Jetting off on the holiday of a lifetime is one of the best feelings in the world, but spending the first few days battling jet lag? Not so much. We ask an expert how to avoid jet lag on long haul flights so you can make the most of your trip.
What is jet lag?
Also known as ‘desynchronosis’ and ‘flight fatigue’, jet lag is a temporary disorder that causes fatigue, insomnia and sometimes other symptoms, as a result of air travel across different time zones.
It’s caused by a disruption to your circadian rhythm – the internal body clock that governs your daily sleep-wake pattern.
Besides fatigue and insomnia, unlucky travellers may experience a number of physical and emotional effects, including anxiety, constipation, diarrhoea, confusion, dehydration and headaches. In other words: It’s not a fun start to your summer break.
But can you avoid this one-way ticket to exhaustion? We asked experts for their top tips for banishing post-flight fatigue…
How to avoid jet lag on long haul flights
1. Stay hydrated and ditch the coffees
Before a flight, it can be tempting to load up on wine and beer to calm your nerves (or toast the holiday!), or caffeinated drinks to keep you awake. But this could be doing more harm than good.
“Hydration can be key,” says Dr Ali Hill, Applied Human Nutrition course leader at Solent University. Your body recovers best when it isn’t depleted of fluids. “Tea, coffee (if you’re not used to them) and alcohol can dehydrate you, depending on what type you have,” Hill adds.

When it comes to choosing from the drinks trolley mid-flight, she suggests sticking to plain water. Artificial stimulants will affect your ability to sleep and increase jet lag recovery time.
“Drink enough water to make sure your urine is a pale straw colour. You might also find that you get more dehydrated when you’re flying and need to drink more than normal.”
2. Adjust your sleep pattern slowly
There are some sleeping strategies you can implement before you go away to help ease you into the change of time zones when you arrive. A few days before your flight, Hills suggests gradually adjusting your bedtime. Earlier if you’re flying east, or later if heading west.
“By beginning to shift your sleep schedule early on, you’ll feel more energised to get up and get going even on that first day,” agrees Neil Robinson, Sealy UK sleep expert.
There are online tools that can help you to plan the shift. A Jet Lag Calculator is really helpful. It analyses the number of time zones your flight crosses in order to work out how many hours you’ll have to shift your body clock.
3. Turn off gadgets
When you arrive at your destination, it can be really tempting to start updating your social media channels and checking up on the day’s news. But if you’re planning to get some shut-eye, this can really throw off your sleep schedule.
The blue light emitted by your device can trick your brain into thinking it’s daytime even when it’s not.
“If you find yourself awake late in the evening, choose a light evening meal and stretch your legs outdoors instead,” says Bahee Van de Bor, a specialist paediatric dietitian at ukkidsnutrition.com. “Switch off electronic gadgets and read a book to help you fall asleep.”
If you really can’t go without the devices, consider a back-lit kindle such as the Kindle Paperwhite (available on Amazon). To make the screen darker, invert the colours so you’re reading white on black, and turn the brightness down to the lowest level you can still read. It will also help save precious space in your luggage.
4. Bring your own pillow
“Try to maintain your personal sleep routine while you’re away from home,” says Professor Kevin Morgan, director of the Clinical Sleep Research Unit at Loughborough University. “Make time to set out your bedtime stuff, such as your pyjamas and toilet bag, so that things will be ready when you return for the night.”
Morgan says that this has the important effect of familiarising you with your new sleep environment.
“Also, try to preserve your pre-sleep habits and routines,” he adds. “These are important behavioural cues for sleep, so make sure you pack any items which support these behaviours. For example, photos, books, blankets or teddy bears – and consider taking your own pillow.”
5. Adjust your watch
A simple but effective trick you can do during your flight is to change your watch, phone and laptop to match the time of your destination. This will mentally prepare you for the new time zone you’re about to enter.

“Imagine what you would be doing at your destination and try to mimic that as much as possible, especially meals and bedtime,” advise Ruth Tongue and Lucy Faulks, founders of Elevate. “You’ll be amazed at how quickly shifting your mind’s perspective and small actions can help your body adjust to the changes.”
6. Snack on cherries
Struggling to sleep in your hotel? Instead of ordering room service, try and find a local fruit vendor. Montmorency tart cherries are one of the few natural sources of melatonin. That’s the hormone responsible for the regulation of the body’s internal clock and sleep-wake cycle.
“Cherries can help improve sleep quality, including sleep efficiency, the number of awakenings at night, nocturnal activity and actual time spent sleeping,” says Emma Derbyshire, a nutritionist speaking on behalf of British Cherries.
To reap the benefits, have either a handful of cherries as a bedtime snack, or swill down a small serving of tart juice. You might just find that it stops you from staring at the ceiling all night and helps you avoid jet lag on long haul flights.
