.
This guide from World Flight Vibes explains how to create a practical, day-by-day jet lag recovery plan based on the number of time zones crossed, the direction of travel, and your individual sleep needs.
These tips can help you adjust to a new time zone and make your trip as smooth as possible, whether you’re travelling for business, a long-awaited holiday or returning home after an international trip.
What Is Jet Lag and Why Does It Happen?
Jet lag is the disruption of your body’s internal clock, or circadian rhythm, from the time in your destination country.
Your internal clock plays a role in determining your sleepiness and wakefulness. It also affects body temperature, hormone production, appetite and other functions that have a roughly 24-hour rhythm.
The internal clock is especially sensitive to light and darkness. Traveling across multiple time zones can throw off your body clock and the local day-night cycle.
For instance, you might be in a place where it is day time, but your body is still expecting night time. You may feel tired in the afternoon or awake at three in the morning.
Common Symptoms of Jet Lag
Jet lag can impact travellers in various ways, but typical symptoms include:
- Difficulty falling asleep at the destination’s bedtime.
- Waking up too early or repeatedly during the night.
- Daytime fatigue and reduced alertness.
- Difficulty concentrating or remembering information.
- Irritability and changes in mood.
- Changes in appetite or digestive discomfort.
Jet lag is not just a normal fatigue from traveling. Long flights can cause fatigue due to lack of sleep, sitting for extended periods and the stress of travel. The other problem with jet lag is that your internal clock is out of sync with the local day-night cycle.
The NHS guide to jet lag says symptoms usually get better in a few days as your body gets used to the new time zone.
How Many Time Zones Have You Crossed?
You can use the number of time zones crossed to make an estimate of how much adjustment you might need. But it does not specify the exact duration of recovery.
These are the categories to use as a practical guide when planning your trip.
| Time zones crossed | Possible experience | Suggested approach |
| 1–3 | Mild sleep disruption for many travellers | Maintain a consistent local routine |
| 4–6 | More noticeable changes in sleep and energy | Plan sleep timing and daylight exposure carefully |
| 7–9 | Greater circadian disruption may occur | Follow a structured recovery schedule |
| 10–12+ | A substantial adjustment may be necessary | Allow extra recovery time and consider personalised guidance |
These categories are planning guides and not medical thresholds. The way you sleep, the direction you travel, when you arrive and how well you sleep can all affect your mood.
Why Travel Direction Matters
When traveling eastward, your body clock tends to be set earlier, and when traveling westward, it tends to be set later.
The forward shift of the body clock is more difficult for many people and makes eastbound travel more challenging.
For instance, a flight from London to Tokyo typically involves an earlier bedtime. A flight from London to New York typically takes a later flight. The exact time difference depends on the change in daylight saving time.
A helpful recovery plan is thus one that takes into account the number of time zones traversed and the direction of travel.
How to Get Over Jet Lag: Start Before Your Flight
You don’t need to start your recovery on the ground. Planning your sleep routine before you leave can help minimise the adjustment period upon arrival.
1. Gradually Adjust Your Bedtime
If you are heading east, attempt to shift your bedtime and morning routine earlier by two or three days prior to your trip.
For westbound journeys, gradually move them later instead. For instance, if you usually go to bed at 11 p.m. and you are heading east, you could try going to bed 30 minutes earlier each day.
Adjust slowly and don’t deprive yourself of sleep to get your body on a new schedule. It is important to get adequate rest prior to a long-haul flight.
2. Check Your Destination’s Local Time
Before you get on the plane, find out what time it is at your destination and use that to plan your sleep and activity schedule for the flight.
Changing your phone or watch to the destination’s time zone can make the transition easier. Begin thinking about when you will sleep, eat, and get daylight after landing.
This easy recipe can save you from making all your decisions based on home time.
3. Prioritise Sleep Before Departure
Avoid starting your trip already sleep deprived.
Pack your bags ahead of time, leave plenty of time to get to the airport, and go to bed at the same time each night for the few days leading up to your trip.
You might also want to bring a sleep mask, earplugs, and a comfortable travel pillow to help you sleep on the plane.
In-Flight Jet Lag Strategy: Follow the Destination-Time Rule
A good way to get ready for arrival is to plan your flight schedule according to the local time of the destination.
This is not about making yourself go to sleep when you are not sleepy. Rather, rely on the local clock to determine when to sleep and when to stay awake, as long as it is comfortable and safe for you.
If It Is Nighttime at Your Destination
Try to rest during the flight.
- Use an eye mask and earplugs to reduce light and noise.
- Reduce screen brightness and other stimulation.
- Wear comfortable clothing.
- Avoid excessive caffeine and alcohol.
- Allow yourself time to relax even if you cannot fall asleep immediately.
If It Is Daytime at Your Destination
If you feel well enough, try to stay awake.
Reading, watching a film, or getting up to stretch and walk around the cabin when permitted can help you stay active.
If you are very sleep deprived, you don’t have to try to stay awake. Adequate rest and safety should always take priority.
Stay Hydrated During the Flight
Drink water frequently during the trip, especially if you are thirsty or have dry eyes and mouth.
Low humidity in aircraft cabins can cause discomfort. There is no universal requirement, however, to drink a certain amount of water per hour of flight time.
The amount of fluid you need is based on your body, activity, health and medical advice. Don’t use alcohol as a sleep aid as it can interfere with sleep.
For more official travel-health advice, see the UK Civil Aviation Authority’s guidance on air travel and your health.
Jet Lag Recovery Plan by Number of Time Zones Crossed
The following day-by-day plans offer a practical structure for your first few days after you arrive.
They do not provide recovery time guarantees. Follow the routine as long as necessary and modify it according to your destination, sleep needs, and travel schedule.
Plan A: Crossing 1–3 Time Zones
For many travellers, a one to three hour difference may be relatively manageable. But if you’re already fatigued or have an early start in the works, even a slight adjustment can make a difference.
Arrival day: Establish local time
- Change your phone and watch to local time.
- Eat meals at reasonable local times.
- Spend some time outdoors during the destination’s daytime.
- Aim for a reasonable local bedtime.
- Avoid long daytime naps that could interfere with nighttime sleep.
Day 1: Maintain a consistent routine
Get up at a normal local time, regardless of whether your sleep was good or bad.
Have breakfast, get some daylight, and limit caffeine to the morning. If you are feeling sleepy, a brief nap of 15-20 minutes can help you feel more awake without significantly disrupting your night’s sleep.
Day 2: Continue the adjustment
Maintain your bedtime and wake-up time. Don’t make up for a bad night’s sleep by napping for a few hours during the day.
If the time difference is small, only minor adjustments are needed for many travellers.
Plan B: Crossing 4–6 Time Zones
When you cross four to six time zones, the mismatch between your internal clock and the destination’s schedule may be more noticeable.
May feel drowsy too early, may have difficulty waking up, or may have trouble sleeping at night.
Arrival day: Begin following the local schedule
The first thing you need to do is to begin to follow the clock of the destination.
- Eat according to local meal times.
- Get appropriately timed daylight.
- Stay awake until a reasonable local bedtime if you can do so safely.
- If you need a nap, keep it brief where practical.
- Prepare a dark, quiet, comfortable sleeping environment.
Day 1: Stabilise your sleep schedule
Set a realistic wake-up time and stick to it.
Eat breakfast, get dressed, and begin your day rather than remaining in bed for hours after waking. Gentle activity, such as walking, may help you feel more alert.
Avoid caffeine late in the day, especially if you are having difficulty falling asleep.
Day 2: Support your body clock
Continue your local routine. Eat at regular times, get the right amount of daylight and night time sleep.
If you still feel tired, cut back on unnecessary demands instead of forcing yourself through an exhausting schedule.
Day 3: Review your progress
See if your sleep and energy levels are improving.
It is possible to still wake up early or feel tired in the afternoon, but a consistent routine can help with the adjustment.
Do not assume that you are completely recovered at this stage if symptoms persist.
Plan C: Crossing 7–9 Time Zones
A seven to nine hour time difference can create a significant mismatch between your internal clock and the day/night cycle at your destination.
This level of change can make it difficult to manage the first few days, but a structured plan can help.
Arrival day: Keep your schedule manageable
- Follow local time for meals and bedtime.
- Get daylight at a suitable time for your travel direction.
- Avoid overloading your itinerary with demanding activities.
- Use short naps if necessary rather than routinely sleeping for several hours during the day.
- Avoid driving if you are too tired to do so safely.
Day 1: Focus on consistency
Get up at a reasonable local time and set up a simple morning routine.
If you can, eat breakfast, dress up and take a walk. Schedule activities to fit your energy level and don’t make important decisions when you are very sleep deprived.
Day 2: Manage light and darkness
Daylight is one of the most powerful cues for resetting your body clock, but it has to be at the right time.
Light in the morning can help the body clock move earlier, and light in the evening can help the body clock move later. The optimal timing will vary based on the direction of travel and one’s internal circadian timing after a significant time-zone change.
Don’t think that more sun at any time of day will always help. For a very specific plan, see a health care provider.
Day 3: Keep your routine steady
Maintain local time for waking, feeding, and sleeping.
These can be positive signs that you are adjusting if you feel more awake during the day and sleep for longer periods at night.
Days 4–5: Allow more time if needed
Continue your routine and track your progress.
Your energy might improve before your sleep is fully normal, or your sleep might improve before daytime tiredness goes away.
Don’t rely on a set number of days to determine when you’re “supposed” to be recovered.
Plan D: Crossing 10–12 or More Time Zones
The transition can be especially difficult when crossing about half the globe. Your body may initially interpret the local day as night and vice versa.
Given the significant time difference, pay attention to the local time in the destination, the direction of travel, and the proper timing of light exposure.
Arrival day: Make the first adjustment
Begin adapting to local time by planning meals and activities around your destination’s schedule.
For morning arrivals, start the local day if you feel alert enough. Evening arrivals call for a calmer approach, with bedtime set to a reasonable local hour.
When fatigue becomes overwhelming, prioritise rest and safety. Where possible, keep daytime naps short to avoid disrupting nighttime sleep.
Day 1: Create a predictable routine
Establish a regular wake-up time, eat meals at local times, and incorporate gentle activity.
Don’t expect a reset right away. Even if you are on a sensible plan, you can still feel sleepy at odd times.
Day 2: Be deliberate about light
Take advantage of the light and dark as a recovery strategy.
The time difference is significant and can cause a delay in adjustment if the light is not timed correctly. Consider a personalised light-exposure schedule if you are crossing many time zones or need to perform at a high level immediately after arrival.
Day 3: Prioritise sleep quality
Maintain a dark, quiet bedroom, limit bright light near bedtime, and avoid late caffeine.
Allow yourself sufficient time to sleep. If you have important appointments, schedule breaks and do not perform safety-related tasks when you are very sleepy.
Days 4–7: Continue adapting
Follow your local routine for the first week.
Observe if nighttime sleep is becoming more regular and if daytime sleepiness is decreasing.
If there is a significant time difference, it may take more than a week to resolve completely. If symptoms are severe, persistent or unusual, seek medical advice.
Eastbound vs. Westbound Travel: Which Is Harder?
The direction of travel affects the direction of your body clock’s adjustment.
Travelling East: Move Your Schedule Earlier
When you travel east, local time moves ahead of your home time. You may need to fall asleep and wake up earlier than your body expects.
Helpful strategies include:
- Gradually moving bedtime earlier before departure.
- Maintaining a consistent local wake-up time after arrival.
- Getting appropriately timed daylight.
- Avoiding light exposure at times that could shift your body clock in the wrong direction.
Eastbound adjustment can be more challenging as it is difficult to move the body clock forward.
Travelling West: Move Your Schedule Later
As you head west, local time falls behind home time. It may be necessary to go to bed later and get up later.
Helpful strategies include:
- Gradually moving bedtime later before departure.
- Staying awake until a reasonable local bedtime after arrival.
- Getting appropriately timed afternoon or evening light when suitable.
- Avoiding excessive daytime sleeping that makes it harder to sleep at the destination’s nighttime.
These are general guidelines, not universal light-exposure rules. The best time varies depending on the number of time zones crossed.
Please refer to the UK Civil Aviation Authority’s air travel health guidance for further information.
How to Build a Practical Jet Lag Schedule
A useful jet lag schedule does not need to be complicated.
Begin with four anchors: getting up, getting the right amount of daylight, eating meals, and going to bed.
The following is an example of how you could plan a day after you arrive.
| Local time | Suggested activity | Purpose |
| 7:00–8:00 a.m. | Wake up and eat breakfast | Establishes a consistent start to the day |
| Morning | Get appropriately timed daylight | Supports circadian adjustment |
| 12:00–1:00 p.m. | Eat lunch | Encourages a predictable daily routine |
| Early afternoon | Take a short nap if necessary | May improve alertness |
| Afternoon | Walk or do gentle activity | Helps you remain active during the local day |
| Evening | Eat dinner and reduce stimulation | Supports a calmer evening |
| Before bed | Dim lights and prepare for sleep | Helps create a consistent wind-down routine |
| Local bedtime | Go to bed at a reasonable time | Supports the destination’s sleep schedule |
These times are indicative only and not a universal prescription.
Adjust the routine according to your arrival time, work commitments, destination, and personal sleep needs. The optimum timing of daylight may vary from the example after crossing many time zones.
The idea is to create a routine that is sustainable and helps your body adjust, rather than trying to change your body clock overnight.
How to Use Sunlight to Cure Jet Lag Fast
Natural light plays a major role in regulating your circadian rhythm. If used at the appropriate time, it can assist your internal clock in shifting towards the destination’s schedule.
But it’s not about spending as much time in the sun as possible, it’s about the timing.
During local daytime, normal outdoor activities may be sufficient for adjustment for a short period of time. For larger differences, light exposure may need to be timed more carefully.
Consider these principles:
- Morning light: Often encourages an earlier body-clock shift when the timing is appropriate.
- Evening light: Often encourages a later body-clock shift when the timing is appropriate.
- Darkness at bedtime: A dark room can help support sleep during the destination’s nighttime.
- Reduced bright light before bed: Dimming lights and limiting stimulating screen use can help you wind down.
After long-haul flights, don’t always assume that early morning sun is the best option.
If you are crossing many time zones, seek individualised advice on when to seek or avoid bright light. A light routine that is not timed correctly can actually hinder the adjustment you are trying to make.
Temperature and Sleep: Try a Warm Shower Before Bed
A comfortable sleep environment can help you sleep while your body is adjusting to a new time zone.
Core body temperature fluctuates throughout the day and tends to drop as sleep time nears. This change is associated with the normal transition towards sleep.
Taking a warm shower or bath approximately 60–90 minutes before bedtime may help you relax and fall asleep more comfortably. Your body cools off after a bath, and this can help your core temperature drop as it should during sleep.
Create a Comfortable Sleeping Environment
In the first few nights after you arrive:
- Take a comfortably warm shower if it helps you relax.
- Keep your bedroom dark, quiet, and comfortably cool.
- Reduce bright light and stimulating activities as bedtime approaches.
- Maintain a consistent bedtime based on local time.
A warm shower is a comfort measure, not a guaranteed jet lag treatment. It won’t reset your body clock, and the right timing of daylight is still crucial.
Hydration, Food, and Exercise During Jet Lag Recovery
Sleep is just one component of recovery. How you feel can also be affected by what you eat, drink, and do throughout the day.
Drink Water Regularly
Stay hydrated during and after your flight.
Water helps with overall health, but it won’t reset your body clock. Adhere to any fluid restrictions prescribed by your health care provider.
Don’t use alcohol to sleep as it can affect sleep.
Eat According to Local Time
Try to have meals at reasonable times in your destination’s schedule.
Smaller, lighter meals may be easier if you are feeling nauseated or have a decreased appetite.
You don’t have to go on a special diet or try to eat a lot at one time to reset your internal clock.
Move Throughout the Day
When it is safe to do so, stretch and walk around the aircraft.
Once you arrive, walking can help you feel more alert and get you out of the rut of sitting for long periods.
Don’t push yourself too hard when you are very tired. Rest and a gradual return to normal activity should be your first priority.
Set a Caffeine Cut-Off Time
Caffeine can help to make you feel more alert, but if you drink it too near bedtime, it can make it more difficult to fall asleep.
One good first step is to eliminate caffeine at least 8 hours before your local bedtime. For those who are especially sensitive to caffeine or have trouble sleeping, try a longer period, such as 10 hours.
If you are going to bed at 10 p.m., for instance, you should have your last cup of coffee by 2 p.m. (eight hours before bedtime) or by noon (ten hours before bedtime).
Remember that caffeine is found in more than coffee. It can also be found in tea, energy drinks, cola and some other products.
The exact cut-off will vary based on your sensitivity and consumption habits. Use this as a guideline, not a rule.
Can Melatonin Help You Get Over Jet Lag?
Melatonin is a hormone involved in regulating the body’s sleep-wake cycle. Melatonin products are occasionally used to assist with sleep timing, but not for everyone.
They can have different effects depending on the time of day, dose, other medications, and personal health conditions.
Melatonin tablets are not generally recommended for jet lag by the NHS as they believe there is not enough evidence to support their use for this purpose.
If you are thinking about taking melatonin, consult a pharmacist or physician, especially if you are taking other medications, have a medical condition, or need to be awake for work or driving.
Don’t expect melatonin to shift your body clock at any bedtime.
Sleeping tablets should also not be used as a casual way of trying to impose a new sleep pattern. They may have side effects and make you sleepy the next day, and some are addictive.
Read the NHS advice on jet lag for official guidance in the UK.
Returning Home: Plan for Re-Entry Jet Lag
When your holiday or business trip is over, jet lag recovery isn’t necessarily over, too.
The trip back home may also interfere with your sleep, especially if you have to get back to work, school, or other demanding activities.
Build a Recovery Buffer When Possible
If possible, try to take a break of about 24-48 hours between coming home and returning to challenging work or high-stakes engagements.
This is a planning suggestion and not a guaranteed recovery period.
During this time:
- Return to your normal local sleep and wake-up schedule.
- Get appropriately timed daylight.
- Eat meals at your usual local times.
- Avoid long daytime naps that could interfere with nighttime sleep.
- Keep demanding activities manageable if you remain tired.
If you are unable to build in a buffer, prioritise sleep and minimise unnecessary demands in the first few days back.
Avoid Compounding Sleep Debt
If you are flying long-haul, you might be facing sleep loss and circadian disruption.
Avoid making up for it with too much caffeine, late work, or odd hours.
If you are very sleepy, do not drive or do tasks that require constant concentration. See a health care provider if sleep issues continue or significantly interfere with daily life.
The idea is to ease back into your normal life as much as possible, and not to expect your body to adjust to normal life right after you land.
Common Mistakes That Can Delay Jet Lag Recovery
Even a well-planned trip can become harder when you fall into habits that interfere with sleep.
Sleeping for Hours During the Day
A long daytime sleep may make it difficult to fall asleep at the local bedtime.
If you must nap, do so for a short period of time if possible. But don’t overlook extreme drowsiness when sleep is required for safety.
Drinking Alcohol to Fall Asleep
Although alcohol can make you feel sleepy, it can also affect the quality of your sleep. It is not a good remedy for jet lag.
Drinking Caffeine Too Late
Late-day caffeine can keep you awake at night. Use it strategically, not all day long.
Ignoring the Destination’s Local Time
If you are staying for a longer period of time, it may be difficult to get into a new routine if you continue to eat, sleep and plan all of your activities around your home time.
However, if the trip is very short, say 2-3 days, some home-time routines may be acceptable. The NHS recognises that some travellers may choose not to switch their schedules completely for short visits.
Using Light at the Wrong Time
Light is a powerful body-clock signal, but mistimed exposure may work against your intended adjustment. This is particularly important when traveling across multiple time zones.
Expecting an Instant Cure
There is no guaranteed way to cure jet lag fast. The aim is to alleviate symptoms and to help the person adjust slowly, not to remove all symptoms at once.
When Should You Seek Medical Advice?
Jet lag tends to get better as your body adapts, but not all symptoms following a flight are necessarily due to jet lag.
If your sleep issues continue, your symptoms are severe, or fatigue continues to interfere significantly with your daily activities, consider talking to a health care provider.
Get immediate medical attention for severe or unusual symptoms, such as chest pain, shortness of breath, fainting, or severe leg swelling or pain following a long flight.
If you are extremely drowsy, do not drive, ride a bike in traffic, use machinery, or do other tasks that require constant attention.
Frequently Asked Questions About Jet Lag Recovery
1. How to Get Over Jet Lag Quickly?
Follow the local schedule of your destination, get the right amount of daylight, take short naps, limit alcohol intake, drink water, and go to bed and get up at the same time.
These measures can help alleviate symptoms, but there is no instant cure.
2. How Long Does Jet Lag Last?
Jet lag usually gets better in a few days, but it can take longer for some people. The adjustment period may be longer with larger time differences, eastbound travel, disrupted sleep and individual circadian rhythms.
Read our related guide: How Long Does Jet Lag Last?.
3. Is Jet Lag Worse When Travelling East or West?
Many people find it harder to travel east because the body clock has to adjust earlier. But the severity of symptoms also depends on the number of time zones crossed, individual sleep patterns, and the timing of light exposure.
4. Should I Sleep When I Arrive at My Destination?
Aim to keep to the local day/night routine. If you arrive during the day, staying up until a reasonable local bedtime might help. If you are having trouble staying awake, a brief nap might be OK. Safety and adequate rest should always take priority.
5. Does Drinking Water Cure Jet Lag?
No, drinking water is not a stand alone solution for resetting the body’s circadian rhythm, but it does help with hydration and overall comfort. Timing of sleep and light exposure is also crucial.
6. Can I Prevent Jet Lag Completely?
Its impact can be minimised by planning ahead, getting plenty of rest, and making a gradual schedule change. But even with careful preparation, crossing multiple time zones can still mess with your body clock.
7. Is It Better to Stay Awake All Day After a Long Flight?
Not if you are dangerously tired. Being awake during the daytime of the destination may help you sleep at nighttime there, but if you are very sleepy, it may be unsafe to try to stay awake. Take short naps if necessary and do not engage in dangerous activities when tired.
8. Does a Jet Lag Schedule Work for Everyone?
While a general schedule can help you get into good habits, the ideal plan will depend on the direction of your travel, how many time zones you cross, when you arrive, and your typical sleep routine. If you are travelling across multiple time zones, you might want a more individualised plan.
9. Does a Warm Shower Help With Jet Lag?
Taking a warm shower before sleep can help you unwind and get ready for bed. But it doesn’t reset your body clock on its own. To adjust, use a comfortable bedtime routine, a consistent local sleep schedule, and the right timing of light exposure.
10. When Should I Stop Drinking Coffee After a Long-Haul Flight?
As a practical first step, steer clear of caffeine in the 8 hours leading up to your intended sleep time. If you are sensitive to caffeine or have trouble sleeping, a ten-hour cut-off might be more appropriate. Everyone reacts differently, so take what works for you.
