You typically only breathe out of one nostril at a time

[Tedday2223]

Yes, your nostrils share the work when it comes to inhaling, but it's a little more complicated than you might think. Rather than both nostrils taking in the same amount of air when you breathe in, you actually inhale most of your oxygen through one nostril at a time. The active nostril actually switches every few hours. Don't believe us? Put your finger under your nose and test it yourself.

That’s such a cool fact! It’s amazing how our bodies work in ways we don’t always notice. The nostril switch really shows how intricate even something as simple as breathing can be!
