Why are passengers given chewing gum when flying?

When you're traveling by plane, the flight attendant always gives you chewing gum before the plane takes off, is this to add a sweet flavor to your trip? No, but to alleviate your discomfort during the flight.

We know that the density of atmospheric air varies, and the atmospheric pressure decreases with increasing altitude. Although the cabin of our large civil airliners is sealed, the pressure of the air in the cabin will still vary greatly during take-off, landing and navigation.

When the plane rises into the air, the air pressure in the cabin decreases, and the inner ear and the eustachian tube are closed with an atmospheric pressure of gas, resulting in a pressure difference between the inside and outside of the eardrum, so that the eardrum is subjected to pressure from the inner ear to the outer ear, making people feel dizzy, nausea, and even uncomfortable symptoms such as vomiting. At this time, as long as you open your mouth and make chewing and swallowing movements, the Eustachian tube will open and communicate with the air, so that the air pressure in the inner ear is the same as the air pressure in the cabin, so that the pressure difference on the eardrum disappears. In order to help you open your Eustachian tube and alleviate or even eliminate the discomfort caused by the change in air pressure, the flight attendant will give you chewing gum to help you get through this difficult time easily and sweetly.

From this example, students can know that when the air pressure in your surroundings changes drastically, it is one of the best ways to protect your ears by opening your mouth to keep the pressure of your inner and outer ears consistent.

To prevent the sound from deafening the ears, you can achieve this effect with your mouth open.

Chewing gum can be brought on board. After passing through the security check, you can take it on board after being checked by the security inspector. During take-off and landing, the ears will be uncomfortable due to the pressure at high altitudes, chew gum or eat to keep the air pressure inside and outside the eardrum in the mouth balanced.

Flight Procedure: To the airport. You have to pay attention to the time, because the airline rules that check-in closes 30 minutes before the flight, so you better be at the airport 1 hour before departure.

Check-in (i.e. change your boarding pass). Look at which counter your flight is in, there are display screens at the airport to tell you which flight is at which counter, find the corresponding counter, and hand your ID card to the airport check-in staff. If you have a large piece of baggage, check it in here, and baggage up to 20kg in economy class is free of charge.

Pay attention to the checked baggage do not contain prohibited items, after the check-in procedures, the check-in staff will return the boarding pass, baggage check, ID card to you. Go through security. When you go to the security check channel, there is a security counter at the entrance of the passage, you will hand over the boarding pass and ID card to the security inspector, and the security inspector will stamp the boarding pass if there is no problem.

Then go through the security gate, and you will have to pass through the X-ray security machine next to the security gate, and you will have to pass through the security gate yourself. If there is no problem with the security check, you will enter the departure hall. Terminal.

After passing through security, look at the gate on your boarding pass that indicates which gate your flight will be boarding in, and find the departure hall corresponding to the boarding gate, which is the number of boarding gates waiting for your flight. The location of each departure hall will be displayed on a display screen at the airport, and if you are not sure, you can ask the airport service staff.

Find your spot and sit down, buckle up and turn off your phone before you fly.

People who often do flying edge aircraft will find that many people will eat chewing gum when they take off and land, why do many people export chewing gum when the plane takes off and lands? In fact, this is caused by the change in air pressure in the cabin when the plane takes off and lands.

When the plane takes off and lands, the silver sparrow moves in the vertical direction, and the air pressure in the cabin changes.

The eardrum in the human ear isolates the air of the inner ear and the outer ear, and when the air pressure in the cabin changes, the air pressure of the outer ear changes, resulting in a pressure difference between the air inside and outside the eardrum, which can cause the tympanic membrane to rupture in severe cases.

Chewing gum. The swallowing action opens the eustachian tube that communicates with the throat, so that the air pressure in the inner ear is consistent with that of the cabin, so that the air pressure on both sides of the eardrum is the same, and it will not be swollen or dented under pressure.

During the take-off of the aircraft, the outside air pressure decreases rapidly, while the middle ear cavity still maintains normal pressure (relatively higher than the outside), causing the eardrum to bulge outwards and the pressure increases, at which time passengers will have a feeling of fullness in the ears. When swallowing, yawning, sneezing, chewing gum, or certain articulation movements, the movement of the surrounding muscles stretches the tube wall, causing the eustachian tube to open briefly, thereby adjusting the pressure in the middle ear cavity and making it balance with the outside world.

On some planes, candy such as chewing gum is specially prepared for passengers, and chewing and swallowing can also promote the opening of the eustachian tube. You can also try the nose puffing method: pinch your nose, close your mouth and blow your nose, if you feel as if there are two doors open in both ears, it means that the eustachian tube is open, and sometimes you need to do it several times to be effective.

Passengers with severe colds, nasal congestion and runny nose are advised to change to other means of transportation to avoid secretory otitis media caused by poor Eustachian tube function on the plane.
