(Pocket-lint) – When Apple launched the Apple Watch in 2015, sleep tracking wasn’t offered. It wasn’t until 2020 with the arrival of watchOS 7 that the feature appeared, albeit in a more basic form than rivals like Fitbit and Garmin.

With the arrival of watchOS 9, however, the Apple Watch finally offers somewhat more substantial sleep tracking. There are now stages of sleep, with a breakdown of time awake, time in REM, time in deep sleep and time in deep sleep.

To be able to track your sleep with the Apple Watch, you need to put your device into sleep mode. It’s then a little tricky to find the data once it’s collected, but don’t worry, we’ve got you covered.


Here’s how to read and find sleep data from your Apple Watch.

How to View Apple Watch Sleep Data on iPhone

You can read and view sleep data from your Apple Watch either on the watch itself or on your iPhone. In the latter case, follow the steps below:

  1. Open the Health app on your iPhone
  2. Click on the Browse tab at the bottom right
  3. Scroll down to Sleep
  4. Tap D, W, M or 6M to view your sleep data by day, week, month or 6 months.
  5. Tap “Show more sleep data” below the sleep graph to view the time spent at each stage.

How to check sleep data on your Apple Watch

It’s possible to see your sleep data on your Apple Watch, but you won’t be able to see as much detail as with your iPhone. You will only be able to see data for the previous night and not for an entire week or month, for example.

To read your sleep data on Apple Watch, follow these instructions:

  1. Open the Sleep app on your Apple Watch
  2. Scroll down to Analysis
  3. You’ll see a graph, along with time falling asleep and time in sleep stages.
  4. Scroll down to see a bar chart for the last 14 days, with a line indicating the average time you fell asleep.

How accurate is Apple Watch sleep data?

In our testing, we found the Apple Watch Series 8’s sleep data to be about what we expected in terms of falling asleep and waking times.

Understandably, it’s difficult to determine the accuracy of the steps, although REM sleep is known to be when you dream and we found the data presented seemed to be consistent with what we would have experienced if we had woken up from a dream. .

We’ve devoted an entire article to sleep tracking and what that data means. In summary, your body enters and exits four stages over the course of a night: awake, light, deep, and paradoxical.

He needs a combination of all of these stages to recover, rebuild, and wake up feeling rested. Light sleep is said to enhance memory and learning, deep sleep promotes physical recovery, and REM sleep promotes strategic thinking and creativity.
