Why wear a tight bracelet when measuring heart rate?
The bracelet adopts the principle of light reflection and collects the signal reflected to the sensor
after the light source penetrates the skin to calculate your heart rate. If you wear it loosely, there
will be ambient light entering the sensor, which will affect the measurement accuracy.
