hypocapnia

But once again, if there's not enough getting back to the brain, that creates issues.

You can also have hyperventilation leading to hypocapnia.

Hypocapnia induces cerebral vasoconstriction and peripheral vasodilation.

So you're now constricting all the blood vessels in your brain, trying to get stuff to where you want it to be.

But if you are dilating peripherally, then what does that do, right? That is going to cause more blood pulling because you cannot be vasodilated in your legs and get stuff back to your heart.

It just doesn't work that well.

Now, for those not familiar with hypocapnia, this is going to be talking about carbon dioxide levels due to shallow breathing or breathing too fast, okay? So...

You've got to have a balance of carbon dioxide and not.
