Last year, with the introduction of watchOS 7, Apple added the ability to track your sleep metrics using the Apple Watch. Now, with watchOS 8, you can also track your respiratory rate throughout the night, which could help to detect early signs of medical conditions like sleep apnea, and chronic lung disease, among others.
Using its built-in accelerometer, the Apple Watch can track the number of breaths you take per minute while asleep. The results are then recorded in the Health app, which also gives you deeper insight into the data on a daily, weekly, monthly, and yearly basis.
Here’s how to monitor your breathing rate while you sleep with Apple Watch.
First, let’s make sure your Apple Watch is compatible

At the top, the Respiratory Rate section includes a chart that shows your range of breaths per minute based on the hour, day, week, month, and year. Additional data and information on the topic will appear as you scroll down.
To see your breaths per minute while asleep, tap on “Show More Respiratory Rate Data.” At the bottom is a dedicated Sleep section that displays your specific number of breaths per minute.
As you continue to wear the Apple Watch to bed and monitor your breathing, the Health app will be able to identify more in-depth and useful trends over time.
