In addition, breathing through the nose also exposes air to maximum contact with mucus in the nose and throat which is secreted in the lungs and passed up and out by lots of little hairs (if I remember correctly). The mucus is there to trap particles in the air to protect the lungs from damage.
I still mainly breath through my mouth when diving with my FFM as I find this the most comfortable. If I reduced the breathing resistance on the reg so I have positive flow then it is very easy to breath through the nose BUT I am too mean to waste gas (and bottom time) in this fashion.
Whether this is down to years of using the "normal set up" to start with, or exertion I don't know. I suspect
