Yes.

However, baseline changes, which we're actually looking at more of like fine blood pressure changes that are occurring.

So that's actually more the sign of is someone actually making a trait change, which is as we breathe,

Is blood pressure following very specifically, like a fine-tuned fork with your breathing?

If it's not, then we have what's called low baroreflex gain.

The nervous system's having a hard time keeping up.

It's that cruise control example.

Really hard time adapting.

But when we have high baroreflex gain, which comes from all this consistent training of HRV biofeedback or resonance breathing, then that fine-tunement then results in our ability to adapt quickly,

And that quick adaptation then results in blood pressure moving at an instant when you tell it and very smoothly when you tell it.

So low frequency power in HRV can increase significantly as well.

But high frequency power is another one.

So at resting baseline, we're actually looking at changes in what's called high frequency power.

And we see that that can change an order of magnitude anywhere from 20, 40, 50 percent.

So when you are looking at your WHOOP score every single morning and you see that number that is HRV, it's in milliseconds, we call that a time domain indice.

A time domain indice is exactly as it says.

It's just looking at the time difference between successive heartbeats.

We can take the data, which is all those raw intervals between heartbeats, so all those time intervals, and we can...

apply some mathematical equations and algorithms to it something called an fft or a fast foyer transformation which is essentially when we take those data run it through a prism and then get the component rhythm values of that best way to explain this because that's probably very confusing is to think about this as being analogous to an eeg so i put electrodes all over your head i look at your brain wave states and the amount of signaling and power of that brain wave and

And I get this raw EEG.
