Full Answer

Adults breathe about 6.3 to 8.4 million breaths per year. People who live to 80 take many more than 500 million breaths in their lifetimes.

Children breathe about 44 times per minute. Respiration rates may increase because of illness, fever and other conditions. Between these factors and vigorous physical activity, the number of breaths per day, year and lifetime could be much higher than estimated with these figures.
