How many breaths do you take in a day?

ANSWER

Your lungs work all day and night, whether you’re awake or asleep. That’s 20,000 or so breaths per day! By the time you’re 50, you have taken around 400 million breaths. Diseases like COVID-19, which can attack the lungs, shine a light on how important these organs are. They get oxygen into your blood and into every cell in your body. And they help get rid of carbon dioxide (CO2), which is toxic if you have too much.
