Not seeing detailed sleep data in the Health app

Here's a screenshot of all I see in the Health app.

No details about the kind of sleep, just hours.

OK, I've done that and will see if that helps.

Actually, maybe I need to back up a second. I'm trying to find confirmation, but does the Health app display the advanced data about sleep (e.g., REM percentage, deep sleep percentage, etc.)? Or do only 3rd party apps show those details? I haven't found anything on the Web about seeing the detailed sleep analysis in Health app. I thought I saw it in the past when I first got my watch a few years ago.

Just read this:

"Notably, the Sleep app does not give you a sleep score, like wearables from Fitbit, Amazon, and Garmin do. Nor does the Sleep app offer numbers for average heart rate during sleep, sleep stages, or average sleep respiration. In contrast, the Fitbit Charge 3, Amazon Halo, and Garmin Vivoactive 4S track sleep stages, like light, deep, and REM sleep. The Fitbit Charge 3 can track naps, not just night sleep, and Amazon’s new Halo wearable tracks skin temperature while sleeping."

Thanks for the reply.

I'm under the impression that the Sleep app on the Watch automatically enters the data into the Health app. However, I've also let the Pillow and REM apps share the sleep data from the watch to the Health app.

Yes, my Apple Watch is listed at the top of Data Sources & Access for Sleep. Beneath it are my iPhone then the 3rd party sleep apps.

If I then click on my Apple Watch data source, it shows me the data sets broken out into different times during the night.

Thanks. Are you saying I'd need to "turn off" the 3rd party apps in order to get the detailed sleep data into Health?

Sorry, confused. I have already given the 3rd party apps permission to enter their data into the Health app.
