And one of the things she found in her second, actually, two studies in the second one found that you'll see something like your likelihood of experiencing moderate to high stress, one beat per minute increase in resting heart rate gave like a 1% to 2% increase in risk.

but a one breath per minute change in resting heart rate was a 20 to 30% increase in likelihood of experiencing moderate to high stress, which is a way of saying that stuff will flag way before resting heart rate.

Resting heart rate didn't do anything, didn't tell them anything about it, but HRV and specifically respiratory rate shot way up.

You can see acute stress.

If I look at someone's day in the morning and your normal respiratory rate is say 12 breaths per minute overnight, and you're at 14, I'm like, whoa.

something's going on.

If you're at 14 for two days in a row, boom, you're going to get sick the next day or you're already sick or something like, Hey, what's going on, Ronnie?

Okay.

Like what's going on?

Like, no, my God, like something's happening.

And so for me, when we're coaching people, like we're coaching them, I don't want to wait six weeks to start seeing problems happen.

I need to go like, Hey, this happened right now.

What the heck has happened?

What's going on?

And from our opinion, HRV and respiratory rate, we'll jump off the charts way before resting heart

Depends on the device you're using.

If you start going out to the wrist and the hand, we start losing accuracy, right?

If you're actually using a chest strap,

We're getting better.

When we really care about it, like in our actually like sleep testing stuff, we're gonna have a device directly on your chest.
