These 6 things that happen to your body when flying  


Ever wondered what happens to your body when you fly? Why do your ears pop on an airplane? Why do you always need so many drinks? If you are concerned about the health effects of flying, read this post to revealsome of the strange sensations you might experience on your flight:


When an aircraft is in the skies, the humidity inside the cabin is only about 20 per cent – that’s a big drop from the usual comfort level of 50-60 per cent. When the humidity level is low, it means that water is evaporated from your body, which makes you feel thirsty.

Dehydration isn’t the only problem when you’re surrounded by dry air. Cilia – little hairs in your nose and throat – aren’t up to their usual job in these conditions as they can’t catch airborne irritants. This means you are lots more likely to catch nasty bugs from fellow passengers.

To avoidfeeling dehydrated, ensure you have regular drinks on board but avoid alcohol or caffeine as these can make you thirstier.

Numb taste buds

Why does the food taste so poor on a plane? Even your favourite roast chicken dinner just seems to lack flavour.That’s because the pressurized air in the cabin takes a hold of your senses. Suddenly your ability to taste sweet or salty things drops by a third, and the cabin air affects your ability to pick up scents.

But whatever you pick to eat, make sure you stay well-hydrated to stop your taste buds from drying out.

Bad circulation

Problems with circulation, particularly in your legs, are caused by the low humidity and high pressure in the airplane. Sitting in the same position for ages may cause your legs to swell up and feel heavy. Deep vein thrombosis – the formation of a blood clot within a deep vein –isone of the conditions you can get from travelling.

Compression socks are a good idea to stop this feeling, as they are designed to enhance your blood flow, which in turn, reduces the risk of deep vein thrombosis.


One reason why you may feel drowsy on a plane, is due to the high cabin pressure. The higher the plane goes, the less oxygen you breathe in. Because your body is not used to that kind of environment, you will get tired much more quickly and want to have a snooze.

If you’re worried about falling sleeping on the plane, read a book or watch a movie.


Airplanes and tummies don’t really get on.The food we eat causes trouble for our tums as we are constantly sat in the same position for long spells of time. Our cells get so dry and become less able to absorb the nutrients we need or get rid of waste water.

The result is bloating and your belly can feel upset if it gets swollen. You may feel like you need to pass wind. If this is the case, just do it – everyone else is! If you try to hold in your trumps, it could cause you to feel more uncomfortable. Probiotic drinks are great for preventing this feeling, if taken before your flight.

Popped ears

Why do your ears pop on an airplane? When pressure on either side of your eardrum becomes unequal, it can cause pain in your ears when a plane descends.

You sometimes hear popping when the plane is soaring into the skies because the air has nowhere to escape in the inner ear.

Some people who are prone to this problem can take decongestants during the flight. You can also suck a sweet, click your jaw or have a drink.

As you are now aware of the health effects on flying and what happens to your body when you fly, you can be well-prepared for your next flight. And don’t let these strange sensations ruin your holiday, like a delayed flight can. If you need help, you can contact experts to begin a flight delay compensation claim.
