Yeah, so ice bath. So this is really interesting. So, you know, I think, this is a very, very big data set, right? There's lots of people on our platform who ice plunge very consistently. So what we did is we bucketed the group into high fit and low fit.

Okay. So folks who are high fit, we just looked at normative values. So we're just, you know, heart rate variability, resting heart rate, um, BMI, like all that just basically kind of created. Yeah. And just like a high fit group and a low fit group. And then we looked at the frequency of their ice bath.

So what's great on whoop is you basically can record when you start an ice bath and when you ended ice bath. So we have these really nice timestamps. So some people forget to stop it and it ends up being like- 12 hours.

So those we had to throw out, obviously, because those are not going to be accurate. But we could actually go back and tell in the data. We did this for some, but then it got too much. We can actually see when it ended because there's very clear responses, physiological responses when you're in the ice bath. But anyway, we had plenty of data in both this high fit and low fit group.

And basically what we saw, the fitter you are, The more you ice bath, the less good it is for your recovery when you're ice bathing more than three times per week.

We see a decline in your markers of recovery after three days of ice bath. And your ice bath is more effective on days that you are not exercising. Then going back, exercise, of course, is a hormetic stressor as well.

So when you're layering on top just all the stress that's happening during the day, the stress of your workout, the stress of the ice bath, it has a deleterious effect on markers of recovery. But for the low-fit people, it's only beneficial.
