Why do my lungs feel weird when I fly?

Air pressure is lower at higher altitudes, which means your body takes in less oxygen. Airlines “pressurize” the air in the cabin, but not to sea-level pressures, so there's still less oxygen getting to your body when you fly, which can make you feel drained or even short of breath.

Low air pressure during air travel also decreases the amount of oxygen in the air. This effect is modest and generally not noticeable for healthy travelers. For patients with significant lung disease, a small decrease in available oxygen can cause significant symptoms, especially with exercise.

Anyone travelling in an aircraft will have a drop in the amount of oxygen getting into their blood, although they are unlikely to feel any different. When you have a chronic lung condition this can make your chest symptoms worse. You may feel more breathless, your chest may feel tight.

Choose a seat in the middle of the plane. As the air circulates across the rows and not up and down the plane, some experts believe the worst air is in the front or the back of the plane. Stay well hydrated by drinking lots of fluids (water or fruit juice) and avoiding caffeine and alcohol, which will dehydrate you.

The cramped conditions and long periods of being less active on a flight can cause pain, stiffness or swelling of your legs. Being less active can lead to slow blood flow in your veins which increases your risk of developing a blood clot, known as deep vein thrombosis (DVT).

suggest that flying may cause a small pneumothorax to develop, which is then aggravated by further air pressure changes, most commonly the return flight. Thus, they recommend that patients are assessed for pneumothorax before making the return flight, although realistically this may not always be possible.

The main risk of flying commercially while suffering from a chest infection is acute respiratory distress. The oxygen level and atmospheric pressure are respectively lower and higher than we are used to in a pressurized cabin. Passengers with a chest infection are especially vulnerable to these changes.

The cabin can play havoc with your ears, sinuses, gut and sleep. gut problems – just accept that you're going to fart more. You can also feel more sleepy than usual. That's due to the body not being able to absorb as much oxygen from the cabin air at altitude than it would on the ground.

Jet lag is a temporary sleep disorder, but not temporary enough for many travelers. If you're flying from San Francisco to Rome for a 10-day trip, for example, it may take six to nine days to fully recover. That's because it can take up to a day for each time zone crossed for your body to adjust to the local time.

Prioritize rest. After a serious time-zone change, “I love to take a nap,” says Kristal Hicks of Top Tier Travel Group. Even if you're someone who can sleep on planes, a proper nap in a bed feels more restful, because you get to extend your body, Hicks says.

The hypoxic challenge test, also known as a fit to fly test, recreates the oxygen levels on an aeroplane and measures how your body responds. The test involves breathing in air containing less oxygen than normal and seeing how it affects you in a controlled environment.

If oxygen deficiency continues over a long enough period of time, it can cause unconsciousness, permanent brain damage or even death. So, in order to keep everyone maintained with enough oxygen, the masks fall down and provide a personal flow.

MORE DETAILS

Oxygen production cannot be shut off once a mask is pulled, and oxygen production typically lasts at least 15 minutes, sufficient for the plane to descend to a safe altitude for breathing without supplemental oxygen.

“There's a plethora of evidence that you go into a relative state of hypoxia [oxygen deficiency] when you're in flight,” said Quigley. The affects, she says, may not be realized by passengers. “One person might feel weepy, another sleepy – hypoxia affects people in different ways.

Flying is a stressful experience
Air travel is stressful even under the best of circumstances, and a large part of that comes from having to relinquish control, which happens long before you reach the plane seat. Upon entering an airport, you are sifted through a regimented, mandatory, and inconvenient set of steps.
