So we've actually plotted this.

We did a bunch of stuff probably four or five years ago.

We didn't publish it.

just we were, we were tinkering around with stuff and we started looking at HRV.

Uh, we brought it up just in case people aren't aware.

It's a marker of overall recovery.

Like we'll kind of keep it at that for now.

And when you go into the ice, whether this is anywhere between 30 to 50 degrees for a minute to five minutes, you generally going to get out of that ice and you will see sympathetic drive fight or flight is elevated like pretty consistently.

That said, uh,

We plotted this every 15 minutes for up to three hours post, and you just continually see a rise in parasympathetic drive for up to three hours post.

So I don't know when he's using it, but I would be willing to strongly bet he is far more down regulated going to bed when he does the ice for that exact reason.

You got to time it appropriately, because again, when you get in the ice and immediately somewhere between 15 to 30 minutes post ice exposure, you'll be more sympathetically driven.

But after that, for several hours, and most of the people, they were far more.

And I'm talking about like 20 to 50% reductions, or elevations rather, in HRV, meaning more passive, for many hours.

And we stopped actually collecting the data at three hours.

So I don't even know how long that thing lasts.

But I'm not surprised.

Yeah, we have a non-small amount of people who like to do it in the evening as well.

Yeah.

I'm not surprised at all that he likes it.
