And just to remind you, you can get his entire sleep course finding your best sleep on the Headspace app right now. Hello, Hello, everyone. It's great

Thanks,

... Dr. Eric Prather here with some science-backed ways to help you sleep easier. Today we're talking about sleep trackers.

I'll tell you how effective they really are and what they can reveal about why we're not getting more restful sleep.

Let's get into it.

Whether it's a ring or a watch or a mattress, most of the consumer-based wearable devices

are pretty good at estimating total amount of sleep

that someone gets because they are good at detecting

wake versus sleep.

They're also pretty good at estimating

how fragmented someone's sleep is,

because if they're wearing them, they're moving around,

these devices generally are movement-based,

and then use different signal processes like heart rate and breathing rate to try to estimate

when someone's sleeping or not.

Sleep trackers are everywhere, and I love it because people are so interested in their sleep.

But it also can be problematic.

I think the thing that people often get really tied to

is the sleep architecture.

So this is, you know, whether someone's in deep sleep
