If getting water in our lungs is dangerous, and humid air can contains a lot of water, sometimes so much that *everything* it touches gets wet, then why is it okay to breathe this air?
In: 6
Liquid water in large amounts is dangerous because it prevents the exchange of air.
Our breath has water vapour in it to begin with because some water comes out of the blood in the lungs and is then breathed out. The water in the air when it is humid is water vapour (a gas) and not liquid water.
