I heard Nestor's interview with Joe Rogan, was intrigued and I decided to try it on my runs (~7 miles 2-3x per week), where I typically breathe through my mouth.

While running I breathed exclusively through my nose. My expectation was that I wouldn't be able to sustain it for the entire duration of the run. Surprisingly I was able to.

Overall I felt less winded that I typically do when breathing through my mouth. I thought my overall pace and/or avg heartbeat might be slower when breathing nasally but, according to my activity tracker, that's not the case. The other thing I noticed is that the 'runner's high' I typically get after a run was somewhat muted when breathing nasally.

I'd love to see more research in this area. I wonder if I'm depriving my brain of needed oxygen or if there are benefits to getting more CO2 than usual.

I never get runners high, but have always attributed that to me just being weird, as usual. Ever sunce I was little I have a habit, reflex, or whatever one should call it, to breath quite slowly and deliberately during any extended exercise. Never thought it could be related, but maybe it is?
