Answer 1

The nose is designed to warm and moisten the air, and also limit bacteria and particles from getting down into the lungs. This is good, and keeps your lungs in peak health.

You can take air in faster through the mouth, but at the expense of directly pulling in more junk, and colder drier air (which can cause inflammation or reduce the lung’s ability to get oxygen from the air).

It’s not uncommon for martial artists and certain athletes to be taught to breath in through their nose and out through their mouth.
