That's like 60-something, greater than 60% lower if...

if men use it four to seven times a week versus once.

Again, a dose-dependent thing.

And this is all work from Dr. Jari Laukonen.

He's in the University of Eastern Finland and just one of the world experts on sauna use.

The more you do the sauna or any sort of heat stress, whether it's a hot tub or jacuzzi, you become adapted.

You basically start to sweat at a lower core body temperature to cool yourself down.

All these sort of physiological changes start to happen earlier.

And so I stay in for like 30 minutes.

So I stay in a long time.

That's a lot.

You have to listen to your body.

Most of the studies that I just talked about were from the duration, the time spent in the sauna when I said 50% reduction in cardiovascular disease-related death.

What was shown was that men that were in the sauna for only 11 minutes, even if they used it four to seven times a week, that reduction was only like 8% instead of 50.

It had to be greater than...

19 minutes, so like 20 minutes is the sweet spot, at about 174 degrees Fahrenheit.

To me, that's a very strong data that this is more causal than some corollary thing because that's always the problem with observational studies, including these, which they corrected for a whole host of factors like cholesterol.

you know, exercise, just everything, everything under the sun.

I mean, they correct it for those.

And on top of that, you have the dose dependent nature of the duration, the time spent in the sauna and the frequency.
