What is Jet Lag and Why Does It Happen?

Jet lag, or circadian rhythm disruption, happens when you cross multiple time zones and your body’s internal clock, known as the circadian rhythm, struggles to catch up to this new time zone.

This biological clock regulates not just sleep but also digestion, hormone levels, and overall energy cycles. When it gets thrown off balance, the body doesn’t know whether it should be awake, asleep, hungry, or even alert. That’s why people experience a wide range of symptoms beyond just feeling tired when they experience jet lag.

One of the biggest problems with jet lag is the sheer exhaustion that comes with it. Even if you’ve had a full night’s sleep, you might wake up feeling like you barely rested. Falling asleep at the right time becomes difficult, and even when you do manage to sleep, you may find yourself waking up at odd hours.

Your brain also doesn’t function at full capacity, and many travelers report feeling mentally sluggish, having trouble concentrating, or even struggling to remember basic things. For a lot of people, mood swings are common, ranging from irritability to mild anxiety or even a short-term feeling of depression.

And let’s not forget the physical effects, as many people experience stomach discomfort, bloating, nausea, or changes in appetite. These issues arise because your digestive system also operates on a circadian rhythm, and when your meal schedule changes abruptly, your body doesn’t know what to do with itself.

Jet lag is not a one-size-fits-all experience, though. Some people adjust quickly, while others take days to recover. Several factors influence the severity of jet lag, including the number of time zones crossed, as the more timezones you travel, the harder it is for your body to catch up.

The direction of travel also matters: heading eastward, where you “lose time,” tends to be much harder than traveling westward, where you gain extra hours. That’s because it is generally easier to extend the day rather than shorten it.

Your personal adaptation speed plays a role in all of this as well. Some people naturally adjust faster than others, based on lifestyle habits and genetics.

Exposure to natural light is also one of the biggest external influences on your body clock. If you get light at the wrong time, it can make jet lag worse rather than better.

Other factors include your overall health and age. Older adults and people with pre-existing sleep disorders may have a harder time bouncing back from jet lag.

The flight itself also plays a role, where longer flights with poor in-flight sleep tend to make symptoms worse. The pressurized cabin air and lower oxygen levels at altitude can leave you feeling more drained than you realise, especially when combined with dehydration.

Ultimately, jet lag is a battle between your internal body clock and the external world. Your goal should be to help your body adjust as smoothly as possible by gradually shifting your rhythms before and after you travel.

The good news is that with a structured approach, you can speed up the adjustment process significantly and make your transition into a new time zone far more manageable.

This is where the Jet Lage Prevention and Recovery Tool really shines.

How the Jet Lage Prevention and Recovery Tool Works

Using the Jet Lag Prevention and Recovery Tool is simple, but behind the scenes, it applies science-backed strategies to help your body transition as smoothly as possible.

Here’s how it works in detail:

1. Enter Your Trip Details: Start by selecting your departure and arrival time zones, travel dates, and flight times. This information is crucial because the difference in time zones will determine how your circadian rhythm needs to adjust. The tool takes into account whether you’re traveling eastward or westward, as each direction presents unique challenges when it comes to adapting to local time. 
2. Input Your Sleep Schedule: Your natural sleep-wake cycle plays a major role in how quickly you adapt. The tool will ask for your usual bedtime and wake-up time so it can create a personalized adjustment plan. If you’re someone who already has a flexible sleep schedule, you might adapt faster than someone with a rigid routine. The tool also considers whether you’re an early riser or a night owl, since shifting your sleep will be easier for some than others.
3. Choose Your Adaptation Speed: Everyone adjusts at a different pace. You’ll have the option to select whether you adapt slowly (1 hour per day), moderately (1.5 hours per day), or quickly (2 hours per day). Those of you who frequently travel or have flexible schedules may find they can handle faster adjustments, while those more sensitive to sleep disruptions may want to take a slower approach. Your selection determines how aggressively your sleep and wake times will shift before, during, and after your trip.
4. Generate Your Plan: Based on the information you’ve entered, the tool will create a customised sleep adjustment schedule. This isn’t a generic, one-size-fits-all guide, it’s tailored to your unique travel itinerary, sleep habits, and speed of adaptation. The plan will specify when you should start shifting your bedtime and wake-up times, when to expose yourself to bright light or avoid it, and whether melatonin supplements may help. It will also include strategic recommendations on meal timing and exercise to further accelerate your adjustment.
5. Follow the Recommended Adjustments: To make the transition as seamless as possible, the tool provides a step-by-step plan for adjusting your sleep schedule. If you have chosen jet lag prevention, you’ll begin shifting your routine before your trip so that by the time you arrive, you’re already adjusted. If you have chosen recovery, it will shift your schedule after you arrive. By following the schedule, you’ll minimise fatigue, reduce sleep disturbances, and sync with local time more efficiently.

This structured approach takes the guesswork out of managing jet lag. Instead of feeling groggy and out of sync for days, you’ll have a clear roadmap to help your body adjust quickly and smoothly. Whether you’re a frequent traveler looking for an edge or someone preparing for a once-in-a-lifetime trip, this tool will give you the strategy you need to feel your best when you land or recover from your trip.

The Science Behind Jet Lag Adjustment

Jet lag isn’t just about feeling tired, it’s a full-body phenomenon tied to your circadian rhythm, the internal clock that governs your sleep-wake cycles, metabolism, hormone production, and even body temperature. This rhythm is regulated by external cues, primarily light exposure, but also by meal timing, activity levels, and social interactions. When you cross time zones, your body struggles to adjust because its internal clock is still operating on your departure time, creating a misalignment between your biological night and the local time at your destination.

Chronobiologists, scientists who study biological clocks, have identified several strategies that help travelers adjust faster. These include gradually shifting sleep, controlling exposure to light, optimising hormone release, and using movement and diet to reinforce the new time zone.

By following a structured plan, you can resynchronise much more quickly than if you simply relied on time alone to do the work.

Gradual Sleep Shifts

One of the most effective ways to reduce jet lag is to pre-adjust your sleep schedule before traveling. If you’re traveling east, you need to advance your sleep (going to bed earlier); if you’re traveling west, you need to delay it (staying up later).

Most people can shift their circadian rhythm by 1 to 2 hours per day, though some may adjust faster. By gradually modifying your bedtime and wake-up time over the course of several days leading up to your departure, you make the transition smoother when you arrive. Alternatively, if you want to recover from jet lag, you can make this transition after you arrive. This is one of the key principles used in our Jet Lag Prevention and Recovery Tool.

Strategic Light Exposure

Light is the most powerful signal for resetting the biological clock. The suprachiasmatic nucleus (SCN) in the brain interprets light exposure as a cue for wakefulness, telling the body when it should be alert and when it should start winding down. To shift your body clock faster, you need to time your light exposure strategically.

• If traveling east (losing time): Get bright light in the morning at your destination. This helps shift your clock forward so that you feel tired earlier in the evening. Avoid bright light exposure in the late afternoon and evening, as it can delay your adjustment.
• If traveling west (gaining time): Get bright light in the evening to help delay your sleep cycle and make it easier to stay awake later. Avoid bright light in the early morning, as it will push your body clock earlier when you want it to stay later.

Sunlight is the most effective form of light exposure, but artificial light can also help. Light therapy boxes that emit 10,000 lux of light can be used in cases where sunlight isn’t available, such as during winter travel.

Melatonin and Sleep Aids

Melatonin is a naturally occurring hormone that signals to your body that it’s time to sleep. It’s secreted by the pineal gland in response to darkness. While your body produces melatonin on its own, taking a small supplement at the right time can help speed up adaptation to a new time zone.

Studies have shown that taking 0.5 to 3 mg of melatonin about 30–60 minutes before your target bedtime can assist in shifting your circadian rhythm. It’s particularly helpful for eastward travel, where advancing your sleep schedule is more difficult.

Unlike prescription sleep medications, melatonin doesn’t induce drowsiness in the same way, as it works by telling your body when it should start producing its own melatonin so it can better synchronise to this schedule. This means it’s not a sedative but rather a tool to help regulate your sleep cycle. However, melatonin should be used strategically and not overused, as excessive supplementation can potentially desensitise your natural melatonin receptors.

Meal Timing and Metabolism

Your circadian rhythm doesn’t just control sleep, it also regulates metabolism, digestion, and hunger hormones like ghrelin and leptin. Eating at the wrong times can throw off your adjustment just as much as sleeping at the wrong times.

• For eastward travel: Try to shift your meal times earlier by an hour or two each day leading up to your trip. Have a high-protein breakfast upon arrival to signal wakefulness.
• For westward travel: Delay meal times leading up to the trip and eat a later dinner upon arrival. Avoid heavy meals close to bedtime, as digestion slows down during sleep.

Some research suggests that fasting for 12–16 hours before breakfast in the new time zone may help reset your body clock faster. This approach, known as the Argonne Anti-Jet Lag Diet, is based on the idea that fasting can suppress circadian rhythms temporarily, allowing them to reset when eating resumes at the appropriate local time.

With my coaching clients, I haven’t found this to be super effective, but some people do find it to be beneficial.

Physical Activity and Sleep Pressure

Exercise also plays a role in regulating the body clock. Movement influences body temperature, cortisol levels, and alertness, which in turn affect sleep-wake cycles. Light to moderate exercise in the morning can help shift the clock forward, while evening workouts can delay it. However, vigorous exercise too close to bedtime may interfere with sleep due to increased adrenaline and core body temperature.

Even light movement, such as taking a walk outside, can be beneficial for reinforcing your new schedule. Sunlight exposure during this activity provides a double benefit, stimulating wakefulness while also helping with resetting the body clock.

Hydration, Alcohol, and Caffeine

Flying causes dehydration due to the dry air in airplane cabins, and dehydration can make jet lag symptoms worse. It’s important to drink plenty of water before, during, and after your flight. While it’s tempting to rely on caffeine to stay awake and alcohol to relax, both can interfere with circadian rhythms. Caffeine has a half life of ~six hours, so it should be avoided too late in the day, especially when traveling eastward.

Alcohol may help you fall asleep, but it disrupts REM sleep, which is essential for feeling rested. So drinking it will make you feel worse, and almost certainly make your jet lag worse.

Putting It All Together

Jet lag isn’t inevitable, you can actively manage it by making strategic adjustments. By taking all of these factors (sleep timing, light exposure, melatonin use, meal scheduling, exercise, and hydration) into account, you can create a comprehensive plan that aligns with your unique travel needs.

By following the recommendations of the tool and understanding the underlying science, you can drastically reduce the impact of jet lag and feel your best, no matter where you go.

Best Practices for Booking a Flight to Minimise Jet Lag

Preventing jet lag starts long before you board the plane or even before you begin shifting your sleep schedule. It begins with how you choose your flight. By strategically selecting flight times that align with your destination’s time zone, you can make the transition smoother and drastically reduce the severity of jet lag upon arrival.

1. Consider Your Destination’s Time Zone When Selecting a Flight

One of the biggest mistakes travelers make is booking flights purely based on convenience, without considering the time zone they’re traveling to. The goal should be to align your flight schedule with your destination’s local time, making the time shift easier on your body.

For example, if you’re flying from Dublin to New York, an 11 AM Dublin departure might seem like a reasonable morning flight. However, in New York time, that’s actually 7 AM, meaning you’ll be waking up and traveling during what would typically be an early morning for your new schedule (not to mention the fact you usually need to be at the airport 2-3 hours beforehand, so this is really a 4 AM event).

If your goal is to transition smoothly to New York time before departure, taking an early flight like this is just going to disrupt your sleep adjustment, making it harder to get on track once you land.

A better option in this scenario might be to book an afternoon or evening flight. This way, by the time you arrive in New York, it will be closer to nighttime, making it easier to sleep at the appropriate time and sync your body to the new schedule.

Remember, it is easier to stay awake for longer than it is to go to sleep earlier!

2. Choose Flights That Support Your Sleep Strategy

Your flight time should also support your sleep strategy. If you’re traveling eastward (e.g., from New York to Dublin), you’ll be losing time, so an overnight flight can be beneficial. Arriving in the morning allows you to push through the day, stay awake, and sleep at the right time for your destination.

If you’re flying westward (e.g., from Dublin to New York), you’ll be gaining hours. A daytime flight may work better, allowing you to stay awake during travel and get a proper night’s sleep upon arrival.

3. Avoid Flights That Land in the Middle of the Night

Flights that arrive in the early hours of the morning (e.g., 2-4 AM local time) can be particularly challenging, as you’ll land when everything is closed, your body may be fully awake, and it will be difficult to transition smoothly into the new schedule.

Try to book flights that land in the morning (if traveling east) or in the early evening (if traveling west) to make it easier to stay awake or sleep at the appropriate time.

4. Consider Layovers and Stopovers Carefully

Long layovers, especially in different time zones, can further disrupt your body clock. If possible, opt for direct flights to minimise extended travel times and unnecessary time zone confusion.

If a layover is unavoidable, choosing one that aligns with your new sleep schedule can help maintain rhythm and prevent unnecessary fatigue.

5. Use Red-Eye Flights Strategically

For shorter flights with a significant time difference, red-eye flights (overnight flights) can be useful. These flights allow you to sleep on the plane and arrive in the morning at your destination, reducing sleep debt and making it easier to adjust.

However, this only works if you’re able to sleep well on the flight. If not, you may end up exhausted, making jet lag even worse.

Booking a flight with jet lag prevention in mind requires more than just picking the cheapest or most convenient option. By choosing a flight time that aligns with your destination’s time zone, supporting your sleep strategy, and avoiding disruptive arrival times, you can drastically reduce the impact of jet lag and arrive feeling more refreshed and ready to go.
