As the world becomes increasingly health-conscious, wearable devices like the Apple Watch have become an essential tool for monitoring our well-being. One feature that has garnered significant attention is the ability to track oxygen levels. But does the Apple Watch really track oxygen levels, and if so, how accurate is it? In this article, we’ll delve into the details of this feature, exploring its capabilities, limitations, and what it means for your health.
Understanding Blood Oxygen Levels
Before we dive into the Apple Watch’s oxygen-tracking feature, it’s essential to understand the importance of blood oxygen levels. Blood oxygen levels, also known as oxygen saturation, refer to the percentage of hemoglobin in your blood that’s carrying oxygen. This measurement is crucial, as it indicates how well your body is transporting oxygen to your organs and tissues.
A normal blood oxygen level is typically between 95% and 100%. Levels below 90% can indicate a potential health issue, such as respiratory or cardiovascular problems. In severe cases, low blood oxygen levels can lead to hypoxemia, a condition that can cause symptoms like shortness of breath, fatigue, and confusion.
How Does the Apple Watch Track Oxygen Levels?
The Apple Watch Series 6 and later models come equipped with a built-in blood oxygen sensor. This sensor uses a technology called pulse oximetry to measure the oxygen levels in your blood. Pulse oximetry works by emitting red and infrared light through your skin, which is then absorbed by the hemoglobin in your blood. The amount of light absorbed is directly related to the oxygen levels in your blood.
The Apple Watch’s blood oxygen sensor is located on the back of the device, and it takes readings periodically throughout the day. You can also take on-demand readings by opening the Blood Oxygen app on your Apple Watch.
How Accurate is the Apple Watch’s Oxygen Tracking Feature?
The accuracy of the Apple Watch’s oxygen tracking feature has been a topic of debate. While Apple claims that the feature is accurate, some studies have raised concerns about its reliability.
A study published in the Journal of Medical Engineering & Technology found that the Apple Watch’s blood oxygen sensor was accurate in 80% of cases. However, the study also noted that the device was less accurate in individuals with darker skin tones or those who had cold hands.
Another study published in the Journal of Clinical Monitoring and Computing found that the Apple Watch’s oxygen tracking feature was less accurate than a traditional pulse oximeter. The study concluded that while the Apple Watch was able to detect changes in oxygen levels, it was not accurate enough to be used as a medical device.
Limitations of the Apple Watch’s Oxygen Tracking Feature
While the Apple Watch’s oxygen tracking feature can be a useful tool for monitoring your health, it’s essential to understand its limitations.
- Skin tone: As mentioned earlier, the Apple Watch’s blood oxygen sensor may be less accurate in individuals with darker skin tones.
- Cold hands: Cold hands can affect the accuracy of the readings, as the device relies on blood flow to take measurements.
- Tattoos: Tattoos on the wrist can also affect the accuracy of the readings, as the ink can absorb some of the light emitted by the sensor.
- Movement: Movement can also affect the accuracy of the readings, as it can cause the sensor to take incorrect measurements.
What Does the Apple Watch’s Oxygen Tracking Feature Mean for Your Health?
While the Apple Watch’s oxygen tracking feature is not a medical device, it can still provide valuable insights into your health. Here are a few ways that the feature can benefit your health:
- Monitoring respiratory health: The Apple Watch’s oxygen tracking feature can help you monitor your respiratory health, which is essential for individuals with conditions like asthma or COPD.
- Detecting sleep apnea: The feature can also help detect sleep apnea, a condition that causes pauses in breathing during sleep.
- Tracking altitude changes: The Apple Watch’s oxygen tracking feature can also help you track changes in altitude, which can be essential for individuals who engage in high-altitude activities like hiking or skiing.
How to Use the Apple Watch’s Oxygen Tracking Feature Effectively
To get the most out of the Apple Watch’s oxygen tracking feature, follow these tips:
- Take regular readings: Take regular readings throughout the day to get a better understanding of your oxygen levels.
- Monitor changes: Monitor changes in your oxygen levels over time, as this can indicate a potential health issue.
- Consult a doctor: If you notice any significant changes in your oxygen levels, consult a doctor to rule out any underlying health issues.
Conclusion
The Apple Watch’s oxygen tracking feature is a valuable tool for monitoring your health, but it’s essential to understand its limitations. While the feature is not a medical device, it can still provide valuable insights into your respiratory health and detect potential health issues. By understanding how the feature works and its limitations, you can use it effectively to take control of your health.
Remember, the Apple Watch’s oxygen tracking feature is just one tool in your health monitoring arsenal. Always consult a doctor if you have any concerns about your health, and never rely solely on the Apple Watch for medical diagnosis or treatment.

Does Apple Watch track oxygen levels?
The Apple Watch Series 6 and later models are equipped with a built-in blood oxygen sensor that allows users to measure their oxygen levels. This feature is made possible by the watch’s ability to use light to measure the amount of oxygen in the blood. The sensor emits red and infrared light through the skin, and the amount of light absorbed by the blood is used to calculate oxygen levels.
It’s essential to note that the Apple Watch is not a medical device, and its oxygen level readings should not be used for medical diagnosis or treatment. The feature is intended for general wellness and fitness tracking purposes only. If you have concerns about your oxygen levels or overall health, consult a medical professional for proper evaluation and advice.
How accurate is the Apple Watch’s oxygen level tracking feature?
The accuracy of the Apple Watch’s oxygen level tracking feature has been a topic of discussion among users and experts. According to Apple, the feature is designed to provide an estimate of oxygen levels in the blood, with an accuracy of ±2% under ideal conditions. However, various factors, such as skin type, tattoos, and cold temperatures, can affect the accuracy of the readings.
Studies have shown that the Apple Watch’s oxygen level tracking feature can be reliable in healthy individuals, but its accuracy may be reduced in people with certain medical conditions, such as anemia or chronic obstructive pulmonary disease (COPD). It’s crucial to understand the limitations of the feature and not rely solely on the Apple Watch for medical diagnosis or treatment.
How do I measure my oxygen levels with the Apple Watch?
To measure your oxygen levels with the Apple Watch, make sure you’re wearing the watch correctly, with the sensor in contact with your skin.
