Jet Lag

Planning your summer getaway? Here’s how to avoid jet lag

Nearly 93% of travellers experience jet lag at some point, so here’s how to stop it ruining your holiday

For many of us, the arrival of sunshine immediately inspires us to book that all important summer holiday. It’s hard to resist the draw of a couple of weeks stretched out beneath the blazing sun, but for too many of us jet lag can put a serious dampener on our getaway.

Luckily, it is possible to avoid jet lag and enjoy your holiday from the moment you step off the plane. The first step to beating jet lag is understanding it, which is why we’ve put together this handy guide to answer all your questions.

What is jet lag?

Jet lag occurs when your normal sleep pattern is disturbed after a long flight. Due to a shift in time zones, your body clock — or circadian rhythm — has to adjust to a new schedule, which can lead to sleep deprivation and exhaustion.

Who gets jet lag?

Jet lag can affect anyone travelling across time zones, and the only fluctuations in severity are a result of personal differences. For example, people who stick to rigid routines at home are often worse affected by jet lag than people with more fluid schedules. Young children are also often less affected by changing time zones.

The main factor which determines the extent of jet lag is the distance of travel. The more time zones you travel across, the more severe your jet lag is likely to be. What’s more, travelling west to east usually results in worse jet lag than travelling east to west, reflecting the greater difficulty of advancing your body clock compared to delaying it.

What causes jet lag?

The dominant cause of jet lag is travelling across time zones, which alters your circadian rhythm and makes it difficult to adjust to a new schedule of sleeping and waking. However, other factors which can impact on the severity of your jet lag include:

Your pre-flight condition, particularly tiredness, anxiety, stress or being hungover

High altitude and increased cabin pressure, which can lead to swelling and tiredness

Alcohol consumption, as the impact alcohol has on the body increases two-fold when you’re flying

Dehydration, which can be caused by alcohol but also through lack of water and a reliance on strong coffee

Lack of exercise, which is why passengers should stretch, get up and move regularly throughout their flight

How do you know if you have jet lag?

- The main symptoms of jet lag include:

- Difficulty waking up in the morning and sleeping at night

- Tiredness and exhaustion

- Poor sleep quality

- Finding it hard to stay awake throughout the day

- Lack of concentration

- Memory problems

- Indigestion, constipation and diarrhoea

How do you prevent jet lag?

Symptoms of jet lag usually improve on their own after a few days as your body clock adjusts to its new time zone. However, there are steps you can take to avoid severe jet lag.

Before you travel: make sure you get plenty of rest, following good sleep practices before going to bed. Try changing your routine gradually, going to bed and waking up an hour or two earlier or later than you normally would (in accordance with your new destination). You should also avoid alcohol, caffeinated drinks and large meals before bed.

During your flight: drink plenty of water to stay hydrated, and stay active by stretching and walking regularly. If your flight takes place during normal sleeping hours (in line with your destination) then try to sleep.

After you arrive: change your sleep schedule to fit your new location as quickly as possible, and set an alarm to avoid oversleeping. Go outside during the day, as natural light will help your body clock adjust. Try to stay awake until a reasonable bedtime for your new location without relying on naps to perk you up.

You can also use effective medication to avoid jet lag. Circadin is a prescription medication which acts as a short-term treatment for insomnia. When taken whole one to two hours before bed, Circadin provides melatonin: the body’s natural sleep hormone, making sleep easier. This can help treat symptoms of jet lag.

Get the most out of your summer holiday by making sure you arrive as happy and healthy as possible

Everybody looks forward to their summer holiday, but few of us are as excited for the plane journey beforehand. Whether you are afraid of flying or just hate cramped, hot conditions, many in-flight experiences leave much to be desired.

Here are a few of our top tips on making international travel as comfortable as possible.

What can you do aboard your flight?

Even the most confident flyer wants to know they’re doing everything they can to stay as safe as possible whilst en route to their holiday destination. Thankfully, there are some simple precautions you can take.

Dress comfortably

Comfort is key when you’re on a plane, especially if you’re on a long haul flight and have restricted movement for hours at a time. Opt for loose, light layers that let your body breathe, and be sure to bring a jumper or cardigan to put on if you feel cold at any point.

Blood clots are one of many people’s biggest fears regarding a long haul flight, so it’s important to prevent restriction on your body where you can, including through your clothing. You may also have seen special compression socks available in airports or travel stores – these are designed to safeguard against deep vein thrombosis and can be a welcome addition to hand luggage.

Listen to the pre-flight briefing

Some people see the safety demonstration at the start of a flight as a chance to switch off, but the information included in this briefing could be life saving if an emergency does occur on your flight.

Be sure to listen carefully to the information being given, paying particular attention to where your nearest exit is and how to put your oxygen mask on correctly.

Get to know your seatbelt

Aeroplane seatbelts are notoriously fiddly, so make sure you’re familiar with the logistics of fastening and unfastening your belt with ease. You should also be paying attention to the seatbelt light above your head, as this will inform you when you need to be in your seat with your seatbelt fastened.

Relax

One of the worst things you can do on a flight is get stressed. Stress increases your levels of cortisol, which boosts your adrenaline and makes you feel restless. This isn’t what you want when you’re spending the next few hours stuck in the same environment. Take your mind off your flight, bring a book or try to sleep, and let your body and your mind relax.

Looking after your health: what is altitude sickness?

One of the biggest risks to your health when flying is altitude sickness, which is exactly as it sounds: feelings of nausea and discomfort when high in the air.

Why do you feel sick when flying?

Altitude sickness is a response to a higher altitude and lower air pressure, which can have a negative effect on the body. This combination means that the air you breathe has less oxygen per breath. It also causes the air to be dryer and water to evaporate faster.

Aside from the obvious sickness, symptoms of altitude sickness can include tiredness, backache, headache, muscle cramp and light-headedness. Certain individuals may be more susceptible to the condition than others, such as people with existing health conditions like heart disease.

What can you do to avoid altitude sickness?

Hydration is key to tackling altitude sickness, as a lack of hydration is a key component of the sickness itself. Drink plenty of water and be sure to avoid caffeine and alcohol.

You should also try to move around aboard your flight when you can. Doing gentle stretches whilst sitting and taking short walks along the aisle can help reduce your risk of blood clots and deep vein thrombosis (DVT).

Finally, you should consider medication to help treat your altitude sickness. Acetazolamide is an effective treatment which reduces the amount of excess fluid in your head and lungs, making it easier to breathe. This medication is available from Express Pharmacy.

Before you set off this summer, make sure you know how to keep you and your family safe when you’re up in the air. For more health queries and concerns, you can contact Express Pharmacy today via our discreet Live Chat tool.

If you have ever flown long distance, the chances are that you will have experienced jet lag to some degree. Jet lag occurs when our bodies have to rapidly adjust to a new day and night schedule, throwing our circadian rhythms out of balance and leading to feelings of exhaustion, restlessness, nausea and dizziness. It’s not pleasant, and can put a dampener on the start of your holiday, so what can you do to try and lessen your symptoms?

Unfortunately, there is no outright cure for jet lag. But there are several things you can do to ease the problem and stop a change in time zone from ruining your break.

Moving on the plane makes a difference

When on a long haul flight, your best bet is to sleep as much as you can. However, many of us find it difficult to sleep effectively on uncomfortable plane seats.

So if you’re not sleeping, the next best thing to do is get up and move around as regularly as possible. Moving around the plane — or even just doing a few simple stretches every now and then — will help keep you mentally and physically active and prevent blood clots by keeping your blood pumping. It will also help you sleep better later on, as you’ll feel less restless.

Natural light has an impact

Natural light plays a big part in your circadian rhythm. Studies have shown that bathing yourself is natural light is one of the most effective ways of combating jet lag as it encourages our release of serotonin — the hormone which provides us with energy. Once you arrive at your destination, take a short walk and indulge in a little sunlight before attempting to sleep. This will help your body get used to its new schedule.

Severity can depend on the direction you fly

The seriousness of your jet lag often changes depending in which direction you fly. Travelling eastward makes jet lag worse, because travelling in this direction causes you to lose hours in your day, making it harder for your body to catch up with itself. It’s much more difficult to adjust to losing hours than gaining them, so if you’re travelling east this summer take extra care with your sleep health.

Dehydration plays a part

Dehydration leads to many of the same symptoms as jet lag, such as fatigue, nausea, headaches and dizziness. This means that being both dehydrated and jet lagged can make your condition even worse.

Regular hits of cold glasses of water are a good way of keeping unnecessary symptoms at bay, and will also help you feel more alert. Not to mention, all those extra bathroom visits will force you to be more active on your flight!

Drinking does more harm than good

There is a myth that having a few drinks on a long haul flight will help you avoid symptoms of jet lag. Unfortunately, this is not true. In fact, the opposite is typically the case. Alcohol might help you fall asleep faster, but it’s also guaranteed to lower the quality of the sleep you are getting. This will make you feel more tired and more irritable, as well as increasing your risk of dehydration and therefore extra, unwanted symptoms.

Caffeine can help beat it

A cup of coffee can actually improve your symptoms of jet lag, but only when used in the right circumstances.

If you’re travelling west then a cup of coffee at the right point in your journey may help you stay awake for longer by providing you with an extra burst of energy.

However, drinking coffee when you’ve lost time could prove disastrous as you should be aiming to relax your body in preparation for sleep. Travelling east? Avoid caffeine.

Use Circadin

At Express Pharmacy, we stock Circadin, a prescription only medication containing Melatonin. Melatonin is a naturally occurring hormone in the body and is used to help treat the symptoms of jet lag. Find out more here.

Whether you are travelling abroad for work or escaping it all for a relaxing week away, feeling healthy and fresh on arrival, is always a bonus. Unfortunately those trips that involve crossing multiple time zones can wreak havoc with our internal body clock – commonly known as jet lag.

Jet lag goes far beyond simple fatigue. In fact, there are a whole range of symptoms that can occur when our bodies struggle to adapt to a new light-dark schedule. Along with the common symptoms of disturbed sleep and lethargy, sufferers may experience a change in appetite, digestion, blood pressure and body temperature. And while jet lag is inevitable when you are crossing 7 or more time zones, there are a few easy tips that can greatly reduce its effects.

Here we share five easy tips to make sure jet lag does not affect your continental trip:

Say no to the drinks trolley

As tempting as it maybe to order a few glasses of wine or bottles of beer during a flight, it is something that definitely should be avoided if you are travelling long haul. Drinking alcohol may feel like a nice way to relax and may even help you nap. But the resulting dehydration will do you know favours and probably give you a nasty headache. It’s important to be aware that while alcohol can make you feel drowsy, it does not result in quality, restful sleep.

One of the most effective methods of fighting jet lag is to stay hydrated before and during your flight. This means watching your alcohol intake the week before flying to avoid dehydration.

Stay active:

A little bit of exercise before you fly is a great way to beat in-flight lethargy and you don’t necessarily need to commit to a full workout, either. Just make smart choices at the airport, instead of taking the escalators and travelators, take the stairs or carry out some light stretching before you set off for the airport.

Remember, you are going to be sat in a small space, for many hours so it is important to maintain blood circulation. Getting up and taking a walk whenever possible can help to keep your blood moving and prevent any numbness. Even whilst seated, stretching out your legs and wiggling your toes can help to keep your body in a better condition. It will also help to reduce the likelihood of deep vein thrombosis.

Time it right:

It is important to psychologically adjust to your new time zone as soon as possible so you are mentally prepared for the alteration to your sleep–wake cycle. Changing your eating schedule to match your new time zone is a great place to start. If you land in the morning, make sure you eat breakfast even if you are not hungry to get you settled sooner.

Tackle it with tech:

Adjusting your sleep schedule the week before you travel can be a tricky business, but thankfully there are plenty of apps out there that help you create and stick to a helpful sleeping plan before you go.

Choose your medication wisely:

It maybe a popular tactic, but taking sleeping pills on-flight should be avoided as they will only add to your drowsiness on arrival. However, there are other forms of medication that are better suited to tackling jet lag. Circadin is currently the only medication available with the active ingredient Melatonin – the hormone that regulates the sleep–wake cycle.

For most of us jet lag is simply an inconvenience that goes hand-in-hand with long haul flights, and for holiday goers the prospect of getting over the symptoms of jet lag on an exotic beach is enough to overlook the difficulties faced. However, for frequent flyers, jet lag is a very real and debilitating issue.

While our bodies and minds are simply not designed to cope with dramatic changes in time zones, there are a number of steps that you can take to alleviate and treat the symptoms of jet lag.

What exactly is jet lag?

Jet lag is experienced by individuals of all ages as they travel from one time zone to another. This journey essentially affects your body’s internal clock – the circadian rhythm – causing a wide range of unpleasant symptoms. The circadian rhythm is a 24-hour cycle of physiological processes that are initiated primarily by sunlight and temperature.

When jet lag is experienced these rhythms need time to adjust, particularly when it comes to your sleep-wake cycle.

What are the symptoms of jet lag?

There are a variety of symptoms associated with jet lag, and these tend to vary from person to person. The most common symptom is a disturbed sleep pattern, a side effect that will adjust as time goes by. Jet lag can also affect your digestive state causing problems like indigestion, constipation and diarrhoea.

Other jet lag symptoms include:

• Vomiting
• Diminished appetite
• Headaches
• Muscle tenderness
• Feeling unwell
• Decreased energy levels
• Sweating
• Irregular menstruation for women

In addition to affecting the body physically, it can also have implications for your state of mind. These symptoms can include increased levels of anxiety, irritation or confusion, diminished concentration and short-term memory issues.

Do jet lag symptoms worsen the further you travel?

Just how severe your jet lag is depends on how many time zones you have travelled across. Those making their way across one or two time zones should experience little or even no jet lag. In fact, the majority of travellers don’t suffer significant jet lag until they cross three time zones or more in a flight. It is possible to experience symptoms of jet lag for up to six days if you have travelled across more than nine time zones.

Jet lag symptoms have been found to be more severe in people travelling in easterly directions, rather than on westerly flights.

How can jet lag be prevented and treated?

Unfortunately, there is no straightforward cure to jet lag. However, there are a number of steps that can be taken to reduce the impact on your mind and body. Adapting your sleep routine three to four days before your flight is an excellent way to make recovering from jet lag even faster, simply adjust your bed time by an hour in accordance with the time zone of your destination.

Numerous strategies can be utilised during your flight to reduce symptoms upon arrival. Stay well hydrated, avoid caffeine and alcohol, sleep in short bursts and try to stay as active as possible with regular walks and stretching. Changing the time on your watch to the time at your destination will also help you adjust more quickly. Once you arrive try not to nap as soon as you get to your accommodation, instead opt for an outdoor excursion – exposure to natural light works wonders – and get started with your new routine sooner rather than later.

Here at Express Pharmacy, we stock effective jet lag treatment Circadin, a medication that contains melatonin. Melatonin is a hormone that is released in the body at night-time each day. It is an important part of every individual’s chemical make-up and helps to shape the sleep–wake cycle.

The melatonin contained within Circadin, helps to adapt you feeling of sleepiness to help you adapt your sleep pattern to the new time zone in which you find yourself. By helping you to achieve good quality natural sleep, your body and mind will more swiftly adapt to the new environment and allow you to feel refreshed and full of energy once more.
