Potential Side Effects of Hypoxia Training

High-Altitude Pulmonary Edema (HAPE)

High-Altitude Pulmonary Edema (HAPE) is characterized by the accumulation of fluid in the lungs, which can severely impair oxygen exchange in the alveoli. HAPE occurs at altitudes above 3,000 meters, with an incidence rate of 0.7% among mountaineers. Key symptoms include headaches, sudden decline in performance, dyspnea at rest, cyanosis, vomiting, and fever. If any of these symptoms appear, the session must be immediately terminated.

Warning

If you experience headaches, sudden decline in performance, dyspnea at rest (shortness of breath without physical exertion), cyanosis, vomiting, or fever, the training session must be immediately stopped.
