To be able to adjust to new time zone.

And sometimes you need to sleep at different times to adjust to new time zone.

But if you're not tired or you're tired when you should be awake to adjust, then your whole circadian sleep cycles gets run off with the new time zone you're going to.

And so Apollo can help you get extra sleep on the plane or stay awake longer without having to take drugs so that you can actually adjust to the new times and more easily without so much jarring.

Yeah, it's been a game changer for travel for me.

Generally speaking, yeah.

I mean, we usually think of...

trying to get at least six hours a night.

But I think in the cases where people are getting a substantial amount of deep and REM in that way, like 90 minutes of each, that's pretty good.

I've seen Naveen.

He's usually feeling pretty good.

He looks good for his age.

I mean, I think that's more important.

If you have to prioritize one thing, it's how much deep and REM sleep you're getting.

Total sleep time is less important.

Yeah, so HRV is such an interesting biomarker right now.

And it's easily one of the most important biomarkers of mental and overall physical health and performance that we have because studies have shown in the last 10 years that if you have a higher heart rate variability, which is the rate of change of your heartbeat over time, that you're more adaptable.

So effectively, high heart rate variability means when stress comes, your heartbeat goes up quickly.

You adapt to it.

You meet the stress head on, and then the stress is gone, and then your heartbeat comes down quickly.
