Yes, in the breath hold.

So it goes directly to the brainstem.

And in the brainstem, you have the mechanisms to react on CO2 and alkalinity, but there is no CO2.

So the brain thinks there is danger.

The non-thinking brain thinks or acts as if chemically there is danger.

What happens?

Hypothalamus, pituitary gland, adrenal glands, a adrenal spike.

After 90 seconds of not breathing, after exhalation, you got five times more blood flowing, flushing into the heart and brain.

It's all survival reflexes.

The thing is, anything that should not be in the body is being exposed because it hits direct to the greatest of possible functionality of our being to survive this situation while you feel great.

Yeah.

And this was over a 20-minute controlled period.

So is it controlled hyperventilation and then a long pause, then controlled hyperventilation and a long pause?

Can we demonstrate it maybe?

We got a lack of words and definition about this.

I say hyperventilation is a kind of wrong state of breathing.

Okay.

And what I say is a deep breathing.

So is it letting go?

Yeah, very simple.
