With ultra-long non-stop flights on the rise, jet lag has become one of the biggest challenges for travellers. Even those booking cheap business and first class flights aren’t immune – the extra comfort might help you rest better in the air, but it won’t reset your internal body clock. That’s where science comes in, offering practical strategies to help you arrive refreshed and ready to go.
Here are a few ways to overcome jet lag after a long-haul flight.
Light exposure: the most powerful reset tool
Light is the main regulator of the body clock. Exposure to bright light at the right time can help your system speed up or slow down, depending on the direction of travel. Equally important is limiting light at the wrong time – sunglasses in the morning after westward travel, or avoiding screens late at night can make a real difference in resetting your rhythm.
Strategic sleep and napping
When you sleep before, during, and after your flight matters just as much as how long you sleep. Adjusting your bedtime in the days leading up to departure can give you a head start – going to bed earlier if you’re flying east, or later if you’re heading west. On the plane, keep naps short at around 20–30 minutes to take the edge off fatigue without making it harder to adapt on arrival. Once you’ve landed, resist the temptation for long daytime naps, and use simple tools like a sleep mask or earplugs to block out noise and light for better quality rest.
By pre-adjusting your schedule and managing naps carefully, you can give your body a head-start in adapting to your new time zone.
Nutrition and hydration
What you eat and drink also affects your circadian rhythm. Heavy evening meals can interfere with sleep, so it’s best to keep things light before bed, while a protein-rich breakfast the following morning can help boost alertness. Staying hydrated is just as important – cabin air is notoriously dry, so sip water regularly and be mindful of alcohol and caffeine, both of which can worsen fatigue.
Increase melatonin intake
Melatonin, a hormone released naturally at night, signals to the body that it’s time to sleep. Taken in small, timed doses, it can help to reset your internal clock. Think of it not as a sleeping pill, but as a gentle nudge towards aligning with your new schedule. Combined with good sleep hygiene – like limiting screens before bed and seeking natural sunlight in the morning – it can ease the adjustment process.
Exercise and movement
Exercise can also play a role in resetting your body clock by influencing core temperature cycles. A gentle jog in the morning is particularly useful after eastward travel, helping your system adjust more quickly, while an evening walk can delay sleep if you’re heading west. Even small movements during the flight – like walking the aisle or doing simple stretches and ankle rotations – improve circulation and reduce stiffness, making you feel more energised when you land.
Chronotherapy: training your body clock
For frequent travellers or anyone on a tight schedule, chronotherapy is worth considering. This means gradually shifting your sleep and wake times in the days before departure – for example, moving them forward by an hour each day if you’re heading several hours east.
Technology and tools
Apps and wearable tech can now provide personalised advice based on circadian science. By combining these tools with light exposure management and smart screen use, you can plan ahead and reduce jet lag more effectively than ever before.
Psychological and behavioural adjustments
Your mindset plays a role too. Stress and negative thinking can make jet lag feel worse, so relaxation techniques like deep breathing, meditation, or mindfulness during the flight can help. Focusing on adjusting to local time – rather than worrying about “lost sleep” – can ease the transition.
Long-haul travel doesn’t have to mean days of foggy thinking and sleepless nights. With the right mix of light management, nutrition, melatonin, and forward planning, you can cut jet lag symptoms significantly and make the most of your time away. Now, all that’s left to do is focus on how you can make your long-haul flight more enjoyable, whether that means packing your favourite snacks or planning ways to stay entertained during a long flight.
