Solution:
Resting heart rate, also known as resting heart rate, refers to the number of heartbeats per minute in a awake, inactive and resting state.
The best time to measure your resting heart rate is at rest in the morning after you are naturally awake. The resting heart rate of adults is usually in the range of 50~100 beats/min, and the resting heart rate of professional athletes is usually 40~60 beats/min. Since the automatic measurement by the watch may not be in the best time, it may cause the resting heart rate. The value is temporarily not displayed or the test value deviates from the actual value.
