Research into breathing for cycling

After inhaling a pollen laden bee (or at least having it hit the back of my throat and choking on the pollen) I've taken to breathing through clenched teeth in summer. Feels like half way between nose and mouth breathing.

Apparently, a book recently came out on this topic: Breath, by James Nestor.

Grant Petersen, of Rivendell Bikes, mentions it in a few of his Blaughs from last year.

I've been experimenting, and yes--it's only one person, it's not a rigorous study, but guess what?—I don't have a lab and this is just a blahg.. Aside from what ever longterm health advantages there are, I wonder and am still wondering about riding whilst sucking in and blowing out air thru the nostrils.

And, one of the fun deals about not racing or caring about that stuff, is that I can experiment without risking not getting my contract renewed next racing season.

I may not "care" about speed, but I ride the same rides all the time, and based on my effort level, I can tell how long it a variety of one-to-five minute climbs is going to take. On a one-minute climb, I can tell within 2 seconds. On a five-minute climb, within ten seconds, usually six. Nose breathing is new to my internal Olympic games, so after 20 years of mouth-breathing these same climbs, I started nose-breathing them just for fun. 

Today, Groundhog Day, a sprint up a gradual hill that usually takes me 37 seconds, and my fastest is 35, took only 34, nose-breathing on my Atlantis with wing-widened pedals, and fully racked and bagged. I'm nose-breathing all the time now, except when I lapse. Try that book. 

Winter sucking in air through the mouth, soon will breathe in the first bug, then trying to get enough air through the nose until winter comes around...
Good luck with the research.
