How to avoid jet lag when you're flying long-haul for your summer holidays

Time-zone tiredness can put a damper on long-haul holidays, so are there ways of combating jet-lag? We sought expert advice

Long haul flights are tiring enough before you factor in jet lag so it pays to be as prepared as possible

JETTING off on the summer 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.

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 – not a fun start to your summer break.

We asked experts for their top jet-lag-busting tips.

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 applied nutritionist Dr Ali Hill. 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."

When it comes to choosing from the drinks trolley mid-flight, she suggests sticking to plain water, as 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 – either 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 (hillarys.co.uk/static/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.

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.

"Also, try to preserve your pre-sleep habits and routines. These are important behavioural cues for sleep, so make sure you pack any items which support these behaviours, like 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.

6. Snack on cherries

Struggling to sleep in your hotel? Instead of ordering room service, try and find a fruit vendor. Montmorency tart cherries are one of the few natural sources of melatonin, the hormone responsible for the regulation of the body's internal clock and sleep-wake cycle.
