The Apple Watch measures your heart rate using photoplethysmography (PPG) and green LED lights, combined. The green LEDs shine through skin and blood vessels while the PPG sensor detects how much light is absorbed by blood. This information is then used to calculate your pulse.
The PPG sensor in the Apple Watch is remarkably advanced and accurate, capable of detecting even minute changes in blood volume. This enables it to precisely track your heart rate even during intense exercise or other physical activities.
Why Apple Watch Heart Rate Measurements Are Accurate
One of the primary reasons Apple Watch heart rate measurements are so accurate is due to its PPG sensor. This sensor can detect even minute changes in blood volume, enabling it to precisely track your pulse even during intense physical activity.
One factor contributing to the accuracy of Apple Watch heart rate measurements is how tightly the watch fits against your wrist. This ensures that its PPG sensor stays close to your skin, making it easier for it to detect changes in blood volume – leading to more precise readings of heart rate.
Furthermore, the Apple Watch is equipped with an advanced algorithm designed to filter out noise and interference from external factors like movement and ambient light. This ensures that even in brightly lit environments or when moving around a lot, your wrist watch will still accurately track your heart rate.
Conclusion
In conclusion, the Apple Watch is one of the most accurate and dependable fitness trackers available today. Its advanced PPG sensor, combined with its snug design and advanced algorithm, ensures accurate heart rate tracking even during intense exercise or other physical activities.
