So the best evidence is you want to be between 174 Fahrenheit to 212 Fahrenheit.

That's your window.

So what we're doing now is one of the primary benefits of the sauna is when you go in there, your core body temperature, when it gets to about 102 degrees Fahrenheit, it triggers the release of heat shock proteins.

So these are like little machines, protein machines that get spun up and they go around and fix shit.

They fix broken proteins.

Like minions.

Yeah, like flooding your body, doing good stuff.

But it only gets triggered when your core body temperature hits a certain level.

And so if you're not hot enough to sauna, but they're very hard to measure.

So we're currently setting up a lab, a wet lab in my house.

We can measure this.

We're going to try to measure my heat shock protein release

on various temperatures, various durations.

So what we've been looking, cause I've been doing core temperature out of my ear lately, but you can't, the gold standard measurement is rectal, but you've got to do that.

You've got to like be inside the ass for like two to three minutes with a long probe.

That's farm work.

So I'm struggling with that one.

Like I do, I do, I do a lot of stuff, but like, man, I was like, guys, can we find an alternative way of doing this?

So we're going to do blood.

We're going to measure heat shock protein release.
