Intermittent hypoxia method and application thereof in aspect of improving cognitive function

The invention discloses application of intermittent hypoxia in the aspect of improving a cognitive function. According to the intermittent hypoxia, oxygen is given in a hypoxia-normoxia alternate mode, the time for hypoxia is 2-6 hours, and oxygen partial pressure is 70.8-141.2 mmHg; the time for normoxia is 18-22 hours, and oxygen partial pressure is 140.8-181.2 mmHg; and continuous processing is performed for 7-42 days. The intermittent hypoxia scheme can be used for improving the cognitive function of mammals, improving learning and memory capabilities and treating cognitive impairment and senile dementia of the mammals.
