Apple Watch has become a powerful tool for health tracking, offering features like heart rate monitoring, blood oxygen levels, and sleep tracking. One of its lesser-known but equally important features is respiratory rate tracking. This feature provides insights into how often a person breathes per minute while sleeping, which can help monitor overall health and detect potential issues early.
This guide explains how Apple Watch measures respiratory rate, where to find the data, why it matters, and how to improve respiratory health.
What Is Respiratory Rate?
Respiratory rate refers to the number of breaths a person takes per minute. It is a key vital sign used to assess lung function and overall health. A normal respiratory rate for adults typically ranges between 12 and 20 breaths per minute. If breathing patterns change significantly, it may indicate stress, illness, or other medical conditions.
Apple Watch records respiratory rate while a person is sleeping, helping to provide consistent data without external distractions.
How Does Apple Watch Measure Respiratory Rate?
Apple Watch does not have a built-in sensor specifically designed for tracking respiration, but it uses the device’s accelerometer and motion sensors to detect subtle chest movements associated with breathing. These movements are tracked during sleep and processed through the Sleep app and the Health app on an iPhone.
The respiratory rate tracking feature is available on Apple Watch Series 3 and later models running watchOS 8 or newer.
How to Enable Respiratory Rate Tracking on Apple Watch
To start recording respiratory rate, sleep tracking must be enabled on Apple Watch.
Steps to Set Up Sleep Tracking and Respiratory Rate Monitoring
- Open the Health app on an iPhone.
- Tap Browse at the bottom of the screen.
- Select Sleep and then tap Set Up Sleep.
- Follow the instructions to create a sleep schedule.
- Make sure Track Sleep with Apple Watch is enabled.
Once sleep tracking is enabled, the Apple Watch will automatically record respiratory rate when worn during sleep.
How to Check Respiratory Rate on Apple Watch and iPhone
Apple Watch records respiratory rate data overnight, but it must be reviewed through the Health app on an iPhone.
Steps to View Respiratory Rate Data
- Open the Health app on an iPhone.
- Tap Browse at the bottom of the screen.
- Select Respiratory and then tap Respiratory Rate.
- View recorded data in daily, weekly, and monthly trends.

Why is respiratory rate important?
Tracking respiratory rate can provide valuable health insights.
Detecting Sleep-Related Issues
Respiratory rate tracking can help identify irregular breathing patterns that may indicate sleep disorders such as sleep apnea. While Apple Watch does not diagnose medical conditions, significant fluctuations in respiratory rate could be a sign that further evaluation is needed.
Monitoring Fitness and Recovery
Athletes and fitness enthusiasts can use respiratory rate data to monitor recovery and performance. A lower respiratory rate may indicate improved cardiovascular fitness, while an increase could suggest fatigue or stress.
Identifying Signs of Illness
Changes in respiratory rate can be an early indicator of illness, including respiratory infections or conditions such as asthma. A consistently high respiratory rate during sleep could be a sign of an underlying health issue.
Factors That Affect Respiratory Rate Measurements
Several factors can influence respiratory rate, leading to variations in Apple Watch readings.
- Physical activity: intense exercise before sleep may temporarily increase respiratory rate.
- Stress and anxiety: High stress levels can lead to faster breathing, even during sleep.
- Altitude and air quality: Higher elevations or poor air conditions may affect breathing patterns.
- Sleep position: Certain sleeping positions may cause temporary variations in respiratory rate.
How to Improve Respiratory Health
Maintaining a healthy respiratory rate is important for overall well-being. Here are a few ways to improve respiratory health.
Practice Deep Breathing Exercises
Deep breathing techniques, such as diaphragmatic breathing, can improve lung function and reduce stress.
Stay Active with Regular Exercise
Cardiovascular activities like running, swimming, and cycling help strengthen the lungs and improve overall endurance.
Improve Sleep Quality
Maintaining a consistent sleep schedule, sleeping in a cool, dark room, and avoiding stimulants before bed can help support healthy breathing patterns during sleep.
Monitor Respiratory Trends in the Health App
Regularly reviewing respiratory rate data can help detect trends and potential health concerns. If significant changes occur, consulting a healthcare professional may be beneficial.
Limitations of Apple Watch Respiratory Rate Tracking
While Apple Watch provides useful respiratory rate data, there are some limitations.
- It only records respiratory rate during sleep, not throughout the day.
- Measurements are based on motion detection, which may not be as accurate as medical-grade respiratory monitors.
- It does not provide real-time feedback or alerts for abnormal breathing patterns.
Future Improvements for Respiratory Rate Tracking
As Apple continues to develop health-tracking features, future updates may improve respiratory rate monitoring. Potential enhancements could include:
- Real-time respiratory rate tracking during workouts or throughout the day.
- Integration with stress and mindfulness apps for personalized breathing exercises.
- Alerts for significant changes in breathing patterns.
Comparing Apple Watch to Other Respiratory Tracking Devices
Several other devices offer respiratory rate tracking, including medical wearables and dedicated fitness monitors. Devices such as Fitbit and Garmin smartwatches also provide respiratory rate tracking, but Apple Watch focuses more on overnight measurements rather than real-time monitoring.
