This guide breaks down exactly how to recover from long flights using targeted sleep, hydration, and movement strategies so you can arrive, adapt, and perform at your best instead of losing days to jet lag.
Plan your sleep and light exposure around your destination time zone, not your departure city.
Start hydrating before you fly and use electrolytes and small, frequent fluids after landing.
Use gentle, frequent movement and mobility work in the first 24–48 hours to reduce stiffness, swelling, and fatigue.
What you do in the first evening after landing (nap length, bedtime, light, caffeine) strongly shapes your recovery.
Create a simple 48-hour recovery routine so travel stops derailing your energy, mood, and performance.
This guide is organized around the three levers that have the biggest evidence-based impact on travel recovery: sleep and light exposure, hydration and nutrition, and movement and circulation. Within each, you’ll get time-based steps for the first 0–6 hours, 6–24 hours, and 24–48 hours after you land, plus targeted tips for business travel, night flights, and red-eyes.
Long flights disrupt your body clock, drain fluids, and reduce circulation, causing jet lag, brain fog, and stiffness. Instead of waiting days to feel normal, you can use a structured plan to reset faster, protect your health, and get more out of your trip—whether you need to perform at work or simply enjoy your time away.
As soon as you land, mentally and behaviorally commit to your destination time. Change your watch, phone, and calendar. Eat, move, and sleep according to local time, not “what time it is back home.” This accelerates circadian re-alignment and reduces the duration of jet lag.
Great for
If you land in the morning or early afternoon, spend 20–45 minutes outside in daylight within 1–2 hours of arrival. Light tells your brain it’s daytime and suppresses melatonin so you feel more awake. If you land at night, keep lights dim, avoid bright screens, and head toward a normal local bedtime.
Great for
If you must nap, limit it to 20–30 minutes and finish at least 6 hours before your planned bedtime. Longer or late naps can delay your sleep onset, extend jet lag, and leave you groggy. Set an alarm, darken the room slightly, but avoid deep blackout conditions for naps.
Great for
Eat a light to moderate meal at local dinnertime with protein, fiber, and some complex carbs. Avoid heavy, greasy meals and excessive alcohol, which disturb sleep and digestion. Example: grilled fish or tofu, vegetables, and rice or potatoes. This helps stabilize blood sugar and supports overnight recovery.
Great for
Wake at a reasonable local time (even if you slept poorly) and get 20–30 minutes of daylight exposure as soon as you can. Repeat this for the first 2–3 mornings. A fixed wake time and morning light are among the strongest tools to reset your internal clock.
Great for
Aim for a glass of water upon waking, then steady intake throughout the day. Include 1–2 servings of electrolytes if you still feel depleted or are in a hot climate. Monitor urine color: pale yellow generally signals good hydration for most people.
Great for
For flights crossing more than 3–4 time zones, look up the destination time during your flight and loosely plan when you’ll try to sleep and stay awake on board. For eastward travel, it often helps to start sleeping earlier on the plane; for westward travel, you may stay awake longer to match destination evening.
Great for
To adjust earlier (typical when flying east), emphasize morning light and avoid bright evening light. To adjust later (common when flying west), use evening light and sometimes avoid very early morning light. Consistency over several days matters more than perfection on one day.
Great for
Thirst can lag behind your actual hydration status. Use simple anchors: a glass of water upon arrival, with each meal, and after each extended walk. If you’re prone to headaches or you flew for more than 6–8 hours, consider adding electrolytes once or twice in the first day.
Great for
Sugary drinks and pastries can create energy crashes and worsen jet lag. Prefer water, unsweetened tea, or coffee with minimal sugar. Pair caffeine with food to reduce jitters and avoid using it to “push through” late into the local night.
Great for
Instead of one long workout, sprinkle movement throughout your first day: 5–10 minute walks, a few sets of calf raises, shoulder rolls, and gentle hip openers. These frequent cues help your lymphatic system clear fluid and reduce stiffness.
Great for
Long flights tighten hip flexors, compress the lower back, and restrict calf movement. Target these areas with lunges or hip flexor stretches, cat–cow spinal mobility, and calf stretches on a step or against a wall.
Great for
Recovery from long flights is less about a single magic tactic and more about aligning multiple small cues—light, movement, meals, and sleep—consistently with your destination time zone.
The first 24 hours after landing function like a “reset window”: what you do with naps, bedtime, light exposure, and hydration during this period heavily influences how many days of productivity or enjoyment you gain or lose.
Frequent travelers benefit from having a repeatable personal protocol—pre-planned sleep strategy, hydration routine, and movement pattern—so travel becomes a manageable stressor rather than a disruptive event.
Frequently Asked Questions
A common estimate is about one day of adjustment per time zone crossed, but using targeted light exposure, consistent wake times, and careful control of naps, caffeine, and bedtime routines can often shorten this. Many people notice meaningful improvement within 2–3 days when they follow a structured recovery plan.
If you arrive in the morning, it’s usually better to avoid a long sleep. A short, early nap of 20–30 minutes can help take the edge off, but aim to stay awake until a normal local evening bedtime. Going straight into a long sleep can prolong jet lag and delay adaptation.
Needs vary by person and climate, but a useful guideline is to start with 500–750 ml of water with electrolytes in the first few hours after landing, then continue with regular water intake across the day. Aim for pale yellow urine as a practical indicator of adequate hydration for most people.
Short-term melatonin can help shift sleep timing, especially for eastward travel, but dose and timing matter. Lower doses taken 1–2 hours before your planned local bedtime are often effective. If you have medical conditions, take other medications, or are pregnant or breastfeeding, speak with a healthcare professional before using melatonin.
You can, but it’s often not ideal. Fatigue, dehydration, and disrupted coordination can increase injury risk and reduce performance. Most people recover better by prioritizing light to moderate activity—walking, easy cardio, and mobility—for the first 24–48 hours, then resuming full-intensity training once sleep and hydration are normalized.
Long flights don’t have to cost you days of energy and focus. By anchoring quickly to local time, using light and sleep strategically, rehydrating with intention, and prioritizing gentle movement over hero workouts, you can reset much faster. Before your next trip, turn these steps into a simple personal checklist so arriving ready to go becomes your new normal—not the exception.

Airplane cabins are very dry, and you typically lose more fluid through breathing and limited drinking. In the first hours after landing, aim for 500–750 ml of water with electrolytes, sipped gradually. Avoid guzzling huge amounts at once, which can lead to more bathroom trips and lower absorption.
Great for
Walk for at least 10–20 minutes soon after you arrive at your accommodation or office. Follow with 5–10 minutes of gentle mobility: ankle circles, calf stretches, hip flexor stretches, shoulder rolls, and twisting through your spine. This helps circulation, reduces swelling, and signals to your body that the inactivity phase is over.
Great for
If it’s morning or early afternoon locally and you’re extremely sleepy, moderate caffeine (one coffee or tea) can help you stay awake and adapt. Avoid caffeine within 8–10 hours of your intended local bedtime to prevent wrecking your first night of sleep.
Great for
Recreate your best at-home sleep habits: cool room (around 18–20°C), dark curtains or a sleep mask, and minimal noise (earplugs or white noise). Keep screens dim and ideally off 60 minutes before bed. These signals help your brain override the confusion from time zone changes.
Great for
If you get drowsy too early in the evening, use gentle movement (a walk, light stretching) and brighter indoor lighting to push your bedtime closer to local norms, rather than reaching for caffeine or heavy snacks.
Great for
Melatonin can help shift your body clock, but timing and dose matter. For eastward travel where you need to fall asleep earlier, low doses (0.5–3 mg, depending on local guidelines) taken 1–2 hours before target bedtime may help. It’s best used short term and ideally under guidance if you have any health conditions.
Great for
Unless you’re used to training through travel, avoid maximal or new workouts in the first 24–48 hours. Prioritize walking (6,000–10,000 steps if realistic), low to moderate intensity cardio, and light strength or mobility. This reduces injury risk when your coordination and sleep are off.
Great for
Flights often slow digestion and cause bloating. Eat fiber-rich foods (fruits, vegetables, whole grains), sip fluids, and keep moving. If your legs were swollen, elevate them for short periods and continue light calf and ankle movements.
Great for
Try to keep meal times, caffeine timing, movement, and bedtime fairly consistent for at least two days. This reduces circadian confusion and helps your body relearn the new schedule quickly.
Great for
Treat your first two nights like important appointments: limit late social events, heavy meals, and alcohol. Use your normal wind-down cues—reading, stretching, breathing exercises, or a warm shower—to signal sleep time to your brain even in a new environment.
Great for
Waking up at odd times is normal after time zone shifts. If you wake too early, stay in bed in the dark or dim light, use calm breathing, and avoid bright screens. If you can’t fall back asleep after ~20–30 minutes, get up briefly in low light, read or relax, then try again. Avoid checking work messages.
Great for
Start eating at local meal times as soon as possible, even if you’re not perfectly hungry. A lighter meal is fine, but that simple act signals to your body that this is the new rhythm. Avoid constant snacking at “home time” hours overnight.
Great for
Travel often means unfamiliar foods plus dehydration, a combo that can upset your gut. Start with simple, familiar options: yogurt or fermented foods if tolerated, fruits like bananas or berries, cooked vegetables, and lean proteins. Add fiber gradually if you feel backed up.
Great for
Alcohol plus altitude and dehydration hits harder. After landing, if you choose to drink, keep it moderate, have it with food, and avoid drinking close to bedtime. Alcohol disrupts sleep architecture and can significantly worsen jet lag.
Great for
If you’re exhausted, under-slept, and mildly dehydrated, this is not the day to test your limits. Keep intensity at a 5–7 out of 10, reduce volume, and avoid heavy new exercises. You’ll adapt faster by training smart, not hard, in the first 48 hours.
Great for
If your legs or ankles swell after flying, compression socks during and shortly after flights plus occasional elevation can help. Combine with frequent walking and ankle circles. Seek medical advice if swelling is severe, painful, or one-sided.
