Why do my watch or fitness tracker's blood pressure and temperature differ?

Blood Pressure Measurement

Most watches or fitness trackers support blood pressure measurement.

The blood pressure data is calculated through a specific blood pressure algorithm, which is estimated based on the heart rate data obtained by the heart rate sensor. There may be certain differences.

Note: Blood pressure readings are for reference only and should not be used for medical diagnosis.

Temperature Measurement

This function measures wrist skin temperature, then calculates and displays as a temperature reading. Readings might be affected by how the device is worn, ambient temperature, and perceived body temperature.

Note: Temperature readings are for reference only and should not be used for medical diagnosis.

Note: Please tear off the plastic film on the sensor on the back of the watch or fitness tracker before measuring to avoid affecting the reflectivity and causing data deviation.
