Normal men, if in a calm state, breathe 12-20 times a minute is a relatively normal phenomenon. If women breathe 1-2 times more than men, it is slightly faster. If it is an infant, breathing can reach 30 times per minute, and the neonatal breathing frequency can reach 40 times per minute.

Therefore, different people's breathing times are different, and the normal range is different. Often during exercise, in addition to the increase of breathing frequency, there will be changes in breathing depth.
