measurementDuring a stress response, the human respiratory rate increases from a resting rate of 12-16 breaths per minute to 20-30 breaths per minute to increase oxygen delivery to muscles.

claimThe respiratory system maintains blood pH by adjusting the breathing rate to remove excess carbon dioxide, which prevents the formation of carbonic acid that would otherwise lower blood pH.

measurementThe average human breathing rate at rest is 12–20 breaths per minute, with each breath moving approximately 500 milliliters of air.

measurementDuring seated meditation at a middle level of samatha, the breathing rate may drop to two or three breaths per minute, compared to the approximately fifteen breaths per minute observed in normal adults at sea level, as reported by Lazar et al. (2000) and Austin (2006).

measurementDuring meditation, skin conductivity, oxygen consumption, heart rate, blood pressure, cortisol levels, muscle tone, urinary vanillyl mandelic acid (VMA) levels, and breathing rate all decrease, according to research by Jevning et al. (1992), Benson (2000), Lazar et al. (2005), and Austin (2006).
