Natural Ways to Prevent Jet Lag on Long-Haul Flights

If you have ever travelled long distances and found yourself wide awake at 3 a.m. or struggling to stay alert during the day, you’ve likely experienced jet lag. According to the UK Department for Transport, people in England spent on average 362 hours travelling in 2024  that’s roughly an hour every day  illustrating how common and inevitable long journeys have become.  

When your internal body clock is out of sync with the local time at your destination, it affects sleep, mood, concentration and even digestion. The more time zones you cross, the stronger the effect tends to be  especially when flying eastward, which tends to be harder to adjust to than flying westward. The good news is that there are natural ways to reduce its impact and make your trip smoother. 

Jet lag occurs when your body’s natural rhythm, known as the circadian rhythm, doesn’t match the time zone you’ve moved to. This affects sleep, mood, concentration, and even digestion. The more time zones you cross, the stronger the effect tends to be. Eastward travel (such as from London to Asia) is often harder to adjust to than westward travel, because you lose hours rather than gain them. 

Preparation is one of the best forms of jet lag prevention. Simple steps taken a few days before you travel can make a big difference. 

Try shifting your bedtime and waking time closer to your destination’s time zone in the days leading up to your trip. This helps your body adapt more smoothly. 

It may sound obvious, but being overtired before you fly can make jet lag worse. Aim for a consistent sleep routine before your flight. 

Avoid heavy or greasy foods before you travel. Lighter meals with lean proteins, fruit, and vegetables support digestion and prevent bloating during long flights. 

If you’re travelling abroad, speak with one of our pharmacists at Pearl Chemist Group for personalised travel health advice. They can recommend helpful travel essentials such as rehydration sachets, motion sickness tablets, and natural jet lag remedies available in the UK. 

There are several ways to support your body naturally while you’re in the air. 

• Stay hydrated: Cabin air is dry and can cause dehydration, which makes fatigue worse. Drink plenty of water and limit alcohol or caffeine, as both can disturb your sleep patterns. 
• Move around regularly: Walk up and down the aisle when it’s safe to do so, or stretch your legs at your seat. This improves circulation and helps you feel more energised on arrival. 
• Create a calm environment: Earplugs, an eye mask, or noise-cancelling headphones can help you relax and rest more easily during the flight. Listening to calming music or guided breathing exercises can also promote better rest. 
• Consider natural sleep support: Some people find that herbal options such as chamomile tea or lavender oil help them unwind. If you’re unsure what’s suitable for you, our pharmacists can advise you on safe, natural cures for jet lag that are available over the counter in the UK. 

Once you reach your destination, the goal is to reset your internal body clock as quickly as possible. 

Natural sunlight is one of the best ways to signal to your brain that it’s time to be awake. Try to spend time outdoors during the local daytime hours. 

Even if you feel exhausted, try not to nap for long periods. A short nap of 20–30 minutes can help you recharge without making it harder to sleep later. 

Eating breakfast, lunch, and dinner at local times helps your body adjust. Avoid eating late at night, as this can confuse your sleep cycle. 

While a cup of tea or coffee can perk you up, drinking too much late in the day may interfere with your ability to fall asleep at night. 

If you struggle to fall asleep in a new time zone, speak with our pharmacists. They can suggest gentle, natural options such as melatonin supplements (where suitable), herbal teas, or magnesium tablets, which some travellers find helpful for relaxation. 

A few well-chosen items can make managing jet lag and overall travel health easier. You can find many of these essentials at Pearl Chemist Group pharmacies or online. 

• Rehydration sachets – Replace lost electrolytes and help your body recover from the dehydrating effects of long flights.
• Tisserand Sleep Better Pulse Point Roller Ball – This natural essential oil blend can be applied directly to your pulse points to ease restlessness and encourage relaxation. 
• Herbal travel calm tablets – Herbal calm tablets may help reduce mild travel anxiety and restlessness during long journeys. 
• Eye masks and earplugs – Blocking out light and noise can help you rest better in unfamiliar environments. The Essentials Gel Eye Mask provides cooling relief for tired eyes while reducing puffiness and soothing discomfort, making it easier to relax and sleep wherever you are. 
• Motion sickness bands – These are useful if you experience nausea or dizziness while travelling, helping you stay comfortable during your journey. 

Our pharmacists can help you build a personalised travel kit suited to your trip length and destination, ensuring you have everything you need for a smoother, more restful journey.

Yes, herbal supplements such as valerian, chamomile or magnesium are sometimes used as natural jet lag remedies to support relaxation and sleep. But their effects vary from person to person. Always ask our pharmacist before using them with any other medications or if you have health conditions. 

Travelling east tends to make jet lag worse because you “lose” hours. Try shifting your sleep earlier in the days before your flight, use morning light exposure on arrival, and stay awake until local evening—these are among the most effective jet lag prevention tips. 

Yes. Our pharmacists may recommend gentle over-the-counter options such as herbal sleep aids, magnesium supplements, or relaxing teas to support better rest. These are among the most accessible natural jet lag remedies UK travellers often rely on for adjusting to new time zones. 

Typically, jet lag may last 1 to 3 days, sometimes longer depending on how many time zones you crossed. If symptoms like extreme fatigue or confusion persist beyond a week, it’s wise to seek professional advice. 

Absolutely. Getting natural daylight, especially at the right times  morning or afternoon depending on your direction of travel  helps reset your circadian rhythm. This is one of the most reliable natural cures for jet lag. 

Melatonin can sometimes be useful, especially when crossing five or more time zones, but it’s prescription-only in the UK in many cases. Many travellers prefer non-medicated strategies first (sleep shifting, light exposure, hydration) before considering any supplement with pharmacist guidance.
