1. What is altitude sickness? What are the symptoms of altitude sickness?

Altitude sickness is a natural physiological reaction after people reach a certain altitude, in order to adapt to the changes of air pressure difference, low oxygen content and dry air caused by altitude. When the altitude reaches about 2700 meters, altitude sickness will occur. Symptoms of altitude sickness generally include headache, shortness of breath, chest tightness, anorexia, low fever, dizziness and fatigue. Some people appear because of low oxygen content: purple lips and fingertips, lethargy, hyperactivity, insomnia and other different manifestations. Some people appear because of dry air: rough skin, chapped lips, bleeding nostrils or blood clots.

2. How to avoid or reduce altitude sickness?

Most people have mild or severe altitude sickness when they first arrive at the plateau. What kind of people generally have no rules to follow. The best way to avoid or reduce altitude sickness is to face it with a good attitude. Many reaction symptoms are caused by psychological effects or psychological effects. For example, people who are afraid of the plateau and lack the mental preparation and determination to overcome it will have more chances to have altitude sickness.

It is suggested that when you first arrive at the plateau, don't walk fast, let alone run or run, and don't do manual labor to avoid overeating and increase the burden on digestive organs. Don't drink and smoke, eat more foods rich in vitamins such as vegetables and fruits, drink plenty of water, keep warm and take fewer baths to avoid catching a cold and wasting energy. Don't take oxygen at first, try to adapt yourself, otherwise you may never be able to live without oxygen at the plateau.

You can take some drugs to relieve altitude sickness: Rhodiola sachalinensis (taken at least 10 days in advance), Gao Yuan 'an (taken after arriving in Tibet), American ginseng buccal tablets, Nuodikang capsules (very useful for relieving extreme fatigue), Baifuning (very useful for controlling headache caused by altitude sickness), American ginseng (very useful for relieving extreme fatigue), quick-acting Jiuxin pills (not allowed to take more), and so on. It is effective when altitude sickness symptoms appear). People with strong adaptability to altitude sickness can generally get rid of altitude sickness symptoms within 1-2 days, while those with weak adaptability need 3-7 days.

If you can adapt to the taste of butter tea, you can also drink more butter tea, which also has a certain effect on relieving altitude sickness.

3. What should I do if I have altitude sickness after I arrive in Tibet?

There are some hotels or towns with hospitals or health centers in Tibet. It is suggested to adapt to mild altitude sickness through self-regulation, and to see a doctor in severe cases. After altitude sickness, you should rest more, exercise less, insist on eating, and take some drugs to relieve altitude sickness.

Severe altitude sickness, such as edema, pulmonary edema, severe cold and other symptoms, it is recommended to go to the hospital for infusion, oxygen inhalation and other treatment, and leave the plateau as soon as possible. Lhasa is more convenient. There are flights in and out of Lhasa every day, and you can leave by plane. Generally, altitude sickness disappears without a trace as soon as it enters the plane or reaches the plain, and there is no sequelae.

4. What are the requirements for entering Tibet? Which patients should not enter Tibet? Do you need a physical examination? Do you need exercise?

In addition to maintaining a good attitude, there is no special requirement for a healthy body when entering Tibet. People with severe respiratory, tracheal, cardiac, cardiovascular and mental diseases are not allowed to enter Tibet. Therefore, patients with severe hypertension, heart disease, bronchitis, diabetes and colds are restricted from entering Tibet. It is recommended that you have a heart and lung examination before entering Tibet to confirm whether you have the above serious diseases. In addition, don't exercise deliberately before going to Tibet. If you keep exercising, you should stop half a month before going to Tibet, because the oxygen consumption increases after exercise, which increases the burden on your heart when you are in Tibet, but it is easy to cause altitude sickness.

5. Why can't I go to Tibet when I have a cold? How do you catch a cold in Tibet?

Cold patients can easily turn into other altitude sickness, especially pulmonary edema, which is a particularly dangerous altitude sickness. If not treated in time, their lives will be in danger. For cold patients, it is recommended that you cure your cold before you leave, and don't bring cold germs into Tibet.

Generally speaking, catching a cold in Tibet is not a big problem. Because you have certain adaptability and resistance at the plateau, your body has been basically adjusted and you can be treated in time. Moreover, doctors in Tibet are very experienced in treating colds. Take some cold medicine. Once you have cold symptoms, take some common cold medicine yourself. Symptoms will disappear after 1-2 days.

6. Is it convenient to take a bath in Tibet?

Cities of a certain scale in Tibet (such as Lhasa, Shigatse, Zhangmu Town, Gyangze, Zedang, Linzhi and Naqu) have bathing places, and 5 yuan is the only place to bathe. Generally speaking, the standard rooms of star-rated hotels have separate bathrooms with hot water for bathing, and many guest houses also have public baths, which regularly supply hot water for bathing. When you first arrive in Tibet, you should try to take fewer or no baths to avoid catching a cold or causing or aggravating altitude sickness due to excessive physical exertion. After a few days of arrival, it is generally no problem to take a bath after your body adapts to the plateau climate. Because the air in Tibet is dry and evaporates quickly, and the temperature is cold at night, most people don't particularly want to take a bath in Tibet, and they don't feel uncomfortable.

7. I heard that flying into Tibet is more powerful than landing on the Qinghai-Tibet Plateau?

That's true. However, flying into Tibet and entering Tibet by land have their own advantages and disadvantages. When you fly to Tibet, the altitude rises from several hundred meters to more than 3,000 meters. There is no gradual adaptation process from low to high, and altitude sickness is more likely to occur. Entering Tibet by land, the altitude gradually rises. Although it is beneficial to adapt to altitude sickness, the road conditions of most routes entering Tibet are not good. In Xinjiang and Qinghai-Tibet, there are several mountain passes at an altitude of 5000 meters along the way, and there are no hospitals and first aid facilities on the road. However, the road conditions in Yunnan, Tibet and Sichuan are extremely poor, and landslides and mudslides occur frequently in the rainy season, which is prone to danger. If you are not a self-help tour and have no outdoor travel experience, I suggest you go to Tibet by plane. If you love self-help travel, but have no experience in outdoor travel, I suggest you enter Tibet from the Qinghai-Tibet line for the first time, which is relatively safe.

8. Time is tight. How to choose tourist routes in Tibet?

For those who are pressed for time, flying back and forth is more suitable for you. You can choose Lhasa for four days, or Lhasa-Gyangze-Shigatse for six days, which is a golden tourist route in Tibet. If you are not a backpacker, you can contact the travel agency in advance and arrange your trip to Tibet. If you love self-help travel and have certain travel experience, you can make a travel plan by referring to books such as Self-help Travel to Tibet and Tibetan Cowhide Book, and send the plan to online outdoor forums in advance, such as Tianya Travel Edition www.tianyaclub.com and Wizard of Oz /html/Tibet/
