Hyper retention, follows some sort of hyperventilation breathing.
We can hyperventilate and back it up with a mild physical effort that increases the level of CO2 in the blood stream…. mild exercising. We can also hyperventilate without making a physical effort. When doing that, we reduce the level of CO2 in the blood stream.
There are many different variations for hyperventilating statically. Different counts for inhaling and exhaling, mainly from the mouth but also from the nose. What is common to all hyperventilation-breathing methods, is a fast tempo of breathing.
After hyperventilating, we can retain our breath for a relatively longer period of time compared to retaining the breath without prior hyperventilation.
Holding the breath for a longer period of time, is not a result of saturating the blood with oxygen but rather reducing the amount of CO2 in the blood stream.
Since the urge to breath is triggered, depending on the level of CO2 in the blood, when we hyperventilate and expel CO2, we “trick the body” that is given a false indication.
Some believe that static hyperventilation is damaging because it simulates states such as anxiety and over-stress. Others believe that a controlled simulation of anxiety and over-stress, has benefits in preparing the body for these situations.
