Because the human body hypoxic diseases caused by high altitude hypoxia environment, called the high altitude disease. High speed and the intensity of labor is the occurrence and the degree of altitude sickness is proportional to the.
High altitude disease is divided into acute mountain sickness, high altitude pulmonary edema, acute high altitude cerebral edema in three types, which can be combined with. Acute high altitude reaction performance of altitude sickness, dizziness, headache, palpitation, palpitations, loss of appetite, fatigue, shortness of breath, nausea and vomiting and other symptoms of acute hypoxia of high altitude pulmonary edema; cough, chest tightness, then there will be vomiting pink foam sputum, clinical manifestations of acute high altitude cerebral edema; the change of consciousness, with vague symptoms, what is more likely to cause death.

For there is no entered the plateau of the people, by 1 to 3 months of acclimatization training, most people can adapt to the situation. For examination by a doctor, to allow tourists to Tibet with cerebrovascular disease in Tibet, a few months ago, it should be to strengthen the physical exercise, in order to gradually improve the tolerance to hypoxia. But a few days ago in Tibet, it is necessary to have a good rest, do not do strenuous exercise.
Due to mental stress, fatigue, colds, fever, poor nutrition, low temperature and other circumstances may cause altitude sickness. Therefore, the first day after Tibet, must be in the hotel to rest, not to mention the weights or running, at the same time as far as possible to avoid the reception, dinner and visits and other outdoor activities, so as to reduce the oxygen consumption of the body, as much as possible so that the body is in low oxygen condition.
