Doctors from the Department of Alpine Diseases and Cardiovascular Diseases of Xizang Autonomous Region People's Hospital reminded visitors to Tibet to prepare enough clothes and pay attention to cold and warmth during the rainy season. Although the temperature of direct sunlight at noon on the plateau is high, the temperature difference between morning and evening is large, and tourists who come to Tibet for the first time are easy to catch a cold because they are not familiar with the climate. A cold and fever will increase the body's oxygen consumption and aggravate altitude sickness. Cold virus can affect the body, easily induce high altitude pulmonary edema, and even cause brain edema in extreme cases.

Extended data:

Before entering the mountain, both psychological and physical qualities should be adapted. If possible, it is best to carry out intermittent hypoxic stimulation and acclimatization exercise in the low-pressure cabin, so that the body can have certain physiological adjustment to the hypoxic environment from the plain to the plateau.

At present, it is considered that climbing is the safest and safest way to prevent acute altitude sickness except those who are particularly prone to hypoxia. Experts suggest that novices who want to enter the plateau above 4000m usually stay at 2500 ~ 3000 m for 2 ~ 3 days, and then the rising speed should not exceed 600 ~ 900 m every day.
