What are the characteristics of altitude reaction and the methods to prevent altitude reaction
4hw.com.cn: in recent years, many friends will choose to go to Tibet to feel the grandeur of the prairie. However, Tibet is located on the plateau and is not suitable for everyone. Some people will have altitude reaction in Tibet. What are the characteristics of altitude reaction and how to prevent it? Let's take a look with Xiaobian.
Symptoms of altitude sickness
Symptoms of altitude sickness include vomiting, tinnitus, headache, urgent breathing, loss of appetite, fever, drowsiness. In severe cases, there will be dullness, restlessness, hyperactivity, thinking ability, memory loss, abnormal hearing, vision, smell, taste, hallucination, edema, shock or spasm.
What is altitude sickness
The reason for altitude sickness is that the higher the altitude, the thinner the air, and the lower the air pressure. Therefore, the oxygen pressure required by the human body also decreases, but the oxygen content required by the human body remains unchanged. In order to maintain the oxygen content required by the human body in the blood, it is necessary to increase the content of red blood cells, but it takes a few days for the human body to automatically increase the content of red blood cells, Therefore, when entering the mountainous area, the human body will have no time to adapt to the sudden increase in height, resulting in insufficient oxygen supply in the body. The higher the height, the shorter the transition time, and the more severe the reaction. This physiological reaction is generally called 'altitude reaction'.
Prevention of altitude sickness
The prevention methods are: the speed of climbing should not be too fast. It is best to keep a steady pace and cooperate with breathing. At the same time, it should be adjusted according to the rapidity of the slope, so that the amount of exercise is in direct proportion to breathing, especially to avoid rapid breathing. The rising height shall be gradually increased, and the climbing height every day shall be controlled to adapt to the environment of low mountain air pressure and thin air. The journey should not be too urgent. Sleep and diet should be sufficient and normal. Take short breaks frequently. During the rest, strengthen the circulatory function and high adaptation with soft exercises and deep breathing. Usually, more physical training should be done to increase the oxygen intake function.
