I am doubling down on regularity.

It's so important.

That tells us, I think, something that is, in some ways, a story not about sleep.

It's a story about your circadian rhythm.

We speak a lot, or I speak a lot, about sleep, and I think I've probably done a missed service

to the other aspect of the sleep-wake rhythmicity, which is called your 24-hour circadian rhythm.

Now, your sleep pressure, the drive to sleep is independent of your circadian rhythm, but they often work beautifully in harmony with each other and you fall asleep and you stay asleep.

But I think the circadian system is critical because, excuse me,

And what the Scadian rhythm also regulates sneezing right at the inopportune moment when you're recording a podcast.

But nevertheless, what that tells me is that when you feed your brain signals of wake-sleep consistency, which is to say wake-sleep timing regularity,

There is something about feeding the brain signals of regularity that anchor your 24-hour circadian rhythm.

And as a consequence, it improves the quantity and the quality of your sleep.

They're intertwined.

Oh, gosh, it's such a wonderful question.

And as with wonderful questions, the answer is usually yes.

It's complicated.

And I have to be careful because, you know, for someone who's currently wearing three different sleep trackers, it's going to be hard for me to answer this question completely in the negatives.

And there are three different sleep trackers.

But I would say that for the most part, I like the idea of sleep tracking if you're sleeping well.

meaning as long as you're not suffering from insomnia.
