What is that threshold or extra “push” when you take a deep breath or yawn?

Like your lungs fill up as usual, but this time there’s this extra “push” that feels so refreshing

Edit: I forgot the colon after and that just feels gross

Deep breaths and yawns increase oxygen intake, which slows heart rate, lowers blood pressure, and calms you down. I suspect this is also why yawning is contagious cross species(like feline<->primate). It would be an adaptive behavior for both parties to calm down, kind of like a win win “time out” when nature is brutal. Even a tiny bit helps in the long term evolutionary game.
