Bohr effect.
shift in the oxygen dissociation curve caused by changes in the concentration of carbon dioxide or the pH of the environment

We've unlearned breathing and it's quietly wrecking health
Nestor argues that mouth breathing, fast shallow breaths, and low carbon dioxide tolerance drive snoring, anxiety, asthma, and chronic strain more than oxygen intake ever does.

About Bohr effect
The Bohr effect is a phenomenon first described in 1904 by the Danish physiologist Christian Bohr (who was also the father of the physicist and Nobel laureate Niels Bohr). Hemoglobin's oxygen binding affinity (see oxygen–haemoglobin dissociation curve) is inversely related both to acidity and to the concentration of carbon dioxide. That is, the Bohr effect refers to the shift in the oxygen dissociation curve caused by changes in the concentration of carbon dioxide or the pH of the environment. Since carbon dioxide reacts with water to form carbonic acid, an increase in CO2 results in a decrease in blood pH, resulting in hemoglobin proteins releasing their load of oxygen. Conversely, a decrease in carbon dioxide provokes an increase in pH, which results in hemoglobin picking up more oxygen.
