So, in Part 1 we finished by saying that our breathing basically regulated by the amount of CO2 in our blood, not O2.
But we still need O2, right? Of course, we do! :-) We need O2 to break down food which we take and produce biochemical energy. This is what you can call LIFE :-) It happens in our cells (this is why it calls cellular respiration). And where from are we getting CO2? Yes, there is a little bit CO2 in the air which we inhale, about 0.04% (did you know that it was about 0.028% in the pre-industrial era?), but when we exhale, it is already 4-5.3%!! More than 100 times increasing! Where is it come from??
Do you remember cellular breathing (any idea how to pronounce cellular?), so, it has actually two parts. Produce energy and remove waste products. So, our CO2 is a waste product of producing this biochemical energy.
More energy you produce, more CO2 you will produce. As simple as that.
And why we are talking about it?
If you hold your breath and you are not relaxed (for example for STA) or your technique is not efficient (for example for DYN) then you are going to produce energy and CO2 as a result. And then you want to breathe very quickly! And the opposite is true, if you are relaxed and using the efficient technique, then your breathing reflex come later. What is the breathing reflex? Let's talk about it next time ;-)
And by the way, is CO2 really waste product and we don't need it? Not exactly....But this is another story as well!
