Question

What’s the logic behind breathe in through your nose and out through your mouth?

In: Biology

Answer 1

Your nose is a big filter on your face, hairs and mucus helps catch dirt and germs. It’s also a longer trip to the lungs, giving your body more time to warm the air (more important in cold temps) meaning it’s less of a shock to your lungs.
