1. When tourists reach the plateau area above 2700 meters above sea level, don't overwork and avoid strenuous physical activity. Don't get too excited on your first day in Lhasa. In order to adapt to the high altitude environment, it is best to sleep more.

2. During the journey, travelers should not drink alcohol, take less baths (only baths), drink more water, and avoid eating too much to avoid consuming too much oxygen.

It's best to take an oxygen bottle for use in case of lack of oxygen. In addition, pay attention to keep warm, especially to prevent colds.

4. If severe altitude sickness occurs, don't continue to a higher altitude, but stay at the original altitude until the symptoms disappear. If the condition worsens further, seek medical attention in time.

5, diet should pay attention not to overeat, to choose some easy to digest and absorb high carbohydrate and multivitamin diet. Because eating indigestible supersaturated food will lead to increased blood circulation in the gastrointestinal tract, increase the burden on the heart and aggravate hypoxia.

6. Bring some chocolate or sugar. Besides being easy to digest and absorb, sugar food consumes less oxygen in the body, so it is timely and effective to supplement energy to alleviate hypoxia. In addition, drink water in moderation, too much will also increase the burden on the heart and aggravate the symptoms of hypoxia.

Harm of hypoxia

Short-term hypoxia will not cause harm to human body. After a period of adaptation or leaving the anoxic environment, the human function will return to normal.

However, persistent and severe hypoxia can lead to diseases and even life-threatening. Oxygen is an important substance to sustain human life. Lack of oxygen for 5 minutes can lead to brain death.

In a sense, life is a redox reaction. A person who doesn't eat for ten days and a half months will starve to death, who will be thirsty if he doesn't drink water for seven or eight days, and will die if he holds his nose and doesn't gasp for a few minutes.

This vividly shows the importance of oxygen to life. Similarly, hypoxia is also one of the important causes of human injury and a series of diseases. Almost all diseases in clinic are related to hypoxia in different pathological stages.
