How many times does the average human breathe in 24 hours?

The average rate of respiration in a healthy adult human is twelve breaths per minute. This is based on an ‘at rest’ basis and assume the adult is healthy, without fever or encountering breathing difficulties.

Exercise will alter the rate.

Newborns, infant and children will have differing rates of respiration

Based on twelve breaths per minute a human will take 17,280 breaths in a day (12 x 60 x 24)
