During hypoxia, which is a reduction in the oxygen content in the breathing air, the body initiates a variety of biochemical adaptation processes. These processes naturally vary depending on individual genetics, fitness level, and the duration of hypoxia. Here are some of the most common reactions:
Our breathing rhythm intensifies – we breathe faster and deeper. This allows the body to take in more oxygen and efficiently expel carbon dioxide.
The heart begins to beat faster and pumps more blood through the body. This is to transport a greater amount of oxygen to the brain and other vital organs.
In essence, our body adapts to the available oxygen content, as if we were leisurely enjoying a coffee on the Zugspitze (with its summit cross at an altitude of 2,960 meters). It is this natural adaptability that is activated and trained during hypoxia.
