I continue doing breathing exercises and observing how my skin temp rises in the process

Typically, I do them while hooked up to my BiPAP and wearing a mouth guard, but today I discovered an exercise I needed to do without those, because it involved deep inhales through the nose alternating with exhales through the mouth, as if blowing out a candle. I liked the voice of the narrator and her accent. Not sure it was British but definitely not American.

These exercises are fun and seeing the skin temperature respond positively to them provides a reinforcement I like.
