Jet Lag Blues? 7 Proven Tips to Bounce Back Faster!
Share
Jet lag occurs when your body’s internal clock, or circadian rhythm, is thrown out of sync due to rapid travel across time zones. Your body operates on a roughly 24-hour cycle that governs not just sleep, but also appetite, digestion, body temperature, and hormone release (Zhu et al., 2020). When you travel quickly across multiple time zones, your internal clock lags behind the local time, leading to feelings of fatigue, difficulty concentrating, digestive issues, and sleep problems.
Jet lag can hit hard, but with the right strategies, you can minimize its impact. Below are seven tips to help you overcome jet lag more quickly and start feeling like yourself again.
1. Start Adjusting Your Schedule Before You Leave
One of the best ways to reduce jet lag is to gradually shift your schedule before you even board the plane. By making small changes in the days leading up to your trip, you can help your body adapt to the new time zone more smoothly.
Tip: If you’re traveling east (losing time), start going to bed and waking up an hour earlier each day for a few days before departure. If traveling west (gaining time), do the opposite—stay up and wake up later. A study published in the Journal of Biological Rhythms found that gradually adjusting sleep schedules before travel can significantly reduce the severity of jet lag (Shirai et al., 2017).
2. Use Strategic Light Exposure
Light is the most powerful tool for resetting your internal clock. The timing of light exposure is key to adjusting to a new time zone. Bright light, particularly in the morning, helps signal to your brain that it’s time to be awake and alert. On the other hand, avoiding bright light during the evening can help your body wind down.
Tip: Upon arrival, get outside and soak up natural sunlight, especially in the morning if you’re trying to wake up earlier. If you're arriving late at night, avoid bright light exposure and opt for dim lighting to help your body wind down for sleep. Research from The Journal of Clinical Sleep Medicine supports the use of light therapy to combat jet lag by influencing circadian rhythms (Burgess et al., 2003).
3. Stay Hydrated During and After Your Flight
Dehydration can make the symptoms of jet lag worse. Airplane cabins have low humidity, which can lead to dehydration if you don’t drink enough water during your flight. Dehydration intensifies fatigue, headaches, and dizziness—all symptoms that jet lag already causes.
Tip: Drink plenty of water before, during, and after your flight. Avoid alcohol and caffeine, which can further dehydrate you. A study from Aviation, Space, and Environmental Medicine suggests that staying hydrated can reduce the severity of jet lag symptoms, particularly after long-haul flights (Drew et al., 2008).
4. Take Short Naps (But Time Them Wisely)
While the temptation to crash and sleep for hours as soon as you arrive might be strong, long naps can make jet lag worse by further confusing your internal clock. Instead, take short naps of 20-30 minutes to refresh yourself without derailing your sleep schedule.
Tip: If you're feeling exhausted after your flight, take a short nap but avoid long sleep stretches during the day. Make sure to time your nap to complement your new schedule rather than disrupt it. A study published in Sleep found that controlled naps can help ease jet lag symptoms when timed appropriately, without interfering with nighttime sleep (Waterhouse et al., 2007).
5. Be Smart About Caffeine
Caffeine can be a double-edged sword when dealing with jet lag. On one hand, a well-timed cup of coffee can give you the energy boost you need to get through a sluggish afternoon. On the other hand, overdoing it or drinking caffeine too late in the day can interfere with your sleep and prolong jet lag symptoms.
Tip: Use caffeine strategically. Enjoy your morning coffee to help you power through fatigue, but avoid it in the afternoon and evening to prevent disrupting your nighttime sleep. A study in The Journal of Physiology showed that consuming caffeine late in the day can shift the body’s internal clock by as much as 40 minutes, which can exacerbate jet lag (Burke et al., 2015).
6. Melatonin Supplements for Sleep Regulation
Melatonin is a hormone that regulates sleep-wake cycles, and your body produces it in response to darkness. When crossing time zones, your natural melatonin production can be disrupted. Melatonin supplements can help reset your circadian rhythm by signaling to your brain that it’s time to sleep.
Tip: If you're traveling east and need to fall asleep earlier, consider taking melatonin supplements 30-60 minutes before your desired bedtime. A meta-analysis in PLOS Medicine found that melatonin supplements are highly effective in reducing the duration and severity of jet lag (Herxheimer & Petrie, 2002). However, use melatonin cautiously and consult with a healthcare provider if needed.
7. Stay Active (But Avoid Overexertion)
Exercise can be a great way to boost your energy levels, improve circulation after a long flight, and help regulate your sleep-wake cycle. However, intense workouts right before bedtime can be counterproductive, as they may elevate your heart rate and make it harder to fall asleep.
Tip: Aim for light to moderate physical activity, such as walking, swimming, or yoga, especially in the morning or early afternoon. A study published in the Journal of Applied Physiology found that morning exercise helps shift the circadian clock, making it easier to adjust to new time zones (Buxton et al., 2003). Avoid vigorous exercise in the evening to prevent interfering with sleep.
Additional Tips for Easing Jet Lag
- Eat According to Local Time: Eating meals at local times can help your body adjust more quickly. Your digestive system is closely tied to your circadian rhythm, so matching your eating schedule to your new time zone can aid in faster acclimatization.
- Avoid Heavy Meals Before Bed: Eating a large meal right before sleep can cause indigestion and disrupt sleep. Opt for lighter meals closer to bedtime, and save your larger meals for earlier in the day.
- Reset Your Watch and Mindset: As soon as you board your flight, set your watch to the time at your destination. Mentally preparing yourself for the new time zone can help reduce the psychological effects of jet lag.
Jet lag doesn’t have to put a damper on your travel experience. With the right strategies—such as adjusting your schedule ahead of time, managing light exposure, and staying hydrated—you can minimize the impact and start feeling like yourself again sooner. Whether you’re flying across the globe or just a few time zones away, these seven tips can help you recover faster and enjoy your trip to the fullest.
