Essentially, it's almost ironic that if individuals are transitioning into heat stroke, they actually vasoconstrict and they stop sweating.

And that's a pathological situation.

I couldn't begin to explain it.

But essentially, you are just feeling exhausted.

You're feeling miserable.

The heart rate is very high.

Your heart rate goes up as your core temperature goes up, called cardiac drift.

So you just feel rotten.

It's not a danger signal that you can translate immediately into, nope, I'm going into heat stroke.

That's why people can overcome their bad feeling with motivation to continue going, to work harder.

So there have been a number of high-profile athletic deaths due to heat stroke that were during practice.

Not in competition when people are really trying to do it, but in practice, which shows they were just motivated to push forward.

Where the portals are, are in the glabrous skin.

Big word, okay?

Glabrous just means no hair.

So it's the hairless skin.

You say, well, most of my body is without hair.

No.

No.

Most of your body has hair follicles.
