Although the body has a strong ability to adapt to the plateau environment, this ability is obviously limited. When a certain altitude is reached, it will lead to irreversible damage to the body. Research shows that the body’s adaptability to hypoxia can be strengthened by means of pre-hypoxia training. Pre-hypoxia training means that after a brief period of hypoxia, the body has a strong resistance and protective effect against subsequent longer or more severe hypoxic injury. One study found that after four to five consecutive repetitions of confined hypoxia in mice, the animal organism’s tolerance to hypoxia was significantly enhanced. Hypoxia in a low-pressure chamber at a simulated altitude of 3000 meters for 2 hours in rats, repeated 4 times, was able to significantly increase the ATP content in myocardial tissue of rats exposed to hypoxia at a simulated altitude of 4000 meters for 24 hours, and improve the mitochondrial respiratory function and mitochondrial membrane fluidity of cardiomyocytes. After repeated intermittent hypoxia using the low-pressure chamber for 30 minutes to 3 hours, with an interval of 1 to 3 days each time, the organism can produce a series of changes similar to the exposure to the plateau environment after so many repetitions, and the habituation ability produced will gradually fade away only 18 to 25 days after the end of decompression hypoxia, but will not be completely lost, and the habituation to hypoxia can be rapidly established when encountering hypoxic stimuli again.
