Use Daytime Heart Rate

This article introduces an exciting and versatile feature to your Oura experience: Daytime Heart Rate—your newest tool for monitoring your body 24 hours a day.

Daytime Heart Rate is available for both iOS and Android on the Oura Ring Gen3 only.

Here’s what we'll cover below:

• The Three Elements

• How It Works

• Get Started

• Things to Keep in Mind

What is Daytime Heart Rate?

Oura can now track your heart rate 24/7, revealing periods of relaxation, exertion, and stability throughout your day and night. Daytime heart rate accounts for all variation in your body signals over a 24-hour period and reflects them back to you with different colors. For the first time ever, you can quickly identify which events and activities your heart rate has registered, regardless if you’re asleep or awake.

We’ve also introduced the ability to compare your personal sleeping and daytime heart rate patterns with well-respected heart rate trends in the field of human health. This is designed to help you quickly interpret your data. See ‘How it Works’ to learn more.

The Three Elements

You can think of Daytime Heart Rate as a suite of three interconnected components:

24/7 heart rate tracking and trendline

Oura gives you the full scope view—we’re still prioritizing your nighttime heart rate trends, but with daytime added, you can now get the full picture of how your body is constantly responding and adapting on a 24-hour basis. Keep in mind, your nighttime heart rate trends are still accessible in your Sleep Icon_Moon.png and Readiness Icon_Readiness.png tabs in addition to your Daytime HR card in Home Icon_Home.png.

Live Heart Rate

Oura lets you check in with your body at any given moment. See your heart rate in real-time animation. Check out our article here to get the full details on Live Heart Rate.

Restorative Time

We’re extending our best-in-class sleep and recovery measurements to your waking hours with Restorative Time, which helps you see when your body has been relaxed throughout each day. Check out our article, An Introduction to Restorative Time, for a thorough explanation of how to get the most out of this powerful asset.

How Daytime Heart Rate Works

Oura takes measurements of your daytime heart rate every 5 minutes using the green LEDs tucked away in your Gen3 ring. To preserve battery and maximize accuracy, a heart rate measurement will only be taken if Oura detects optimal conditions—including low movement and balanced body temperature. Low movement can consist of working at your desk, standing, and sitting in a chair or at a table, for example. You do not, however, need to be entirely still. If your skin temperature is too low, Oura may struggle to give you an accurate heart rate measurement—but anytime you’re indoors or properly dressed in outdoor conditions, this is very unlikely to be the case.

Once your ring has detected the right conditions are in place, Oura will measure your heart rate for 1 full minute. All finalized, 1-minute heart rate readings will be incorporated into your Daytime HR graph and trendline. You’ll see your most recent heart rate as a value (in BPM—beats per minute) directly beneath your graph and trendline.

Keep in mind: due to our refined quality control to ensure you’re receiving the most accurate heart rate data possible while optimizing battery life, Oura will reflect meaningful heart rate values back to you over 75% of the time. This means you may not receive an updated heart rate incorporated into your Daytime HR graph and trendline, or shown as a value in BPM, for up to 30 minutes.

How to Use Daytime Heart Rate

Step 1: Onboard

If you’re just getting started with your new Gen3 ring and haven’t used Daytime HR yet, you’ll see an onboarding card for the feature in your Home Icon_Home.png tab. Scroll through to read brief descriptions of Daytime HR at large, as well as Restorative Time and Live HR, both of which are built from Oura’s new capacity to track your heart rate 24/7.

Step 2: Dive in!

After your first day, your 24/7 heart rate will be available as its own card in your Home Icon_Home.png tab, located beneath your Activity Goal Progress. From the Home view, you’ll see a snapshot of your heart rate patterns for the current day, beginning at midnight. Your most recent heart rate value (in BPM) will be displayed here. While you’re actively viewing your Daytime HR Home card, you’ll see your Live Heart Rate if it’s available at the moment. To learn more about how to use Live HR, please visit this article.

See things in detail

Tap anywhere on your Daytime HR Home card to see your full graph and trendline in expanded detail. The 24-hour timeline (x-axis) on the bottom of your graph represents time of day, and scales from midnight to midnight. The values shown vertically on the right-hand side of the graph (y-axis) represent your heart rate in BPM (beats per minute). From this detail view, you’ll also see your: (1) Restorative Time (sum of total minutes), (2) Sleeping HR range (lowest point to highest point), and (3) Daytime HR lowest average.

Some Daytime HR graph basics

Horizontally, each bar shown on your graph (regardless of color) represents a 30-minute time window. The range of heart rate measurements taken during every 30-minute window are what make up the vertical length of each bar. If you see breaks in the vertical segments, this means Oura picked up multiple heart rate ranges during that particular 30-minute window.

The solid white trendline moving from left to right across your graph represents the average between all incremental heart rate measurements picked up by Oura. Your sleeping ranges will be highlighted in blue, while any restorative ranges during your waking hours will be highlighted in green. All other daytime values will be shown in grey. 

If proper conditions are met, you can view your heart rate in live time, indicated by the flashing heart Icon_Moment_Onboarding_3__1_.png icon and its associated data point on your graph.

You can swipe to the left on your Daytime HR graph to view your 24-hour heart rate data from previous days.

An extra layer of granularity

By tapping anywhere on your graph where there’s data, you can unlock additional insight into each 30-minute time window. A thin, vertical blue line will appear, which you can hold and drag across each data segment to observe your exact heart rate range during that window and the time of day it was collected.

Tap on any of the 3 core metrics (Restorative Time, Sleeping, and Daytime) to visualize your data in the context of an expanded graph

Tap into Restorative Time to see a timeline that extends from the moment you woke up to midnight. Follow the green segments on this timeline to see which periods throughout the day you collected the most Restorative Time. Staying keen to when you’ve gathered majority of your restorative minutes can be helpful if you’re looking to understand at which times of day you let your body recover and unwind—versus, when you’re actively on the go or in an elevated state.

You can scroll down through the various examples shared for both sleeping and daytime heart rate while keeping your personal curve pinned at the top, allowing for easy comparison.

What if...my patterns don’t align with any of Oura’s heart rate curves?

Keep in mind, if you aren’t able to align your personal heart rate data with any of the examples shared, that’s perfectly okay! We don’t expect perfect alignment between your individualized trends and population norms. We suggest you try to find the example that most closely matches what you see in your graph and if you still come up short, we recommend you stay keen to your day-to-day patterns.

Whether or not they're represented by well-established norms, if you’re consistently experiencing the same patterns for your sleeping and daytime heart rate curves, that’s something to make note of. If you feel good, stick with it—if your patterns seem to vary on the daily and you experience fluctuations in your overall mood, attentiveness, and state of being, take note of this and consider exploring Tags & Trends. Using both Tags & Trends in tandem can help you identify which behaviors and actions may be influencing your sleep and recovery data patterns. 

Things to Keep in Mind

Daytime HR is not available on the Oura Ring Gen2 or our original ring generation. If you upgraded to Gen3 from a previous generation, Daytime HR values will not be reflected in any of your previous data collected on earlier generations.

Daytime Heart Rate is not the same as Workout Heart Rate, which is coming to your Gen3 ring at the end of 2021. If you exercise while wearing your ring and don’t record your heart rate using Workout HR, you’ll still see this reflected in your daytime graph; however, these data points won’t accurately reflect your true Workout HR and it may appear as a gap or break in your trendline. Once Workout HR is available on Gen3, if you record your heart rate during exercise with this feature, it’ll automatically be incorporated into your daytime graph alongside all other values (restorative, sleeping, daytime).

If due to excess movement or unusually low body temperature your Daytime Heart Rate isn’t available for a favorable measurement by Oura for an extended period of time, you’ll see a small gap in your data—indicated with a dotted line or empty space in your graph.

If you have a detected and confirmed nap, it’ll appear as sleep (in blue) on your 24-hour daytime graph.
