The Redmi Watch 5 Active generally offers reliable heart rate monitoring, especially during resting conditions or moderate activities like walking. However, its accuracy can be affected by several factors, particularly during intense or dynamic exercises. Here are some scenarios where the heart rate monitoring might be less accurate:
1. Intense Workouts: During high-intensity exercises, such as extreme running or explosive workouts, the heart rate monitoring may not be as accurate. This is partly due to increased body temperature and sweat, which can interfere with the sensor's ability to detect heart rate signals accurately[3][6].
2. Wearing Position and Fit: The watch's fit on the wrist is crucial for accurate heart rate readings. If the watch is too loose or too tight, it can affect blood circulation and thus impact the accuracy of heart rate measurements. Ensuring the watch is snugly fitted just above the wrist bone is essential for optimal performance[2][6].
3. Skin and Hair Conditions: The presence of hair on the arm or variations in skin pigmentation can also affect the accuracy of heart rate monitoring. Lighter skin generally provides more accurate readings, while hairy arms can make it harder for the sensors to detect the pulse correctly[3].
4. Dynamic Movements: Activities involving rapid arm movements or significant arm swings might cause the watch to shift slightly on the wrist, leading to less accurate readings. This is because the sensor needs stable contact with the skin to function optimally[6].
In summary, while the Redmi Watch 5 Active provides good heart rate monitoring for casual use, its accuracy may be compromised during intense or dynamic exercises due to factors like sweat, body temperature, and the watch's fit on the wrist.
