Heart Rate Variability Status

Your watch analyzes your wrist heart rate readings while you are sleeping to determine your heart rate variability
(HRV). Training, physical activity, sleep, nutrition, and healthy habits all impact your heart rate variability. HRV
values can vary widely based on gender, age, and fitness level. A balanced HRV status may indicate positive
signs of health such as good training and recovery balance, greater cardiovascular fitness, and resilience to
stress. An unbalanced or poor status may be a sign of fatigue, greater recovery needs, or increased stress. For
best results, you should wear the watch while sleeping. The watch requires three weeks of consistent sleep data
to display your heart rate variability status.
