An organ taking up so much space in our heads must be meant for more than only smelling flowers. The nose is one of the most underestimated body parts, and one of the most important ones when it comes to our everyday health.

Here I list some of the reasons why.

The air gets heated and humidified

When inhaling through the nose the air gets prepared for the lungs. The lungs like the air served warm and humid, then the gas exchange works better. When we exhale through the nose the nostrils gets reheated and moisturised, ready for the next inhalation.

And, if we exhale through the mouth we loose 42% more water than exhaling through the nose!
