So if you're a woman, you're jumping in. Yeah. So you're jumping into that icy cold water and you're getting that shock. And that shock is a sympathetic so that you have your flight or fight sensation, which is your sympathetic drive. And you have that deep relaxation, which is your parasympathetic drive.

For women, we get that shock and that sympathetic drive, which increases cortisol, increases our blood glucose and our free fatty acids because the body's like, ah, what is this incredible shock? I've got to get out and run away. For cool water, it's not as intense. So you don't get that sympathetic. You get the initial, and then the body's like, okay, I can deal with this.

I'm going to do some vasoconstriction. I'm going to put more blood sugar to the brain so that the brain understands what's going on and stimulates what we call the vagal nerve. So the vagal nerve is what that parasympathetic nervous system is attached to. So it invokes that calming and you can stay in it, take some deep breaths.

But that said, heat does so much more for a woman's body than cold plunge. So if we're looking for increased parasympathetic drive, we're looking for better metabolic control, we're getting better hormonal control, it's all instigated by sauna work, not by cold plunge.

So the thing with the infrared is it really bypasses when the initial thermoregulation control centers. If you get to a point where it's hot enough and you get that sweat onset and you feel really uncomfortable, then you're hot enough. But you don't have to like stay in there for a half an hour or more being uncomfortable. You bring it up to your sweat response and then you can get out.

And I think that's what people don't like. They're like, oh, I get an infrared and I get warm, but I don't sweat. I'm like, but you need that. You need that uncomfortable heat and uncomfortable sweating to invoke the change.

Yeah, my stepdad has one, but we have a finish sauna. So I use our finish and then I go to my parents' house and I'm like, I'm freezing in your sauna.
