The worst still, you can then go and tap at any moment in your night and you can listen to yourself gasping for breath and snoring. Because snoring, what happens when you snore is that the airway starts to partially collapse. And when it starts to partially collapse, like a straw that gets bent, sort of, you start to get these fluctuations, these eddies in the airway. And that's the sound of...

That's the partial collapsing of the airway. When the airway collapses completely, the straw goes flat effectively. That's when you stop breathing entirely. And you can be there for 15, 20 seconds, and your blood oxygen saturation just starts to plummet.

And at some point, your brainstem, which picks up the ratio of the gases in your bloodstream between carbon dioxide and oxygen, says, break glass in case of emergency. Wake him up. We've got to wake him up. And that's the moment where you hear, and you gasp and you're back up again. As a consequence, you're never going into deep sleep. You stay in those shallows of sleep.

Now, mild sleep apnea, if you have these, what we call apnea events, and apnea is a word, it's beautiful. Pnea is breath from a Latin derivative. Anything in medicine that has the word A before it is usually the absence of it. You know, arrhythmia, the absence of a normal rhythmic heart. Apnea is the absence of breath. And mild sleep apnea is you having maybe five to 15 of the events per hour.

That's how we grade it. For each hour of sleep, how many of these events are you having? Mild sleep apnea, let's just call it 10 events. And you're asleep for eight hours.

Imagine if I were to come in and say, tonight, Chris, I'm going to come into your room and for the entire night, maybe 80 times throughout the night, I'm going to come in and I'm going to throttle you around your throat to the point where your oxygen saturation drops below 80%. Do you think you're going to feel good by tomorrow morning? The answer is no.

But so many people are living with undiagnosed sleep apnea. We think at least 80% of people who have sleep apnea are undiagnosed right now. And that will put you in an early grave.
