Oh, so Gaviscon, so number one, it's got aluminum in it, which should absolutely be avoided. But yeah, it looks like a buffer. It's got an aluminum hydroxide, which is a strong base, so it's neutralizing the stomach acid production. But it's a neutralizing agent, but anything that contains aluminum, you should absolutely avoid.

You know, when we talk about the enzyme that's found in the lining of the blood vessels, when we started this segment, that same enzyme is found in our epithelial cells, in our upper airways, in our sinuses. So just like exercise can activate nitric oxide production in the lining of the blood vessels, deep breathing, nasal breathing activates that enzyme in the epithelial cells of our sinuses.

So just like exercise can activate nitric oxide production in the lining of the blood vessels, deep breathing, nasal breathing activates that enzyme in the epithelial cells of our sinuses.

And so when we do nasal breathing, it's activating the enzyme to make nitric oxide. And now we're delivering that nitric oxide gas into the bronchioles, the lower airway. It's dilating those bronchioles. Moreover, it's dilating the pulmonary arteries. So now we're improving oxygen uptake, oxygen delivery. And that's why nasal breathing and deep breathing has been shown to lower blood pressure.

Oh, yeah, again, going over the past 20 years. Yeah, no, I think there's a lot of people. I mean, obviously your girlfriend, there's Patrick McKeown in the UK.

Yeah. Now, I think the benefits of that are pretty well, and mechanistically we understand the benefits of it. So the mouth breathers are not only bypassing this natural nitric oxide production pathway, but when you mouth breathe, it completely changes the microbiome.

And so you're not only bypassing the nitric oxide producing in the upper airway, but you're inhibiting nitric oxide production in the mouth from the microbiome because you're fully oxygenating the mouth. It's changing the pH of the saliva and completely changes the microbiome and completely shuts down nitric oxide production.

So you have to, I mean, I'm a big fan of mouth taping. But for me, I know, and I watch my kids, but sometimes there's anatomical issues where there's obstructive airways and airway obstruction that has to be corrected by dental appliances or sometimes surgery. But the worst thing you can do is tape your mouth and your airway be constricted and, you know, you suffocate. Yeah.

So before you do mouth taping, you need to get some imaging done from your dentist to make sure that your airway is open to where if you're forced to breathe through your nose, you can actually have oxygen exchange.

Humming, you know, there are certain frequencies. We've done this in looking at nitric oxide coming out of the exhaled breath when you're humming. So certain frequencies can activate this enzyme. And it's dependent upon the volume of the nasal sinuses. So there's not one frequency that would work in every single person.

Because the volume of your airways and oral cavity and sinuses was probably much different than mine.
