Past that, it's way more interesting stuff than sleep staging.

Sleep staging is...

is not a good way at all to think about sleep quality.

More interesting are things like fragmentation, sleep stability, sleep range.

The amount of time you spend in those arbitrary sleep stages varies wildly by cognitive demand.

Your body is not asked to do the same things on every day, so it's not gonna have the same sleep architecture every day.

So the way that we define high quality sleep, completely different.

What we are working on right now, actually,

is direct testing of next day cognitive function.

That's how we backfill sleep quality and sleep timing.

And so we want to actually develop methodologies in which we're like, we'll actually test a whole bunch of different cognitive functions and we can determine what is actually effective for you based on your actual functionality rather than an arbitrary like set of numbers.

If that is like, what the hell is he talking about?

Back all the way up and just say, how do you define good quality sleep for you?

How is your daytime function?

That is your thing.

Are you fatigued?

Are you sleepy throughout the day?

Everyone's gonna be somewhat sleepy, particularly in the afternoon, right?

But is it detrimental to your performance?

How are you performing cognitively?
