I mean, isn’t oxygen good fit your body?
In: Biology
Oxygen is good for your body (to a certain extent), but that’s not what you worry about with hyperventilation. When you exhale, you blow off carbon dioxide. Carbon dioxide is one of the main players in your blood chemistry. If you hyperventilate, you exhale more and more carbon dioxide. You can end up exhaling so much carbon dioxide that you can cause respiratory alkalosis, which can result in all sorts of problems. By breathing into a bag, you can breathe back in some of the carbon dioxide you breathed out so you can maintain appropriate carbon dioxide levels in your blood.
