Most travellers from Gujarat meet jet lag properly on their first long westbound trip — a European or American holiday where the first two days disappear into a fog of three in the morning wakefulness and four in the afternoon collapse. It is a genuine shame, because those are days you paid for. What makes it worse is that most of the advice people arrive with is folklore: drink lots of water, try to sleep on the plane, push through on arrival. Some of that helps a little. None of it addresses the actual mechanism, which is simpler and stranger than tiredness.
Jet lag is a mismatch between your internal body clock and local time. Your circadian rhythm — the roughly twenty-four-hour cycle that governs when you feel alert, when you feel sleepy, when you are hungry and when your core temperature dips — is anchored primarily by light. Fly across six time zones and that clock stays on Indian Standard Time for a while, drifting back into alignment at somewhere between one half and one full time zone per day. Everything that genuinely works is about dragging that clock across faster, and the strongest lever you have is not caffeine or melatonin. It is when you let light hit your eyes.
Why flying west is easier than flying east
This is the piece of the puzzle that explains why the same eight-hour flight ruins one trip and barely dents another. The human body clock naturally runs slightly longer than twenty-four hours, which means it finds it easier to stretch a day than to shorten one. Flying west — India to Europe, the UK or North America — asks you to stay up later and get up later, which is the direction your body already leans. Flying east — India to Japan, Korea, Australia or back home from the Americas — asks you to fall asleep before your body is ready, which is much harder to force.
The practical consequence is that you should plan the two halves of a trip differently. Going to Europe, expect one groggy day and a broadly normal second day. Coming home from a US holiday, or landing in Tokyo, expect the adjustment to take noticeably longer and do not schedule anything that demands sharpness on the first morning. Travellers who know this stop blaming themselves for a slow start on the eastbound leg, and start building the itinerary around it instead.
Start shifting before you fly
You do not need to do anything dramatic, and the elaborate four-day pre-adjustment schedules that circulate online are more than most holidays justify. But moving your bedtime by thirty to sixty minutes a day for the two or three days before departure, in the direction of your destination, takes a real bite out of the adjustment. Heading west, go to bed and get up an hour later than usual. Heading east, an hour earlier. Shift your meals with your sleep, because the timing of food is a secondary clock signal in its own right.
Set your watch and phone to destination time when you board, not when you land, and start thinking in that time immediately. It sounds like a gimmick and it is not: the decision of whether to sleep on the aircraft should be made against destination time rather than against how tired you feel. On an overnight flight from an Indian metro to Europe, arriving early morning, sleeping on the plane is the whole game. On a daytime eastbound flight arriving in the evening, staying awake so you can sleep on landing is the better trade even though the cabin lights are off and everyone around you is dozing.
Light: when to seek it and when to hide from it
This is the lever worth learning properly. Broadly, after a westward flight you want bright light in the local late afternoon and early evening, which pushes your clock later and helps you stay up until a local bedtime. After an eastward flight you want bright morning light, which pulls your clock earlier, and you want to avoid bright light in the late evening. Getting this backwards actively delays adjustment, which is why the traveller who lands in Europe and takes a long afternoon nap in a dark hotel room often feels worse on day two, not better.
The cheapest and most effective version of this is a walk outdoors at the right hour. Daylight, even on an overcast day, is dramatically brighter than indoor lighting, and forty-five minutes of it is worth more than any pill. In the wrong window, sunglasses and staying indoors are the tools. If you are travelling with older parents, this is doubly worth planning around, because adjustment tends to slow with age — our guide to travelling abroad with senior citizens and parents from Gujarat covers pacing an itinerary so the first two days are gentle rather than packed.
The nap rule, and the one mistake almost everyone makes
The single most common self-inflicted wound is the arrival nap that turns into four hours. You land in the morning, you are wrecked, you lie down at noon intending to rest your eyes, and you wake at six in the evening having comprehensively destroyed your chance of sleeping that night. The rule that saves the trip: if you must nap on arrival day, keep it to twenty or thirty minutes, set two alarms, and do not nap after the local mid-afternoon. A short nap takes the edge off without eating into the sleep pressure you need to fall asleep at a local bedtime.
Then aim to stay up until a plausible local hour — not necessarily your normal bedtime, but nothing earlier than about nine in the evening — and get up at a normal local time the next morning even if the night was poor. One firm morning anchor is worth more than a perfect night. The second night is almost always dramatically better than the first, and knowing that in advance stops people from panicking and reaching for sedatives on night one.
Caffeine, alcohol, melatonin and what the evidence supports
Caffeine is a genuine tool and a genuine trap. It is useful in the local morning and early afternoon to hold you awake through the trough, and it is counterproductive within about six hours of when you want to sleep, because it lingers far longer than most people assume. Alcohol is worth being honest about: it may help you fall asleep on the aircraft, but it fragments sleep quality badly and dehydrates you, and the net effect on jet lag is negative. Skipping it on the flight is one of the more reliable small wins.
Melatonin is the supplement with the most support behind it for eastward travel in particular, taken in the destination's evening to nudge the clock earlier. Two honest caveats, though. Timing matters more than dose, and taken at the wrong hour it can shift your clock the wrong way. And its regulatory status varies widely between countries — it is freely available over the counter in some and prescription-only or restricted in others. Talk to your doctor before you rely on it, carry it in original packaging with the prescription if you have one, and read our notes on carrying prescription medicines across borders before you pack anything medicinal. Nothing in this article is medical advice, and anyone with a heart condition, diabetes, epilepsy or a pregnancy should take the question to their own doctor rather than to a travel blog.
Hydration, movement and the cabin itself
Cabin air is dry and the cabin is pressurised to an altitude equivalent of a couple of thousand metres, which is enough to leave you feeling flat even before the time zones get involved. Drinking water steadily rather than in gulps, getting up to walk every couple of hours, and doing simple ankle and calf movements in your seat all help — the last of these matters for circulation on long sectors, not just for comfort. Compression socks are worth it on anything over about eight hours, and are strongly worth discussing with a doctor if you have any history of clots.
Seat choice earns its money on long-haul more than on any other flight. A window seat gives you something to lean on and control over the shade, which is exactly the light-management tool you want. An aisle seat gets you up and moving without disturbing anyone, which suits travellers who need to stretch. If a long layover is part of the routing, a lounge with a shower transforms the arrival — our guide to airport lounge access for Indian travellers explains which cards and passes actually get you in, and a shower before the final leg is worth more than an extra hour of bad sleep.
Choosing flights that leave you in better shape
Some of the recovery is decided at booking. For westbound travel to Europe, an overnight departure that lands in the morning gives you a full first day if you can sleep on board, though it punishes you badly if you cannot. A daytime arrival in the early evening is the gentler option for poor aircraft sleepers, because you go almost straight to a local bedtime. For long eastbound sectors, arriving in the late afternoon or evening is usually kinder than a dawn arrival that leaves you facing an entire day on no sleep.
Fewer connections generally beat a marginally cheaper itinerary with two stops, and a single long layover in a good airport beats two short anxious ones. Where budget forces a compromise, put the money into the sector you will sleep on. If you are weighing routings and fares for a first big trip, our first international trip checklist for travellers from Gujarat walks through the booking decisions in order, and the international trip budget planner helps you see what the better routing actually costs.
Frequently asked questions
How long does jet lag actually last? A common rule of thumb is about a day of adjustment per time zone crossed, faster going west and slower going east. Most people feel broadly normal within two to four days on a typical India-to-Europe trip, and it is usually the first night and the first afternoon that are worst.
Is it worth trying to adjust for a short trip? Often not. For a two or three-night business trip across many time zones, some travellers do better staying on Indian time entirely — sleeping and eating on home hours where the schedule allows — rather than half-shifting and arriving home misaligned in both directions. For a holiday of a week or more, shifting properly is clearly worth it.
Does jet lag affect the return journey differently? Yes, and travellers consistently underestimate this. Coming home from Europe or the Americas is an eastward flight, which is the harder direction, so plan a buffer day before returning to work rather than landing in the morning and going to the office.
Do children get jet lag? They do, and they often adjust faster than adults — but they also lose their tempers harder while adjusting. Keep the first day light, get them outdoors in daylight, and hold bedtime as close to local as you can manage. For very young travellers, our guide to flying internationally with babies and infants from India covers the practicalities in more depth.
None of this makes long-haul effortless, but it reliably converts two wasted days into one slow morning. The other half of the answer is an itinerary that does not schedule a six-hour coach tour for the morning after a fourteen-hour flight, which is where a planner who has actually flown the route earns their fee.
