What should you pay attention to when traveling to Tibet for the first time?

Some people who are traveling to plateau for the first time may suffer from altitude sickness. Symptoms include headache, chest tightness, shortness of breath, palpitations, nausea and vomiting, cyanosis of the lips, insomnia, dreaminess, and possibly increased blood pressure. These symptoms are obvious in the first or second day, and then gradually reduce or disappear; however, in a very small number of cases, due to fatigue, cold, upper respiratory tract infection, etc., the symptoms may gradually worsen and develop into high altitude pulmonary edema or high altitude cerebral edema. Areas with an altitude above 2,700 meters are called plateau areas. It is characterized by low pressure and low oxygen concentration in the air, which can easily lead to hypoxia in the human body and cause altitude sickness, including acute mountain sickness, high altitude cerebral edema, high altitude pulmonary edema, etc. Entering a plateau above 2,700 meters for a short period of time can cause reactions such as headache, dizziness, palpitations, and shortness of breath. Severe cases also include loss of appetite, nausea, vomiting, insomnia, fatigue, abdominal distension and chest tightness. Examination revealed mild cyanosis of the lips and facial swelling. It's called acute altitude sickness. Oxygen is often advocated 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. In this way, the time to adapt to the plateau is delayed. We advocate that if your above-mentioned symptoms are not very serious, especially if they are mild at rest, it is best not to inhale oxygen. This will allow you to adapt to the plateau environment faster. When you first enter the plateau, do not overeat to avoid increasing the burden on the digestive organs so that they can adapt well to this environment. It is best not to drink alcohol or take oxygen. Eat more vegetables, fruits and other vitamin-rich foods. However, it must also be noted that if the above symptoms become more and more serious after entering the plateau, especially when they are at rest, they should take oxygen immediately and go to the hospital for treatment. To prevent adverse consequences caused by "acute high altitude pulmonary edema". Health products to prevent altitude sickness: You can take 2 Omo oxygen-carrying tablets before departure, and if you experience altitude sickness after entering the plateau, take another 4 tablets.
