What is altitude sickness? What kind of people don t have altitude sickness? What does it mean to no

Personally, I think it varies from person to person

Altitude sickness usually occurs in the following conditions.

1.By geography.

People living in coastal and inland plains, because of the low altitude of coastal and inland areas, usually have sufficient oxygen, and when they first arrive at the plateau, they are prone to altitude sickness due to the relatively large oxygen difference.

2.Divided by physical characteristics.

People who are obese are generally obese consume a lot of oxygen, and most people have poor microcirculation and poor oxygen supply, so they are prone to altitude sickness.

3.By age.

Older people are prone to altitude sickness, people over 40 years old, organ function begins to fail, biological oxidative metabolism function begins to decline, but oxygen consumption does increase year by year, and the energy produced gradually decreases. So it is easy to get altitude sickness.

4.People with high blood pressure, high blood sugar, high blood lipids, cardiovascular and cerebrovascular diseases, hypotension, and hypoglycemia are prone to altitude sickness. Because hypoxic injury first leads to erythrocytosis, elevated blood pressure and blood sugar affect blood oxygen diffusion and aggravate hypoxia.

Altitude sickness, symptoms include headache, chest tightness, palpitation, loss of appetite, shortness of breath, palpitations, nausea and vomiting, cyanosis of the lips, insomnia, dreaminess, increased blood pressure, etc. (unsteady sleep, anorexia, dizziness, fatigue, purple lips and fingertips, drowsiness but unable to sleep, transient cerebral ischemia due to short-term coma).

There are basically the following groups of people who are prone to altitude sickness:

1.Obese people are generally more likely to develop MTB than thinner people due to higher oxygen consumption.

2.People who usually have low blood pressure are prone to altitude sickness.

3.People with low blood sugar are prone to altitude sickness.

4.Older people are more susceptible to altitude sickness.

5.Sub-healthy people are more likely to have altitude sickness.

At present, the relatively good medicine for preventing altitude sickness is Youyi Vitality Travel Tablets.

The severity of altitude sickness varies from person to person, generally speaking, weak people may not react much, and strong people may not be unresponsive. Thin people are better than fat people, women are better than men, short people are better than tall people, and young people are better than old people. Altitude sickness can cause the following symptoms:

Headache, palpitation, shortness of breath, chest tightness, pounding heartbeat, loss of appetite. Low-grade fever, high fever, vomiting, confusion, hallucinations. When you go to the plateau, you can carry anti-anti-anti-anti

In severe cases, oxygen or medical attention may be required.

Those who have a bad constitution are already sick.

Altitude sickness is acute altitude sickness, which is a natural physiological reaction produced by the body to adapt to the changes in air pressure difference, low oxygen content, and dry air caused by altitude after reaching a certain altitude, and the altitude generally reaches about 2700 meters. The symptoms of altitude sickness are generally manifested as: headache, shortness of breath, chest tightness, anorexia, slight fever, dizziness, fatigue, etc.

Some people have different manifestations due to low oxygen content: purple lips and fingertips, drowsiness, hyperactivity, and inability to sleep. Some people appear due to dry air:

**Roughness, chapped lips, bleeding or blood clots in the nostrils, etc.

1. People with cardiovascular disease. Patients with coronary heart disease, rheumatic heart disease, congenital heart disease, myocarditis, history of cardiomyopathy, and heart failure are included.

2. Patients with high blood pressure. Because the high-altitude environment causes blood vessels to constrict, making the patient's blood pressure higher.

3. People with poor lung function. For example, patients with chronic bronchitis, emphysema, pulmonary heart disease, tuberculosis, and pulmonary interstitial fibrosis will aggravate the symptoms of such patients because of the thin air, which makes the oxygen content in the blood vessels lower.

Fourth, cold patients. Because the body is in a state of stress when people have a cold, the bronchi and respiratory tract are also in an unhealthy state, and if you enter the Qinghai-Tibet Plateau at this time, the condition will be aggravated.

5. Patients with hyperlipidemia. The oxygen-thin plateau environment can promote the increase of erythrocytes in the body, so the blood of patients with hyperlipidemia will become more viscous, resulting in hypoxia.

The reason for the formation of mountain sickness is that the higher the altitude, the thinner the air, the lower the air pressure, so the oxygen pressure required by the human body is also reduced, but the oxygen content required by the human body remains the same, in order to maintain the oxygen content required by the human body in the blood, the content of red blood cells must be increased, but it takes several days for the human body to automatically increase the content of red blood cells.

Therefore, when entering the mountainous area, the human body will not have time to adapt to the sudden increase in altitude, and the lack of oxygen in the body will occur, the higher the altitude, the shorter the transition time, the more intense the reaction, this physiological reaction is generally called [mountain sickness].

Lhasa is 3,650 meters above sea level, and it is easy to suffer from altitude sickness. However, altitude sickness varies from person to person, and altitude sickness focuses on resistance, and not everyone will have it. However, taking an airplane is more likely to occur than self-driving and taking a train, after all, taking a train is not a one-time arrival, and the gradual increase in altitude on the train can allow the human body to have a relatively slow adaptation process.

However, this does not mean that the train entering Lhasa will not cause a high reaction, because it mainly depends on the individual's physique. Another point is not to take a bath and wash your hair, do not drink, do not exercise vigorously within two or three days after arriving in Lhasa, this is what the tour guide who took me to me before focused on and said, because the air in the plateau area is thin, the oxygen content is low, and the lack of oxygen supply will lead to headache, dizziness, and even vomiting, and in severe cases, pulmonary edema will occur, and bathing, drinking, and exercise will accelerate blood circulation, which will lead to accelerated breathing, and the plateau is hypoxic, so it will be easy to have altitude sickness. Many people are in the plateau area, including me, altitude sickness does not appear immediately, many of them have high reaction that night, and some are the second or third day, so generally pay attention to the first three days and do not do behaviors that will cause high reaction.

Therefore, it is recommended to prepare sufficient materials when you are ready to go, such as appropriate thick clothes, because the temperature difference between day and night is relatively large; There are also some anti-anti-anti-anti-anti-anti-anti

Everyone's physique is different, and the adaptability to the plateau is different. Altitude sickness is common to everyone, it's just a little bigger.

The mentality of going to the plateau should also be correct, and a good attitude is correct.

Before going to the plateau, you can take some anti-altitude sickness Rhodiola plateau Ann, which can effectively reduce the chance of occurrence.

For people with strong altitude adaptability, the symptoms of altitude sickness can be eliminated within 1-2 days, and those with weak adaptability need 3-7 days. You can take some medicines to relieve altitude sickness: Rhodiola rosea, Omo Blue Tablets, Gaoyuanan and so on.
