Track your overnight vitals with Apple Watch

Review your health data with the Vitals app on Apple Watch to get a better understanding of your daily health status.

About the Vitals app

The Vitals app shows you what your typical overnight metrics are so you can assess them at a glance.¹ When you wear your Apple Watch to bed, the Vitals app estimates certain overnight health metrics and establishes a typical range for each. These metrics include:

• Heart Rate

• Respiratory Rate

• Blood Oxygen²

• Wrist Temperature³

• Sleep Duration

Factors such as your medications, elevation, alcohol intake or even illness can impact your metrics. If multiple metrics are outside of your typical range, you get a notification the next morning telling you the factors that may have caused the outliers.

Here’s what you’ll need

• An iPhone with the latest version of iOS.

• An Apple Watch with the latest version of watchOS.

• Sleep must be set up with Track Sleep with Apple Watch and Sleep Focus enabled.

• Wear your Apple Watch to sleep for 7 days to establish your typical range.

• Make sure that you're wearing your Apple Watch at a comfortable fit. If your watch is too loose, the sensors may not capture accurate readings.
