How to get over jet lag

28/02/202414 min read

Sick of jet lag ruining your holiday? It can happen to us all, but we'll share some ways to have a less tiresome trip.

Travelling abroad is all fun and games... until you’re wide awake in the early hours or dozing off in the day.

Jet lag happens to most of us when we switch time zones. It’s inconvenient, but thankfully it’s temporary and there are some ways we can help minimise it.

What’s jet lag?

Our bodies have their own internal clocks called circadian rhythms. They’re what help us feel tired at night and awake during the day.¹

Our circadian clock is “programmed” to our own time zone. So, when we travel, it can take some time to adjust.

Jet lag is the tiredness and other symptoms you might experience during this. But don’t worry, it shouldn’t last more than a few days.

It only happens when you travel between time zones. So, you won’t get jet lag on a journey travelling north or south that doesn’t change time zones, for example.

What does it feel like?

Jet lag symptoms can include:

Tiredness
Difficulty sleeping at night and waking up in the morning
Difficulty staying awake during the day
Poor concentration

You might also feel sick, have stomach problems, or feel generally “off” or anxious.² ³

What increases jet lag?

Some people get jetlagged more than others, and it’s not fully known why. But there are certain factors that can make it worse: ³

Your journey: The further the distance and the greater the difference in time zones, the worse your jet lag may be. The direction can also affect you: most people find that travelling east is harder than west.³
Sleep: Poor sleep in the days leading up to your journey can make you more likely to experience jet lag.³
Stress: Stress can disturb your sleep, which can make jet lag more difficult to handle.
Dehydration: It’s thought that dehydration may contribute to some symptoms of jet lag.¹
Alcohol and caffeine: These can affect other factors (like dehydration and sleep), making the effects of jet lag worse or making it more difficult to handle them. ³

How can you help get over it?

There isn’t a specific treatment for jet lag. You won’t usually need any medicine or to see your doctor.

Most people will feel better and be able to sleep normally after a few days, but there are a few extra ways you can help minimise the shock to your body clock:

Before you go

Get plenty of rest. Don’t set out sleep deprived in the hopes it’ll make you fall asleep on the plane!

Instead, gradually ease yourself in by going to bed and waking up an hour earlier or later (depending on your destination’s time zone) each day.

On your flight

Follow the times of your destination. For example, sleep if it’s night where you’re going, and eat your meals at your destination’s times if you can.
Drink lots of water – buy a large bottle at duty-free to make sure you have enough!
Keep your naps short. Power naps are okay, but try to keep them to 30 minutes or less to help your brain adjust. And save them for mornings: only nap at least eight hours before you plan to go to bed.³

Once you get there

Start trying to adjust to your new time zone immediately. That means sleeping at night! Even if you don’t feel tired, try to rest and do all the same things you’d do (like keeping lights low and screen time limited) at your usual bedtime.
Try to get outside during daylight hours. Light - and especially sunlight - has a strong influence on your circadian rhythm, so strategically timing your light exposure can help you adjust to your new routine.³
Avoid drinking too much caffeine and alcohol, as they can make jet lag worse.²

The final say

Jet lag can dampen the first day or two of a holiday. But it won’t last!

Fill up your water bottle and get some early nights in...
