What are hypoxia and hyperoxia?

Mar. 31, 2026

Hypoxia is by definition a lack of oxygen in the body and tissues, which leads to various adaptation mechanisms that can have a positive effect on energy supply. However, to induce hypoxia, one does not necessarily have to go to the mountains. One can also simulate it by breathing in a low level of oxygen through a mask. In addition to the phases with moderate hypoxia, in which little oxygen is inhaled, there are also phases in IHT in which oxygen is inhaled in the usual concentration (normoxic phases). Thus, there is alternation between the two phases. Hence the name interval hypoxia training.


IHHT can be seen as a further development of IHT and should lead to a faster recovery after hypoxia. IHHT involves replacing periods of normal oxygenation with periods of high oxygenation. As a result, the patient breathes in more oxygen than usual and the body is supplied with more oxygen than usual. Consequently, exactly the opposite of hypoxia takes place here, namely hyperoxia. As with IHT, IHHT also alternates between the two phases.


Longfian IHHT system provide a personalised IHHT experience. The alternating periods of reduced oxygen (hypoxia) and increased oxygen (hyperoxia), lead to more efficient transport and utilisation of oxygen by body tissue and train your body to use oxygen more efficiently, delivering the positive effects of high altitude right to you.
