Health Radar brings together key cardiovascular, respiratory, and strain signals in one central dashboard, so you can spot meaningful changes in your health patterns over time.

Health Radar is gradually rolling out starting June 16, 2026 to eligible members in the US, India, and United Arab Emirates:

• Gen3 or later with active membership
• iOS
• Android

This feature is not available on Gen2 or older.

This feature is currently only available in English. If you'd like to use it, try setting your phone language to English.

How Health Radar Works

Health Radar monitors your long-term heart and breathing patterns, as well as shorter-term signs of strain. It’s designed to help you notice meaningful changes early and let you know when speaking with a healthcare professional might be a good idea. Any patterns worth your attention will show up in the Today tab. When Health Radar detects a risk signal, it can cap the rating in the related My Health domain (e.g., Heart Health).

Health Radar is tailored to you based on your height, weight, and sex assigned at birth. Make sure your profile is up to date to get the most accurate results.

You'll find Health Radar in the My Health tab and in the   menu.

Health Radar does not diagnose or monitor any conditions, or replace medical care. Guidance from your healthcare professional always comes first, especially if you're pregnant or have existing health conditions. 

Finding and Managing Health Radar

You'll find Health Radar  the My Health tab and in the (≡) menu.

When you first set up Health Radar, all features are automatically turned on. You can tap into the features and toggle and or all off at any time.

• If you opt out of all Health Radar features, it will stop actively monitoring your data and your My Health ratings will no longer be affected by Health Radar signals.
• If you turn off Blood Pressure Signals, any past data will be hidden and your assessment will be turned off. The 30-day assessment period will restart when you turn the feature back on

Health Radar: Short-Term Strain

Symptom Radar

Symptom Radar looks for day-to-day shifts that might signal your body is under some extra strain, so you can balance your day with rest and recovery when you need it.

How it Works

Symptom Radar monitors several biometrics including average body temperature, respiratory rate, resting heart rate, heart rate variability. The estimate is based on a unique combination of all your biometrics over time. Changes in your biometrics are detected during sleep, and when your sleep data is available, you’ll get an estimate in the morning in the Today tab if you have signs of something straining your body. You need at least seven nights of sleep data within the past 14 days.

Signs of strain are shown in a three-level estimate:

• No signs: There are no obvious signs in your biometrics of something straining your body
• Minor signs: There are small signs in your biometrics of something straining your body
• Major signs: There are stronger signs in your biometrics of something straining your body

If there are minor or major signs of strain, the Oura App will recommend focusing on rest and recovery and will display the biometrics that are showing the most change. If needed, you can enable Rest Mode, which pauses your Activity Score, goal, and all activity contributors. Symptom Radar will continue to monitor your metrics even with Rest Mode activated.

Troubleshooting

If you see Calibrating or Missing Sleep Data:

• Keep wearing your ring at night to help the feature gather enough data. Symptom Radar requires at least seven nights of sleep data from the past 14 days (including last night) to display a reading.

If you see Insufficient Sleep Data:

• This means your ring was worn, but something disrupted the data collection. Your ring might have been too loose, or your sleeping position may have restricted blood flow (like if your arm went numb). Try wearing your ring on a different finger for a snugger fit and adjusting your sleep position to support better data collection

If you see Calculating for an extended period:

• Double-check that your profile details are complete and accurate. To review your details, go to the (≡) menu and select My Profile

Things to Keep in Mind

• Symptom Radar looks for early signs of common respiratory illnesses—like a cold or the flu—based on changes in your biometric data. While it’s designed to give you a heads-up before symptoms appear, it’s not always perfect. You may receive a warning even if you feel fine or feel unwell without seeing a warning.
• Everyone's body responds differently to strain or illness. If you're unsure, trust how you feel, and use Rest Mode when you need it
• Readiness and Symptom Radar use some of the same data, but they serve different purposes, so their results won’t always match. Readiness Score can remain high even when there are signs of something straining your body. When your body starts to respond to strain or high activity levels, your Readiness Score doesn’t always decrease immediately. 
• Symptom Radar may not work optimally with pre-existing medical conditions
• Pregnancy also impacts biometric baselines and may reduce the accuracy of Symptom Radar

Health Radar: Long-Term Patterns

Nighttime Breathing

Nighttime Breathing is a wellness feature that shows a 30-day view of how frequently breathing disruptions occur during sleep, based on signals from the ring.

How it Works

Nighttime Breathing tracks the steadiness of your breathing across each 30-day window. After seven days of data, you’ll be able to see your prevailing pattern for the ongoing period. 

At the end of each 30-day period, you’ll be notified in the Today tab if your breathing has shown a notably varied pattern on several nights. You can turn off these notifications anytime from the Nighttime Breathing view.

You can find Nighttime Breathing in the Sleep detail screen and the Sleep Health Hub.

What your pattern means:

• Steady: Few or no breathing disturbances detected. This can indicate that your body is recovering well overnight.
• Mostly steady: You've experienced occasional breathing disturbances during sleep. This is common and generally not a cause for concern.
• Varied: This can suggest that you've experienced breathing disturbances on several nights. Lifestyle factors or a recent illness can sometimes contribute to this. If you've noticed daytime fatigue, morning headaches, or snoring, it may be worth discussing with your healthcare professional.
• Highly varied: This can suggest that you've experienced a higher number of breathing disturbances on many nights. This is worth paying attention to, especially if you've noticed daytime fatigue, morning headaches, or snoring. Consider reaching out to a healthcare professional to discuss what this pattern might mean for you.

Associated Factors

In the detail view, you’ll also see trends for factors like age, sex assigned at birth, weight, activity, sleep regularity, and average sleep duration. These aren’t direct inputs to the Nighttime Breathing algorithm, but they may help explain the patterns you’re seeing.

Connected Care: ResMed (US only)

US members who see elevated Nighttime Breathing patterns may be guided toward ResMed, Oura’s Connected Care partner for sleep breathing. ResMed can help you explore next steps, including a short assessment and care options to support healthy sleep.

Nighttime Breathing does not diagnose or monitor any conditions, and is not a replacement for medical care. If your pattern gives you pause, know that breathing disturbances during sleep are common — and a conversation with your healthcare professional is always a good place to start.

Blood Pressure Signals

Blood Pressure Signals is a wellness feature that monitors patterns in your nighttime PPG data over 30 days to detect blood pressure related patterns. This feature does not measure actual blood pressure in mmHg. It analyzes patterns in nighttime PPG signals; it does not measure or display blood pressure values.

Note: Blood Pressure Signals is auto-disabled for members using Pregnancy Insights.

How it Works

Blood Pressure Signals uses a 30-day assessment window to look for patterns in your data. You’ll only be notified in the Today tab if a pattern worth your attention is detected. When no patterns are detected, the feature stays in a neutral “actively monitoring” state with no result displayed. At least 15 nights of data are needed to build your baseline.

If your Blood Pressure Signals result differs from your doctor's assessment, that's expected, as they're measuring different things in different ways. Always follow your healthcare provider's guidance, and share any concerns with them directly.

Associated Factors

In the detail view, you’ll see trends for associated factors like resting heart rate, activity, and sleep duration. These aren’t direct inputs to the algorithm, but may help provide context for what you’re seeing.

Cuff Readings

Cuff Readings is a personal log where you can record blood pressure cuff readings, either by entering them manually or importing from Apple Health or Health Connect by Android. We recommend using a validated upper-arm cuff for the most accurate readings.

If you’re using Pregnancy Insights, you’ll see a customized cuff input experience.

Logged readings are labeled using American Heart Association ranges (Normal, Elevated, or High). Your readings are available to Advisor as reference context when you chat, but they don’t impact Blood Pressure Signals, Nighttime BP, or any Oura score.

A single reading is just a snapshot. For the most useful picture, take readings regularly, and talk to your healthcare professional if anything concerns you.

You can find Cuff Readings in the Heart Health Hub, and logged readings are also in both the Blood Pressure Signals and Nighttime BP screens.

Blood pressure and pregnancy

There are important differences in how blood pressure is evaluated during pregnancy, particularly from around week 20 through the first 12 weeks after delivery. If you measure your blood pressure at home and either the top (systolic) number is above 140, or the bottom (diastolic) number is above 90, this may be a sign of complications, so we recommend you contact your doctor.

Connected Care: Counsel Health (US only)

Counsel is gradually rolling out to US members in Oura Labs starting June 16, 2026.

Counsel Health is an AI-assisted medical guidance service available in Oura Labs for US members. It’s accessible from the Blood Pressure Signals result screen and the Health Radar hub, and allows you to have in-depth health conversations with an AI doctor who can see your ring data and records. See more in Oura Labs.

Keep in Mind

Blood Pressure Signals cannot diagnose or rule out any condition. This feature is for wellness use only. If you’re pregnant or managing a heart condition, this feature may not be right for you. Always confirm patterns with a blood pressure cuff and talk with a healthcare provider if you have concerns.
