Because if it was that, and I do all the tips with you and I work out this and I do all this and you're still feeling like, oh, but my sleep just isn't good.

And I knew on day one that this was a possible reason why, then I'd feel like an idiot for not even checking.

Because we did all this work and maybe we didn't even need to.

So there's a bunch of devices.

They've gotten better and smaller over the years.

There's still people who do need to come into the lab.

Those are usually reserved for

When there's like another sleep disorder, you're also looking for like narcolepsy or limb movements or something.

Or if you're medically complicated, like you need supplemental oxygen or if you might have heart failure or something where you need to kind of be monitored in the hospital while you're doing it for safety.

Other than that, or the test you did at home was negative, but you still have a lot of symptoms and maybe it missed it because the home tests aren't as sensitive.

Like you won't get false pauses, but you might get false negatives.

That's the only time you'd really need to come into the lab most of the time.

Usually they just give you the thing to take home.

And these days you can wear it as a strap.

They have ones that just go on your wrist and they measure your oxygen levels during the night.

And what you can see is

How is your respiration tied with your O2?

Because respiration drops during the night too.

And so does O2 a little bit.

But if your respiration is dropping and then your O2 starts dipping and then it opens back up again and gets recovered, like you look at these patterns of what's happening during the night and you can see in one night if someone's clearly has sleep apnea or not.
