Beautiful Tibet is desirable. I will travel to Tibet in a few days, but I am worried about altitude sickness. How to prevent altitude sickness?

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, do manual labor, and don't overeat, so as not to increase the burden on digestive organs, don't drink and smoke, eat more foods rich in vitamins such as vegetables and fruits, drink more 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.

The severity of altitude sickness varies from person to person Generally speaking, young people are better than middle-aged and elderly people, children and teenagers. For people who live in low-altitude areas (such as the eastern coastal areas) for a long time, when they go to the plateau for the first time, there will be slight precursors of altitude sickness above 2000 meters, such as easy hunger, headache and insomnia. At this time, they need to be careful not to catch a cold. When the altitude exceeds 3000 meters, many people will have obvious altitude sickness, such as panting and purple lips. People who have been engaged in physical exercise for a long time and are healthy can persist to about 4400 meters. However, to be on the safe side, if it is the first time to go to the plateau and the destination is above 3000 meters, it is recommended to make some preparations in advance. If you have enough time, I suggest that you don't rush at altitude, rest for one to three days at about 3500 meters, and then enter a higher altitude area after adapting, which can greatly reduce the intensity of altitude sickness.

You can take some altitude sickness drugs and health food to relieve altitude sickness:

Gaoyuankang: a medicine for preventing and treating acute altitude sickness.

Gao Yuan 'an: Health food helps to alleviate altitude sickness.

Rhodiola and its preparation: Tibetan traditional health food, which is helpful to enhance physical fitness and relieve altitude sickness. Take it 10 day before entering the plateau.

Dinokang capsule: OTC Chinese patent medicine, which can relieve myocardial ischemia and help alleviate altitude sickness.

Baifuning (note that it is an additive, like Fenbid, it is a phenol coffee tablet): It helps to control headaches caused by altitude sickness, and Fenbid phenol coffee tablets are also available to travelers.

American ginseng: It helps to relieve fatigue, enhance physical fitness and reduce altitude sickness.

Quick-acting Jiuxin Pill: Take it when altitude sickness occurs, which helps to relieve altitude sickness.

Danshen Dripping Pills: Treating Cardiovascular Diseases. Helps to alleviate altitude sickness.

The symptoms of altitude sickness can be eliminated within 1-2 days for people with strong adaptability to altitude, and it takes 3-7 days for people with weak adaptability. If you can adapt, you can drink more butter tea, which also has a certain effect on relieving altitude sickness.

Some people may experience altitude sickness when they first travel to the plateau. Symptoms include headache, chest tightness, shortness of breath, palpitation, nausea and vomiting, cyanosis of lips, insomnia, dreaminess and high blood pressure. These symptoms are obvious in the first day or two, and will gradually reduce or disappear in the future; However, due to fatigue, colds, upper respiratory tract infections and other reasons, there are also very few people whose symptoms may gradually worsen and develop into high altitude pulmonary edema or high altitude cerebral edema. Areas above 3000 meters above sea level are called plateau areas. It is characterized by low air pressure and low oxygen concentration in the air, which easily leads to human hypoxia, causing altitude sickness including acute altitude sickness, altitude pulmonary edema, altitude cerebral edema and so on. Headache, dizziness, palpitation, shortness of breath and other reactions will occur when you enter the plateau above 3000 meters in a short time. Severe cases include loss of appetite, nausea, vomiting, insomnia, fatigue, abdominal distension and chest tightness. Check for slight cyanosis of lips and facial edema. It's called acute altitude sickness. People often advocate oxygen inhalation to relieve discomfort. Of course, oxygen inhalation can temporarily relieve chest tightness, shortness of breath, dyspnea and other symptoms, but after stopping oxygen inhalation, the symptoms will reappear. This has delayed the time to adapt to the plateau. We advocate that if the above symptoms are not serious, especially during rest, it is best not to take oxygen. This will help you adapt to the plateau environment more quickly. Just entering the plateau, don't overeat, so as not to increase the burden on the digestive organs and make them adapt to this environment well. It's best not to drink or smoke. Eat more foods rich in vitamins such as vegetables and fruits. However, it must also be noted that if the above symptoms become more and more serious after entering the plateau, especially during rest, you should immediately take oxygen and go to the hospital for treatment. Prevent the adverse consequences caused by "acute high altitude pulmonary edema". Prescription to prevent altitude sickness: take Danshen tablets two weeks or a month before departure, three times a day, three tablets each time. In addition, it is best to take American ginseng tablets with you. Taking it when you have altitude sickness can relieve discomfort.

In addition, the oxidation and antioxidant capacity of healthy standard body in the long-term living environment are roughly the same (the oxidation capacity of people with diseases is much higher than the antioxidant capacity), but after entering the plateau, the total amount of oxidative decomposition to maintain normal metabolism remains unchanged, while the total amount of oxygen intake decreases and the antioxidant capacity weakens, so altitude sickness will occur to varying degrees. Therefore, in addition to taking the above drugs to prevent altitude sickness, it is best to prepare foods containing antioxidants and vitamins, such as vitamin E, vitamin C, asta (abbreviated as astaxanthin), β -carotene and so on. And eat grapes (including grape seeds), radish (containing β-carotene) and shredded radish to stir-fry shrimp (a common home-cooked dish in plateau areas, shrimp contains the strongest antioxidant astaxanthin, and radish contains β-carotene). Especially the "donkey friends" who travel on the road are prone to fatigue after driving for a long time, so it is necessary to strengthen the supplement of standby altitude sickness drugs and antioxidant foods.

The key to overcoming altitude sickness is to overcome your inner fears. Never rely on oxygen.

Precautionary points

For tourists at high altitude, the prevention of altitude sickness is an important life-threatening problem. Prevention points and simple first aid knowledge should be understood in advance.

Do a good job in physical examination to prevent altitude sickness, and do a good job in the hospital you want to go to before traveling at altitude. Patients with chronic obstructive pulmonary disease, interstitial lung disease, various respiratory insufficiency, organic heart disease, cerebrovascular disease, hypertension, gastrointestinal diseases, neuropsychiatric diseases, severe chronic diseases, etc. Not suitable for plateau tourism. When the safety is uncertain, hypoxia test should be carried out.

Physical and mental preparation (1) Psychological preparation: To eliminate the fear, you can learn about the plateau environment, characteristics and medical care knowledge from books and experienced tourists, and enhance your self-confidence. (2) do adaptive exercise. Such as mountain climbing, long-distance running, walking with load, etc. , increase vital capacity and enhance adaptability. (3) Understand the local climate characteristics, bring enough clothes, pay attention to cold and warmth, and avoid acute upper respiratory tract infection. In order to prevent altitude sickness, adaptation training should pay attention to: (1) keep a good attitude, eliminate unnecessary fear of altitude sickness, avoid excessive mental stress, and let the body get full rest. (2) avoid catching a cold. The plateau climate is cold, and the temperature difference between day and night is large. After catching cold, the body is prone to respiratory tract infection and acute altitude sickness. (3) Avoid strenuous activities and heavy physical labor in the first two days, and climb slowly, which is conducive to the gradual adaptation of the body. (4) Eating high-sugar and high-quality protein food is beneficial to overcome the adverse effects of hypoxia. 5] Do not smoke, drink or drink less to reduce the consumption of oxygen. [6] It is best to take health care products for preventing altitude sickness for 3-5 days after entering the plateau.
