Health Smart Watch
The following points can make your wearable device get accurate heart rate tracking
• Make sure the smartwatch or fitness tracker fits snugly but comfortably on your arm, with the sensor flat on the skin above the wrist bone.
• Keep your smartwatch or fitness tracker clean (follow the directions), as sweat can interfere with readings.
• If you have poor circulation or feel cold, warm up a little before reading.
• Smoking or drinking alcohol before taking the measurement can cause your heart rate to differ from normal readings, and you can take the measurement again later.
