1) Heart Stress is stress response which is the reaction the body makes to a threat or challenge,
as determined from your HR measurements.
2) Mind Stress is stress feeling which is the level of stress you mentally “feel”. It’s a process of
cognitive and affective evaluation of a threat.
3) Our Sleep patterns are considered in your Overall Stress, where lack of sleep negatively
affects your Overall Stress, and more quality sleep reduces your Overall Stress.
You should aim to maintain your stress below 'red' levels, and continuously monitor your
Overall Stress levels over weeks and months to observe your trends and control your personal
health and wellness.
Heart Stress
Heart Stress is stress response which is a measurement of your body’s reaction to Stress
Feeling resulted from a threatening event or challenge. It is calculated based on your HR
measurements from the band, and normalized against population data. Note that the Mind
Stress is based on subjective impression of user while the Heart Stress provides an objective
reading of the body’s biological reaction to stressful event.
Sleep Quality
Sleep Quality = deep sleep / (deep sleep + light sleep)
Heart Age
This algorithm uses the user’s actual physical age as a base, and depending on the value of
user’s cardio parameters like HR and HRV as compared with data from population studies, it
outputs a computed “Heart Age” value.
Active Time
The Activity Monitoring algorithm utilizes data from a three-axis accelerometer sample, and
used to estimate a variety of output metrics for the detected motion states of sedentary,
walking, and running.
Active Time = walking time + running time.
