It takes weeks for that to happen.

You're well into that problem.

And when you start seeing changes in resting heart rate, you are so far down that road that you've like, we should have saw this weeks ago.

100%.

Yeah.

You will not see a change in first thing resting heart rate for a very long time into problems.

The reason why people like HRV more is because it is far more stable.

It is also, like resting heart rate, nonspecific.

So you don't know what's happening, but that variability that you're mentioning that Ben talked about earlier, that's also the benefit.

Once you establish somebody's standard deviation, what do they normally fluctuate, right?

Some people are going to be really neurologically, nervous system is going to be super stable.

Some people's nervous system is really unstable, right?

That itself is a marker.

How wide you range on your daily HRV is incredibly telling to what's going on in your system.

Because of that, that sensitivity, I can see things happening really quickly.

Now, some of the common mistakes with HRV are looking at the flat score, right?

You know if I said right now, like, Ronald, what's your resting heart rate?

And if I said your resting heart rate's 100 beats per minute, you know that's bad.

If I said right now your HRV's 100,

You have no idea if that means anything.
