If you have an Apple Watch on your wrist or have played around with the popular smartwatch before, odds are you're familiar with how much technology is packed into this small device. Even longtime Apple Watch fans may not be familiar with some of its health features, and those features could help better support a wellness journey.
To learn more about the hidden health features on the Apple Watch, I reached out to Dr. Lauren Cheung, a doctor at Apple, who explained these tools and why they were created for those with Apple devices.

1. The Vitals app
Using overnight health metrics, the Vitals app can reveal much about your health and how it changes daily. From heart rate and wrist temperature (available on Apple Watch Series 8 or later and any Apple Watch Ultra model) to respiratory rate and sleep duration, you can get a thorough picture of your health from just one glance at your watch. If you purchased an Apple Watch sold in the US before Jan. 18, 2024, you may also be able to measure your blood oxygen.
"When two or more of your metrics are out of range, we will notify you with information about why that might be," Cheung told me in an email. "How it works is just after you wake up, you might see a notification from the Vitals app. For example, maybe your heart rate and wrist temperature were high -- this could be due to illness or alcohol consumption."
With the health information provided by the Vitals app, you can make informed decisions about your body. If specific metrics are outside your normal range, you can choose to get extra rest that day or visit your doctor if you have particular symptoms.
How to set up the Vitals app
To set up your typical range, you must wear your Apple Watch for at least seven days. Ensure your watch is not loose on your wrist; otherwise, it might not capture accurate readings.
To set up notifications, go to Settings on your Apple Watch, tap Vitals and turn on notifications.
