Being one of the main airports in Vietnam, Noi Bai welcomes thousands of visitors to come and go everyday. Although the information about airline services is quite clear and there are many other of them are spreaded all over the internet. But there are truths about the flight that no Airline has revealed to its passengers.

Sensational facts about the filght

1. The affection of the atmospheric pressure

Firstly, the way your body operating while flying in an airplane has nothing in common with moving on the ground in a car - just a look outside the window then you will be certain of that. However, your sense is not the only thing can tell the difference between sea level and cruising altitude but your organs can too. And the atmospheric pressure is a main factor that credited for all the changes that happen in your body while flying.

Atmospheric pressure, or air pressure, is the force exerted on a surface by the air around it. As you climb in altitude, atmospheric pressure decreases, which can affect your body in many different ways.

An airplane’s typical cruising altitude is somewhere between 36,000 and 40,000 feet. For people inside the plane to survive a high altitude like this, the interior of the plane is pressurized by conditioned air being pumped through the cabin. This simulates an environment that feels more like 6,000 to 8,000 feet — an altitude similar to what you might experience in mountainous areas.

The high altitude can cause a few symptoms and side effects. For one, your blood absorbs less oxygen at cruising altitude — this can make you feel sleepy or give you a headache.

In addition, humidity levels at cruising altitude can be as low as 4 percent, which can in turn cause dehydration and dry skin, and, when combined with cabin pressure, it can even numb some of your tastebuds.

Cabin pressure can also cause bloating and stomach pains, as the gas in your intestines expands as the plane climbs in altitude and cabin pressure drops.

One often-discussed potential ailment caused by air travel is deep vein thrombosis. DVT occurs when blood clots form in deep veins within the body, typically in the legs. They can develop if you stay seated for too long.

2. What is the solution for the changes of the atmospheric pressure

Even there are nothing much you can do to remove the affection, but to stay healthy and comfortable or at least to get better while flying, here is some methods that you can try out:

• Keep your body in movement as frequent as you can. Get up and move around whenever it is allowed and when your body is not ok.
• Stay hydrated by drink plenty of water, alcoho beverages are not recommended.
• Use saline nasal spray to combat dry air.
• Use a moisturizer to hydrate your skin.

Out of all the sensational facts, air travel is still the safest form of travel, and if we provide ourself enough knowledge about what is happening to our body during the flight, it can be the most comfortable form of travel as well.
