How many breaths do you take in a lifetime?
At 12 to 20 breaths a minute, an adult takes roughly 20,000 breaths a day and around 600 million in a lifetime.
Source: Normal adult respiratory rate (Cleveland Clinic).
Context
Around 600 million. An adult breathes 12 to 20 times a minute at rest, which comes to roughly 20,000 breaths a day, and a lifetime of days multiplies it out.
The resting rate is the normal adult range used by clinicians, including the Cleveland Clinic. Exercise, sleep and illness push the daily count up or down.
