Why don t people have altitude sickness on airplanes?

Altitude sickness is mainly due to the high altitude "above 3000 meters", the air pressure increases, the human body, especially in the skull, like a balloon that has been inflated, the pressure is also increasing, compressing the cranial nerves and some internal organs, and causing human discomfort, and the normal flight cabin after pressurization, the air pressure is equivalent to more than 2,000 meters, which is what people can bear.

Altitude sickness is mainly due to the high altitude "above 3000 meters", the air pressure increases, especially in the skull, like a balloon that has been inflated, and the pressure is also increasing, compressing the cranial nerves and some internal organs, and causing discomfort to the human body, and the normal flight cabin after pressurization, the air pressure is equivalent to more than 2,000 meters at most, which is what people can bear.

Altitude sickness is mainly a manifestation of acute pathological changes such as hypoxia and decreased oxygen concentration. At higher altitudes (> 3000 m), the partial pressure of oxygen decreases, resulting in a hypoxic environment. Prone to altitude sickness.

When the aircraft is at low altitude (less than 2-3km), the pressure difference between the inside and outside is basically the same as that on the ground. After high altitude, the cabin is pressurized, and the control is consistent with the ground. So there will be no altitude sickness.

In fact, there will be discomfort, when the plane descends, the pressure in the cockpit increases with the increase of external air pressure, and the pressure in the human ear changes slowly, and some people will have tinnitus, earache and other phenomena.

Because the aircraft is a fully enclosed cabin, during takeoff, the pressurization device in the aircraft will be inflated to increase the atmospheric pressure in the cabin, and the aircraft will reach the height limit of the normal air pressure that the human body can withstand in the climbing process, the height is 3000 meters, and then, the pressurization device will make up for and adjust the pressure environment faced by the aircraft when it rises in the cabin, so that the whole cabin has been maintained in the normal air pressure within the range that the human body can bear.

So the reaction is small rather than none.

Because the aircraft is completely sealed and can be supplemented with oxygen, after the cabin is pressurized, the air pressure in the cabin is equivalent to about 2,500 meters during the cruise, and people will not have altitude sickness at this altitude.

After the cabin of the aircraft is pressurized, the air pressure in the cabin is equivalent to about 2,500 meters during the cruise, and people will not have altitude sickness at this altitude.

There is oxygen supply in the cabin. It can meet the oxygen supply needs of a person without hypoxia.

Why doesn't I get altitude sickness when flying?

You can fly after altitude sickness.

Altitude sickness is caused by the lack of oxygen in the human body when people who usually live on the plains or seashores enter high-altitude areas, and the air pressure is higher in places with relatively low terrain such as plains and seashores, but if you come to the plateau, it is equivalent to being exposed to a low-pressure and low-oxygen environment, and the body's various functions are not adapted to the low-pressure environment, and altitude sickness will occur.

Although the aircraft is at an altitude of 10,000 meters when cruising, the cabin of the aircraft is closed to the outside of the aircraft, the air pressure in the cabin basically maintains an atmospheric pressure, the cabin has a pressurization and oxygen system, and the internal environment of the cabin is about 1,000 to 2,000 meters above sea level, and the oxygen content is much richer than that in the plateau area, so normal people will never have altitude sickness on the plane.

Therefore, it is possible to fly after altitude sickness.

Altitude sickness is a symptom of lack of oxygen dissipation, and people's psychology has a certain relationship, people will appear in high places will have excessive tension Hu Zi people, into the altitude of more than 3,000 meters will immediately feel nausea, uncomfortable, dizziness, head swelling and other discomfort, which is not directly related to taking a plane.

Altitude sickness is generally not caused by airplane, because there will be pressurization and oxygen supply in the cabin of the plane, altitude sickness is when people are at an altitude of more than 3000 meters, the air encountered is more pressure than on land, and various discomforts will occur.

What should I do if I encounter a high reaction on an airplane?

1. It is best to do a good job of prevention before taking the plane, because everyone's physique is different, and there is no way to ** whether they will have symptoms of altitude sickness, so they should prepare in advance, and they should do a good job of physical examination in advance, and if the body is not suitable, do not take the plane.

2. You can carry some drugs to prevent altitude sickness, commonly used are sedatives, diuretics, vitamins, adrenal corticosteroids, or you can bring some vitamin-rich fruits, which can be eaten at any time and can be supplemented in time.

3. The general symptoms of altitude sickness include dizziness, headache, decreased appetite, insomnia, weakness, irregular heartbeat and other symptoms. If such a situation occurs, the flight attendant on the aircraft should be notified in time and rescue measures should be taken in time.

4. People with poor physique, or heart disease, it is best not to take a plane, if you have to take a plane, you must be accompanied by someone to avoid a situation, someone will find out in time, especially some elderly people, you need to take a plane accompanied by children, which will be safer.

This is because although the aircraft flies high, the cabin of the aircraft is closed to the outside of the aircraft, the cabin is in a closed pressurized state, and there will be an oxygen supply. The atmospheric pressure in the cabin is basically the same as the air pressure that people usually sit in, so people will not have severe altitude sickness in the plane because the air pressure becomes low.

The incidence of altitude sickness is related to the speed of climbing, altitude, length of residence, and physical fitness. Generally speaking, when plain people quickly enter the plateau above 3000m above sea level, 50% and 75% of people have altitude sickness, but the symptoms gradually disappear after 3 to 10 days of habit. The incidence of this disease is lower in the elderly than in young people, and in women than in men; The incidence of altitude sickness was positively correlated with the body mass index of men and not with the body mass index of women, indicating that obese men were more susceptible.

When the passenger plane is flying at high altitude, the cabin is sealed, and the air pressure and oxygen content are basically the same as those on the ground, so there will be no altitude sickness. If you go to a place at a high altitude, it is easy to get altitude sickness. The various discomforts caused by exposure to the low-pressure and hypoxic environment of the plateau above 3,000 meters above sea level are common diseases unique to the plateau area.

Common symptoms include headache, insomnia, loss of appetite, tiredness, difficulty breathing, etc. You can take some drugs to relieve altitude sickness: Rhodiola rosea, Omo blue tablets, glucose solution and other drugs to relieve altitude sickness have a certain effect.

Why doesn't I get altitude sickness when flying?

1. There will be no altitude sickness when taking a plane, because the plane will have pressurization and oxygen supply in the cabin during normal flight, so it will not produce a high reaction of mammost.

2. Altitude sickness is mainly due to the high altitude "above 3000 meters", the air pressure increases, and the pressure in the human body, especially in the skull, is like a balloon that has been inflated, and the pressure is also increasing, compressing the cranial nerves and some internal organs, and causing discomfort to the human body, and in the normal flight cabin after the bridge is pressurized, the air pressure is equivalent to more than 2,000 meters at most, which is what people can bear.
